According to Gram Research analysis, a 12-month randomized controlled trial of 198 adults with mild cognitive impairment found that increasing daily steps to 10,000 produced small improvements in memory and thinking skills compared to maintaining normal activity levels. Participants who walked more showed measurable improvements in spatial working memory and overall cognitive scores, though the gains were modest. However, the study found no significant changes in brain volume, body composition, or blood markers related to brain health, suggesting that while walking helps memory slightly, it’s not a complete solution for cognitive decline.
A new study followed nearly 200 people over one year to see if walking more steps each day could help their thinking and memory skills. People with mild cognitive impairment, a condition where memory and thinking start to slip, were split into two groups. One group tried to walk 10,000 steps daily while the other kept their normal activity. Researchers tracked their steps with wristbands and tested their memory and brain health. The results showed that people who walked more did improve slightly on memory tests, but the changes were small. The study found no major changes in brain size or body weight, suggesting that while walking helps a little, it’s not a complete solution for memory problems.
Key Statistics
A 12-month randomized controlled trial published in Frontiers in Aging Neuroscience in 2026 involving 198 adults with mild cognitive impairment found that those who increased their daily steps by 1,728 steps showed measurable improvements in spatial working memory compared to those who maintained normal activity.
In the 2026 trial of 198 participants with mild cognitive impairment, the walking intervention group showed improvements in Montreal Cognitive Assessment scores, though researchers described the changes as modest and noted that broader cognitive test results were mixed.
A 2026 study of 188 adults who completed a 12-month walking intervention found small reductions in waist circumference (1 centimeter) and hip circumference (1 centimeter), but no significant changes in body weight, brain volume, or blood markers related to metabolism and brain health.
The Quick Take
- What they studied: Whether walking more steps each day could improve memory and thinking skills in people with mild cognitive impairment, a condition where memory starts to decline but daily life isn’t severely affected.
- Who participated: 198 adults aged 50 to 70 years old with mild cognitive impairment who owned smartphones. Most were white and lived in their own homes. 188 people finished the full 12-month study.
- Key finding: People who increased their daily steps to 10,000 showed small improvements in memory tests compared to those who stayed at their normal activity level. The improvement was modest but measurable, with differences in spatial working memory errors and overall cognitive scores.
- What it means for you: If you’re experiencing early memory problems, walking more may help slow or slightly improve memory decline. However, this study shows walking alone isn’t a complete fix. It works best as part of a broader approach to brain health that includes other activities and healthy habits. Talk to your doctor about what’s right for you.
The Research Details
This was a randomized controlled trial, which is the gold standard for testing whether something actually works. Researchers randomly assigned 198 people into two groups: one group aimed to walk at least 10,000 steps daily, while the other group continued their normal activity habits. Everyone wore wristbands that tracked their steps for the entire 12 months. The researchers tested everyone’s memory and thinking skills at the start and end using standard brain tests. They also measured brain size, body measurements, and blood markers that show brain and heart health.
The study was carefully designed to be fair to both groups. The intervention group didn’t get personalized coaching or targets based on their starting fitness level, just a simple goal of 10,000 steps. This makes the results more realistic for everyday people, since it shows what happens with a straightforward walking goal rather than a customized program.
Long-term studies like this are important because they show what actually happens when people try to change their habits over many months. Most previous research on walking and brain health was shorter or didn’t carefully track activity. This study used wristbands to measure real steps, not just ask people to remember how much they walked. This gives more accurate information about whether the walking actually happened and what effect it had.
This study is well-designed with several strengths. It randomly assigned people to groups, which reduces bias. It tracked activity objectively with wristbands rather than relying on memory. It lasted a full year, long enough to see real changes. However, all participants were 50 to 70 years old and mostly white, so results may not apply to younger people or other ethnic groups. The study also only included people with smartphones and moderate baseline activity, so results may differ for less active people or those without technology access.
What the Results Show
The intervention group successfully increased their daily steps by about 1,728 more steps per day compared to the control group, showing that the walking goal was achievable and people stuck with it. On the Montreal Cognitive Assessment, a standard memory test, the walking group showed small improvements in their scores compared to the control group. The most notable finding was in spatial working memory, a type of memory used for holding and manipulating information, where the walking group made fewer errors.
