What Are the Basics of Hydrocephalus?

Q:
What are the basics of hydrocephalus?
A:
Hydrocephalus is a condition which occurs when fluid builds up in the skull. It can lead to swollen brain because the excess fluid increases the size of the ventricles and puts pressure on the brain. Hydrocephalus literally means “water in the brain”.

Causes

Hydrocephalus is mainly caused by the imbalance between how much cerebrospinal fluid (CSF) is produced and how much it is absorbed into the bloodstream.

Before a baby is born, hydrocephalus may result from:

• A birth defect in which the spinal column doesn’t close
• a genetic abnormality
• Rubella occurring during pregnancy

After the baby is born, hydrocephalus can be caused by the followings:

• Head trauma
• Central nervous system tumors
• Central nervous system infections like meningitis
• Bleeding in the brain, especially in babies born prematurely
