Biomarkers for differentiation of Parkinson*s disease subtypes. - Biomarkers for Parkinson*s disease subtypes.

Short title used by the registry

Biomarkers for differentiation of Parkinson*s disease subtypes.

Original description

Primary outcome: The main study parameters of this study will include magnetic resonance imaging (MRI) parameters, and clinical measures. Clinical data include important demographic and disease-related characteristics as well as measures for disease severity, and the important motor (motor functioning and motor complications), and non-motor domains (cognition, depression, psychotic symptoms, sleep problems, and autonomic dysfunction). The combination of clinical scores will allocate PD patients in one of the four subtypes. MRI will be carried out on a 3T scanner and will include volumetric, diffusion, and functional MRI parameters. Secondary outcome: Not applicable.
