In a recent Viewpoint article (JAMA Neurol. 2024;81:789‒90), Okubadejo et al. raised concerns regarding two recent proposals for biological definitions and staging systems for synucleinopathies (the Neuronal Synuclein Disease Integrated Staging System and SynNeurGe system). While acknowledging these concerns, we provide an alternative perspective—that such frameworks represent important steps forw…
