Summary
Nearly 3,000 people followed for 16 years showed a 20% lower dementia risk when more greenery surrounded their homes, according to Stockholm University and Karolinska Institute researchers.
The protective link was strongest within 100 meters of home and weakened as distance from green areas increased, pointing to immediate surroundings rather than citywide access.
Researchers said nearby vegetation may cut risk by easing stress and improving sleep, physical activity and social interaction, while also buffering traffic noise, air pollution and extreme heat.
With dementia cases in the EU estimated at 9 million in 2025 and projected to top 14 million by 2050, the authors said urban planning should protect and expand accessible residential green space.
