Neurofeedback for obsessive compulsive disorder: A randomized, double-blind trial.

Area of Science:

• Neuroscience
• Psychiatry
• Medical Imaging

Background:

• Obsessive compulsive disorder (OCD) is a debilitating mental health condition.
• Prior research indicated anterior prefrontal cortex (aPFC) activity modulation may help manage OCD symptoms in subclinical populations.
• fMRI neurofeedback offers a potential non-invasive therapeutic avenue for OCD.

Purpose of the Study:

• To evaluate the efficacy of fMRI neurofeedback targeting the aPFC as a treatment for patients with OCD.
• To assess the impact of aPFC neurofeedback on symptom reduction and volitional control over brain activity in OCD patients.

Main Methods:

• A randomized, double-blind, sham-controlled clinical trial (NCT02206945) was conducted.
• Participants with OCD viewed symptom-provoking stimuli and underwent fMRI neurofeedback to regulate aPFC activity.
• The active group received real neurofeedback, while the control group received yoked sham feedback.

Main Results:

• The active neurofeedback group demonstrated a statistically significant reduction in obsessive-compulsive symptoms compared to the control group (p<.05).
• No significant differences were observed in the ability to control aPFC activity between the active and control groups.
• Thirty-six participants completed the study, with 18 in each group.

Conclusions:

• fMRI neurofeedback targeting the aPFC is a viable intervention for reducing OCD symptoms.
• Further research is needed to optimize neurofeedback protocols for enhanced efficacy and to elucidate the underlying mechanisms of action.
