Abstract

Background Light therapy has been used to treat winter depression in bipolar disorder, although the dose, duration, and timing of treatment have differed. The present study is an open trial of light therapy for depressive episodes in autumn/winter using a Dutch protocol specific for patients with a bipolar disorder.

In total, 58 patients received light therapy for a minimum of 7 days and a maximum of 21 days; there was a follow-up measurement after two weeks. Outcomes were quick inventory of depressive symptomatology (QIDS) scores and side effects. Results QIDS scores were significantly lower at the last day of therapy (B = - 6.00, p <0.001) and 2 weeks after the end of treatment (B = - 6.55, p <0.001) compared with pre-intervention.
