Brief summary
The goal of this observational cohort studyis to establish a high-quality clinical cohort of Parkinson's disease (PD) and multiple system atrophy (MSA) patients in Shanghai, in order to improve early diagnosis, precise subtyping, disease monitoring, and to provide a resource for translational research and novel therapy development. The main questions it aims to answer are: * Can multimodal data (clinical, imaging, electrophysiology, biospecimens, and genetics) help identify early biomarkers for PD and MSA? * Can precise subtyping and long-term monitoring predict disease progression and therapeutic response? Researchers will compare 600 PD patients and 100 MSA patients to evaluate differences in clinical features, biomarkers, imaging, and prognosis. Participants will: * Provide informed consent and complete baseline demographic and medical history collection. * Undergo standardized clinical evaluations, including motor and non-motor symptom scales, cognitive and quality-of-life assessments. * Provide biological samples (blood, saliva, optional CSF). * Receive brain imaging (MRI, optional PET/SPECT) and electrophysiological recordings (EEG, fNIRS). * Participate in longitudinal follow-up visits every 6 months for repeat assessments. This study will create a sustainable, multicenter, and sharable cohort platform to support early identification, personalized intervention, and therapeutic development for neurodegenerative diseases

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in motor symptom severity assessed by MDS-UPDRS Part III | From baseline through 6-month and 12-month follow-up assessments | Motor symptom severity will be assessed using the Movement Disorder Society-Unified Parkinson's Disease Rating Scale Part III (MDS-UPDRS Part III; range 0-132, higher scores indicate worse motor impairment). The primary outcome is the change from baseline score. |
| Change from baseline in Hoehn & Yahr stage | From baseline through 6-month and 12-month follow-up assessments | Disease severity will be assessed using the Hoehn \& Yahr staging scale, which classifies Parkinson's disease severity on a scale from Stage 1 to Stage 5, with higher stages indicating more advanced disease. The secondary outcome is the change in Hoehn \& Yahr stage from baseline. |
| Change from baseline in Brief Pain Inventory (BPI) pain severity score | From baseline through 6-month and 12-month follow-up assessments | Pain severity will be assessed using the Brief Pain Inventory (BPI) pain severity subscale, with scores ranging from 0 to 10. Higher scores indicate more severe pain. The secondary outcome is the change from baseline in BPI pain severity score. |
| Change from baseline in REM Sleep Behavior Disorder Questionnaire-Hong Kong (RBDQ-HK) score | From baseline through 6-month and 12-month follow-up assessments | REM sleep behavior disorder symptoms will be assessed using the REM Sleep Behavior Disorder Questionnaire-Hong Kong (RBDQ-HK), with total scores ranging from 0 to 100. Higher scores indicate more severe RBD symptoms. The secondary outcome is the change from baseline in RBDQ-HK score. |
| Change from baseline in International Restless Legs Syndrome Study Group Rating Scale (IRLSS) score | From baseline through 6-month and 12-month follow-up assessments | Restless legs syndrome symptom severity will be assessed using the International Restless Legs Syndrome Study Group Rating Scale (IRLSS), with scores ranging from 0 to 40. Higher scores indicate more severe symptoms. The secondary outcome is the change from baseline in IRLSS score. |
| Change from baseline in University of Pennsylvania Smell Identification Test (UPSIT) score | From baseline through 6-month and 12-month follow-up assessments | Olfactory function will be assessed using the University of Pennsylvania Smell Identification Test (UPSIT), with scores ranging from 0 to 40. Lower scores indicate worse olfactory function. The secondary outcome is the change from baseline in UPSIT score. |
| Change from baseline in Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT) score | From baseline through 6-month and 12-month follow-up assessments | Autonomic dysfunction will be assessed using the Scales for Outcomes in Parkinson's Disease-Autonomic (SCOPA-AUT), with total scores ranging from 0 to 69. Higher scores indicate more severe autonomic dysfunction. The secondary outcome is the change from baseline in SCOPA-AUT score. |
| Change from baseline in Epworth Sleepiness Scale (ESS) score | From baseline through 6-month and 12-month follow-up assessments | Daytime sleepiness will be assessed using the Epworth Sleepiness Scale (ESS), with scores ranging from 0 to 24. Higher scores indicate greater daytime sleepiness. The secondary outcome is the change from baseline in ESS score. |
| Change from baseline in Pittsburgh Sleep Quality Index (PSQI) score | From baseline through 6-month and 12-month follow-up assessments | Sleep quality will be assessed using the Pittsburgh Sleep Quality Index (PSQI), with total scores ranging from 0 to 21. Higher scores indicate poorer sleep quality. The secondary outcome is the change from baseline in PSQI score. |
| Change from baseline in Hamilton Anxiety Rating Scale (HAMA) score | From baseline through 6-month and 12-month follow-up assessments | Anxiety symptoms will be assessed using the Hamilton Anxiety Rating Scale (HAMA), with total scores ranging from 0 to 56. Higher scores indicate more severe anxiety. The secondary outcome is the change from baseline in HAMA score. |
| Change from baseline in Hamilton Depression Rating Scale-17 (HAMD-17) score | From baseline through 6-month and 12-month follow-up assessments | Depressive symptoms will be assessed using the 17-item Hamilton Depression Rating Scale (HAMD-17), with total scores ranging from 0 to 52. Higher scores indicate more severe depressive symptoms. The secondary outcome is the change from baseline in HAMD-17 score. |
