Equity across the life course matters for brain health

Breaking the barriers: overcoming dementia-related stigma in minority communities

Dementia is a global health concern that affects individuals irrespective of their cultural or linguistic backgrounds. However, research has long recognized the pronounced stigma associated with dementia, particularly within Culturally and Linguistically Diverse (CALD) communities. This article seeks to summarize the underlying factors contributing to the heightened levels of dementia stigma within CALD communities, through a review of the literature. Our examination shows that cultural beliefs, language barriers, limited awareness, and the impact of migration on perceptions of aging and cognitive decline are contributing factors. Consequently, our analysis highlights the need for tailored, culturally appropriate interventions aimed at mitigating stigma and enhancing dementia care within CALD populations. Our proposed solutions, built on a social-ecological approach, highlights the critical role of collaborative efforts involving policymakers, healthcare providers, community organizations, and CALD community members in fostering a more dementia-inclusive society. This perspective piece aims to shed light on the distinct challenges faced by CALD communities, while advocating for a holistic approach to redefine perceptions and care strategies tailored to these populations.

Empathy as a crucial skill in disrupting disparities in global brain health

Brain health refers to the state of a person's brain function across various domains, including cognitive, behavioral and motor functions. Healthy brains are associated with better individual health, increased creativity, and enhanced productivity. A person's brain health is intricately connected to personal, social and environmental factors. Racial, ethnic, and social disparities affect brain health and on the global scale these disparities within and between regions present a hurdle to brain health. To overcome global disparities, greater collaboration between practitioners and healthcare providers and the people they serve is essential. This requires cultural humility driven by empathy. Empathy is a core prosocial value, a cognitive-emotional skill that helps us understand ourselves and others. This position paper aims to provide an overview of the vital roles of empathy, cooperation, and interdisciplinary partnerships. By consciously integrating this understanding in practice, leaders can better position themselves to address the diverse challenges faced by communities, promote inclusivity in policies and practices, and further more equitable solutions to the problem of global brain health.

Factors associated with healthy aging in Latin American populations

Latin American populations may present patterns of sociodemographic, ethnic and cultural diversity that can defy current universal models of healthy aging. The potential combination of risk factors that influence aging across populations in Latin American and Caribbean (LAC) countries is unknown. Compared to other regions where classical factors such as age and sex drive healthy aging, higher disparity-related factors and between-country variability could influence healthy aging in LAC countries. We investigated the combined impact of social determinants of health (SDH), lifestyle factors, cardiometabolic factors, mental health symptoms and demographics (age, sex) on healthy aging (cognition and functional ability) across LAC countries with different levels of socioeconomic development using cross-sectional and longitudinal machine learning models (n = 44,394 participants). Risk factors associated with social and health disparities, including SDH (β > 0.3), mental health (β > 0.6) and cardiometabolic risks (β > 0.22), significantly influenced healthy aging more than age and sex (with null or smaller effects: β < 0.2). These heterogeneous patterns were more pronounced in low-income to middle-income LAC countries compared to high-income LAC countries (cross-sectional comparisons), and in an upper-income to middle-income LAC country, Costa Rica, compared to China, a non-upper-income to middle-income LAC country (longitudinal comparisons). These inequity-associated and region-specific patterns inform national risk assessments of healthy aging in LAC countries and regionally tailored public health interventions.
