objective: to obtain abnormalities in quantitative electroencephalography qeeg) and to observe connectivity between electrodes in children with asperger disorder. method: in this study, spectrogram criteria and coherence values are used as a tool for evaluating qeeg in 15 children with asperger disorder (10 boys and 5 girls aged between 6 to 11 years old) and in 11 control children boys and 4 g...

objective: to evaluate the brain signals in children with autism disorder in many different conditions of quantitative electroencephalography (qeeg) recordings in order to highlight abnormalities and to characterize this group. method: in this study, spectrogram was used as a tool for evaluating qeeg in 15 children with autism disorders (13 boys and 2 girls aged between 6 to 11 years old) and i...

Interventions for improvement of cognitive problems in patients with traumatic brain injury (TBI) include electroencephalography biofeedback, also known as neurofeedback. Quantitative electroencephalography (QEEG) patterns are assessed in TBI patients and then compared to a database obtained from a normative population. Deviations in QEEG patterns from the normative group are the basis for an i...

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...

Reliability and validity are statistical concepts that are reviewed and then applied to the field of quantitative electroencephalography or qEEG. The review of the scientific literature demonstrated high levels of split-half and test re-test reliability of qEEG and convincing content and predictive validity as well as other forms of validity. qEEG is distinguished from nonquantitative EEG (“Eye...

Quantitative electroencephalography (QEEG) is the technique whereby brain electrical activity in individuals is recorded as they sit quietly with their eyes closed. The electrical activity is quantified with a variety of statistical measures to characterize the huge variation in combinations of emissions from the brain. Neuroscience research has demonstrated that such resting brain activity mea...

OBJECTIVE Quantitative electroencephalography (qEEG) has been increasingly used to evaluate patients with attention deficit hyperactivity disorder (ADHD). The aim of this study was to assess the correlation between qEEG data and symptom severity in patients with ADHD. METHODS Fifteen patients with ADHD and 20 healthy controls (HCs) were recruited. Electroencephalography was assessed in the re...

Neuroplasticity is the ability of brain to change structurally and functionally in compensation for changes related age or disease. In elderly people, most common neuroplasticity problem mild cognitive impairment (MCI). MCI a syndrome defined as decrease function that not appropriate person's educational level. One way minimize progress deterioration by doing physical exercise, such walking. th...

The effect of early antiretroviral medication with zidovudine on neurophysiological functions was evaluated in subjects with asymptomatic HIV-1 infection. Patients were recruited participants of a larger double-blind randomised placebo-controlled treatment trial with zidovudine (Concorde). The main outcome measures included: quantitative electroencephalography (QEEG), auditory event-related pot...

Objective: We investigated quantitative electroencephalography (qEEG) and clinical parameters as potential risk factors of severe cognitive decline in Parkinson's disease. Methods: We prospectively investigated 37 patients with Parkinson's disease at baseline and follow-up (after 3 years). Patients had no severe cognitive impairment at baseline. We used a summary score of cognitive tests as the...
