Neurofeedback Training & Psychological Disorders

Neurofeedback Training & Psychological Disorders

Posted on: November 8th, 2022 by Neurohealth Associates

In recent years, researchers have begun using functional magnetic resonance imaging (fMRI) not just for a better understanding of the neural bases of psychiatric illness, but also for experimental treatment of depression, ADHD, anxiety, PTSD, substance use disorder, and schizophrenia with a technique called real-time fMRI neurofeedback.

A team of University of Rochester psychologists set out to determine if rtfMRI-NF can help a person regulate neural activity in a way that might improve psychiatric illness: They looked at 17 relevant studies that included a total of 410 participants. The findings of their meta-analysis have been published in the journal Neuroscience and Biobehavioral Reviews.

According to the lead author, their review found that when people were shown their own brain patterns in real-time, they were able to regulate activity in specific regions of the brain. “This training, known as neurofeedback, offers an exciting and novel treatment method for psychiatric illness.”

Coauthors agreed that the findings are “very promising,” especially because there are very few treatments, psychopharmacological included, that specifically target neural circuits known to contribute to psychopathology.

Analyzing Neurofeedback Training

The team analyzed symptom and cognition data in a variety of ways, and some analyses, especially those that looked at outcomes over a wide spread of mental illnesses—such as anxiety, depression, and psychosis—were more favorable. For example, they found clearer evidence that rtfMRI-NF may improve a person’s responses to aversive situations or contexts, such as fear, anxiety, and loss.

For their meta-analysis, the team evaluated rtfMRI-NF in two contexts: first when participants were regulating their brain’s response while receiving neurofeedback in so-called training sessions, and second when participants were regulating without neurofeedback in so-called transfer sessions to see if the previously learned regulation could be maintained in daily life.

Indeed, patients across a range of mental illnesses were able to use a neurofeedback signal delivered through rtfMRI to self-regulate neural activity in the targeted region. Next, the team examined whether people can truly learn to control certain brain regions and whether they can regulate the targeted regions even when neurofeedback is not available.

The analysis of so-called transfer scans—taken at a follow-up session—found that participants were able to intentionally control targeted brain regions even in the absence of a neurofeedback signal. The data indicated that while rtfMRI-NF has a moderate impact on targeted regions during training, that impact increases later when the neurofeedback signal is not provided.

Controlling the Brain

The author believes this provides relatively strong evidence that volitional control over neural processes that are specifically targeted during training is possible. Together, the data suggest a positive impact of rtfMRI-NF on the brain and behavioral outcomes, although more research is needed to determine how exactly it works, under what circumstances, and for whom specifically, says Dodell-Feder.

Future studies from the same team are looking at people with schizophrenia to use neurofeedback training to self-regulate regions of the brain that are important for social information processing. The study is ongoing and early results, while still limited in number, look promising.

Neuro Fact

A 20-year-old man has around 109,000 miles (176,000 km) of myelinated axons in his brain, which is enough to wrap around the earth’s equator four-and-a-half times

What Clients Say About Us


Julie W.
Teachers made huge comments on his math skills and behavior. I also saw this at home with understanding of what I said to him registering more with him. I saw this in his eyes: recognition. Fewer outbursts of anger.

Anita M.
I am extremely happy with my son’s outcomes and feel very fortunate to have encountered Dr. Bonesteel early in my child’s life. This method has dramatically changed his ability to focus and take initiative. I feel confident that my son’s life has been dramatically enhanced. I can’t express my appreciation fully in words.

Mary B.
Dr. Bonesteel has masterfully, compassionately, and extremely kindly helped me navigate through a history of childhood and marital abuse, a child with twenty years of struggle with life-threatening physical and emotional illness, extended family discord, and disharmony with my child with severe depression. I am blessed to have found Neurohealth Associates.
