cerebrospinal fluid stroke volume

Intracranial pressure dynamics are not linked to aqueductal cerebrospinal fluid stoke volume

Authors: Tain RW, Alperin N.

TO THE EDITOR: A recent study by Hamilton et al. (4) proposes that aqueductal cerebrospinal fluid (CSF) stroke volume (ASV) is significantly associated with the width of the second peak of the intracranial pressure (ICP) waveform in normal pressure hydrocephalus. Existing evidence and current understanding of ICP physiology do not support a mechanistic link between aqueductal CSF flow and ICP dynamics.
