Non-steroidal anti-inflammatory (NSAIDS) drugs such as Naproxen and Celecoxib do not improve cognition in at-risk older adults. These findings from the Alzheimer’s Disease Anti-Inflammatory Prevention Trial (ADAPT) were published this month in Archives of Neurology. The Roskamp Institute Memory Clinic in Tampa was one of a handful of centers across the United States that took part in this primary prevention trial funded by the National Institute of Aging. The Tampa site enrolled over 400 subjects, age 70 or older with a reported family history of Alzheimer’s-like dementia. During the 5-year study period, participants underwent annual cognitive testing and were randomly assigned to one of two treatments (Naproxen 220 mg twice daily, Celecoxib 220 mg twice daily) or a placebo. Although treatment was suspended in 2004, following a report of increased cardiovascular risk in another prevention trial, subjects continued annual follow-up. Results examining the cognitive data collected up to 6 months after treatment was discontinued suggest that Naproxen may in fact have a small deleterious effect on cognition. However further study is needed to determine if this effect is mitigated or exaggerated over time, or if results were influenced by subjects who may have been in the early stage of a dementia. Drs. Cheryl Luis and Timothy Crowell, specialists in Neuropsychology, supervised the day-to-day aspects of the study in Tampa. Dr. Michael Mullan, director of the Roskamp Institute and principal investigator for the Tampa site served on the writing committee of the manuscript.
