Quantitative EEG (QEEG)
Quantitative EEG, or QEEG, also known as a brain map, is a test that involves measuring electrical brainwaves on the surface of your head at 19 different sites, and then entering that data into a special computer program that quantifies it. Then the data from your brain is compared to many thousands of normal age and sex matched brains in a large database, and can then be expressed visually in pictures. This allows us to clearly see which parts of your brain are functioning normally, and which parts are under or over active, and by how much. Doing a QEEG of your brain allows us to “see” what is going on in your brain at a neuronal level. Doing a “Q” takes about 30 – 60 minutes depending on the patient, and is painless.
Brain waves occur at various frequencies, or Hertz, which means cycles per second. Some are fast, and some are slow. The classic names for these EEG bands are delta, theta, alpha and beta. There are clear norms for how much of each type of brain wave should be present in different areas of the brain.
A QEEG can be very helpful in deciding on brain treatment. QEEG signature patterns can help in diagnosing different types of anxiety, OCD, tinnitus, PTSD, ADD and ADHD, excess anger, depression, sleep disorders, chronic pain – and much more.
Once the brain diagnosis is confirmed, QEEG can help your doctor decide on which neurotherapy intervention, such as Neurofeedback or Transcranial Magnetic Stimulation would be appropriate to help treat it, and offers critical information on where to treat it. The efficacy of Neurofeedback and TMS depend on treating the right locations of the brain, and QEEG can help target those areas very accurately. Everyone’s brain is different. So doing a “Q” before starting neurotherapy is essential. After some treatments, follow up QEEG testing, along with symptom questionnaires, can confirm treatment results!
Doing QEEG-guided neurotherapy for brain disorders is very powerful, and can be used to help many people who have not responded to other traditional interventions, such as medications, or can be used to help patients get off medications. Neurotherapy treatment results are often long-lasting, so this allows us to literally change your brain to help improve your life at a very basic level. It can even be used for executive, student, and athletic peak performance. Proper brain function is essential to everything you do. There are very few things in life that are more important than a well-functioning brain. QEEG-guided neurotherapy can help you get to where you want to be.
