Baseline neurological exposome characteristics in a nationwide community-based screening cohort for movement disorders in marginalized and integrated Roma populations

Background: Roma, the largest ethnic minority in Europe,, are almost absent from movement-disorder research despite living in environments with biomass combustion, poor sanitation, and unprotected water, creating a high-risk neurological exposome. Objective: To describe baseline exposome profiles in a nationwide Roma screening cohort and compare exposures between marginalized and integrated communities, and between screen-positive and screen-negative participants. Methods: A nationwide community-based program combined door-to-door recruitment of marginalized Roma with recruitment of integrated Roma through neurological services. Participants completed standardized exposome questionnaires and
