Cerebrospinal fluid (CSF), a clear, colorless fluid produced in the brain, contains glucose, proteins, and other substances also found in the blood. CSF surrounds the brain and spinal cord, serving as a cushion for the brain in the skull.
Causes of Extra Fluid in the Brain. Extra fluid on the brain is a condition known as hydrocephalus. The fluid is actually cerebral spinal fluid, or CSF, that surrounds the brain and spinal cord. When there is an excess of CSF in the brain spaces, or ventricles, this causes the ventricles to widen and can lead to excessive pressure on brain tissue.
