Podcasts about headache disorders

Dr. Tesha Monteith talks with Dr. Peter Goadsby about advances in headache science and classification.  Read the fourth edition of the International Classification of Headache Disorders. Disclosures can be found at Neurology.org. 

In this brief podcast, I count down 10 unusual but unique headaches that may be perplexing for patients, and challenging for doctors to diagnose.

Orofacial pain comprises many disorders with different etiologies and pathophysiologies. A multidisciplinary approach combining medication, physical therapy, and procedural and psychological strategies is essential in treating patients with orofacial pain. In this episode, Teshamae Monteith, MD, FAAN, speaks with Meredith Barad, MD; Marcela Romero-Reyes, DDS, PhD, authors of the article “Orofacial Pain,” in the Continuum® October 2024 Pain Management in Neurology issue. Dr. Monteith is the associate editor of Continuum® Audio and an associate professor of clinical neurology at the University of Miami Miller School of Medicine in Miami, Florida. Dr. Barad is a clinical associate professor of anesthesiology, perioperative and pain medicine, and neurology and neurological sciences and codirector of the Stanford Facial Pain Program at Stanford Medicine in Stanford, California. Dr. Romero-Reyes is a clinical professor and director of the Brotman Facial Pain Clinic and Department of Neural and Pain Sciences at the University of Maryland in Baltimore, Maryland.

Dr Monteith: This is Dr Teshamae Monteith, associate editor of Continuum Audio. Today I'm interviewing Drs Meredith Barad and Marcela Romero-Reyes about their article on oralfacial pain, which appears in the October 2024 Continuum issue on pain management and neurology. Welcome to the podcast, ladies. How are you?  Dr Barad: Excellent.  Dr Romero-Reyes: Fine, happy to be here.  Dr Monteith: I am so happy to see you. I mean, I think both of you I've known for like ten years. Dr Romero-Reyes: Yeah.  Dr Barad: Yes.  Dr Monteith: So why don't you introduce yourselves? While I know you, our audience, some of them, may not know you.  Dr Romero-Reyes: I'm Dr Marcella Romero Reyes. I am a neuropathial pain specialist, clinical professor, and director of the Provident Special Pain Clinic here in the University of Maryland School of Dentist. Dr Monteith: Excellent.  Dr Barad: My name is Meredith Barad. I'm a clinical associate professor at Stanford and I work- I'm the codirector of our headache and facial pain clinic in the Stanford pain management clinic. Dr Monteith: Well, first of all, thank you for writing this article. It is extremely detailed and up-to-date and very informative. And in neurology, I think we don't get enough pain management. I'm interested in both of your backgrounds and, you know, what led you even to become an expert in this area? And both of you have complementary areas. I think we can see in the quality of this article. But why don't we start with you, Dr Romero-Reyes? Dr Romero-Reyes: Well, for me to get interested in orofacial pain, I will say more than an interest was like a calling that I wanted to take care of this patient population. So, as you know, my background is dentistry and at that time I was very interested in patients with complex medical issues. And was the time I was- I started to be interested in temporomandibular disorders. But what really picked completely my attention was the first time I saw a patient with trigeminal neuralgia. This was my last year in dental school. This patient already had, like, almost a full upper quadrant of teeth extracted where pain was not resolved. So when the patient came to us and I did my exam and, you know, and I triggered the pain, the sharp shoot electrical pain, that really broke my heart. And I took an x-ray and I didn't find anything that will explain it was something wrong until I talked to my professor and he said, no, this is medical. There's nothing wrong with it, with that tooth and needs to be, you know, followed with proper management and medication. And for me, that was like, wow, what a proper diagnosis and proper management can take care of these of these patients. And when the patient got better, that really said, oh, you know, I want to do this.  Dr Monteith: That's a crazy story. It's always that last patient of the day.  Dr Romero-Reyes: And you know, think about it, at least in dentistry at that time, I learned about trigeminal neuralgia from a book, right, my classes. But when you see the patient, this is it. That completely, you know, made me say yes, I want to study this.  Dr Monteith: Yeah. And unfortunately, that's not an uncommon scenario where patients with trigeminal neuralgia get, you know, their extractions and pain can sometimes be more complicated. What about you, Dr Barad? Dr Barad: Well, I guess I'm sort of like the opposite. So as a neurologist and a trained pain physician, I saw a lot of patients with neuralgic pain and headache pain, but I also saw many patients who would say, I have TMJ. And as, as Dr Romero has educated us, that's like saying I have shoulder or I have knee. But I quickly realized that I needed to work with a multidisciplinary team to really understand more about orofacial pain. It's not just neuralgic. There are other ideologies. And so that's how we started working together and that's how we practice in our clinic at Stanford. Dr Monteith: So, why don't you tell us about the objectives of this article? Dr Barad: I think our objectives were to help the neurologist broaden the differential diagnosis on facial pain to encompass below the nose, the oral cavity, the temporal mandibular joint. And to just think more broadly about facial pain and to understand some of the more recent diagnostic criteria that have been developed for facial pain and to- how to diagnose properly and how to begin treatment for some of the other conditions that are non-neurologic.  Dr Romero-Reyes: And I think I will ask about what Dr Barad say that also to bring awareness to the neurologist about the vast classification of oral facial pain disorder, craniofacial and orofacial. I think that was also a key thing too. And also, to show how well we can work together, you know, the multi-disciplinary management that is indicated for these cases. Dr Monteith: Cool. And you mentioned some of the new diagnostic criteria. I want to talk just briefly about the new international classification of orofacial pain, ICOP. When did that come out and what was the process there in really fine-tuning the diagnosis of orofacial pain disorders? Dr Romero-Reyes: So, in 2019 the orofacial head pain especially interest group of the International Association for the Study of Pain, the International Network for Orofacial Pain and Related Disorders methodology and the American Academy of Orofacial Pain and the International Headache Society. They partnered together to develop to develop this international classification of orofacial pain. And these, I think- it's such a great effort, you know, all the main people doing pain about this area, and goes very well together with the international classification of headache disorders. So, for example, you know, some disorders that International Classification of Headache Disorders doesn't present such as and the ICOP, International Classification of Orofacial Pain, presents, like the persistent idiopathic dental Viola pain. You have it in the ICOP. It's not, you know, mentioned in the in the International Classification of Headache Disorders, as well as, also we have the- I think it's item number five, the orofacial representations headache disorder or primary headache disorder. The ICOP gives you a nice, clean diagnostic criteria.  Dr Monteith: So, I guess I would ask Dr Barad with this classification in mind, how useful is it in neurology practice? And I know obviously you see patients with pain, but how useful even in managing patients with headache? Dr Barad: I think it's great because I've had a lot of dentists and ENT doctors who have started referring patients to me because they've realized that they've increased their awareness about orofacial pain and realized that pain in the sinuses, for example, accompanied by light sensitivity and sound sensitivity and rhinorrhea, may not be a recurrent monthly sinus infection. And so that kind of broadens our awareness of these of these disorders. And it's been, it's brought new patients into my clinic that we can help and treat. So that's been exciting.  Dr Monteith: And what about in the world of dentistry? Obviously, I think people in orofacial pain worlds are highly attuned to this, but I would hope this would hopefully have been disseminated into dentists and regular practice at C patients with trigeminal neuralgia. Dr Romero-Reyes: Going back for the, what you were discussing about the ICOP. So, it's what we're trying now as a new specialty. Well that we have been for the last four years, but finally in 2020 we have been recognized by the American Mental Association to disseminate this knowledge. But also, you know, can you imagine in in the realm in orofacial pain or dentistry have a patient with this recurrent pain, phonophobia, photophobia, throbbing dental pain is throbbing, but it's nothing wrong with your tooth. And that did they tell you that actually you have an orofacial or facial migraine or a neurovascular or facial pain. How crazy, right? And that is managed with migraines therapy. So it really, you know, to make you think like that. Wow, so these weird tooth things that used to come every week or these with facial pain, it's nothing to deal with, you know, with my teeth or any structure, you know, inside my mouth. Dr Barad: It sounds to me like what you're saying is that we've, this has encouraged patient education as well, not only interdisciplinary education, but really helping provide an explanation for the patient about what is going on with them. So rather than just getting sent away to another tertiary specialist, the patient is getting a more robust understanding of what's going on.  Dr Romero-Reyes: And going back to what you were saying about trigeminal neuralgia, you know, at least in dentistry also we're teaching now a new awareness like for two things, right? What about from the neurology setting? The patient has captured electrical pain. The trigger is intraoral. If it's pain inside your mouth, the first practitioner you're going to see who will be maybe the dentist that the dentist knows that could be a possibility of a disorder that doesn't deal with teeth, but also, it's important and we discussed that in our paper. What about that actually that weird trigger actually, it's not a general. What about if it's a cracked tooth has that singing sensation too. So, you see, it's two ways; one, to teach dentist to learn about this disorder and you know, we have learned, but you know, it's much more awareness now that this is great that, you know, these disorders you're not going to treat with dental procedures. Right? It's medical and vice versa, that the neurologist also has the awareness that oh, central trigger. Have you gone to the to the dentist? Have you checked that out? Dr Monteith: So what should neurologist know about dental sources of pain? Dr Barad: Well, maybe they should read the paper?  Dr Romero-Reyes: Yeah. Yeah, you need to read the paper. Yeah.  Dr Monteith: Top three, don't treat this with gabapentin.  Dr Romero-Reyes: Like well, dental pain is not going to be resolved with gabapentin. That would need to make a diagnosis if and you know it's that examination that come comes with a radiographic evidence that shows that maybe could be a cavity or could be a problem. You know in the in the practical tissues of the tooth that is given a symptomatology. Not only dental could be a lot of different disorders inside there now that can produce pain that also the readers can check our paper and learn about and see the wonderful interesting pictures that we have added there. Dr Monteith: Yeah. And so why don't we talk a little bit about TMD disorders and what is the new thinking around these conditions? Dr Romero-Reyes: Well, I will say for the last decade, maybe a little bit more has been a change in the evidence. They evidence based understanding of the theologia pathophysiologist and for mandibular disorders. Imagine that what's the shift in the in the paradigm that in dentistry prevails for a long, long time. That is that really focus and I will call it the pathological mechanistic point of view. What I mean by that I was focusing your bite, your occlusion, how the relation between in your maxilla mandible. That was the only issues that would create in temporomandibular disorders. So now we know that temporomandibular disorders are complex, are multifactorial and you need to understand them and see them within a biopsychosocial framework. And this dictate the main way to management for the primary way that we start will be conservative, reversible and basing evidence that the best evidence available that we have. Dr Monteith: And what about for trigeminal neuralgia? Is there newer kind of classification around trigeminal neuralgia? and what are some key points that we should consider when diagnosing these patients and treating these patients, Dr Barad?  Dr Barad: There haven't been any new diagnostic criteria, but I would say that there's been an increased awareness that classical trigeminal neuralgia is more likely than not related to neurovascular compression or we should say, maybe I should say neurovascular contact or compression. There is a developing grading system of that. That's an evolution as we speak. I think it's an exciting time for facial neuralgia because it's opened the door for us to look at other neuralgia also as vascular compressions and to think about how we can treat them with decompression or possibly with peripheral nerve stimulation or medicine or Botox. Or who knows what's the future is going to hold? But it is I think a change in the way we are thinking about the definition of neuralgia of, of trigeminal neuralgia in that is caused by a compression which is different than other neuralgia in other parts of the body. I should, I just want to classify there's about maybe ten twelve percent of people who present with classical trigeminal neuralgia who there is not evidence on imaging of a vascular contact or compression. But the majority of cases do seem to have some somewhere in the spectrum from contact to compression.  Dr Monteith: Even contact I find to be a bit vague sometimes say, well, thanks for letting me know that they're touching. But and then some of the neurosurgeons have different perspective when you open the patient up. So, I didn't know about the grading.  Dr Barad: Yeah, I think you've hit on it exactly like that is a big problem in the field right now. How do we understand what patients will be the best patients for surgery? And it used to be that you have the classical trigeminal neurologist symptomology plus some imaging that shows something versus nothing. And now we're getting into parsing out the imaging and trying to understand who's the best candidate for that with the imaging.  