In the fall of 2024, the GECC hosted a series of town hall meetings
with nearly 300 unique participants from 130 organizations across 21
countries. These meetings yielded critical insights that will guide
the GECC’s efforts over the next five years. These insights will help
prioritize research areas where the GECC will create new resources and
tools for researchers studying the exposome and its impact on brain
health.
The GECC’s first town hall meetings on October 9th were a
resounding success, bringing together 127 participants from 64
organizations across 13 countries to generate insights on the
influences of brain health as people.

There were many shared themes across the town halls that were salient
to all GECC domains. Three of the most resounding, overarching themes
were (1) interdisciplinary collaboration,
(2) innovative methodologies, and (3)
development of novel measures.
In addition to these shared takeaways, each domain identified key
areas of focus for their future research.
Life-course education and work-related policies: Policies that shape
access
to education and lifelong
learning opportunities influence cognitive development and
resilience against neurodegeneration. Additionally, policies
promoting cognitively stimulating work environments, such as
those encouraging occupational complexity, may help reduce
Alzheimer’s disease risk.
Policies on Loneliness and Social Isolation: Loneliness and social
isolation are linked to cognitive
decline. Research in the policy domain will focus on
policies that foster community engagement, such as promoting
third spaces (e.g., community centers), improving digital
literacy, and implementing social initiatives to connect
individuals to local activities.
Caregiving and Long-Term Care policies: Policies affecting formal
long-term
care eligibility,
respite services, and caregiver training shape the quality
and accessibility of care for aging populations, influencing
Alzheimer’s disease risk and resilience.
Community and Connection: Strong social networks and community support
systems reduce
social isolation and enhance cognitive resilience. Research
will focus on how different types of relationships—family,
friends, and community ties—impact Alzheimer’s disease risk
and protective factors, as well as how interventions can
strengthen these networks across different life stages.
Spatial and Structural Considerations: Neighborhood characteristics such
as
safety, walkability,
and access to social spaces shape daily experiences and
influence exposure to risk or protective factors for
cognitive health. Research will examine how geographic
disparities and built environment variations contribute to
Alzheimer’s disease resilience.
Workplace Environment: Employment settings function as significant social
environments. Research will explore how workplace dynamics,
job stability, and social interactions at work affect brain
health over the life course, including the role of workplace
policies in mitigating stress and fostering cognitive
engagement.
Access to Resources: Different
levels of access to care services, physical activity
programs, and social engagement opportunities may contribute
to differences in Alzheimer’s disease risk across
populations. Research will assess how economic and political
factors shape service availability and use.
Early Life Exposures: Educational and occupational experiences, along
with
caregiving roles, shape access to and use of community
services, impacting cognitive health outcomes. Research will
investigate how early-life exposure to support systems
influences long-term cognitive resilience.
Urban vs. Rural Disparities:
Research will examine how differences in community service
availability between urban and rural settings influence
brain health. Particular attention should be given to how
infrastructure, transportation, and healthcare access create
barriers or opportunities for dementia risk reduction.
Air Quality: Exposure to air
pollution, including particulate matter and toxic chemicals,
has been linked to neuroinflammation and cognitive decline.
Research will refine exposure assessments, identify the most
harmful pollutants, and develop guidance for reducing
exposure in high-risk communities.
Green Spaces: Access to parks,
tree-lined streets, and biodiversity-rich environments
promotes cognitive and emotional well-being through stress
reduction, increased physical activity, and social
engagement. Research will develop standardized indicators of
greenspace quality and accessibility to optimize health
benefits and evaluate the effectiveness of urban greening
initiatives.
Neighborhood Characteristics: Urban planning can promote active
lifestyles
and social
interaction, both protective against Alzheimer’s disease.
Research will define the core features of healthy
neighborhoods, including transportation access, noise
pollution, and proximity to essential services, while
considering how extreme weather and cultural factors influence their
effectiveness.
Education, Work, and Status: Formal education as well as factors like
literacy,
numeracy, and access to lifelong learning opportunities
could reduce ADRD risk. In addition, employment precarity,
job characteristics, and caregiving responsibilities dimpact
health, social ties, and economic well-being.
Health Behaviors: Physical
activity, diet, substance use, sleep, and social engagement
can reduce Alzheimer’s risk.
Social Relationships: Engaging
with friends, family, and one’s community are critical for
well-being and protective against dementia. They are also
the foundation of a caregiving network when one’s physical
and cognitive health declines.
Subjective Well-Being:
Individuals experience a variety of emotions in their lives
- sustained negative emotions, such as stress, depression,
and loneliness, have the potential to increase dementia risk
and fragility.
Extreme Weather Events: Acute
extreme weather events (e.g., wildfires, floods, heat waves) and
their cumulative effects on mental and physical health
require further study. Research should examine how exposure
to these events influences stress, inflammation, and
cognitive decline over time.
Localized Risks and Population Vulnerabilities: extreme weather impacts
vary
across populations. Research
will identify vulnerable groups, such as older adults with
pre-existing health conditions, and assess long-term
cognitive effects of different extreme weather exposures, including
prolonged heat stress and poor air quality.
Integrated Research Approaches: Addressing extreme weather-related health risks
necessitates
multidisciplinary collaboration, global exposure metrics,
and community-specific interventions. Research will
prioritize developing frameworks for integrating extreme weather
adaptation strategies into public health planning.
Advancing Measurement in Life Course Research: Innovative methodologies
are
needed to accurately measure
cumulative exposures and Alzheimer’s disease outcomes.
Research will focus on developing longitudinal tracking
systems to better understand lifetime risk factors.
Measuring Cross-Domain Interactions: Investigating how social, physical,
and economic factors
interact will deepen understanding of Alzheimer’s disease
risk and resilience. Research will develop computational
models to capture the complexity of these interconnections.
Harmonization: Standardizing
methodologies across cohorts and countries will improve data
comparability and facilitate research collaboration,
ensuring that findings can inform policy and other
healthcare intervention strategies globally.
The town halls allowed participants the opportunity to discuss what is
most important to them. Hosted virtually on Zoom, participants began
by suggesting key factors that may influence our communities’ risk of,
resilience to, and disparities in Alzheimer’s and dementia. Breakout
sessions then formed around these topics for participants to have
focused discussions. Collaborative notes were taken so that these
discussions will help guide participants and the GECC to set
priorities for future scientific research and policies related to
brain health.
Will More GECC Town Halls Be Done in the Future?
The GECC will host another round of town hall meetings in October to December 2026 to review progress on our initial priorities and identify any new priorities that have arisen in the interim.
