Insights are drawn from psychology, neuroscience, genetics, epidemiology, and clinical trials. Providing a fascinating illustration of the discussion are two interviews conducted specifically for the book, with the actor, writer, director, and television presenterMichael Palin and former England football manager Graham Taylor.The book covers in detail the six major anxiety disorders: phobias; panic disorder and agoraphobia; social anxiety; generalised anxiety disorder; obsessive compulsive disorder; and post-traumatic stress disorder.
