Although this is depressing news, please continue striving for healthy blood-sugar levels. It may or may not happen to you. Scientific findings not always true for everyone.
“Patients with diabetes can experience several brain changes that develop over time such as shrinkage of areas involved in memory and thinking as well as damage to blood vessels supplying the brain,” Verghese, who wasn’t involved in the study, said by email. “Higher blood sugar levels may be detrimental to the brain even in older adults who do not meet formal criteria for diabetes but are in the gray zone.”
People with diabetes also need to be aware that even if their blood sugar is well controlled, they’re still at increased risk for memory problems and impairments in cognitive function, said Mark Espeland, a researcher at Wake Forest School of Medicine in Winston-Salem, North Carolina.
