Trial Summary

Will I have to stop taking my current medications?

You can continue taking your current SSRI antidepressant if it's stable for at least 3 weeks. However, you must stop taking any antipsychotics, anticonvulsants, stimulants, benzodiazepines, beta-blockers, or other medications that might affect brain blood flow at least 3 weeks before the trial.

What data supports the effectiveness of the treatment Amygdala Neurofeedback for Depression?

Research shows that Amygdala Neurofeedback, which involves training the brain to respond more positively using real-time brain imaging, can help reduce symptoms of depression. Studies found that this treatment can improve emotional processing and increase brain connectivity, leading to better mood regulation in people with depression. ^{1 2 3 4 5}

Is Amygdala Neurofeedback safe for humans?

Research on real-time functional MRI neurofeedback (rtfMRI-NF) involving the amygdala has been conducted with healthy participants and those with a history of depression, showing that it can help regulate brain activity without reported safety issues. These studies suggest that the technique is generally safe for human use. ^{1 3 6 7 8}

How is Amygdala Neurofeedback treatment different from other treatments for depression?

Amygdala Neurofeedback is unique because it uses real-time brain imaging to help individuals learn to control their brain activity, specifically targeting the amygdala, which is involved in emotional processing. This approach is different from traditional treatments like medication or talk therapy, as it directly trains the brain to improve emotional regulation and processing of positive information. ^{1 2 3 9 10}

What is the purpose of this trial?

The purpose of this study is to determine the clinical efficacy of real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) training to increase the amygdala's response to positive autobiographical memories in patients with depression who are considered treatment-resistant

Treatment Details

Interventions

• Amygdala Neurofeedback
• Parietal Neurofeedback

Trial Overview The study tests if neurofeedback using real-time fMRI can help patients with treatment-resistant depression by enhancing the amygdala's response to positive memories. It involves two types of neurofeedback: one targeting the parietal region and another focusing on the amygdala of the brain.

Participant Groups

Group I: Amygdala Neurofeedback Experimental Treatment 1 Intervention

attempt to up regulate the left amygdala during positive autobiographical memory recall via real time fMRI neurofeedback from the amygdala. Five sessions will be performed within a 2 month period.

Group II: Parietal Neurofeedback Active Control 1 Intervention

attempt to upregulate the left horizontal segment of the intraparietal sulcus, a region not involved in emotional processing, during positive autobiographical memory recall via real time fMRI neurofeedback. Five sessions will be performed within a 2 month period.

Findings from Research

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.

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.

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.

Real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) training targeting the left amygdala can reverse abnormal brain connectivity in individuals with major depressive disorder (MDD), leading to significant improvements in mood and depression severity.

The study found that the positive effects of rtfMRI-nf training are associated with increased connectivity between the amygdala and other brain regions, such as the hippocampus, suggesting that this approach may help rehabilitate emotion regulation in depressed individuals.

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.

In a study involving 48 healthy female participants, real-time functional MRI neurofeedback (rt-fMRI-NF) training showed that providing feedback on amygdala activation during exposure to aversive scenes can help improve the down-regulation of amygdala activity.

Participants who received amygdala feedback demonstrated a significant ability to down-regulate amygdala activation in a subsequent test without feedback, suggesting that this neurofeedback training may be beneficial for individuals with emotion dysregulation.

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.

Real-time functional MRI neurofeedback (rtfMRI-nf) training has shown promise in helping individuals, both healthy and those with depression, to regulate brain activity in the amygdala, which may enhance positive memory recall.

While initial studies indicate that rtfMRI-nf could help alleviate symptoms of major depressive disorder, further research with larger participant groups is needed to confirm its effectiveness as a clinical intervention.

Real-time functional magnetic resonance imaging-based neurofeedback (rt-fMRI NF) is a promising technique for treating depression by training individuals to self-regulate brain areas like the amygdala, which is often overactive in response to negative stimuli.

Initial randomized controlled trials show promising results for rt-fMRI NF in improving emotional processing, but further research is needed to determine the best methods, target regions, and training durations for lasting clinical benefits.
