anencephaly

(an?en-sef'a-le) [Gr. an-, not, + enkephalos, the brain] Congenital absence of the brain and cranial vault, with the cerebral hemispheres missing or reduced to small masses. This condition is incompatible with life. In the U.S., it is present in about 11 births out of 100,000. This defect results from the lack of closure of the anterior neural tube. Like other neural tube defects, the risk for anencephaly can be reduced with folic acid supplementation (800 mg daily) taken by women before and during pregnancy. See: neural tube defectanencephalicanencephalus (an?en-se'fal-ik) (an?en-sef'a-lus), adjective