Dr Monteith: Dr Romero, anything to add?  Dr Romero-Reyes: No, that I agree about that, you know, and I think now maybe for the patients that I have seen with that, because under partial pain settings, sometimes we're the ones that, oh, actually what you have is trigeminal neuralgia idea, you know, so we start to have our small disciplinary management, but you know, when they come out, I already have an MRI doctor, but, and they say that these are compression, but what degree? And some patients that they don't have symptoms can have a compression. And I'm thinking maybe right that later on when we have more time and maybe nicer imaging, we're going to really find out or if it's the development angle is the measurement has some other characteristics, who knows. So, I think for trigeminal neuralgia, the things is still evolving, right? For our understanding. I have to help us to make a more- I will not say definitive diagnosis, but maybe some parameters will change in the future. Dr Monteith: So now we have a lot of people listening, international folks listening, and they always want some treatment, a tip, some clinical tips. So, can you give us a little bit of clinical insight to how to treat patients with trigeminal neuralgia and when you're seeing patients for second and third opinions, what might you see that may explain why their pain is not well controlled? We all get into interdisciplinary care, but in terms of pharmacology? Dr Barad: I think people are a little reluctant to use some of these medications that neuromodulating medications because, in general, it's an older population and they're rightly worried about falls and dizziness and confusion and low sodium. And so, I think they hesitate to go to the doses that are needed to help with pain control. So, a lot of our, my initial management is gingerly and gently titrating that to try to get to see if we can get control of the pain. Dr Monteith: Dr Romero?  Dr Romero-Reyes: I could add, for example, one thing that I in the realm of facial pain addition to pharmacology. Let's say that we have a patient with that intraoral trigger and we were able to localize that intraoral trigger. Sometimes we can even also use topical medication. And in the topical medication we can use, for example, an anticonvulsant, let's say gabapentin, oxcarbazepine for example, to add in the cream. And we use, we call it a neurosensory stent in my looks like a Nygard, but it's not a Nygard that can cover that area. So, the patient can add that cream very delimited in that area. And that helps, you know, can help with the pain sometimes. What we can find is that, at least in my, in my experience, and that when we add a topical, maybe we don't need to increase as much. The systemic medication, of course, depends from case to case.  Dr Monteith: So those are two great tips. Not being afraid to push those doses up in a safe manner and maybe with monitoring as well as of maybe utilizing more topicals. And I think we could probably hear a lot more from you on topicals at some other point. But thank you also for the table. I think it's, it's really nice the way all the treatments are laid out. So what other cranial neuralgia advances have there been? Dr Barad: I would say the main advancements have been in applying the knowledge that neurosurgeons have learned from microvascular decompression of the trigeminal nerve, to the glossopharyngeal nerve, to the geniculate nerve, and really trying to optimize imaging and optimize neurosurgical techniques to try to treat these neuralgias. If the patient has failed medicine, if the patient is a good candidate for surgery and if the patient desires that. Dr Monteith: Great. So now let's talk about multidisciplinary approaches. I know both of you are big fans of that, and you may do things a little bit differently at your institution, especially with your background. So maybe Dr Romero, do you want to tell us about your experience? And then we'll have Dr Brad. Dr Romero-Reyes: But in my experience from study management, let's say depend, of course, also the started we're talking about. But let's say for example about temporomandibular disorders, you know that for TMD is one of these overlapping pain conditions and we know that TMD is common with primary headache disorders, especially migraine. So, if we're able to utilize, you know, the expertise of neurologist specializing headache. With me, for example, or a facial pain person that is that is helping you manage a patient with this comorbidity. This is super effective because we know the presence of TMD in a migraineur can help the disorder to, to progress some more chronic form. So, you see, this is super important and effective to provide, you know, optimal care for the patient. For example, in the patients that I do see with neuralgias, like in addition to trigeminal neuralgia, let's say nervous intermediates neuralgia, that sometimes they can come to me like, oh, the pain is in my ear and my EMT or, or I think maybe it's my TMJ and for the pain is charged shooting inside the ear doesn't follow the for the diagnosis of temporomandibular disorders. And I can maybe help the patient to get a proper imaging or already penalize it with a neurologist to make sure. And maybe at least my way will be maybe I'm the one that can catch those disorders and help, you know, the patient to go for the next step. Dr Barad: I think Marcella, Dr Romero-Reyes, hit on a nice point that maybe this group is not as familiar with and that is that temporal mandibular dysfunction TMD is a, is one of the disorders that we call chronic overlapping pain conditions or COCPs. And those include headache. it's not, it's not specified fibromyalgia, irritable bowel syndrome, chronic pelvic pain and several other chronic pain syndromes. And they suggest a central sensitization to one's pain. And the way that we treat centrally sensitized pain is not just through medications, it's in a biopsychosocial framework because we see much higher rates of depression and anxiety in this group. And so, using a pain psychologist to help the patient develop coping strategies to help them manage their pain, using a physical therapist to help them learn this, the stretching exercises and using medications to help with not only with their pain syndrome, but also sometimes with their psych comorbidities. And then additionally, procedures sometimes play a role in the process to help usually turn down the pain. Interestingly, when we look at trigeminal neuralgia, we see much less overlapping pain disorders. It's much rarer to see somebody with TN who has other COCPs or the kind of chronic levels of depression and anxiety that we see in these patients. So, the approach is very different, and I think it requires the use of a multidisciplinary team to help guide the treatment pathways for these patients.

Today, I've got the great pleasure of interviewing Dr Peter Goadsby on indomethacin-responsive headache disorders, which is part of the April 2024 Continuum issue on headache. Dr. Goadsby is a Professor of Neurology at King's College London, in London, United Kingdom and a Professor Emeritus of Neurology at the University of California, Los Angeles, which is located in Los Angeles, California. Dr Goadsby, welcome to the podcast. Well Peter, I'm super excited to have the opportunity to talk to you. And I think, before we begin, we probably ought to expand on your introduction. I think there may be three or four neurologists who don't know who you are, and I think they should know who you are because you've got a really amazing story. These are exciting times in headache, right? And a lot of that's because of your work and you've been widely acknowledged for that; you received the appropriately named “Brain Prize,” which (if I'm correct) is the largest neuroscience award in the world; got to meet Danish royalty; you're - more recently, the ABF Scientific Breakthrough Award, which is super excited. So, particularly interested in hearing about your Continuum article. But before we get there, I think it would be really great to hear your story. How did you get into this in the beginning, and what's inspired you along the way to the many achievements you've had? Dr Goadsby: Why, it's a very kind introduction. People have been nice to me. It has to be said, Danish royalty were very nice, I have to say, and the very jolly chap, the Prince of Denmark. I got into neurology - I guess it's all about mentoring for me. I got into neurology because I got into medical school pretty much by accident. I really wasn't that interested and heard a lecture by James Lance, who was Professor of Neurology, University of New South Wales, at the time. He was talking about a nondominant parietal lobe. I'd seen the case as a medical student; it sort of just seemed weird to me and I wasn't that interested. But he set out this way of thinking about things to try and understand why a clinical presentation is what it is - what he described as a physiological approach to clinical neurology. He described a number of things, but he described that in this lecture and then gave a reference to some work that Mountcastle did on nondominant parietal recordings from awake behaving monkeys in the Journal of Neurophysiology. And I thought to myself, “Wow, this is really interesting - you could really get to the bottom of something,” and had that sort of “puzzle-y” thing going on. And I thought Lance was just wonderful, so I became interested in that. And then eventually I asked him about research - actually, I asked him about research after a lecture he gave on migraine, and the explanation of the time was some circulating substance - probably just as silly now. I went up to him afterwards and said to him, I thought the explanation he was giving was wrong. Like, here was a global person - he described Lance-Adams syndrome; this was someone who trained at Mass General, trained at Queen Square; was the first professor of neurology in Australia. I was just – like, it was a stupid thing to do. But I couldn't resist myself - I told him I thought it was wrong. And he's very polite, and he said, “Well, perhaps you could come and help us by doing some research.” And I thought, “Okay, that's a very nice response.” Interestingly, his daughter described him as unfailingly polite at his funeral. Of the many things you'd say about him, he was a kind person. Whether it's science or just the way you practice - that word (kind) - you can know as much about a subject as you like, but if you're not kind to patients, you're probably in the wrong game. He taught me to be curious about a problem and got me interested in headache, and to be kind in clinical practice - just kind – and I think they were very important lessons. So, I got into it because of excellent mentoring, and I'd like to think I've helped some others along the way. Dr Smith: Well, you certainly have helped a lot of people, Peter, and what a great story. I'm reflecting - I think the first vignette in The Man Who Mistook His Wife for a Hat was a right parietal syndrome - wasn't it? You've read that book? Dr Goadsby: Yes, I have. And I've met Sacks. When Sacks came to Australia, he wanted to see Lance, and Lance said, “Fine, but you have to meet me between the morning round and the afternoon clinical meeting.” And he got him to come and have lunch with him in the hospital cafeteria at the Prince Henry Hospital and invited me to this lunch. And I sat there and watched them chat. But it was a measure of Lance and how people were interested in him that Oliver Sacks had to get in a taxi and come out to a hospital cafeteria to have lunch if you wanted to have a chat. Because it was - it was a privilege to train with the person. You know, I've done okay, but I only do okay if you've got – you know, you can work with patients, you've got great collaborators, and you've got someone you can get advice from (a great mentor). Dr Smith: Yeah, that's actually really great words of wisdom for the residents and fellows and junior faculty listening to this. Maybe we should actually talk about your article, which was really great. Your article was on indomethacin-responsive headaches - and we can maybe talk about some specific questions - but what's the main take-home point? If our listeners needed to take or were to take home one point from your article, what would it be, other than it's indomethacin-responsive (that's in the title)? Dr Goadsby: Yeah, it's what it says on the jar. Well, I think the one thing to take home is that there are forms of headache that seem relatively pedestrian, like one-sided headache that feels like it ought to be migraine that's strictly one-sided, and a small percentage of them respond almost like switching a light off to indomethacin. So, I think you have to have a high index of suspicion. And I'm sure I give indomethacin to ten, twenty times as many people - or thirty - who end up (or even more, probably) who end up having a response. But we do it for a short period of time. For those who get the response - I can tell you, when they come back, they're crying, their partners crying, or the other day I saw one, their child's crying, because all of a sudden, you've basically fixed the problem up. So, the message would be, if you've heard about something and it feels a bit “maybe, could be” - you've heard this indomethacin thing - just do it for a couple of weeks. The worst thing that can happen is nothing (nothing happens). For a couple of weeks, they're not going to have a problem with the tummy (and I'm not advocating taking people with a active gastric ulcer, trying to bump them off). But you cover them properly, you give them a short trial, and occasionally in your practice, you will be so rewarded by that - you will dance home. Dr Smith: Well, this is going to be my next question. There are very specific criteria, right, for defining cluster, SUNCT, SUNA (and there was a really great Continuum Audio conversation I had with Mark Burish I'll refer our listeners to about cluster, SUNCT, and SUNA), but the indomethacin-responsive headaches - and even migraine - that sounds to me, as someone who's not a headache person, like, that could be challenging to sort out. If you see someone who has consistent, unilateral headache, do you just do an indomethacin trial, or do you select based on other criteria from the classification system? Dr Goadsby: I'd like to think I was aware of the criteria, and I am. But the longer I practice, the more I'm inclined simply to give the indomethacin and get the question off the table because I don't think there's a sine qua non; there's nothing that will - apart from the indomethacin effect - there's nothing that will convince me 100% to be able to not do it. I've seen enough people who haven't clearly read the classification in detail (patients, I mean) and took indomethacin, and got a response where you wouldn't have predicted it, and they're very happy and the story ends well. So, I would advise people not to worry