Why the study?
Does Type 2 diabetes mellitus affect executive functioning in older adult outpatients compared to controls?
Does Type 2 diabetes mellitus affect executive functioning in older adult outpatients compared to controls?
Older adult outpatients with Type 2 diabetes show specific deficits in the executive domain of inhibition compared to controls, while other executive domains remain unaffected.
May support selective inhibition screening in older T2DM outpatients; leaves open broader executive effects and clinical outcomes.
Given the multi-componential nature of executive functions, we compared 48 outpatients affected by Type 2 diabetes and 49 control subjects on the executive domains of inhibition, updating, shifting, and word fluency. Variables commonly associated with diabetes were considered in explaining the relationship between diabetes and executive functioning. Each participant underwent a clinical and cognitive (addressing the four executive domains) evaluation. Raw test scores were standardized per domain and compared between groups. Possible risk factors related to diabetes were examined. The diabetes group scored lower than the control subjects only in the inhibition measure, whereas no differences resulted in the other executive domains.
