Reduced brain activity responding to unpredicted visual changes is a marker of psychosis in Parkinson’s disease and a potential therapeutic target. Researchers at the IoPPN used electroencephalography (EEG) to observe participant’s brain activity when presented with these visual cues. The aim is to determine whether visual mismatch negativity (vMMN) can be used to distinguish PD with visual hallucinations and PD without. The work is published in the journal Brain Communications.
