Serial quantitative electroencephalography

Electroencephalography and Clinical Neurophysiology, 1979
Repeated EEG examinations are often used in diagnostically difficult cases to assess whether an EEG abnormality is progressive, regressive, or stationary. The conventional visual method is, however, poorly adapted to consider the variability when consecutive EEG recordings are compared.

Conventional and Quantitative Electroencephalography in Psychiatry

The Journal of Neuropsychiatry and Clinical Neurosciences, 1999
Electrical activity of each brain region is homeostatically regulated, resulting in predictable frequency composition of the background EEG. Replicated normative databases have established that the EEG power spectrum is independent of ethnic background.

Quantitative electroencephalography in amyotrophic lateral sclerosis

Electroencephalography and Clinical Neurophysiology, 1998
The authors evaluated quantitative EEG (QEEG) in patients with amyotrophic lateral sclerosis (ALS), in order to see if the confined cortical degeneration found in anatomical and functional examinations of central (rolandic) regions could give rise to abnormalities of cortical electrical activity.Eighteen patients with ALS were compared with 14 control ...

The Reliability of Quantitative Electroencephalography as an Indicator of Cerebral Ischemia

Anesthesia & Analgesia, 1995
The electroencephalogram (EEG) has been used to detect episodes of cerebral ischemia during various surgical procedures. Recently, computerized systems for recording and interpreting the quantitative EEG (QEEG) have been used by anesthesiologists because of their ease of application, clarity of display, and reported ability to identify ischemic EEG ...

Quantitative Electroencephalography in OCD Patients Treated with Paroxetine

Clinical Electroencephalography, 2003
The effectiveness of drugs that have a specific effect on the activity of the serotonergic neurotransmitter system has changed the outlook for patients suffering from obsessive-compulsive disorder (OCD). With a response rate of about 70% to such compounds and the great amount of brain imaging studies conducted over the past decades, an understanding of

Quantitative Electroencephalography (QEEG) and Neuropsychological Syndrome Analysis

Neuropsychology Review, 2001
The ideographic, syndrome analysis and the nomothetic, standardized test battery approaches to neuropsychological assessment are compared and contrasted within the context of advances in noninvasive technology readily available for use within the examiner's office.

Quantitative electro-oculography and electroencephalography as indices of alertness

Electroencephalography and Clinical Neurophysiology, 1998
Even though both electro-oculography (EOG) and EEG have been widely used for assessing alertness, the relationship between these two measures has not yet been clarified at various alertness levels. We estimated the frequencies of eye movements faster than 15 degrees/s (NoEM15) and EEG power at every 0.5 Hz step frequency point, quantitatively as well ...

Topographic Approaches in Human Quantitative Pharmaco-Electroencephalography

Neuropsychobiology, 2008
The scalp distribution of the quantitative EEG effects of neuroactive compounds was studied in a number of pharmaco-EEG investigations, in which comparable procedures for EEG recording and processing were applied: power spectral and amplitude analyses were combined in all studies. Topographic differentiations were observed.

THE APPLICATION OF REGRESSION ANALYSIS TO QUANTITATIVE ELECTROENCEPHALOGRAPHY IN MAN

Psychophysiology, 1967
ABSTRACTThe use of the Drohocki integrator to quantitate the area under the curve of the electroencephalogram (EEG) has provided useful information in earlier studies. However, difficulties arise in comparing data obtained with different types of EEG machines and integrators because of differences in the frequency spectra to which the machines respond.

Interoperator variability in quantitative electroencephalography.

Clinical and experimental neurology, 1992
The purpose of the study was to determine whether quantitative or discriminant analysis of the electroencephalograph (EEG) would vary significantly when the same EEG was analysed by 3 different operators. EEGs on 10 healthy volunteers were recorded on the Cadwell Spectrum AT 386, using the Electrocap (10-20 system). The EEGs were analysed independently,
