Neural tube defect
Ultrasound and the Fetal Brain: The most common type of anencephaly, where the brain has entirely failed to form, except for the brain stem. Some researchers have also suggested the possibility of a genetic component, though only one case has been documented in which a family has been presented this diagnosis for more than one child.
Infants born with this condition are born without the main part of the forebrain—the largest part of the cerebrum—and are usually blind, deaf and unconscious. Brain death is another source of support for organ donation. The association seen between reduced neural tube defects and folic acid supplementation is due to a gene-environment interaction such as vulnerability caused by the CT Methylenetetrahydrofolate reductase MTHFR variant.
Medical genetics ; pediatrics. Encephaloceles are characterized by protrusions of the brain through the skull that are sac-like and covered anencephayl membrane. Views Read Edit View history.

Neural tube defects resulted in 71, deaths globally in In addition, the central canal is bloated and forms a cyst. Inthe United States Food and Drug Administration published regulations requiring the addition of folic acid to enriched breads, cereals, flour and other grain products.
Supplementing folic acid during pregnancy reduces the prevalence of NTDs by not exposing this otherwise sub-clinical mutation to aggravating conditions. The two most common neural tube defects are spina bifida and anencephaly.
