Is spina bifida caused by a spinal cord injury or birth trauma?

Are hemiplegic children impaired on one side or on both sides?

More than just "impaired."

Please repost if you have further questions.

Spinal bifida is due to lack of folic acid, or lack of metabolism of folic acid in the fetus at a very early state. There is a hereditary linkage.

Hemiplegic: one side is paralyzed.
