The typical course of panic disorder begins in adolescence and peaks in early to mid-twenties, with symptoms rarely present in children under the age of 14 or in older adults over the age of 64 (Kessler et al., 2012). Caregivers can look for symptoms of panic attacks in adolescents, followed by notable changes in their behavior (e.g., avoiding experiencing strong physical sensations), to help potentially identify the onset of panic disorder. Panic disorder is most likely to develop between the ages of 20-24 years and although females are more likely to have panic disorder, there are no significant sex differences in how the disorder presents (McLean et al., 2011).
About 2-3% of Americans experience panic disorder in a given year and it is twice as common in women than in men. Panic disorder can interfere a lot with daily life, causing people to miss work, go to many doctor visits, and avoid situations where they fear they might experience a panic attack. The interference is greatest when people also have agoraphobia, as well as panic disorder.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
