Andrée-Anne Ledoux

Scientist CHEO Research Institute

Dr. Ledoux is a Scientist at the CHEO Research Institute and Assistant Professor for the Cellular Molecular Medicine Department at University of Ottawa. Dr. Ledoux has a PhD in Experimental Psychology and Behavioural Neuroscience.

Dr. Ledoux and her team is interested in developing and testing management protocols that target neuronal repair in the hopes of reducing the risk of persistent post-concussive symptoms, reducing the recovery period, and promoting resiliency and neural protection in pediatric concussion. She is interested in identifying recovery neural correlates that can be used as recovery biomarkers in concussion and investigating how behavioural treatments can modify these biomarkers. She is currently investigating the acute and subacute clinical, neuropsychological and neurophysiological recovery processes of two different behavioural management protocols: early return to physical activity and mindfulness-based intervention with MRI. Given the extensive brain maturation and significant functional development that occurs throughout childhood in addition to the sex differences that exist throughout development, she also explores age and sex-based differences in all of her concussion-related studies. Together with a multidisciplinary approach, cutting edge techniques and national/international collaborations she hopes to reduce the impact of concussion in children and adolescents and their family.
