It's important to know the progression of muscle fiber dysfunction to better understand how to treat and how long it may take to correct the problem.   The analysis of current research provides substantial evidence supporting the progression of muscle fiber dysfunction as a significant contributor to musculoskeletal pain, aligning with the hypothesized sequence: sustained muscle tone leading to long-term muscle fiber shortening, which subsequently culminates in painful myofascial trigger points. The initial phase of this progression is rooted in the transition from normal physiological muscle tone to a state of pathological hypertonia or chronic muscle overload. Sustained low-level muscle contractions, even at submaximal levels, are shown to generate sufficient intramuscular pressure to compromise local capillary blood flow. This circulatory impairment leads to localized ischemia and hypoxia within the muscle fibers, precipitating a critical "energy crisis" due to insufficient ATP production. This energy deficit is pivotal for the subsequent development of muscle fiber shortening. ATP is indispensable not only for muscle contraction but also for the crucial process of muscle relaxation, specifically for the detachment of myosin heads from actin and the re-uptake of calcium ions. When ATP is depleted, these relaxation mechanisms fail, resulting in sarcomeres becoming locked in a state of sustained, pathological hypercontraction. This localized shortening at the sarcomere level forms the palpable "taut band" that is a hallmark of myofascial trigger points. Over extended periods, such sustained pathological shortening can also contribute to broader structural changes like muscle contractures, involving fibrosis and a permanent reduction in muscle length. The culmination of this progression is the development of painful trigger points. The sustained sarcomere hypercontraction, driven by the energy crisis and calcium dysregulation, creates a severely acidic local environment. This acidic milieu, coupled with tissue injury from prolonged ischemia, triggers the release and accumulation of various neuroactive and inflammatory mediators. These substances directly stimulate and sensitize muscle nociceptors, manifesting as the exquisite tenderness and characteristic referred pain associated with active myofascial trigger points. Furthermore, the pathophysiology of myofascial trigger points is characterized by a complex, self-perpetuating vicious cycle. The energy crisis and subsequent acidic environment inhibit acetylcholinesterase, leading to prolonged acetylcholine effects and further sustained muscle contraction. Concurrently, mediators like calcitonin gene-related peptide (CGRP) not only potentiate muscle contraction but also directly activate nociceptors. This intricate feedback loop ensures the chronicity of the condition, as the consequences of muscle shortening directly exacerbate the initial problem of sustained contraction and pain. This comprehensive understanding of the progression from sustained muscle tone to muscle shortening and painful trigger points has significant implications for both clinical practice and future research in musculoskeletal pain. For clinicians, it underscores the importance of early identification and intervention for chronic muscle tension and overuse, aiming to disrupt the energy crisis cycle before fixed structural changes or chronic pain states become entrenched. Therapeutic strategies should not only target pain relief but also address the underlying metabolic and biomechanical dysfunctions, including restoring proper muscle length, improving local circulation, and resolving the energy deficit. For researchers, the identified roles of specific molecules like CGRP and the intricate feedback loops within the "energy crisis" model present promising avenues for developing novel diagnostic markers and targeted pharmacological or rehabilitative interventions that can effectively break the self-perpetuating cycle of myofascial pain.   Online Courses: https://richardhazel.podia.com

Quelles traces laissent les intoxications alimentaires sur le cerveau ?

Imaginez. Un soir, vous goûtez un plat nouveau. Sur le moment, tout va bien. Puis, quelques heures plus tard, les premiers symptômes apparaissent : nausées, crampes, vomissements. Vous comprenez rapidement : intoxication alimentaire. Vous vous en souvenez longtemps, et surtout, vous ne touchez plus jamais à cet aliment. Ce réflexe de rejet, presque viscéral, n'a rien d'anodin. Il est désormais prouvé qu'il trouve sa source dans le cerveau.Le 2 avril 2025, une équipe de chercheurs de l'Institut des neurosciences de l'université de Princeton a publié une étude marquante dans la revue Nature. Leurs travaux montrent que les intoxications alimentaires peuvent laisser une empreinte durable dans le cerveau. Autrement dit, l'aversion que l'on développe après un épisode de ce type n'est pas seulement psychologique ou culturelle : elle repose sur des modifications neurobiologiques réelles.Pour le démontrer, les scientifiques ont mené une expérience sur des souris. Ils leur ont d'abord fait goûter une saveur sucrée inédite. Puis, une trentaine de minutes plus tard, les rongeurs recevaient une substance leur provoquant un malaise digestif. Résultat : les souris évitaient ensuite cette saveur avec constance, parfois pendant plusieurs semaines. Et ce, alors même que le cerveau est censé avoir du mal à relier deux événements séparés dans le temps.Ce qui a particulièrement frappé les chercheurs, c'est la région du cerveau impliquée dans ce mécanisme : l'amygdale. Connue pour son rôle central dans la gestion des émotions et des souvenirs traumatiques, elle est ici activée à la fois lors de la dégustation initiale, lors du malaise, puis lors du rappel du goût. Ce triptyque d'activation montre que le cerveau encode profondément l'expérience, et associe la saveur au danger.Plus encore, les chercheurs ont identifié les neurones chargés de transmettre le signal de malaise : ceux du tronc cérébral qui produisent une molécule appelée CGRP. En stimulant artificiellement ces neurones, ils ont pu recréer l'aversion sans provoquer de véritable intoxication. Preuve que le signal sensoriel seul suffit à conditionner le cerveau.Ces résultats vont bien au-delà de la simple aversion alimentaire. Ils montrent que le cerveau est capable, en une seule expérience, de créer un lien de cause à effet entre un goût et une douleur, même différée. Un mécanisme qui pourrait aussi expliquer certaines phobies ou réactions disproportionnées à des stimuli mineurs.Ainsi, une simple intoxication alimentaire peut laisser une trace, une mémoire enfouie, mais bien réelle. Une mémoire gravée dans les circuits émotionnels du cerveau, et qui guide nos comportements bien après la guérison. Hébergé par Acast. Visitez acast.com/privacy pour plus d'informations.

Autoren: "Im Blutsee" Vampire in Yucatans Höhlen – von Uwe KullnickForschung an Vampirfledermäusen ist nicht ungefährlich. Neben dem Wissensdurst des Menschen verbindet man mit Erkenntnissen über diese Tiere auch Vorteile für den Menschen.INFOWie Vampirfledermäuse Blut trinken, ohne krank zu werdenVampirfledermäuse bürsten sich gegenseitig auf, enthüllen komplexe soziale OrdnungFrühere Studien haben zwei wichtige gerinnungshemmende Verbindungen im Gift gewöhnlicher Vampirfledermäuse identifiziert: Toxine mit der Bezeichnung DSPA und das treffend als "Draculin" bezeichnete Toxin. Es ist wahrscheinlich, dass die Untersuchung der Tiere weitere faszinierende Verbindungen aufdecken wird."Diese Entdeckung ist ein weiteres Beispiel dafür, warum es so wichtig ist, die Natur auf breiter Basis zu schützen, da wir nicht vorhersagen können, woher die nächste grosse biologische Arzneimittelentdeckung kommen wird", sagte Fry. "Giftige Tiere sind auf der ganzen Welt bedroht, noch mehr als die meisten anderen bedrohten oder gefährdeten Arten, und zwar aufgrund vorsätzlicher Verfolgung aus Angst oder Missverständnissen.Während Vampirfledermäuse in der Populärkultur wegen ihrer blutsaugenden Tendenzen sehr verleumdet werden, hat ein internationales Team unter der Leitung von Forschern der Universität von Queensland (UQ), Australien, vor kurzem eine als vCGRP bekannte Verbindung in ihrem Gift identifiziert, die ihrer Meinung nach die Behandlung von Bluthochdruck und Herzinsuffizienz bis hin zu Nierenerkrankungen und Verbrennungen revolutionieren könnte.Laut Bryan Fry, einem der Forscher von UQ, handelt es sich bei der Verbindung um eine mutierte Form des Calcitonin Gene Related Peptide (CGRP) in unserem Körper - eine Verbindung, die die Blutgefäße entspannt. Peptide sind im Wesentlichen Substanzen, die aus Aminosäureketten bestehen und durch Amidbindungen miteinander verbunden sind."Die Peptide aus den Fledermäusen sind in ihrer Wirkungsweise ungewöhnlich selektiv, was sie noch therapeutisch nützlicher macht als das CGRP, da sie weniger Nebenwirkungen haben", sagte Fry in einer Erklärung. "Dies könnte Ärzten möglicherweise bei der Behandlung einer Reihe von Erkrankungen mit erhöhtem Druck in kleinen Blutgefässen helfen oder den Blutfluss zu beschädigtem oder transplantiertem Gewebe wie Hauttransplantationen verbessern.Bisher haben die Wissenschaftler an einem Standort in Mexiko Proben von Vampirfledermäusen gesammelt, die für ihre Forschung von entscheidender Bedeutung sind. Das Gebiet wurde jedoch vor kurzem von Drogenhändlern überrannt, was ihre Feldarbeit behindert.Quelle: NEWSWEEK ABONNEMENT-ANGEBOTE >Es gab zahlreiche Vorkommnisse, Gefahren und Erlebnisse  auf meinen viele Reisen.

