AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults aged 40 to 75 with multiple system atrophy or Parkinson disease, and for healthy or disease-free controls.
- Age
- 40 to 75 years
- Sex
- All sexes can join.
- Disease stage
- Clinically established or clinically probable multiple system atrophy (2022 Movement Disorder Society criteria), or clinically established or clinically probable Parkinson disease. Controls without hereditary or neurodegenerative diseases can also join.
Main reasons for not taking part
- Parkinsonism that cannot be classified as Parkinson disease or multiple system atrophy
- Other atypical parkinsonian syndromes such as progressive supranuclear palsy, dementia with Lewy bodies, or corticobasal syndrome
- Secondary parkinsonism, for example from a brain lesion, normal pressure hydrocephalus, or drugs
- Other diseases that may strongly affect autonomic function, such as diabetic peripheral neuropathy or amyloidosis
- Psychiatric or behavioral problems that prevent reliable data collection or scale-based assessment

- Original description
Multiple system atrophy is a rare, rapidly progressive neurodegenerative disease characterized by variable combinations of parkinsonism, cerebellar ataxia, and autonomic dysfunction. Existing natural history studies from North America, Europe, and Japan suggest that clinical phenotypes and disease progression may differ across populations. However, comprehensive multicenter prospective data from Chinese patients with multiple system atrophy remain limited.Read full original descriptionShow less
Clinical Features and Natural History of Multiple System Atrophy: A Prospective Multicenter Registry Study in China
Multiple system atrophy is a rare, rapidly progressive neurodegenerative disease characterized by variable combinations of parkinsonism, cerebellar ataxia, and autonomic dysfunction. Existing natural history studies from North America, Europe, and Japan suggest that clinical phenotypes and disease progression may differ across populations. However, comprehensive multicenter prospective data from Chinese patients with multiple system atrophy remain limited.
This prospective multicenter registry study aims to describe the clinical characteristics, longitudinal progression, and outcomes of Chinese patients with multiple system atrophy, to identify factors associated with disease progression and prognosis, and to establish a longitudinal cohort for future biomarker validation and clinical trial design.
Inclusion: Patients with clinically established or clinically probable multiple system atrophy according to the 2022 Movement Disorder Society diagnostic criteria; or; Patients with clinically established or clinically probable Parkinson disease according to the Movement Disorder Society diagnostic criteria; or; Healthy controls or controls without hereditary or neurodegenerative diseases who voluntarily agree to participate; Age between 40 and 75 years; Ability to provide informed consent or availability of a legally authorized representative when applicable.
Exclusion: Secondary parkinsonism due to intracranial space-occupying lesions, normal pressure hydrocephalus, drug-induced parkinsonism, or other identifiable causes; Parkinsonism that cannot be classified as Parkinson disease or multiple system atrophy at the time of evaluation; Clinical suspicion or diagnosis of other atypical parkinsonian syndromes, including progressive supranuclear palsy, dementia with Lewy bodies, or corticobasal syndrome; Comorbid diseases that may substantially affect autonomic function, such as diabetic peripheral neuropathy or amyloidosis; Refusal to participate in the study or refusal to undergo routine clinical evaluations for parkinsonian syndromes; Psychiatric or behavioral abnormalities that preclude reliable clinical data collection or scale-based assessment.
