Inclusion criteria

Inclusion criteria: 1 Inclusion criteria: Clinical trial study participants must meet all of the following criteria: 1.1 Healthy volunteers: (1) between 45 and 75 years old; No gender limitation. (2) The cognitive function was found to be normal by the researchers through cognitive tests. The UPDRS III score is 0. (3) No neurological diseases, major chronic diseases, malignant tumors or acute infectious diseases have been confirmed by researchers. (4) No family history of neurological diseases related to movement disorders and cognitive disorders. (5) Understand and sign written informed consent prior to any assessment. (6) Female study participants must have medical records showing that they have been surgically sterilized (such as hysterectomy, bilateral ovariectomy, or tubal ligation) or have been menopausal for more than one year; If you are still able to conceive, you should use isolation contraception within 3 months after the start of the study. (7) Male study participants were required to use isolation contraception within 3 months of the start of the study. Male study participants were not allowed to donate sperm for 3 months after the start of the study. (8) Willing and able to cooperate with all projects of this study. 1.2 PD patients: (1) between 45 and 75 years old; No gender limitation. (2) Patients should meet the diagnostic criteria for PD (2015 PD Diagnostic Guidelines formulated by MDS of the International Movement Disorders Society) 4. The diagnosis was made independently by 2 specialists in the Department of Neurology of Huashan Hospital. Patients whose diagnosis is disputed shall be discussed and decided by the movement disorder special team of the Department of Neurology, Huashan Hospital. However, the necessary a-syn related pathological examination recommended by the diagnostic criteria should be carried out in the subsequent research process, and the necessary diagnosis confirmation or diagnosis change should be carried out. (3) Brain MRI supported PD diagnosis, and there was no evidence of other neurological diseases. (4) Drugs used to improve the clinical symptoms of neurodegenerative movement disorders must be maintained at a steady dose for more than 30 days before starting the study. (5) Study participants may be accompanied by caregivers if necessary. (6) Study participants or their legal representatives understand and sign written informed consent prior to any evaluation. (7) Female study participants must have medical records showing that they have been surgically sterilized (such as hysterectomy, bilateral ovariectomy, or tubal ligation) or have been menopausal for more than one year; If you are still able to conceive, you should use isolation contraception within 3 months after the start of the study. (8) Male study participants were required to use isolation contraception within 3 months of the start of the study. Male study participants were not allowed to donate sperm for 3 months after the start of the study. (9) Willing and able to cooperate with all projects of this study.1.3 MSA patients: (1) between 45 and 75 years old; No gender limitation. (2) MSA diagnostic criteria for patients (the third edition of MSA diagnostic criteria formulated by MDS of the International Movement Disorders Society) 5. The diagnosis was made independently by 2 specialists in the Department of Neurology of Huashan Hospital. Patients whose diagnosis is disputed shall be discussed and decided by the movement disorder special team of the Dep

Exclusion criteria

Exclusion criteria: 2 Exclusion criteria: Study participants who meet any of the following criteria will be excluded from the study: 2.1 Healthy controls: (1) Patients with neurodegenerative diseases, or suffering from serious other neurological diseases, or gastrointestinal, cardiovascular, liver, kidney, blood system, tumor, endocrine, respiratory, immune deficiency and other serious diseases.
