neurofeedback
“I’ve been doing neurofeedback for over a decade. It’s a great way for my brain to be at its absolute best.
The beautiful thing is you just watch the video and the training happens [without effort].”
How it works: just stream…
Can brain training be as simple as watching TV?
Neurofeedback training takes advantage of neuroplasticity, the ability of the brain to re-wire as a result of experience. Neurofeedback is a lot like learning to ride a bike. You get immediate “feedback” when you’re off-balance on your bike. Soon you learn how to balance without reading or memorizing anything. During a neurofeedback session your brain gets video feedback signals when brain activity shifts toward training goals (for example, better attention or less anxiety).
How does this happen? It uses sensors placed on your scalp to monitor your brain's activity, i.e. brainwaves. Brainwaves reflect information flow and your state of mind (for example anxious, focused, or ruminating). A computer interprets what brain areas are active and how well these areas are working together. Neurofeedback software uses this understanding to notify you with a signal when your networks are functioning better. Usually, this is the change of a screen size seen while streaming a favorite show. Without conscious thought or effort, this teaches the brain to shift into improved functioning (AKA functional connectivity). The brain is changing; the networks are becoming stronger.
For example, if you want to relax more or focus better, improving the related brain networks is the most robust way to help. The feedback trains only the weak links in the brain networks to be stronger without “efforting”.
Durable changes:
Research and our years of patient follow up show that neurofeedback training creates permanent changes because training changes physical connections in brain networks. Because each part of the related networks can communicate effectively, they stabilize and can self-regulate. Many patients have returned years after training to testify to the continued benefits they and their loved ones notice. In fact, the best research demonstrates continued improvement over the first 2 years after training (indicating the brain network continues to stabilize and improve self-regulation over time).

Why Precision Neurofeedback?
Neurofeedback has gone through several generations of development. Each step has added more personalization and precision. Here’s how the main approaches differ:
Protocol-Based Neurofeedback (Surface Training Without Assessment)
This early method is still widely used. Clinicians choose from standardized “recipes” without mapping a person’s brain. It’s simple but not personalized.
qEEG-Guided Neurofeedback (Surface Training With Brain Mapping)
Here, general targets are chosen from a quantitative EEG (qEEG) brain map . It’s a more tailored than protocols, but still focused only on the surface and provider assumptions.
Z-Score swLORETA Neurofeedback (Precision Neurofeedback)
This approach combines two breakthroughs:
swLORETA source imaging, which estimates deep and surface brain activity, and
Z-score analysis, which compares that activity to a database of thousands of healthy brains in real time.
The result is whole-network training, helping circuits come back into synchrony — like tuning every section of an orchestra, not just a few instruments.
ICA-Guided swLORETA Neurofeedback (Precision Neurofeedback, Component-Targeted)
Another innovative form of precision neurofeedback applies independent component analysis (ICA) to swLORETA data. This isolates a “pathogenic component” — often linked to a deep brain generator — and allows highly focused training using just 2–3 electrodes.
The evidence
Precision Neurofeedback is proving superior to Gold-Standard Treatments
AUTISM SPECTRUM:
ZL-NFB resulted in significantly increased verbal output, reduced emotional outbursts, greater task independence, and more regulated use of screen-based entertainment. (KZlatkova, 2025, & RAbbey, 2023)
ADHD/Executive Function:
LORETA-NFB (a less advanced form of ZL-NFB) was significantly superior to the standard neurofeedback approach. Specifically L-NFB led to superior improvements in sustained attention, working memory, response inhibition, and cognitive flexibility. (FSamadi, 2025)
In another ADHD, L-NFB treatment led to significant improvements in working memory and improved measures of brain function in ADHD patients compared to fake (aka “sham”) NFB. (ARoberts, 2015)
Depression and Anxiety:
People with Anxious Major Depression had significantly greater relief of their depressive and anxiety symptoms with ZL-NFB than patients who received standard depression and anxiety treatment. (YWu, 2024)
Comparing ZL-NFB to CBT for Depression and Anxiety, neurofeedback proved significantly better. (AFaridi, 2024)
Concussion Treatment:
Z-Scored swLORETA Neurofeedback is superior to conventional neurofeedback and significantly improves attention, executive function, and memory (PChen et al. 2023, & EThomas, 2024)
Substance Use Recovery:
ZL-NFB superior to methadone maintenance and cognitive rehabilitation in reducing cravings, improving quality-of-life and impulse control for patients in rehab for opiod dependence. (AFaridi, 2022 & AFaridi, 2024)
Another study showed ZL-NFB was superior to the gold-standard approach for patients in rehab for opiod dependence in relieving their depression and anxiety symptoms. (AFaridi, 2024)
Eating Disorders:
ZL-NFB significantly helped Body Dysmorphic Disorder (BDD), general eating disorder symptoms, and depressive symptoms in a BDD patient compared to their baseline. (RLouison, 2024)
PTSD:
ZL-NFB very significantly improved PTSD symptoms and general anxiety symptoms in 15 sessions from baseline. The group also demonstrated significant improvements in brain network functioning. (ABell, et al., 2019)
stroke recovery:
In patients who developed the inability to speak after stroke, ZL-NFB improved language, attention and working memory. (FFaridi, et al., 2023)

“I am so happy with the results from my child's neurofeedback treatment. There is a marked difference in her executive functioning, anxiety & stress levels. She is able to deal with hurdles that come up without the hand-holding and guidance she once needed. She is willing to take on new experiences and challenges without her anxiety rising to paralyzing levels. She also has a better understanding of how her brain works and can identify when a situation may trigger her anxiety and how she can deal with it.”

“Dr. Engwall was instrumental in identifying the underlying neurological aspects of our son’s distress. With the proper treatment and our commitment to having our son participate in the neurofeedback, he is now stable, calm, and even happy.”
— Anon
(This patient went from struggling with attention, low motivation and poor self-organization in high school to earning “Straight A’s” in his college honors program.)
“My experience with Dr. Engwall was nothing short of exceptional. He explained the process clearly and in terms that were easy to understand and the EEG techs were super friendly and professional during my sessions. Once my therapy was complete, Dr. Engwall explained my results in terms that were easy to understand and made recommendations of how to adjust my lifestyle to continue to receive maximum benefit.”

“Dr Engwall is the world’s most hidden gem. We were looking for someone with his expertise for a long time and glad we kept looking. He’s helped our daughter re-gain functioning lost after neurosurgery which changed her personality and left her with poor working memory. Dr Engwall’s expertise and collaboration with colleagues at Harvard’s Berenson-Allen Center were key. She now has 99th percentile working memory and neurofeedback has helped her attention and social interactions improve dramatically.”

We’ve been working with Dr. Engwall for the past two years. His genetic testing caught our son’s vulnerability to rapid cycling bipolar disorder, something that can be brought on by the use of SSRI medication. When we first met with Dr. Engwall we had just started our son on Prozac through another psychiatrist. Dr. Engwall was able to catch the warning signs early and based on his genetic testing he recommended we try an alternate medication that has worked extremely well. We also went through 3 rounds of neurofeedback, which helped our son’s executive functioning issues. Dr. Engwall is a thoughtful, caring psychiatrist. … We highly recommend Dr. Engwall, especially if your child has treatment resistant troubles. He has been a lifesaver, literally.

“I believe Dr. Engwall is one of the early adopters of this particular course of treatment. Based on my experience, this treatment seems to be something that will become increasingly mainstream in the next few years. I came in neutral and walked away absolutely convinced. I no longer need meds and my chronic depression and insomnia much improved.”
