Causes of hydrocephalus

Diagnosing hydrocephalus
The different types of hydrocephalus (fluid on the brain) can be diagnosed with brain scans.
Treating hydrocephalus
Both congenital and acquired hydrocephalus usually require surgery in order to reduce the pressure on the brain.
Complications of hydrocephalus
Hydrocephalus (fluid on the brain) can cause some complications, or complications may develop as a result of the surgery used to treat it.
