NCT00006517

Brief Summary

We are offering non-pharmacologic therapy for alleviation of symptoms associated with depressed mood that recurs annually in fall or winter. The treatments are self-administered at home by the patient, with close clinical supervision. Our trials use specially designed devices that replenish two different environmental elements, naturally occurring light and negative ions in the air. Both factors may be reduced in winter, bringing on depression.
