What is a shunt?
A shunt is a hollow tube surgically placed in the brain (or occasionally in the spine) to help drain cerebrospinal fluid and redirect it to another location in the body where it can be reabsorbed.
Shunt procedures can address pressure on the brain caused by hydrocephalus and relieve its symptoms such as gait difficulty, mild dementia and lack of bladder control.
If the doctor finds that these problems improve after a lumbar puncture, it may mean that placing a shunt may be able to provide a longer-term benefit.
