Hydrocephalus is
Normal pressure hydrocephalus is a condition in which intracranial pressure is intermittently elevated. Impaired CSF absorption is proposed to be one mechanism, which can occur after damage to the arachniod villi following meningitis.
Progressive dementia, urinary incontinence, and gait disturbance are usually present.
Spinal tap reveals normal pressure, but MRI or CT demonstrates ventricular enlargement.
Shunting from the ventricles to the peritoneal cavity or venous system can reduce ventricular size and reduce symptoms.
In obstructive hydrocephalus, CSF outflow is blocked, typically within the cerebral aqueduct (of Sylvius).
