Distinguishing Between Alzheimer's Disease, Lewy Body Dementia, and Parkinson's Disease
Douglas Scharre
Summary
The study is designed to characterize the clinical, neuropsychological, polysomnographic, and neuroimaging findings among subjects with Alzheimer's disease, Lewy Body dementia, and Parkinsons' Disease.
Description
The study will use structural and functional MRIs, daTscans, fluorodeoxyglucose (FDG) PET scans, Amyvid PET scans, polysomnographs, neuropsychological testing, cerebrospinal fluid in willing participants to distinguish between a diagnosis of Alzheimer's disease, Lewy Body dementia, and Parkinson's Disease. All subjects will have a clinical evaluation, physical examination including vital signs and orthostatic blood pressures and pulses, neurological examination including UPDRS evaluation, genetic blood sample collection, neuropsychological testing, polysomnogram, and neuroimaging. The study pa…
