The term hydrocephalus is derived from the Greek words "hydro" meaning water and "cephalus" meaning head. So it is a brain condition that happens when cerebrospinal fluid (CSF) can't drain from the brain and causes a buildup of fluid in the skull. CSF is the clear, watery fluid that surrounds and cushions the brain and spinal cord. The excessive accumulation of CSF results in an abnormal widening of spaces in the brain called ventricles. This widening creates potentially harmful pressure on the tissues of the brain and cause a range of impairments in brain function. Hydrocephalus can happen at any age, but it occurs more frequently among infants and adults 60 and over.
Causes
Hydrocephalus can be congenital or acquired:
  • Congenital hydrocephalus means a baby is born with the condition. This is often due to problems like spina bifida (abnormal development of the spinal cord) or aqueductal stenosis (the narrowing of a small passageway connecting two major ventricles in the brain).
  • Acquired hydrocephalus happens after birth and can affect people of any age. It's usually caused by bleeding in the brain. however, the cause is sometimes unknown.
Risk factors
Risk Factors for Newborns Congenital hydrocephalus may occur because of any of the following:
  • Abnormal development of the central nervous system
  • Bleeding within the ventricles
  • Infection in the uterus during a pregnancy, such as rubella or syphilis, that can cause inflammation in fetal brain tissues
Risk Factors for Other Age Groups  A number of developmental or medical problems can contribute to or trigger hydrocephalus. They may include:
  • Lesions or tumors of the brain or spinal cord
  • Central nervous system infections, such as bacterial meningitis or mumps
  • Bleeding in the brain from a stroke or head injury
  • Other traumatic injury to the brain
