00:00More greenery near home was linked to about a 20% lower dementia risk, Swedish researchers found.
00:06The link held over 16 years among older adults living in Stockholm.
00:10Scientists at Stockholm University and the Karolinska Institute followed 2993 adults aged 60 and older.
00:18Over those 16 years, 477 of them developed dementia.
00:22Satellite images tracked trees and plants around each home every year.
00:27Greenery within 100, 250, and 500 meters of each home was measured.
00:31The link was strongest for greenery within 100 meters of home.
00:35It was also more pronounced among women, according to the study in Alzheimer's and dementia.
00:40The team accounted for age, education, lifestyle, air pollution, and traffic noise.
00:46Brain health needs to be considered, said first author Cecilia Stenforce of Stockholm University.
00:51The study is observational, so it shows a link, not proof of cause.
00:57Even so, green space near home was tied to lower dementia risk.
