Per Kristian Eide

Per Kristian Eide is an Adjunct Professor in the Department of Neurosurgery at the University of Oslo's Faculty of Medicine, affiliated with the Institute of Clinical Medicine. His work focuses on neurosurgical research, particularly cerebrospinal fluid (CSF) dynamics, glymphatic system function, hydrocephalus, and neurological disorders such as Chiari malformation and idiopathic intracranial hypertension. His research integrates clinical neurosurgery with advanced imaging techniques like MRI to study CSF flow and molecular clearance mechanisms.

He has contributed to studies on CSF tracer dynamics, glymphatic MRI, and the role of sleep deprivation in brain fluid dynamics. His research groups include the K.G. Jebsen Centre for Brain Fluid Research and Neurovascular & Cerebrospinal Fluid Research Group. Notable collaborations involve investigating genetic risk factors for normal pressure hydrocephalus and developing imaging biomarkers for CSF disorders. His clinical expertise includes surgical and non-invasive management of CSF-related conditions, with particular attention to pediatric neurosurgery and outcomes in craniosynostosis cases.

Publications emphasize translational research linking basic CSF biology to clinical applications, including diagnostic markers for hydrocephalus and therapeutic strategies for glymphatic dysfunction. His work also addresses neurovascular interfaces, lymphatic pathways, and the pathophysiology of brain sagging dementia.
