Publication Advancements in dementia research, diagnostics, and care in Latin America: Highlights from the 2023 Alzheimer's Association International conference satellite symposium in Mexico City(2024) Sosa, Ana; Brucki; Sonia; Crivelli, Lucia; Lopera, Francisco; Acosta, Daisy; Acosta, Juliana; Aguilar, Diego; Aguilar.Sara; Allegri, Ricardo; Bertolucci, Paulo; Calandri, Ismael; Carrillo, Maria; Chrem , Patricio; Cornejo, Mario; Custodio, Nilton; Damian, Andrés; Cruz , Leonardo; Duran, Claudia; García, Adolfo; García, Carmen; Gonzales, Mitzi; Grinberg, Lea; Ibanez, Agustin; Illanes, Maryenela; Jack, Clifford; Leon, Jorge; Llibre, Jorge; Luna, José; Matallana, Diana; Miller, Bruce; Naci, Lorina; Parra, Mario; Pericak, Margaret; Piña, Stefanie; França, Elisa de Paula; Ringman, John; Sevlever, Gustavo; Slachevsky Chonchol, Andrea; Kimie, Claudia; Valcour, Victor; Villegas, AndresIntroduction: While Latin America (LatAm) is facing an increasing burden of dementia due to the rapid aging of the population, it remains underrepresented in dementia research, diagnostics, and care. Methods: In 2023, the Alzheimer's Association hosted its eighth satellite symposium in Mexico, highlighting emerging dementia research, priorities, and challenges within LatAm. Results: Significant initiatives in the region, including intracountry support, showcased their efforts in fostering national and international collaborations; genetic studies unveiled the unique genetic admixture in LatAm; researchers conducting emerging clinical trials discussed ongoing culturally specific interventions; and the urgent need to harmonize practices and studies, improve diagnosis and care, and use affordable biomarkers in the region was highlighted. Discussion: The myriad of topics discussed at the 2023 AAIC satellite symposium highlighted the growing research efforts in LatAm, providing valuable insights into dementia biology, genetics, epidemiology, treatment, and care.Publication Social exposome and brain health outcomes of dementia across Latin America(2025) Migeot, Joaquin; Pina, Stefanie; Hernandez, Hernan; Gonzalez, Raul; Legaz, Agustina; Fittipaldi, Sol; Resende, Elisa de Paula França; Duran, Claudia; Avila, Jose; Behrens, Maria Isabel; Bruno, Martin; Cardona, Juan; Custodio, Nilton; García, Adolfo; Godoy, Maria; Hu, Kun; Lanata, Serggio; Lawlor, Brian; Lopera, Francisco; Maito, Marcelo; Matallana, Diana; Miller, Bruce; Miranda, J Jaime; Okada, Maira; Reyes, Pablo; Santamaria, Hernando; Slachevsky Chonchol, Andrea; Sosa, Ana; Takada, Leonel; Torres, Jacqueline; Vanneste, Sven; Valcour, Victor; Wen, Olivia; Yokoyama, Jennifer; Possin, Katherine; Ibañez, AgustinA multidimensional social exposome (MSE)-the combined lifespan measures of education, food insecurity, financial status, access to healthcare, childhood experiences, and more-may shape dementia risk and brain health over the lifespan, particularly in underserved regions like Latin America. However, the MSE effects on brain health and dementia are unknown. We evaluated 2211 individuals (controls, Alzheimer's disease, and frontotemporal lobar degeneration) from a non-representative sample across six Latin American countries. Adverse exposomes associate with poorer cognition in healthy aging. In dementia, more complex exposomes correlate with lower cognitive and functional performance, higher neuropsychiatric symptoms, and brain structural and connectivity alterations in frontal-temporal-limbic and cerebellar regions. Food insecurity, financial resources, subjective socioeconomic status, and access to healthcare emerge as critical predictors. Cumulative exposome measures surpass isolated factors in predicting clinical-cognitive profiles. Multiple sensitivity analyses confirm our results. Findings highlight the need for personalized approaches integrating MSE across the lifespan, emphasizing prevention and interventions targeting social disparities.Publication The Latin American Brain Health Institute, a regional initiative to reduce the scale and impact of dementia(2022) Duran, Claudia; Sanhueza, Jorge; Grinberg, Lea; Slachevsky, Andrea; Valcour, Víctor; Robertson, Ian; Lawlor, Brian; Miller, Bruce; Ibáñez, AgustínLatin American and Caribbean countries face complex challenges to improve brain health and reduce the impact of dementia. Regional hubs devoted to research, capacity building, implementation science, and education are critically needed. The Latin American Brain Health Institute represent an important step to address many of these needs.
