Abstract
Introduction: Although Hispanic/Latine populations experience higher dementia rates, they remain underrepresented in frontotemporal dementia (FTD) research. This study examines clinical manifestations of FTD within a South Texas Hispanic/Latine cohort compared to national data.
Methods: Participants diagnosed with FTD were included from (1) our FTD clinic, the South Texas Alzheimer's Disease Research Center, and local Advancing Research and Treatment in Frontotemporal Lobar Degeneration-Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects Longitudinal Frontotemporal Lobar Degeneration cohort (Hispanic: n = 17; White non-Hispanic: n = 22), and (2) the National Alzheimer's Coordinating Center dataset (Hispanic: n = 24; White non-Hispanic: n = 407; National Institute on Aging/National Institutes of Health Grant U24 AG072122). Clinical, neuroimaging, and neuropsychological data were harmonized for cross-cohort comparisons.
Results: Hispanic participants presented with more movement-related symptoms and advanced cognitive impairment at diagnosis than non-Hispanic Whites. Diagnostic delays averaged 4 years from symptom onset. Educational disparities significantly contributed to health-care access differences.
Discussion: Findings underscore diagnostic severity and systemic barriers faced by Hispanic populations with FTD, emphasizing the need for culturally sensitive diagnostic tools and interventions for equitable dementia care.
期刊介绍：
Alzheimer''s & Dementia: Diagnosis, Assessment & Disease Monitoring (DADM) is an open access, peer-reviewed, journal from the Alzheimer''s Association® that will publish new research that reports the discovery, development and validation of instruments, technologies, algorithms, and innovative processes. Papers will cover a range of topics interested in the early and accurate detection of individuals with memory complaints and/or among asymptomatic individuals at elevated risk for various forms of memory disorders. The expectation for published papers will be to translate fundamental knowledge about the neurobiology of the disease into practical reports that describe both the conceptual and methodological aspects of the submitted scientific inquiry. Published topics will explore the development of biomarkers, surrogate markers, and conceptual/methodological challenges. Publication priority will be given to papers that 1) describe putative surrogate markers that accurately track disease progression, 2) biomarkers that fulfill international regulatory requirements, 3) reports from large, well-characterized population-based cohorts that comprise the heterogeneity and diversity of asymptomatic individuals and 4) algorithmic development that considers multi-marker arrays (e.g., integrated-omics, genetics, biofluids, imaging, etc.) and advanced computational analytics and technologies.
