Executive functions in patients with Alzheimer's disease, type 2 diabetes mellitus patients and cognitively healthy older adults

摘要

Objectives: The present study investigated whether the performance on executive function tasks of patients with type 2 diabetes mellitus (T2DM) is as impaired as that of Alzheimer's disease (AD) patients and to compare their performance with that of a group of cognitively healthy older adults. We also investigated whether glycosylated hemoglobin levels (HbA1c, a measure of glucose regulation) are related to performance on executive control tasks.