Story at-a-glance Women with chronic migraines and body-wide pain were far more likely to have poor oral health, with over half falling into the lowest oral health categories in a new study Specific oral bacteria, including Mycoplasma salivarium and Gardnerella vaginalis, were significantly more common in women who reported frequent migraines and widespread pain Harmful oral microbes don't stay in your mouth; once gum tissue is inflamed, these bacteria enter your bloodstream, disrupt the immune system, and trigger systemic pain A less diverse oral microbiome was found in women with migraines and gut pain, making it easier for pain-triggering bacteria to dominate and inflame nerve pathways Inflammatory chemicals produced by oral bacteria — like calcitonin gene-related peptide (CGRP) and vascular endothelial growth factor (VEGF) — are directly involved in migraine and fibromyalgia, showing how poor oral hygiene can set off whole-body pain responses

In this episode, I review the pathological and clinical dimensions of migraine, the most common disabling neurological disorder. I tried to capture migraine's diverse disabling recurrent symptoms, from its risk factors, triggers and prodrome to the aura, the headache, and multiple heightened sensitivities.To illustrate the lived experience of migraine, its classical manifestations, and its curious variants, I refer to such vivid patient memoirs as those of Monica Nelson titled Mere Sense, and Abby Reed titled The Color of Pain. I also cited Oliver Sacks classical book titled 'Migraine'.I also flavour the podcast with historical migraine patient anecdotes, such as those of Ann Conway, the enlightenment writer who was treated by the great physicians William Harvey and Thomas Willis, of Annie, who was treated with an astounding number of therapies by the famous Queen Square neurologist William Gowers, and of Alexander Pope who treated his migraines in a most unconventional way.In this regard, I relied on Migraine: A History, Katherine Foxhall's magnificent historical account of the medieval ideas and treatments of the disorder, and Soul Made Flesh, Carl Zimmer's exhilarating biography of Thomas Willis.The podcast also explores and the evolution of migraine's acute and preventative treatments, and how a better understanding of its pathology is leading to treatments such as those that influence the CGRP pathway.

Prof. ssa Simona Sacco & Prof.ssa Enrica BonanniSapevate che più del 20% degli emicranici soffre di insonnia? Nei pazienti con emicrania cronica, la prevalenza può raggiungere anche il 60%.​ Con questa associazione l'emicrania è più grave e difficile da curare. Vediamo insieme quali domande fare al paziente per capire di che tipo di insonnia soffre soffermandoci anche sui sintomi diurni e quali esami programmare. Una volta identificata la problematica è  fondamentale impostare una terapia adeguata con  gestione personalizzata, basata sul tipo di insonnia identificato e sulla presentazione clinica del paziente. La promozione di una buona igiene del sonno è fondamentale. La terapia di prima linea raccomandata è la terapia cognitivo-comportamentale per l'insonnia (CBT-I). ​Abbiamo a disposizione ipnotici efficaci come i nuovi non benzodiazepinici o gli antagonisti duali per il recettore dell'orexina che si sono mostrati idonei nel trattare l'insonnia anche nel paziente con emicrania. La melatonina a lento rilascio e consigliata nei soggetti con più di 55 anni. Nella pratica clinica è possibile provare a migliorare il sonno notturno e contemporaneamente prevenire gli episodi di emicrania ricorrendo ad alcuni specifici farmaci. Dobbiamo essere consapevoli che curare l'insonnia riduce l'impatto complessivo della emicrania e migliora sensibilmente la qualità di vita del paziente. Vedremo infine l'ultima affascinante ipotesi sul meccanismo patologico alla base dell'associazione tra emicrania e insonnia che vede il coinvolgimento del sistema glinfatico che ha il compito di ripulire il cervello da tutte le sostanze di scarto. Il sistema glinfatico gioca un ruolo nella modulazione del dolore eliminando ad esempio il peptide correlato al gene della calcitonina (CGRP), un mediatore chiave nella fisiopatologia dell'emicrania. Il sistema glinfatico funziona soprattutto durante il sonno, e in particolare durante il sonno profondo non-REM. Con l'età si riduce sia il sonno profondo, sia l'efficienza del sistema glinfatico e viene compromesso il potere restaurativo del sonno. I farmaci in grado di aumentare questo tipo di sonno potrebbero quindi avere un ruolo anche nel controllo dell'emicrania.

