Normal pressure hydrocephalus

Health problems

Normal-pressure hydrocephalus (NPH), also called communicating hydrocephalus and malresorptive hydrocephalus, is a condition in which excess cerebrospinal fluid (CSF) occurs in the ventricles, and with normal or slightly elevated cerebrospinal fluid pressure. As the fluid builds up, it causes the ventricles to enlarge and the pressure inside the head to increase, compressing surrounding brain tissue and leading to neurological complications. The disease presents in a classic triad of symptoms, which are urinary incontinence, dementia, and gait deviations. The disease was first described by Hakim and Adams in 1965.
