Quantitative EEG

Quantitative EEG (qEEG) is a simple, painless, non-invasive procedure that detects brain activity and allows our clinicians to record how the neurons in your brain function and communicate with one another.

A qEEG is a diagnostic tool that measures electrical activity in the form of brain wave patterns, sometimes referred to as “brain mapping.”

Brain waves are the electrical impulses generated when the neurons in your brain communicate with one another. Brain waves can reveal important information about your overall brain function, including stress levels, emotions, and thought patterns. A qEEG can reveal brain wave patterns that are associated with anxiety, cognitive inflexibility, and impulsivity, among other symptoms.

What happens during a qEEG test?

During a qEEG data collection, our technician places a special cap on your head with sensors applied to your scalp. We use a 19-channel assessment that looks at brainwaves from 19 sites on the scalp simultaneously. The data is recorded with your eyes opened, your eyes closed, and then while performing a simple recognition task.

The recording collects data for approximately 42 minutes to look at the brain waves in the three different activities. The information is sent from the sensors to a computer and Data is saved. IMBS then uploads your data for analysis with our trusted partners.


I had a qEEG performed at IMBS and I could not be more satisfied. Everyone involved was transparent about the procedure and the process was easy. I would gladly recommend IMBS to others.”


How often should I attend a qEEG session?

Unlike biofeedback and neurofeedback, the qEEG session is not a repetitive therapy. It is an information-collecting experience, taking approximately two hours to complete from start to finish. The qEEG is typically performed before the start of neurofeedback therapy, or after several months of neurofeedback in the event you are not seeing the results you expect from your neurofeedback sessions. The qEEG gives us information on auditory and visual processing and cortical intensity: how hard does your brain have to work to complete a simple task?

QEEG is intended to gather data for tailoring treatment recommendations and protocols to the needs of the client. Schedule a FREE consultation with one of our clinicians to find out if a qEEG session will help you.

Conditions that can be helped when utilizing data from a qEEG include:

  • Insomnia/sleep concerns
  • Attentional concerns
  • Headaches, migraines
  • Anxiety/OCD
  • Depression
  • Autism spectrum
  • Peak performance
  • Post-concussion syndrome
