Overview

Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain.

Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column. But the pressure of too much cerebrospinal fluid associated with hydrocephalus can damage brain tissues and cause a range of brain function problems.

Hydrocephalus can happen at any age, but it occurs more frequently among infants and adults 60 and over. Surgical treatment for hydrocephalus can restore and maintain normal cerebrospinal fluid levels in the brain. Different therapies are often required to manage symptoms or problems resulting from hydrocephalus.
