Introduction: Functional movement disorders (FMDs) are abnormal involuntary movements that cannot be explained by structural neurological disease and fall under the spectrum of functional neurological disorders. Although much is known about FMDs in general, there is a paucity of data on their presentation, diagnosis, and management in older adults, particularly in Latin America. Objective: To review the available literature on FMDs in older adults (aged ≥ 65) in Latin America, focusing on epidemiology, clinical features, diagnostic challenges, treatment, and prognosis, and to identify research gaps and priorities. Methods: Systematic searches were conducted in PubMed, Embase, LILACS, SciELO, Scopus, Science Direct, and Google Scholar for studies reporting FMDs in older adults in Latin America during the last 10 years. Additionally, the study was registered in PROSPERO (CRD420251250181). Data extracted included country, sample size, mean/median age, FMD phenotype, diagnostic approach, treatment, and outcomes. However, narrative synthesis was used due to heterogeneity and paucity of data. Documents in English and Spanish were analyzed. Results: The search strategy and approach revealed extremely limited region-specific data. No eligible cohort or epidemiological studies focusing on older adults with FMDs in Latin America were identified. Existing reports are either descriptive or focus on younger adults; age-specific prevalence, phenotype distribution, and outcomes remain unknown. Conclusions: There is a major evidence gap concerning FMDs in older adults in Latin America, which poses clinical risks including misdiagnosis, delayed rehabilitation, and missed age-appropriate management. A region-tailored research agenda is proposed, including epidemiological studies, age-stratified cohorts, diagnostic and therapeutic adaptations, and capacity-building for multidisciplinary care. In light of the limited availability of region-specific data, this review integrates global evidence on FMDs in older adults and evaluates its relevance and implications for the Latin American setting.
