Diabetes may influence cognitive decline

In women, having type 2 diabetes makes poor cognitive function and substantial cognitive decline over time more likely. Logroscigno and colleagues (p 548) extracted data from the nurses' health study on more than 16 000 women aged 70-81 years, and assessed cognitive function twice over two years. They found that women with type 2 diabetes had poorer cognitive function and cognitive decline than women without diabetes, especially if they had had diabetes for more than 15 years. Women who where not taking drug treatment for diabetes were at higher risk, but those taking oral hypoglycaemic agents had a similar risk as women without diabetes.
