Dementia risks were lowered through the use of a diabetes drug.

A frequently prescribed diabetes drug may reduce the risk of older adults developing dementia, researchers from the German Center for Neurodegenerative Diseases found. 

A study found that older adults who take pioglitazone, a medication used for treatment of diabetes in those who can still produce insulin, are less likely to develop dementia.

Of the 145,000 people 60 and older who were studied, those who took pioglitazone had a 47% lower chance of developing dementia than non-diabetics. Results were most favorable among patients taking the drug for at least two years.
