Water on the brain: a guide to hydrocephalus
Also called as ‘water on the brain’, hydrocephalus is an excessive accumulation of cerebrospinal fluid on the brain, causing abnormal dilation of brain spaces known as ventricles. This exerts a damaging pressure on the brain, which usually needs to be treated with a bypass system or catheter with a valve. If left untreated, it can be deadly.
