Electrophysiological Signature of Mild Cognitive Impairment and Its Relationship with Parkinson's Disease: a High-density EEG Investigation
The study aims to investigate neural correlate of Mild Cognitive Impairment (MCI) in Parkinson's disease (PD) and to identify a link between functional impairment (in both cognitive and motor domains) and electrophysiological cortical sing of MCI in PD. A sample of 42 subjects will be divide into three subgroup: healthy control, PD with MCI (PD-MCI) and PD without MCI (PD-ctrl). Those subjects will undergo a specific neuropsychological evaluation and, to measure the electro-cortical activity, high-density electroencephalography (hdEEG) will be record during both resting state and cognitive tasks. Furthermore, hdEEG data will be combine with structural magnetic resonance to obtain information about network connectivity.
