BACKGROUND Autistic spectrum disorders are a group of neurological and developmental disorders associated with social, communication, sensory, behavioral and cognitive impairments, as well as restricted, repetitive patterns of behavior, activities, or interests.The aim of this study was a) to analyze QEEG findings of autistic patients and to compare the results with data base; and b) to introdu...

OBJECTIVES The aim of this single-blind randomized crossover study was to evaluate specific effects of manual acupuncture on central and vegetative nervous system activity measured by quantitative electroencephalography (qEEG) and heart rate variability (HRV). DESIGN Twenty (20) healthy volunteers (mean: 25.2 +/- 3.6 years) were monitored simultaneously using a qEEG system and a 12-channel el...

Sleepiness is common after stroke, but in contrast to its importance for rehabilitation, existing studies focus primarily on the acute state and often use subjective sleepiness measures only. We used quantitative electroencephalography (qEEG) to extract physiological sleepiness, as well as subjective reports, in response to motor-cognitive demand in stroke patients and controls. We hypothesised...

The following pages represent a summary of many articles, papers, reviews and books on medications and the CNS function, and finally nearly 30 years of experience in clinical and research EEG. The difficulty in this area is the definitions of bands varies, the methods of analysis range from visual inspection of the raw EEG to quantitative measures, not all of which are clearly defined... and th...

Background: Quantitative EEG analysis incorporating the use of normative or reference database comparison has developed from being primarily a research tool into an increasingly widely used method for clinical neurophysiological evaluation. Method: A survey of several of the most widely used qEEG databases as well as issues surrounding the construction and use of these databases is presented, c...

PET relative metabolism was correlated with quantitative EEG in 9 schizophrenic patients. The PET metabolic regions of interest were the frontal lobes, thalamus and basal ganglia, and right and left temporal lobes. Significant positive correlations were seen for the frontal lobes and delta EEG power, and alpha power with subcortical metabolism. The physiologic plausibility of those correlations...

114 Recent research into fibromyalgia has suggested dysfunction in the central nervous system (CNS) as a possible contributor to this chronic pain condition. If changes in the CNS are involved in fibromyalgia, then dysfunctional brain activity should be present. This article specifically focuses on the brain wave activity in a group of fibromyalgia sufferers. In this study, 40 fibromyalgia suff...

Advances in technology recent years have made the use of quantitative electroencephalogram more accessible to clinicians. The incorporation normative databases QEEG studies and possibility detecting different electroencephalographic patterns patients with a given pathology, despite showing an apparent symptomatology homogeneity, make it interesting source information. relationship these possibl...

Photons are emitted during brain activity and when applied externally alter its functional connectivity during the resting state. In the present study we applied constant or time varying light (~10,000 lux) stimuli to one side of the skull and measured by photomultiplier tubes the photon density emitted from the opposite side of the skull along its two horizontal planes. Global quantitative ele...
