What is a quantitative electroencephalogram (QEEG) or brain map?


A qEEG (Quantitative Electroencephalogram) or Brain Map is an assessment tool to objectively measure and evaluate a person’s electrical brain activity or brain waves.

The assessment provides a detailed clinical report or “brain map” to look at the brain’s functionality and explain clients’ concerns and symptoms. The qEEG shows functional aspects of the individual’s brain, such as if the brain is underactive or overactive. Where there are abnormalities in brain activity patterns,  an frequently be responsible for certain disorders such as ADHDAnxietyPTSD, mood disorders and more.  The qEEG can show if an individual has too much too little brain activity and also how the different areas of the brain are communicating appropriately compared to an age matched reference. 

Brain maps are important aids in our patient evaluation and treatment planning process.

We know what cognitive or emotional functions each area of the brain performs and how that may manifest in symptoms for the client. With our previous knowledge and the brain map as a guide, we are able to evaluate treatment plans, protocols, and numbers of sessions needed. 

With this data we will have a comprehensive overview of the client overall neurocognitive and mental functioning. qEEG’s are done prior to starting any neurofeedback treatment. 

What is the process of a qEEG?

The qEEG process is painless. It involves wearing a head cap with electrodes attached to it.

These electrodes detect electrical impulses from your brain and send the signals to a computer for analysis.

The cap simply reads brain activity and gel is used to enhance electrode performance.

To establish a baseline, you will be asked to sit still for about 10 minutes with your eyes closed and then repeat the process with your eyes open.
