Hydrocephalus in Children, Symptoms and Causes

Hydrocephalus is a condition in which there is excessive fluid in and around the brain. It occurs from a lack of absorption, blockage of flow or overproduction of the cerebral spinal fluid (CSF) that is made inside the ventricles (fluid-filled areas) of the brain and disperses from the ventricles around the brain and spinal cord. This may result in a build-up of fluid that can cause the pressure inside of the head to increase. In a child, this causes the bones of the skull to expand and separate to a larger-than-normal appearance.
