Anxiety disorders are the most common mental illness in the United States. But despite their prevalence, they are still often misunderstood and therefore go undiagnosed and untreated. On this episode Jen Fisher talks with Dr. Judson Brewer, a renowned addiction psychiatrist and neuroscientist. Dr. Brewer is an associate professor at Brown University and executive medical director at Sharecare. His new book Unwinding Anxiety: New Science Shows How to Break the Cycles of Worry and Fear to Heal Your Mind is now a New York Times best seller.
