microcephaly
Abnormally small skull
Microcephaly is a medical condition in which the head is abnormally small, typically because the brain has not developed properly.
It can result from genetic abnormalities, infections during pregnancy, or other factors affecting fetal development.
The condition often accompanies developmental delays and intellectual disability.
The Zika virus outbreak raised concerns about microcephaly in newborns.
