There is existing evidence linking type 2 diabetes with cognitive decline, but it can be difficult to distinguish between normal aging of the brain that begins in middle age and brain changes linked to diabetes. To define the effects over and above normal aging, a team of British scientists used a databank of twenty thousand people over the age of fifty, including brain scans and brain function information. Results showed both normal aging and diabetes cause changes in working memory, learning and flexible thinking, but people with diabetes had an additional thirteen percent reduction in these executive functions in their brain. The study suggests brain imaging may be able to see those changes long before traditional diagnosis of diabetes.
