Multi-Center Study of Natural History in Atypical Parkinsonian Syndromes (MAPS-NH)

This goal of this observational study is to clarify the variations in the natural course of atypical parkinsonian syndromes (APS, including MSA, DLB, PSP, and CBD), such as the progression rate of motor and non-motor symptoms and characteristic imaging evolution patterns. Establish a comprehensive assessment framework for APS, and develop clinical and biological databases to identify biomarkers with early predictive value.
