B-waves in noninvasive capacitance signal correlate with B-waves in ICP
The concurrent presence of B-waves in the signals suggests that vasogenic activity of cerebral autoregulation is reflected in W. The weaker correlation of amplitudes may be attributed to W being an indirect measure of cranial volume composition, whereas ICP is a measure of pressure, with the two linked by the non-linear craniospinal pressure-volume relation that varies between patients. Analysis of the noninvasively acquired W signal should be evaluated as a triage tool for patients with NPH and other disorders characterized by reduced compliance.
