Nineteen patients with late luteal phase dysphoric disorder (LLPDD) and 11
healthy comparison subjects underwent a 3-month crossover trial of bright
(more than 2500 lux) white morning, bright white evening, and placebo dim
(less than 10 lux) red evening light, administered daily for 1 week during
the premenstrual phase of the menstrual cycle. All light treatments
significantly reduced depressive ratings from baseline levels.
