Dr. Evelyn Stewart is an Associate Professor in the Department of Psychiatry, University of British Columbia and is the founding director of the Pediatric Obsessive-Compulsive Disorder Clinic and Research Program at BC Children and Women’s Health Centre. She is a clinical, genetic and neuroscience researcher, as well as a child and adolescent psychiatrist.
Her research focuses on biologic, phenotypic, familial, and treatment aspects of childhood-onset neuropsychiatric disorders, such as obsessive-compulsive disorder (OCD). Dr. Stewart has authored over 70 original papers, reviews and chapters on genetic, clinical, and treatment aspects of OCD, Tourette's Disorder, and related illnesses. She sits on the Scientific and Clinical Advisory Board of the International OCD Foundation and was previously on the Medical Advisory Board of the Tourette Syndrome Association of America and Co-director of the International OCD Foundation Genetics Collaborative.
At BCCHR, she leads the BB&D theme and co-leads the MH group.

Current Projects
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.

The goal is to compare neural correlates in CO-OCD and unaffected, at-risk sibling (SIB) groups with matched healthy controls (HC), in order to evaluate both their suitability as trait markers of genetic risk (to better understand the disorder) and their potential utility in clinical settings (to better manage the disorder).

Overcoming the bully that is OCD
We caught up with Dr. S. Evelyn Stewart, medical director of the Provincial OCD Program, an investigator at BC Children’s Hospital and professor at the University of British Columbia, to learn more about Obsessive-Compulsive Disorder and evidence-based treatment for this challenging mental illness.
