Normal Pressure Hydrocephalus Topic Guide
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.

Treatment includes implanting a shunt with a valve that drains the excess fluid when the pressure reaches a certain point.
