QEEG ANALYSIS
WHAT IS A QEEG?
Electroencephalography (EEG) is the measurement of electrical patterns at the surface of the scalp which reflect cortical activity, and are commonly referred to as “brainwaves”. Quantitative EEG (qEEG) is the analysis of the digitized EEG, and in lay terms this sometimes is also called “Brain Mapping”.
​
Quantitative Electroencephalography is a procedure that processes the recorded EEG activity from a multi-electrode recording using a computer. This multi-channel EEG data is processed with various algorithms, then digital data is statistically analyzed, sometimes comparing values with “normative” database reference values.
The processed EEG is commonly converted into color maps of brain functioning called “Brain maps”.
It is important to understand that a Quantitative EEG (QEEG) is not the same as a “clinical EEG” which is used in medical diagnosis to evaluate epilepsy or to determine if there is serious brain pathology, such as a tumor. The QEEG assessments we conduct are not intended to diagnose neurological disorders, nor intended to be used for any medical purpose whatsoever. It is not designed to diagnose tumors, epilepsy, or other medical conditions in a manner like an MRI or CAT scan. The Quantitative EEG evaluates the manner in which a particular person’s brain functions from an efficiency standpoint, and assists in directing the Neurotherapy treatment. The QEEG neurometric statistical analysis allows us to know, in many cases with a 95% degree of accuracy, that someone has functional brain inefficiencies. The QEEG also provides valuable input that may assist in the diagnosis of various psychiatric-psychological conditions; but it is a fundamental principle that one method alone should not be used to make a diagnosis or for decision making. Therefore, a QEEG alone will not be used for diagnostic purposes. You should recognize that the QEEG evaluation is noninvasive and no electrical current is put into the brain. However, the electrode cap is tight fitting and can become uncomfortable before the evaluation (and full cap training) is over. In order to obtain good electrode connections for assessment and training, it is also not unusual for the skin to be scratched in tiny areas under a few of the electrodes.
Unless it is specifically requested (with an additional evaluation cost) a neurologist or medical doctor will not be reviewing the EEG data for presence of seizures or other neurological disorders. If you suspect a seizure disorder, or any other neurological disorder, you are strongly encouraged to see a neurologist prior to seeking Neurotherapy services.
