Abstract

Autism spectrum disorders (ASD) may present with macrocephaly. Few studies have analyzed the association with psychiatric comorbidity. Participants were 94 children with any ASD with an age range from 2 to 16 years (Mdn 6 years), 82% were boys. It was found that 20% of the sample had macrocephaly and 1% microcephaly. There was no association between the presence of macrocephaly and subtype of ASD. The most associated comorbidity was attention-deficit/hyperactivity disorder (ADHD) 54.2%, followed by specific phobia 34%, dysthimia 29.7%, oppositional defiant disorder 13.83% motor tics 11.7%, separation anxiety 9.5% and Gilles de la Tourette 8.5%. In conclusion, macrocephaly and psychiatric comorbidity in this clinical sample of children with ASD is similar to the international literature results.
