Anencephaly

[Zipporah Schumaker]

Anencephaly is absence of the cerebral hemispheres.

The absent brain is sometimes replaced by malformed cystic neural tissue, which may be exposed or covered with skin. Parts of the brain stem and spinal cord may be missing or malformed. Infants are stillborn or die within days or weeks.

Treatment of anencephaly is palliative only.

[Marquetta]

A severe congenital condition in which a large part of the skull is absent along with the cerebral hemispheres of the brain.

[Lizzy Liz]

One of the worst fetal issues where the brain and the top part of the skull is missing. This [oddity] is caused because of the lack of [folic] acid between the second and whole third month of embryo development.
This means that the neural tube aka. the [spinal cord] and the backbone does not close properly.
Anencephales or anencephalics look like frogs with protuberant eyes, and have got often an encephalocele at the occipital (missing) area, facial traits like zombies... Yuck!
