Functional EEG Analysis

What is a qEEG?

Quantitative Electroencephalography (qEEG) 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. The 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”. The EEG and the derived qEEG information can be interpreted and used by experts as a clinical tool to evaluate brain function, and to track the changes in brain function due to various interventions such as neurofeedback or medication. Quantitative Electroencephalography (qEEG) processing techniques and the use of modern analytic software to process the EEG/qEEG gives us the ability to view the dynamic changes taking place throughout the brain during a cognitive processing task. This novel approach can be used to assist us in determining which areas of the brain are engaged and processing efficiently.

Uses

It is typical of traditional western medicine to assess for diagnosis and treatment via medication. This novel approach can be used to assist us in determining which areas of the brain are engaged and processing efficiently. The results are useful in guiding various forms of treatment, including neurofeedback, biofeedback, diet, medication and life style interventions.

What is involved?

This takes 2 hours to complete. Preparation includes having a good night sleep before the evaluation and eating a healthy meal that includes protein prior to arrival at the office. You are asked to wash your hair several times with a pH neutral shampoo and to not use any conditioner or hair treatments following. An EEG tracks and records brain wave patterns. The electrodes analyze the electrical impulses in the brain and send signals to a computer that records the results.The test involves having a cap placed on your head that contains sensors that will read the electrical output of your brain. These brain waves are recorded in three conditions: eyes opened, eyes closed and during the task (22 minutes). You are given opportunities for breaks, as needed. The test is non-invasive and just requires that you sit in a chair.