too much about whether it ought to or not respond, but find out if it does. Dr Smith: So, the obvious next question is, how does this work? It's pretty unusual in medicine, certainly in neurology, to have something that's so dramatically effective. What's the mechanism? Dr Goadsby: Well, that's the easiest question - we don't understand it. It is particular to indomethacin - it's weird. Some patients will say, “We'll give you a little bit of a hint by telling you (maybe) that ibuprofen was useful,” but most don't give you that much of a hint (some will even say aspirin is useful). But we haven't really gotten to the bottom of it. What are the current thoughts? It must be something that's not simply cyclo-oxygenase because other cyclo-oxygenase inhibitors don't do that – so, that's helpful. The other broad things people think about are whether there's a nitrergic aspect to it. We've got some basic science work that can show that nitrergically induced changes in experimental animal model of these trigeminal autonomic cephalalgias can be modified by indomethacin in one part of the model, where naproxen (for example) can't. So, we think there may be a nitrergic component to it. The other thing is the structure of the molecule makes you think about melatonin, if you put the two up – it's a work in progress. Of the things I would like to do in my life, I'd really like to get to the bottom of it, I have to tell you, because if we could work out what it is that's great about indomethacin and then get rid of the GI thing . . . Then, if you talk about cure - because when people get a response to this (you know, the oldest reported case with a response took it for thirty-seven years; they died of something else) - and continue to respond. It's one of the sort of upsides and downsides when you diagnose it - you can tell a person that they're going to continue to respond (take a breath) until they die basically, because unfortunately, the problem doesn't tend to settle down - at least the treatment stays consistent. If we could get rid of the tummy problem, that would be real progress. Dr Smith: So, what do you do with the patient who has the tummy problem? Is there another approach? Dr Goadsby: Well, there's a range of things you try and do; you use PPIs (proton pump inhibitors) and H2 blockers pretty liberally; you try to get the lowest dose, and that's usually best done by the patient. I give them the ordinary-release indomethacin; it's an impression that I have, over the years, that the slow-release indomethacin is not as efficient (just as a recommendation). I let patients - they take it three times a day, or twice - I let them work out what the littlest amount is that they need, having given them a regime to iron it out, because they can work it out for themselves. It's a partnership. It'll be very individual. If someone wants to take two in the morning and one at night and feels happy, have at it. If they want to take one three times a day, if they want to take one at lunchtime - whatever they - let them work out the minimal amount. And the other thing that we found useful - small percentage (maybe one in five) will find the coxibs useful (like celecoxib), but that's not universal at all; it generally takes the edge off. A palpable percentage will find adding melatonin in can be indomethacin sparing. Then the other (probably most important) thing is that the noninvasive vagal nerve stimulator can be very useful in reducing indomethacin dosing or even getting patients entirely off indomethacin dosing. How that works, of course, is as mysterious in the sense of these problems as is indomethacin. But that's something really worth thinking about - can be very, very useful in getting the doses down. Dr Smith: You've been doing this for a while, right? And you've seen a lot of – Dr Goadsby: Let's not emphasize that “for a while” side, right, okay? Dr Smith: For a while – just a little while, Peter. Dr Goadsby: A little while. Dr Smith: I'm just thinking - and I'm a neuromuscular guy, so give me a little latitude - but when I was a resident, our concept of headache was pretty simple; it was migraine, classic or common, and we knew a little bit about cluster. And no one talked about SUNCT or SUNA or all these other things, and wow, what an amazing several decades it's been. What's the future look like? And - maybe think big – so, is a cure for migraine in the foreseeable future? What's coming next? Dr Goadsby: If you think really big (and I'll think really big), if “cure” means that we could control it sufficiently that you wouldn't notice it, I think that's very much - it's almost here, for some. Now, I think of it like cholesterol - someone's got high cholesterol; they take a statin, and if they don't get any problems, the cholesterol normalizes. I'm simplifying things (I'm not a cardiologist), but you take your cholesterol tablet - you take it once a day; everything's fine and dandy. You never get “cured,” as such, but the effect is an effective cure from manifestations of the problem - and I am simplifying things a little bit. If I look at it like that, then I think we're getting to a place where some patients, we can treat them so well, and the problem is so suppressed, and they have so few problems with side effects (and some have none), that we're really getting there. We saw a study of the promontory phase of migraine using a gepant (ubrogepant), and we saw the ability (if you recognize the attack early enough) to treat and never have pain. Never have pain. Well, that's pretty close. It might sound crazy to think about it as a cure because someone will say, “Well, they've still got their genes,” and so on. Fine. But migraine is about disability, and if you can stop the disability and give a person full function in their life, well, you're pretty much there. And we're getting there, as we understand the disease. Dr Smith: Really amazing. I have another question that I've actually been really dying to ask you. I'm a peripheral nerve guy, and you may not be aware of this, but those of us who are interested in therapeutic development in peripheral neuropathy, or advocacy, or recognition of neuropathy as a substantive, meaningful entity, are inspired by the work of you and your colleagues in headache. Examples might be advocacy for federal funding or having CDMRP funding - things like this. But an area where - I'm just curious - we spent a lot of effort (and it seems like it's been really transformational for you guys) is having taxonomy, which isn't a particularly sexy topic. But maybe you can talk about the power of having a taxonomic classification and getting towards a cure. Because looking through this Continuum issue - it's really remarkable – it's just all sorts of things that I never would have thought of twenty years ago, and each of them is treated a bit differently. Dr Goadsby: Yes. As with all things in medicine, if you don't get the diagnosis, you can't get to the base - you've got to be able to get a diagnosis. And our taxonomy, the International Classification of Headache Disorders, has gone through three editions. We're working on the fourth. I have the privilege of being the chairman for the fourth edition (the first three were chaired by Jes Olesen). I do think it's one of the absolute achievements of our field (and Olesen needs to be really feted for doing this) that we have a definition system - it's operational; it's reasonably straightforward; it's been translated into, like, forty languages; that every government on the planet that I know of - and I'm talking about (I think I'd better mention no governments) but every big government you can think of, without exception, has adopted (‘cause I'll just get in trouble with the ones I've mentioned) have all adopted this classification; all the health technology assessments (the FDA, for example; the European Medicine, for another example), the Chinese government (People's Republic), Taiwan. Just, all over the world, people use one thing. So, if we do a randomized control trial - there's one recently came out; it doesn't really matter which gepant it is - but you look at the results in North America, and then you look at the results that were done by the Chinese and the South Koreans in a study, and the placebo rates and the active rates are more or less identical. Because what we've been able to do is homogenize who gets into clinical trials and understand what's happening. So, if I get up and talk about whatever we're going to talk about now, like, in rural India, people will know what we're talking about; all the neurologists will be on the same page and so we can make progress. And when we make progress, it's global progress because we sing from the same hymn sheets. I think the taxonomy has been really important for this. And, of course, if you get the diagnosis right, then you can start to begin to get the treatments right and you can bring all the knowledge from randomized controlled trials. There's no point having a whole lot of data if you can't apply it, and what's great about our taxonomy is we can apply it everywhere in the world. Dr Smith: Wow, what a cool answer. So, I have a follow up question for you, Peter, which has to do with reproducibility. This is a huge issue, right? In reproducibility and clinical trial evidence and in many fields, this has been a big issue - in psychiatry and other areas of neurology, where trials are nonreproducible. To what extent do you think this problem in other fields is a taxonomic problem, or a internal validity problem, in terms of the populations being recruited? I'm really impressed to hear that you don't have that problem in headache. Dr Goadsby: I do think one of the advantages that the International Classification of Headache Disorders has given us (International Headache Society being the proponent of that) is that there's clinical homogeneity, relatively speaking, in our clinical trial populations. This comes back to the clinic; good clinical trials are as much about the clinicians who are involved and the care they take in recruiting patients, and so on. Which is not to say that psychiatrists are not careful - not at all. But I do think that if you want to just test a question, everyone in the laboratory will tell you that you need to have - say you're doing work with rodents, for example; you want about the same weight, you want the same strain, they're eating about the same, they're up and down at night - everything is about the same. If you want to do good clinical trial work, you have to tidy up as much as you can so the only thing that's really impacting upon the question is the medicine, or the placebo, or whatever that you're testing. So, I think you're right. I think sometimes the pain people struggle with this because, as you say, a painful neuropathy can come from a lot of places. Well, if you just take all of those etiologies, you throw them into one study, and you test it against something, it doesn't surprise me that that's not so useful, compared to taking an individual thing that's really well defined - where you've understood the clinical side, you've understood the pathophysiology as much as you could - and just test that, one at a time. I think that's been a good lesson for us. And that's why there's nothing that's ever failed in a migraine clinical trial (a properly designed one) that ever was useful, and nothing that was ever successful that didn't continue to be successful. Now, some things were successful, and they produced, like, liver enzyme problems - so, that's “no win-no foul” situation. But the homogeneity's been quite important, I think. And it comes back to good clinical practice. Dr Smith: Well, thank you for the roadmap - that's really, really interesting. I'd like to finish up with another shift in gears, and to talk about workforce. Obviously, we have a national shortage of neurologists in the United States. We're never going to be able to train enough headache neurologists to take care of all headache patients, and we need to think about systems of care, which I guess we could talk about. But my question for you is, what would you say - a lot of residents listen to Continuum Audio, and hopefully, more medical students in the future and now - what do you say to them about a career in headache? Listening to this, I kind of feel like I want to go do a headache fellowship - it's pretty exciting. What's your pitch to them? Dr Goadsby: I'll tell you one small thing first before I say that; I did do twelve months in clinical neurophysiology, doing nerve conduction, muscle biopsies, evoked potentials. I actually did over ninety muscle biopsies (needle muscle biopsies) when I was training, so I understand your feeling. But I just got the feeling many years earlier than you've had it. What do I say to residents? Well, headache is an area where you can make a diagnosis, you can manage the patient, and you can make them better. I'd say to the resident, “Ask - just look in the mirror and ask yourself, why did you get into medicine?” You got into medicine to help people, and headache is an area where you can really help them. Plus, there's tens of millions of people with the problem, so you will always be in demand. And one of the great things about headache (I think it's probably true of neuromuscular) is it's also a very good lifestyle choice because our problems are generally with primary headache disorders - are not emergent (people don't tend to ring you up at night), and it's not really an on-call issue. You can have a proper balanced existence (work-life balance), and you can do it in a way that's really enjoyable. And then there's an extra bonus: there's all the wonderful neuroscience and neuropharmacology that's going on in headache. I just think if a resident looks in the mirror and says, “Why am I doing this?” most of them are going to look back at themselves and say, “Because I want to do good.” And they also want to do good in a way that they can have a proper life themselves. And if they're the two answers you got back when you look in the mirror (“I want to do good” and “I want to have some life myself”) - headache - that's the place to go, because there's plenty of room and you can do both. Dr Smith: Well Peter, that's great - sign me up. And I think people know where to find you to call for a recommendation. What a great conversation and a really great article. And again, I'll refer our listeners to Mark Burish's article on cluster, which is a really great companion to your article ‘cause it gives you the full spectrum of trigeminal autonomic cephalgias (which is pretty cool), and the rest of the issue is equally amazing. Peter, you don't disappoint. The next time you see the Danish Crown Prince, say “Hi” from me (I love Denmark - it's a lovely place to be). And thanks again for doing this. Dr Goadsby: Well, thank you, and thanks for the Academy for organizing. And the other thing about residents - if you want to stay in touch with neurology, stay in touch with the Academy; they're a pretty good bunch. Dr Smith: Couldn't agree more, couldn't agree more.

