Incidence of Panic disorder: About 1.7% of the adult U.S. population ages 18 to 54 - approximately 2.4 million Americans-has panic disorder in a given year. (Source: excerpt from Facts about Panic Disorder: NIMH).
Panic attacks usually begin abruptly and may reach a peak within 10 to 20 minutes but may continue for hours in some cases. Panic attacks are not dangerous and should not cause any physical harm. The effects of a panic attack vary. Some, notably first-time sufferers, may call for emergency services. Many who experience a panic attack, mostly for the first time, fear that they are having a heart attack or a nervous breakdown. Common psychological features associated with panic attacks include the fear of impending death or loss of sanity, and depersonalisation is relatively common.