Today, I'm interviewing Dr. Serena Orr on pediatric headache, which is part of the April 2024 Continuum issue on headache. Dr. Orr is an Assistant Professor at the University of Calgary, and a Pediatric Neurologist at Alberta Children's Hospital in Calgary, Alberta, Canada. Welcome to the podcast. So, thank you, Dr. Orr, for taking the time to speak with me about this fantastic article that covers such an important topic – headache in the pediatric population, in children and adolescents. First, I'd love to start by learning a little bit about you. Where do you practice, and how did you get interested in this topic? I love learning more about the authors of these incredible articles and how they became interested in their fields. So, you know, pediatric neurology is already a pretty subspecialized area of medicine – how did you become interested even further subspecializing in headache? Dr Orr: Well, thank you for the invitation. Nice to meet you, Dr. Weathers. I'm Serena Orr. I'm a clinician-scientist, pediatric neurologist, and headache specialist based in Canada at the Alberta Children's Hospital in Calgary, Alberta, just outside of the Rockies. I'm really passionate about headache medicine. I think I came to it because it allowed me to marry my interests in neurology and psychology together. I did my undergraduate studies at McGill in psychology and really wanted to take a biopsychosocial approach to my practice. The first child neurology patient I ever saw was a child who was experiencing migraine and having a lot of disability from it, with lots of impacts on her life - and I really saw an opportunity to take a holistic approach to the patient and marry my interests in neuroscience, neurology, and psychology together. So, I'm very excited to talk to you today about this topic that I'm really passionate about and that I think is underserved – um, hopefully get more people excited about it. Dr Weathers: But so great, and I'm sure we will do that just based on how excited I was just reading your article. So, I always like to start, actually, with what you feel is the most important clinical message of your article. What is your biggest takeaway you want to leave our listeners with? Dr Orr: Yeah, well I think this is a really big topic in neurology. So, if you look at the reasons for consulting a child neurologist, headache falls into the top three. 60% of youth experience headache in youth. If we look at what presents to neurology in terms of headache, the majority is migraine – and so that's a big focus of this article, because anywhere between a half to 88% of headache consultations in neurology are for migraine. And as I kind of alluded to in discussing my interests in this area, you know, it's really important to take a biopsychosocial approach to managing any chronic pain disorder, including migraine and headache disorders. Another big takeaway point from the article is that - specific to pediatric headache - there's really high placebo response rates that we're still trying to understand and grapple with in the field, and I think this underscores the importance in really doing patient-centered care and ensuring that you're educating patients and families about the level of evidence that we have about the placebo response rates and engaging in shared decision-making when you're choosing treatments together. So, I think those would be the main take-home points. Dr Weathers: I think both really critical. And I think even without – I'll put my plug in – even without the placebo effect, I think that shared decision-making is such an important concept for all of us in neurology to think about - but I think you make such the important point that with it, it becomes absolutely critical. I want to expand on a concept that you were just talking about. Pediatric headaches are so incredibly common, and you make the point in the article so well that they're one of the leading causes of neurological disability in pediatric patients. They have such a significant impact that really touches all aspects of these children's lives - both at school, how they impact their hobbies - pretty much everything that they do, and these long-reaching impacts. But then you go on to say that pediatric headache remains the most underfunded pediatric disease category when you take into account allocated public research dollars, which was just staggering to me. Why do you think this is? Dr Orr: I think there's a few reasons. So, one of the main reasons, I think, is that headache medicine has been underserved - there haven't been enough people who have gravitated to this field. I think this is rapidly changing as we train more people and show the world how important this topic is and how much exciting translational research is going on. But, historically, this has been a very small subspecialty that's been underserved relative to disease burden (so not enough scientists equals less research funding) - but there's another aspect to this as well. There was a paper published in 2020 by Mirin – who actually looked at research dollars in NIH based on disease burden and whether the diseases were male or female dominant - and found that there's a significant gender bias in research funding. Male-dominant diseases tend to be significantly overfunded relative to female-dominant diseases when you look at disease burden - and if you look at the female-dominant disease table, headache disorders and migraine are in the top three most underfunded disease categories amongst the underfunded female-dominant diseases. That data has been replicated looking at NIH dollars on the pediatric side as well. They didn't look at gender breakdown in the pediatric paper that was published a couple of years ago, but found, actually, that pediatric headache disorders are the most underfunded in terms of NIH research dollars to pediatric diseases – so, top underfunded relative to disease burden. So, yeah, being underserved as a field - and then, I think, gender bias has also played a significant role in what gets funded over time. Dr Weathers: Wow, that is hard to think about. And I think those are really insightful points and ones we really need to think about as we think about the bias in our research and our funding. Why is access to care and treatment for these children and adolescents so important? I know this seems like a super obvious one, but it feels like the answer is actually really much more complex. Dr Orr: Well, there's data to show that earlier diagnosis can lead to better long-term outcomes for youth with migraine - and this is really important, because if you look at the incidence curves for migraine, you see that at least a third, if not more, of incident cases occur before adulthood. We also know there's some GWAS data to show that youth-onset migraine has a higher genetic loading when looking at polygenic risk scores than adult-onset migraine, so people who have migraine onset in youth may be more genetically loaded (that may be important). And we also know that early access to diagnosis and treatment gives them a better long-term prognosis. We know that headache disorders and migraine are associated not only with long-term potential for disability on the physical side, but also increase the risk of psychiatric comorbidities developing over time, so there's really a huge opportunity in accessing a diagnosis and treatment early to improve long-term function - both on the medical side, but also potentially avert poor mental health outcomes - and also diagnose and treat a subset of people with the disease that may be more genetically loaded. We don't know if that impacts outcomes, but potentially, it does. So there's lots of reasons, I think, that we can get in there early and make a big impact – and even for those who it takes a while to find effective treatment for, really having access to education early so that they understand their disease and also ways that they can engage in self-management strategies, I think, is really empowering to the patient and really important (even if we're struggling to find the best medical therapy). Dr Weathers: You laid out a lot of really important reasons, and again, it goes back to the arguments made at the beginning about why it's so important to increase the funding so that this is no longer an area that's underserved, so that we are able to increase the access, and that everybody who needs this kind of care is able to get it. I want to shift a little bit and think about how we diagnose and work up patients who present with a headache. So as a neurologist - and also as a parent - one of the scariest considerations for me is figuring out if a headache is just a headache or if it's a sign of something else (you know, what we think of as a secondary headache disorder). What is your approach to distinguishing between the two? Dr Orr: We take a very clinical approach to diagnosis. We don't have specific biomarkers for different headache disorders, so we're still, you know, relying on a really detailed history and physical exam in order to sort out the diagnosis. As I discussed in the article, really the key first branch point (like you say) is, is this a primary headache disorder or a secondary headache disorder? There's some tools that we can use in practice to try to get at that, I think the most useful of which is the SNOOP tool - it's an acronym that goes over headache, red and orange flags. Every time I write an article where I discuss this, it's expanded to include more red or orange flags (it's in its probably third or fourth iteration now), but there's a nice table in the article that goes over some of these red and orange flags. It includes things like systemic feature (like headache, nuchal rigidity), if there's a history of cancer, if there's associated, you know, headache waking child up in the morning with vomiting - and a variety of features. I have to say the level of evidence for some of the features is relatively low, and our understanding of some of the red flags has changed over time. As one example, we used to think occipital headaches in youth were almost always associated with a secondary headache disorder, but now there's more emerging data to show that it's actually relatively common for youth with migraine to have an occipital location. So, really, using the tool is about kind of putting the whole picture together to try to risk stratify. In the majority of youth who present with recurrent headaches, who don't have any red or orange flags, and who have an unremarkable neurological examination without focal deficits, it typically is such that we don't have to do further