Exercise May Protect the Aging Brain From Alzheimers

Show Voice Options Emerging research suggests that regular physical activity may help protect the ageing brain by reducing the accumulation of harmful proteins associated with Alzheimer's disease and lowering chronic inflammation that contributes to cognitive decline; scientists found that adults who engage in consistent moderate exercise - such as brisk walking, cycling or swimming - tend to exhibit lower levels of beta-amyloid and tau proteins, markers linked to Alzheimer's pathology, as well as improved blood flow and reduced inflammatory signals in neural tissue compared with less-active peers, offering important insights into how lifestyle behaviours can influence brain resilience and potentially delay or reduce the risk of dementia.
