Effects of Amygdala Neurofeedback on Depressive Symptoms

December 2, 2022 updated by: Kymberly Young, University of Pittsburgh
The purpose of this study is to determine the clinical efficacy of augmenting cognitive-behavioral therapy with real-time functional magnetic resonance imaging neurofeedback (rtfMRI-nf) training to increase the amygdala's response to positive autobiographical memories.

Study Overview

Detailed Description

Previous research has shown that real-time fMRI neurofeedback (rtfMRI-nf) training aimed at increasing the amygdala's response to positive autobiographical memory recall holds therapeutic potential for treating patients with major depressive disorder (MDD), as clinically significant decreases in clinician administered and self-report measures of depression severity were observed following two rtfMRI amygdala neurofeedback sessions. Furthermore, rtfMRI amygdala neurofeedback changed emotional processing towards a positive bias. As this rtfMRI-nf procedure utilizes principles of cognitive-behavioral therapy (CBT), including restructuring thoughts and emotional processing towards the positive, the current study seeks to examine the effects of augmenting CBT with amygdala rtfMRI-nf. Specifically, the investigators plan to test the hypothesis that pretreatment with two amygdala rtfMRI-nf sessions prior to the the start of CBT will result in a higher percentage of patients who exhibit 'sudden gains' (a between session drop of at least 25% on the Beck Depression Inventory associated with better treatment response) compared to those who receive rtfMRI-nf from a parietal control region putatively not involved in emotional processing. Over the course of three years, 60 participants diagnosed with MDD and planning to start CBT will be recruited through the clinical services of the Western Psychiatric Institute and Clinic (WPIC) and through licensed CBT therapists in the Pittsburgh metropolitan area. Participants will undergo two rtfMRI-nf sessions within the two weeks prior to starting therapy. Half of the participants will receive amygdala neurofeedback and half will receive control neurofeedback. At weeks 1-3 and 9 & 10 following the start of therapy, the participant will complete the BDI-II and the NIH Patient Reported Outcomes Measurement Information System (PROMIS) Depression measure. The number of patients who meet criteria for sudden gains and the average session at which this occurred will be compared between CBT + amygdala rtfMRI-nf and CBT + control rtfMRI-nf groups. Success will suggest a new method for improving outcomes to CBT in depressed patients.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: real-time fMRI neurofeedback: Amygdala
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.
Participants are shown activity from their left amygdala in real time and are instructed to increase the level of activity in that region by thinking of positive autobiographical memories
Active Comparator: real-time fMRI neurofeedback: HIPS
HIPS neurofeedback - attempt to upregulate the left horizontal segment of the intraparietal sulcus (HIPS), a region not involved in emotional processing, during positive autobiographical memory recall via real time fMRI neurofeedback from the HIPS. Two sessions will be performed one week apart.
Participants are shown activity from their left horizontal segment of the intraparietal sulcus in real time and are instructed to increase the level of activity in that region by thinking of positive autobiographical memories
