Light, Metabolic Syndrome and Alzheimer's Disease

Clinical Trial ID: NCT03933696


To test the long term effect of a light treatment on cognition, sleep and metabolism in patients with Mild cognitive impairment (MCI) or mild Alzheimer's disease or related dementia (ADRD).

Test if a tailored light intervention (TLI) that promotes entrainment can improve sleep disturbances, inflammation, insulin sensitivity (Si) and glucose disposal (Sg) and cognition in patients with MCI and mild ADRD and sleep disturbances. Using a single-arm, between-subjects, placebo-controlled study the investigators will investigate if long-term (6-month) exposure to TLI improves glucose homeostasis and insulin sensitivity in patients with MCI and mild AD who suffer from sleep disturbance and are living at home. Participants will be recruited from the Mount Sinai AD research center (ADRC) and randomized to receive the TLI (or comparison control treatment) at home. The investigators hypothesize that, compared to the comparison light, a TLI will increase entrainment, improve sleep, reduce depression, reduce inflammation, improve metabolic control, increase insulin sensitivity, and reduce susceptibility to T2DM and metabolic disease during and after the completion of the 6-month intervention.


Inclusion Criteria: - Mild cognitive impairment - Mild Alzheimer's Disease with an MMSE score of >19 or Clinical Dementia Rating of 0.5 or 1. - Sleep Disturbance - Live at home Exclusion Criteria: - Blindness - insulin-dependent diabetes patients - macular degeneration - severe sleep apnea
