[Disorders of intracranial volume-pressure relations]

The clinical aspects of volume-pressure relations and their disturbances are presented with description of acute and chronic changes after intracranial lesions and various physiological situations. The diagnostic methods which are applied for the assessment of intracranial volume-pressure relations are discussed. A method clinically useful is the numerical analysis of CT images, which is a direct methods, while the indirect methods include computer analysis of the ICP value, lumbar infusion tests and analysis of electrophysiological studies, especially evoked potentials. Further development of studies of volume-pressure relations for diagnostic purposes is foreseen.
