Exploration of the Association Between White Matter Lesion Burden and Dalfampridine Response in Insidious-Onset Vascular Parkinsonism (DAL-VaP)
An Exploratory Cohort Study to Evaluate Whether White Matter Lesion Burden Correlates With Dalfampridine Response in Insidious-Onset Vascular Parkinsonism and Parkinson-Plus Syndromes
調査の概要

詳細な説明
Insidious-onset vascular parkinsonism (VaP) is characterized by typical clinical manifestations including gait impairment, postural instability, poor levodopa responsiveness, and diffuse cerebral white matter lesions (WMLs). Dalfampridine is an agent indicated to manage gait dysfunction among patients diagnosed with multiple sclerosis. This study will collect standardized gait and functional scale assessments in participants with insidious-onset VaP and participants with Parkinson-plus syndromes (PPS).
Single-center observational cohort study performed at Tangdu Hospital, Fourth Military Medical University, Xi'an, China. Parkinsonism and poor levodopa response will be divided into two diagnostic subgroups (VaP, PPS). Each subgroup will receive one of two treatment regimens: dalfampridine 10 mg twice daily for 4 weeks plus conventional therapy, or conventional therapy alone.
Change in Timed Up and Go (TUG) test time,10-meter walking speed, Tinetti scale score, ADL scale score, FES-I score, FOG-Q score, and SF-36 summary scores recorded at baseline and Week 4 among participants with VaP.
Baseline white matter lesion volume will be documented as a baseline clinical characteristic of all enrolled participants.
