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).
Although many people have only isolated panic attacks, others suffer from recurring attacks, which is a symptom of panic disorder. This disorder is fairly common; 2.7 percent of Americans 18 and up have it, which makes it more common than bipolar disorder, schizophrenia and obsessive compulsive disorder [source: NIMH]. Panic attacks can last anywhere from a few minutes to a half-hour, and they're gravely frightening and confusing for the victim. If left untreated, recurring episodes can lead to agoraphobia, where the fear of having an attack becomes so intense that the sufferer avoids all public places.
