Variable contributions of state and trait to the electroencephalographic (EEG) signal affect the stability over time of EEG measures, quite apart from other experimental uncertainties. The extent of intraindividual and interindividual variability is an important factor in determining the statistical, and hence possibly clinical significance of observed differences in the EEG. This study investi...

Cognitive decline is common with the progression of Parkinson's disease (PD). Different candidate biomarkers are currently studied for the risk of dementia in PD. Several studies have shown that quantitative EEG (QEEG) is a promising predictor of PD-related cognitive decline. In this paper we briefly outline the basics of QEEG analysis and analyze the recent publications addressing the predicti...

Background: We aim to assess the role of quantitative electroencephalography (QEEG) derived indices predict post-stroke disability. Methods: included observational studies (sample-size≥10) patients with stroke who underwent EEG and a follow-up outcome assessment was available either in form modified Rankin scale (mRS) or National Institute (NIHSS) Fugl-Meyer (FMA). QEEG analyzed were delta-alph...

Abstract Background Quantitative electroencephalogram (QEEG) is a tool that uses computer to analyze brain activity monitored by (EEG) according measurements such as frequency, amplitude, and slope. The purpose of this study was understand the current situation QEEG utilization in China further compare situations among different regions levels hospitals. Methods An online questionnaire comprisi...

Abstract Recent advances in computer technology have made it possible to perform prolonged digital continuous video EEG monitoring of many critically ill patients simultaneously. Recent studies using continuous EEG monitoring (cEEG) have found that these patients, especially those with coma, acute brain injury, or prior clinical seizures, often have nonconvulsive seizures (NCSz), and that these...

Introduction: There have been multiple explorations for the finding of biological markers of suicide. Some studies indicated the association of neurophysiological markers with suicidal ideation (SI). In previous studies, antidepressant treatment-emergent SI was associated with theta value in midline right frontal region, and pretreatment assessment of frontal quantitative EEG (QEEG) may be asso...

Measuring neuronal activity with electrophysiological methods may be useful in detecting neurological dysfunctions, such as mild traumatic brain injury (mTBI). This approach may be particularly valuable for rapid detection in at-risk populations including military service members and athletes. Electrophysiological methods, such as quantitative electroencephalography (qEEG) and recording event-r...

Abstract Background Headache is one of the most common neurological symptoms reported in adolescence. The value electroencephalography (EEG) diagnostics patients with headache controversial; however, quantitative EEG (QEEG) can clarify pathophysiology headache. Aim study was to assess QEEG and daily habits adolescents or without a clinical history (according answers screening questionnaire), id...
