[The Effect of Hyper- and Hypoglycaemia on Cognition and Development of Dementia for Patients with Diabetes Mellitus Type 2].

Diabetes mellitus Type 2 is associated with cognitive decline and a risk for developing dementia. The reason for this correlation is poorly understood, but evidence suggests insulin resistance, hyperglycaemia and glucose variability as likely culprits, whereas hypoglycaemia is a marker for cognitive decline rather than the cause. Inflammation and microvascular damage are possible common pathologies.
