Some anti-inflammatories could also reduce the risk of dementia, study shows

Usually used for aches and pains, a new study has found the prolonged use of non-steroidal anti-inflammatories could also reduce the risk of dementia.

Most people have non-steroidal anti-inflammatories in their medicine cupboards, such as aspirin, ibuprofen, and Voltaren.

A peer-reviewed study published in the Journal of the American Geriatrics Society spanning 30 years has found the drugs could also help protect our brains.

The study involved more than 11,000 people aged 55 years and older and found those who used anti-inflammatories long-term for more than two years had an 18 per cent lower risk of dementia than those who didn't take anything.

"There's a lot we're learning about dementia and the different causes of dementia being associated with higher inflammation in the brain and blood, so we're looking at using anti-inflammatories as a potential to treat or reduce dementia," geriatrician Paul Yates from the University of Melbourne Austin Health said.

The short-term use of anti-inflammatories – for less than two years – saw a slightly increased risk of dementia.

One explanation could be their inflammation wasn't as controlled as long-term users.

The study also found having higher doses of the drug wasn't beneficial – it was the prolonged use that helped.

While the study is significant, experts say you shouldn't rush out and start taking anti-inflammatories.
