Unrecognized comorbid autism spectrum disorder in children initially diagnosed with only attention deficit hyperactivity disorder.

Abstract

The present study examined the prevalence of autism spectrum disorder (ASD) in intellectually capable children with attention deficit hyperactivity disorder (ADHD). Retrospective chart review on 103 children (mean age= 7.83±1.72 years female=15.53%), without intellectual disability, who were diagnosed with only ADHD were done. Among the 103 children 27 children (26.21%) were later co-diagnosed with ASD. The results of the present study provide helpful insights in accurate recognition of co-occurring ASD in intellectually capable children diagnosed with ADHD. The potential for the coexistence of ASD should always be given careful consideration when examining children with ADHD.
