Quantitative EEG, or “brain mapping” is a way of assessing the operation and functionality of the client's brain with the comparison of normative and clinical databases, and the processing of 20 minutes of brainwaves (EEG) recording. EEG is the measurement, using digital technology, of electrical patterns at the surface of the scalp which primarily reflect brainwave activity on the cortex (the “bark” of the brain). Neurotherapists use this knowledge to adjust cerebral function towards ideals with operant conditioning, counseling, and neuromodulation. Brain mapping is analyzing the electrical activity or "brainwaves."
The procedure is a three-part process, which entails:
Initial visit and intake, including 20 minutes of EEG recording;
During this process, we read and understand the "raw data," (the “squiggles” that are the brainwaves). Then, we remove all "artifact" (eye movements, much muscle tension, etc.).
The report work-up include the consultation of between 2-3 databases, depending on the client’s desire and clinician’s recommendations. The final report is approximately 40 pages in length, complete with summary page, explanatory pictures, graphics, and terminology that is accessible for the layperson, yet true to scientific form. The composition of the report often entails 3-5 hours of additional research. It may be recommended that the qEEG be combined with other medical, psychological and neuropsychological data to best aid the patient.
Dr. Tiff Thompson and Dr. Nicholas Dogris are certified Diplomates in Quantitative EEG, granted by the Quantitative EEG Certification Board. Tiff has worked as a neurodiagnostician in the medical field, and now in EEG biofeedback and quantitative EEG. Dr. Tiff and Dr. Dogris are experienced and qualified in the realm of interpreting raw EEG and using the results to assess clients and devise data-driven protocols, specific to the client’s needs.
Three databases consulted:
SKIL is a normative database that allows normative analysis of an individual's EEG to healthy, motivated adults, teens, & children. SKIL software began with the Department of Defense and NASA-sponsored research at UCLA, the Department of Veteran’s Affairs, and United States Air Force facilities in the 1980s and grew into product used by a community of clinical professionals and scientists from around the world who perform neurobehavioral interventions to treat patients and clients under multiple care classifications including psychiatric, neurological, psychological, primary, and academic. This is one of three normative and/or clinical databases that we use that entails advanced artifact management, task comparisons, , single-Hz customizable bands, with both background and transient analysis, on numerous parameters (e.g., coherence, phase lag, magnitude unity, and comodulation) in Referential, Laplacian, and Brodmann montages.
NeuroGuide Deluxe is the most informative and comprehensive Conventional EEG and QEEG analysis system available. This robust neurofeedback and qEEG system is an important component of this practice and is very much the gold standard in brain mapping.
The Thought Technology software is used when taking the Clinical QEEG. The Clinical qEEG (or Quick Q) is a qEEG that is based on a database taken from Dr. Paul Swingle’s Vancouver Clinic—this is different than other normative databases because the clients surveyed were not screened to ensure they were without pathologies or other disorders. The Quick Q uses five sites on the head and watches alpha attenuation with eyes open – eyes closed transition, changes in EEG when under task, symmetry between left and right frontal hemispheres, and theta / beta ratio, among other things. The clinical qEEG is great to use in conjunction with other qEEGs, but is not used in this practice for diagnostic purposes solely.
No, the procedure is completely painless.
No! The EEG recording is completely non-invasive.
Yes. You should limit fluid and food intake 2 hours before the test.
DO NOT DRINK ALCOHOL FOR AT LEAST 24 HOURS PRIOR TO THE TEST.
Approximately 30 minutes. The length of the test depends on how still and alert you can remain during testing. The preparation for the test will take approximately 5 minutes, therefore, the total time in office is about 35 minutes, we book an hour for the process.
Have a good night’s sleep the evening before. On the morning of the test wash and dry your hair thoroughly.
DO NOT USE HAIR SPRAY, MOUSSE, ETC. These products will make the scalp slick and the electrodes will not stick. Dry your hair completely and do not braid it.
Limit caffeine intake to 1 cup of coffee or tea 2 hours prior to the testing and try not to smoke tobacco.
Follow your doctor’s instructions. He may want you to discontinue some or all medications. Do not take any over the counter medications such as aspirin, antihistamines, ibuprofen, Tylenol, nasal sprays, cough medicine, allergy medication, analgesics, herbs, neutraceuticals, food supplements, amino acids, or other related products. If you are in doubt please call your doctor’s office.
Also, do not take any street drugs by any means (smoke, injection, orally, etc.) for several days before the test. If you do, the test will need to be cancelled.
Thank you for your cooperation; and I look forward to working with you.
