Painkiller slows memory loss

A common painkiller associated with menstrual cramps could be a tool to reversing memory loss caused by Alzheimer's disease, researchers assert.

The anti-inflammatory drug mefenamic acid was given to mice genetically modified to develop Alzheimer's. Another group of similar mice received placebos.

After a one-month period, researchers at the University of Manchester in England discovered that mice given mefenamic acid had memory levels similar to mice that were Alzheimer's-free.

The investigators said mefenamic acid targets a “pro-inflammatory” pathway that's known to damage brain cells.

“There is experimental evidence now to strongly suggest that inflammation in the brain makes Alzheimer's disease worse," said David Brough, Ph.D.
