The trigeminal autonomic cephalalgias are a group of headache disorders that appear similar to each other and other headache disorders but have important differences. Proper diagnosis is crucial for proper treatment.  In this episode, Gordon Smith, MD, FAAN, speaks with Mark Burish, MD, PhD author of the article “Cluster Headache, SUNCT, and SUNA,” in the Continuum April 2024 Headache issue. Dr. Smith is a Continuum Audio interviewer and professor and chair of neurology at Kenneth and Dianne Wright Distinguished Chair in Clinical and Translational Research at Virginia Commonwealth University in Richmond, Virginia. Dr. Burish is an associate professor at UT Health Houston in Houston, Texas.

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 suc
