Brief Summary:
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).

Parkinson Disease Parkinsonism Dementia With Lewy Bodies Multiple System Atrophy Progressive Supranuclear Palsy Corticobasal Degeneration Procedure: punch skin biopsy

Detailed Description:
This is a clinical research study for patients with parkinsonism, including Parkinson's disease, progressive supranuclear palsy, corticobasal degeneration, multiple system atrophy, and dementia with Lewy bodies. Parkinsonism can be difficult to diagnose, especially in the early stages of the disease. Skin punch biopsy could be a useful and way to diagnose and measure the severity of these conditions. Given that there currently is no proven way to determine that someone has a synucleinopathy such as PD and not a tauopathy, this is a novel study that may lead to better ways to diagnose people with parkinsonism. The purpose of the study is to identify changes on a skin punch biopsy, in which small samples of skin are removed and sent to the laboratory for examination. We are seeking to measure the amount of misfolded alpha-synuclein in someone's skin. Participation will last between 1 and 2 years and will involve between 2 and 4 visits. Visits will include a physical examination, questionnaires, a memory test, blood draws, and a single visit for skin punch biopsies. We will also be looking to enroll volunteers to serve as "controls," who do not have any neurological illness.

Estimated Study Completion Date : May 31, 2024


Group/Cohort Intervention/treatment
Parkinsonism Group
Participants with Parkinson's disease (PD), dementia with Lewy bodies (DLB), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD)
Procedure: punch skin biopsy
An anesthetic medication is injected to numb the areas of skin and two samples of skin are obtained from punch biopsy.

Participants without parkinsonism
Procedure: punch skin biopsy
An anesthetic medication is injected to numb the areas of skin and two samples of skin are obtained from punch biopsy.




Primary Outcome Measures :
  1. Amount of alpha-synuclein in the skin [ Time Frame: Cross-sectional at baseline ]
    Alpha-synuclein will be measured by RT-QuIC and sPMCA

  2. Change in PSPRS measures of progressive supranuclear palsy (PSP) severity in people with PSP [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Questionnaire and examination. Lower scores are better.

  3. Change in UMSARS measures of multiple system atrophy (MSA) severity in people with MSA [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Questionnaire and examination. Lower scores are better.

  4. Change in Hoehn and Yahr (H&Y) and modified H&Y Scores [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Zero to 5 parkinsonism rating scale score. Lower score is better.

  5. Change in Schwab and England (S&E) Score [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    0% to 100% rating scale score. Higher score is better.


Secondary Outcome Measures :
  1. Change in Montreal Cognitive Assessment (MoCA) [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Zero to 30 cognitive rating scale score. Higher score is better.

  2. Change in Epworth Sleepiness Scale (ESS) [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Zero to 24 sleepiness rating scale score. Lower score is better.

  3. Change in Hamilton depression scale [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    17 item depression rating scale score. Lower score is better.

  4. Change in Hamilton anxiety scale [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    14 item depression rating scale score. Lower score is better.

  5. Change in REM Behavior Disorder Questionnaire [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    10 item depression rating scale score. Lower score is better.

  6. Change in blood pressure with orthostatic posture [ Time Frame: Baseline, 1 year, and optional 2 year assessment ]
    Blood pressure from lying down to sitting to standing. Smaller drop in blood pressure is better.

  7. Amount of alpha-synuclein in the blood [ Time Frame: Baseline, optional 1 year assessment, and optional 2 year assessment ]
    Alpha-synuclein will be measured in the blood sample

  8. Change in PDQ-39 [ Time Frame: Baseline, optional 1 year assessment, and optional 2 year assessment ]
    39 item health status questionnaire. Lower is better.


Biospecimen Retention:   Samples With DNA
Skin and blood samples are collected and used for analysis in the Case Western Reserve University Department of Pathology. Blood samples are obtained for NIH affiliated biobanks BioSEND/PDBP and RUCDR.
