Sedentary Lifestyle Identified as a Key Risk Factor for Alzheimer's Disease in 7-Year Study

Recent research highlights the significant impact of sedentary behavior on the risk of developing Alzheimer's disease. A comprehensive 7-year study conducted by researchers from Vanderbilt University Medical Center and the University of Pittsburgh found that increased sitting or lying down time in older adults is linked to cognitive decline and brain shrinkage, particularly in regions associated with Alzheimer's disease. The study involved 404 participants aged 50 and above, who wore activity monitors over a week to track their sedentary time. Findings revealed that individuals spending more time sedentary experienced greater neurodegeneration and cognitive deterioration, independent of their physical activity levels. Notably, this association was even stronger among those carrying the APOE-e4 genetic risk factor for Alzheimer's. Experts emphasize that reducing sedentary time, even beyond regular exercise, could be crucial in lowering the risk of neurodegeneration. Dr. Marissa Gogniat underscored that minimizing sitting time complements physical activity in protecting brain health, especially for genetically at-risk populations. This research underscores the importance of lifestyle modifications, such as frequent breaks and movement throughout the day, in front-line strategies to prevent Alzheimer's and promote healthy aging.