Dr Robbins is an Associate Professor of Neurology and Director of the Neurology Residency Program at New York-Presbyterian/Weill Cornell Medical Center, in New York. Welcome to the podcast. Dr Robbins: It's great to be with you, Dr Berkowitz. Dr Berkowitz: Well, thanks so much for joining us this morning. To start, what is new daily persistent headache? I think it's an entity maybe that might be new to some of our listeners. Dr Robbins: Yeah - it's an entity that also struck me when I was in training. I didn't hear much of it as a neurology trainee until I did a fellowship in headache, where, all of a sudden, we were seeing patients with this syndrome (and labeled as such) all the time. And that actually inspired me to begin a research project to better characterize it - a clinical project that ended up helping to broaden the diagnostic criteria. New daily persistent headache really is just defined by what it says - it's new; it's every day; it persists; it's a headache. It can't be from some other identifiable cause, which includes both secondary disorders (you know, something that, where headache is a symptom of) or a primary headache disorder; distinguishes itself from, say, migraine or tension-type headache because there's no real headache history and there's an abrupt onset of a daily and continuous headache that has to last for at least three months since onset. And the onset is typically remembered - it's usually acute or abrupt; there may or may not be some circumstances that surrounded the onset that might have some diagnostic or causal or associated implications that we can explore. Dr Berkowitz: Okay. So, I always find it challenging in headache medicine and some other areas where we don't have a biomarker, per se - an imaging finding, a lab finding; we have an eloquent and detailed clinical description - to know how comfortable to be making a diagnosis like this. In this case, particularly, right - you said it has to be going on for three months. What if I see a patient one month into something I think could be this, but I can't technically say, per the criteria, right (it's three months)? When do you start thinking about this diagnosis in patients, and what are some of the main considerations in confirming the diagnosis, and what needs to be ruled out or excluded for making the diagnosis?   Dr Robbins: I think traditionally, in headache, the term “chronic” has that three-month time period. The reasons are twofold: one is that, typically, if there's some secondary disorder that might have some distinguishing feature (something that really evokes the headache or some other neurological accompaniment that develops in addition to headache), it would pretty much be likely to declare itself by the three-month mark. Or if it was something that was very self-limited, it would probably go away before three months have elapsed. Or if it resolved after some days or weeks but then declared itself as a more episodic disorder, then we might say someone who begins with continuous headache that might, for example, resemble migraine (maybe it presented a status migrainosis but then it devolved into a more episodic disorder that might just be migraine overall). So, I think that's pretty much why the three-month mark has been so prevalent in the International Classification of Headache Disorders, including how new daily persistent headache is diagnosed. But at the same time, there's lots of disorders that might mimic (or might be misdiagnosed as) new daily persistent headache, and they really are a secondary disorder. Probably the most common one that we think about is a disorder of intracranial pressure or volume, mainly because routine MRI features could be normal or could be easily missed if they had subtle abnormalities. The defining symptom of those disorders are also continuous headache, often from onset, with an abrupt and remembered nature. So, that's often the main category of secondary headache that might be misdiagnosed as primary headache. I think, probably, idiopathic intracranial hypertension as the prototypical disorder of high pressure often declares itself with visual symptoms, pulsatile tinnitus, and other abnormalities. And nowadays, there's much more increasing recognition for MRI abnormalities or even MRV abnormalities with such patients. But spontaneous intracranial hypotension (despite increasing recognition of CSF leaks in the spine that lead to intracranial hypotension or hypovolemia) really remains an underdiagnosed entity. I think that's one disorder where - for example, if I'm seeing a patient with new daily persistent headache and there's no orthostatic or positional nature to their headache - I will still do an MRI, with and without contrast, to be sure. But that the chances of them having a spontaneous CSF leak are low if that scan is unremarkable. Dr Berkowitz: That's very helpful. Yeah. It's interesting; when you talked about the criteria for this condition - that it has an acute onset, which is a red flag, right, and it is persistent for months, which for a new headache would also be a red flag. So, this is a condition - correct me if I'm wrong – that, if you're considering it, there's no way that you're going to make this diagnosis without neuroimaging because there are two red flags, in a way, embedded in the criteria before we get to the other diagnoses being excluded. Is that right? So, this would only be a diagnosis made clinically but after neuroimaging is obtained, given that two red flags are part of the criteria – isn't that right? Dr Robbins That's absolutely right. So, I can't imagine there's anyone who has new daily persistent headache who hasn't had appropriate neuroimaging, and that typically should include an MRI, with and without contrast, unless there's some compelling reason to avoid that. There's some other workup that could be done that's not universal but - for example, in clinic-based studies of patients who have new daily persistent headache versus those who may have, say, chronic migraine or chronic tension-type headache, you may find more abnormalities. The biggest and more compelling example of that is hypothyroidism, which presumably would be somewhat subclinical if it hadn't been brought to someone's medical attention earlier. It doesn't mean that hypothyroidism is the cause of new daily persistent headache, but it could be some type of triggering or priming factor that leads to headache perpetuation in some patients. Sometimes, if that hasn't been done already, that would be a blood test I might think about sending. And, of course, the context of onset; if someone lived in a place where tick-borne illnesses are endemic, if there are other neurological symptoms, that might prompt looking for serological evidence of Lyme disease, as one example. Dr Berkowitz: We see a lot of headache. I'm a general neurologist; I know you're a headache specialist; we all see a lot of patients with headache. You and I both work closely with residents. Often, residents will come to present a headache patient to me and they'll say, “The patient seems to have a new daily persistent headache. They haven't been imaged yet. They have a completely normal exam. The history fits.” And I always ask them, “Okay, we have to get neuroimaging, right? There's at least one red flag of the chronicity, maybe the red flag of something beginning relatively abruptly. Even though you're looking at the patients - I'm pretty sure that imaging is going to be normal, but we've got to do it.” But I always encourage residents, “Try to predict - do you think the imaging is going to be normal (this is a rule out) or do you think you're going to see something (this is a rule in)? - just to sort of work on calibrating your clinical judgment.” I'd love to ask you - as a headache specialist, when you're looking at the patient and say, “I know I need to get neuroimaging here to fully make this diagnosis of exclusion,” or you've heard something that sounds like a red flag; you know you're obligated to image, but your clinical suspicion of finding anything more than something incidental is pretty low. How often are you surprised in practice in a sort of enriched tertiary headache population? Dr Robbins: That's a great way to frame such a presentation on how a resident would present to you the case and whether it's a rule in or rule out. I totally agree with your approach. I think much of it depends on the clinical story. I think if it was just a spontaneous onset of headache that kind of resembles migraine that just continued, then likely the MRI is being done to just be sure we're not missing anything else. However, if the headache started – really, say someone coughed vigorously or bent over and the headache started, and there was some clear change that you could perceive in - that was, say, the Valsalva or a transiently raised intracranial pressure, or some other maneuver; then you might really say, “Well, this really could be a spontaneous CSF leak,” for example. Even if the MRI of the brain, with and without contrast, is totally normal, I'm not really sure I'm convinced - that you might even take it further. For example, you might do an MRI of the total spine, with a CSF-leak-type protocol, to see if there's some sign of a spontaneous CSF leak or an extradural collection. So, I think in the cases where the preclinical suspicion is higher for a secondary headache, it might not stop at an MRI of the brain (with and without contrast) that's normal. Patients with spontaneous CSF leaks - about eighty percent of them have abnormal brain MRIs, but twenty percent don't. We found, from some observational studies, that a newer cause of intracranial hypotension, such as a CSF venous fistula in the spine, is more likely to present than other causes of CSF leak - with say, Valsalva-associated headache or cough-associated headache. That might prompt us to really take a workup more deeply into that territory, rather than someone where it really just sounds like chronic migraine that switched on. And maybe in those patients, when you dig around, they were carsick as a kid, or they were colicky babies, or they used to get stomachaches and missed school as a teenager here and there, and you think migraine biology is at play. Dr Berkowitz: So, if you're thinking of this diagnosis before you can make it, these patients are going to get an MRI, with and without contrast. And it sounds like the main things you're looking to make sure you're not missing are idiopathic intracranial hypertension or intracranial hypotension from some type of leak. Any other secondary headaches you worry about potentially missing in these patients or want to rule out with any particular testing? Dr Robbins: Yeah - I think sometimes we think of other vascular disorders, especially - when these patients come to medical attention, it's often a total change from what they're used to experiencing. They may present to the emergency room. So, it depends on the circumstance. You might need to rule out cerebral venous thrombosis. Or if there was a very abrupt onset or a relapsing nature of abrupt-onset headaches with sort of interictal persistent headache, we might think of other arteriopathies, such as reversible cerebral vasoconstriction syndrome. There's the more common things to rule out - or commonly identified conditions to rule out - like neoplasm and maybe a Chiari malformation in certain circumstances; those usually would declare themselves pretty easily and obviously on scan or even on clinical exam. Dr Berkowitz: Another question I'd love to ask you as a headache specialist, in your population - sometimes we see this type of new daily persistent headache presentation in older patients, and the teaching is always to rule out giant cell arteritis with an ESR and CRP, in the sense that older patients can present with just headache. Again, my clinical experience as a general neurologist - I wanted to ask you as a headache specialist – is, for the countless times I've done this (older patient has gotten their neuroimaging; we've gotten ESR and CRP), I've never made a diagnosis of giant cell arteritis based on a headache alone, without jaw claudication, scalp tenderness, visual symptoms or signs. Have you picked this up just based on a new headache, older person, ESR, CRP? I'm going to keep doing it either way, but just curious - your experience. Dr. Robbins: Yeah. We're taught in the textbooks (I'm sure we're taught by past Continuum issues and maybe even in this very issue) about that dictum that's classically in neurology teaching. But I agree - I've never really seen pure daily headache from onset, without any other accompaniments, to end up being giant cell arteritis. Then again, someone like that might walk in tomorrow, and the epidemiology of giant cell arteritis supports doing that in people over the age of fifty. But almost always, it's not the answer; I totally