Brain Imaging Can Predict How Well Psychotherapy May Work for Depression

New research shows that brain scans can predict which patients with clinical depression are most likely to benefit from a specific kind of talk therapy.

University of North Carolina (UNC) School of Medicine researchers believe that brain scans could ultimately be used as a diagnostic tool to help patients receive the best treatment as quickly as possible.

The study, published in the journal Neuropsychopharmacology, is the first to use a technique known as resting-state functional brain connectivity MRI. The technology allows scientists to identify differences in brain wiring that predict therapeutic responses to talk therapy.

“In the future, we will be able to use non-invasive brain imaging technology to match patients with the treatment option that has the best chance of lifting their depression,” said senior author Gabriel S. Dichter, Ph.D., associate professor of psychiatry and psychology.

“In my mind, that’s as important as developing new treatments. We already have a lot of excellent treatments but no way to know which one is best for a particular patient.”

Dichter added that if doctors can identify the best treatment immediately, then doctors and patients could avoid months of trial and error, thus dramatically reducing the often debilitating effects of depression for patients and their families.

Major depressive disorder, also known as clinical depression, is the second leading cause of disability worldwide. Approximately one in six people will experience at least one bout of depression, and many will suffer multiple bouts over the course of their lives.

Although a variety of treatment options are available, clinicians must often resort to trial and error to determine the most effective course of care.

Currently, experts estimated that 40 percent of people are not helped by the first treatment — be it antidepressant medications, different kinds of talk therapies, or brain stimulation. As a result, it can take patients multiple attempts with different treatments before symptoms ease.

Dichter and longtime collaborator and co-senior author Moria J. Smoski, Ph.D., assistant professor of psychiatry and behavioral sciences at Duke University, have spent the last decade using brain imaging technology to understand how depression changes the brain.

Recently, the researchers shifted their focus to explore ways to treat patients more effectively. They began studying whether brain scans could predict which patients would respond to a specific kind of talk therapy, an effective treatment that has been shown to change the patterns of brain activity in patients.

The researchers recruited 23 patients with major depressive disorder who were not yet being treated. The patients underwent a specific type of brain scan known as resting-state functional connectivity MRI, or rs-fcMRI, which visualizes the coordinated activity of various brain regions within known functional networks of neurons while the brain is not engaged in any particular tasks.

By using this technique, the researchers could identify brain regions that light up or activate in unison. This, in turn, could help them uncover networks of activity that might be linked to certain behaviors or responses to therapy.

After the patients were scanned, they met with counselors for an average of 12 weekly talk therapy sessions using a method known as behavioral activation talk therapy.

Whereas other forms of talk therapy might involve analyzing childhood experiences or altering thought processes, behavioral activation talk therapy focuses on the immediate behaviors associated with depression, such as difficulty getting to work on time or not spending time with loved ones. During the talk therapy sessions, patients set goals to address these behaviors.

Andrew Crowther, a UNC graduate student in neurobiology and first author of the Neuropsychopharmacology paper, then analyzed the data to spot relationships between brain connectivity and responses to treatment. He found two connectivity patterns that stood out among patients who benefited most from talk therapy.

First, these patients had greater connectivity between the anterior insular cortex, a prune-sized region involved in assigning importance to events, and the middle temporal gyrus, a flattened section of brain tissue that plays a role in the subjective experience of emotion.

Second, patients had stronger connections between the intraparietal sulcus, a snake-like structure involved in maintaining focus, and the orbital frontal cortex, a crescent-shaped brain region behind the eyes involved in assigning positive or negative values to events.

“There’s a complex interplay between the regions of the brain that are involved in cognitive control and those regions involved in understanding how something is going to feel,” said Dichter.

“We’ve known for a long time that atypical connections between those regions are involved in depression, but now we know that they can also be involved in how a person responds to talk therapy.”

Dichter and his colleagues plan to extend their imaging studies to explore responsiveness to other forms of talk therapy, antidepressant medications, and brain stimulation.

“It’s a long road to find the right treatment for each patient,” Dichter said.

“Our goal is to develop a road map, to use this type of information to predict which patients will respond to which treatments.”
