Seventy-one patients with recurrent migraine headaches, aged 17-62, from one neurological practice, completed a quantitative electroencephalogram (QEEG) procedure. All QEEG results indicated an excess of high-frequency beta activity (21-30 Hz) in 1-4 cortical areas. Forty-six of the 71 patients selected neurofeedback training while the remaining 25 chose to continue on drug therapy. Neurofeedba...

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...

OBJECTIVE Adjustment disorder (ADJ) is a common diagnosis. However, it is difficult to distinguish ADJ from other major Axis I disorders, such as major depressive disorder (MDD). The aim of this study was to determine the distinguishing neurophysiological characteristics between ADJ and MDD using quantitative analysis of an electroencephalogram (QEEG). METHODS The study included 30 patients w...

Significant changes in topographic quantitative EEG (QEEG) features were documented during induction and emergence from anaesthesia induced by the systematic administration of sevoflurane and propofol in combination with remifentanil. The goal was to identify those changes that were sensitive to alterations in the state of consciousness but independent of anaesthetic protocol. Healthy paid volu...

Background: A quantitative EEG (qEEG) study was performed to investigate the cerebral bioavailability of Silexan. Method: Twenty-four male and female healthy volunteers between 20 and 62 years of age were eligible for participation and received 160 or 80 mg/day Silexan or placebo in randomised order according to a 3-way crossover design. Treatment phases of 14 days were separated by 14-day wash...

OBJECTIVE We investigated frontal quantitative EEG (QEEG) as predictor of changes in suicidal ideation (SI) during SSRI treatment in major depressive disorder (MDD). METHOD Eighty-two subjects meeting DSM-IV criteria for MDD entered an 8-week, prospective, open-label treatment with flexible dose SSRIs and completed at least 4 weeks of treatment. We assessed MDD severity with the 17-item Hamil...

The electroencephalogram (EEG) is well-suited for continuous brain monitoring in neurological patients in the ICU, since the EEG is very sensitive for potential risks like ischemia and (non-convulsive) seizures [1]. However, to allow real-time computer assisted interpretation of the EEG, quantitative EEG (qEEG) and an adequate presentation of the data are required. This paper describes the impl...

Background: Identifying mental disorder biomarkers is one of the leading goals of the clinical science. Objectives: This study aimed to provide an artificial intelligence based solution and software program to diagnose the type and severity of mental disorders according to the quantitative electroencephalogram (QEEG) of patients. Materials and Methods: The QEEG data collected from 45 patients ...

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...

One year after a left posterior and thalamic stroke, a 52-year-old male participant was treated with 14 weeks of theta reduction neurofeedback training. Imaging studies revealed left temporal, parietal, occipital, and bilateral thalamic infarctions along the distribution of the posterior cerebral artery. Neuropsychological testing demonstrated severe verbal memory, naming, visual tracking, and ...
