Obsessive Compulsive Disorder study: Deep Brain Stimulation
Official title Neurophysiological Investigation of the Approach-avoidance Axis in OCD: Applications to Neuromodulation
ClinicalTrials.gov ID: NCT06596447
What this study is testing
- What it's testing
- The study aims to see how brain activity in the ventral striatum relates to decisions to approach rewards or avoid threats, and how this changes with DBS treatment.
- Who it's for
- Adults with obsessive‑compulsive disorder who qualify for surgical evaluation for DBS.
- What's involved
- Participants will have DBS leads implanted and will attend clinic visits and home monitoring. They will complete tasks, exposure therapy, and wearables that record brain signals and behavior.
- Time commitment
- The study lasts 12 months, with clinic visits at 7 timepoints: before surgery, 1 day before activation, immediately after, and at 2 weeks, 3 months, 6 months, and 12 months after DBS starts.
