There are many other disorders and conditions that can occur in addition to hydrocephalus. An example of this is epilepsy; a disorder in the central nervous system which is characterized by recurrent electrical disturbances in the brain.

Similarly, meningitis can develop; an infection that causes inflammation of the membranes that surround the brain. Symptoms may include a general feeling of ill health, nausea, abdominal pain, along with stiffness in the back and neck. Others conditions involved with hydrocephalus include hematomas, brain tumors, strokes, and dementia. There is currently no known way to prevent or cure hydrocephalus. The most common treatment for hydrocephalus is surgical implantation of a shunt. A shunt is a flexible tube placed into the ventricular system of the brain which diverts the flow of cerebrospinal fluid to another region of the body most often the abdominal cavity, where it can then be absorbed. A valve within the shunt maintains cerebrospinal fluid pressure at normal levels within the ventricles (2Hydrocephalus Association, n.d.). Shunts are s a delicate piece of…
