Then they underwent complete assessment of mental age using Stanford-Binet intelligence scale, childhood autism rating scale to outline severity of ASD in cases and exclude presence of autistic features in controls.
Results:There is a statistically significant difference between both groups regarding mother,and father education, fathers’ age at conception, family history of psychiatric disorders, history of induction of ovulation, hypertension during pregnancy, folic acid supplementation during 1st trimester of pregnancy, use of anti D, history of postnatal hypoxia, admission to NICU and feeding type. A significant difference between them concerning reaction to others and delayed developmental milestones was found. About 63% and 58% had severe autism and mild to severe mental retardation respectivey. Paternal age, positive family history of psychiatric diseases, postnatal hypoxia significantly increased risk of ASD. Folic acid supplementation during 1st trimester of pregnancy significantly decreased risk.
