8. Missing brain pieces
Neural tube defects can come in several forms, one of the most notable symptoms of Anencephaly however is missing parts of the brain. During gestation, the neural tube of the fetus will form and develop into the brain and bone of the skull. This tube will also form the backbones and the spinal cord. With Anencephaly, the neural tube fails to finish forming. This results in parts of the brain not developing or under developing. It also prevents the skull bones from forming over the back of the head and sometimes the top and sides as well.
Most fetuses afflicted with Anencephaly develop a cerebrum which is the part of the brain that controls thought and coordination. The forebrain or cerebellum is another part that often fails to develop creating a noticeable space where it belongs.
Due to these parts of the brain being absent, Anencephaly patients often are stillborn or pass away shortly after birth.
