The CSF alterations in these circumstances raise so many important problems that we consider it worthwhile to discuss in one chapter the mechanisms of the formation, circulation, and absorption of the CSF, particularly as they pertain to alterations of intracranial pressure (ICP). It follows that the diseases that result from perturbations in these mechanisms, namely hydrocephalus, pseudotumor cerebri, and syndromes produced by reduced pressure in the CSF compartment, are also presented. Further information on the management of raised ICP, particularly as it pertains to traumatic brain injury, can be found in Chap. 34. Examination of the CSF as a diagnostic aid in neurology was discussed in Chap. 2, and the primary infectious and noninfectious inflammatory reactions of the pia-arachnoid (leptomeninges) and ependyma of the ventricles are considered in Chap. 31.
