In cases of normal pressure hydrocephalus (NPH), the build-up of CSF can be gradual and the symptoms of hydrocephalus might develop slowly over long periods of time (months and years rather than weeks). People would not necessarily experience all of these symptoms, but they would usually experience more than one of them. urinary incontinence (a loss of control passing urine).problems with vision (for example, blurred or double vision)Īdults with hydrocephalus might also experience:.The main functions of CSF are to protect the brain (it acts as a shock absorber), to carry nutrients to the brain and remove waste from it. It flows around the brain and spine, through the space between the brain’s membranes, and is then absorbed into the bloodstream. We produce almost a pint (500ml) a day in the ventricles (cavities) of our brains. It contains glucose and is slightly thicker than water. People with NPH experience a build-up of CSF in their brains without necessarily experiencing a significant increase in pressure.Ĭerebrospinal fluid (CSF) is a clear, colourless fluid that surrounds the brain and spine. There are two main forms of hydrocephalus in adults: acquired hydrocephalus and normal pressure hydrocephalus (NPH). However, the excess fluid is cerebrospinal fluid (CSF), not water. In the past, hydrocephalus was sometimes referred to as ‘water on the brain’ (the word hydrocephalus comes from the Greek words for water and head). The excess fluid leads to increased pressure on the brain which can cause damage to the brain tissue. Hydrocephalus is a build-up of fluid in the brain.
