QEEG stands for quantitative electroencephalogram. Standard EEG has been around for almost a century. It’s the same technology a neurologist uses when checking for seizure activity, except a neurologist is reading raw squiggles by eye and looking for spikes that don’t belong. A QEEG takes the same raw recording and runs it through statistical software that compares your brainwave patterns, point by point, to a normative database of thousands of people without your symptoms.

That comparison is the whole game. Your brain produces electrical activity at different frequencies. Delta is slow and dominates deep sleep. Theta shows up during drowsiness, daydreaming, and certain meditative states. Alpha is the relaxed-but-awake band. Beta is fast and shows up during focused, alert thinking. Higher beta and gamma show up during intense concentration or, sometimes, during anxiety.

A healthy brain produces all of these in roughly the right amount, in the right places, at the right times. When the proportions are off (too much slow activity in the front of the brain, too much fast activity in the back), the symptoms you came in with often track that imbalance closely. The QEEG shows the imbalance. The neurofeedback that follows is how we train it.

The recording uses 19 to 21 sensors arranged in a standardized layout called the 10-20 system, which is why your map can be compared to a database. We capture two conditions: eyes open for several minutes, then eyes closed. Total time on the cap is 20 to 30 minutes. The analysis afterward takes longer than the recording.

When the analysis is done, your brain map looks like a series of colored heads viewed from above. Each head represents one frequency band: delta, theta, alpha, beta, high beta. The colors show how your brainwave activity in that band compares to the normative database. Green is roughly typical. Yellow and red are above average. Blue is below average. The same sites appear on every head, so you can see how the imbalance moves across frequencies.

What we’re looking for is patterns, not single hot spots. A common pattern in adult ADHD presentations is excess slow-wave activity (theta) over the front of the brain combined with reduced fast-wave activity in the same region. The interpretation is straightforward: the part of the brain responsible for sustained attention is running too slow, like a car idling when it should be cruising. Training the brain to suppress that excess theta and produce more alert beta in the front is one of the better-validated neurofeedback protocols in the literature.

Anxiety and trauma often show a different signature. Excess high beta across the cortex. Reduced alpha. Coherence patterns that suggest the brain isn’t shifting between states efficiently. People with these maps frequently describe themselves as wired and tired, unable to settle even when they’re exhausted. Their brains are stuck in the alarm band.

Depression often shows asymmetry between the frontal lobes, with the left side underactive relative to the right. PTSD frequently shows altered default mode network activity, the network the brain runs when it isn’t focused on a task. Mild traumatic brain injury (TBI) often shows excess slow waves in the area of impact, even years after the event, even when MRI and CT have come back clean. The QEEG sees electrical activity that structural imaging can’t.

None of this means a QEEG diagnoses these conditions. It doesn’t. A diagnosis is a clinical decision made by a qualified provider using the full picture: your history, your symptoms, validated assessments, and rule-outs. The QEEG is one piece of data, and the part of the picture it shows clearly is the electrical baseline, which is exactly the part neurofeedback can train.

You can find clinics in Houston that will start neurofeedback without a brain map. They use what’s called a symptom-based protocol. The client says they have anxiety, the clinic runs an anxiety protocol. The client says ADHD, they run an ADHD protocol. The advantage is that it’s faster and cheaper to start. The disadvantage is that brains aren’t standardized.

Two clients with the same diagnosis can have very different QEEG signatures. Anxiety driven by excess high beta is trained one way. Anxiety paired with reduced alpha and frontal asymmetry is trained another. Anxiety on top of a TBI signature is trained a third way. The diagnosis tells us what the symptoms feel like. The QEEG tells us what the brain is actually doing. Without the map, we’d be guessing which protocol fits, and the wrong protocol can either do nothing or, in some cases, make symptoms worse before getting better.

We treat the QEEG as the standard of care, not an upsell. Our Clinical Director is board-certified in neurofeedback (BCN) through the Biofeedback Certification International Alliance, and BCN-level practice does not involve guessing. The credential exists precisely so the field has a defined standard for QEEG-informed protocol design.

A QEEG is required before any neurofeedback at our practice. If you have a recent QEEG from another qualified provider (within the last 12 months, run on standard equipment with a 19-channel layout), we’ll often accept it rather than repeat one. If you don’t, we’ll do the map first, talk through the findings together, and design the protocol from there. There is no scenario in which we run training on a brain we haven’t measured.

Board Certification in Neurofeedback (BCN) is a credential issued by the Biofeedback Certification International Alliance. It requires graduate-level mental health licensure, didactic training in neuroanatomy and brainwave assessment, supervised clinical hours, and a written exam. It is the credential the neurofeedback field treats as the bar for independent practice. Plenty of people use neurofeedback equipment without it. The credential tells you which providers have demonstrated they know how to read what they’re looking at.

QEEG interpretation is where this matters most. A QEEG report from a database isn’t a verdict. It’s a probabilistic comparison, and reading it well requires knowing how to handle artifacts (eye blinks, muscle tension, drowsiness all show up in the data and have to be cleaned out before interpretation), how to weigh competing patterns, and how to tell the difference between a finding that’s clinically meaningful and a statistical quirk that means nothing. None of that is automated. The software flags. The clinician interprets.

Our Clinical Director, Guy Bender, LPC, holds the BCN credential and oversees QEEG interpretation and protocol design at the practice. The team page has more on his training and the rest of the clinical staff. You can read more about the clinicians who’ll be involved in your map review and your training plan.

We’re a private-pay practice, and we don’t bill insurance for the QEEG. For current pricing on the QEEG itself and for neurofeedback session blocks, the cleanest place to see specifics is our costs page. The two posts on neurofeedback pricing also break it down: our current neurofeedback cost guide for Houston and the older deep dive on what neurofeedback costs in Houston. Both walk through the math.

What’s bundled with a QEEG at our practice: the recording session, the data cleaning and analysis, the brain map report, and the brain map review session where we walk you through it. You don’t get charged separately for any of those steps. The QEEG is a one-time charge, not a per-visit fee, and the report is yours to keep.

If you have a PPO insurance plan, some clients receive partial out-of-network reimbursement after submitting a superbill. We can’t guarantee what your specific plan will cover, but we can provide the documentation. Many of the clients who do this end up with meaningful reimbursement because the QEEG and the neurofeedback that follows have CPT codes their insurer recognizes, even when we don’t bill directly.

If cost is a constraint, the honest conversation is the one to have. Some clients spread the QEEG and the first block of training over two months. Some come twice a week for a focused block and then drop to maintenance. We’d rather build a plan that fits your budget than have you stall out.
