Hydrocephalus is a condition characterized by excessive accumulation of cerebrospinal fluid (CSF) in the brain. The ventricles, which are spaces in the brain, begin to enlarge abnormally due to excess fluid. Enlargement of the ventricles can cause harmful pressure on brain tissue. Normally, CSF flows freely through the ventricles of the brain, coats the brain and spinal cord, and is reabsorbed into the bloodstream. This fluid is constantly produced, so the balance between production and absorption is essential for the body. Anything that disrupts the absorption or normal flow of CSF will result in an unhealthy excess. The pressure caused by an overabundance of CSF against the brain tissue causes hydrocephalus. Hydrocephalus can be divided into different types. Congenital hydrocephalus is the result of genetic abnormalities or various influences during fetal development. Acquired hydrocephalus develops at birth or sometime later in life and is usually the result of injury or illness. Communicating hydrocephalus occurs when the flow of CSF is blocked after leaving the ventricles, a...
