The objective of our study is to estimate the prevalence of comorbid psychiatric disorders in a sample of children with autism spectrum disorders (ASD) recruited from three Arab countries. We also examine the relationship between comorbidity and children's cognitive functioning and gender. Children who received a diagnosis of ASD (n = 60) from a…

Background: Many disorders in childhood and adolescence were already present in the preschool years. However, there is little empirical research on the prevalence of psychiatric disorders in young children. A true community study using structured diagnostic tools has yet to be published. Methods: All children born in 2003 or 2004 in the city of…
