Physical activity reduces dementia risk by 28% and stroke risk up to 80%

Research presented in Zurich and London shows that regular physical activity can lower the risk of developing dementia by 28% and may cut stroke risk by as much as 80%, driven by measurable changes in brain structure and neuroplasticity. Studies highlight that targeted, challenging exercise promotes vascular health, cognitive reserve, and adaptive neural pathways, outperforming simple repetitive brain‑training apps.

At a conference in Rome, Guido Bellomo of Italy’s Istituto Superiore di Sanità cited evidence that roughly 45% of dementia cases could be avoided through lifestyle‑focused prevention. He referenced the European Joint Action Jade Health project, which aims to raise public and professional awareness and provide tools for self‑managed risk‑factor modification, linking scientific guidance with everyday behavior.

Both reports stress that combined interventions—exercise, Mediterranean‑style diet, and mental disciplines such as yoga—offer the most robust protective effect against cognitive decline and cerebrovascular events.
