Prenatal Substance Exposure
Fetal exposure to maternal drug and alcohol use which can significantly increase the risk for developmental and neurological disabilities. The effects can range from severe (neurological damage and growth retardation) to minor (resulting in normal outcomes). Infant and child long-term development depends not only on the prenatal exposure (type of drug, amount, length of time of use), but on factors related to the child's own biological vulnerability and environmental conditions.
