Synopsis
A groundbreaking study reveals that reducing sedentary time may significantly lower the risk of developing Alzheimer's disease, especially among older adults. Discover how lifestyle choices impact brain health and learn the importance of staying active to protect cognitive function.
Key Takeaways
- Reducing sedentary behavior is essential for cognitive health.
- Exercise alone is not sufficient; one must also minimize sitting time.
- Older adults carrying the APOE-e4 allele should be particularly mindful of their sedentary habits.
- Regular movement and breaks from sitting can help in preventing neurodegeneration.
- The study emphasizes the importance of lifestyle habits in lowering Alzheimer's risk.
New Delhi, May 13 (NationPress) A recent study indicates that increased sedentary behavior, including time spent sitting or lying down, correlates with poorer cognitive function and brain shrinkage in regions associated with the risk of developing Alzheimer’s disease.
The research conducted by scientists at Vanderbilt University Medical Center (VUMC) and the University of Pittsburgh seeks to understand how lifestyle choices influence the likelihood of developing this disease.
Published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, the study emphasizes that reducing the risk of Alzheimer’s is not solely about engaging in daily exercise,” stated Marissa Gogniat, Assistant Professor of Neurology at Pitt.
“Minimizing the time spent sitting, even with regular exercise, significantly lowers the risk of developing Alzheimer’s disease,” she added.
The research team investigated the connection between sedentary behavior and neurodegeneration in a sample of 404 adults aged 50 and above.
Participants were equipped with a watch that continuously tracked their activity over a week. The amount of sedentary time was then correlated with cognitive performance and brain scans conducted over a seven-year follow-up.
Those who spent extended periods in sedentary activities were more prone to cognitive decline and neurodegenerative alterations, regardless of their exercise habits.
Moreover, the association between sedentary time and Alzheimer’s risk was notably stronger in individuals carrying the APOE-e4 allele, a genetic risk factor for Alzheimer’s disease. This suggests that reducing sedentary time is particularly crucial for older adults with increased genetic susceptibility to Alzheimer’s.
The findings indicate that less sitting could serve as an effective strategy for preventing neurodegeneration and associated cognitive decline.
“This research underscores the necessity of limiting sitting time, especially among older adults at higher genetic risk for Alzheimer’s disease. It's vital for our brain health to take breaks from sitting and to move throughout the day,” commented Angela Jefferson, Professor of Neurology at VUMC.
Point of View
I believe the findings of this study shed light on a critical aspect of public health. Reducing sedentary time presents a simple yet powerful approach to mitigating the risk of Alzheimer’s disease. It’s a call to action for all of us, especially older adults, to prioritize movement in our daily routines to safeguard cognitive health.

Frequently Asked Questions
What is the link between sedentary behavior and Alzheimer's disease?
Studies indicate that increased sedentary behavior is associated with cognitive decline and brain shrinkage, increasing the risk of developing Alzheimer's disease.
How was the research conducted?
Researchers monitored the activity levels of 404 adults aged 50 and older over a week and correlated sedentary time with cognitive performance and brain scans over seven years.
Why is it important to minimize sitting time?
Minimizing sitting time, even with regular exercise, is crucial as it significantly reduces the likelihood of developing Alzheimer's disease and supports overall brain health.
