Clinical advantage: This technology belongs to extracranial tissues α-Syn aggregate testing can replace brain biopsy procedures that are difficult to carry out clinically, thus breaking through the limitations of clinical experience in diagnosing a-synuclein lineage diseases and greatly improving the diagnostic and differential diagnostic level of this group of diseases.\n\nClinical needs: α-Synaptic nucleoprotein lineage diseases (Parkinson's disease, multisystem atrophy, and Lewy body dementia) have complex early symptoms, making diagnosis and differential diagnosis difficult. Early diagnosis is crucial for disease prognosis. Authoritative theories suggest that brain tissue biopsy is necessary for the diagnosis of this group of diseases, but it is difficult to generalize in clinical practice. Therefore, there is a 20% misdiagnosis and missed diagnosis rate in the clinical diagnosis of α-synaptic nuclear protein spectrum diseases. The α-Synuclein Ultrafine Fluorescence Detection Method for body fluids and skin in Parkinson's patients can truly reflect the degree of pathological aggregation in synapses, which is helpful for early diagnosis and evaluation of diseases."}, "eligibilityModule"=>{"sex"=>"ALL", "stdAges"=>["ADULT", "OLDER_ADULT"], "maximumAge"=>"80 years", "minimumAge"=>"18 years", "samplingMethod"=>"NON_PROBABILITY_SAMPLE", "studyPopulation"=>"1) patients with clinically defined PD; 2) patients with clinically probable PD; 3) MSA group; 4) PSP group; 5) healthy subjects of equal age and sex without any risk or prodromal factor for PD.", "healthyVolunteers"=>true, "eligibilityCriteria"=>"Inclusion Criteria:\n\n* Patients with clinically defined or probable PD：According to the 2015 MDS diagnostic criteria, patients diagnosed with \"clinically confirmed PD\" regardless of age, gender, and meeting Hoehn\\&Yahr staging ≤ 2.5 were included as case group one, which met \\[Parkinson's syndrome+at least two supportive criteria+no absolute exclusion criteria\\]\n* Patients with clinically probable PD：According to the 2015 MDS diagnostic criteria, patients diagnosed with \"clinically probable PD\", regardless of age or gender, and meeting Hoehn\\&Yahr staging ≤ 2.5 were included as case group two, i.e. patients who met \\[Parkinson's syndrome+no absolute exclusion criteria+1/2 supportive criteria+1/2 warning signs\\]\n* MSA group：Adult onset (\\>30 years old), sporadic and progressive development, and possessing the following characteristics: 1 Has one of the following two conditions: ① Parkinson's syndrome with levodopa adverse response (bradykinesia, accompanied by muscle rigidity, tremors, or postural instability), ② cerebellar dysfunction: gait ataxia, accompanied by cerebellar articulation disorders, limb ataxia, or cerebellar eye movement disorders; 2.
