Dementia is the most important cognitive complication of diabetes. A study was carried out to know whether strict control of diabetes can prevent cognitive decline in cognitive decline in diabetics.  At present the results do not support specific treatment prevent cognitive decline in diabetes.

It is important for people with type 2 diabetes to keep their blood sugar under control to reduce the likelihood of long-term complications. While the study didn’t confirm cognitive advantages, many other health benefits are associated with well-controlled blood sugar.

People older than 70 with type 2 diabetes are twice as likely suffer mental impairment as those without diabetes, researchers say. Intensively controlling blood sugar has been shown to reduce the odds of diabetes complications, such as vision, kidney and circulation problems, so it seemed likely that it might also slow any cognitive decline related to the condition.

There was no difference in cognitive function between people who received the intensive strategy versus the standard strategy. Patients should follow standard therapy, because there is no additional benefit to following a more intensive strategy.
