Examples of neural tube defects

The neural tube is an early structure that develops into the brain and spinal cord. Spina bifida occurs when part of the spinal column does not close fully; its effects vary according to the location and the nerves involved. Anencephaly is a severe defect in which major parts of the brain and skull do not develop. Encephalocele involves brain tissue and its coverings protruding through an opening in the skull.

These conditions are usually considered during pregnancy screening and diagnostic discussions. A scan may show structural differences, but not every detail can be predicted before birth. A finding requires careful explanation from a fetal medicine or obstetric team.

If you are planning a pregnancy, arrange preconception care to review medicines, health conditions, and folic acid advice. During pregnancy, attend scheduled scans and share questions about what a result means. If a scan raises concern, ask about repeat imaging, specialist referral, birth planning, and support for you and your family.

Neural tube defects do not usually cause a symptom that a pregnant person can identify at home. Seek maternity advice for any urgent pregnancy concern such as bleeding, severe pain, fluid leakage, or reduced fetal movements according to your care team’s instructions. For questions about development, request a planned appointment rather than trying to interpret a scan image alone.

Ask which part of development appears different, how confident the finding is, whether further imaging is needed, and what care may be available before and after birth. Discuss folic acid, recurrence concerns, and emotional support if you have had a previous affected pregnancy.
