Blinded comparison of different alpha-synuclein seeding assays as cutaneous biomarkers of Lewy body dementias. Beach-NIH/R01 (NS118669-01).


The purpose of this research is to determine the ability of skin biopsy analysis to predict a diagnosis of Lewy body dementia, and to determine whether the results of the skin biopsy analyses change over time. Lewy body dementias include Parkinson’s disease with dementia as well as dementia with Lewy bodies.
