Controlling blood sugar levels improved the ability to clearly think, learn and remember among people with type 2 diabetes who were overweight, a new study shows. But losing weight, especially for people who were obese, and increasing physical activity produced mixed results.
“It’s important to properly control your blood sugar to avoid the bad brain effects of your diabetes,” said Owen Carmichael, Ph.D., Professor and Director, Biomedical Imaging at Pennington Biomedical Research Center. “Don’t think you can simply let yourself get all the way to the obese range, lose some of the weight, and everything in the brain is fine. The brain might have already turned a corner that it can’t turn back from.”
