Diabetes and cognitive function: preliminary studies

Summary lationships between diabetes mellitus and cognitive function were studied in patients aged over 50 years with good metabolic control and without chronic complications. The following tests were performed: CES-D, Reyʹs, Bentonʹs, Spanʹs, Corsiʹs, MMSE, Ravenʹs. No differences were found in the comparison between groups (12 diabetics and 17 normals) contrary to other similar studies. This could be for the bad metabolic control of patients studied in previous studies or for the existence of minimal deficit not shown with the conventional tests.
