an accumulation of csf which exerts pressure is known as _____________________.
The term hydrocephalus is a neurological condition, where there is an accumulation of cerebrospinal fluid (CSF) in the brain.

Increase in the cerebrospinal fluid widens the ventricular spaces in the brain and exerts pressure on the brain tissues.
