Summary

Currently, there is no clear diagnostic test that can be used to confirm the diagnosis of Parkinson's disease, or a biomarker that can track its progression. Patients with Parkinson's have many abnormalities of the autonomic nervous system, which may be related to Parkinson's changes outside of the brain. A new device called the SudoScan, which measures autonomic sweating changes, may be a simple way to test for autonomic changes in Parkinson's. The investigator plan to see whether SudoScan can identify Parkinson's disease and whether SudoScan abnormalities might be present even in early (prodromal) Parkinson's stages. The investigator will assess SudoScan in a group of Parkinson's patients, normal healthy controls, patients with non-Parkinson's neurodegeneration, and patients with REM sleep behavior disorder (an early/prodromal Parkinson's state). Abnormalities will be correlated with standard autonomic tests and with skin biopsy findings Parkinson's degeneration in the peripheral autonomic fibers. If the investigator can find a reliable way to diagnose and follow Parkinson's disease, he will be able to correctly identify Parkinson's (even in its earliest stages). This will improve the chance to find protective treatments against Parkinson's, by preventing false diagnosis and by providing a new marker to track disease progression. If successful, the investigator will aim to validate the findings on a large sample of Parkinson's and also to track changes over time in the original cohorts

Conditions

• Parkinson's Disease

Interventions

Type	Name	Description
DEVICE	Sudoscan and clinical assessment	The primary variable will be electrochemical skin conductance (ESC), as assessed by the SudoScan (Impeto Medical, France). The clinical assessment will include a neurological evaluation (including MDS-UPDRS), evaluation of autonomic symptoms and signs, EKG, evaluation of possible neuropathy and evaluation of non-motor variables.
GENETIC	Skin biopsy	Evaluation of the denervation and synuclein deposition of skin biopsy
