Is it more likely for people w/congenital or acquired hydrocephalus to eventually not be dependent on shunts anymore? communicating/noncommunicating?

Hydrocephalus: The reason the people with acquired hydrocephalus come for treatment is their disease which is treated with a shunt. These individuals will require the shunt life long. The congenital hydrocephalus group have less than a 5% chance of no longer requiring a shunt. Shunts work well and there are athletes, scientists, accountants, etc with functioning shunts.
