For people with type 2 diabetes, intense treatment doesn’t slow decline in thinking skills, a new study found. Super-strict blood sugar control actually appeared to increase study participants’ risk of death, the researchers found. People older than 70 with type 2 diabetes are twice as likely to 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.
