Disease modifying potential of 5mg of melatonin on cognition and brain health in aging

Neurology Healthy Subjects Adult Subjects Female Subjects Male Subjects

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.
