Diagnostic Value of 123-I-MIBG Cardiac Scintigraphy for the Prediction of Conversion from Idiopathic REM Sleep Behavior Disorder to Dementia with Lewy Bodies, and the Differential Diagnosis of Neurodegenerative Diseases

The purpose of this study was to investigate the diagnostic availability of cMIBG in differentiating Parkinson's Disease (PD) and Dementia with Lewy Bodies (DLB) from related Neurodegenerative Diseases (NDDs) and to clarify the utility of cMIBG as a predicative biomarker for the conversion from Idiopathic REM Sleep Abnormal Behavior Disorder (iRBD) to α-synucleinopathies.
