The effects of Spina Bifida are different for every person. Up to 90% of children with the most severe form of Spina Bifida have hydrocephalus (excess fluid build-up on the brain) and must have surgery to insert a “shunt” that reduces the pressure on the brain and helps drain the fluid. The shunt stays in place for the lifetime of the person. Other conditions can include full/partial paralysis, bladder and bowel control difficulties, learning disabilities such as attention deficit hyperactivity disorder (A.D.H.D.) and hand-eye coordination, depression, latex allergy and social and sexual issues.
