Neural tube defects (NTDs) are catastrophic birth disorders that happen when the neural tube, which is the early structure that becomes the brain and spinal cord, doesn't seal properly during the first month of pregnancy. These anomalies usually happen in the brain and spine, which can cause problems including spina bifida, anencephaly, and encephalocele.

Different kinds and traits

Spina bifida is when the spinal column doesn't close all the way, which can lead to nerve weakening, paralysis, bladder and bowel difficulties, and even hydrocephalus. Anencephaly, when most of the brain and skull don't grow, generally kills the baby soon after birth. Encephalocele is when brain tissue pushes through a hole in the skull. It is typically connected to developmental delay and seizures.

Reasons and ways to stop it

NTDs are caused by a combination of genetic predisposition and environmental influences, particularly folate (vitamin B9) deficiency before and during early pregnancy. Diabetes, obesity, some antiepileptic medicines, and infections in the mother can potentially raise the risk. Women of reproductive age should take folic acid supplements every day (400–800 mcg/day) and eat enough leafy greens, legumes, and fortified cereals to lower the risk of these abnormalities.
