What neurofeedback is (and isn’t)
Neurofeedback is a type of biofeedback that uses real-time information about your brainwave activity to help your brain regulate itself. Sensors are placed on your scalp and measure electrical activity — specifically, the patterns of different brainwave frequencies (delta, theta, alpha, beta, and gamma waves). That information is fed into software that displays it as a visual or auditory signal, usually a game, a video, or a sound.When your brain produces the patterns associated with calm, focus, or stable regulation, the feedback is rewarding — the video plays, the sound continues. When it produces patterns associated with anxiety, disorganization, or hyperarousal, the feedback pauses.Over many sessions, the brain learns to produce the more regulated patterns more consistently. It’s a form of operant conditioning applied to the nervous system.Neurofeedback is not a form of brain stimulation. No electricity goes into your brain. No medication is involved. It is passive monitoring with feedback.What does the evidence say?
The research base is strongest for ADHD. A 2019 meta-analysis published in Neuroscience & Biobehavioral Reviews found neurofeedback to be effective for inattention and hyperactivity in children, with effect sizes comparable to medication in some studies. The American Academy of Pediatrics has classified neurofeedback as a “Level 1: Best Support” intervention for ADHD.For anxiety, the picture is more nuanced. A 2016 review in Applied Psychophysiology and Biofeedback found positive results across studies, but noted that much of the research uses small samples and lacks robust control groups. The honest summary: many people with anxiety report significant benefit, the physiological rationale is sound, but large-scale randomized controlled trials in anxiety are still catching up.For PTSD and trauma, there is growing evidence that neurofeedback addresses the hyperarousal and dissociation that talk therapy alone often can’t reach. Bessel van der Kolk — whose book The Body Keeps the Score is the most widely read trauma text of the past decade — has incorporated neurofeedback into trauma treatment at his clinic for years, and published research supporting its use with PTSD.For sleep disorders, particularly insomnia related to hyperarousal, the theta/alpha training protocols used in neurofeedback have consistent support in the literature.Who tends to benefit
Clinical experience suggests neurofeedback is most useful for people who:- Have anxiety with a strong physical component: racing heart, tension, difficulty breathing, inability to relax even when nothing is actively wrong
- Have tried talk therapy and found it helpful for understanding their anxiety, but still can’t calm their nervous system in the moment
- Are reluctant to use medication, or cannot tolerate medication side effects
- Have ADHD alongside anxiety (a common combination) and are looking for a non-pharmaceutical approach
- Have a trauma history, particularly if they experience hypervigilance, dissociation, or being easily startled
- Have chronic insomnia that doesn’t respond to sleep hygiene changes alone
What to expect in a session
A typical neurofeedback session lasts 30–45 minutes. Sensors are placed on specific points on your scalp using a conductive gel. You sit comfortably in front of a screen. You don’t need to do anything except watch.The first few sessions are often assessment sessions, where the practitioner maps your baseline brainwave patterns across different regions of the scalp. From there, sessions follow a consistent structure. Most people notice something shifting — often a sense of calm or unusual mental clarity — during or after sessions.A full course is typically 20–40 sessions for anxiety or ADHD, depending on the person and the severity. Most practitioners recommend sessions two to three times per week early in the process, tapering off as stability is reached.How neurofeedback fits within a broader treatment approach
Talk therapy addresses the cognitive and relational layer: what happened to you, how you made sense of it, how it shaped your patterns of thinking and relating to others. Approaches like EMDR, CBT, and somatic therapy are the tools here.Neurofeedback addresses the physiological layer: the baseline dysregulation in the nervous system that makes anxiety symptoms hard to turn off even when you intellectually understand what’s happening.For some people, medication is also part of the picture. Neurofeedback is compatible with psychiatric medication and does not interfere with it.Finding neurofeedback in Vancouver
Neurofeedback is offered by a small number of practitioners in Vancouver. When evaluating providers, look for training in a recognized neurofeedback system, a practitioner who also provides or coordinates talk therapy, a clear explanation of what protocols they use based on an initial assessment, and transparent pricing.Dr. Samuel Ezzatilord is a Registered Clinical Counsellor (RCC) in Vancouver offering neurofeedback alongside individual and couples therapy.
