Exercise Delays Onset of Alzheimer's Disease by Jayashree on June 11, 2021 at 11:16 PM In old people aerobic exercise training increases gray and white matter volume, enhances blood flow and improves memory function so the ability of systemic biomarkers measuring exercise effects on brain function related to metabolomic alterations associated with risk for AD used for further prevention, monitoring, and treatment efforts. To address this issue, Henriette van Praag, Ph.D., from Florida Atlantic University's Schmidt College of Medicine and Brain Institute and Ozioma Okonkwo, Ph.D., Wisconsin Alzheimer's Disease Research Centre and Department of Medicine at the University of Wisconsin-Madison and their collaborators, tested the hypotheses that three specific biomarkers implicated in learning and memory will increase in older adults following exercise correlated with cognition and metabolomics markers of brain health.
