Diabetes drug benefit

Type 2 diabetes is a major risk factor for dementia, but new research suggests that a drug used to treat the diabetes simultaneously reduced the risk of dementia.

Scientists at Seoul University discovered that people with type 2 diabetes who were prescribed pioglitazone had a lower dementia risk compared with those who weren’t prescribed the drug.

“Our brains do not operate in isolation, and to find effective ways to reduce dementia risk, we need to investigate how other conditions, and their treatments, impact our brain health,” said Alzheimer’s Research UK head of research Dr Rosa Sancho.

The study was published in the journal Neurology.
