Normal Pressure Hydrocephalus

Alternate Names : Hydrocephalus Ex Vacuo

Normal pressure hydrocephalus is a condition in which the cerebral ventricles are enlarged. The cerebral ventricles are cavities within the brain that contain the cerebrospinal fluid.

What is going on in the body?

This condition occurs mainly in older people when the ventricles slowly enlarge. Since the skull is not flexible, the brain thins to allow the ventricle to grow. This allows the pressure within the brain to remain normal.

What are the causes and risks of the condition?

The cause of this condition is unknown. Symptoms will worsen with lack of treatment. When thought processes and control of body movement become impaired, the person is at increased risk of injury from falling. Poor control of bowel and urinary function may result in urinary tract infections and skin breakdown.
