- cranial (anterior) neuropore closes before caudal (posterior)
- failure to close - Neural Tube Defects (NTD), severity dependent upon level, spina bifida anancephaly (More? [neuron2.htm Neural Abnormalities])
- found that supplementation of maternal diet with folate reduces incidence of NTDs
- A randomised controlled trial conducted by the Medical Research Council of the United Kingdom demonstrated a 72% reduction in risk of recurrence by periconceptional (ie before and after conception) folic acid supplementation (4mg daily).
- Women who have one infant with a neural tube defect have a significantly increased risk of recurrence (40-50 per thousand compared with 2 per thousand for all births)
