A groundbreaking new study suggests that staying active throughout life could significantly reduce the risk of dementia. Researchers believe this is due to exercise promoting brain volume in the hippocampus, a region crucial for memory and thinking.
The study, published in the journal Brain Communications, analyzed data from Insight 46, a long-term health study following over 5,000 individuals since their birth in 1946. Researchers focused on 468 participants aged 70, examining their exercise habits over three decades and analyzing brain scans.
The results were compelling: regular exercise throughout life was linked to better cognitive function at age 70, even in those with early signs of alzheimer’s disease, such as amyloid buildup. Interestingly, this benefit was more pronounced in women.
“Dementia is not an inevitable part of ageing,” states David Thomas, Head of Policy and Public Affairs at Alzheimer’s Research UK, a key funder of the study alongside the Medical Research Council.”Finding ways to prevent people from ever developing it is a vital part of our mission for a cure.”
The study found that individuals who exercised at least once a month before 50 showed less shrinkage in their hippocampus. Dr. Sarah-Naomi James, a researcher at UCL’s Dementia Research Centre, explained, “It’s a really important part of the brain, and we’re showing that it’s actually larger in those who exercise regularly. 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.”
While more research is needed to pinpoint the exact mechanisms, James suggests that the intensity and type of exercise undertaken in the thirties and forties might play a role. Future studies could explore how physical activity might act as a disease-modifying intervention.
“We look at something like dementia and we say, ‘There’s a pattern that we can see replicated lots of times: people who are physically active, they’re less likely to have dementia,’” James explains. “But what we’re showing is that even before they have dementia, they are able to tolerate and keep their cognitive function, nonetheless of [whether] they start to have the early signs in the brain. It might be to do with this preservation of the specific area of the brain. And then, also, you’re able to tolerate the pathology for longer.”
While exercise may not entirely change the course of Alzheimer’s disease, James emphasizes its potential to delay symptom onset: “It’s never too late, it’s never too early. 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.”

The Brain-Boosting Power of Exercise: A New Study on Dementia Prevention
An Interview with dr. Sarah-Naomi James
A groundbreaking new study suggests that staying active throughout life could substantially reduce the risk of dementia. Researchers believe this is due to exercise promoting brain volume in the hippocampus, a region crucial for memory and thinking. Dr. Sarah-Naomi James is a researcher at UCL’s Dementia Research Center and one of the lead authors of this promising study published in Brain Communications. We spoke to her about her findings and what they mean for us.
Archyde: Dr. James, can you tell our readers about this groundbreaking study and its key findings?
Dr. James: Certainly! Our study, which analyzed data from the Insight 46 study, followed over 5,000 individuals since their birth in 1946. We focused on 468 participants aged 70, examining their exercise habits over three decades and analyzing brain scans. The results were very clear: regular exercise throughout life was linked to better cognitive function at age 70,even in those with early signs of Alzheimer’s disease,such as amyloid buildup. Interestingly, this benefit was more pronounced in women.
Archyde: That’s remarkable. Can you explain how exercise impacts the brain in a way that could prevent dementia?
Dr. James: The hippocampus is a really vital part of the brain, and we’re showing that it’s actually larger in those who exercise regularly. 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. It appears that exercise helps protect this region, allowing it to maintain its size and function even as we age.
Archyde: Do you have any insights into why this effect might be stronger in women?
Dr.James: That’s a great question, and one we are actively exploring. There could be several factors involved, such as hormonal differences, lifestyle factors, or even genetic predispositions. More research is needed to unravel this specific link.
Archyde: What types of exercise do you recommend to maximize these brain-boosting benefits?
Dr. James: while more research is needed to pinpoint the exact mechanisms, the data suggests that engaging in regular physical activity throughout adulthood is crucial. This can include activities like brisk walking, swimming, cycling, or even dancing – anything that gets you moving and elevates your heart rate.
Archyde: This is incredibly encouraging news.What message would you give to people who are concerned about dementia or who simply want to keep their brains healthy as they age?
Dr. James: It’s never too late, it’s never too early. People who are active, it’s really good for your brain. even if you are later in life, even starting to have disease symptoms, it could still be beneficial. Think of exercise not just as physical fitness, but as a powerful tool for maintaining cognitive health and possibly delaying the onset of dementia.
