Anxiety disorders refer to a range of psychiatric conditions, including phobias, panic disorder, obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD) and generalized anxiety disorder (GAD). According to the National Institute of Mental Health (NIMH), 40 million adults in the United States experience anxiety disorders every year. Generalized anxiety disorder can manifest in such symptoms as constant worrying, fatigue, restlessness and irritability. The Mayo Clinic says that some risk factors for GAD include genetics, being female, stress and personality. Fortunately, many prescription medications for GAD are available.
