Spina bifida, a common birth defect, can be prevented in up to 70% of cases through maternal folic acid supplementation. The exact protective mechanism involving folate metabolism requires further investigation.

Area of Science:

  • Developmental Biology
  • Public Health
  • Genetics

Background:

  • Spina bifida is a frequent congenital malformation due to incomplete closure of the neural tube.
  • Its etiology is diverse, encompassing genetic and environmental factors, though often idiopathic.
  • Maternal folic acid supplementation significantly reduces spina bifida incidence.

Purpose of the Study:

  • To summarize the current understanding of spina bifida.
  • To highlight the preventive role of folic acid.
  • To outline management strategies for affected individuals.

Main Methods:

  • Review of existing literature on spina bifida etiology and prevention.
  • Analysis of the impact of folic acid supplementation.
  • Description of current surgical and medical management approaches.

Main Results:

  • Up to 70% of spina bifida cases are preventable with periconceptional folic acid intake.
  • The protective mechanism likely involves folate transport and metabolism genes.
  • Surgical intervention is typically neonatal, with ongoing trials for in utero repair.

Conclusions:

  • Folic acid supplementation is a critical preventive measure for spina bifida.
  • Lifelong multidisciplinary medical management is essential for individuals with spina bifida.
  • Further research is needed to elucidate the precise mechanisms of folate's protective effects.
