Diagnosis of type 2 diabetes before the age of 50 nearly doubles the risk of dementia, while concurrent obesity triples the risk.
“A recent study found that the age at which a person develops type 2 diabetes influences their risk of developing dementia, with obesity more than tripling risk, especially at younger ages. Researchers tracked more than 1,200 adults aged 50 and older who had diabetes but no dementia at the start of the study.”
