Do babies with anencephaly feel pain?

A baby born with anencephaly is usually blind, deaf, unconscious, and unable to feel pain. Although some individuals with anencephaly may be born with a rudimentary brain stem, the lack of a functioning cerebrum permanently rules out the possibility of ever gaining consciousness.

Can anencephaly be detected at 12 week scan?

Fetuses with anencephaly are correctly identified at 12 to 13 weeks gestation. Anencephaly occurs in absence of the cranial vault. Ultrasound findings can be normal until onset of ossification has definitely failed. A first trimester scan at 12 to 13 weeks allows reliable diagnosis and active management of anencephaly.
