What is the main characteristic of a panic disorder?

The main characteristic of a panic disorder is episodes of intense fear or discomfort that peak within minutes. Individuals experiencing a panic attack typically report a sudden onset of intense anxiety accompanied by physical symptoms such as a racing heart, shortness of breath, dizziness, or feelings of impending doom. These panic attacks can occur unexpectedly or may be triggered by certain situations, but the hallmark feature is the overwhelming fear that escalates rapidly.

The other options do not capture the defining features of panic disorder. Persistent worry about daily activities is more characteristic of generalized anxiety disorder. Recurrent, unwanted thoughts are indicative of obsessive-compulsive disorder. Enduring patterns of behavior are typically associated with personality disorders. Focusing specifically on the acute, intense fear and physical symptoms during panic attacks helps distinguish panic disorder from these other anxiety-related conditions.
