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.
Key Facts
- Long-Term NSAID Use: Associated with a 12% lower risk of dementia.
- Short-Term Use: No significant protective effect was observed.
- Anti-Inflammatory Role: Findings support inflammation’s role in dementia progression.

Past research has suggested that inflammation may contribute to the development and progression of dementia and that non-steroidal anti-inflammatory (NSAID) medications may help protect against dementia due to their anti-inflammatory effects.

A new large prospective study published in the Journal of the American Geriatrics Society provides additional evidence, showing that long-term NSAID use is linked to a decreased risk of developing dementia.
In the population-based study of 11,745 adults with an average follow-up of 14.5 years, 9,520 participants had used NSAIDs at any given time, and 2,091 participants developed dementia. Long-term NSAID use was associated with a 12% reduced risk of developing dementia. Short- and intermediate-term use did not provide benefits.
Also, the cumulative dose of NSAIDs was not associated with decreased dementia risk.
The findings suggest that prolonged, rather than intensive, use of anti-inflammatory medications may help protect against dementia.
“Our study provides evidence on possible preventive effects of anti-inflammatory medication against the dementia process.
“There is a need for more studies to further consolidate this evidence and possibly develop preventive strategies,” said corresponding author M. Arfan Ikram, MSc, MD, PhD, of Erasmus MC University Medical Center Rotterdam, in the Netherlands.