agree with you. Dr Berkowitz: Good to compare notes on that one. Okay - so let's say you're considering this diagnosis. You've gotten your neuroimaging, you've gotten (if the patient is over fifty) your ESR and CRP, and you ruled out any dangerous secondary causes here. You have a nice discussion in your article about the primary headache differential diagnosis here. So, now we're sort of really getting into pure clinical reasoning, right, where we're looking at descriptions (colleagues like yourself and your colleagues have come up with these descriptions in the International Classification of Headache Disorders). Here again, we're in a “biomarker-free zone,” right? We're really going on the history alone. What are some of the other primary headache disorders that would be management changing here, were you to make a diagnosis of a separate primary headache disorder, as compared to new daily persistent headache? Dr Robbins: I think the two main disorders really are chronic migraine and chronic tension-type headache. Now, what we're taught about chronic migraine and chronic tension-type headache is that they are disorders that begin in their episodic counterparts (episodic migraine, episodic tension-type headache) and then they evolve, over time, to reach or culminate in this daily and continuous headache pattern, typically in the presence of risk factors for that epidemiologic shift we know to exist but that may happen on the individual level, which does include things that we can't modify, like increasing age, women more than men, some social determinants of health (like low socioeconomic status), a head injury (even if it didn't cause a concussion or clear TBI), a stressful life event, medication overuse, having comorbid psychiatric or pain disorders in addition to the headache problem, having sleep apnea that's untreated, and so on. New daily persistent headache - by definition, it should really be kind of “switched on.” Many years ago, Dr Bill Young and Dr. Jerry Swanson wrote an editorial where they labeled new daily persistent headache as the “switched-on headache.” Then, we're taught in headache pathophysiology that this chronification process happens over time because of, perhaps, markers of central sensitization that might clinically express itself as allodynia in trigeminal or extratrigeminal distributions. So, we're not comfortable with this new daily persistent headache, where we think the biology is like chronic migraine that gets switched on abruptly, but in so many patients, it seems to be so - it behaves like chronic migraine otherwise; the comorbidities might be the same; the treatments might still work similarly for both disorders in parallel. So, I think those are the two that we think about. Obviously, if there's unilateral headache, we might think of a trigeminal autonomic cephalalgia that's continuous, even if it doesn't have associated autonomic signs like ptosis or rhinorrhea (which is hemicrania continua) - and in those patients, we would think about a trial of indomethacin. But otherwise, I think chronic migraine and chronic tension-type headache are the two that phenotypically can look like new daily persistent headache. In patients with new daily persistent headache, about half have migraine-type features and about half have tension-type features. When I was a fellow, the International Headache Society and the classification only allowed for those who have more tension-type features to be diagnosed as new daily persistent headache. But we (and many other groups) have found that migraine-type features are very common in people who fulfill rigorously the criteria for new daily persistent headache otherwise. And then the latest iteration of the classification has allowed for us to apply that diagnosis to those with migraine features. Dr Berkowitz: That's very helpful. So, we've ruled out secondary causes and now you're really trying to get into the nuances of the history to determine, did this truly have its abrupt onset or did it evolve from an episodic migraine or tension-type headache? But it could be described by the patient as migrainous, be described by the patient as having tension features The key characteristics (as you mentioned a few times) should be abrupt onset and a continuous nature. Let's say, now you (by history) zeroed in on this diagnosis of new daily persistent headache. You've ruled out potential secondary causes. You're pretty convinced, based on the history, that this is the appropriate primary headache designation. How do you treat these patients? Dr Robbins: Well, that's a great question, Dr Berkowitz, because there's this notoriety to the syndrome that suggests that patients just don't respond to treatments at all. In clinical practice, I can't dispute that to a degree. I think, in general, people who have this syndrome seem to not respond as well, to those who have clear established primary headache disorders. Part of that might be the biology of the disorder; maybe the disorder is turned on by mechanisms that are different to migraine (even though it resembles chronic migraine) and therefore, the medications we know to work for migraine may not be as effective. In some, it could be other factors. There's just a resistance to appreciating that you have this headache disorder that - one day you were normal, the next day you're afflicted by headache that's continuous. And there's almost this nihilism that, “Nothing will work for me, because it's not fair - there's this injustice that I have this continuous headache problem.” And often people with new daily persistent headache may be resistant to, say, behavioral therapies that often are really helpful for migraine or tension-type headache because of this sort of difficult with adjustment to it. But at least there's observational studies that suggest that most of the treatments that work for migraine work for new daily persistent headache. There's been studies that show that people can respond to triptans. In my clinical experience, CGRP antagonists that work for the acute treatment of migraine may work. There is evidence that many of the traditional, older medicines (like tricyclic antidepressants, topiramate, valproate, beta-blockers, probably candesartan) and others that we use for migraine may work. There's observational studies specifically for new daily persistent headache that show that anti-CGRP therapies in the form of monoclonal antibodies and botulinum toxin can work for the disorder. Are there anything specific for some of the new daily persistent headache that might work? Not that we really know. There's been some attempts to say, “Well, if you get these people in the hospital early and try to reduce the risk of headache persistence by giving them DHE, or dexamethasone, or lidocaine, or ketamine, will you reduce the chances of headache persistence at that three-month mark or longer?” We don't really know (there's some people who believe that, though). Maybe there's good reason to do some type of elective hospitalization for aggressive treatment because we know that, notoriously, the treatment response is very mixed. There's been specific treatments that people have looked at. There's been some anecdotes about doxycycline as a broad anti-inflammatory type of treatment that might be used in a variety of neurological disorders, but there's really nothing in the peer-reviewed literature that suggests that is effective or safe, necessarily. And I think a lot of people in new daily persistent headache do develop a profile that resembles chronic migraine (they can develop medication overuse very easily). Often, goal setting is really important in the counseling of such patients. You really have to suggest that the goal for them might be difficult to have them pain-free at zero and cured, but we want this to be treated so the peaks of severity flatten out a bit, and then the baseline level of pain diminishes so that it devolves into a much more episodic disorder over time that looks like regular migraine or regular tension-type headache. Dr Berkowitz: I see. So, in addition to starting a migraine-type prophylactic agent based on the patient's comorbidities and potential benefits of the medication (the same way we would choose a migraine prophylactic), do you do anything, typically, to try to, quote, “break the cycle” - a quick pulse of steroids as an outpatient or a triptan in the office - and see how they do, or do you typically start a prophylactic agent and go from there? Dr Robbins: I think, like all things, it kind of depends on the distress of the patient and how they are functioning. If it's someone who's just out of work, cannot function - and someone like that might be very amenable to an elective hospitalization or some parenteral therapy, or maybe an earlier threshold to use a preventative treatment than we would be doing otherwise in someone with migraine overall - I think that it really depends on that type of a disability that's apparent early. I think it's compelling that, with new daily persistent headache, about a third of people report some antecedent infection that was around at the time. When new daily persistent headache was first described by this Canadian neurologist, Dr Vanast, in the 1980s, it was described in the context of Epstein-Barr virus infection, or at least a higher rate of serologies that are positive for, perhaps, recent Epstein-Barr exposure. And we know that Epstein-Barr is obviously implicated in lots of neurological diseases, like multiple sclerosis. And I mean, I think about these things all the time, and especially with COVID now. So, it's compelling - as a postinfectious disorder, do we, as neurologists (who are so comfortable with using pulse-dose steroids, IVIG) - do we use these things for a new daily persistent headache? But there's no great evidence that enduring inflammation in the dura that would spill into CSF analyses is really present in such patients. There was one study that looked at markers, such as TNF-alpha, in the CSF, but the rates of seeing that were the same in new daily persistent headache and chronic migraine, so there isn't really a specificity to that. Many people we see with new persistent headaches since 2020 may have it as part of a long COVID syndrome (or postacute COVID syndrome), and in those cases, often it's more like “new daily persistent headache-plus.” They might have something that resembles POTS (postural orthostatic tachycardia syndrome); they might have something that resembles fibromyalgia, chronic fatigue. Often in those patients, it takes management of the whole collection of neurological syndromes to get them better, not just the headache alone. Dr Berkowitz: Well, this sounds like such a challenging condition to treat. How do you counsel patients when you've made this diagnosis - what to expect, what the goals are, what this condition is, and how you developed your certainty? It's often challenging (isn't it?) sometimes with patients with headache disorders, when we're not relying on an MRI or lab test to say, “This is the diagnosis”; telling them, it's just our opinion, based on their collection of symptoms and signs. So, how do you give the diagnosis and how do you counsel patients on what it means to them? Dr Robbins: Yeah, it's a great question because it's high stakes, because people will read online, or on social media, or on support groups that this is a dreadful condition - that no one gets better, that they're going to be afflicted with this forever, and the doctors don't know what they're doing, and, “Just don't bother seeing them.” And the truth is not that; there's so many people who can get substantially better. I tell people that it's common; in some epidemiologic studies, one in one thousand people in any given year develop new daily persistent headache, and most of those people get better (they don't seek medical care eventually, or they do, just in the beginning, and then they don't have follow-up because they got all better) - and I think that really happens. I think the people who we see in, say, a headache clinic (or even in general neurology practice) are typically the ones who are the worst of the worst. But even amongst those, we see so many stories of people who get better. So, I really try to reset expectations - like we mentioned before about assessing for treatment response and understanding that improvement will not just mean one day it switches off like it switched on (which seems unfair), but that the spikes will flatten out of pain (first), that the baseline level of intensity will then improve (second); that we turn it into a more manageable day-to-day disorder that really will have less of an impact on someone's quality of life. Sometimes people embrace that and sometimes people have a hard time. But it does require, like many conditions in neurology, incremental care to get people better. Dr Berkowitz: Fantastic.

