Answer

Incidence of human hydrocephalus presents a bimodal age curve. One peak occurs in infancy and is related to the various forms of congenital malformations and premature birth. Another peak occurs in adulthood, mostly resulting from NPH. Adult hydrocephalus represents approximately 40% of total cases of hydrocephalus.

The outcome of pediatric hydrocephalus has been studied frequently, but much remains unresolved about long-term and social outcomes. [10]
