Brief Summary

Increased dietary intake of niacin is correlated with reduced risk of Alzheimer's Disease and age-associated cognitive decline. The goal of this study is to collect data on the penetration of commercially available, FDA approved, extended-release niacin into the spinal fluid. One dose of 500 mg nicotinic acid will be used (in addition to placebo) to build a dose response curve for this compound in human cerebrospinal fluid. This objective will demonstrate target engagement of HCAR2 in the central nervous system, after oral treatment with niacin. The primary endpoints are to show increased nicotinic acid levels in blood and cerebrospinal fluid. A secondary endpoint is to collect safety and tolerability data of niacin in this particular population.
