Panic disorder is a type of anxiety disorder in which you have repeated attacks of intense fear that something bad will occur when not expected.
See also: Generalized anxiety disorder
The cause is unknown. Genetics may play a role. Studies suggest that if one identical twin has panic disorder, the other twin will also develop the condition 40% of the time. However, panic disorder often occurs when there is no family history.
Panic disorder is twice as common in women as in men. Symptoms usually begin before age 25, but may occur in the mid 30s. Although panic disorder may occur in children, it is often not diagnosed until they are older.
