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 grow abnormally due to excess fluid. Enlargement of the ventricles can cause harmful pressure on brain tissues. Normally, cerebrospinal fluid 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 normal absorption or flow of cerebrospinal fluid will cause an unhealthy surplus. Pressure caused by an overabundance of cerebrospinal fluid against the brain tissue causes hydrocephalus. Hydrocephalus can be divided into several types. Congenital hydrocephalus is the result of genetic abnormalities or various factors during the development of the fetus. Acquired hydrocephalus develops at birth or later in life and is usually the result of an injury or disease. Communicating hydrocephalus occurs when the flow of cerebrospinal fluid is blocked after leaving the ventricles, a...
