Excessive Sitting Linked to Rapid Increase in Dementia Risk

Adults aged 60 and older who spend over 10 hours a day engaged in sedentary behaviors, such as sitting while watching TV or driving, may be at an increased risk of developing dementia, according to a study published in JAMA. The research analyzed data from approximately 50,000 adults and found that sedentary behavior was linked to a higher risk of dementia. However, lower levels of sedentary behavior, up to around 10 hours, were not associated with increased risk. Further studies are needed to establish causality and determine if physical activity can mitigate the risk of developing dementia.
