The term hydrocephalus is derived from
two Greek words, hydro for water and kephale for head. Hydrocephalus
implies an excessive accumulation of cerebrospinal fluid (CSF)
within the cavities, or ventricles, of the brain. Build-up in CSF
volume can result from interference with normal CSF circulation
(due to an obstruction in the brain's ventricular system), or as
the result of a problem with CSF reabsorption.
Hydrocephlus can be a congenital or an acquired condition. Congenital
hydrocephlus simply means that the condition existed before birth;
acquired hydrocephlus develops after birth, as a result of trauma,
a brain turmor, scar tissue formation, or meningitis.
Hydrocephalus is a lifelong condition in that the patient is treated
rather than cured. Treatment, by shunting the CSF to another area
of the body, generally allows patients to lead full and active
lives.
Patients and their families, however, should be aware of the signs
and symptoms of complications so that medical care can be sought
in a timely manner when necessary.
