Commonly referred to as water on the brain normal pressure hydrocephalus NPH is a condition where extra spinal fluid gets trapped in the brain instead of traveling through the brain and to the spinal column. Increased ICP stimulates the vagus nerve which contributes to a drop in the heart rate.

This is a medical emergency. The triad of symptoms is often associated with the aging process and a majority of the NPH population is older than 60 years.
Noncommunicating hydrocephalus generates pressure differentials within the brain. Uncorrected bleeding diathesis. Communicating occurs when there is an impaired resorption of cerebrospinal fluid usually at the level of the arachnoid villi.

Dementia apraxic gait and urinary incontinence. This occurs from an irregularity in the production and absorption of the fluid which causes an increase in intracranial pressure as the fluid builds up.
