Normal pressure hydrocephalus NPH is a brain disorder in which excess cerebrospinal fluid CSF accumulates in the brain's ventricles, causing thinking and reasoning problems, difficulty walking, and loss of bladder control. Normal pressure hydrocephalus is called "normal pressure" because despite the excess fluid, CSF pressure as measured during a spinal tap is often normal. As brain ventricles enlarge with the excess CSF, they can disrupt and damage nearby brain tissue, leading to difficulty walking, problems with thinking and reasoning, and loss of bladder control. Normal pressure hydrocephalus can sometimes be treated with surgical insertion of a shunt, a long, thin tube that drains excess CSF from the brain to the abdomen. Surgery is most likely to help correct difficulties walking, but thinking changes and loss of bladder control are less likely to improve.

At the University of Florida, all Neurological Surgery physicians treat adult patients with hydrocephalus. Pediatric Neurosurgery Hydrocephalus Brochure. Hydrocephalus results from the excessive accumulation of fluid in the cavities of the brain. In the normal person approximately cc of fluid is produced every hour. This fluid provides a cushioning barrier in which the brain floats. The fluid is also used to carry nutrients to the brain and carry away waste products.

What is hydrocephalus? What are the different types of hydrocephalus? Who gets this disorder? What causes hydrocephalus? What are the symptoms?
Hydrocephalus is a condition that occurs when fluid builds up in the skull and causes the brain to swell. Brain damage can occur as a result of the fluid buildup. This can lead to developmental, physical, and intellectual impairments. It requires treatment to prevent serious complications.
