qEEG: Quantitative EEG or Brain Map
At Dallas Brain Changers, prior to beginning neurofeedback, we utilize an important assessment tool called the qEEG, or Brain Map. This gives a snapshot image of what is going on in the brain that may be causing the symptoms the client is experiencing. The qEEG provides the best information for neurofeedback training, as it helps the clinician isolate where in the brain the issues may be arising from and which brain waves are affected.
The EEG patterns from individuals are compared to others of the same/similar age in a “normative” database. The subsequent report helps identify where the differences are and how significant these differences may be from the “normal” sample group. Within the test, there are hundreds of measurements. The results are interpreted and analyzed by a specialist, and treatment protocols are then devised. One measure tested with the qEEG is called coherence. In simple terms, coherence measures how well communication is occuring within the brain itself. There is constant communication occuring between different areas of the brain at all times. If two areas are not communicating well (too little or too much), it can interfere with the efficiency of overall brain function. A qEEG is one of the few tools available that help assess coherence.
Statistical analysis of the EEG compares your brain activity to a large sample of an age specific normal population. This analysis can help identify problems that relate to cognitive and executive function, mood, anxiety and attention. The qEEG, or brain mapping, has been of value in identifying disorders of biological origin, such as schizophrenia, dementias, hyperactivity and depression, brain atrophy and attention deficit disorders, as well as many other disorders, in both children and adults (minimum age for children is 5 yrs old).
