Dementia Risk Linked to Sedentary Activities, Study Finds
Mentally active sedentary behaviors require cognitive engagement, while passive ones do not.
Replacing passive time with active behavior reduces dementia risk by 7%.
Adding active behavior reduces risk by 4%; combining with physical activity reduces it by 11%.
Social interaction and group hobbies support brain health.
Study shows association, not causation; other factors like diet, sleep, and fitness matter.
