Hydrocephalus is a condition thatâs also known as water on the brain. Hydrocephalus can occur in older children and adults, particularly older adults.
Normal pressure hydrocephalus is a brain disorder in which excess cerebrospinal fluid accumulates in the brain's ventricle, causing thinking and reasoning problems, difficulty walking and loss of bladder control. About.PH is called normal pressure because despite the excess fluid, cerebrospinal fluid pressure as measured during a spinal tap is often normal. As brain ventricles enlarge with the excess cerebrospinal fluid, they can disrupt and damage nearby brain tissue, causing symptoms of NPH.
