New research shows that engaging in regular physical activity before age 50 can significantly reduce the risk of dementia in later life.
A long-term national study involving over 5,000 participants found that individuals who remained physically active throughout life exhibited better cognitive function at age 70, even if they had biological markers of Alzheimer’s disease. Brain scans confirmed that long-term exercise helps preserve brain volume, particularly in regions associated with memory and thinking. The study also revealed that the protective effects of physical activity were more pronounced in women.
Dr Sarah-Naomi James from the UCL Dementia Research Centre stressed the importance of staying active at any stage of life, stating, “It’s never too late to get active.” Meanwhile, David Thomas from Alzheimer’s Research UK highlighted the significance of prevention efforts, emphasizing,
These findings reinforce the role of physical activity in maintaining cognitive health, suggesting that regular exercise should be encouraged as part of dementia prevention strategies.