investigation - but any red or orange flags (or a combination of them), any focal deficits on exam, would typically be where we would be considering neuroimaging. It's very unusual that we have an indication to do an EEG or large amounts of blood work in youth with headache, but it is context specific - for example, a case presenting with recurrent hemiplegia (you may have Todd's paralysis on the differential and you may want to do an EEG), or in a youth who also has GI symptoms (I picked up some youth with celiac disorder who have chronic headaches as well). So there are specific circumstances where blood work, EEG may be indicated (or obviously lumbar puncture in the case of suspected infection, et cetera), but for the most part, we're really relying on a very thorough history and physical exam to sort out our pretest probability of a secondary headache disorder and whether we need to do neuroimaging and further investigations. Dr Weathers: I think keeping in mind that systematic approach and really working through the algorithm is really reassuring and makes sense that, one, you won't miss something kind of worrisome, but on the other hand, that you're also not doing unnecessary testing, either. Along those lines, what do you think is the easiest mistake to make when treating children and adolescents with headache, and how do you avoid it? Dr Orr: I think the easiest mistake to make is undertreatment. Both for acute and preventive therapies, I often see undertreatment. I think families are often hesitant to give medication to their children, and so I have a lot of families say, “Oh, well, you know we typically wait the attacks out until they get more severe, we try to avoid medication, we use cold compresses, et cetera.” So, explaining to families that acute treatment (of course, we don't want to overuse it) and overusing simple analgesics (NSAIDS) more than three days a week can increase the risk of higher frequency of attacks and medication overuse headache - but undertreatment is a risk, too. And the way I like to explain it to families is in the scientific basis of pain chronification - so I'll say to families, “You know, we have these pain pathways in our brain. If we let them go off for long periods of time, they get stronger (and so that's where we want to get medication in quickly to try to shorten the exposure of the attacks). When you don't do that, those pain pathways may start out like a dirt road - and maybe then you have lots of long attacks, and then it gets paved, and then it becomes a highway.” I find it's a useful way to help families understand the concept of pain chronification and why we want them to treat attacks. The same thing goes for undertreatment on the preventive side. If you know a youth is having frequent attacks that are impacting their life and their ability to function, we really should be thinking about a daily preventive treatment, because we know that pill-based interventions will result in a significant reduction in headache frequency in at least two-thirds of youth - and again, allowing the youth to have frequent attacks contributes to that pain chronification (and explain it to families in a similar way to what I just explained for acute treatment) - but there can be a lot of hesitancy to engage with pill-based treatments, even though we know that they can be helpful. Dr Weathers: I think that's a really powerful point - and I think something we also, frankly, probably tend to do on the adult side as well – but, especially, I could see where there's even probably more hesitancy in children and adolescents (this concern that we're going to overtreat them and then end up inadequately treating, which leads to increased problems). And also goes back to the concept you were talking about earlier about the importance of shared decision-making and really engaging with the patient and their families in the discussion early on to help avoid that, as well to have everybody aware of the benefits and the side effects of all of the different options, I think is so critical. I was also really excited to see you (in the article) write about the importance of a trauma-informed care approach. This is an area I'm really passionate about in my work as a clinical informaticist and how we can leverage the electronic health record to support trauma-informed care and raising awareness of what a patient's triggers may be. Can you explain to our listeners who may not be knowledgeable about this approach what it means, and why you think that this might be applicable to children adolescents with headache? Dr Orr: Thanks for bringing that up. I think it's really important as well. We've done some work in my lab (and many others have as well) to show that there's a relationship between adverse childhood experiences and the development of headache disorders in youth and adults. By adverse childhood experiences, I mean exposure to highly stressful (like toxic stress) environments in early childhood, such as experiencing death of a parent, divorce, abuse, neglect. So, we know that adverse childhood experiences are associated with higher risk of developing migraine and headache disorders, and knowing that and how common these are amongst our patients - really think it's important to advocate for screening all children, adolescents coming in with recurrent headaches for adverse childhood experiences and exposure to trauma, because it really will impact not only how you interact with the patient, but also potentially what you will screen them for on the mental health side. And so providing trauma-informed care, I think - of course we want it to be targeted - but really taking this approach with all patients is actually a good way to think about it, because trauma is very common in our society, and some of the ways that we've measured trauma in the past (like some of the examples that I gave, divorce, death of a parent) are really narrow and don't encompass broader aspects of trauma (like systemic racism and other things that people are experiencing that haven't been adequately measured). So what trauma-informed care is - you know, there's a few core aspects, and one is screening all patients for trauma. The way I do that in clinic is just asking them if they've had any major stressful life events (and then I give a few examples), but there are standardized questionnaires that can be used for this as well. And then really trying to develop a nurturing rapport with the patient - an open listening strategy, asking open-ended questions, being empathic with patients and families - I know we all try to do this, anyway, but really focusing on that, especially in the context of trauma. And then thinking carefully about not only how you're talking to the patient, but how you're approaching them during the physical exam (so, for example, asking permission before touching the patient rather than just diving into the exam to be sensitive to that). And then also recognizing, like I said, that some of the ways that we've conceptualized trauma have been a little bit narrow, and that trauma may occur in context outside of what we traditionally think of. Dr Weathers: Again, I think that's so important and could be certainly much more broadly applied than even just to this one field, but thrilled to see that you're incorporating it into your work and your research (and again, it was discussed in the article) - and, absolutely, I think that the more that we incorporate it as well here, I think, that the better off for all of our patients and the improved care we provide. Moving on from that, I always like to end my interviews on a positive and hopeful note, and so I'd love to hear from you what you're most excited about in the field of pediatric headache. What breakthroughs do you think are coming, or what's giving you the most hope? Dr Orr: There's so much, there's so much exciting stuff going on in our field (and so, you know, I'll have to rein in myself in here), but one thing is there's been an explosion of novel treatment options on the adult migraine side in the last five to ten years, including agents targeted at the CGRP pathway, calcitonin gene-related peptide, some monoclonal antibodies, and receptor antagonists. There's been an explosion of neuromodulation options with now five devices that have various levels of FDA clearance for use in adults and/or youth with migraine. And there are, for most of these devices and novel drugs, either published studies or ongoing research into how they may be used in youth, so I'm hopeful that we will have more treatment options that are evidence based for youth going forward. This is in part due to the Pediatric Research Equity Act that came out a couple of decades ago now that has put requirements for pediatric studies when new drugs are approved by the FDA for adults - so I think that has had an impact, and I'm hopeful that we'll have an expanded treatment landscape in the years to come. There's also a lot of really exciting, more kind of fundamental research going on that I think will help us move the pediatric field forward more rapidly. In the past, we have really often borrowed from what the adult neurologists are doing for adults with headache disorders without really understanding some of the fundamental biological and psychosocial differences between headache disorders onset in youth versus adulthood, and so there is more and more research going on to understand the biology of migraine in youth and some of the risk factors at this age and some of the features that may make youth a little bit different, because it's very rare that youth are just little versions of adults for any disease or problem. And then, you know, I've seen a really large expansion in the number of trainees who are interested in headache medicine since I've entered this field (I've even got one of our residents who's going to do a headache fellowship, which is exciting), and seeing the growth and interest in headache medicine and the number of people being trained really gives me a lot of hope for the future, because there's so much work to be done in this area, and, really, that's where we're going to have the largest impact - is in mentoring and fostering the next generation of headache neurologists. So, there's lots of reasons to be excited, and I would say to the trainees listening that if you want an exciting career where there's lots of opportunity to make impact both clinically on your patients and in terms of educating the next generation and spearheading research initiatives, headache medicine is for you.

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.

