The main goal of this study was to assess cognitive dysfunctions in patients with type 2 diabetes, in comparison to pre-diabetic patients as well as normal subjects. Another aim was providing insight into cognitive dysfunctions in the early stage (pre-diabetic stage) of the disease. Method: The samples comprised of 32 patients with type 2 diabetes, 28 pre-diabetic patients and 30 healthy subjects. It was hypothesized that there might be possible differences among patients with type 2 diabetes, prediabetic patients and normal subjects. Cognitive performances were assessed by Paced Auditory Serial Addition Test (PASAT), Rey Complex Figure Test (RCFT) and subtests of Wechsler Adult Intelligence Scale – Revised (WAIS–R) Test. Results: The results showed that there were significant differences in memory and information processing speed between patients with type 2 diabetes, pre-diabetic patients, and normal subjects (p ≤ 0.05). Conclusion: The results showed that there were differences in patients with type 2 diabetes and pre-diabetic patients. Therefore, monitoring the neuropsychological status, and controlling levels of blood sugar for these patients are important. Addressing various reports that studied the influence of type 2 diabetes on cognitive performance, the findings of the present study suggest that they are in accord with the literature, and stress that patients with type 2 diabetes and pre-diabetic patients experience a decline in their cognitive performance. %> http://icssjournal.ir/article-1-361-en.pdf %P 33-40 %& 33 %! %9 Research %L A-10-2-340 %+ Clinical Psychology, University of Isfahan %G eng %@ 1561-4174 %[ 2011
