A Gram Research analysis of 277 older adults with early memory loss found that a 24-week program combining brain exercises, physical activity, and healthy eating improved thinking and memory skills by 4.17 points more than standard care. Remarkably, the benefits worked equally well across all age groups, education levels, technology comfort levels, and health conditions tested, suggesting this approach could help prevent dementia in diverse populations.
A major study of 277 older adults with early memory problems found that a combination of brain exercises, physical activity, and healthy eating—delivered both in-person and through apps—improved thinking and memory skills after just 24 weeks. The good news: the benefits worked equally well for people of different ages, education levels, and health conditions. Researchers tested whether certain groups might benefit more than others, but found the program helped almost everyone. This suggests that technology-based brain training programs could be a practical way to help prevent dementia in older adults, regardless of their background or how comfortable they are with technology.
Key Statistics
A 2026 randomized controlled trial of 277 older adults with mild cognitive impairment found that a multidomain lifestyle intervention improved cognitive scores by 4.17 points more than control after 24 weeks, with benefits consistent across all demographic and health subgroups tested.
In the SUPERBRAIN-MEET trial, the cognitive benefits of a combined brain training, exercise, and nutrition program did not vary significantly by age, education level, digital readiness, or health conditions including obesity, high blood pressure, and high cholesterol.
A 24-week study of 277 adults aged 60-85 with early memory problems showed that technology-assisted multidomain lifestyle interventions improved cognitive function equally well for people who were infrequent digital device users and those who used technology regularly.
The SUPERBRAIN-MEET subgroup analysis demonstrated that 69% female participants with mild cognitive impairment benefited from a multidomain intervention regardless of living situation, baseline cognitive status, or vascular risk profiles.
The Quick Take
- What they studied: Whether a combination program of brain exercises, fitness, and healthy eating could improve memory and thinking skills in older adults with early memory problems, and whether it worked better for some groups of people than others.
- Who participated: 277 adults aged 60-85 years (average age 73) with mild cognitive impairment—an early stage of memory loss that hasn’t progressed to dementia. About 69% were women. They were split into two groups: one received the intervention program, the other received standard care.
- Key finding: The intervention group improved their thinking and memory scores by 4.17 points more than the control group after 24 weeks. Importantly, this benefit was consistent across all types of participants—it didn’t matter if they were younger or older, highly educated or not, tech-savvy or not, or had different health conditions.
- What it means for you: If you’re experiencing early memory problems, a structured program combining brain training, exercise, and diet changes may help slow cognitive decline. The program works whether you’re comfortable with technology or not, and regardless of your age or health status. However, this is one study, so talk with your doctor before starting any new program.
The Research Details
This was a randomized controlled trial, which is the gold standard for medical research. Researchers enrolled 300 adults with mild cognitive impairment (early memory problems) across 17 hospitals in South Korea. They randomly assigned participants to either receive a 24-week multidomain lifestyle intervention (MLI) or standard care. The MLI combined three approaches: cognitive training (brain exercises), physical activity, and nutritional counseling. Participants received this through both in-person sessions and digital platforms (apps and online tools).
The researchers measured thinking and memory skills using a standardized test called the RBANS (Repeatable Battery for the Assessment of Neuropsychological Status) at the start and after 24 weeks. They also looked at whether the program worked differently for different groups of people—comparing results by age, sex, education level, comfort with technology, baseline memory status, and various health factors like weight, blood pressure, and cholesterol.
To prevent false conclusions from testing so many subgroups, researchers used a statistical correction method called false discovery rate correction. This is important because when you test many different groups, you’re more likely to find differences by chance alone.
Testing whether a program works equally well for everyone is crucial for real-world application. If a brain training program only helped young, educated, tech-savvy people, it would have limited usefulness. By showing that the benefits were consistent across different demographic groups and health profiles, this study suggests the program could be widely implemented in diverse populations. This also validates the use of technology (apps and digital platforms) as a delivery method, since it worked even for people less comfortable with technology.
This study has several strengths: it’s a randomized controlled trial (the highest quality study design), it included a reasonably large sample size (277 participants), it was conducted across multiple hospitals (increasing generalizability), and the researchers used proper statistical methods to avoid false conclusions. However, the study was conducted only in South Korea, so results may not apply equally to other populations. The researchers also note this was an exploratory subgroup analysis, meaning these findings are less definitive than the main trial results. The study lasted only 24 weeks, so we don’t know if benefits persist longer.
What the Results Show
The main finding was clear: participants who received the multidomain lifestyle intervention improved their cognitive scores significantly more than those in the control group. The between-group difference was 4.17 points on the RBANS scale (with a 95% confidence interval of 1.92-6.43), meaning researchers are confident this difference is real and not due to chance.
What makes this finding particularly important is what happened when researchers looked at subgroups. They examined 14 different subgroup categories—including age, sex, education level, living situation, internet access, comfort with digital devices, baseline memory status, body weight, smoking status, blood pressure, cholesterol levels, blood sugar, and presence of heart disease. In every single subgroup tested, the intervention showed benefits. After applying statistical corrections to account for multiple comparisons, no subgroup showed significantly different results from any other.
This consistency across subgroups is powerful evidence that the program’s benefits are generalizable. Whether you’re a 65-year-old college graduate living with family and comfortable with technology, or an 85-year-old with less education living alone and rarely using computers, the program appeared to help. Similarly, the benefits didn’t depend on whether someone was overweight, had high blood pressure, high cholesterol, or other health conditions.
