a developmental defect in which the brain fails to develop

A type of neural tube disorder where the baby's brain does not form. This is caused by a failure of the neural tube to close properly very early in the babies' development. Anencephalic babies often die prior, but can live a few hours after being born. Studies show that the presence of folic acid in the mother's blood at the time of conception greatly reduces the number of neural tube disorders. It does not, however, prevent them entirely. In Westernized countries most women get sufficient folic acid in their diet and the numbers of the disorders have not dropped dramatically despite huge campaigns.

A neural tube opening located at the base of the brain which is not compatible with life. Stillbirth or neonatal death is the most likely outcome.

A birth defect resulting in the abnormal development of the baby's brain and skull.

A severe congenital defect in which the fetus has no brain.

a defect in brain development resulting in small or missing brain hemispheres

a defect in the closure of the neural tube during foetal development. The neural tube is a narrow channel that folds and closes between the 3rd and 4th weeks of pregnancy to form the brain and spinal cord of the embryo. Anencephaly occurs when the "cephalic" or head end of the neural tube fails to close, resulting in the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating part of the brain) and do not survive for long after birth.

neural tube defect where the brain and skull do not form completely. Affected babies die, either before birth (stillbirth) or shortly thereafter. Because the brain is only partly formed, affected newborns cannot control basic life functions like breathing.

A condition in which the brain fails to completely develop or is absent.

See Neural Tube Defect.

A fatal defect in which the top of the neural tube fails to close (see NTD) and the brain does not develop properly.

Absence of the greater part of the brain, often with skull deformity.

Congenital absence of the skull, with cerebral hemispheres completely missing or reduced to small masses attached to the base of the skull. Anencephaly is not compatible with life.

A rare condition in which the baby's brain does not develop properly while in the womb, resulting in little or no brain and a malformed skull.

A neural tube defect (NTD) that occurs when the cephalic (head) end of the neural tube fails to close, usually between the 23rd and 26th days of pregnancy, resulting in the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain, the largest part of the brain consisting mainly of the cerebrum , which is responsible for thinking and coordination. The remaining brain tissue is often exposed; it is not covered by bone or skin. See the entire definition of Anencephaly

A birth defect resulting in babies being born with underdeveloped brains and incomplete skulls. most babies born with anencephaly do not survive more than a few hours after birth.

A fatal neural tube defect in which the fetus's head and brain fail to develop normally and the neural tube remains open at the top.

Absence of the cerebrum, cerebellum, and flat bones of the skull in the foetus (born without a brain).

A rare birth defect resulting in little or no brain and a malformed skull.

A neural tube defect involving severe structural defects of the brain and skull. Fetuses with anencephaly do not survive.

A congenital defect in the development of the brain. Bones in the skull and parts of the brain may be missing or poorly developed. An infant with anencephaly will either be stillborn or will die shortly after birth.

Absence of development of the brain and related structures which leads to stillbirth or death soon after birth.

open neural tube defect with absent brain development, leading to early death

A rare birth defect in which the baby has a malformed skull and little or no brain.

a condition that is present at birth and affects the formation of the brain and the skull bones that surround the head, resulting in only minimal development of the brain. There is no bony covering over the back of the head and there may also be missing bones around the front and sides of the head.

A developmental defect characterized by incomplete development of the cerebral hemispheres and cranium.

Birth defect in which all but the most primitive parts of the brain, skull, and spinal cord fail to form in the embryo.

a fatal birth defect in which the brain and spinal cord have failed to develop, resulting in the absence of a portion of the skull and brain

Abnormal development of the brain in the fetus accompanied by absence of the bones of the cranial vault. Children born with this severe disorder die shortly after birth. Measurement of maternal blood and amniotic fluid levels of alpha-fetoprotein (AFP) can help diagnose this condition and other neural tube defects. See alpha-fetoprotein.

Anencephaly is a cephalic disorder that results from a neural tube defect that occurs when the cephalic (head) end of the neural tube fails to close, usually between the 23rd and 26th day of pregnancy, resulting in the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain, the largest part of the brain consisting mainly of the cerebral hemispheres (which include the isocortex, which is responsible for higher level cognition, i.e., thinking). The remaining brain tissue is often exposed - not covered by bone or skin.
