In this episode, Brian explains the distinction between primary and secondary headaches and breaks down the defining features of the "big three" primary headache types (migraine, cluster, and tension headache)—highlighting how often they are misdiagnosed and how they are treated. He explores the epidemiology of headaches, describing migraine as an invisible disease affecting about 12% of the population, disproportionately affecting women, while cluster headaches more often affect men. He discusses the major gap between demand for headache care and available specialists, and he offers advice on when to see a physician. Brian dives into the multifactorial nature and pathophysiology of migraine, including genetic and hormonal influences, neurovascular changes, and inflammatory signaling, and connects these mechanisms to modern therapies. Throughout the conversation, he emphasizes the individualized nature of headache disorders and the importance of a detailed headache diary. Brian shares practical strategies for treating headaches including lifestyle changes, medications, and neuromodulation devices.
