Evaluation and Assessment

Neurofeedback treatment is preceded by an objective assessment of brain activity. Before a client has any brainwave training, a Quantitative Electroencephalography (qEEG) is done. The procedure processes the recorded EEG activity from a multi-electrode recording using a computer.

For the mapping, the patient sits in a comfortable chair while the technician cleans the earlobes and 19 spots on the scalp to ensure conductivity. The technician then clips  tiny wires to the ears and pastes sensors to the scalp. The neuromapping computer program is run twice, first with eyes open, then with eyes closed, and takes 1 1/2 to 2 hours.

The digital data is statistically analyzed, comparing the values with normative database reference values. The processed EEG is 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.

QEEG brain mapping provides a highly individualized evaluation and assessment for treatment planning.

Neurofeedback Frequently Asked Questions:

(click on + for answer)
What can I expect?

During neurofeedback, generally one to two sensors are first placed on the scalp and a set of ear clips are attached. They are connected to sensitive electronics and computer software that detect, amplify, and record specific brain activity. The software processes the signal and provides the proper feedback in visual and audio form.

How long does each neurofeedback session take?

Sessions usually last 30-45 minutes, but this is determined per individual and will likely start with less and increase over time.

How frequently should the sessions be scheduled?

In the initial stages of learning, the sessions should be regular and frequent. This means two or three sessions each week.

How will I feel after a session?

Depending on what  frequency is being trained, some patients report feeling more relaxed and focused after a session, others may not feel any differently.

Are the results of neurofeedback permanent?

According to research over the past 40 years, the brain will continue to use its new capabilities.  Stress or a life-changing event like divorce may retrigger symptoms, but fewer neurofeedback sessions are needed to return brain efficiency.

Are there any contraindications for neurofeedback?

There are no known contraindications.

Is biofeedback the same as neurofeedback?

Biofeedback uses technology to quantify physiological parameters such as heart rate, blood pressure, skin temperature and muscle tension. Patients consciously change their physiciologic state until the sensors indicate that the parameters have improved to a more acceptable range.

Neurofeedback is a passive intervention with electrodes attached to certain areas of the scalp to monitor brainwave patterns.  It uses realtime displays of electroencepholography to illustrate brain activity, often with a goal of controlling central nervous system activity, with measurements displayed using video displays and sound.