Today, I'm interviewing Dr. Mark Burish on cluster headache, which is part of the April 2024 Continuum issue on headache. Dr Burish is an Associate Professor of Neurology at the University of Texas Health Science Center at Houston, which is located in Houston, Texas. Mark, thanks so much for joining me today on Continuum Audio. I was really excited to be asked to talk with you about this article. When I recertified from my boards the last time (and actually, it will be the last time I have to take the exam), I did the AAN course on all of neurology. And I'm a neuromuscular guy, right, and so I was actually kind of worried about the headache part because I thought, “How interesting could that be?” And I was blown away at how fascinating headache has become, and in particular, your topic (cluster, SUNCT, SUNA, the trigeminal autonomic cephalalgias) - such a great topic. But before we start talking about them, I'd love to just hear more about how you got interested in this area - both headache, this topic in particular. What's your story, Mark? Dr Burish: Well, thank you very much for having me. I'm honored to be part of this. I got into headache probably the way many people do; is, in residency, you figure out what you like, and your residency clinic tends to start collecting patients that you like (not that you're trading them with other residents, but you see certain patients). And mine (by the end of residency) had a lot of headache and pain patients into it. Then, I was very fortunate and had the opportunity to do some research as part of my career. I'm an MD-PhD, and I spend about half my time now doing research on cluster headaches, so I'm very fascinated by these types of diseases. Dr Smith: Can you tell us really briefly what you're working on in your research? Dr Burish: Cluster headache is such a poorly researched area. There's not a lot of people in it, so we do a little bit of everything: we have a clinical trial going; we do some basic science on the circadian mechanisms (cluster gets this very weird timing to it, where the headaches happen same time every day); and we do a little bit of starting to wade into the genetics. Dr Smith: Well, super exciting. I was actually blown away by the statistics on cluster (as common as multiple sclerosis), and the severity of pain I was amazed to learn is above that of childbirth (it was, like, between nine and ten out of ten, which is really crazy). And I'm worried that I missed these patients in my neuromuscular clinic. So, maybe we can begin by - just tell us what you think our listeners need to know. If they have to drop off right now, what message do they need to remember from our conversation? Dr Burish: I think there's two things. First of all, the first-line treatments for these headaches have not changed recently. For cluster headache, you still treat it with oxygen, the triptans (the faster triptans; not the oral ones, but the injectables and nasals), and you prevent them with verapamil. For SUNCT and SUNA, you use lamotrigine. So, those have not changed over time. There are some new treatments, which we'll talk about later. Then the second point is, there are four different types of headaches in this family and they all look very, very similar (one-sided pain, autonomic features, ipsilateral lacrimation, rhinorrhea - that type of thing). They differ in the treatments and how long they last. If you get them wrong (if you misdiagnose them), you're probably not going to give them correct treatment. Indomethacin works very well for two of them (the ones with hemicrania in the name, so not the ones we're going to discuss today). And then SUNCT, SUNA, and cluster headache - indomethacin does not work very well. So, it's important to distinguish them and get them right. Dr Smith: Maybe we can start there, Mark. I mean, I was kind of appalled to learn that the average delay in diagnosis is four to nine years in your article, and given the severity of pain and the impact it has on these patients, that's clearly a challenge. What's so hard about this? And do you have pearls on how we can recognize these patients? And how do you sort this out practically in clinic? Dr Burish: For cluster headache patients especially, it is a lot more common than we would think it is, but it still goes misdiagnosed, partly because most cluster headache patients are episodic. So, there's an episodic version where you get them every day for a few weeks and then they might go away for a year. So, I think what happens is that patients start to get into a cycle and they either get confused for sinusitis (because it happens in the spring), or they schedule a visit with a neurologist or somebody else, but the headaches are over by the time they see them, and they cancel the visit. So, I think they get misdiagnosed partly because it's either confused or they don't see doctors fast enough. I think a little bit more awareness of what this disease is and then, somehow, a mechanism to get these patients in a little bit more urgently is probably what's necessary. Dr Smith: Well, Mark, access is a real issue in neurology more broadly, and I'd love to talk to you about that in a moment, but I wonder if we could go back. You talked about how similar these are to one another, yet the treatments are different. How do you sort out the diagnosis when you're seeing a patient? Let's say you have someone who comes in who has episodic, unilateral, very severe pain and some of these autonomic features. What are the pearls for differentiating cluster, SUNCT, and SUNA from each other? Dr Burish: The big difference between all these different headaches is the timing. As a general rule, SUNCT and SUNA attacks last seconds (they're very similar to trigeminal neuralgia); paroxysmal hemicrania (that's one of the hemicrania ones, where indomethacin helps) - those attacks last minutes; cluster headache attacks last about an hour; and the hemicrania continua is constant (that's the other hemicrania one where indomethacin works). The other part is how often they happen. Again, SUNCT and SUNA - very similar to trigeminal neuralgia, may happen hundreds of times a day; paroxysmal hemicrania - dozens of times a day; cluster headache - maybe a handful of times; and then, hemicrania is constant. Based on how long the attacks are and how frequent the attacks are, you can generally separate them out. And if you're not sure, just try indomethacin. And then if it doesn't work, you're trying to distinguish between SUNCT and SUNA, which lasts seconds, and cluster headache, which lasts an hour, so fairly easy to distinguish those. Dr Smith: How long does it take to medicine to work in a patient with hemicrania continua or paroxysmal hemicrania? I'll remind our listeners - there's a separate article in the same issue of Continuum on that topic - but for our purposes, let's say you try that; how long do you need to try it? Dr Burish: Yeah, there's a great, another article about how much to give and how it works. It is generally pretty quick. I have noticed with most patients that the onset is twenty-four to forty-eight hours. And then, if you stop the medicine, the same thing - offset is kind of twenty-four to forty-eight hours. So, patients know pretty quick whether it's going to work. Dr Smith: Wow - that's awesome. One of the things I was interested in was so-called “secondary cluster.” So, you've seen your patient and let's say you've diagnosed them with cluster (primary cluster). Do you do additional testing? Do they need imaging or other laboratory workup? Dr Burish: Yeah. The differential for cluster (and cluster is the one that we know the most about; it is the most common of all the trigeminal autonomic cephalalgias) - it's a fascinating differential. If you don't know much about them, migraine is probably the most common. If you do know a lot about them, hemicrania continua and paroxysmal hemicrania are very common. But there's all these secondary headaches that can look identical to cluster headache; these pituitary hormone-secreting tumors (prolactinomas) - things like that. So, because all these other secondary causes can happen, they generally recommend everybody gets an MRI of the brain, with or without contrast. If that is normal and the patients continue to not respond to the medicines like you expect them to (verapamil doesn't work, oxygen doesn't work, and so forth), then you might do some additional testing for pituitary bloodwork. So, just kind of a panel of hormones, looking at blood vessels (because there are some cases that dissections or AVMs can cause cluster headaches). And then sometimes get imaging of the apex of the lung because there's some data that - with the Horner syndrome - that that might be relevant. Dr Smith: I'll refer our listeners to your article, just in general, because they really need to read it. It's fantastic. But your discussion about the neuroanatomy is really cool, and probably more than we want to get into right now, but the intersection of the neuroanatomy with therapeutics, and some of these other potential etiologies. So, one thing I was really amazed by (or appalled by, frankly) was the frequency with which these patients have suicidal ideation, given the severity of the pain and, I assume, the long time it often takes to get this sorted out. How do you handle that in clinic? Do you have conversations with people about this? How often do you appreciate it? And any words of wisdom for those of us who might encounter these patients? Dr Burish: Yeah. It's not hard to imagine why patients would be suicidal with this. When you have pain that is a ten out of ten - and patients who have also had childbirth and cluster, they consider childbirth more around a seven - so you can imagine how painful this is and what thoughts might be going through people's heads. It tends to be (in my personal experience and some emerging data) that they are suicidal during a cycle. So, for these episodic patients (most patients are episodic with cluster headache for a few weeks), they are suicidal during those weeks. And when the headaches go away, much less risk of suicide. So, during the cycle, I try to get my patients in as fast as possible, get the medications in as fast as possible, but basically just be there to let them know that we have options, and so that they consider me as their first option, rather than something darker. Dr Smith: How successful is first-line therapy in these patients and what's your success rate with your initial attempt at treatment? Dr Burish: On the acute side, the as-needed medicines (sumatriptan, oxygen) - if you give an injection (not the oral; that takes too long) - incredibly effective; for most patients, one or both of those will work. We usually prescribe both because the injections - usually you can't get that many (they can be quite expensive, realistically speaking). But also, just practically speaking, patients can have headaches up to eight times a day and you're not really supposed to be taking sumatriptan eight times a day, so we also give oxygen (but then again, oxygen is not very portable, so that's where the sumatriptan comes in). On the preventive side - not great. There's been some studies suggest maybe fifty percent is as good as any preventive is going to work for you, and that's not considering side effects and other things that patients might stop them. So, we do need to have a few different preventive options and you may have to go through a few different things. Chronic cluster