BACKGROUND: Many investigators have reported that panic disorder (PD) patients with comorbid major depression (MD) have more severe symptoms and a poorer response to treatment than patients with PD alone. It is not known if this is due to a distinct and more serious underlying disorder in these patients or simply a result of the simultaneous presence of the two disorders.
METHOD: Nondepressed patients presenting for treatment of panic disorder with agoraphobia (PDA) were studied before treatment (N = 180) and after 4 weeks of treatment with adinazolam sustained release (N = 89) or placebo (N = 91). Twenty-nine percent (N = 53) of the patients had a past history of MD. Symptom severity and treatment outcome were compared in patients with primary, secondary, single, recurrent, or no past MD.
RESULTS: There were no consistent differences in symptom severity or treatment outcome in patients with a past history of primary, secondary, or single episode MD compared with patients with no history of MD. However, a small number of patients with history of recurrent MD exhibited consistently greater symptom severity and poorer response to treatment than patients with no history of MD.
CONCLUSION: The greater severity and worse outcome of comorbid PD and MD observed in earlier studies are more likely due to the simultaneous presence of the two disorders than to a more serious and enduring underlying disorder. However, our results suggest that recurrent MD may indicate a more serious condition in patients with PDA. This possibility warrants further study.
