Hydrocephalus is also known as water on the brain. It is a condition in which an accumulation of cerebrospinal fluid (CSF) occurs within ventricles (fluid-containing cavities) of the brain and may increase pressure within the head. Hydrocephalus can happen at any age, but it occurs more frequently among infants and adults 60 and over. Older people may have headaches, double vision, poor balance, urinary incontinence, personality changes, or mental impairment. In babies, it may be seen as a rapid increase in head size. Other symptoms may include vomiting, sleepiness, seizures, and downward pointing of the eyes. Hydrocephalus can be congenital or acquired.
Hydrocephalus has two base causes that are the bloodstream is not fully absorbing the fluid due to a damaged filter in the brain and / or the flow of fluid within the ventricles is blocked