headache (which is the more rare version, where patients have them year-round) is anecdotally much more refractory to treatment. Dr Smith: Can you talk a little bit about bridge therapy? You differentiate bridge from prophylactic therapy in your article. Dr Burish: Yeah. When you're approaching one of these patients - let's say they're completely naive to any medications - usually we will give them a couple of as-needed, acute medications (sumatriptan injections and oxygen). We'll give them a preventive like verapamil, but the verapamil takes a few weeks to kick in. So, the obvious question is, “What am I supposed to do in the meantime, while you're ramping it up and it's kicking in?” So, we use these short-term preventives, which we call bridge therapies or transitional therapies. These are short-acting preventives; they kick in quick, but you can't take them for very long. The most common by far is prednisone. Or an occipital nerve block with some sort of steroid (so, steroids in some sort of fashion). We will usually give them right at the beginning of a cycle (right at the beginning of a flare for chronic cluster headache patients) while we are uptitrating something like verapamil. Dr Smith: This may be a really silly question, but the next time I see one of these folks and I want to start oxygen, how do I do it? What are the logistics of giving someone oxygen for this, and how do patients navigate that, right? If you're having eight attacks a day during a cluster and you work as a nurse in the headache clinic, you probably have oxygen there. But you get where I'm going, right? - it's logistically challenging. How do you order it, and do you have words of wisdom to make it easier for patients to use? Dr Burish: There's a whole kind of system of oxygen, durable medical equipment - stuff that I've had to learn. To boil it down, there are basically two types of oxygen. There's a concentrator - kind of just a machine that takes room air and turns it into about ten percent oxygen - that is sometimes effective for patients. But sometimes ten liters per minute (which is the highest that can give) is not enough and you need fifteen liters per minute. In that case, you need an oxygen tank (the big metal cylinders that you see with a extra device on top called a regulator, that can crank it up to fifteen liters a minute. For both of these - fifteen liters a minute - you're going to need a mask. The nasal canula is just - it doesn't get up to fifteen; it's not going to be enough, so we give you this bag mask (the non-rebreather mask, or the bag hanging out below it). You really need high dose, pure oxygen for these things to work, so you have to write orders that say, “fifteen liters a minute, with regulator and non-rebreather mask.” Dr Smith: I'll refer our listeners to your Continuum article. I know a lot of our listeners use Continuum at point of care. And, of course, you can access it electronically, so there's really great pearls there. Another question for you: CGRP agents have really transformed migraine; what role do they play, if any, in management of these headaches (cluster, SUNCT, and SUNA)? Dr Burish: I think this is a fascinating emerging area of cluster headache research. One of the studies in the last three years came out that it was successful for episodic cluster headache, called galcanezumab, and it did not work for chronic cluster headache. Meanwhile, a couple other CGRP companies have tried them and they were unsuccessful, at least according to the data on ClinicalTrials.gov. And some other CGRP studies are still emerging. We know that both migraine and cluster headache work on the trigeminal system (I mean, this is a trigeminal autonomic cephalalgia - it's in the name) and CGRP is involved in the trigeminal system. That's probably where the commonality between migraine and cluster headache come from - they both work on the same pain system. But why all of them seem to work for migraine and only some of them – you know, some of these medicines work for cluster headache - is a fascinating thing. Does that mean that we don't have the dose right? Does that mean that we don't have the timing of these clinical trials right? Does that mean it's just not as effective? And there's other things that are involved in cluster headache - it's an interesting mechanism that we can start to explore. Dr Smith: I wanted to learn more about the circadian aspects of this - I found that really interesting, and you commented that you're interested in that in a research perspective. Can you describe that phenomena a little bit and just tell us what your thoughts are? Dr Burish: The interesting thing about cluster headaches, specifically, is that the headaches happen, for most patients, the exact same time every day – so, within an hour each day. So, my patient usually will say, “They're at two AM.” Across different time zones, every study that's been done - well, not every study, but many studies have been done - two AM is the most common time of day. But if you ask an individual patient, patient number one will say, “They happen every day at two AM; patient number two will say, “They happen every day at three in the afternoon.” I had a patient who was, I think, kind of getting fed up with all the questions I was asking about his headaches, and he said, “Dr Burish, it's three o'clock; if you want to wait until three fifteen, I'm going to get a headache - you can see what it's like.” That's how sure he was about when the headaches were going to happen. And other than maybe hypnic headache, there are a few other headaches that have that level of circadian predictability. So, it's just an odd, curious, unique thing to these headaches and we don't quite understand why yet. Dr Smith: So, I'm curious if the time of day patients get their headaches is in any way correlated with other aspects of sleep phenotype, right? There's broad variability in your sleep phase - the length of it, when it starts and ends. Is there any relationship, in your experience, between the time of day (two AM, ten PM) and other aspects of their sleep? Dr Burish: We haven't seen that, to my knowledge. People have looked, for example, at sleep studies while patients are having attacks. These attacks occur out of REM sleep, non-REM sleep - it doesn't seem to matter. Anecdotally, patients will say, “My cycle last year - I had headaches every day at two AM. But my cycle this year - I have headaches every day at five in the afternoon.” So, even a same patient who, theoretically, is not having big sleep changes over different years, has different timing of attacks. Dr Smith: Mark, what's the latest thing? What's most exciting in the field that you can tell our listeners about? Dr Burish: There are a lot of new treatments for cluster headache. There's the galcanezumab, which we discussed a little bit. There is a new dose for prednisone. We weren't sure how effective it was; now we're using kind of neuroimmunology-level doses of prednisone (100 milligrams daily; kind of titrating down from there). And then there's an occipital nerve stimulator for the chronic cluster headache patients. Since the last Continuum review on this topic, these three trials have been successful, and I think what gets lost is how impressive each one of these is in different ways. The prednisone study is impressive because you had to study that medicine (which we thought worked but didn't have a good clinical trial), and it's really hard to enroll patients in a placebo-controlled study where you already think it works. Another was done by a large pharmaceutical company. This is not an advertisement for or against, but these companies have rarely ventured into studying cluster headache until recently. The third study, the stimulator study, was a ten-year, multisite study involving surgeons and neurologists - just a monumental effort. It's because of these impressive studies that we now have data on how to treat the patient. Dr Smith: Just so interesting. I tell you what - I mean, if you told me twenty years ago I would be this interested in headache, I would have said, “You're crazy.” But now I see why our residents are so interested in it and why you are. This is fascinating. I could keep going for another hour or two asking you questions, Mark, but maybe we can pivot back to where we began. You told us your story about enriching your resident clinic - and for those residents listening, those are words of wisdom right there, my friend. But here's my question for you: we've already talked about access to care and how you manage access for these patients, but we have a huge access issue in neurology broadly and we desperately need more neurologists. As you're probably aware, there are some of our colleagues that don't think pain is neurology (I'm not one of them, but I know some of them and respect them otherwise). If there's an access issue for neurology, there's a access crisis for pain neurologists. And you don't just see headache, as I understand it; you see other patients with pain. So, I want to give you the last few minutes of our Continuum Audio episode to do your pitch, right? What do you have to say to the residents that are listening to us (or students) about why you find managing pain so rewarding and why they should consider this as a field? Dr Burish: Yes - I also did a fellowship in pain medicine, in addition to my headache research, so I see a little bit of both. For me, the patients are very appreciative because you are talking with them about what they are interested in. They are not interested in the change in the MRI between last time - I mean, they are interested in it, but not as much as, “I hurt today.” So, patients are more than happy - they're very grateful that you are addressing their primary concern, the thing that they're going home with that day that they're worried about. For me, seeing these patients has been very rewarding. From the research side. I think it's fascinating that there's just not enough research in this area - you can create your own niche; you can look into your own mechanisms - there's just not a lot of people in this field. And then, I think from a clinical side, other than the rewarding nature of it, there's a lot of options that we have. There's all of these neuropathic medications; there's all these different headache medications. If you want to wade into the procedural side of things (which I did with pain management), you can get into fluoro-guided procedures and spinal cord stimulators and all these different options that we have for these patients that help them, in addition to whatever they're going through. I have patients that then come back and say, “Well, by the way, I have these seizures; do you mind helping me kind of just go through my antiepileptics.” And they're generally well controlled and they consider me kind of a general neurologist for them. So, I've found it extremely rewarding and I wouldn't do anything different. Dr Smith: Well, that's really great information and I hope our resident listeners will take that to heart. Your article is truly amazing, Mark. I can't tell you how much I was impressed with it, and for our listeners - you gotta check it out. I've got a list of ten other things on my piece of paper here I could ask Mark about, but I think we're probably at time. So, Mark, thank you so much. Congratulations on an amazing article and really fascinating and exciting area of neurology. Dr Burish: Thank you. Thank you very much for having me.

