General Discussion

Anencephaly is a disorder involving the incomplete development of major parts of the brain. Anencephaly is classified as a neural tube defect (NTD), and that term refers to the incomplete development of the brain, spinal cord, and/or their protective coverings. The neural tube is a narrow sheath that is supposed to fold and to close during the third and fourth weeks of pregnancy, in order to form the brain and spinal cord of the embryo. Anencephaly occurs when the head (cephalic) end of this neural tube fails to close, resulting in the failure of major portions of brain, skull and scalp to form.

Infants with anencephaly are born without both a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating part of the brain). Often the remaining rudimentary brain tissue may be exposed, without the protective covering of either bone or skin. Although reflex actions such as breathing and responses to touch or sound may occur, gaining consciousness is almost invariably ruled out.
