Abstract

The authors surveyed 34 patients with obsessive-compulsive disorder for a history of seasonal variations in symptoms and behavior and treated six of these patients with bright light. Overall, the patients with obsessive-compulsive disorder did not report a greater degree of seasonal variations than normal and no response was seen to bright light therapy in the small number of patients treated.
