The Hydrocephalus Association defines hydrocephalus as:
Hydrocephalus comes from Greek words:
hydro means water, cephalus means head. Hydrocephalus is an abnormal accumulation of fluid, cerebrospinal fluid, or CSF within
cavities called ventricles inside the brain. This condition may occur at any age. CSF is produced in the ventricles, circulates
through the ventricular system in the brain and is absorbed into the bloodstream. CSF is in constant circulation and has many
functions. It surrounds the brain and spinal cord and acts as a protective cushion against injury. CSF contains nutrients
and proteins that are needed for the nourishment and normal function of the brain. It carries waste products away from surrounding
tissues. Hydrocephalus occurs when there is an imbalance between the amount of CSF that is produced and the rate at which
it is absorbed. As the CSF builds up, it causes the ventricles to enlarge and the pressure inside the head to increase.
Wikipedia defines hydrocephalus as:
Hydrocephalus (pronounced /ˌhaɪdrɵˈsɛfələs/), also known as Water on the Brain, is a medical condition. People with hydrocephalus have an abnormal accumulation
of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain. This may cause increased intracranial pressureinside the skull and progressive enlargement of the head, convulsion, and mental disability. Hydrocephalus can also cause death.
