Summary: A new study finds that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with a lower risk of developing dementia. Researchers followed 11,745 adults over 14.5 years and found that those who used NSAIDs long-term had a 12% reduced dementia risk.

However, short-and intermediate-term NSAID use did not provide the same benefit, nor was the total cumulative dose linked to risk reduction. These findings suggest that sustained anti-inflammatory effects may play a role in protecting against dementia.
