Clinical characteristics of adults suffering from high-functioning autism and comorbid obsessive-compulsive disorder

Abstract

Autism spectrum disorder (ASD) is a very heterogeneous disorder. Obsessive compulsive disorder (OCD) comorbidity, frequent in ASD, could be useful to define a specific ASD subtype. Our objective was to explore if adults with ASD and comorbid OCD could present a specific clinical profile of ASD in 89 high functioning-adult ASD patients. We found that adults with ASD and comorbid OCD showed a lower verbal IQ and a more severe impairments in social cognition. ASD with comorbid OCD present a specific clinical profile which could constitute a possible subtype of ASD.
