What is Hydrocephalus?
The word hydrocephalus is formed by the combination of the two Greek words for “water” and “head”.

Hydrocephalus has traditionally been referred to as “water on the brain.” In fact, it refers to the build up of excess cerebrospinal fluid in the brain.

Hydrocephalus can be congenital (acquired at birth) or acquired (occurs as a result of an event whether a disease, accident or infection).

Hydrocephalus can either  be communicating (meaning there is no obstruction of the flow of the cerebrospinal fluid but there is mal-absorption) or obstructive (when there is a blockage of the cerebrospinal fluid flow).

Hydrocephalus in the elderly is called normal pressure hydrocephalus.
