Abstract

Parkinson's disease (PD) is a neurodegenerative disorder characterized by α-synuclein aggregation in neurons. Recent advances suggest α-synuclein aggregates could serve as a biomarker for PD and related synucleinopathies. This study used surface-based fluorescence intensity distribution analysis (sFIDA) to measure α-synuclein aggregates in urine. Patients with PD and isolated rapid eye movement sleep behavior disorder, a precursor to PD, had elevated concentrations compared with healthy controls. Sensitivity and specificity were 83% and 65% for PD versus controls and 89% and 62% for isolated rapid eye movement sleep behavior disorder versus controls. The findings highlight sFIDA's potential for diagnosing synucleinopathies. ANN NEUROL 2025.

孤立性快速眼动睡眠行为障碍和帕金森病患者尿液中α-突触核蛋白聚集水平升高
帕金森病(PD)是一种以神经元α-突触核蛋白聚集为特征的神经退行性疾病。最近的研究表明α-突触核蛋白聚集体可以作为PD和相关突触核蛋白病的生物标志物。本研究采用基于表面的荧光强度分布分析法(sFIDA)测定尿中α-突触核蛋白聚集物。与健康对照组相比,患有PD和孤立的快速眼动睡眠行为障碍(PD的前兆)的患者浓度升高。PD对对照组的敏感性和特异性分别为83%和65%,孤立性快速眼动睡眠行为障碍对对照组的敏感性和特异性分别为89%和62%。这些发现强调了sFIDA在诊断突触核蛋白病方面的潜力。Ann neurol 2025。

期刊介绍: Annals of Neurology publishes original articles with potential for high impact in understanding the pathogenesis, clinical and laboratory features, diagnosis, treatment, outcomes and science underlying diseases of the human nervous system. Articles should ideally be of broad interest to the academic neurological community rather than solely to subspecialists in a particular field. Studies involving experimental model system, including those in cell and organ cultures and animals, of direct translational relevance to the understanding of neurological disease are also encouraged.
