Abstract
Type 2 diabetes mellitus (T2DM) imparts an increased risk for cognitive decline, specifically executive function, which is important to maintain for diabetes self-management. There is evidence to suggest that exercise improves cognition in healthy older adults; however, the literature in adults with T2DM is lacking. This commentary is in complement to Podolski et al.'s systematic review evaluating the effects of physical activity on cognitive function in adults with T2DM. We have included eight additional studies and further highlight their conclusions on the heterogeneity of the literature thus far. Three current issues with the literature are as follows: (1) variability in interventions (e.g., aerobic, resistance, lifestyle, and yoga), (2) variability in cognitive outcome measures, and (3) lack of detailed description of the population studied, for example, baseline glycated hemoglobin (A1C) values. Overall, making it difficult to compare these studies and draw final conclusions. Thus, the efficacy for exercise to improve cognition in adults with T2DM is not yet well understood. Potential ways to mitigate these limitations could be for future studies that (1) use robust methodology whenever possible, that is, randomized contr...Continue Reading
