Type II diabetes is a chronic disease characterized by high blood glucose levels. It needs to be treated with diet, oral drugs and sometimes insulin to control symptoms and avoid organ damage. Patients may develop features of cognitive decline (e.g. memory problems) earlier than healthy people. This review tries to clarify whether the type of treatment or control of the glycemia influences cognitive function. None of the studies identified had sufficient high quality data to justify any conclusion. Future trials of treatment for Type II diabetes should include measures of cognitive function as an outcome.
