Hydrocephalus is a condition that occurs when there is too much cerebrospinal fluid in the ventricles (cavities) of the brain.
Cerebrospinal fluid (CSF) is produced in the brain, and is needed by the body to protect the brain and spinal cord, and carry away waste from brain cells. It flows continuously through the ventricles of the brain and over the surface of the brain and spinal cord. Any excess CSF usually drains away from the brain and is absorbed by the body. For people with hydrocephalus, this doesn't happen, and the fluid instead builds up in the ventricles.
Too much cerebrospinal fluid puts a harmful amount of pressure on tissues in the brain - treatment is needed to release this pressure. Hydrocephalus can be congenital (present at birth), or develop later in childhood or adulthood. Normal pressure hydrocephalus (NPH) is a type of hydrocephalus, which usually develops in people over 60, because the drainage of the CSF gradually becomes blocked.
Hydrocephalus affects about one in 1,000 people. It's most common in childhood but can affect adults too.
How is it diagnosed?
Symptoms including an enlarged head and changes to the nervous system suggest the diagnosis.
Tests include ultrasound and CT or MRI scans of the head and skull x-rays. Occasionally, a lumber puncture may be used.
What's the treatment?
The aim of treatment is to reduce and control the pressure of fluid within the skull to minimise damage to the brain.
The main treatment is surgery to insert a shunt (long tube) that drains fluid from the brain, usually into the abdominal cavity. Sometimes it's possible to remove the obstruction to the flow of CFS. Occasionally other treatments or medication are also used.
Untreated hydrocephalus has a high mortality (50 to 60 per cent) and there may be extensive brain damage.
