Hydrocephalus that is not treated may cause death, according to the National Institute of Neurological Disorders and Stroke. Normal-pressure hydrocephalus, the type of condition suffered by adults, that is diagnosed and treated early often leads to good recovery outcomes.
Hydrocephalus causes a buildup of fluid in the ventricles of the brain, leading to an increase in pressure in the skull, reports Medical News Today. The skull then presses on the brain tissue, which may cause head enlargement, convulsions or brain damage. The pressure in the brain causes a variety of symptoms, including headaches, vomiting, blurry vision, cognition issues and difficulty walking. Normal-pressure hydrocephalus, occurring most often in people 50 years or older, usually results from a stroke or head injury.
