serious birth defects that involve incomplete development of the brain, spinal cord and/or protective coverings for these organs.
Abnormalities of the spinal cord, including anencephaly and spina bifida.
The neural tube develops into the spinal cord and brain. Defects occur when the neural tube fails to close completely during the early stages of pregnancy.
problems in the development of the spinal cord and brain in an embryo, such as the failure of the spine to enclose the spinal cord (spina bifida) and the failure of the brain to develop (anencephaly)
an abnormality of the spinal cord or brain
Abnormalities of the central nervous system, such as the hydrocephalus and spina bifida.
defects of the fetal brain or spine.
any defect of the brain and spinal cord that is caused by failure of the neural tube to close during growth during pregnancy.
abnormalities arising during early fetal development when the neural tube—the precursor of the spinal cord and brain—does not form correctly. Can cause absence of the brain ( anencephaly) or spina bifida (open spine defect).
These defects include problems stemming from fetal development of the spinal cord, spine, brain, and skull, and include birth defects such as spina bifida, anencephaly, and encephalocele. Neural tube defects occur early in pregnancy at about 4 to 6 weeks, usually before a woman knows she is pregnant. Many babies with neural tube defects have difficulty walking and with bladder and bowel control.
Birth defects that result from improper development of the brain, spinal cord, or their coverings.
Any of a group of congenital malformations that involve the skull and the spinal column. Most commonly it involves the failure of the neural tube to close properly during embryonic development. High levels of alphafetoprotein in the amniotic fluid can reveal potential problems prenatally, and the fetus can be scanned using ultrasound. Immediate surgical repair is required.
A set of birth defects that result from failure of the neural tube to close in utero. Two of the most common NTDs are anencephaly (absence of the majority of the brain) and spina bifida (incomplete development of the back and spine).
the neural tube is a structure that forms in the first few weeks of pregnancy and eventually becomes the child's spine and spinal cord. Birth defects that occur because this early structure did not close properly are called neural tube defects. The most common neural tube defect is spinal bifida.
Developmental defects caused by failure of the vertebral column to close around the spinal cord; may range from mild to severe.
Congenital defect caused by failure of the neural tube to close during embryonic growth such as spinal bifida, cleft lip, and cleft palate.
A group of birth defects that affect the backbone and sometimes the spinal chord.
Abnormalities in the spinal cord.
Normally the closure of the neural tube occurs around the 30th day after fertilization. However, if something interferes and the tube fails to close properly, a neural tube defect will occur. Among the most common tube defects are anencephaly, encephalocele, and spina bifida.
