Evaluating the Disease Modifying Potential of a Sleep Intervention on Alzheimer's Disease (AD) Biomarkers
The study will examine whether 5mg melatonin (over the counter, OTC) over a 9-month period improves Alzheimer's disease (AD) biomarkers and cognitive function in two groups of individuals: those with mild cognitive impairment (MCI+) and those who are not (MCI-). AD biomarkers will be measured from cerebrospinal fluid (CSF) obtained from lumbar punctures. Cognitive function will be evaluated with routine neuropsychological tests. AS OF AUGUST 2024, THE LUMBAR PUNCTURE PROCEDURES FOR THIS CLINICAL TRIAL HAVE BEEN ELIMINATED. THAT IS, PARTICIPANTS ARE NO LONGER RECEIVING A LUMBER PUNCTURE. BUT ARE CONTINUING TO RECEIVE TWO SEPARATE BLOOD DRAWS FOR BIOMARKER TESTING.
• between ages of 56-85 years
• all participants must score 18 or above on Montreal Cognitive Assessment (MoCA);
• all participants must have a clinical dementia rating (CDR) Sum of boxes \<1;
• need to be willing to undergo CSF LP on two occasions over the course of their participation,
• need to be able and willing to stop using any prescription or non-prescription sleep aids (e.g.(e.g. Ambien, Sonata, Lunesta, Belsomra, Rozerem, Halcion, Intermezzo, Doxepin, Melatonin, etc.) for the duration of the study except for study-issued medications
