Neurofeedback — Frequently Asked Questions
About Neurofeedback
What exactly is neurofeedback?
Neurofeedback (also called EEG biofeedback or neurotherapy) is a non-invasive brain training technique that measures your brainwave activity in real time and provides immediate feedback — usually through sound or visuals — that helps guide your brain toward healthier, more regulated patterns. Over a course of sessions, the brain learns to sustain those patterns on its own. No medication, no electrical stimulation — only measurement and feedback.

How is neurofeedback different from regular therapy?
Talk therapy works primarily through the cortex — language, insight, conscious processing. Neurofeedback works at the level of brainwave regulation, which sits below conscious awareness. Many conditions — ADHD, PTSD, anxiety, sleep disorders — have a neurological component that talk therapy alone does not address. Neurofeedback targets that component directly, and can be used alongside psychotherapy for a more comprehensive approach.
Is neurofeedback safe?
Yes. Neurofeedback has been used clinically for over 50 years and has a strong safety record. No electricity is delivered to the brain — only brainwave activity is measured. The most common side effects reported are temporary fatigue or mild headache after sessions, which typically resolves within hours. Neurofeedback is considered safe for most ages and health conditions.
What does a neurofeedback session feel like?
Sessions are generally relaxing. Sensors are placed on your scalp (no needles, no discomfort), and you sit comfortably watching a screen or listening to audio that responds to your brainwaves in real time. Many people find sessions calming — some fall asleep. Sessions are 45–60 minutes and include time for both brain training and check-in with Dr. Samuel.
What Neurofeedback Treats
Does neurofeedback work for ADHD?
ADHD is the most researched application of neurofeedback, with over 40 randomized controlled trials. The evidence shows significant improvements in attention, impulsivity, and hyperactivity — with some meta-analyses showing effect sizes comparable to stimulant medication. Neurofeedback targets the excess theta (slow-wave) activity that is a neurological hallmark of ADHD, training the brain to sustain the faster, more focused activity associated with concentration. See: Neurofeedback Research Evidence.
Can neurofeedback help with anxiety?
Yes. Anxiety often involves excess high-frequency beta activity — the brain running “too hot.” Neurofeedback protocols can train the brain to reduce this excess activation, lowering the baseline arousal that drives anxiety, worry, and panic. Alpha training (increasing calm, present-focused brainwaves) is also commonly used for anxiety. Published studies report improvements in both the frequency and intensity of anxiety symptoms after 10–20 sessions.
Does neurofeedback help with trauma and PTSD?
Yes. Trauma dysregulates the autonomic nervous system and alters brainwave patterns — particularly in the prefrontal cortex (responsible for emotional regulation) and the limbic system (responsible for threat detection). Neurofeedback helps stabilize these patterns, reducing hypervigilance, emotional reactivity, sleep disturbance, and the physiological activation associated with trauma. Dr. Samuel often uses neurofeedback as a stabilization tool before beginning EMDR or other trauma processing. See: Trauma Therapist Vancouver.
Can neurofeedback help with sleep problems?
Yes. Neurofeedback has a solid evidence base for insomnia and sleep dysregulation, particularly when these are rooted in nervous system hyperarousal (as in anxiety, PTSD, or trauma). Protocols targeting delta and sigma (sleep spindle) brainwaves can improve both sleep onset and sleep quality. Neurofeedback may be particularly helpful for trauma-related insomnia when combined with trauma therapy.
Can neurofeedback replace medication for ADHD or anxiety?
For some clients, yes — neurofeedback has helped people reduce or eliminate psychiatric medication under physician supervision. For others, it works best as an adjunct that enhances the effectiveness of medication. Dr. Samuel does not advise clients to stop medication without consulting their prescribing physician, but he works collaboratively with clients and their medical team when medication changes are being considered.
Practicalities
How many neurofeedback sessions will I need?
Research reports that many people notice changes after 8–12 sessions, and a typical course of neurofeedback runs 20–40 sessions. ADHD and anxiety tend to respond in the lower range; complex trauma, sleep disorders, and more entrenched patterns may require more. Dr. Samuel tracks your progress throughout and adjusts the protocol as your brain responds. A QEEG brain map at the beginning provides a baseline to measure against.
What is a QEEG brain map and do I need one?
A QEEG (Quantitative EEG) is a 20–30 minute recording of your brainwave activity across 19 sites, compared to age-matched norms. It identifies specific areas of dysregulation — where the brain is producing too much or too little of a given frequency, and where connectivity between regions is poor. Dr. Samuel uses QEEG to design a targeted protocol for your specific neurological pattern rather than applying a generic approach. QEEG-guided neurofeedback tends to produce faster, more precise results.
How long do the results of neurofeedback last?
Results from neurofeedback training are generally durable. Unlike medication — which works only while you take it — neurofeedback produces lasting changes in how the brain regulates itself. Research follow-up studies show maintained improvement at 6 months and in some cases years after treatment. Some clients return for brief “booster” sessions during periods of high stress.
Is neurofeedback available in Farsi?
Yes. Dr. Samuel is Iranian-Canadian and conducts all sessions — including neurofeedback and QEEG consultations — in both English and Farsi. See: Farsi Therapist Vancouver.
Is neurofeedback covered by insurance?
Coverage depends on your plan. Many extended health plans cover neurofeedback when billed under registered clinical counselling or mental health services. Dr. Samuel’s practice accepts ICBC, FNHA, Sun Life, and Shifa Therapy billing. Contact the clinic to confirm your specific coverage before starting.

Who you’re talking to
I’m Samuel Ezzatilord. Over 25 years I’ve worked with trauma, anxiety, and relationships — from Red Crescent refugee camps and veterans’ clinics to community mental health here in Vancouver. I won’t be shocked by what you bring me, and I won’t rush you.
As an Iranian-Canadian clinician working in both English and Farsi, I understand the weight of آبرو, the pull between cultures, and how hard it can be to say “I need help” out loud. We go at your pace, find what’s really driving things, and work through it together.
And no — your problem doesn’t need to be a crisis to belong here. Most of the people Samuel sees are simply tired, stuck, or quietly carrying something heavy.
