What is a QEEG?
QEEG is an FDA approved, evidence-based diagnostic tool that measures the speed and processing of brain function. It actually measure the brain's processing speed and overall brain function.
Much like a road map, brain maps show us not only which brain systems are out of balance but also where the imbalances are located. Only by using objective measures can the brain's processing and cognitive abilities be determined. QEEG allow us to determine what type of program an individual should undertake to correct brain based imbalances.
Imagine if you were in an accident and went to a hospital or doctor's office to find out the extent of injury you had sustained. What if, instead of sending you to x-ray, you were told it wasn't necessary to determine precisely where there might be break or even if you had a break. What if your entire legs or arms were instead placed in a cast (just to be safe), or worse what if the wrong leg or arm were placed in the cast because it could not be determined by talking to you where there might be a break, sprain or damage? Wouldn't you be a little alarmed if objective measures (x-rays) were not used prior to recommendations being made for treatment?
The qEEG is used by those in a professional practice for the following clinical applications: evaluating effects of medications and predicting medication response, head traumas, cognitive and psychiatric changes, neurodevelopment, neurotherapy, peak performance, and predicting protocols for training. (Gunkelman, J., n.d.)
QEEG reveals " . . . a level of specificity and sensitivity that is comparable to sonograms, blood tests, MRIs and other diagnostic measures commonly used in clinical practice." (Thatcher, R., Moore, R., John, R., Duffy, F., et. al.,1999)
This body of research supports that QEEG has a high level of reliability that is equal or superior to routinely used clinical tests such as mammograms, cervical screenings, blood tests, MRI and CAT scans. A comprehensive literature review in the Journal of Neuropsychiatry and Clinical Neurosciences reported,
"Of all the imaging modalities, the greatest body of replicated evidence regarding pathophysiological concomitants of psychiatric and developmental disorders has been provided by EEG and QEEG studies." (Hughes & John, 1999)
