Uncovering Clinical and Functional Neuroimaging Characteristics of Overt Stage Phenotypes Within the α-Synucleinopathy Spectrum

This study emphasizes how DLB with RBD and PD without RBD represent opposite ends of the neuronal α-synucleinopathy spectrum. The study highlights both overlapping and divergent clinical and neuroimaging features, with PD with RBD patients displaying an intermediate profile.