Dr. Schwedt is a Professor of Neurology at Mayo Clinic in Phoenix, Arizona. Welcome to the podcast today, Dr. Schwedt.    Dr Schwedt: Well, thanks so much. It's a real pleasure to be here.    Dr Berkowitz: Thanks. We're very happy to have you. So, head trauma is common, and headache following head trauma is also very common. Let's say you're seeing an otherwise healthy young patient in your clinic who had a minor car accident a few weeks ago with some head strike and whiplash, presenting now for evaluation of headache again a few weeks out from the accident. Walk us through your approach to the history and exam here when you're seeing one of these patients. Dr Schwedt: Yeah, absolutely. I'd be happy to do so. I'll start by saying, as you mentioned, this is such a common problem - patients that are coming in with post-traumatic headache). Of course, like almost everything in neurology, it's super important to get a detailed history to start with (so, doing the appropriate interview), and I usually like to start by getting some information about the injury itself - the mechanism of the injury, and the severity, and, of course, the symptoms that went along with the potential traumatic brain injury – so things we all know about. Then, of course, it's very important to understand how the patient felt prior to the injury because we know that, amongst people presenting with post-traumatic headache, oftentimes they might have had headaches even prior to their injury, and that's because having preinjury headaches is a risk factor for developing post-traumatic headache, as well as the persistence of that post-traumatic headache. If someone had headaches prior to their injury, then of course we want to know if that actually changed or not - is there a difference in the severity, or the frequency, or in the characteristics of the headaches they've been experiencing since their injury? Then, of course, you're going to ask about exactly what the symptoms are they're having now and what's concerning them the most, realizing that for a diagnosis of post-traumatic headache, it's very important to understand the timing of the onset of these headaches in relation to the injury. By definition, post-traumatic headache should have onset within seven days of the inciting traumatic brain injury - so the diagnosis of PTH, I mean, really is dependent upon that timing -  so, using ICHD (which is International Classification of Headache Disorders) criteria, it's got to start (or be reported to have started) within seven days. It's important to realize there are no specific headache characteristics that help to actually rule in or rule out post-traumatic headaches; the criteria themselves just say “any headache,” as long as it was within that seven-day period. Having said that, though, the vast majority of people who come into the clinic for evaluation - their post-traumatic headache is going to be very similar to migraine. So, like, in other words, if they didn't tell you and you didn't ask about when the headache started and you just asked about symptoms, it would seem a lot like migraines – so, very common for the headache to be moderate and severe in intensity, be associated with light sensitivity and sound sensitivity and nausea, be worse with physical and mental exertion (very much the migraine-type characteristics). As far as diagnosis, it's also, of course, important to think about other sequelae of traumatic brain injury that could be causing the headache. For example, if you're under the impression it's a mild traumatic brain injury, but in fact, there's an intracranial hemorrhage - it wouldn't necessarily be mild any longer, but of course, that could cause headaches. We should be thinking about whether there could have been injuries to the cervical spine or the musculature of the neck that could be causing more of a muscular, cervicogenic-type headache. Think about rare possibilities, like if there was a cervical artery dissection, or if there's actually a spinal fluid leak, or, again, other things that after an injury could be causing headache. Most of the time, that's not going to be the case and you would move forward with your diagnosis of post-traumatic headache.  Dr Berkowitz: Fantastic. That's very helpful to hear your approach. You just mentioned, as you said, most patients who've had minor head trauma and are presenting with headache, fortunately, have not suffered a cervical artery dissection or CSF leak or have an evolving subdural. But when you're in this early stage (just a few weeks after the initial injury) and there is headache, what features of the history or exam would clue you into thinking that this patient does need neuroimaging to look for some of these less common, but obviously very serious, sequelae of head trauma?  Dr Schwedt: So, it's things that, as neurologists, we all know about, right? But certainly, if you're concerned about a spinal fluid leak, then really someone who has a prominent orthostatic component to their headache (so, you know, much worse when they sit up or stand up, compared to lying down) could be concerning. With a cervical artery dissection, almost always you're going to have focal neurologic deficits in addition to the headaches. With intracranial hemorrhage - again, usually it's going to be fairly obvious, in that the symptoms that someone's presenting with are much more diffuse and more severe, and maybe they're actually having progression of symptoms over time rather than stability or even early improvement. Then, as we would always say, the exam is essential, right? I mean, certainly someone who's had a mild traumatic brain injury might have very subtle deficits in things like their cognition and memory of events around the injury itself - and perhaps some ocular motor deficits and some vestibular dysfunction - but they should be relatively minor compared to somebody who has one of these other etiologies for a postinjury headache. We'll point out, of course, not everyone requires imaging, again, as there's all these decision rules out there about who needs CT, for example, after an injury (and certainly not everyone does). But, you know, if people have red flags, then of course it makes sense to initially get a CT of the head, and then if symptoms persist, perhaps an MRI. Dr Berkowitz: So, once you're confident that this is a primary headache disorder - and presuming again (as in the example I gave to start us off here) that we're just a few weeks out from the initial trauma - and the patient's presenting to you for evaluation of their headache, how do you approach treatment in these patients? Dr Schwedt: Yeah, so the specificity of your question, I think, is actually quite important - so considering the timing of when you're seeing that patient really is essential. So, if we're a couple weeks out or a few weeks out and the person is still having symptoms, that tells us something to start. The majority of people who have postconcussion symptoms are going to have resolution within a few days, or a week or two, so if someone's still having symptoms at, let's say, two weeks, three weeks, four weeks, well, then that's an indicator that, unfortunately, they're likely to continue to have symptoms for some time - when we want to be a little more aggressive, if you will, with the diagnostics and management of that patient. So, like, very early on - let's say within the first few days, or even the first week or two - some patients won't require any treatment. So, if they're having mild headaches, and maybe they take something over the counter every once in a while as it gets a little more severe, that's oftentimes fine, actually. If someone's having much more severe problems with headache (even in that very acute setting), then maybe we would give them a prescription medicine just to take for their more severe headaches. But then as symptoms progress and persist, then we should of course be thinking about other ways to - in more of a preventive approach of how to - help the patient, because, unfortunately, we don't have high-quality evidence for how to treat both acute and persistent post-traumatic headaches. The recommendation for many years (and it continues to be) is that you determine the other headache type that the PTH most resembles and you treat it like that. For example, if someone has PTH and a lot of migraine symptoms, well, then you would treat it like migraine. That might mean actually giving people specific acute migraine medications. It might mean, perhaps, putting them on migraine-preventive medications. Certainly, using other forms of therapy besides medications - maybe physical therapy is needed if someone has a lot of muscular involvement of the neck. And if they're having vestibular dysfunction from the injury, maybe they need vestibular rehab. Cognitive behavioral therapies - there's some evidence, at least, to suggest that can be helpful after an injury - so, kind of the multimodal approach. We need to make sure that people are getting good sleep, or doing what we can for that to occur (we know that sleep problems, including insomnia, are quite common after a concussion, for example), and really making sure that we're treating the whole patient. The person who is still having headaches at multiple weeks after their injury - likely they're still having other symptoms, too (some of which I just named, but other symptoms as well), like symptoms of autonomic dysfunction are quite common (like orthostatic problems; autonomic type of orthostatic problems) after an injury, cognitive problems, emotional issues - people probably are anxious and not feeling well. A lot of these folks are quite healthy prior to their injury, and all of a sudden, they have, really, a significant problem, and maybe they're missing work and missing school, and so we really have to treat the patient as a whole, of course. Dr Berkowitz: Along those same lines, I was wondering - at this early stage - the patient has had still relatively recent head trauma (they are a few weeks out from this initial injury) but still having symptoms which, as you importantly highlighted, can go well beyond headache and a number of other neurologic symptoms they might have. Very common for the patient to ask, “How long is this going to last? How long am I going to feel like this?” How do you counsel patients? Obviously, the outcomes are very variable. How do you counsel patients as an expert here,  based on seeing so many of these patients a few weeks out - as you said, an otherwise healthy patient, minor head trauma, having headache, and potentially even other concussion symptoms as you mentioned - how do you counsel them on what to expect?  Dr Schwedt: I'll start by saying that this is an area of really high interest to me and my research team, as well as my clinical team - so we're not good enough yet in being able to actually predict recovery and the timing of that recovery - but this is an absolutely essential point, and for multiple reasons. The main reason is based on the question you just asked. Of course, our patients want to know, “When am I going to get better? How long is it going to take? When can I get back to my normal life (whether that be work, or playing sports, or military, or other scenarios)?” – so, that's the most important reason. And it's important as well, because from the clinician's standpoint, if you know (or if you think you know) based on prediction that someone's highly likely to continue to have symptoms – well, again, that might help you make the decision about how (you know, I'll use the word aggressive) to be with their treatment and how closely to have them follow up, and this type of thing. It's also important for research. I already mentioned that, unfortunately, there really isn't decent quality evidence (for example, for what treatments to use for post-traumatic headache), and part of that reason for that is that there have been attempts at large clinical trials, and they've failed in a sense, and I think part of the reason for that is because there is, fortunately, such a high rate of natural resolution of symptoms that if you end up enrolling those patients into these prospective clinical trials, it makes it difficult to actually study any difference you might see between a treatment and your placebo. So, if we can have and develop good, clinically useful predictive models, that would really help in each of those domains. So what do I do now? I mean, basically, it's a little bit of a cop-out answer, but what I do is, I try to look at the trajectory that the patient has had thus far (and so, you know, this is all just logical and obvious), but if a patient is already having some degree of improvement - even if they still have symptoms, but they're having some improvement over those first three weeks - well, you would more or less consider the slope of that recovery to persist more or less at the same level. On the flip side, though, if someone's there and it's been multiple weeks - and they've just had absolutely no recovery and maybe they're even feeling worse - then I'm more concerned that this might be a longer-term issue. Dr Berkowitz: That's helpful to understand both your approach and the challenges in making a firm statement on counseling our patients and using (as has been a theme in many of your helpful responses today) just, sort of, the clinical trajectory and what information that patient's giving you to try to help with the prognosis (however ambiguous it may be) and just needing time to see how the patient does. Dr Schwedt: I might just add as well, though, that there are studies that have suggested there are certain risk factors for prolonged recovery from post-traumatic headache (and there's some limitations to these studies, so, really, validation is needed), but for post-traumatic headaches specifically, I mean, probably the biggest risk factor for persistence of the post-traumatic headache is having headaches prior to the injury. So, for example, people who have migraine before TBI that then are having an exacerbation or a new headache after the injury - unfortunately, they're less likely to have resolution during the acute phase. Other factors include the severity of the injury itself - so there are certain features of the injury that if, you know, it is seemingly more severe, maybe their likelihood for resolution in the acute phase is lower. And then there are multiple other factors that have been suggested as well, including the patient's own expectations for recovery, which I find to be quite an interesting one.  