What is the purpose of this trial?

This trial tests a new approach to assist individuals with major depressive disorder using brain feedback technology. Participants engage in sessions designed to boost positive emotions by focusing on happy memories while receiving real-time feedback on their brain activity. The trial includes two groups: one receiving real feedback (Amygdala real-time fMRI neurofeedback) and the other viewing feedback from another participant for comparison. Suitable candidates for this trial have major depressive disorder, are currently experiencing depression, and either aren't on medication or are stable on an antidepressant. As an unphased trial, this study offers a unique opportunity to explore innovative treatment options for depression.

Will I have to stop taking my current medications?

If you are stable on an antidepressant, you can continue taking it during the study. However, if you are taking antipsychotics, anticonvulsants, stimulants, benzodiazepines, beta-blockers, or other medications that might affect brain blood flow, you may need to stop them at least 3 weeks before participating.

What prior data suggests that this neurofeedback technique is safe for treating depression?

Research has shown that real-time brain scans used to provide feedback on the amygdala have been safely tested in both healthy individuals and those with depression. In these studies, participants learned to boost brain activity by recalling positive memories. This approach has, in some cases, reduced symptoms of depression.

The method's safety appears promising. Reviews of several studies have not identified major safety issues or harmful effects from the feedback process itself. Participants generally tolerate it well, suggesting it might be a safe option for those considering joining a trial. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about amygdala real-time fMRI neurofeedback for depression because it offers a unique approach compared to traditional treatments like antidepressants and psychotherapy. Unlike these standard options, this method uses real-time brain imaging to help patients actively regulate their own brain activity, specifically in the amygdala, which is linked to emotions. By empowering individuals to upregulate their amygdala during positive autobiographical memory recall, this technique may provide a more personalized and immediate way to improve mood and emotional well-being. Plus, it offers a non-invasive alternative that doesn't rely on medication, which can be appealing to those who experience side effects from drugs.

What evidence suggests that amygdala real-time fMRI neurofeedback is effective for depression?

This trial will compare two approaches: Amygdala real-time fMRI neurofeedback and Sham feedback. Studies have shown that using real-time brain scans for feedback can aid individuals with depression. This technique enables control over brain activity, particularly in the amygdala, which governs emotions. Research indicates that this method can reduce depressive symptoms by training the brain to respond more effectively to positive memories. Specifically, one study found that depressive symptoms improved for up to 12 weeks after using this feedback technique. Another study confirmed the amygdala's key role in recovering from depression. Overall, early findings suggest that this approach could be a promising treatment for major depressive disorder. ^{1 2 6 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Amygdala real-time fMRI neurofeedback
• Sham feedback

Trial Overview

The study tests if a type of brain scan feedback called rtfMRI-nf can help people by increasing the amygdala's response to positive memories as a treatment for depression. Participants will receive either actual neurofeedback or sham (fake) feedback as part of the study.

How Is the Trial Designed?

Group I: Amygdala real-time fMRI neurofeedback Experimental Treatment 1 Intervention

Amygdala neurofeedback - attempt to upregulate the left amygdala during positive autobiographical memory recall via real time fMRI neurofeedback from the amygdala. Two sessions will be performed one week apart.

Group II: Sham feedback Placebo Group 1 Intervention

Yoked sham - participants will see the amygdala activity of another subject who completed the intervention. Two sessions will be performed one week apart.

Published Research Related to This Trial

Healthy individuals can learn to self-regulate the activity of the amygdala using real-time fMRI neurofeedback, leading to significant increases in blood oxygen level dependent (BOLD) signals during training.

This training not only enhances amygdala activation but also improves functional connectivity within a broader brain network, indicating potential therapeutic applications for neuropsychiatric disorders.

Self-regulation of amygdala activation using real-time FMRI neurofeedback. Zotev, V., Krueger, F., Phillips, R., et al.[2021]

Training patients with major depressive disorder to enhance their amygdalar responses to positive memories using real-time fMRI neurofeedback led to increased amygdalar activity when viewing happy faces and decreased activity for sad faces, indicating a shift in emotional processing.

The training also improved participants' ability to identify positive emotional stimuli and reduced their reaction times to positive faces, suggesting that this neurofeedback approach may have effects similar to those of antidepressant medications.

Real-Time Functional Magnetic Resonance Imaging Amygdala Neurofeedback Changes Positive Information Processing in Major Depressive Disorder. Young, KD., Misaki, M., Harmer, CJ., et al.[2019]

In a study involving 10 individuals with a history of major depressive disorder (MDD) and 12 healthy controls, real-time fMRI neurofeedback (rtfMRI-nf) targeting the connectivity between the amygdala and prefrontal regions showed potential for enhancing emotional regulation, particularly in healthy individuals who exhibited increased frontal cortex activation during training.

Participants with a history of MDD demonstrated a trend towards decreased functional connectivity over the training runs, and while the overall group experienced a reduction in negative emotions, the MDD group specifically showed a significant decrease in positive emotions after the neurofeedback sessions.

The study demonstrated that healthy participants could effectively down-regulate activity in the right amygdala using real-time functional MRI (rtfMRI) neurofeedback while exposed to negative emotional stimuli, suggesting a potential method for emotion regulation.

This approach, which involved four training sessions with six participants, indicates that rtfMRI neurofeedback could be a promising tool for treating emotional disorders by targeting the overactive amygdala, which is often dysregulated in such conditions.

Real-time fMRI neurofeedback (rtfMRI NF) allows individuals to voluntarily down-regulate the amygdala, which is linked to improved connectivity with the ventromedial prefrontal cortex (vmPFC) during emotional processing, as shown in a study with 16 healthy participants.

The study suggests that this increased connectivity may enhance emotion regulation, indicating that rtfMRI NF could be a promising tool for helping patients with severe emotion dysregulation.

Amygdala real-time functional magnetic resonance imaging neurofeedback for major depressive disorder: A review. Young, KD., Zotev, V., Phillips, R., et al.[2020]

In a study involving 35 adults with major depressive disorder, real-time fMRI neurofeedback (rtfMRI-nf) training to enhance amygdala responses during positive memory recall led to significant reductions in depressive symptoms and higher remission rates at 6 months and 1 year follow-up compared to a control group.

The combination of rtfMRI-nf and cognitive behavioral therapy (CBT) encouraged participants to focus more on positive thoughts and behaviors, suggesting that this approach may enhance the effectiveness of standard CBT in treating depression.
