Cerebrospinal Fluid Dynamics

This is a comprehensive chapter for those seeking a better understanding of the vital role of cerebrospinal fluid (CSF) in the central nervous system (CNS). This chapter covers the essential functions of CSF, including its role in the protection of the brain and spinal cord, in the maintenance of stable intracranial pressure (ICP), and in the facilitation of nutrient and hormone transport, protein and waste clearance, and CNS homeostasis. The authors provide an overview of the secretion, flow, and reabsorption of CSF and discuss the communication between the CNS, the peripheral nervous system (PNS), and the lymphatic system. This chapter also explores the existing knowledge and new theories regarding the CSF system, with a focus on controversial topics such as the glymphatic system and CNS lymphatics. In the second section, this chapter reviews changes in CSF dynamics in various neurological diseases and their relationship with intracranial pressure. This chapter provides readers with a comprehensive understanding of the critical role of CSF in CNS health and disease, enabling them to make informed decisions when diagnosing and treating patients with neurological conditions.
