Background: Isolated rapid eye movement sleep behavior disorder (iRBD) is prodromal for α-synucleinopathies. Objective: The aim of this study was to determine whether pathological cardiac [123I]meta-iodobenzylguanidine scintigraphy ([123I]MIBG) is associated with progression of [18F]fluorodeoxyglucose-positron emission tomography–based Parkinson's disease (PD)-related brain pattern (PDRP) expression in iRBD. Methods: Seventeen subjects with iRBD underwent [18F]fluorodeoxyglucose-positron emission tomography brain imaging twice ~3.6 years apart. In addition, [123I]MIBG and [123I]N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane single-photon emission computed tomography ([123I]FP-CIT-SPECT) at baseline were performed. Olfactory, cognitive, and motor functions were tested annually. Results: Twelve of 17 subjects had pathological [123I]MIBG. At baseline, 6 of 12 of these expressed the PDRP (suprathreshold PDRP z score). At follow-up, 12 of 17 subjects had suprathreshold PDRP z scores, associated with pathological [123I]MIBG in 92% and with pathological [123I]FP-CIT-SPECT in 75%. Subjects with pathological [123I]MIBG had higher PDRP z score change per year (P = 0.027). Three subjects phenoconverted to PD; all had pathological [123I]MIBG and [123I]FP-CIT-SPECT, suprathreshold baseline PDRP z scores, and hyposmia. Conclusions: Pathological [123I]MIBG was associated with progressive and suprathreshold PDRP z scores at follow-up. Abnormal [123I]MIBG likely identifies iRBD as prodromal PD earlier than pathological [123I]FP-CIT-SPECT. © 2021 The Authors.
