Members of the International Alliance on Brain Health at the second meeting April 24-25 in Buenos Aires.
The second meeting of the International Alliance on Brain Health (IABH), held April 24-25, 2026, in Buenos Aires, Argentina, convened an extraordinary international community of neurologists, psychiatrists, neuroscientists, rehabilitation experts, public health leaders, and policymakers from five continents. Organized jointly by the Swiss Brain Health Foundation and the Institute of Cognitive Neurology (INECO) Foundation, the meeting emerged as one of the largest multidisciplinary forums dedicated to brain health to date.
More than a scientific congress, the gathering reflected a growing international recognition that brain health represents one of the defining medical, societal, and economic challenges of the 21st century. Across disciplines and regions, participants shared a common conviction: protecting the brain requires new forms of coordination capable of bridging conventional boundaries between neurology, psychiatry, rehabilitation, and public health.

The meeting was held under the patronage of the World Federation of Neurology (WFN) and the World Psychiatric Association (WPA). The WFN’s prominent role underscored its expanding leadership in international brain health advocacy and its commitment to fostering connected approaches to neurological and mental health worldwide.
The Buenos Aires meeting coincided with the 20th anniversary of the INECO Foundation and followed significant legislative initiatives in Argentina aimed at developing one of Latin America’s first comprehensive national frameworks for brain health and dementia prevention. Interest in the event was remarkable: More than 1,000 participants preregistered, including 359 in-person attendees and hundreds of virtual participants representing 24 countries from five continents. Forty-five internationally recognized speakers contributed to the scientific program.
WFN Leadership and a New Era of Collaboration

Prof. Claudio L.A. Bassetti discusses the Swiss Brain Health Plan at the IABH meeting.
The WFN was prominently represented throughout the meeting. WFN President Prof. Steven Lewis joined leaders from the WPA, the American Academy of Neurology, the European Academy of Neurology, the European Psychiatric Association, the Alzheimer’s Association, the American Heart Association, and the World Health Organization (WHO).
The IABH, formally established in 2025 with support from the Swiss Brain Health Foundation and under the patronage of the WFN and WPA, represents both a symbolic and practical step toward closer alignment between neurology and psychiatry. As emphasized in the alliance’s founding document, the initiative seeks to bridge historical divides between the “two most influential brain health organizations” and promote a unified international vision for brain health.
Throughout the meeting, speakers stressed that neurological and psychiatric disorders share biological, social, and environmental determinants, and therefore require coordinated responses. Neurologists, psychiatrists, rehabilitation specialists, primary care physicians, and public health experts were encouraged to work within a shared model focused not only on disease treatment, but also on prevention, resilience, and lifelong well-being.
This perspective strongly resonates with the WFN’s longstanding mission to improve neurological care, education, and public awareness through international engagement and advocacy.
Brain Health as a Global Imperative

A central message from the IABH discussions was that brain health extends far beyond the absence of disease. Protecting the brain means preserving cognition, emotional well-being, autonomy, productivity, and quality of life throughout the lifespan.
Participants emphasized that neurological and psychiatric disorders now constitute one of the leading causes of disability worldwide, generating immense personal, societal, and economic burdens. In this context, brain health is increasingly understood not only as a medical issue, but also as a strategic societal priority.
Several sessions focused on modifiable risk factors, including hypertension, diabetes, obesity, physical inactivity, sleep disorders, social isolation, and limited educational opportunities. Sessions also covered dementia risk reduction and the growing evidence supporting early, personalized, and multidomain interventions aimed at delaying cognitive decline.
One of the meeting’s recurring themes was the recognition that “heart health is brain health.” Speakers highlighted the profound interconnection between vascular health and cognitive outcomes, calling for stronger links between cardiovascular medicine and brain health communities. This integrated perspective reflects a growing recognition that effective prevention strategies must consider brain health within the broader context of systemic health.
Regional Perspectives and Reciprocal Learning

Top brain health experts discussed technology, equity, brain health indicators, governance, and more during an IABH roundtable.
One of the defining characteristics of the meeting was its emphasis on models of reverse innovation — understood not as one-way transfer, but as a form of reciprocal learning between high-income countries and low- and middle-income regions.
Innovation in brain health does not flow exclusively from resource-rich settings, according to participants. Discussions emphasized a broader model of bidirectional exchange and reciprocal learning between health care systems across different regions and economic contexts. Many effective community-based interventions, prevention strategies, and models of care emerge precisely from settings where resources are limited and creativity becomes essential.
The program showcased initiatives from Africa, Asia, Europe, Latin America, and North America, highlighting national and regional strategies aimed at advancing policy, prevention, and care across diverse health care systems.
Within this international landscape, the WFN’s longstanding relationships with regional neurological societies position the federation as a natural platform for international exchange. Discussions repeatedly emphasized the importance of adapting strategies to local cultural, economic, and health care realities while maintaining shared objectives.
Artificial Intelligence, Sleep, and the Future of Brain Health

The scientific program also explored emerging technologies and future directions in research and care. Sessions examined the growing role of artificial intelligence (AI), multimodal data integration, digital biomarkers, and precision medicine approaches capable of improving risk prediction and enabling earlier interventions.
Another major topic was sleep health, increasingly recognized as a fundamental pillar of brain health alongside nutrition and physical activity. Speakers reviewed mounting evidence linking sleep and circadian regulation to neurological, psychiatric, cardiovascular, and neurodegenerative outcomes, reinforcing the idea that brain health must be approached through multidimensional and preventive perspectives.
The meeting concluded with the presentation of 10 implementation strategies designed to translate international commitments into concrete action. These recommendations included:
- Strengthening advocacy initiatives
- Embedding brain health into legal and economic frameworks
- Expanding workforce education
- Improving public communication
- Accelerating the integration of research findings into routine clinical care
Looking Ahead

The meeting marked an important milestone in the consolidation of the IABH and highlighted the growing momentum surrounding brain health policy and advocacy.
For the WFN, the event reflected an evolving role that extends beyond representing neurologists worldwide. Increasingly, the federation is emerging as an international advocate for connected brain health strategies linking disciplines, regions, and health care systems.
By supporting initiatives such as the IABH, the WFN continues to foster international cooperation while advancing its broader mission of improving neurological care, education, and brain health worldwide.
The conversations initiated in Buenos Aires are expected to continue through future alliance meetings and collaborative projects involving stakeholders across the neurological and mental health communities. The next IABH meeting will take place Nov. 25-26, 2026, in Rome, followed by a 2027 meeting in Singapore, further expanding the alliance’s international reach and implementation agenda.
Building on the Bern Declaration on Brain Health developed during the 2025 founding meeting in Bern, the alliance is also advancing collaborative publications and strategic initiatives aimed at strengthening integrated global brain health policies and partnerships. Together, these efforts reinforce the idea that brain health, perhaps more than any other field in medicine, demands collective thinking beyond borders. •
