MIBG in Aging and Neurologic Disorders
Myocardial 123I-MIBG Scintigraphy in Aging and Neurodegenerative Disease
The purpose of the study is to investigate the use of a special radioactive drug called 123I-MIBG and myocardial MIBG scintigraphy. This scan may be able to help determine who may have a certain kind of neurologic disorder called Lewy Body Disease.
The overall purpose of this study is to correlate myocardial MIBG scintigraphy findings with clinical diagnosis. Myocardial MIBG scintigraphy imaging will be combined with other clinical, neuropsychological and neuroimaging findings to improve the prediction for underlying Lewy Body Disease.

Detailed Description
Lewy body disease (LBD) is one of the most common neurodegenerative diseases and second only to Alzheimer's disease in terms of prevalence, disability, and societal/financial burden. The clinical variability of LBD is striking, as it can manifest as Parkinson's disease (PD), PD with dementia (PDD), dementia with Lewy bodies (DLB), mild cognitive impairment (MCI), REM sleep behavior disorder (RBD), among other disorders. Considerable evidence now suggests that accumulation of the pathological protein and neuronal loss evolve over decades with RBD and/or MCI beginning years before developing overt DLB or PD.
This project investigates the utility of myocardial 123I-MIBG scintigraphy using a radioactive agent AdreView™ in participants with normal neurologic functioning, REM sleep without atonia, RBD, parkinsonism, cognitive impairment, or some combination of these. This scan may be able to help determine who may have underlying LBD.
Myocardial 123I-MIBG scintigraphy is considered as one of the most important imaging tests in the international diagnostic criteria of DLB, and it is widely used in European countries and Japan. Despite its globally recognized scientific importance, the use of AdreView™ and myocardial 123I-MIBG scintigraphy in DLB and associated disorders is not approved in the US. Currently, the FDA-approved indication of AdreView™ is limited to assessing specific cardiac function and detecting pheochromocytoma or neuroblastoma.
The overall purpose of this study is to correlate myocardial MIBG scintigraphy findings with clinical diagnosis. Myocardial MIBG scintigraphy imaging will be combined with other clinical, neuropsychological and neuroimaging findings to improve the detection of LBD. This study will help investigators learn the utility of myocardial 123I-MIBG scintigraphy in identifying LBD in the early course of the disease, and to prepare for clinical trials targeting LBD pathophysiology.