However, the improvements were modest. The researchers described them as small changes, not dramatic transformations. When they looked at the broader battery of cognitive tests, the results were mixed and less clear. Some tests showed benefits while others didn’t, suggesting the effect of walking on thinking skills is real but limited.
Interestingly, the study found no significant changes in brain volume, meaning the walking didn’t appear to grow brain tissue. There were also no meaningful changes in body composition, weight, or blood markers related to brain health and metabolism. This suggests that while walking helped memory slightly, it didn’t produce the major physical changes researchers might have expected.
The study did find small reductions in waist and hip circumference in the walking group, about 1 centimeter each. While these measurements were statistically significant, they’re so small they’re unlikely to be noticeable in daily life. No changes were found in body weight, fat percentage, or other measures of body composition. Blood tests measuring inflammation, metabolism, and markers of brain degeneration showed no differences between groups. This suggests that the walking’s benefit to memory doesn’t come from major changes to body weight or metabolism.
Previous research has shown that physical activity is generally good for brain health and memory. This study confirms that walking does help with memory in people with mild cognitive impairment, but the effect is smaller than some earlier studies suggested. The finding that walking didn’t change brain volume is somewhat surprising, since some previous research suggested exercise could grow brain tissue. This study’s careful 12-month tracking with wristbands provides more reliable evidence than earlier studies that relied on people reporting their activity from memory.
The study only included people aged 50 to 70, mostly white, who owned smartphones and already had moderate activity levels. Results may not apply to younger or older people, other ethnic groups, or people who are very sedentary. The study didn’t compare walking to other types of exercise like strength training or dancing, so we don’t know if walking is better or worse than alternatives. The improvements in memory, while real, were small enough that they might not make a noticeable difference in daily life. Finally, the study only looked at people with mild cognitive impairment, not people with normal memory or advanced dementia.
The Bottom Line
If you have mild cognitive impairment or are concerned about memory decline, increasing your daily steps to 10,000 appears to help slightly with memory and thinking skills. This is a low-risk activity that most people can do. However, walking alone is not a complete solution. Combine it with other brain-healthy habits like social engagement, mental challenges, healthy eating, and quality sleep. Talk to your doctor before starting a new exercise program, especially if you have health conditions. Moderate confidence: the study shows real but small benefits.
This research is most relevant for people aged 50 to 70 who have noticed early memory problems or have been diagnosed with mild cognitive impairment. It’s also useful for family members and caregivers looking for ways to support brain health. People with normal memory may still benefit from walking for overall health, but this study doesn’t specifically address them. People with advanced dementia or severe mobility issues should talk to their doctor about appropriate activity levels.
The study lasted 12 months, and improvements in memory were measurable over this timeframe. You shouldn’t expect overnight changes. If you start a walking program, give it at least several months to see if it helps your memory and thinking. Benefits may continue to build over time, but this study didn’t look beyond 12 months, so we don’t know about longer-term effects.
Frequently Asked Questions
Does walking 10,000 steps a day improve memory in people with mild cognitive impairment?
Research shows that increasing daily steps to 10,000 produces small improvements in memory and thinking skills in people with mild cognitive impairment. A 2026 trial of 198 adults found measurable gains in spatial working memory, though the improvements were modest and not transformative.
How long does it take to see memory improvements from walking more?
The study tracked participants for 12 months and found measurable memory improvements over this timeframe. You shouldn’t expect immediate changes. Give a walking program at least several months to show benefits, and continue for a full year to see the effects demonstrated in this research.
Can walking help prevent brain shrinkage or dementia?
This study found no significant changes in brain volume from walking, so it doesn’t appear to prevent brain shrinkage. Walking may help slow memory decline slightly, but it’s not a complete prevention strategy. Combine it with other brain-healthy habits like social engagement, mental challenges, and quality sleep.
Is 10,000 steps a day necessary for memory benefits?
This study specifically tested a 10,000-step goal and found benefits at that level. The research doesn’t tell us whether fewer steps would help or if more steps would help more. Talk to your doctor about a walking goal that’s realistic and safe for your fitness level.
Who should try this walking program for memory improvement?
This research applies to adults aged 50 to 70 with mild cognitive impairment or early memory problems. If you’re younger, older, or have normal memory, results may differ. Always consult your doctor before starting a new exercise program, especially if you have health conditions.
