Objectives: To study the relationship between magnetic resonance imaging (MRI) T2 relaxation time and the power spectrum of the electroencephalogram (EEG) in long-term follow up of traumatic brain injury. Methods: Nineteen channel quantitative electroencephalograms or qEEG, tests of cognitive function and quantitative MRI T2 relaxation times (qMRI) were measured in 18 mild to severe closed head...

Electroencephalography (EEG) can be a valuable technique to assess electrophysiological changes related to dementia. In patients suspected of having dementia, the EEG is often quite informative. The sensitivity of the EEG to detect correlates of psychiatric disorders has been enhanced by means of quantitative methods of analysis (quantitative EEG). Quantitative features are extracted from, at l...

Quantitative electroencephalogram (qEEG) monitors are often used to estimate depth of anesthesia and intraoperative recall during general anesthesia. As with any monitor, the processed numerical output is often misleading and has to be interpreted within a clinical context. For the safe clinical use of these monitors, a clear mental picture of the expected raw electroencephalogram (EEG) pattern...

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...

Electroencephalography (EEG) is a noninvasive, widely available, and relatively inexpensive test that can help exclude or identify structural or functional factors contributing to psychiatric syndromes. This article defines the clinical usefulness of EEG in evaluating neuropsychiatric disorders, emphasizing the complementary nature of the visually inspected standard EEG (SEEG) and the computera...

Although several studies have revealed the EEG alterations in AD and TBI patients, the influence of APOE (apolipoprotein E) genotype in EEG at the early stage of TBI has not been reported yet. We have previously studied EEG alterations caused by TBI among different APOE genotype carriers. In this study, we firstly investigated the relationship between APOE polymorphisms and quantitative EEG (QE...

OBJECTIVE To investigate the relationship between quantitative EEG (QEEG) scores and "complicating factors" (psychopathology, true pharmacoresistance, neurological symptoms) in idiopathic generalised epilepsy (IGE). METHODS 35 newly referred, newly diagnosed, unmedicated IGE patients were collected in a prospective and random manner. Standard neuro-psychiatric and EEG examination was done. Th...

BACKGROUND The purpose of this study was to explore the possible difference in the electroencephalogram (EEG) pattern between euglycemia and hypoglycemia in children with type 1 diabetes (T1D) during daytime and during sleep. The aim is to develop a hypoglycemia alarm based on continuous EEG measurement and real-time signal processing. METHOD Eight T1D patients aged 6-12 years were included. ...

Electroencephalography (EEG) is an established measure in the field of brain resting state with a range of quantitative methods (qEEG) that yield unique information about neuronal activation and synchronization. Meanwhile, in the last decade, functional magnetic resonance imaging (fMRI) studies have revealed the existence of more than a dozen resting state networks (RSNs), and combined qEEG and...

Background: Transcranial Photobiomodulation (t-PBM) is a current, innovative method that used in the therapy of many neurological and psychological diseases. Its mechanisms action have been investigated most well described ways are its effects on mitochondrial function heat/light-activated ion channels neurons membrane. It has suggested increase cerebral blood flow alterations membrane dominant...
