Morbidity of comorbid psychiatric diagnoses in the clinical presentation of panic disorder.

This study seeks to determine how panic disorder patients with anxiety and depression comorbidity differ from panic disorder patients without comorbidity at the time of presentation for treatment. One-hundred seventy-one panic disorder patients presenting for their initial assessment and treatment at the Payne Whitney Anxiety Disorders Clinic agreed to participate and completed self-report and diagnostic assessments. Sixty-seven percent of panic disorder subjects were found to have at least one comorbid anxiety or depression diagnosis. Age and gender ratio were not affected by the presence of comorbid diagnoses. Comorbidity significantly contributed to psychological distress and symptom load, overall impairment, and interpersonal impairment.
