Hydrocephalus
Overview
The symptomatic buildup of cerebrospinal fluid (CSF) inside the brain ventricles is known as hydrocephalus. This buildup might be due to a blockage in the normal flow of CSF, issues with absorption into the venous system by arachnoid granulations, or excessive CSF production. Dandy defined hydrocephalus as communicative and noncommunicating (obstructive), and several other categories have subsequently been offered.
There are four forms of hydrocephalus in adults: obstructive, communicative, hypersecretory, and normal pressure hydrocephalus (NPH). Congenital or developmental hydrocephalus is common at birth and is frequently associated with a genetic abnormality or spinal dysraphism.
