The authors assessed the psychological, neuropsychological, and electrocortical effects of human exposure to mixed colonies of toxigenic molds. Patients (N = 182) with confirmed mold-exposure history completed clinical interviews, a symptom checklist (SCL90-R), limited neuropsychological testing, quantitative electroencephalogram (QEEG) with neurometric analysis, and measures of mold exposure. ...

We report changes in quantitative electroencephalography activity in a male tinnitus patient when his tinnitus suddenly disappeared. Topographical illustration of the quantitative electroencephalography data showed beta foci in T3 and C4 with tinnitus, which resolved on spontaneous remission of the tinnitus. Comparison of the power spectra in the presence and absence of tinnitus revealed signif...

Electrical activity of each brain region is homeostatically regulated, resulting in predictable frequency composition of the background EEG. Replicated normative databases have established that the EEG power spectrum is independent of ethnic background. Artifact-free EEG evaluated relative to such norms displays few deviant values in healthy, normally functioning individuals. In subjects with p...

The aim of the study was to evaluate the effectiveness of individually tailored neurofeedback protocol for the reduction of anxiety which was diagnosed in a patient with suspected schizophrenia and TIA. The neuromarkers in Quantitative EEG (QEEG) and Event-related potentials (ERPs) were utilized in the construction of the protocol and the evaluation of the effectiveness of neurofeedback. A 54-y...

Schizophrenia is sometimes considered one of the most devastating of mental illnesses because its onset is early in a patient's life and its symptoms can be destructive to the patient, the family, and friends. Schizophrenia affects 1 in 100 people at some point during their lives, and while there is no cure, it is treatable with antipsychotic medications. According to the Clinical Antipsychotic...

OBJECTIVES Cardiac surgery involving cardiopulmonary bypass is associated with neurologic deterioration. Several interventions, including anesthetic techniques, have been designed to limit ischemic brain damage and have been evaluated in animals. Markers of neurologic injury may facilitate the assessment of these interventions in humans. DESIGN A blinded randomized prospective study comparing...

The aims of this double-blind study were to assess and compare the efficacy of quantitative electroencephalographic (QEEG) prefrontal theta band cordance in the prediction of response to 4-week, right, prefrontal, 1-Hz repetitive transcranial magnetic stimulation (rTMS) or venlafaxine ER in patients with major depressive disorder (MDD). Prefrontal QEEG cordance values of 50 inpatients (25 subje...

We read with great interest the article published by Fonseca et al. about the contribution of quantitative electroencephalographic (qEEG) analyses in the diagnosis of Alzheimer’s disease (AD)1. In this article, the authors concluded that the study of coherence and power in the qEEG showed a relatively limited accuracy, with respect to its application in the routine clinical practice. Beyond thi...

OBJECTIVE To investigate the reliability of several well-known quantitative EEG (qEEG) features in the elderly in the resting, eyes closed condition and study the effects of epoch length and channel derivations on reliability. METHODS Fifteen healthy adults, over 50 years of age, underwent 10 EEG recordings over a 2-month period. Various qEEG features derived from power spectral, coherence, e...
