Diabetes drug may slow Alzheimer's

A trial has begun to see whether a drug used to treat diabetes can slow the progression of Alzheimer's disease.

The 200 patients on the trial will receive a daily injection of liraglutide or a placebo for 12 months, and will have scans and memory tests before and after the treatment.

Research suggests that the drug reduces brain inflammation, improving the growth of brain cells and the connections between them.

Fergus Walsh reports.
