Phenomenology and epidemiology of panic disorder

BACKGROUND: Panic disorder is a common and severe psychiatric disorder. The estimated current prevalence rate for panic disorder is 1% to 2% of the adult population. Panic disorder is commonly accompanied by major depression, substance use disorders, and other anxiety disorders. Female gender, low socioeconomic status, and anxious childhood temperament are common risk factors for panic disorder. Panic disorder can produce marked distress and impairment and is associated with significant suicide risk. Panic disorder appears to increase risk for all-cause mortality because it may increase risk for cardiovascular disease.
