Biomarkers of awareness and response to treatment in obsessive-compulsive disorder (BARTOC): Implementing EEG-based biomarkers of cognitive control in a pilot study of nitrous oxide inhalation vs placebo in OCD

This project is focused on developing EEG-based measures of cognitive control and conflict processing in patients with obsessive-compulsive disorder (OCD). OCD is characterized by recurrent, intrusive, and distressing thoughts, and patients are often limited by rigid, inflexible behavioral routines as well as poor clinical insight into their illness. Van Roessel and his team hope to characterize circuit-level biomarkers for clinical insight in OCD patients and to assess how they are impacted by a novel rapid-acting treatment.
