Abnormal event-related delta, theta, and alpha coherence response using visual oddball paradigm in Parkinson’s disease associated with cognitive impairment

Parkinson’s disease (PD) is a common neurodegenerative disease characterized by number of motor and non-motor dysfunctions. EEG pattern is a predictive of cognitive function in PD. In the present study, we investigated intra-hemispheric event related coherence with different cognitive dysfunctions in PD during visual oddball paradigm.
