Several research has linked Type 2 diabetes with brain shrinkage, difficulties with consideration, and dementia.

A study published in the journal Neurology in September 2012 looked at blood sugar (BSL’s) in individuals who had not been clinically determined to have Type 2 diabetes, so as to discover whether any brain damage occurred with slightly high blood sugar levels. If damage is happening from amounts less than was previously thought, it might be needed to change the meaning of diabetes.
Researchers in the Australian National University looked at blood sugar levels within 266 non diabetic people with regular brain function, aged from sixty to 64 years. Participants with the highest amounts of blood sugar were actually determined to have brain shrinkage according to MRI scans.
