The 2026 Buenos Aires Neurology Summit highlighted how structured multidomain routines and risk factor management may help delay cognitive decline after 60.
On September 16 and 17, 2026, the Alzheimer’s Association and the World Dementia Council hosted the Brain Health and Cognition in Latin America meeting in Buenos Aires. The event brought together more than 100 physicians, researchers and health-system representatives to evaluate how modifying daily habits could alter the progression of cognitive decline.
A central point of discussion at the meeting involved population-level risk analysis. Experts cited data suggesting that addressing modifiable risk factors could potentially prevent or delay up to 45 percent of dementia cases worldwide. This global figure originates from the 2024 Lancet Commission, which assessed 14 modifiable risk factors.
These factors include high blood pressure, physical inactivity, untreated vision loss and hearing loss. The assessment also identified high LDL cholesterol, obesity, smoking and type 2 diabetes as critical elements. Furthermore, the commission highlighted excessive alcohol consumption, depression, social isolation and traumatic brain injury. Finally, environmental and historical risks like air pollution and limited early education round out the list of fourteen modifiable factors.
Coverage of the Buenos Aires meeting also reported regional estimates that differ from the global average. Attendees discussed estimates of up to 54 percent for Latin America and up to 60 percent for Argentina. These discussions highlighted the urgent need to address lifestyle and environmental variables across different communities. The conference sought to translate this scientific evidence into practical programs that regional health systems can actually implement.
The summit focused heavily on the LatAm-FINGERS trial, which was published in The Lancet and funded by the Alzheimer’s Association. This study was described as the first randomized multicenter clinical trial in Latin America focused on preventing cognitive decline. It followed 1,065 adults aged 60 to 77 across 11 Latin American countries and 12 research sites for a period of two years.
The Buenos Aires event followed the publication and presentation of these LatAm-FINGERS results in 2026. This timing makes the trial a highly relevant regional development in dementia prevention research. LatAm-FINGERS is particularly significant because earlier multidomain prevention research was not designed specifically around the social, healthcare and cultural conditions of Latin America. The intervention model resembles the broader FINGER approach, where multiple risk factors are addressed together.
Participants who received a structured, multidomain intervention achieved 55 percent greater improvement in global cognition than those who received only general health advice. The structured program combined physical activity, healthy eating and cardiovascular-risk management. It also incorporated cognitive training and social engagement.
Infobae reported that improvements were also observed in memory, processing speed and executive function. These specific abilities are deeply involved in planning, decision-making and responding efficiently to everyday problems. Rather than testing a single intervention in isolation, researchers evaluated how these multiple protective behaviors worked together within a comprehensive framework. The researchers recognized that older adults rarely face a single health challenge, so an intervention must address multiple domains simultaneously.
These findings shift the focus of brain health away from isolated memory exercises and toward comprehensive lifestyle integration. For adults over 60, cardiovascular health is now clearly established as a primary component of cognitive protection. Managing blood pressure, treating diabetes and lowering cholesterol are practical medical steps that directly support brain function over time. Treating these vascular conditions is no longer just about heart health, as it forms a critical pillar of cognitive preservation.
The research also reinforces the importance of structure and professional guidance. The trial demonstrated that a coordinated program outperformed general health advice. This aligns with current World Health Organization guidance, which supports tailored multidomain interventions alongside the management of medical conditions. The WHO guidance explicitly applies to adults without dementia, including people with normal cognition or mild cognitive impairment.
The framework also emphasizes that risk factors span the life course, with conditions like hypertension, diabetes and social isolation remaining highly relevant in later life. WHO guidelines also support the reduction of environmental risks alongside individual behavioral changes. While some factors like education begin early in life, physical inactivity and hypertension remain critical during midlife and later life.
If you want to protect your brain, building a consistent routine that includes movement, social connection and regular checkups is more effective than adopting a single new habit. The LatAm-FINGERS trial included social engagement as a formal part of the intervention rather than an optional extra. Deliberately protecting your social connections can provide meaningful cognitive benefits. Maintaining strong relationships, participating in group activities and staying engaged with your community are active forms of cognitive support.
Addressing sensory health is another immediate priority supported by the recent Lancet Commission assessment. Managing hearing loss and treating vision problems are identifiable ways to reduce cognitive strain. The event’s emphasis on implementation highlights that structured coaching, regular assessments and ongoing monitoring are crucial for translating clinical trials into community habits. Finding a structured program that provides gradual support is often more successful than attempting to change every habit overnight.
While the summit provided encouraging data, it is critical to interpret the estimates carefully. The Alzheimer’s Society explicitly notes that there is currently no guaranteed way to prevent dementia. The headline figure of 45 percent represents a population-level estimate of cases that could potentially be prevented or delayed. It is not a personal guarantee that an individual can completely eliminate their own risk through lifestyle changes alone.
Furthermore, the LatAm-FINGERS trial measured improvements in global cognition scores, which is not the same as preventing a clinical dementia diagnosis. The 55 percent greater improvement refers to performance on a composite cognitive measure compared to a control group. This means that participants scored better on a specific set of tests, but it does not mean their brains became immune to future cognitive decline. Expecting a single program to guarantee lifelong memory preservation misrepresents the clinical evidence.
The study specifically enrolled adults aged 60 to 77 who were already at risk of cognitive decline. Because the sample was selected based on specific risk factors, the exact outcomes may not apply uniformly to all older adults. People with advanced dementia or severe medical limitations may experience different results from a multidomain lifestyle intervention. The evidence supports reducing risk and maintaining cognitive function, not guaranteeing that dementia will never occur.
Finally, maintaining multiple behavioral changes requires sustained support and realistic goal setting. A clinical trial can provide scheduled coaching and monitoring, whereas real-world programs must address practical barriers like affordability, transportation and health literacy. The trial provided structured guidance over two years, showing that ongoing accountability is often necessary for success. It is unreasonable to expect that adopting these habits will produce immediate improvements in daily memory function without long-term dedication.
The developments presented in Buenos Aires confirm that cognitive longevity depends on a combination of medical care, physical movement and social integration. Research continues to prove that our brains do not age in isolation from our cardiovascular systems or our environments. Cognitive protection requires a multifaceted approach that addresses physical activity, nutrition, cognitive training and vascular health simultaneously.
While we cannot control every aspect of aging, adopting a structured, multidomain approach offers a practical and evidence-based path forward. Treating common conditions like high cholesterol or hearing loss provides measurable benefits for the aging brain. Moving away from isolated quick fixes allows older adults to focus on proven, sustainable strategies that fit their daily lives. The summit's goal was precisely to consider how this evidence could become practical policy for diverse populations.
By focusing on manageable habits and working closely with healthcare providers, you can take meaningful steps to protect your long-term cognitive health. Finding culturally appropriate, community-based support makes it much easier to maintain these habits over the years. The shift toward multidomain interventions marks a significant improvement in how we understand and manage cognitive aging.
