Clinical Research Advances and Future Perspectives in Frontotemporal Dementia

Frontotemporal dementia (FTD) refers to a spectrum of neurodegenerative disorders primarily affecting the frontal and/or temporal lobes. Given the marked clinical, genetic, and pathological heterogeneity, achieving accurate antemortem diagnosis and pathological subtyping remains a significant challenge. Recent genetic studies have revealed differences in the genetic landscape of FTD across populations; meanwhile, progress in body fluid and peripheral tissue biomarkers, seed amplification assays, and neuroimaging technologies has provided powerful tools for pathology-based early diagnosis. The research focus in the field of FTD treatment has gradually shifted from symptomatic treatment to disease-modifying therapies and neuromodulation. This review focuses on the latest advances in clinical research of FTD, aiming to provide a reference for the formulation of precise diagnosis and treatment strategies for this disease.
