A quarter of a century has elapsed since Nils Lundberg published his thesis "Continuous Recording and Control of Ventricular Fluid Pressure In Neurosurgical Practice". This publication, more than any other, propelled continuous monitoring of intracranial pressure from the status of a research tool to become an integral part of neurosurgical intensive care, with wide application in the management of patients with head injuries, intracranial haemorrhage, brain tumours and disorders of the CSF circulation. At the same time, experimental studies by Langfitt and others stimulated investigations of the relationships between intracranial pressure and cerebral blood flow, intracranial pressure volume relationships and studies of the formation and absorption of CSF. By 1972, Mario Brock had realised the extent of the interest in intracranial pressure research and organised the First International Symposium on Intracranial Pressure in Hanover in that year. This was the start of a series of highly successful meetings, subsequently held in Lund (1974), Groningen (1976), Williamsburg (1979) and Tokyo (1982), the proceed ings of which have been published as a uniform series of books. In each of these volumes the up to date status of research and clinical application of intracranial pressure measurement has been presented in a concise yet comprehensive way. The present volume contains the proceedings of the Sixth International Intracranial Pressure Symposium that was held in Glasgow, Scottland, from June 9th to 13th, 1985.
