OBJECTIVE To analyze the frequency and severity of subclinical cerebral complications associated with coronary artery bypass grafting (CABG). DESIGN A prospective controlled study using preoperative and postoperative magnetic resonance imaging (MRI) of the brain, quantitative electroencephalography (QEEG), and detailed neuropsychological and neurologic examinations as potentially sensitive in...

BACKGROUND The aim of this study was to search for predictors of acute side effects of stimulant medication in pediatric attention deficit/hyperactivity disorder (ADHD), emphasizing variables from quantitative electroencephalography (QEEG), event-related potentials (ERPs), and behavior data from a visual continuous-performance test (VCPT). METHODS Seventy medication-naïve ADHD patients aged 7...

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...

OBJECTIVE qEEG investigations present differences in the comparison of schizophrenic patients and healthy examinees, as well as of depressive patients and healthy controls. The comparison of "positive" and "negative" schizophrenia also presents differences in the qEEG parameters. Changes in qEEG are various in these studies, but not always consistent. In this research we wanted to compare "posi...

Introduction: An investigation into the QEEG parameters of effective auditory memory for paragraphs was conducted employing sixty normal right-handed subjects. Method: Four stories were read to the subjects. The subjects engaged in an immediate thirty-second quiet recall period, which was followed by the subjects recalling the stories outloud. A delayed recalled assessment (about forty-five min...

Background. Mild closed head injury (MHI) is a major problem in our society. Traditional methods of treatment such as cognitive rehabilitation or behavioral training are time consuming, expensive, and of questionable effectiveness. Anecdotal reports indicate that neurofeedback can remediate the symptoms of MHI in a rapid and cost effective way. The purpose of this study is to evaluate whether q...

Thalamocortical dysrhythmia is a shared hallmark of numerous neurodivergent conditions. Restricted environment stimulation therapy (REST) flotation causes desirable neural shifts in anxious or depressed populations towards classically defined healthy spectra. In this exploratory investigation, chronic lower back pain patients were randomly assigned to the experimental condition, six 1-hr REST s...
