Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The goal of this pilot project is to determine whether melatonin levels are disordered in patients with Smith-Magenis Syndrome (SMS) and whether melatonin treatment can correct abnormal circadian rhythms in SMS patients. In addition, the study investigates the effects of bright light in an elderly control population that exhibits low melatonin secretion.

Investigators
