This article describes six common types of anxiety disorders: (1) generalized anxiety disorder; (2) panic disorder; (3) obsessive-compulsive disorder; (4) post-traumatic stress disorder; (5) specific phobias; and (6) social phobia. Treatment of anxiety disorders have two components that can be offered separately or in combination. They are medication and psychotherapy. Both approaches, alone or in combination, can be effective in most of the anxiety disorders, but specific phobias respond best to specific forms of psychotherapy where the person is gradually exposed to the feared object and learns to deal with the resulting distress.
