Introduction The reduction of background activity and the increase of low-frequency powers
on electroencephalogram (EEG) correlate with cognitive impairment and have been …

Background: Slowing of the electroencephalogram (EEG) is frequent in Parkinson's (PD)
and Alzheimer's disease (AD) and correlates with cognitive decline. As overlap pathology …

Cognitive dysfunction can emerge during the clinical course of Parkinson's disease (PD)
even beginning in early stages, which requires extended neuropsychological tests for …

Objectives To identify quantitative EEG frequency and connectivity features (Phase Lag
Index) characteristic of mild cognitive impairment (MCI) in Parkinson's disease (PD) patients …

Objective We investigated whether a combination of qEEG variables, in particular signal
power in the alpha1 (8–10 Hz) and theta (4–8 Hz) bands, could represent a robust marker …

Objective The study objective is to evaluate the use of qEEG data for the cross‐sectional
differentiation of mild cognitive impairment (MCI) from mild Alzheimer's disease (AD) and in …

Background and purpose It is believed that progressive Lewy‐type synucleinopathy (LTS) is
primarily responsible for the worsening of motor and non‐motor Parkinson's disease (PD) …

Background: Quantitative electroencephalography (qEEG) has been suggested as a
biomarker for cognitive decline in Parkinson's disease (PD). Objective: Determine if applying …

Objective: We investigated quantitative electroencephalography (qEEG) and clinical
parameters as potential risk factors of severe cognitive decline in Parkinson's disease …

Objective We investigated for quantitative EEG (QEEG) differences between Alzheimer's
disease (AD), dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) …
