What is a Quantitative Electroencephalograph?
Quantitative Electroencephalograph (QEEG) is the measurement, using digital technology, of electrical patterns at the surface of the scalp which primarily reflect cortical activity or “brainwaves”. A multi-electrode recording of brain wave activity is recorded and converted into numbers by a computer. These numbers are then statistically analysed and can be converted into a colour map of brain functioning. What are the advantages of QEEG in comparison to routine EEG’s? The amount of data generated by multi-electrode recording is so enormous it is difficult for clinicians to interpret all the data. QEEG’s address this data analysis and summarisation of data in the form of coloured topographic maps of the brain, spectral analysis and graphs. Other advantages are: * Data Base Comparisons A patient’s/client’s performance can be statistically compared to that of a large population data base. Such comparisons allow the clinician to determine whether or not brain functioning is abnormal, to w
