Physical activity and green spaces linked to slower cognitive decline

New research suggests that lifestyle factors and environmental surroundings play significant roles in mitigating cognitive and motor decline.

A study published in the journal Neurology by researchers at the University of Cincinnati examined 294 patients with mild to moderate Parkinson’s disease. The findings indicate that higher levels of physical activity are associated with a slower progression of both motor difficulties and cognitive impairment. Participants with higher activity levels showed significantly lower annual decreases in Montreal Cognitive Assessment scores compared to those with lower activity levels.

Separately, a 16-year Swedish study published in Alzheimer’s & Dementia found that proximity to vegetation may reduce dementia risk. Researchers from Stockholm University and the Karolinska Institute observed that older adults living with more vegetation within 110 meters of their homes had a 20% lower risk of developing dementia. The study suggests that green spaces may promote brain resilience by encouraging physical activity, social contact, and better sleep, while reducing exposure to noise and pollution.