Dr Berkowitz: Yeah - very important points. So, let's say that, unfortunately, the patient does continue to have headache now several months out after the trauma; how do you approach these patients with respect to treatment? Dr Schwedt: Yeah. Once someone's gotten to that point, they probably really are going to need more in the way of preventive measures (and, you know, I did mention some of these). So, if someone's having migraine-like PTH, well, then I'm probably going to end up putting them on medicines that I would use for prevention of migraine. You know, you do have to be especially careful, though, in these individuals who have had TBIs, because you want to make sure that the treatments you're starting aren't going to actually exacerbate their other symptoms, right? So, of course we know some of our migraine preventives can cause things like hypotension, or, you know, cause things like insomnia or cognitive problems, as side effects, and if people are already having those issues from their TBI, then we could actually make them overall feel worse even if we make some progress for their headaches. So, you know of course, we're always careful when thinking about side effects from these medications, but especially so, perhaps, in the patient with a concussion who's having some of these symptoms anyway. And then again - just to highlight, it's not all about medication - that's one small aspect here (one important, but perhaps small, aspect here). So, really, trying to get at lifestyle measures that can be helpful - so, again, sleep, and trying to help people to moderate their stress levels, and making sure that they have an environment that's going to facilitate the recovery (meaning, if they're having a lot of light sensitivity and sound sensitivity and these types of things, you know, doing what we can to help these individuals to be in environments that will allow them to recover). Dr Berkowitz: Yeah, all very important points - medication being just one part of treatment for these patients, as you said. But to just ask another question about medication so our listeners can learn from your expertise - I'm a general neurologist, and my experience with patients with post-traumatic headache and migraine and otherwise is that it's hard to predict who will respond to which medication (and some patients who failed many pharmaceutical medications will have an amazing response to riboflavin and vice versa) - in your experience (acknowledging that we are very limited in terms of data here), are there any migraine prophylactic agents that you feel, anecdotally, have been particularly helpful in patients with post-traumatic headaches or similar to the general migraine/tension headache population? It's very hard to predict, and it's trial and error and picking the right medication and finding the right dose (just depends on the patient). It requires the patient's patience - and our patience as well - as we sort of go through some trial and error. Dr Schwedt: Yeah, I guess. You can hardly even imagine how much I want to answer this question by saying, "Yes, with my experience, I've found that it's these two classes of medications that really work the best for folks with acute or persistent post-traumatic headache,” - but that would be disingenuous. It's so much like it is in migraine, where there is some trial and error, and, you know, again, as you say, it's so difficult to predict exactly which one is going to be the right pharmacologic agent for which patient. If access was no issue, I would go to medications that have the least side effects (which tend to be some of the newer medicines that we have for migraine), but we all know the realities of practice, and oftentimes, that's not a possibility due to access issues. Almost all of our patients that have significant postconcussion symptoms are also being managed by our neuropsychologists - and so, again, they're getting things like cognitive behavioral therapy and getting things like cognitive rehab, and they also are very helpful when it comes to workplace or school-place recommendations and accommodations. Many of our patients are being seen by our vestibular audiologists, as well, to work on their vestibular dysfunction, and vestibular rehab with physical therapy and occupational therapy. And so, you know, as you say, once you get out to multiple months, this is really a multidisciplinary, comprehensive type of treatment approach.  Dr Berkowitz: Let's say the patient has now gone one to two years out from their initial injury and you had started them on a prophylactic agent (or found the one that works for them maybe after a few trials), and they're doing great (no headaches for several months; otherwise young, healthy person), and they ask you, “Well, do you think I can just go ahead and try coming off these medications now? My injury is a long time ago. While those first few months were awful - thank you for helping me to get these headaches under control - do you think if I go off this medicine, that my headaches will come back, or am I sort of in the clear now?” How do you think about tapering patients off of preventive medications when they've had a good response at a year or so out? Dr Schwedt: That's so important, right? I mean, I think we all see patients that we inherit that end up kind of being left on medications that perhaps aren't even needed anymore, and it's certainly a mistake we wouldn't want to make. Post-traumatic headache - unlike primary headaches like migraine that tend to be present for decades - they can go away; they can resolve, and they usually do. I mean, we can't lose sight of that, right? Usually, it's going to go away on its own (as I mentioned, you know, within the first few days or weeks), and even after it's become persistent, if you can get a good treatment response, then, absolutely, after several months of that good treatment response, we should be tapering people off. Just like with any headache patient who's on a preventive, I would recommend tapering off of the effective treatment slowly, so if that's a medication, I'm usually very slowly just reducing the dose over several weeks or months (depends on how long they've been on it), usually not because I'm concerned about side effects of withdrawing the medication, but you're just testing it to make sure that the headaches aren't starting to creep back as you reduce the dose of that medication. So, it's a test, and if headaches do start to come back as you're lowering the dose, well, then, presumably you can more quickly get control of it again by elevating the dose back to where it was previously effective. For medications and treatments that don't really have dosing, the other way of doing it - so, you know, some of our medicines, of course, are given at one dose but given at intervals (like, let's say, each month or every three months) where you can't really reduce the dose - you can increase the interval between treatments. So, if you're supposed to have a treatment every month, well, if someone's doing really well, then maybe you say, “You know what? Give it an extra week.” Maybe do it in five weeks instead of four or six weeks. In that same way, you're kind of testing whether or not the medication is still really needed. Dr Berkowitz: Yeah, that makes sense as an approach here. In addition to your clinical expertise, Dr Schwedt, you're also a researcher in this area. Tell us, what's on the horizon for the future of diagnosis and treatment of patients with post-traumatic headache?  Dr Schwedt: There's a lot of exciting things on the horizon. It's really encouraging that despite, for example, the lack of evidence currently that we have for treatment, and perhaps not as much preclinical and clinical research into post-traumatic headache as we need, the exciting part is that there's a lot going on. Fortunately, the funding environment for such research has been decent over the past so many years, and so, again, there's almost certainly going to be meaningful breakthroughs here in the near future. Some of our own work - for example, we do a lot of neuroimaging research of post-traumatic headache. One of the main areas of controversy in the headache field is whether or not post-traumatic headache and migraine are really the same thing or are they truly distinct headache disorders? And so, like, a lot of our work has gone towards addressing that - both through neuroimaging, as well as just examining outcomes and symptoms and whatnot - to see where there are similarities and differences. And I'm absolutely biased when it comes to addressing this, but I feel strongly that they really are distinct headache disorders. And that's important, because that means that we need to continue to study them as distinct disorders and we can't just fall back to the idea of saying, “Well, PTH of a migraine phenotype is migraine, and we already have migraine therapy, so let's just use those,” because I think all of us that see patients with PTH in clinical practice realize that our migraine treatments don't work as well for PTH as they do for migraine. So, we really need to continue down the path of understanding the mechanisms underlying PTH, the mechanisms of what makes PTH persist (you know, why it persists in some people and not others), and then what we can do to intervene. I think a major topic, I believe, in determining best treatment approaches is also kind of related to the way you were asking me these questions - it's related to the timing of the intervention. Much of what's been done in studying treatment of PTH is done after it's already persistent, and so in some of these studies, including ours (I mean, it's not a criticism; including ours) - sometimes, these people have had post-traumatic headache for five years or ten years at the time that you enroll them into a study. And, you know, at that point, that's probably a very different population as far as mechanisms and who might respond to which treatments (compared to if you were studying those folks, let's say, in the first few weeks or in the first couple months). There's preclinical evidence (from rodent models of mild traumatic brain injury and post-traumatic headache) that the earlier you intervene, the more effective that intervention is going to be in treating that headache and preventing its persistence, and I would think we could logically presume that's probably the case in people as well. But, of course, we don't want to expose everybody early on to treatments if they don't need it (I mean, if they're going to have natural resolution, then that would actually be inappropriate [to expose them to treatments]). And that's where the prediction comes in. If we had good predictive models of - oh, you know, even though they're only a week into their headache, based on their pre-TBI factors and other characteristics, that they're very likely to have persistence - well, maybe that's the patient where they should have an earlier intervention, and, you know, in another patient, maybe not.  Dr Berkowitz: It's great to hear about your work and the work of others to help us understand this very, very common condition (and that's been a theme in many of our questions), one in which we do our best, but are often limited by, our scientific understanding and the data on how to best manage these patients' headaches. I've learned a lot from our discussion - both clinically, and I'm excited to have learned more about your work and what's on the horizon to help us take care of these patients.

Migraine is a neurological disorder affecting one out of ten Americans of all ages. This debilitating condition is responsible for an estimated 157-million lost workdays each year. What is migraine and how is it different from other kinds of headaches? On this episode of Baptist Healthtalk, host Dr. Jonathan Fialkow welcomes neurologist Brad Herskowitz, M.D., of Miami Neuroscience Institute to discuss diagnosing headache disorders and the latest treatments available to provide relief to those who suffer with them.

During this episode I have a discussion around some of the most common types of headache. Headache is very prevalent and can happen for a multitude of reasons. What's important is understanding the headache type and what treatments may benefit a particular presentation. Are you a headache sufferer? If so, what has helped you overcome them? *Episode Resource* The International Classification of Headache Disorders 3rd Edition (2018) Cephalgia. 38, 1, 1-211.

Shownotes Jeff: Welcome back to EMplify, the podcast corollary to EB Medicine’s Emergency Medicine Practice. I’m Jeff Nusbaum, and I’m back with my co-host, Nachi Gupta. This month, we’re tackling an incredibly important topic - evaluation and management of life threatening headaches in the Emergency Department. Nachi: Fear not, this will not simply be “who needs a head CT episode”; we’ll cover much more than that. Listen closely as this is an important topic, with huge consequences for mismanagement. Jeff: Absolutely. As some quick background - headaches account for 3% of all ED visits in the US, with 90% being benign primary headaches and less than 10% being secondary to other causes like vascular, infectious, or traumatic etiologies. It’s within these later 10% that we are looking for the red flag signs to identify the potentially life-threatening headaches. Nachi: And to do so, Dr. David Zodda and Dr. Amit Gupta, PD and APD at Hackensack University Medical and Trauma Center, and their colleague Dr. Gabrielle Procopio, a PharmD, have done a fantastic job parsing through the literature, which included over 500 abstracts, 89 full text articles, guidelines from ACEP and the American Academy of Neurology, as well as canadian and european neurology guidelines, to summarize the best evidence based recommendations for you all. Jeff: We would be remiss to not also mention Dr. Mert Erogul of Maimonides Medical Center and Dr. Steven Godwin, Chair of Emergency Medicine at the University of Florida College of Medicine. Nachi: Alright, so let’s get started with some definitions and pathophysiology. The international classification of headache disorders 3, or ICHD-3, classifies headaches into primary, secondary, and cranial neuropathies. Jeff: Primary headache disorders include migraine, tension, and cluster headaches. Secondary headaches include those secondary to vascular disorders, traumatic disorders, and disorders in hemostasis. These are the potentially life threatening headaches that can have a mortality has high as 50%. Nachi: And the final category includes cranial neuropathies, such as trigeminal neuralgia. Jeff: And I think we can safely say that that wraps up our discussion in this episode on cranial neuropathies, moving on…. Nachi: Headaches result from traction to or irritation of the meninges and blood vessels, which are the only innervated central nervous system structures. Activation of specific nerve ganglion complexes by neuropeptides like -- substance P and calcitonin gene-related peptide -- are thought to contribute to head pain. Jeff: It is important to note that all headache pain shares common pain pathways, thus response to pain medications does not exclude potential life threatening secondary causes of headache. This led to the ACEP guideline which states just that.. Nachi: I feel like that deserves ding sound as it's a critically important point. To repeat, just because a pain medication relieves a headache, that does not exclude dangerous secondary causes! Jeff: And what are the life threatening headaches? Life-threatening headaches include subarachnoid hemorrhage, cervical Artery Dissection, which includes both vertebral Artery Dissection and carotid artery dissection, cerebral Venous Thrombosis, idiopathic intracranial hypertension, giant cell arteritis, and posterior reversible encephalopathy syndrome, or PRES. Nachi: Slow down for a second and let’s not skip over your favorite section.. Let’s talk pre hospital care for headache patients. Jeff: Good call! Pre-hospital care is fairly straightforward and includes a primary survey, conducting a focused neurologic exam, and assessing for red flag signs, which include focal neurologic deficits, sudden onset headache, new headache in those over 50, neck pain or stiffness, changes in visual Acuity, fever or immunocompromised State, history of malignancy, pregnancy or postpartum status, syncope, and seizure. That’s quite a list. For a visual reference, see Table 3 in the print issue. Nachi: And patients with neurologic deficits or severe sudden-onset headaches, should be transported immediately to the nearest available stroke center. Tylenol should be offered for pain management. Avoid opioids and nsaids. Jeff: Upon arrival to the emergency department, history and physical should include your standard vitals, testing neurologic function, cranial nerve testing, head and neck exam, as well as a fundoscopic exam. As was the