Neurofeedback for Treatment Resistant Depression

Status Recruiting

Clinical Trial Summary

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

Clinical Trial Description

Up to two-thirds of patients diagnosed with major depressive disorder (MDD) will not respond to standard pharmacological and psychological interventions and will be considered treatment resistant (TR-MDD). Decreased reactivity to positive stimuli, indexed by low amygdala reactivity to positive autobiographical memory recall, may be a causal mechanism interfering with recovery from TR-MDD. Previous work in our lab suggests that individuals who do respond to antidepressant medications show increased amygdala activity that is indistinguishable from controls relative to baseline, while TR-MDD individuals fail to show this increase in amygdala activity. Furthermore, the investigators have found that MDD participants (more generally, not specifically TR- MDD) are indeed able to increase their amygdala response during positive memory recall via real-time fMRI neurofeedback (rtfMRI-nf) training, and that this increase is associated with large and rapid reductions in depressive symptoms. Here, the investigators propose to evaluate whether rtfMRI-nf training to increase the amygdala response to positive memories may serve as an intervention for TR-MDD. 100 TR-MDD individuals will be randomly assigned under double-blind conditions to receive 5 amygdala rtfMRI-nf or 5 control rtfMRI-nf sessions where they are trained to regulate a parietal region putatively not involved in emotional processing or MDD. The investigators will assess changes in amygdala activity, severity of clinical symptoms, and autobiographical memory deficits. Success will suggest a new non- pharmacological, non-invasive intervention for a traditionally treatment-resistant population of MDD individuals. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
