All About Hydrocephalus

Hydrocephalus is an abnormality of the normal dynamics of the cerebrospinal fluid (CSF). The CSF is a water-like fluid that surrounds the brain and spinal cord. Normally, it is produced, flows throughout the open spaces in and around the central nervous system (the ventricles and subarachnoid space) and is then re-absorbed. However, some conditions can lead to the accumulation of this fluid or other abnormalities in its flow which can damage the brain and lead to significant symptoms.

In general, hydrocephalic conditions are separated into two categories:

1. Communicating or Non-Obstructive Hydro: In patients who do not have a visible (on imaging studies) obstruction of the flow of cerebrospinal fluid.
2. Non-Communicating or Obstructive Hydro: In patients who do have a visible obstruction of the flow of cerebrospinal fluid.

Below you will find a list of types of CSF abnormalities with links to more information about each:

• Adult Hydro
• Pediatric (Congenital) Hydro
• Normal Pressure Hydro (NPH)
• Aqueductal Stenosis
• Tumor-Associated Hydro
• Pseudotumor Cerebri

Learn about the surgical procedures which are commonly used to treat various forms of hydro:

• Hydro Shunt Procedures: A shunt is the most common treatment for these diseases. Learn more about what it is and how it works here.
• Endoscopic Third Ventriculostomy: A newer treatment, ETV is an excellent treatment for some specific types of these disorders.
