Abstract
Youth with anorexia nervosa (AN) have been reported to have high levels of comorbid autism spectrum disorder (ASD) and ASD-like traits suggesting a potential shared underlying neurodevelopmental or genetic link between the disorders. Youth with comorbid AN and ASD symptomatology generally require more intensive treatment and have worse psychological outcomes following treatment. To date, no Canadian national guidelines exist for the treatment of this comorbidity. An informal survey of tertiary paediatric eating disorder programs across Canada revealed that centres do not routinely screen for ASD at intake and few offer any treatment modifications for youth with AN and suspected/diagnosed comorbid ASD. This represents a significant care gap for this clinical sub-population and an important area for future study and healthcare provider training.
