Reduced volume of neuromodulatory brainstem nuclei is associated with early hallucination-related vulnerability in Parkinson’s disease
Abstract Early hallucination-related phenomena, including minor visual hallucinations (mVHs), are clinically relevant features of Parkinson’s disease (PD), but their neuroanatomical substrates remain unclear. Brainstem nuclei supporting sensory gating, together with cholinergic and noradrenergic dysregulation, are prop...
