Water on the brain

The goal of treatment is to reduce or prevent brain damage by improving the flow of CSF.

The blockage may be surgically removed, if possible. If the blockage cannot be removed, a shunt (flexible tube) may be placed within the brain to allow CSF to flow around the blocked area. The shunt tubing travels to another part of the body, such as the abdomen, where the extra CSF can be absorbed.

Antibiotics are given if there are signs of infection. Severe infections may require the shunt to be removed.

Another option is endoscopic third ventriculostomy (ETV), which relieves pressure without replacing the shunt.

Removing or burning away (cauterizing) the parts of the brain that produce CSF may reduce CSF production.

Follow-up examinations generally continue throughout the child's life. These are done to check the child's developmental level and to treat any intellectual, neurological, or physical problems.

Visiting nurses, social services, support groups, and local agencies can provide emotional support and assist with the care of a child with hydrocephalus who has significant brain damage.

Untreated hydrocephalus has a 50 - 60% death rate, with the survivors having varying degrees of intellectual, physical, and neurological disabilities.

The outlook for treated hydrocephalus depends on the cause. Hydrocephalus that is caused by disorders not associated with infection has the best outlook. Persons with hydrocephalus caused by tumors usually do very poorly.

Most children with hydrocephalus that survive for 1 year will have a fairly normal life span. Approximately a third will have normal intellectual function, but neurological difficulties may persist.

The shunt may become blocked. Symptoms of such a blockage include headache and vomiting. Surgeons may be able to help the shunt open without having to replace it.

There may be other problems with the shunt, such as kinking, tube separation, or infection in the area of the shunt.
