OBJECTIVE This study assessed the quantitative electroenchephalographic (QEEG) absolute power and coherence differences between a group of patients with bipolar I mood disorder (BMD I) and a group of patients with schizophrenia. We also examined the correlation between QEEG measures and family history of BMD. METHOD Using the National Institutes of Mental Health (NIMH) Global Rating Scale, we...

UNLABELLED Anxiety is defined as a subjective sense of worry, apprehension, fear and distress. When severe, it can affect a child's thinking, decision-making ability, perceptions of the environment, learning and concentration. Basal instability in cortical arousal, as reflected in measures of quantitative electroencephalography (qEEG), is common in most of the anxiety disorders. SUBJECTS AND ...

In 1954 and 1960 Koenig and his colleagues described the remarkable similarities of spectral power density profiles and patterns between the earth-ionosphere resonance and human brain activity which also share magnitudes for both electric field (mV/m) and magnetic field (pT) components. In 2006 Pobachenko and colleagues reported real time coherence between variations in the Schumann and brain a...

Current criteria identifying patients with ultra-high risk of psychosis (UHR) have low specificity, and less than one-third of UHR cases experience transition to psychosis within 3 years of initial assessment. We explored whether a Bayesian probabilistic multimodal model, combining baseline historical and clinical risk factors with biomarkers (oxidative stress, cell membrane fatty acids, restin...

Neurofeedback (NF) training has been employed as a therapeutic method in substance-dependence disorder over the last three decades. The purpose of the present study was to examine the effectiveness of this method on improvement of comorbid neuro-psychological syndromes in opioid-dependence disorder. Psychopathological and craving dimensions and brain activity signals of 20 opioid dependent pati...

UNLABELLED Quantitative electroencephalography (QEEG) has been proved as a powerfully tool for prediction of the stage of residual functional disable. For predictive value of QEEG, individual profile of every patient is most important. It has been demonstrated that Index of brain symmetry (BSI) present specific asymmetry of power spectra between two brain hemispheres and it has been normalized ...

Epstein (1974a, 1986) and McCall (1988; McCall, Meyers, Hartman, & Roche, 1983) presented discrepant findings regarding the presence ofstages in brain arid.&ognitive maturation, as described in Piagetian theory. This article questions whether their variables (e.g., skull circumference and global mental test scores) are appropriate indices from which to make such conclusions. Evidence from direc...

The primary diagnosis of most cognitive disorders is clinically based, but the EEG plays a role in evaluating, classifying and following some of these disorders. There is an ongoing debate over routine use of qEEG. Although many findings regarding the clinical use of quantitative EEG are awaiting validation by independent investigators while confirmatory clinical follow-up studies are also need...

Objective This study compares the complementary information from semi-quantitative EEG (sqEEG) and spectral quantitative (spectral-qEEG) to detect life-long effects of early childhood malnutrition on brain. Methods Resting-state EEGs ( N = 202) Barbados Nutrition Study (BNS) were used examine protein-energy (PEM) middle adulthood outcomes. sqEEG analysis was performed Grand Total (GTE) protocol...

objective: the aim of this study was to compare the qeeg of adolescents affected by bipolar ii disorder with age and gender matched healthy controls, and to extract the characteristics of the alpha frequency band to better understand this disorder. methods: twenty one adolescents affected by acute episodes of bipolar ii disorder (bmd ii), both hypomanic and depressive episodes, were selected vi...
