Bright Light Therapy for Sleep Disturbance in People With Multiple Sclerosis

CompletedNA

Sponsor: Johns Hopkins University

Conditions: Multiple Sclerosis

Interventions: Light therapy

Countries: United States

Sleep disturbance is common in people with multiple sclerosis (MS) and contributes to diminished quality of life. Bright light therapy may be an innovative strategy to reduce sleep disturbance in MS, possibly through its effects on a subtype of retinal ganglion cells that help regulate circadian rhythms and sleep. This pilot study will evaluate whether, in people with MS, bright light therapy reduces sleep disturbance and explore whether light therapy improves function of these cells.
