Anencepyhaly 无脑儿

The absence of the fetal cranial vault in anencephaly is shown here. The incidence of anencephaly, one form of neural tube defect, has been reported to occur as frequently as 1 to 5 in 1000 live births in the past. However, dietary folic acid supplementation by mothers-to-be before and during pregnancy can reduce the incidence of such birth defects. The rate of anencephaly is now less than 1 in 10,000 live births in some places.
