Mentally Active Versus Passive Sedentary Behavior and Risk of Dementia: 19-Year Cohort Study
Key Points
The study examines the relationship between different types of sedentary behavior and the risk of developing dementia over time.
Conducted a 19-year cohort study focusing on older adults.
Compared mentally active sedentary behaviors with passive ones.
Assessed the impact of physical activity on dementia risk.
Mentally passive sedentary behavior is linked to a higher risk of dementia.
Replacing passive activities with mentally active ones may decrease this risk.
Physical activity also contributes positively to reducing dementia risk.
Abstract
Mentally passive sedentary behavior may increase the risk of dementia. Replacing passive with mentally active sedentary behaviors or with physical activity may reduce the risk of dementia in older adults.
