Abstract

Headache in the morning is one of the most characteristic features of chronic intracranial hypertension, and indeed an increase of intracranial pressure (ICP) has been considered to be involved during this period. However, quantitative studies on ICP and on pressure waves (PW) under these circumstances are limited. Therefore, a quantitative study on PWs was conducted, particularly with respect of the circadian rhythm in patients with brain tumors. The effect of steroids on PW as well as on the ICP baseline was analyzed in addition.