Dr. Gelfand is a child neurologist at the University of California, San Francisco, where she is an associate professor of neurology, and she also happens to be Editor-in-Chief of the journal Headache. Dr Gelfand, welcome, and thank you for joining us today. Dr Gelfand: Thank you so much for having me. Dr Jones: Dr Gelfand, this issue is full of extremely helpful clinical descriptions and treatment strategies for headache disorders. With your perspective as the editor for this issue - and you've just read all these wonderful articles and edited these articles - what were you most surprised to learn? Dr Gelfand: I would say that the medication overuse headache article I think is where you'll find the most surprising content. This is an area in headache medicine that has been controversial. I think what we've got is new data - relatively new data, published in Neurology (in the Green Journal) in 2022 - the MOTS trial, showing that what we all thought was not necessarily true. In headache medicine, there was this mantra that, if somebody is overusing (too frequently using) a certain kind of headache acute medication, you've got to stop them; you've got to have them stop it completely before you can get them on a preventive treatment if you expect it to work. Turns out, in this trial, that's not the case. People were randomized to either stopping the overused acute medicine and starting a preventive versus continuing it and starting a new preventive, and they did equally well. I think that's really taught us that that dogma was not based in evidence (was not true), and what really matters is getting a patient started on an effective migraine preventive treatment. Dr Jones: Wow, that is really – that is kind of ground shaking, isn't it? That's going to change a lot of practices for a lot of neurologists out there. Do you think that's going to be well received, or has it been well received so far? Dr Gelfand: I think it has. I want it to get out there further, so I hope everybody will read in that chapter and really pick up on that piece. I think it's helpful for patients, too - that we don't necessarily need to disrupt what makes them feel like they're getting some acute, in-the-moment relief. We just need to make sure we're getting a good-quality migraine preventive therapy started. That's the most important thing. We don't necessarily need to ask them to change something about their acute treatment. Dr Jones: That's fantastic, and it certainly could make things a little more straightforward, I think for people who are helping patients manage this. To be honest with you, the term, “medication overuse” almost sounds like it's putting the onus on the patient a little bit. Dr Gelfand: It very much does sound that way. It is a very challenging term for a lot of reasons. And I agree with you that that's a problematic part of this whole terminology. Dr Jones: Well, just three minutes into the interview here and, Dr Gelfand, you've already changed people's practice. I think that's wonderful, and we'll look forward to reading that specific article in the issue. Again, from your view as a headache specialist and a leader in the field, what do you think the biggest debate or controversy is in headache medicine right now? Dr Gelfand: I think where we're really a little bit stuck in trying to figure out how to move forward is how to take care of patients who have continuous headache. It's not even really a fully defined term, but if you imagine a person who - they wake up, headache is present; it continues to be present throughout the entire day; they go to bed- it's still present; if they happen to wake up in the middle of the night to go to the bathroom, it's there then - it's just there all the time. It can be hard to imagine that situation is real - that somebody could have a headache that is continuously present for weeks, months - but this is true of some of our patients who have chronic migraine, our patients who have new, daily, persistent headache, certain other headache disorders. This entire group of patients who have continuous headache have historically been excluded from treatment trials, so our existing data don't necessarily generalize to how to treat their condition. And we need to change that, because this is a group that is arguably most in need of research, most in need of effective therapies. The question is how? Who exactly should be included in the inclusion criteria? And then, what are your outcome measures? Historically, in migraine treatment trials, we use headache days per month or migraine days per month. Days of headache per month may or may not be the right primary outcome measure for somebody who's starting from a point of continuous headache. Maybe more appropriate is, how many severe headache days you're having in a month, or how much disability you have from your headache disease. It's an area that's evolving and really does need to evolve, because this is a patient population that has been underserved in research thus far. Dr Jones: I learned that, I think, in reading one of the articles talking about continuous headache at onset – so, the headaches that are continuous from day one, which is, as I understand it, pretty uncommon. But really very little of the clinical trial data speak to how to care for those patients - is that right? Dr Gelfand: That is exactly right. And, epidemiologically, maybe not as common. But in a headache clinic, we certainly see patients who have had these headache disorders where it starts on one particular day, it becomes continuous within twenty-four hours of onset and has now been going for at least three months, and we would call that new, daily, persistent headache. Or equally commonly, people with chronic migraine where it ramped up over maybe a short to medium-long period to daily and continuous. And now they have been experiencing continuous headache for some number of months, if not longer. Dr Jones: This question may be a little bit of an unfair question. One of the challenges with headache is that, unlike some other areas of a diverse specialty of neurology, there aren't as many biomarkers as you might have for dealing with patients who have cerebral ischemia or neuromuscular disease. Do you find that that leads to more differences of opinion or more variability in diagnosis and management than you might see in other areas? Dr Gelfand: I'm so glad you asked that question. What I find that leads to is more stigma. Many of our patients are not believed, including by medical professionals who they've met before. People might think they are faking their symptoms, or that there's some sort of secondary gain, or this is something related to - they just don't know how to manage stress. This is a real problem for patients with migraine to be encountering so much stigma. As a headache medicine clinician, when I'm meeting a patient, oftentimes I need to make sure to acknowledge that, almost certainly, they've encountered that before. I need to reassure them that they're not going to be experiencing that in our headache clinic, and really try to undo some of that harm to be able to build trust that we're going to have a collaborative relationship moving forward - we're going to be a team; we're going to be determining the next steps in treatment together - and that I 100% believe them that the symptoms they are experiencing are real, are very challenging. Because migraine and other primary headache disorders are real neurologic diseases that can be quite severe. But because we have a paucity of biomarkers, it's hard for some people outside the field to recognize that. And that, I think, has been really difficult for patients historically. Dr Jones: So, a challenge for clinicians has become really more of a burden for patients. Dr Gelfand: Yes - well said. Dr Jones: Yeah. That's too bad, and maybe someday that will change, and probably can be approached from a couple of different directions, right? - from educating clinicians' perspective and also pursuing the science. This might be a related question, Dr Gelfand - what do you think the biggest misconception you've encountered in - I'm thinking mostly from the provider of the clinician community - what do you think the biggest misperception or misconception there is about patients who have headache and the management of those patients? Dr Gelfand: Well, I think it is tied in, in some way, to this notion that the patients are somehow causing their problem; that it's something about - well, I'm a child neurologist; I see adolescents and children – so, their parent is causing their problem because they're a helicopter mom or whatever it is, or they're just not managing stress in an appropriate way. I think that that is really an issue that patients are sort of handed from the medical community. Whereas if I step back and think about it, before 2018, no migraine-specific preventive therapies existed. We were borrowing from all other corners of medicine. We were borrowing from antihypertensives, antiseizure medicines, antidepressant medicines, but there was no actual migraine-specific therapy. Then came the monoclonal antibodies targeting CGRP (calcitonin gene-related peptide) - they're targeting either the ligand or the receptor. We now also have the oral forms that target the receptor, the gepants. So, we do have this one or two classes, depending on how you break that out, that are migraine-specific preventive therapies. But that's not enough for a complex disease like migraine - we need twenty of them. Look at epilepsy; there are probably twenty-plus antiseizure medicines, and yet, some patients still seize. Is that because they're anxious or stressed, or their mothers are too stressed? No - it's because some people have terrible epilepsy. And yet that same explanation has not been afforded to people with difficult migraine disease, that with just one class of migraine-specific preventive (or two, if you break out the monoclonals and the gepants) - that, somehow, they're supposed to have magically stopped with this treatment. That really doesn't make any sense. It's because we don't have enough effective therapies that they're still having difficult migraine - it's not because