Abstract Alzheimer’s disease and related dementia (ADRD) represents a growing public health burden, especially in low- and middle-income countries. Yet, most studies focus on Non-Hispanic white (NHW) populations from high-income countries. This study investigates plasma proteomic signatures associated with amyloid pathology in African populations. Nigerian older adults from the VALIANT study and participants from a Tanzanian study, with available biomarker quantification in plasma are employed.

Abstract Africa stands at a decisive moment in which urgent action is essential to safeguard its brain health and economic stability. While Africa’s population remains predominantly young, it is expanding and aging rapidly. This demographic shift is projected to drive a sharp rise in neurodegenerative diseases, including Alzheimer’s, with profound health and economic costs—but brain health research, policy, funding and care across the continent remain critically underdeveloped.

Abstract Clinical and genetic studies have implicated lipid dysfunction in Alzheimer Disease (AD) pathogenesis. While the etiologic impact of lipid intake on individuals is receiving attention, the role of food systems in shaping community-level incidence remains uncharacterized. Mean country-level lipid intakes were compared to Age-Standardized Alzheimer-and-other-Dementia Incidence Rates (ASAIR) in 183 countries across all inhabited continents.
