New Brain Health Coalition Launches as Landmark Study Reveals Lifestyle Changes Can Protect Against Cognitive Decline

In a groundbreaking move for public health, the Alzheimer's Association has launched the Brain Health Roundtable, a cross-sector coalition designed to elevate brain health as a national priority. This announcement comes on the heels of transformative results from the U.S. POINTER study, which demonstrates that structured lifestyle interventions can significantly improve cognitive function in older adults at risk of dementia.

A National Coalition for Brain Health

The Brain Health Roundtable brings together leaders from health systems, disease-specific organizations, employer coalitions, public health groups, and industry partners committed to advancing brain health nationwide. Founded members include the American Diabetes Association, National Sleep Foundation, Academy of Nutrition and Dietetics, American College of Preventive Medicine, Eisai, and Eli Lilly and Company.

"The Alzheimer's Association is committed to a future in which brain health is recognized as essential to public health and fully embedded in community programs, clinical care and policy," said Katie Evans, chief programs and mission engagement officer at the Alzheimer's Association.

The coalition will identify shared priorities, align strategies, and translate emerging science on risk reduction into meaningful action through regular convenings, policy briefs, toolkits, and shared metrics to track national impact.

U.S. POINTER Study Delivers Landmark Results

The Roundtable announcement builds upon evidence from the U.S. POINTER (Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk) clinical trial, published in JAMA in July 2025. This two-year, multi-site randomized controlled trial involved 2,111 participants across five U.S. academic centers and health care systems.

The study tested two different lifestyle interventions:

Structured Intervention: Participants attended 38 facilitated peer team meetings over two years with a prescribed program including measurable goals for aerobic exercise (30-35 minutes four times weekly), adherence to the MIND diet, cognitive training three times weekly for 30 minutes using BrainHQ, plus strength and stretching exercises. They also received regular health metric reviews and goal-setting sessions with study clinicians.

Self-Guided Intervention: Participants attended six peer meetings and chose lifestyle changes that suited their preferences and schedules, receiving general encouragement without goal-directed coaching.

Cognitive Benefits Across All Demographics

The results were compelling: both interventions improved cognition in older adults at risk of cognitive decline, but the structured intervention showed greater improvement on global cognition compared to the self-guided approach, protecting cognition from normal age-related decline for up to two years.

Statistically significant differences emerged between groups:

• Global cognitive composite scores increased over time in both groups, with the structured versus self-guided showing 0.029 standard deviation improvement per year (95% CI, 0.008-0.050, P=0.008)
• Executive function z-score increase was greater in structured than self-guided by 0.037 SD per year (95% CI, 0.014-0.060, P=0.003)

Critically, cognitive benefits were consistent across age (mean age 68±5 years), sex (69% female), ethnicity (31% from minoritized ethnoracial groups), heart health status, and apolipoprotein E-e4 genotype—a genetic risk factor for Alzheimer's disease.

"U.S. POINTER is important because it was designed as a rigorous, randomized controlled clinical trial to demonstrate whether an accessible and sustainable lifestyle intervention protects cognitive function in diverse populations in communities across the United States," said Rachel Whitmer, professor in Public Health Sciences and Neurology at UC Davis Health and co-author of the JAMA publication.

The MIND Diet: Mediterranean Meets DASH

A key component of the structured intervention was adherence to the MIND diet—a hybrid approach combining the Mediterranean diet's emphasis on plant-based foods, olive oil, fish, and moderate wine consumption with the DASH diet's (Dietary Approaches to Stop Hypertension) focus on sodium reduction for blood pressure control.

The MIND diet specifically emphasizes:

• Dark leafy greens daily
• Berries twice weekly
• Nuts five times weekly
• Whole grains three times daily
• Olive oil as primary fat
• Fish weekly
• Limited red meat, butter, cheese, pastries, and fried foods

Research cited in the trial indicates that up to 45% of dementia cases globally are attributable to modifiable lifestyle and vascular/metabolic risk factors, including diabetes, midlife hypertension, midlife obesity, physical inactivity, depression, smoking, and low educational attainment.

Public Health Implications Extend Beyond Clinics

The Alzheimer's Association is committing $40 million over the next four years to continue following U.S. POINTER participants through an Alumni Extension study and to bring interventions to communities across America. This investment builds on their nearly $50 million already dedicated to the research, with additional support from the National Institute on Aging at NIH for ancillary studies exploring imaging, vascular measures, sleep, and gut microbiome-related health data.

"As the burden of dementia grows worldwide, U.S. POINTER affirms a vital public health message: healthy behavior has a powerful impact on brain health," noted Maria Carrillo, Ph.D., chief science officer at the Alzheimer's Association. "Positive actions can make a difference in brain health, and when combined into a program that targets multiple factors like diet, exercise, heart health and cognitive engagement, we now know it can have an even more powerful impact."

Implementation Science: Bridging Evidence to Practice

While U.S. POINTER provides the evidence base for what works, translating this into real-world settings requires implementation science—the study of methods to promote the systematic uptake of research findings and evidence-based practices into routine use in communities and health care systems.

Dr. Laura Baker, principal investigator of U.S. POINTER at Wake Forest University School of Medicine, emphasized accessibility: "The potential to improve cognition with fewer resources and lower participant burden is compelling. It highlights that while not everyone has the same access or ability to adhere to more intensive behavior interventions, even modest changes may protect the brain."

The Alzheimer's Association plans to launch several initiatives to support implementation:

• Virtual training programs for healthcare providers
• Community Recognition Program for employers and organizations championing brain health
• Free web-based Brain Health Habit Builder tool allowing individuals to assess current habits and take proactive steps
• 10 Healthy Habits for Your Brain campaign with easy-to-understand strategies

A Multigenerational Approach to Prevention

The research underscores that brain health interventions are relevant across the lifespan. While U.S. POINTER focused on adults aged 60-79 at increased risk of cognitive decline, many lifestyle factors influencing dementia risk begin decades earlier. Midlife hypertension (ages 40-65), midlife obesity, physical inactivity, and educational attainment in young adulthood all contribute to later-life brain health outcomes.

Modeling studies suggest that reducing the prevalence of each modifiable risk factor by just 10% to 20% per decade could lead to an 8% to 15% decline in global Alzheimer's disease prevalence by 2050—a profound public health impact with significant economic implications given the estimated $360 billion annual cost of dementia care in the United States.

Looking Forward: From Research to Action

The Brain Health Roundtable represents a critical bridge between scientific discovery and population-level impact. As Rita Kalyani, M.D., chief scientific and medical officer of the American Diabetes Association and founding Roundtable member, stated: "Collaboration is essential if we want to make meaningful progress in protecting brain health at scale. By bringing together leaders across health care, public health, research and industry, the Roundtable creates a unique opportunity to unify our efforts, strengthen our strategies and ensure that every community benefits from the latest knowledge on risk reduction."

The Alzheimer's Association estimates that 7.2 million older Americans currently live with Alzheimer's dementia—the most common form of dementia—with this number projected to double by 2060 without intervention. Another 5 to 7 million may have mild cognitive impairment due to Alzheimer's disease. The convergence of U.S. POINTER results and the Brain Health Roundtable launch marks a pivotal moment in the national effort to reduce dementia risk through evidence-based lifestyle interventions.
