Cortical function in elderly non-insulin dependent diabetic patients. Behavioral and electrophysiologic studies.

Neurobehavioral and electrophysiologic studies were carried out to determine the effect of diabetes mellitus on cognitive function in subjects over the age of 60 years. Forty-three non-insulin-dependent diabetic men were compared with 41 male nondiabetic age-matched controls. The diabetic patients were significantly inferior to the control group in the serial learning task and Benton's Visual Retention Test.
