Impact of Residence Location on Dementia Risk

A study conducted by researchers from Stockholm University and the Karolinska Institute found that living near parks and green spaces reduces the risk of dementia. The specialists analyzed data from 2,993 Stockholm residents aged over 60, monitoring their health over a 16-year period, during which 477 participants developed dementia. Using satellite imagery, the researchers annually assessed the amount of vegetation within 100, 250, and 500 meters of the participants’ homes. The analysis accounted for other factors that could influence the likelihood of developing dementia, such as age, education, lifestyle, socioeconomic conditions, air pollution, and traffic noise. It was found that individuals living in areas with abundant green spaces within 100 meters of their homes were 20% less likely to develop dementia, and this association weakened as green spaces were located farther from residences. This pattern was particularly evident among women. Scientists hypothesize that proximity to nature may positively affect brain health by reducing stress, improving sleep, and enhancing mental well-being. Additionally, green spaces may promote physical activity and social interaction. The study’s organizers emphasized that the benefits are not limited to large parks but also include ordinary trees, green squares, home gardens, and street-side plants.
