Diabetes may slow brain processing

Some studies have linked diabetes and cognitive dysfunction, but a new study suggests that mental processing speed may be the brain function most severely affected by diabetes. Researchers looked at data from the AGES Reykjavik Study and found that people who had been diagnosed with diabetes were slower to process information than people who didn’t have diabetes. People with undiagnosed diabetes had similar problems, but those with pre-diabetes had mental functioning similar to people without diabetes. Both memory and “executive function or the ability to plan and multitask, were comparable in people with and without diabetes, though people who’d had diabetes more than 15 years also had impaired executive function, according to the report in the American Journal of Epidemiology.
