What are the five major types of anxiety disorders?
Anxiety disorders are a group of mental disorders characterized by significant feelings of anxiety and fear. The cause of anxiety disorders is a combination of genetic and environmental factors. Without treatment, anxiety disorders tend to remain. Generalized anxiety disorder GAD is a common disorder, characterized by long-lasting anxiety that is not focused on any one object or situation. Those suffering from generalized anxiety disorder experience non-specific persistent fear and worry, and become overly concerned with everyday matters. Generalized anxiety disorder is "characterized by chronic excessive worry accompanied by three or more of the following symptoms: restlessness, fatigue, concentration problems, irritability, muscle tension, and sleep disturbance". A diagnosis of GAD is made when a person has been excessively worried about an everyday problem for six months or more. In children GAD may be associated with headaches, restlessness, abdominal pain, and heart palpitations. The single largest category of anxiety disorders is that of specific phobias which includes all cases in which fear and anxiety are triggered by a specific stimulus or situation. Common phobias are flying, blood, water, highway driving, and tunnels.
