Brain training to help stop compulsive behaviors
Neural Mechanisms of Response Inhibition Training for Obsessive-Compulsive Disorder and Related Conditions
This project tests a computerized brain-training program for adults with OCD, hair-pulling, or skin-picking to help them better stop unwanted urges.

What this research studies
You would be asked to complete a computerized response inhibition training (RIT) or a placebo training while researchers measure your brain activity before and after the training. Adults with obsessive-compulsive disorder, trichotillomania (hair-pulling), or skin-picking disorder are randomly assigned to RIT or a control condition. The team uses a go/no-go task and MRI to see whether RIT increases activation in a brain area called the right inferior frontal cortex (rIFC) that helps stop automatic behaviors. The first phase (R61) tests whether the training changes that brain signal in 48 participants, and later phases will test whether those brain changes link to symptom improvements.
Who could benefit from this research
Good fit: Adults diagnosed with OCD, trichotillomania (hair-pulling), or skin-picking disorder who can attend in-person visits and complete computerized tasks and MRI scans are ideal candidates.
Not a fit: People who are unable or unwilling to undergo MRI scanning, who are under 21, or whose primary problems are not compulsive action tendencies may not benefit from this specific training.
Why it matters
Potential benefit: If successful, this could become a non-drug, brain-based training that reduces compulsive urges by strengthening the brain systems that stop unwanted actions.
How similar studies have performed: Related cognitive training and go/no-go approaches have shown mixed early results, and this specific response inhibition training is relatively new and being directly tested for its brain and symptom effects.
