Nonsteroidal anti-inflammatory drugs (NSAIDs) include naproxen (Aleve) and ibuprofen (Motrin). Epidemiological studies going back decades raise the possibility that they may be protective in Alzheimer’s disease. In 2018, a meta-analysis of 16 such studies seemed concluded that the risk reduction was 20%. This conclusion was not supported by a large randomized placebo-controlled trial using naproxen and Celebrex in adults with a family history of dementia, but some of the cognitive tests seemed to show benefit in the naproxen group.

This uncertainty led a new 2-year double-blind, placebo-controlled prevention trial in “pre-symptomatic” Alzheimer’s. Subjects had positive family history of Alzheimer’s and a mean age of 63 years. Naproxen dose was 220 mg twice a day, the usual over-the-counter dose. There was no benefit over placebo and the naproxen group had more side effects but no serious safety issues.
