Reduced flow and absorption of CSF into specialized blood vessels called arachnoid villi can also result in a buildup of CSF in the ventricles and communicating hydrocephalus. This form is called communicating because the CSF can still flow between the ventricles, the passages between which remain open. The two major types of hydrocephalus are called communicating hydrocephalus and non-communicating hydrocephalus.Ĭommunicating hydrocephalus occurs when the flow of CSF is blocked after it exits the ventricles. Some of these cases can be associated with abnormalities in the brain and spinal cord during pregnancy. Hydrocephalus can affect anyone at any age but is most common in infants and older adults. Top What are the different types of hydrocephalus? (Hydrocephalus is the most common reason for brain surgery in young children.) With treatment many people lead normal and productive lives. Though treatment is often helpful, it may take multiple surgeries to treat hydrocephalus.
The pressure from too much CSF can keep the brain from functioning properly and cause brain damage and even death.įortunately, there are treatment options that can restore normal levels of CSF. However, when the normal flow or absorption of CSF is blocked it can result in a buildup of CSF. The body typically produces enough CSF each day and absorbs the same amount. Normally, cerebrospinal fluid flows through the ventricles and bathes the brain and spinal cord before being reabsorbed into the bloodstream.
This excess fluid causes the ventricles to widen, putting pressure on the brain’s tissues.Ĭerebrospinal fluid (CSF) is the clear, colorless fluid that protects and cushions the brain and spine. Hydrocephalus is an abnormal buildup of fluid in the ventricles (cavities) deep within the brain. What are the possible complications of a shunt system? What are the different types of hydrocephalus?
