hydrocephalus
Pronunciation: hahy-droh-SEF-uh-luhs
Medical condition characterized by abnormal accumulation of cerebrospinal fluid in brain ventricles.
Full Definition
Hydrocephalus is a neurological condition resulting from the abnormal accumulation of cerebrospinal fluid (CSF) within the brain's ventricular system, leading to increased intracranial pressure and potential brain damage. The condition can be congenital or acquired, and may result from overproduction of CSF, obstruction of CSF flow, or inadequate CSF absorption. Types include communicating hydrocephalus (where CSF flow is not blocked) and non-communicating or obstructive hydrocephalus (where flow is blocked). Treatment typically involves surgical intervention, most commonly the placement of a shunt system to drain excess CSF to another body cavity where it can be absorbed.
