Pathogenesis of raised cerebrospinal fluid pressure.
Raised cerebrospinal fluid pressure may be caused by (a) subarachnoid CSF circulation blocks (b) obstruction of CSF absorption in the arachnoid villi (c) disorders of the venous return from the superior sagittal sinus to the heart. The common factor in these mechanisms is obstructed CSF drainage. Some clinical conditions illustrating these principles are reviewed.
