Resting-state EEG measures cognitive impairment in Parkinson’s disease
Abstract Cognitive dysfunction is common in Parkinson’s disease (PD).We developed and evaluated an EEG-based biomarker to index cognitive functions in PD from a few minutes of resting-state EEG.We hypothesized that synchronous changes in EEG across the power spectrum can measure cognition.We optimized a data-driven algorithm to efficiently captur
