Parkinson Disease
Conditions
Brief summary
The objective of this study is the longitudinal prospective clinical evaluation in patients with motor predominant PD; it will assess the individual disease progression (change) of the clinical and imaging parameters measured at 6-month interval over a minimum of 12 months.
Detailed description
The absence of clear PD subtypes defining a common path and rate of disease progression, combined with the absence of validated biomarkers indicative of disease progression and a strong placebo effect, constitute a challenge for clinical trials assessing new potential disease-modifying therapies in PD. The present cohort would constitute a well-defined population of patients, with individual progression assessment, suitable to evaluate new disease-modifying therapies in a subsequent Phase1/2 clinical trial.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in Movement Disorders Society Unified Parkinson's Disease Rating Scale Part 3 (MDS-UPDRS Part III) off medications | baseline, 6, 12, 18, 24 and 30 months after baseline ] | An examiner will measure MDS-UPDRS part 3 motor scores off medications. MDS-UPDRS Part III is a motor examination consisting of 18 summed items where the investigator rates each motor symptom based on a scale of 0 - 4, higher values indicating worse function. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline of brain MRI | 12 and 24 months | neuromelanin sequence |
