Common Medicines Associated With Dementia Risk (BBC News / JAMA Internal Medicine)

Summary

A US study, published in JAMA Internal Medicine, concerning long-term use of anticholinergic-type drugs (those which block the neurotransmitter acetylcholine), in older people, has discovered an association with the risk of developing dementia. Higher doses and prolonged use of these commonly prescribed medicines is linked (statistically) to a higher dementia risk in elderly people.

“The most commonly used anticholinergic-type drugs were medicines for treating depression, antihistamines for allergies such as hay-fever or to aid sleep/promote drowsiness, and drugs to treat urinary incontinence. Nearly a fifth were drugs that had been bought over the counter”.

This study included prescribed medicines only.

The mechanism(s) by which anticholinergics might contribute to dementia risk are not known.
