Diminished Performance on Response-Selection Tasks in Type 2 Diabetes

Comparisons of visual perception, response-selection, and response-execution performance were made between Type 2 diabetes mellitus patients and a matched nondiabetic control group. 10 well-controlled male patients with Type 2 diabetes without diabetic complications (M age 58 yr.) and an age and IQ-matched nondiabetic control group consisting of 13 male healthy volunteers (M age 57 yr.) were included. Significant differences were round only between the two groups on response-selection performance, which concerns the selection and preparation of an appropriate motor action.
