Brain Mapping
We utilize an advanced neurological technology called a QEEG which produces a brain map that allows us to quantify the power, amount, distribution and ratio of various brain waves. To conduct the test, we place a cap on the individual’s head. The cap contains sensors that measure brainwaves of various frequencies.

The Quantitative EEG Neurofeedback Test Shows Us How The Brain Is Functioning
Delta Frequency – this is slowest frequency which is dominant when we sleep. If there is too much activity in the delta frequency, there are problems with motivation, the ability to focus and maintain attention. ADD sufferers will exhibit heavy activity in this frequency.
Theta Frequency – is a slow frequency that is present between sleep and wakefulness. Too little activity can lead to hyperactivity. However, too much activity can lead to inattentiveness.
Alpha Frequency – is one of the brain’s most important frequencies because it is a medium frequency that allows the individual to feel relaxed but alert. It enables individuals to accomplish tasks easily. Reduced amounts of alpha frequency cause worry, insomnia and an inability to effectively complete tasks which are common complaints of ADD sufferers.
Beta Frequency – is a medium fast frequency which is dominant when we are concentrating. We use this frequency to process information, problem solve and make solid judgments. Reduced activity in this area is associated with the ADD symptoms of inability to sustain attention and complete tasks.
High Beta Frequency – is a fast frequency. It is used when we process high level information. A good memory comes from a healthy level of high beta frequency. An elevated level of high beta causes hyperactivity and distractibility. Healthy individuals have a balanced level of activity in each of the frequencies. Excessive or severely decreased levels cause problems with attention, hyperactivity and mood regulation.

The red indicates excessive brain wave abnormalities in the beta and high beta frequencies. This caused the child to exhibit symptoms of distractibility and hyperactivity.
