Brief Summary
The main objective of the study is to design and validate the blood based PDx gene expression and miRNA assay for the early diagnosis of Parkinson's disease patients. Differential diagnosis includes patients with Multiple System Atrophy, Progressive Supranuclear Palsy, Corticobasal Degeneration, Lewy Body Dementia, Essential Tremor and Normal Controls.

Outcome Measures
Primary Outcomes (1)
The Diagnostic Accuracy of PDx mRNA Assay in Diagnosing Idiopathic Parkinson's Disease
Investigate the diagnostic accuracy of the PDx gene expression assay, comprised of 5-6 expressed genes (mRNA - RQ-PCR), to differentiate patients with Idiopathic Parkinson's disease from the Differential Diagnosis Group. Diagnostic Accuracy includes sensitivity, specificity, likelihood ratios and the area under the receiver operating characteristic (ROC) curve. Diagnostic Accuracy will be calculated by comparing the PDx assay results to the Gold Standard Diagnosis, which will be the Clinical diagnosis of the Patient one year after the first and only visit (day of blood collection). The physician investigator will be contacted if there was any change in the baseline diagnosis one year after blood collection according to routine clinical findings.
One year from enrollment
Secondary Outcomes (3)
Diagnostic Accuracy of each one of the PDx assay's expressed genes for Differentiating Idiopathic Parkinson's Disease Patients from Atypical Parkinsonism Patients.
One year from enrollment
Diagnostic Accuracy of each one of the PDx assay's expressed genes for Differentiating Idiopathic Parkinson's Disease Patients from Essential Tremor Patients.
One year from enrollment
Diagnostic Accuracy of each one of the PDx assay's expressed genes for Differentiating Idiopathic Parkinson's Disease Patients from Healthy Controls.
One year from enrollment
