neural tube defect
Let an agent explain neural tube defects in general terms, relay types, causes, prevention with folic acid, screening and care from medical and public health sources, describe the named forms and flag the misfiled alias, and distinguish neural tube defects from hydrocephalus alone, tethered cord from other causes and chromosomal conditions, without giving individual medical advice and presenting pregnancy decisions neutrally.

What it is Filled
A birth defect of the brain, spine or spinal cord caused by incomplete closure of the neural tube in the first weeks of pregnancy, including spina bifida, anencephaly and cephalocele or encephalocele, and rachischisis, a severe open spinal defect, with folate-sensitive and rare X-linked forms named in registry aliases; severity varies, and anencephaly and craniorachischisis are lethal forms. The alias parietal foramina names enlarged skull openings from an ossification defect, which is generally not classified as a neural tube defect and appears misfiled, and the alias malformation of the neurenteric canal names a broader group. Taking folic acid before conception and in early pregnancy reduces risk, and many countries fortify flour, while prenatal screening and specialist care support families.
Why it exists Filled
Let an agent explain neural tube defects in general terms, relay types, causes, prevention with folic acid, screening and care from medical and public health sources, describe the named forms and flag the misfiled alias, and distinguish neural tube defects from hydrocephalus alone, tethered cord from other causes and chromosomal conditions, without giving individual medical advice and presenting pregnancy decisions neutrally.
Distinguishing features Filled
- Early pregnancy origin
- Folate-preventable in part
- Range of severity
- Multidisciplinary care
What robots and AI may and may not do Filled
Must not
- Give individual advice on continuing or ending a pregnancy.
- Use stigmatising language about disability.
- Omit prevention advice on folic acid when asked about prevention.
- Blame parents for a defect in their child.
Only with a human decision
- Any medical decision for a pregnancy or newborn.
May
- Explain neural tube defects and the general role of folic acid in prevention, citing health bodies.
- Use respectful, person-first language about people living with spina bifida.
Moral aspects Filled
- Discussions of birth defects touch reproductive choice and disability rights, so care and respect are needed.
- Many defects are preventable through public health measures such as fortification.
Who is affected
- People with spina bifida
- Parents
- Pregnant people
Owners Filled

Nobody owns the condition; clinicians and public health bodies address it.

Direct properties not applicable Not applicable
- neural tube closure: about 28 days after conception note

Recognition optional Filled
- Incomplete closure of the neural tube
- Parietal foramina, rachischisis, cephalocele, neurenteric canal malformation, X-linked neural tube defects, folate-sensitive neural tube defects