they're causing their disease. Dr Jones: Thank you - that's a great example. That is important to understand - that misconception about causation. And we may come back to causation here in a moment. It really doesn't make any sense that there are few specific, disease-modifying therapies for migraine, which affects tens of millions of people in the United States alone, right? Why is that? Why are there so few? Dr Gelfand: First of all, Dr Jones, I love it that you called it disease-modifying therapy, because that's how I think about it, too. The term, “preventive migraine therapy,” which is the more commonly used therapy, is not always really useful because - some people who have continuous headache will say, “Well, what are you trying to prevent? I've got headache all the time.” But this is really just treatments that are designed to dampen down disease activity in any form - how frequent, how long of duration, how intense - and I think it is really better conceptualized as disease-modifying therapy, so I love that you use that term. Why have there been so few? I think that it comes down to a paucity of research. Historically, NIH has underfunded migraine and other primary headache disorder research quite a bit, compared to how much disability those diseases cause in Americans each year. Hopefully, that will be getting better soon; I think there are some positive signs that that could be moving in a more positive direction. But I think, because migraine and other primary headache disorders are “invisible” illnesses - can't show you an x-ray with a broken bone; can't show you a lab readout with what your disease activity is; like you said, there's not a lot of biomarkers. Because of that, it's been hard for funders to really get behind it, and I think that's put us a little bit behind where we need to be. More research will lead to more therapies. Dr Jones: Let's hope so. It certainly is very common and affects, again, millions upon millions of people and leads to impaired quality of life and disability, as you point out. You are also the editor-in-chief of a leading journal in your field, Headache. I know many of our listeners who are neurologists and perhaps interested in editorial work as a career path might be curious - what led you to that, and how has it helped you as a clinician (being in that role)? Dr Gelfand: Yeah - I love being the editor of Headache. It's the journal of the American Headache Society. I think it's where the most interesting new science and work in headache medicine is coming out of. I have always found that reading helps me learn. If I want to learn about a topic, I need to read about it and I need to synthesize everything I read about. Being an editor makes that so accessible and fun. I really enjoy reading all of the articles that are coming in. It really helps me to think about everything I know, and thought I knew, in the field. And keeps my mind really questioning – do I really know that that's true or did I just think that's true? - and now this new data shows me that, actually, it's something else. And I really enjoy being challenged that way, on a daily basis, by new science that's coming in. So for anybody out there who has an interest in editing and playing an editorial role, I definitely encourage you to pursue that. There are programs - I know that the Green Journal has a resident and fellow section; that's where I started out, and I really had a wonderful experience in that. And then in our journal, in Headache, we have an assistant editor program for junior people - residents, fellows, postdocs - people who want to learn more about how to be an editor. I think that you learn so much about how to be a better writer, how to be a better scientist, how to communicate your findings in the most effective way. It's just invaluable and it's very fun. Dr Jones: It is kind of selfishly fun, isn't it? Dr Gelfand: Right, right. Dr Jones: Yeah, and it's important work, obviously - to put good information out into the world. At Continuum, we also have - on our editorial board, we have two residents and fellow positions, again, for that career development. I have to ask you a really hard question here, Dr Gelfand. You mentioned you read to learn; if you had to make a choice - electronic or print - what would it be? Dr Gelfand: Electronic. I know that many journals, including ours, are having to make some of these decisions right now. But I read my PDFs and I store them so that I can come back to them and search for them, and make sure, when I'm citing them, that they actually say what I thought they said because sometimes I need to look back at that. So, I am an electronic person. How about you? Dr Jones: I think I'm print. Dr Gelfand: Uh huh. Dr Jones: And I'm just sitting here thinking, there are so many people listening to this interview, and they're screaming at their device, saying, “Electronic is the answer,” or “Print is the answer.” Like you, we want to meet our subscribers where they are, and I think neurologists are very clear in their preferences. Let's just say we'll agree to disagree, and no one is right and no one is wrong – how about that? Dr Gelfand: Fair enough - I can respect that. Dr Jones: All right. I have one more question for you. This might sound like a strange question in an interview between two neurologists talking about headache - what can you tell us about chicken farming? Dr Gelfand: Well, I'd be delighted to tell you about chicken farming. As you know, because they were squawking earlier in our chat, I've got a little flock of chickens in our backyard and they are an absolute joy in my life. One thing I can tell you is that chickens respond to the photo period (how long the daylight is in a year). Now that it's November, it's the time of year when they don't get a lot of light, so they stop laying very much. I find that between Thanksgiving and about Valentine's Day, we actually start to need to buy eggs, which makes me very sad because I love having our egg supply come completely from our chickens. But we want them to rest and so that's what they're doing. Chickens will not lay very much at this time of year. During the summer and the spring and the fall (in the earlier part of the fall), they will lay almost daily, depending on which breed and how old they are. But at this time of year, it's really quiet - really, just one or two a week, I would say, right now. Dr Jones: It sounds like a fun hobby. Hopefully the chickens don't mind that you're buying chickens in the winter, and they don't feel offended by that or jealous. Dr. Gelfand: I worry that they do. I try not to show them the grocery bags. Dr Jones: Well, Dr Gelfand, thank you so much for joining us today, and thank you for such a thorough and fascinating discussion on headache disorders from your unique position as a guest editor for Continuum, I do encourage all of our listeners to check out that issue. It's really full of phenomenal pointers on practice-changing tips and tricks for managing patients who have headache disorders. I'm really grateful for your time today.

Mei Mei Hu, the CEO and Co-Founder of Vaxxinity, focuses on an approach to vaccines that aims to break immune tolerance to get the body to produce the antibodies to target self-antigens causing chronic conditions. Initial trials are being conducted to slow the progression or prevent the onset of Alzheimer's, Parkinson's, and hypercholesterolemia. Motivating this effort is the desire to democratize health and make transformative medicines available to a larger population at a lower cost.   Mei Mei explains, "Interestingly, in 1900, the average global life expectancy was 32. Today, when you hear someone died at 79, you're like, oh my gosh, what happened? We get these two bonus lifetimes now, and those three lives total for three main reasons. The first is the Green Revolution feeding us all. The second is hygienic plumbing, and the third is vaccines. But when we think of vaccines, they're usually crying babies or kids pre-COVID. What they did was able to banish the biggest diseases of our early lives." "What we're looking to do now at Vaxxinity is do the same thing but for the diseases plaguing us in our second and third lives. That's why we go after things like Alzheimer's, Parkinson's, hypercholesterolemia, which is a leading cause of heart disease. We're going after big population health things, and the best way to do them is with a vaccine approach." "One of the main attributes of a vaccine is that it trains your body to attack pathogens or causes of disease. In our case, we're just teaching your body to produce drugs that help neutralize things like cholesterol, plaques, or CGRP, which is the culprit of migraines.

Around 1 billion people around the world suffer from a mysterious neurological condition called migraine. Far more than just a headache, migraine is abnormal processing of the world around us that can have symptoms like loss of sight and speech, dizziness, nausea and extreme fatigue.There are drugs which can help those struggling with the condition like anti-depressants and anti-convulsants. However, they weren't developed specifically for migraine and can come with quite a lot of side effects or simply not work.For a long time migraine medication has been a process of trial and error. But a new class of drugs called anti-CGRPs are being hailed as a breakthrough migraine medication. Anti-CGRPs have a small side effect profile and were designed specifically to target migraine. They work by blocking CGRP (Calcitonin Gene-Related Peptide) from building up in the body and triggering a receptor in the brain which turns on a head pain pathway causing the migraine attack.Earlier this year the National Institute of Health and Care Excellence - or NICE – in England cleared the use of an anti-CGRP called Rimegepant to use as both a preventive and acute treatment. Clinicians are hoping this will massively improve the lives of those living with the condition.So this week on The Inquiry were asking ‘Have we reached a turning point with migraine medication?'Contributors: Dr. Amaal Starling, neurologist and headache specialist at Mayo Clinic in Scottsdale, in the US state of Arizona.
