Too much folic acid during pregnancy

如果科學界普遍認為太少的葉酸確實導致嬰孩的神經管缺陷，那麼過多的葉酸導致神經組織損傷，繼而引致自閉症似乎是合理的。

If it is true that too little folic acid results in nervous tissue damage, as is accepted by the scientific community in regard to neural tube defects (NTDs), then it seems plausible (似合理的) that too much folic acid may result in nervous tissue damage associated with autism.
