Having Type 2 diabetes is associated with greater impairment of blood flow to the brain and a sharper decline in mental acuity compared with nondiabetic people of similar age and health status, even over a two-year period, researchers report.

The study, published in Neurology, included 40 people whose average age was 66, half of whom had been in long-term treatment for Type 2 diabetes. All were tested at the start of the study and then two years later with M.R.I. scans, various blood tests and several tests of cognitive ability.

At the end of two years, people with diabetes had greater declines in gray matter volume, composite scores on mental tests, and in rates of blood flow to the brain than those in the control group. They also had greater increases in blood measures of inflammation. Among the group with diabetes, those with more severe declines in cerebral blood flow had correspondingly greater declines on tests of mental skills. Read More
