Research Focus

Neural Correlates in Childhood-onset OCD: The goal of this study is to evaluate for neurocognitive and neurosoft sign state and at-risk trait markers for OCD, by examining affected, at-risk and healthy youth.

Brain Function and Structure in Pediatric Obsessive Compulsive Disorder: The goal of this study is to examine the cortical structure and functional activation in the regions implicated in OCD in OCD-affected, OCD-unaffected siblings, and healthy children and adolescents. A planning task conducted pre- and post-symptom provocation will be used to examine the impact of symptoms on executive function. In addition, DTI will record white matter structure and organization.
