CSF is a clear, colorless liquid fills the cavities of the brain and the spinal cord, surrounding them and acts as a lubricant and a mechanical barrier against shock.. . CSF has a slightly alkaline chemical composition, similar to blood. It contains no red blood cells, and low amounts of protein and lipids in comparison to blood. It is about 99 percent water. There are about 100 to 150 milliliters of cerebrospinal fluid in the normal adult body.. .. . Cerebrospinal fluid is constantly produced to protect the brain and spinal cord. . . If there is a blockage, the fluid accumulates and causes swelling and pressure against the brain tissue hydrocephalus will be the consequence of this. . Day 3. Meninges.

PCR method has demonstrated that 50-70% of human meningoencephalitides are caused by CNS viral infections..

Also includes material on differential diagnosis, AIDS, neuro-oncology, psychiatric disorders, and the composition and clinical examination of cerebrospinal fluid, including a detailed discussion on the treatment of complications of the lumbar puncture.
