Failure to control type 2 diabetes may have a long-term impact on the brain, research has suggested.
Severe hypoglycaemic episodes - hypos - occur when blood sugar levels drop dangerously low.
A University of Edinburgh team found they may lead to poorer memory and diminished brain power.
The study, based on 1,066 people with type 2 diabetes aged between 60 and 75, was presented at a conference of the charity Diabetes UK.
