“…Advanced neuroimaging techniques are a promising method to identify structural and functional features that could assess the risk of conversion toward alpha-synucleinopathies. Very recently, neuroimaging data, mostly from structural MRI, combining different techniques, have been reviewed (Campabadal et al, 2019 ; Ghaderi et al, 2023 ; Valli et al, 2022 ), highlighting the presence of cortical and subcortical abnormalities, involving basal ganglia and fronto-temporal cortices in iRBD patients (Unger et al, 2010 , Rahayel et al, 2015 , 2018a , b , Chen et al, 2022 , Hanyu et al, 2012 , Matzaras et al, 2022 , Scherfler et al, 2011 ) and in PD with RBD (Boucetta et al, 2016 ; Jia et al, 2022 ; Lim et al, 2016 ; Rahayel et al, 2019 ; Salsone et al, 2014 ). Although PD with RBD patients had a more prominent involvement of the thalamus, putamen, insula, precuneus, para-hippocampal, and postcentral gyrus, iRBD had the internal capsule, caudate, thalamus, and fornix more involved (Campabadal et al, 2019 ; Valli et al, 2022 ).…”
