Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Whereas the advantageous effects of exercise-training on memory is increasingly recognized, the practicality and clinical usefulness of such interventions in community-dwelling older African Americans (AA)s Mild Cognitively Impaired (MCI) subjects, and the mechanism by which an effect occurs need elucidation. Because aerobic-exercise can improve emerging cardiovascular (CVD)-related risk factors for cognitive decline such as lipids, inflammatory cytokines and glucose homeostasis; the Investigators will examine training effects on these and related biomarkers. The imperative for this study is further underscored by the fact that, AAs: i) have high rates of dementia, and ii) have paucity of cross-sectional, and lack prospective data on the effects of exercise on cognition. To overcome barriers to recruitment and retention, enhance compliance with a long exercise program (3-times/week), and maximize the use of available resources, the Investigators will use a community-based approach. Therefore, the primary objectives of this study build on the Investigators' experience, and will compare the effects of aerobic-exercise to stretch-exercise (control) in community-dwelling AA MCI subjects. Following the initial 6 months active intervention, the aerobic-exercise group will follow a prescribed but free living 40 minutes, 3 time/week exercise regimen while the control group returns to usual care plus stretch-exercise for additional 12 months. This study will facilitate the estimation of sample size for a larger confirmatory study in AAs. A newly acquired direct oversight of the DC Ward-6 Senior Wellness Center and its infrastructures by the Howard University Division of Geriatrics will provide additional resources and access to the community. In addition to the Investigator's feasibility aims, the Investigators will determine performance on cognitive tasks using the Alzheimer's Disease Assessment Scale-Cognitive Sub-scale (ADAS-Cog) and Clinical Dementia Rating Scale (CDR) sum of boxes supplemented by tests of executive function (EF) and Functional Activity Questionnaire (FA) and together as ADAS-Cog-Plus; changes in brain volume regions of interest (ROI) with Magnetic Resonance Imaging (MRI), selected CVD and AD-related bio-markers.