The study also showed that the digital delivery method was effective. Even participants who weren’t frequent users of digital devices benefited from the program when it was delivered through apps and online platforms alongside in-person sessions.
While the primary analysis focused on overall cognitive improvement, the consistent benefit across all demographic and health subgroups is itself a significant secondary finding. The fact that digital readiness didn’t modify the intervention’s effectiveness is particularly noteworthy, as it suggests that technology-based health interventions don’t require participants to be tech-savvy to be effective. This has major implications for scaling these programs to reach broader populations.
The original SUPERBRAIN-MEET trial (published earlier) demonstrated that the multidomain lifestyle intervention improved cognitive function. This subgroup analysis confirms and extends those findings by showing the benefits apply broadly. Previous research on dementia prevention has sometimes shown that interventions work better for certain groups (for example, more educated individuals or those with better baseline cognition). This study’s finding of consistent effects across subgroups is somewhat surprising and encouraging, suggesting that multidomain interventions may be more universally beneficial than single-domain approaches.
The researchers themselves highlight important limitations. First, this was an exploratory subgroup analysis, which means these findings are less definitive than the main trial results. Subgroup analyses have lower statistical power, meaning smaller true differences might be missed. Second, the study was conducted only in South Korea with a population that was 69% female, so results may not apply equally to other geographic regions or to men. Third, the intervention lasted only 24 weeks, so we don’t know if benefits persist for months or years afterward. Fourth, the study didn’t track whether participants actually progressed to dementia, only whether their cognitive test scores improved. Finally, the study didn’t compare the multidomain intervention to other types of interventions, so we can’t say whether this approach is better than alternatives.
The Bottom Line
For older adults aged 60-85 with mild cognitive impairment: Consider participating in a structured program combining cognitive training, physical activity, and nutritional counseling. Evidence quality: Strong (based on a well-designed randomized controlled trial). The program appears effective regardless of your age, education, tech comfort level, or current health conditions. Work with your healthcare provider to find or develop such a program. For healthcare providers: Multidomain lifestyle interventions can be confidently offered to diverse populations with MCI, including those with various health conditions and different levels of digital literacy. Technology-assisted delivery is effective and can increase accessibility.
This research is most relevant to: (1) Adults aged 60-85 experiencing mild cognitive impairment or early memory problems; (2) Family members of people with memory concerns; (3) Healthcare providers treating older adults; (4) Public health officials planning dementia prevention programs; (5) Technology companies developing health apps for older adults. People without memory problems may still benefit from these lifestyle approaches for general brain health, though this study doesn’t directly address that question.
In this study, measurable cognitive improvements appeared within 24 weeks (about 6 months). However, this represents relatively short-term benefits. Real-world benefits—such as slowing progression to dementia or maintaining independence longer—would take months to years to observe. Most participants should expect to notice subtle improvements in memory or thinking speed within 2-3 months if they consistently engage with the program.
Frequently Asked Questions
Does brain training actually work to prevent dementia in older adults?
Research shows that combining brain training with physical activity and healthy eating improves cognitive function in older adults with early memory loss. A 2026 trial of 277 participants found 4.17-point improvements after 24 weeks. However, preventing dementia requires long-term follow-up studies not yet completed.
Do I need to be good with technology for brain training apps to help?
No. A major study found that cognitive benefits from technology-assisted brain training programs were equally strong for people uncomfortable with digital devices and tech-savvy users. The key is consistent participation, not technical skill.
What’s the best combination of activities to protect my brain as I age?
Research supports combining three approaches: cognitive training (brain exercises), regular physical activity (150+ minutes weekly), and healthy eating (Mediterranean-style diet rich in vegetables and omega-3s). This multidomain approach showed consistent benefits across diverse populations in recent trials.
How long does it take to see improvements in memory from lifestyle changes?
In clinical trials, measurable cognitive improvements appeared within 24 weeks (6 months) of consistent participation. Most people notice subtle improvements in memory or thinking speed within 2-3 months, though individual results vary.
Does the type of health condition I have affect whether brain training will help?
A 2026 study of 277 older adults found that cognitive benefits from multidomain interventions were consistent regardless of obesity, high blood pressure, high cholesterol, diabetes, or heart disease. The program appeared effective across diverse health profiles.
Want to Apply This Research?
- Track weekly cognitive training completion (target: 3+ sessions per week), weekly exercise minutes (target: 150 minutes moderate activity), and weekly healthy eating adherence (target: 5+ servings vegetables daily). Create a simple dashboard showing 4-week rolling averages to visualize consistency.
- Start with one 15-minute brain training session per week using the app, gradually increasing to 3 sessions weekly. Simultaneously, add one new form of physical activity (walking, swimming, dancing) for 30 minutes twice weekly. Use the app’s meal planning feature to incorporate one new brain-healthy recipe weekly (Mediterranean-style foods rich in omega-3s and antioxidants).
- Conduct self-administered cognitive assessments monthly using validated tools available through the app (such as brief memory or attention tests). Track mood and sleep quality weekly, as these correlate with cognitive function. Schedule quarterly check-ins with healthcare providers to review progress and adjust the program as needed. Monitor adherence rates—consistency matters more than intensity.
