Diabetes 'rewires' the brain in surprising way, study finds

In a new study, researchers found that type 2 diabetes can "rewire" the brain in ways similar to early Alzheimer's disease. Experts comment on the link between high blood sugar and cognitive decline....                        ...                        ...                            ...Diabetes is known to cause many medical issues, from You are not allowed to view links.

It's possible those other aspects may have different, either compounding or allaying, impacts." ......Hyman's team plans to conduct further research into the connection between diabetes and brain function......."Alzheimer's disease goes undetected for decades because our brains are good at finding ways to compensate," he said. ......"Before diagnosis, people behave normally despite having changes in information processing.
