A recent Rochester study found some positive results with a new neurofeedback imaging treatment approach.
In recent years, researchers have begun using functional magnetic resonance imaging (fMRI) not just for better understanding 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.
While rtfMRI-NF has emerged in recent years as a promising experimental intervention, it’s also a costly procedure that requires extensive technical setup to allow for real-time analysis. That’s why a quantitative data review was overdue.
Regulating Neural Activity
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. Researchers 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.
The 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 treatment method for psychiatric illness.
Other Rochester staff 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.
More Research is Needed for Neurofeedback Imaging Treatments
Yet, there are caveats: the data show less clear evidence that volitional control over the brain regions targeted by neurofeedback translates to an improvement in a person’s symptoms or cognitive impairments. For example, when analyzing the impact of rtfMRI-NF on symptoms, the team found an approximately 60 percent chance that a randomly selected person who received rtfMRI-NF showed improvement in symptoms compared to a randomly selected person who received a placebo procedure.
Moreover, the analysis of publication bias—that’s the team’s attempt to estimate whether there are other studies that have not been published and which may have failed to find an impact of rtfMRI-NF on symptoms—suggests that the positive effect on symptoms may even be smaller than 60 percent.
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.
Neurofeedback Imaging Treatment Meta-Analysis
For their meta-analysis, researchers 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.
The Future of Neurofeedback Imaging Treatments
Together, the data suggest a positive impact of rtfMRI-NF on 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.
The authors of the study are seeking more people with schizophrenia 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.
