can spina bifida effect mental retardation?

unfortunately, most babies beside spinal bifidia are aborted as they are stillborn. I envision that if it was a smaller number severe case, in attendance would definitely be mental retardation.
yes.
Nope it can't. some kids near Spina Bidfia don't have Mental retardtion, most do however. But no, Spina Bidfia can't result in Mental retardtion.
