Definition
Anencephalous is a synonym for anencephalic, describing the condition where a baby is born without major portions of the brain and skull. It refers to the same severe birth defect and carries the same implications. Like anencephalic, it indicates that the brain did not develop properly during pregnancy, leading to a fatal condition. Prenatal screening can usually detect anencephalous pregnancies. The term emphasizes the absence of a significant portion of the brain.
