Abstract
Autism is an early-onset developmental disability that causes neurological deficits in children, affecting their ability for social interaction, language, imagination, communication and cognition. The etiology of autism
is not well established but it is generally considered as a multifactorial disorder. Current theories include the environmental, genetic, immune, neurochemical, developmental psychology, and other unknown factors. Toxic metals may play a role in pathogenesis of autism. The aim of the present study was to measure serum levels of lead in the blood of autistic children and to compare to healthy children of comparable age and sex as a control group. The study was conducted on 30 children with ASD aged 3-15 years (23 males, 7 females), diagnosed according to the DSM-V criteria and 30 clinically healthy children of comparable age and sex as a control group.
