Cognitive impairment in patients with diabetes mellitus

Diabetes mellitus (DB) is associated with cognitive deficit and is characterized by increased risk of dementia development: both vascular dementia and Alzheimer disease. Pathomorphological and neurophysiological findings typical of the brain in patients with DM confirm the presence of cognitive impairment (CI). The pathogenesis of CI is not yet completely understood. But its multifactorial character is clear. It involves metabolic, vascular and degenerative changes related to chronic hyperglycemia and probably caused by negative impact of insulin on the cerebrum. The pattern of CI includes neurodynamic component as well as primary and secondary memory disorders. The efficacy of insulin metabolites as one of the therapeutic approaches to CI administration is under investigation.

Key Words: diabetes mellitus, cognitive impairment, dementia, insulin
