The causes of anxiety disorder are unknown. Research indicates that areas of the brain that control the fear response may be involved. Anxiety disorder seems to run in families. This suggests that a combination of genetic and environmental factors may contribute to the development of the disorder. Brain chemistry is also being studied as a possible cause. Brain chemicals that may be involved include serotonin, dopamine, and norepinephrine. Anxiety disorder often occurs with other mental and physical conditions, such as substance abuse and depression. Many people try to ease the symptoms of anxiety with alcohol and other drugs. The relief these drugs may provide is temporary, however.
