• 1 other identifier: 642
• Study Type: observational
• Target: 200
• Locations: 1 country

Brief Summary

This is a prospective observational study to identify biomarkers in parkinson syndromes. Patients with parkinsonian syndromes at the early stages of disease will be recruited and will be followed up until their established clinical diagnosis or for at least 5 years. In this population, imaging and wet biomarkers as well as clinical data will b systematically collected.

Conditions

Parkinson Disease; Progressive Supranuclear Palsy; Multiple System Atrophy; Atypical Parkinsonism; Parkinsonism

Keywords
