Non-communicating hydrocephalus happens when the flow of CSF is blocked along one or more of the narrow passages connecting the ventricles. The excess fluid increases the size of the ventricles and puts pressure on the brain.

Communicating hydrocephalus is due to reduced absorbance of CSF by the arachnoid villi or rarely due to increased CSF production. To enlist diagnostic evaluation for hydrocephalus.
