We are currently enrolling in 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 in the early stages of the disease. Skin biopsy could be a useful way to diagnose and measure the severity of these conditions. The purpose of the study is to identify changes on a skin punch biopsy, in which small pieces of skin are removed and sent to the laboratory for examination. Your participation will last between 1 and 2 years and will involve between 2 and 4 visits. Visits will include a physical exam, questionnaires, a memory test, a punch skin biopsy, and blood draw. We will also be looking to enroll volunteers to serve as “controls,” who do not have any neurological illness.

• You are 18-89 years old
• You have a diagnosis of any of the following: Parkinson’s Disease, multiple system atrophy, dementia with Lewy bodies, progressive supranuclear palsy, corticobasal degeneration, or no neurological condition (controls)
• You are not taking warfarin or other “anticoagulation” blood thinners
