Anencephaly

Anencephaly

Anencephaly is a neural tube defect that occurs when the head end of the neural tube fails to close, usually during the 23rd and 26th days of pregnancy, resulting in the absence of a large and important portion of the brain and skull. Infants born with this birth defect are born without the main section of the forebrain-the largest part of the cerebrum- and are usually blind, deaf and/or unconscious. The lack of a large portion of a functioning cerebrum will ensure that the infant will never gain consciousness. Infants are either stillborn or usually pass away within a few hours or days after the birth.
