Hydrocephalus is further classified as communicating and noncommunicating. In communicating hydrocephalus , the obstruction occurs in the subarachnoid space. Noncommunicating hydrocephalus means the obstruction is located within the ventricles. Intracranial pressure is usually increased and significant neurological abnormalities may develop, including damage to brain tissue. This type is most commonly caused by stroke or traumatic brain injury.
Normal pressure hydrocephalus enlarges the ventricles without increasing pressure in the brain.
This type most commonly affects older people. Find a neurologist near you. Join a live chat or threaded forum. All Rights Reserved Contact the webmaster with any technical issues.
