Chapter 10 - Hydrocephalus

Summary

Definition: A disturbance of cerebral spinal fluid formation, flow or absorption resulting in enlarged cerebral spinal fluid compartment within the central nervous system.

Communicating hydrocephalus: Hydrocephalus with full communication between the ventricular system and the subarachnoid space. It is usually caused by ineffective CSF absorption or excess CSF production.

Non-communicating hydrocephalus: Hydrocephalus results from an obstruction of CSF flow within the path of the ventricular system or its outlets.

Normal pressure hydrocephalus: Hydrocephalus occurring in predominantly elderly patients who exhibit normal intracranial pressure, in spite of increased CSF compartment size.
