Study Purpose

The purpose of this study is to identify changes on a skin punch biopsy or olfactory mucosa (tissue in the back of the nose) sampling, in which small pieces of skin are removed or a swab or brush is placed in the back of the nose, and then tissue is sent to the laboratory for examination.

A second arm of the study is for patients with and without Parkinson’s Disease dementia and dementia with lewy bodies who are already planning to have colonoscopy or sigmoidoscopy. These patients may volunteer to have a biopsy of their large intestine done for study purposes.

Who Can Participate

Participants between 40-89 years of age with Parksinson’s disease (PD), Alzheimer’s Disease, dementia with Lewy bodies (DLB), progressive palsy (PSP) and corticobasal degeneration or no neurological condition (controls) may be eligible for this study.
