Quantitative EEG analysis methods and clinical applications

In a previous paper Valdes et al. The increased diagnostic accuracy of high resolution spectral methods is demonstrated by means of receiver operator characteristic ROC curve analysis. Procedures are introduced to avoid type I error inflation due to the use of more variables in this type of procedure. This is a preview of subscription content, access via your institution.

This has provided the impetus to the field of quantitative EEG (qEEG) analysis. Digital EEG recording and leaps in computational power have indeed spawned a​.


Quantitative EEG analysis methods and clinical applications

Quantitative electroencephalography QEEG is a modern type of electroencephalography EEG analysis that involves recording digital EEG signals which are processed, transformed, and analyzed using complex mathematical algorithms. QEEG has brought new techniques of EEG signals feature extraction: analysis of specific frequency band and signal complexity, analysis of connectivity, and network analysis. The clinical application of QEEG is extensive, including neuropsychiatric disorders, epilepsy, stroke, dementia, traumatic brain injury, mental health disorders, and many others. In this review, we talk through existing evidence on the practical applications of this clinical tool. We conclude that to date, the role of QEEG is not necessarily to pinpoint an immediate diagnosis but to provide additional insight in conjunction with other diagnostic evaluations in order to objective information necessary for obtaining a precise diagnosis, correct disease severity assessment, and specific treatment response evaluation.

Quantitative electroencephalography power and coherence measurements in the diagnosis of mild and moderate Alzheimer's disease. The procedures consisted of clinical-neurological, cognitive and behavioral analyses and the qEEG absolute power and coherence. Logistic multiple regression models were constructed and those only showing variations in the qEEG frontal alpha coherence and left frontal absolute theta power showed an accuracy classification

On the application of quantitative EEG for characterizing autistic brain: a systematic review

Language: English Portuguese. The primary diagnosis of most cognitive disorders is clinically based, but the EEG plays a role in evaluating, classifying and following some of these disorders. There is an ongoing debate over routine use of qEEG. The primary diagnosis of most cognitive disorders is clinically based but the EEG plays a role in evaluating, classifying and following some of these disorders. The EEG is a widely accepted method for evaluating cortical information processing and neurophysiologic changes that occur during unconsciousness and varying states of conscious awareness.

Metrics details. Patients with brief depressive episodes and concurrent rapidly fluctuating psychiatric symptoms do not fit current diagnostic criteria and they can be difficult to diagnose and treat in an acute psychiatric setting. We wanted to study whether these patients had signs of more epileptic or organic brain dysfunction than patients with depression without additional symptomatology.

The Role of Quantitative EEG in the Diagnosis of Neuropsychiatric Disorders

Most of these techniques have demonstrated research uses, but few have been shown to have clinical applications that actually impact patient care. Substantial problems exist that can interfere with routine clinical applications. These include a variety of artifacts, confounding clinical problems, diversity of techniques and statistical issues.

Autism-Spectrum Disorders ASD are thought to be associated with abnormalities in neural connectivity at both the global and local levels. Quantitative electroencephalography QEEG is a non-invasive technique that allows a highly precise measurement of brain function and connectivity. This review encompasses the key findings of QEEG application in subjects with ASD, in order to assess the relevance of this approach in characterizing brain function and clustering phenotypes. QEEG studies evaluating both the spontaneous brain activity and brain signals under controlled experimental stimuli were examined. Despite conflicting results, literature analysis suggests that QEEG features are sensitive to modification in neuronal regulation dysfunction which characterize autistic brain.

Она шагнула вперед, но и там была та же пустота. Сигналы продолжались. Источник их находился где-то совсем близко. Сьюзан поворачивалась то влево, то вправо.
