Lifelong Exercise May Protect Against Dementia,Study Finds
Maintaining an active lifestyle could lead to important changes in the brain that may help stave off dementia,according to a groundbreaking study. Researchers suggest that regular physical activity helps preserve volume in the hippocampus, a critical area of the brain associated with thinking and memory.The study, which analyzed data from the Insight 46 sub-study,followed 468 individuals aged 70 who were part of the National Survey of Health and Growth. This long-term research tracked 5,362 people born in england, Scotland, and Wales during one week in March 1946.Participants provided details on their exercise habits, including walking, swimming, and playing sports, over three decades before and after turning 50. Brain scans were also conducted to assess changes in brain structure.
The findings revealed that those who exercised consistently throughout their lives experienced “better cognitive functioning at age 70, even in those with early markers of Alzheimer’s disease.” Notably, the benefits were more pronounced in women.
David Thomas, head of policy and public affairs at Alzheimer’s Research UK, emphasized, “Dementia is not an inevitable part of ageing, and finding ways to prevent people from ever developing it is indeed a vital part of our mission for a cure.” He added, “While there is no surefire way to prevent dementia, there are some things within our control that can reduce our risk, including keeping active and looking after our heart health, challenging our brains, and keeping connected to the people around us. The evidence shows that it’s never too early or late to start making positive changes.”
The study, published in the journal Brain Communications, found that individuals who exercised at least once a month before the age of 50 had less shrinkage in the hippocampus. This region of the brain plays a crucial role in learning and memory, and its preservation is key to maintaining cognitive health.

| Lifelong exercise is linked to better cognitive functioning at age 70. |
| Benefits are more pronounced in women. |
| Regular physical activity reduces shrinkage in the hippocampus. |
| Exercise may mitigate cognitive decline even in those with Alzheimer’s markers. |
With an estimated 982,000 people living with dementia in the UK—a number expected to rise to over 1.4 million by 2040—this research underscores the importance of physical activity as a potential preventive measure.

The message is clear: staying active isn’t just good for your body—it’s essential for your brain. Whether you’re in your 30s or 70s, it’s never too late to start reaping the benefits of exercise.How Physical Activity Before 50 Could Preserve Brain Health and Delay Dementia Symptoms
New research led by Dr. Sarah-Naomi James from the UCL Dementia Research Centre and the MRC Unit for Lifelong Health and Ageing reveals that staying physically active before the age of 50 may play a crucial role in preserving brain health and delaying the onset of dementia symptoms. The study highlights the importance of exercise in maintaining cognitive function, even in the presence of early brain changes associated with dementia.

- Conclusion
Dr. James and her team discovered that physical activity appears to preserve a specific area of the brain that typically begins to decline with age. “It’s a really critically important part of the brain, and we’re showing that it’s actually larger,” said Dr. James. “We call it preservation of this area of the brain that is usually starting to decline and that is responsible for the early signs of dementia.”
This preservation could explain why physically active individuals are less likely to develop dementia. “People who are physically active are less likely to have dementia,” Dr. James explained. “But what we’re showing is that even before thay have dementia, they are able to tolerate and keep their cognitive function, regardless of [whether] they start to have the early signs in the brain.”
The Role of Exercise Intensity and Timing
The benefits of physical activity before 50 may be linked to the intensity and type of exercise individuals engage in during their thirties and forties. While more research is needed to confirm this, Dr. James noted that future studies could “shed light on the mechanisms of physical activity as a potential disease-modifying intervention.”
Her team’s findings add to the growing body of evidence suggesting that exercise not only supports overall health but also helps the brain tolerate pathology for longer. “It might be to do with this preservation of the specific area of the brain,” she said.
It’s Never Too Late to Start
One of the most encouraging takeaways from the study is that it’s never too late to reap the benefits of physical activity. “It’s never too late, it’s never too early,” Dr. James emphasized. “People who are active, it’s really good for your brain. But actually, even if you are later in life, even starting to have disease symptoms, it could still be beneficial.”
While exercise may not change the disease itself, it could influence “when you might start to develop symptoms.” This finding underscores the importance of incorporating physical activity into daily routines, regardless of age or health status.

How Physical Activity Before 50 Could Preserve Brain Health and Delay Dementia Symptoms
Q: What is teh main focus of the research led by Dr. Sarah-Naomi James?
A: The research led by Dr. Sarah-Naomi James from the UCL Dementia Research Centre and the MRC Unit for Lifelong Health and Ageing focuses on how staying physically active before the age of 50 can preserve brain health and delay the onset of dementia symptoms. The study highlights the role of exercise in maintaining cognitive function, even in the presence of early brain changes associated with dementia.
Q: How does physical activity preserve brain health?
A: Dr. James and her team discovered that physical activity preserves a specific area of the brain that typically begins to decline with age. This area, which is crucial for learning and memory, appears larger in individuals who remain physically active. This preservation could explain why physically active individuals are less likely to develop dementia and are better able to maintain cognitive function despite early brain changes.
Q: What role does the hippocampus play in this research?
A: The hippocampus is a critical region of the brain involved in learning and memory.The study found that individuals who exercised at least once a month before the age of 50 experienced less shrinkage in the hippocampus. This preservation of the hippocampus is key to maintaining cognitive health and delaying dementia symptoms.
Q: Does the intensity and type of exercise matter?
A: Yes, the benefits of physical activity before 50 may be linked to the intensity and type of exercise individuals engage in during their thirties and forties. Dr. James noted that future research could shed more light on the mechanisms of physical activity as a potential disease-modifying intervention.
Q: Is it ever too late to start exercising for brain health?
A: No, it’s never too late to start. Dr. james emphasized that even starting exercise later in life can still benefit brain health. While exercise may not change the disease itself,it could influence when individuals start to develop symptoms of dementia. This underscores the importance of incorporating physical activity into daily routines, nonetheless of age or health status.
