If you are exploring care at our clinic, it is completely normal to feel unsure about what happens during a qEEG. Many people arrive with questions, concerns, or even a little nervousness. Understanding what happens during a qEEG can help reduce uncertainty and make the experience feel more approachable. Our goal is to guide you through each step with clarity, compassion, and respect for your comfort.
A qEEG, also called quantitative electroencephalography, is a way to measure and understand patterns of brain activity. At The Insync Brain, every patient receives a qEEG before starting care. This includes individuals pursuing standard TMS for treatment-resistant depression, as well as those considering MeRT®. Taking the time to look closely at your unique brain activity helps us make thoughtful, informed recommendations and helps you better understand what may be happening beneath the surface.
What a qEEG Measures
A qEEG measures electrical activity in the brain. These electrical signals are something your brain produces naturally as neurons communicate with one another. The test does not put anything into your body and does not stimulate the brain. It simply records activity that is already there.
The information collected during a qEEG allows clinicians to see how different areas of the brain are functioning in relation to one another. It can highlight patterns that may be associated with certain symptoms, such as changes in mood, attention, sleep, or emotional regulation.
In simple terms, a qEEG helps answer questions like:
- Which areas of the brain are more active or less active than expected
- How different regions of the brain are communicating
- Whether brain activity appears balanced or dysregulated
For patients, this can be validating. Many people have struggled for years without understanding why certain symptoms persist. Seeing brain activity data can provide insight and help explain experiences that may have felt confusing or frustrating.
Why Every Patient Receives a qEEG at Our Clinic
At our clinic, a qEEG is part of the foundation of care. Even patients who are pursuing standard TMS for treatment-resistant depression receive a qEEG before beginning treatment.
For individuals doing standard TMS, the qEEG helps guide the clinician’s treatment recommendations. While standard TMS uses a 10 Hz protocol that works very well for many people, the qEEG offers additional information about brain activity that can support clinical decision-making and patient education.
For patients considering MeRT®, the qEEG plays an even larger role. MeRT® protocols are guided directly by qEEG findings. Two key elements of the protocol may change based on the qEEG:
- Location, meaning where stimulation is delivered
- Frequency, meaning how fast the stimulation is delivered
Unlike standard TMS, which uses a one-size-fits-all frequency, MeRT® is designed to adapt to the brain’s specific patterns. This is one reason MeRT® can be used across a wider range of conditions. At our clinic, TMS can be used only for treatment-resistant depression, while MeRT® is used for other conditions based on individualized brain data.
What to Expect During Your qEEG Appointment
The qEEG appointment typically takes about 30 to 40 minutes from start to finish. The process is calm, quiet, and guided by a trained neurotechnician who will be with you the entire time.
Preparation
Before recording begins, the technician will walk you through the setup process. This includes:
- Gently cleaning specific areas such as the forehead, ears, and a spot below your collarbone
- Measuring for and placing a soft cap on your head, which is used to collect the data
- Applying a small amount of gel to help the cap electrodes collect clear data
- Checking signal quality to ensure accurate recording
The technician takes time to make sure everything looks right before moving forward. This step is important for collecting clean, reliable data.
The Recording
Once preparation is complete, the actual recording begins. The recording itself lasts about 10 minutes and is done with your eyes closed.
During this time, the technician may remind you to:
- Keep your brain active rather than entering a meditative state
- Stay relaxed but alert
- Keep facial muscles as relaxed as possible to reduce muscle activity in the data
You are not expected to perform tasks or answer questions during the recording. You simply sit comfortably and follow gentle guidance from the technician.
Throughout the appointment, you are encouraged to ask questions. The technician is there to support you and help you feel at ease.
The Consultation: Reviewing Your History and Results
After your qEEG, you will meet with one of our clinicians for a thorough consultation. This is a thoughtful, collaborative conversation rather than a rushed appointment.
During the consultation, the clinician will:
- Review your full medical and mental health history
- Discuss your current symptoms and goals
- Go over your qEEG findings in clear, understandable terms
- Explain how the results relate to your experiences
- Discuss potential treatment options
If the clinician believes that TMS or MeRT® may be appropriate, they will explain why and answer any questions you have. If another approach may be a better fit, that will be discussed as well. Our priority is education and informed decision making, not pushing a specific treatment.
How qEEG Results Are Used to Guide Care
One of the most meaningful parts of the qEEG process is how the information is used. The data does not stand alone. It is considered alongside your history, symptoms, and goals.
For patients pursuing standard TMS for treatment-resistant depression, qEEG findings help inform clinical recommendations and provide insight into brain changes over time.
For patients pursuing MeRT®, the qEEG directly guides the treatment protocol. Adjustments in location and frequency are based on your unique brain activity, allowing care to be tailored to your needs rather than relying on a fixed approach.
Many patients find it empowering to see their results and understand how care is being guided by objective data.
A Compassionate and Educational Approach
We understand that starting care can feel overwhelming. That is why we take the time to look closely at your brain before beginning treatment. Our commitment to compassion and education means you are never expected to move forward without understanding your options.
A warm, supportive environment and clear communication are central to our approach. The qEEG and consultation are not just about gathering information. They are about building trust, answering questions, and helping you feel confident in the path ahead.
If you are considering care and wondering whether this approach might be right for you, learning what happens during a qEEG is often the first step toward feeling more comfortable and informed.