case for your pre-hospital colleagues, you should also assess for red flag signs for life-threatening headaches. Check out tables 2, 3, and 4 for more details here. Nachi: With respect to Vital Signs, in the setting of an acute headache, severe hypertension should prompt a search for signs of end-organ damage such as hypertensive encephalopathy, intracranial Hemorrhage, PRES, and preeclampsia in pregnant women. Additionally, fever, and especially fever and neck stiffness, should raise concern for CNS infection. Jeff: For your neurologic examination, make sure to include assessments of motor strength, coordination, reflexes, sensory function, and gait. Don't forget that lesions involving the anterior circulation, such as dysarthria, cognitive impairment, and Horner syndrome may be indicative of a carotid artery dissection, whereas dizziness, vision changes, and limb weakness may be due to a vertebral Artery Dissection. Nachi: And for cranial nerve testing - pay particular attention to cranial nerves 2, 3 and 6. For cranial nerve 2 - look out for an afferent pupillary defect, or a marcus-gunn pupil, which is seen in optic neuritis, giant cell artertitis, and central retinal artery occlusion. For CN3, oculomotor nerve palsies raise concern for a posterior communicating aneurysm and SAH. And lastly, CN6 palsies, which often presents with diplopia on lateral gaze , are often seen with intracranial idiopathic hypertension and cerebral venous thrombosis, in addition to impaired visual acuity, visual field defects, and tunnel vision. Jeff: For the head and neck exam, remember that a partial horner syndrome, with miosis and ptosis without anhidrosis, may be indicative of a cervical artery dissection. Unfortunately, if the patient presents acutely, their only complaint may be pain, as the neurologic sequelae may take days to develop. Nachi: Additionally, with respect to the head and neck exam, evaluate the patient for tenderness and beading along the temporal artery. Jeff: One review noted that temporal artery beading actually had the highest likelihood ratio for GCA, 4.6, whereas temporal artery tenderness only had a LR of 2.6 Nachi: And the last physical exam maneuver you should ideally perform is a fundoscopic exam for papilledema, which is often seen in IIH, malignant hypertension, and CVT. Jeff: Perfect so that rounds out the physical, next we have diagnostic studies. Most importantly, routine lab testing is typically of low utility in aiding in the diagnosis of headache. Nachi: Even ESR and CRP in the setting of possible giant cell arteritis have poor sensitivity and specificity to diagnose it. So even if the ESR and CRP are negative, if the suspicion for GCA is high enough, it should be treated and you should get a biopsy. Jeff: Do consider adding on a venous or arterial carboxyhemoglobin in the right clinical scenario, as CO poisoning represents an important cause of headache you wouldn’t want to miss. This is especially important at this time of year when heating systems are working overtime here in the states. Nachi: And hopefully you have a co-oximeter, so you can even check this non-invasively. Jeff: Interestingly, there may be a unique role for a d-dimer here as well. Several small studies have used the d-dimer to risk stratify patients with possible CVT. In one study a d-dimer level < 500 mcg/L had a 97% sensitivity and a negative predictive value of 99% - not bad! Nachi: Pretty impressive performance characteristics. I think that about wraps up lab work. Let’s talk radiology. Jeff: Though low yield, CT utilization is estimated at 2.5-10% of non-traumatic headaches. A non-con CT should be reserved for those with suspicion for an intracranial hemorrhage, while a contrast CT would be required in those in whom there is concern for an infectious process or space occupying lesion. Nachi: CT angio or MRI should be used in cases of possible cervical artery dissection. MRI also is the neuroimaging of choice for PRES, which is more sensitive for cerebral edema than CT. Jeff: Similarly, MRV is recommended in those with a concerning story for CVT. Nachi: To help guide your emergent neuroimaging utilization, ACEP suggests imaging in those with headache and an abnormal finding on neuro exam, those with new and sudden-onset severe headache, HIV positive patients with new headache, and those over 50 with a new headache. Jeff: With that in mind, let’s dive a bit deeper into the use of CT for SAH, a topic which doesn’t get a ding sound, but is certainly critically important. Recent literature have found that a CT within 6 hours of symptom onset has a sensitivity and specificity and negative predictive value of 100%. In addition, one 2016 study demonstrated a LR of 0.01 in those with a negative HCT within 6 hours. These are really important results because that means SAH is essentially ruled out with a negative study. Nachi: Unfortunately, the 2008 ACEP guideline and 2012 AHA guidelines still recommend a lumbar puncture in those being worked up for SAH. Luckily the ACEP guideline is currently being revised so your decision to forego the LP with a negative HCT in the first 6 hours will likely also be backed by ACEP in the near future. Jeff: That’s a nice transition into our next test - the LP. Since LP carries a risk of herniation, in those with signs of increased ICP, make sure to get appropriate neuroimaging before attempting the puncture. In those without signs of increased ICP, no imaging is necessary. Nachi: While the position in which the LP is performed doesn’t matter as much when ruling out infection or SAH, in those with suspected IIH, make sure to obtain an opening pressure with the patient lying in the lateral decubitus position. An opening pressure of greater than 25 is often seen in IIH. Jeff: And the LP in the setting of IIH is not only diagnostic but also potentially therapeutic, as the removal of 1 ml of CSF can lower the pressure by 1 cm of H20 and potentially relieve the patient’s symptoms. Nachi: Always rewarding to diagnose and treat simultaneously... Jeff: Absolutely. But back to the LP for SAH for a second or two. When evaluating for a subarachnoid hemorrhage, you’ll often note an opening pressure of greater than 20 with persistent RBC in all tubes. Nachi: While there are no RBC cutoffs, one study found no patients with a SAH with less than 100 RBC in the final tube. In contrast, greater than 10,000 RBC increased the odds by a factor of 6. In addition, one 2015 study found that patients without xanthrochromia and less than 2000 RBC were effectively ruled out of having a SAH with a combined sensitivity of 100% Jeff: Lots of 100% sensitivities and specificities being thrown around today, which is definitely not the norm. No complaints here, I’ll take it. Anyway, the last test to discuss is our good friend the ultrasound, specifically the ocular ultrasound. Nachi: Examining the optic nerve sheath 3 mm posterior to the globe, an optic nerve sheath diameter of 5 mm or greater is predictive of an ICP greater than 20. Jeff: Keep in mind that this may expedite the work up, though a normal diameter does not rule out increased ICP, so a head CT may still be indicated. Nachi: Alright, so we’ve talked a lot about testing, both lab and imaging, and we’ve mentioned a bunch of pathologies, but let’s spend a few minutes going over the specifics of each. Jeff: Let’s start with SAH. SAH account for 1% of all headache visits to the ED. Most nontraumatic SAH are caused by aneurysm rupture. A missed diagnosis of SAH can have a case-fatality rate as high as 50% Nachi: Although 75% of SAH patients report an abrupt onset, objective neck stiffness has the highest likelihood ratio of 6.6. Other important features include LOC, neurologic deficit, subjective neck stiffness, photophobia, and onset during exertion or intercourse. Jeff: Additionally, approximately 20% of patients with a SAH have warning signs of a sentinel bleed including headaches, cranial nerve palsies, neck pain, or nausea and vomiting. Nachi: In order to aid you in diagnosing a SAH, you should consider the ottawa SAH Rule which has a 100% sensitivity and a 15% specificity. To use this rule you must be between 15 and 40 with a GCS of 15 and present with a headache with maximal intensity within 1 hour of onset. If you meet those inclusion criteria, and you have no neurologic deficits, no neck pain or stiffness, no witnessed LOC, no onset during exertion, no limitation of neck flexion, and no thunderclap onset, you can essentially rule out a SAH. Jeff: While the ottawa SAH rule has been prospectively validated, know that this study has been challenged for its interobserver variability, but in any case it still provides helpful red flags to consider. If your patient is found to have a SAH, a CT angiogram and neurosurgical consultation should be considered immediately. Nachi: In addition to monitoring ABCs, early care involves the administration of analgesics and anti-emetics. Also consider elevating the head of the bed to 30 deg, which may also improve venous drainage and decrease ICP. Jeff: In terms of BP management, guidelines from the american stroke association recommend targeting a SBP of 160 with a titratable agent like nicardipine or clevidipine. Nachi: In addition, nimodipine, 60 mg q4h, should be given to those with aneurysmal SAH to improve outcomes. Jeff: and any role for anti-epileptics? Nachi: That’s controversial and the authors state it may be considered in the immediate post-hemorrhagic period and should be limited to a 3-7 day course with longer courses required in special populations. Jeff: The next pathology to discuss is cervical artery dissections, which account for 2% of all strokes and nearly 20% of strokes in those 50 and under. cervical artery dissections are most commonly due to trauma, but can occur spontaneously. Nachi: Risk factors include Ehlers-Danlos syndrome, osteogenesis imperfecta, and Marfan syndrome. Jeff: Regardless of the etiology, the management of cervical artery dissections is primarily medical with IV heparin followed by warfarin or a direct oral anticoagulant in those with extracranial dissections, and antiplatelet therapy like aspirin or clopidogrel in those with intracranial dissections. Nachi: Thanks to the CADISP study, we know there is no difference in mortality or neurologic outcome when choosing between antiplatelet therapy and anticoagulation. Jeff: Next we have cerebral venous thrombosis. This typically presents with a gradual onset headache. Though it can happen to anybody, cerebral venous thrombosis typically results from thrombotic disease. Nachi: Important risk factors include oral contraceptive use, pregnancy and postpartum states, Factor V Leiden deficiency, and lupus. Jeff: Treatment for CVT is controversial due to a high risk of hemorrhage and hemorrhagic transformation. According to the best available evidence, anticoagulation is the standard therapy with full dose anticoagulation of low-molecular weight heparin or heparin as a bridge to warfarin. Nachi: Yeah, it’s really a tough spot to be in as one third end up having some form of hemorrhage too…. Jeff: Perhaps yet another good place for shared decision making? Nachi: Honestly, it’s a good thought, but anticoagulation is the guideline recommendation, so I think that is likely the best route in this case. Jeff: Great point. Next we have idiopathic intracranial hypertension. This is typically associated with obese women of childbearing age. It may also be due to hypervitaminosis A from excessive dietary intake and even drugs like the retinoids used in treating dermatologic conditions and cancers. Nachi: idiopathic intracranial hypertension can be diagnosed by the modified dandy criteria which are found in table 8 on page 11. Let’s just run through the criteria. Jeff: The modified Dandy criteria for idiopathic intracranial hypertension include: signs and symptoms of increased ICP, no other neurologic abnormalities or altered level of consciousness, ICP > 20 on LP with normal CSF composition, neuroimaging without another etiology for intracranial hypertension, and lastly no other identified cause of intracranial hypertension. Nachi: And as we mentioned a few minutes ago, an LP can be both diagnostic and therapeutic, though the relief is likely temporary Jeff: For more permanent treatment, weight loss is the key. Acetazolamide, 250 mg to 500 BID is the first line pharmacotherapy. Combined with weight loss, acetazolamide and a low sodium diet has been shown to improve visual field function. Nachi: And if this fails, topiramate, furosemide, and in the worst case surgical options like CSF shunting, venous sinus stenting, and optic sheath fenestration are all options. Jeff: I imagine taking a diuretic for a headache could be a real hindrance on quality of life, though I suppose it’s better than risking vision loss or having a significant neurosurgery. Nachi: Agreed. Next we have giant cell arteritis. GCA is rare, with a prevalence of

Aim: To identify possible associations between muscular pain and headache in adolescents in a large population-based sample. Methods: Grammar school students were invited to fill in a questionnaire on headache and associated lifestyle factors. Headache was classified according to the German version of the International Classification of Headache Disorders (2nd edition). Muscular pain was assessed via denoting affected areas in schematic drawings of a body and via provoked muscular pain on controlled movements of head, neck and shoulder regions. Results: Prevalence of any headache within the previous 6 months exceeded 80%. In all subjects muscular pain or pain on movement was most prominent in the neck and shoulder region, ranging from 9% to 27% in the non-headache population to up to 63% for individuals with migraine or mixed migraine and tension-type headache (TTH). Frequency of muscular pain increased significantly with growing chronicity of TTH. Interpretation: A strong association between muscle pain in the neck/shoulder region and headache was observed, pointing to the importance of muscular pain for headache in adolescents. Also, in this age group muscular pain appears to be of particular importance in chronic TTH and – unexpectedly – in migraine, which is the most important new finding in our study.

Introduction: Stress is considered the major contributor to migraine and tension-type headache in adolescents. Previous studies have focused on general stressors, whereas the aim of the present study was to investigate associations between individuals’ stressful experiences and different types of headache. Methods: Adolescents from 10th and 11th grades of grammar schools filled in questionnaires. Stressful experiences were measured with the Trier Inventory of Chronic Stress. Type of headache was classified according to the International Classification of Headache Disorders. Linear regressions, adjusted for sex and grade, were calculated to estimate differences in stress scores that can be attributed to migraine, tension-type headache or miscellaneous headache. Results: A total of 1260 questionnaires were analysed. Tension-type headache, migraine and co-existing migraine plus tension-type headache were found in 48.7%, 10.2% and 19.8% of the participants. In subjects with migraine or co-existing migraine plus tension-type headache, high increases in stress scores were found in all investigated dimensions, whereas much weaker and inconsistent associations were found in subjects with tension-type headache only. Conclusions: The characteristic of migraine is more associated with stressful experiences than this is the case for tensiontype headache. This suggests that adolescent migraine patients might specially benefit from behavioural interventions regarding stress.
