What is a Quantitative EEG Brain Map (QEEG)
Quantitative Electroencephalography (QEEG) Brain Map is an assessment tool which measures the electrical activity of a person’s cerebral cortex or brain. A person’s brainwaves are digitally recorded at the surface of the scalp and then compared to FDA approved normative databases of normal populations stratified by age and sex. The QEEG brain map is then used to aid in the diagnosis of mental health conditions via the use of the statistical analysis of a person’s electrical brainwave activity. Years of research has determined what a normal brain functioning looks like.
A QEEG Brain Map is a painless, non-intrusive procedure in which a 19 channel EEG cap is placed on a person’s scalp. Generally two recordings are administered, an eyes open recording and an eyes closed recording.
After muscle and eye movements are removed from the recordings, the data is then analyzed in a process called normative databases. A person’s brainwave activity is then compared to normal population based upon the age and sex of a person. This process produces Brain Maps. The maps depict both normal and abnormal areas of the brain as well as revealing the brain’s ability to communicate to different lobes. The goal of normal brain functioning is to have the brain balanced and communicating in concert.
The following is an example of a Surface Lobe QEEG Brain Map:
The statistical information provided by the brain maps provide the information necessary to scientifically design protocols and precisely target the areas of a person’s brain that are causing problems. All treatment in Dr. Blume’s practice is guided by a QEEG Brain map. In this way, there is no guessing and the process is entirely based upon science and brain research.
