Type 2 Diabetes Accelerates Brain Aging & Cognitive Decline

People with type 2 diabetes had consistently and markedly lower cognitive performance compared to healthy individuals who were the same age and similarly educated. People with type 2 diabetes had 13.1% larger decline in executive function that what would be expected by age related effects. Brain processing speed for those with type 2 diabetes was 6.7% slower than for people without type 2 diabetes. Overall, progression of type 2 diabetes was linked with a 26% acceleration of brain aging.

Both aging and type 2 diabetes cause changes in executive functions such as working memory, learning and flexible thinking . . .
