What are possible complications of hydrocephalus?

Hydrocephalus complications include brain damage, seizures, infection, nerve damage, and impaired growth. Many of the complications, like nerve damage, seizure and impaired growth, arise due to the pressure that is being placed on parts of your brain by the excess fluid. Other complications come from surgical treatments. Surgery to remove the blockage, attempt to decrease cerebrospinal fluid, or put in a shunt for drainage can lead to infection, severe headache and brain damage.
