The short answer
A quantitative electroencephalogram (qEEG) is a non-invasive, computerized analysis of your brain's electrical activity. A soft cap with 19 sensors records your brainwaves; software then compares those patterns to a database of healthy brains to identify regions that are over- or under-active, or poorly connected.
How qEEG works
- Cap placement. A sensor cap is placed on your scalp. No needles, no discomfort.
- Recording. 5–10 minutes with eyes open, 5–10 minutes with eyes closed.
- Statistical comparison. Your data is compared to a normative database to flag areas outside the expected range.
- Clinical interpretation. A trained physician translates the map into a treatment plan — including whether TMS therapy can help and where to target it.
What qEEG measures
- Power. How strong each brainwave frequency (delta, theta, alpha, beta, gamma) is in each region.
- Coherence. How well different brain regions communicate with each other.
- Symmetry. Whether left and right hemispheres are balanced.
- Phase. Timing of neural communication across regions.
Conditions qEEG can help guide treatment for
- Autism Spectrum — qEEG Autism & Autism Brain Mapping
- ADHD and attention challenges
- Anxiety and panic
- Depression (especially treatment-resistant)
- PTSD and trauma-related symptoms
- Traumatic Brain Injury and concussion recovery
- Emotional regulation challenges
- Sleep disorders
Frequently asked questions
What is qEEG brain mapping?
qEEG (quantitative electroencephalogram) is a non-invasive recording of your brain's electrical activity using a sensor cap. The data is statistically compared to a normative database to identify regions of dysregulation linked to mental-health, attention, and developmental symptoms.
Is qEEG safe? Does it hurt?
qEEG is painless, non-invasive, and uses no radiation. It only records — it does not emit anything into the brain. It is safe for children and adults.
How is qEEG different from a traditional EEG?
A clinical EEG screens for seizures or gross abnormalities. qEEG goes further: it quantifies your brain's frequency patterns and connectivity, then compares them to a healthy database to guide personalized treatment.
How long does a qEEG take?
About 60–90 minutes total: cap fitting, 5–10 minutes of recording with eyes open, 5–10 minutes with eyes closed, and a walk-through of preliminary findings.
What conditions can qEEG inform?
qEEG can guide care for Autism, ADHD, Anxiety, Depression, PTSD, TBI/concussion, emotional regulation challenges, and sleep disorders.
