Head of NHRG

Per Kristian Eide received his MD from Faculty of Medicine, University of Bergen in 1989, and the same year his PhD in Neurophysiology from the Department of Physiology, Faculty of Medicine, University of Bergen, Bergen, Norway. He is a professor of clinical neurosurgery, Faculty of Medicine, University of Oslo, and senior consultant neurosurgeon/section chief (hydrocephalus) at the Department of Neurosurgery, Oslo University Hospital – Rikshospitalet. Eide’s current research involves several areas: (1) Pathophysiology of hydrocephalus and other diseases with imbalance in brain water homeostasis (idiopathic intracranial hypertension, cysts, Chiari malformation etc.) (2) Physiological monitoring of patients with brain disease/injury regarding (intracranial pressure, arterial blood pressure, intracranial compliance, cerebral auto-regulation, and non-invasive ICP monitoring). (3) Monitoring and treatment of patients with subarachnoid hemorrhage. His current main clinical activities are shunt/endoscopic surgery for hydrocephalus and other cerebrospinal fluid (CSF ) circulation disorders (idiopathic intracranial hypertension, normal pressure hydrocephalus, Chiari malformation), cerebrovascular surgery (cerebral aneurysms, cerebal vascular malformations), microvascular decompressions (trigeminal neuralgia, hemifacial spasms, glossopharyngeal neuralgia, vertigo), and surgery for brain tumors (posterior skull base, ventricular).
