Anxiety disorders affect approximately 40 million American adults or 18% of the population in a given year. Anxiety disorders are categorized into subtypes: panic disorder, obsessive–compulsive disorder (OCD), posttraumatic stress disorder (PTSD), social phobia, specific phobia, and generalized anxiety disorder (GAD). Each anxiety disorder has different symptoms but all share a commonality of excessive dread and irrational fear. According to prevalence estimates, women are twice as likely as men to suffer from generalized anxiety, panic disorder, social phobias, and so on. Chapter 32 focuses on GAD.
