anencephaly's Usage Examples:

One such congenital brain anomaly, anencephaly (literally "without brain") results when the topmost portion of the tube fails to close and the brain does not develop.

Prenatal diagnosis of neural tube defects causing anencephaly or meningomyelocele is possible through ultrasound examination and maternal blood testing for alpha-fetoprotein, which is almost always elevated.

Genetic counseling is advisable for parents who have had one child with anencephaly, since the likelihood of having another is increased.

Fewer than half of babies with anencephaly are born alive, and survival beyond the first month is rare.

Low levels of folate are linked to serious neurological birth defects including spina bifida and anencephaly.

These types of defects include spinal column defects (spina bifida) and anencephaly (a severe and usually fatal brain abnormality).

If this tube forms incompletely during the first few months of pregnancy, a serious, and often fatal, defect results in spina bifida or anencephaly (formation of the head without the brain).

Some congenital brain anomalies, such as anencephaly, are not compatible with life, and fetuses affected by them will die.
