Official title
Assessing Skin Biomarkers for Preclinical Diagnosis of PD and Non-PD Parkinsonism
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine whether identification of misfolded proteins in the skin will help to determine what sort of parkinsonism someone has. We seek to demonstrate whether someone has a synucleinopathy such as Parkinson's disease (PD), multiple system atrophy (MSA), or dementia with Lewy bodies(DLB), as opposed to a tauopathy such as progressive supranuclear palsy (PSP) or corticobasal degeneration (CBD) or no parkinsonism at all (control).
