Brain circuit differences in OCD and how changing them could help

Neurocircuitry of OCD: Effects of Modulation

['FUNDING_OTHER'] · UNIVERSITY OF ROCHESTER · NIH-11266114

Researchers are using advanced brain scans to compare wiring and activity in people ages 18–35 with OCD to healthy volunteers to understand circuits linked to ongoing avoidance.

What this research studies

If you take part, you would undergo detailed brain scans (diffusion MRI and functional MRI) and behavioral testing while doing a task that involves uncertain unpleasant outcomes. The team plans to compare 50 people with OCD (either unmedicated or on SSRIs/clomipramine) with 50 healthy volunteers aged 18–35 to look at white matter bundles and connectivity among regions like the ventrolateral prefrontal cortex, anterior cingulate, insula, orbitofrontal cortex, and striatum. They will use tractography and tract profiling to map wiring and measure functional and effective connectivity during the task to link circuit differences with persistent avoidance behaviors.

Who could benefit from this research

Good fit: Adults 18–35 with a confirmed diagnosis of OCD who are willing to undergo MRI and behavioral testing, including those who are unmedicated or taking SSRIs/clomipramine.

Not a fit: People older than 35, those with MRI contraindications (like certain metal implants or pregnancy), or those taking other psychotropic medications may not qualify or benefit from this project.

Why it matters

Potential benefit: Findings could point to specific brain circuit targets for therapies (for example, brain stimulation or targeted behavioral treatments) that reduce avoidance and OCD symptoms.

How similar studies have performed: Previous imaging work has linked these brain regions to OCD and some circuit-based treatments (like DBS or TMS) have helped select patients, but this detailed connectivity mapping in young adults is a more focused, developing approach.
