Definition
By Mayo Clinic staffHydrocephalus occurs when excess fluid builds up in your brain, most often because of an obstruction preventing proper fluid drainage. The excess fluid can compress surrounding, fragile brain tissue, causing brain damage. Left untreated, hydrocephalus can be fatal.
Once known as "water on the brain," hydrocephalus is sometimes present at birth, although it may develop later. About 1 out of 500 children is born with the disorder. The outlook if you have hydrocephalus depends on how quickly the condition is diagnosed and whether any underlying disorders are present.
