In some cases, hydrocephalus starts before a baby is born. The most common causes of congenital hydrocephalus are: Acquired hydrocephalus develops at any point after birth and can affect people of all ages. The body cavity in which the CSF is diverted usually is the peritoneal cavity (the area surrounding the abdominal organs). Normally, CSF flows through and out of the ventricles and protects the brain and the spinal column. Mechanisms of hydrocephalus after intraventricular haemorrhage in Many children experience lifelong brain damage after hydrocephalus. An alternative operation called endoscopic third ventriculostomy may be recommended.

Normal Pressure Hydrocephalus (NPH) can be the result of bleeding in the brain's CSF (also known as subarachnoid or intraventricular hemorrhage), head trauma, infection, tumor, or a complication of surgery. The only available treatment for hydrocephalus is the surgical implantation of a shunt, a device that channels CSF sway from the brain to another part of the body where it can be absorbed. This hole creates a pathway for the excess CSF to flow in and around the brain. Acute hydrocephalus may present with headache, nausea, vomiting, lethargy, and/or change in mental status and may progress to coma and death if untreated. These can indicate signs of excess CSF.
