About This Condition
Hydrocephalus is an abnormal build-up of cerebrospinal flush (CSF) in the ventricles deep within the brain. This excess CSF cause the ventricles to widen which puts pressure on the brain's tissues, squashing them. Acquired hydrocephalus develops over time due to injury or disease. Brain or spinal cord tumours, central nervous system infections such as bacterial meningitis or bleeding in the brain due to injury or stroke can all increase the risk of developing hydrocephalus as any age.
