Diabetes Mellitus, Type 2 Clinical Trial
Official title:
Feasibility Testing a Randomized Controlled Trial of an Exercise Program to Improve Cognition for T2DM Patients
This proposed study will advance science by providing evidence on the feasibility of a standardized, rigorously designed and delivered exercise program to improve cognition and plasma brain-derived neurotrophic factor (BDNF) levels for individuals with type 2 diabetes. We will also explore how certain genetic variant may influence exercise-induced cognitive improvements and plasma BDNF levels. Findings of the proposed study will establish a comprehensive knowledge base for future research and development of a personalized exercise program for high-risk individuals who are vulnerable to cognitive dysfunction based on their genomic profiles.
The study will pilot-test a 3-month supervised exercise program to improve plasma brain-derived neurotrophic factor (BDNF) levels and domains of cognition that are mostly affected in type 2 diabetes mellitus (T2DM), including memory, processing speed, and executive function, overall and according to genotypes of the BDNF Val66Met variant. T2DM impairs the brain, leading to cognitive dysfunction, which carries substantial lifetime consequences. This highlights an urgent need to find effective therapeutic strategies to improve cognitive function among those with T2DM. Aerobic exercise enhances cognitive function among healthy subjects through increased release of BDNF. BDNF supports survival of existing neurons and promotes growth of new neurons and synapses. Emerging evidence suggests that reduced BDNF levels may exacerbate cognitive dysfunction associated with T2DM. Compared to drug delivery of BDNF, aerobic exercise is a low- cost, safe, and easily accessible path to increasing endogenous BDNF levels. In persons with T2DM, integrity of the blood-brain barrier (BBB) is impaired. Although a growing body of evidence supports the protective role of regular exercise in BBB integrity, very little is known about how resting peripheral BDNF levels may change in response to regular aerobic exercise training after adjusting for BBB permeability among individuals with T2DM. One critical genetic variant that affects cognition in human is the BDNF Val66Met variant. The Met allele interferes with the activity-dependent secretion of mature BDNF among Met carriers. Despite the strong evidence suggesting aerobic exercise has a beneficial effect on cognitive function, significant variability in individual response to exercise training in cognitive outcomes has been reported among Val/Val vs. Met carriers. However, the evidence on how the BDNF Val66Met variant influences cognitive outcomes following an aerobic exercise intervention among individuals with T2DM is currently lacking. A total of 84 participants with T2DM will be randomized 2:1 to receive aerobic exercise intervention (n=56) or attention control (n=28) for 3 months. The study will evaluate the feasibility of the intervention. The study will also evaluate preliminary effectiveness of the supervised exercise program on cognitive function and plasma BDNF levels after controlling BBB permeability. An exploratory aim is to explore the influence of the BDNF Val66Met polymorphism on cognitive outcomes and plasma BDNF levels in response to aerobic exercise intervention. The purpose of this study is well aligned with the National Institute of Nursing Research (NINR) mission to develop personalized interventions that address mechanisms underlying symptoms of illness through symptom science research. Based on the findings of this proposed study, our long-term goal is to develop a personalized exercise program for high-risk individuals susceptible to cognitive dysfunction based on their genomic profiles. ;
