Abnormal buildup of cerebrospinal fluid (CSF) in the brain, which can result in brain damage or death, is called hydrocephalus. Read the article to know more.

What Causes Hydrocephalus? & Treatments

The brain has two circulations.

Functions of CSF

However if CSF collects in excess and is not reabsorbed, then pressure inside the skull can increase to damage brain cells or even kill them by depriving them of oxygen and glucose.

Causes of Hydrocephalus

Two Main Forms of Hydrocephalus

After the age of 2 years, the skull bone plates join together so that the head can no longer enlarge in response to CSF accumulation. Subsequently, the pressure inside the skull, called intracranial pressure (ICP), increases and thus reduces the blood flow to the brain as well as causing physical changes to the brain. Deformity of the nerves from increased pressure causes loss of vision, difficulty in thinking, difficulty with coordination and loss of memory. If unchecked it can lead to shifts of brain structures, called herniations, which can result in permanent coma or death.

If the pressure remains above that which allows blood flow into the brain for even a few minutes, then a condition where the brain essentially dies, called brain death, will occur.

Treatment for Hydrocephalus

There are thousands of people around the world living independent and useful lives following successful surgery for hydrocephalus.
