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.
Cerebrospinal Fluid (or CSF) is the liquid that coats and moisturizes the brain and spinal column, keeping all neurological activity and communication moving smoothly. It also protects the brain and spine from damage by acting as a shock absorber. Finding a high level of proteins in this fluid is a sign that you may have Multiple Sclerosis.
