Normal Pressure Hydrocephalus Normal pressure hydrocephalus is a brain disorder that develops in older adults. Hydrocephalus happens when the drainage of the cerebro-spinal fluid that surrounds the brain and spinal cord is blocked. The fluid builds up in the hollow ventricals inside the brain, and the excess pressure can cause dementia, and physical symptoms similar to Parkinson disease. Treatment includes implanting a shunt with a valve that drains the excess fluid when the pressure reaches a certain point.
