A. Digital EEG is an established substitute for recording, reviewing, and storing a paper EEG record. It is a clear technical advance over previous paper methods. It is highly recommended. (Class III evidence, Type C recommendation). B. EEG brain mapping and other advanced QEEG techniques should be used only by physicians highly skilled in clinical EEG, and only as an adjunct to and in conjunct...

INTRODUCTION Previous studies of patients with unipolar depression have shown that early decrease of prefrontal EEG cordance in theta band can predict clinical response to various antidepressants. We have now examined whether decrease of prefrontal quantitative EEG (QEEG) cordance value after 1 week of venlafaxine treatment predicts clinical response to venlafaxine in resistant patients. METH...

Mild cognitive impairment (MCI) as a precursor of dementia with Lewy bodies (DLB) is the focus of recent research, trying to explore the early mechanisms and possible biomarkers of DLB. Quantitative electroencephalogram (QEEG) methods are able to differentiate early DLB from Alzheimer's disease (AD). The aim of the present study was to assess whether QEEG abnormalities, characterized by dominan...

OBJECTIVES An extensive neuroimaging literature on chronic pain demonstrates increased cerebral blood flow and metabolism consistent with increased neuronal activity in the structures comprising the "pain matrix"; furthermore, some of these regions have been shown to encode pain intensity. It is the objective of this study to demonstrate the feasibility of using quantitative electroencephalogra...

UNLABELLED Previous EEG studies attempted to examine violent behavior as homogeneous construct. Up to date, there is no other research studying Low-Resolution Brain Electromagnetic Tomography (LORETA) technique in psychopath offenders. OBJECTIVE To find electrophysiological differences specifically related to the psychopathy construct and independent of the violent behavior. The current inves...

This paper presents a mobile, easy-to-maintain wireless electroencephalograph (EEG) system designed for work with children in school environment. EEG data acquisition platform is small-sized, battery-powered high sampling rate that scalable to different channel numbers. The was validated study of live z-score neurofeedback training quantitative (zNF-qEEG) typical-reading and those developmental...

Objective: Quantitative electroencephalography (QEEG) is a well established method for evaluating brain functioning. Abnormal oscillatory activity measured with QEEG during resting state has been consistently reported in patients with schizophrenia. We aimed to examine whether resting state EEG is associated with 1 year outcome in patients with first episode psychosis (FEP). Method: Twenty five...

Objective: We investigated quantitative electroencephalography (qEEG) and clinical parameters as potential risk factors of severe cognitive decline in Parkinson's disease. Methods: We prospectively investigated 37 patients with Parkinson's disease at baseline and follow-up (after 3 years). Patients had no severe cognitive impairment at baseline. We used a summary score of cognitive tests as the...

UNLABELLED We report a descriptive analysis-interpretation of quantitative electroencephalography (QEEG) data for the metric of power in patients with tinnitus of the severe disabling type (N = 61). The results are based on a statistical analysis of the data compared to a normative database as calculated in Z scores, controlling for the factors of age, gender, IQ, and the like. METHOD We anal...

OBJECTIVE We examined how psychotropic medications affected quantitative EEG (qEEG) results among patients with a schizophrenia-spectrum disorder. METHODS The drugs were clustered into nine groups depending on their mechanism. We hypothesized that drugs would affect the relative power shown in qEEG results independently and investigated the effect of each drug group on relative power using mu...
