Nonsteroidal anti-inflammatory drugs in Alzheimer's disease
Abstract
We reviewed the records of 210 patients in the Johns Hopkins Alzheimer's Disease Research Center to evaluate the role of nonsteroidal anti-inflammatory drugs (NSAIDs) on clinical features and progression of the disease. We compared patients taking NSAIDs or aspirin on a daily basis (N = 32) to non-NSAID patients (N = 177) on clinical, cognitive, and psychiatric measures. The NSAID group had a significantly shorter duration of illness at study entry. Even after controlling for this difference, the NSAID group performed better on the Mini-Mental State Examination, Boston Naming Test, and the delayed condition of the Benton Visual Retention Test. Furthermore, analysis of longitudinal changes over 1 year revealed less decline among NSAID patients than among non-NSAID patients on measures of verbal fluency, spatial recognition, and orientation. These findings support other recent studies suggesting that NSAIDs may serve a protective role in Alzheimer's disease.
