What is a QEEG?
A QEEG is a non-invasive, scientific, evidence based assessment tool
that is used to identify areas of dysregulation in a person’s brain
that are likely causing symptoms, such as sleep disturbance, emotional or
behavioural difficulties, or learning problems. A QEEG compares the person’s
brainwave profile to the norm for his or her age and gender. Because the brain
controls every aspect of learning, behaviour, mood and general functioning,
the brainwave profile correlates extremely well with the symptoms. Various
factors are investigated, which comprehensively contribute to greater understanding
of the cause of the symptoms and an effective plan for remediation.
A QEEG measures the electrical functioning of the brain and not the structure. This electrical activity is measured while the brain is at rest, and while cognitively involved in various tasks to ensure that the correct parts of the brain are engaged at the correct time.
This tool is not intended to be used in isolation or to replace the medical opinion of a physician, neurologist or other professional, but rather as part of a comprehensive assessment of functioning.
QEEG has “a level of specificity and sensitivity that is comparable to sonograms, blood tests, MRIs and other diagnostic measures commonly used in clinical practice.” (Thatcher, Moore, John et al, 1999).
What is the difference between a QEEG and a routine EEG?
A routine EEG is used primarily to diagnose epilepsy.
A QEEG is used to identify areas of the brain that cause inefficient processing in the brain. To analyse quantitatively, we use the data that is collected for a routine EEG. Therefore a routine EEG is done at the same time. Separate reports will be provided by Irene Masters, neurophysiologist, on the routine EEG and the QEEG findings. In QEEG reports, brainwave comparisons are presented as numbers, graphs, and colour coded brain maps.
