It can be controlled, but usually not cured. In an adult, the skull is rigid and cannot expand, so the pressure in the brain may increase profoundly. When an injury or illness alters the circulation of CSF, one or more of the ventricles becomes enlarged as CSF accumulates. The average adult produces about one pint of CSF daily. It flows between the cranium and spine to regulate changes in pressure within the brain. ![]() It acts as a vehicle for delivering nutrients to the brain and removing waste and.It acts as a "shock absorber" for the brain and spinal cord. ![]() Although hydrocephalus often is described as "water on the brain," the "water" is actually CSF - a clear fluid surrounding the brain and spinal cord.

The term hydrocephalus is derived from two words: "hydro," meaning water, and "cephalus," referring to the head.
