A Case of Seasonal Trichotillomania

J Clin Psychiatry 1997;58(5):218-219 [letter]

Letter to the Editor

Sir: We report the case of a patient who had both winter seasonal affective disorder (SAD)1 and trichotillomania with winter exacerbation, whom we treated with light therapy.

Case report: Ms. A, a 24-year-old woman, had a history of trichotillomania since 10 years of age. From the onset of symptoms, the trichotillomania persisted across the year, but improved in the summer, when she needed no special head covering, and worsened in winter, when she would habitually develop a bald spot 5 cm in diameter.
