In the past 20 years, substantial evidence from laboratory and epidemiologic studies has suggested that anti–inflammatory medications could defer or prevent the occurrence of Alzheimer's disease (AD). However, several studies do not corroborate these findings. In this systematic review and meta–analysis, researchers evaluated the association between anti–inflammatory drug use and the incidence of AD. They concluded that while observational studies support the use of NSAIDs for prevention of AD, a randomized controlled trial (RCT) did not. They argue that well–designed studies and innovative approaches are required to illuminate the exact relationship between NSAID use and AD risk, as well as the appropriate dosage and duration of use to maximize benefit and safety.
Methods
- Pubmed, Embase, and Cochrane Library databases were searched up to March 2014.
- Studies evaluating the association between use of anti–inflammatory drugs and AD risk were included.
- Relative risks (RRs) with 95% confidence intervals (CIs) were meta–analyzed using random effects models, and were grouped by anti–inflammatory type and duration of drug use.
- In observational studies, use of non–steroidal anti–inflammatory drugs (NSAIDs) was significantly associated with a reduced risk of AD (RR, 0.72; 95% CI, 0.62–0.84) compared to no use of NSAIDs, especially in long–term users (RR, 0.36; 95% CI, 0.17–0.74); the risks of AD were also lower in both aspirin (RR, 0.77; 95% CI, 0.63–0.95) and non–aspirin NSAID users (RR, 0.65; 95% CI, 0.47–0.88) compared with nonusers; whereas the use of corticosteroids showed no significant association (RR, 0.62; 95% CI, 0.26–1.46).
- In the single RCT, NSAID use showed no significant effect on AD risk among dementia–free individuals (P<0.05).
