Prenatal alcohol exposure is a preventable cause of birth defects, including mental retardation and neurodevelopmental deficits. Since the initial recognition in 1968 of the multiple effects that alcohol can have on the developing fetus [1] and the subsequent delineation in 1973 of fetal alcohol syndrome (FAS), [2] it has become clear that prenatal alcohol exposure can be associated with a wide range of abnormalities. [3] More than 80% of children with FAS demonstrate prenatal and postnatal growth deficiency, mild to moderate mental retardation, microcephaly, infantile irritability, and characteristic facial features.
