Amyotrophic lateral sclerosis in Mainland China: clinical translational challenges and opportunities.

Abstract

Purpose of review: Amyotrophic lateral sclerosis (ALS) imposes a growing medical and socioeconomic burden in China. This review synthesizes recent advances in understanding ALS epidemiology, biomarker discovery, therapeutic innovations, and policy frameworks in China. It highlights the urgency of addressing challenges, including fragmented healthcare resources, translational medicine gaps, and regional inequities, while emphasizing China's unique contributions to global ALS research.

Recent findings: Chinese ALS cohorts exhibit distinct epidemiological profiles, including a younger mean age of onset and prolonged median survival. Policy initiatives, such as ALS inclusion in rare disease registries and insurance reforms, aim to reduce financial burdens of patients. Multimodal biomarker exploration has advanced integrated diagnostic models combining neurofilament light chain (NfL) and clinical data platforms. Neuroimaging and electrophysiological studies reveal glymphatic dysfunction, white matter degeneration, and neuromuscular junction abnormalities, with novel links to hepatic metabolism. Genomic analyses identify population-specific variants. Therapeutic innovations in China include not only biopharmaceuticals, but also integrative traditional Chinese medicine (TCM) approaches.

Summary: China's ALS landscape is transitioning towards precision medicine through biomarker-guided diagnostics and multidisciplinary care models. Key priorities include establishing a national ALS registry, standardizing biomarker validation, and expanding clinical trials to bridge translational medicine gaps.
