Of nine patients followed up for 6 to 16 years, two were diagnosed pathologically: pallidonigroluysian degeneration (PNLD) and diffuse Lewy body disease. Four others evolved clinically into progressive supranuclear palsy and corticobasal degeneration. PPFG is not a distinct disorder but a syndrome with diverse causes. Long-term follow-up (≥10 years) and postmortem are required for accurate diagnosis. PNLD may be the primary form of disease.展开更多
冻结步态(freezing of gait,FoG)是一种间歇性发作的步态异常症状,常见于帕金森病(Parkinson’s disease,PD)晚期,且被认为是PD的一个独立核心症状。本文中统一将从未出现过FoG症状的PD患者记为PD FoG-,将已有过FoG症状出现的PD患者记为...冻结步态(freezing of gait,FoG)是一种间歇性发作的步态异常症状,常见于帕金森病(Parkinson’s disease,PD)晚期,且被认为是PD的一个独立核心症状。本文中统一将从未出现过FoG症状的PD患者记为PD FoG-,将已有过FoG症状出现的PD患者记为PD FoG+。目前已有许多神经电生理学研究基于可量化的大脑电信号——主要是脑电信号(electroencephalogram,EEG)和局部场电位信号(local field potentials,LFPs),深入探索了PD FoG+神经通路中可能与FoG相关的病理生理变化。本文将分别对近年来以EEG和LFPs为主要分析对象的FoG病理机制相关研究进行综述。展开更多
