Impaired glymphatic function in idiopathic intracranial hypertension
Eide, Per Kristian; Pripp, Are Hugo; Ringstad, Geir; Valnes, Lars Magnus (Brain Communications;Volume 3, Issue 2, Peer reviewed; Journal article, 2021-03-21)Idiopathic intracranial hypertension is a brain disease incorporating cerebrospinal fluid disturbance, increased intracranial pressure and visual failure, but with unknown cause. This study examined a hypothesis that ... -
Physiological alterations of pineal recess crowding in symptomatic non-hydrocephalic pineal cysts
Eide, Per Kristian; Lindstrøm, Erika Kristina; Pripp, Are Hugo; Valnes, Lars Magnus; Ringstad, Geir (Peer reviewed; Journal article, 2023)Pineal cysts are prevalent in the population. Due to more widespread use of magnetic resonance imaging, an increasing number of symptomatic patients with non-hydrocephalic pineal cysts are referred to neurologists and ... -
Plasma neurodegeneration biomarker concentrations associate with glymphatic and meningeal lymphatic measures in neurological disorders
Eide, Per Kristian; Lashkarivand, Aslan; Pripp, Are Hugo; Valnes, Lars Magnus; Hovd, Markus Herberg; Ringstad, Geir; Blennow, Kaj; Zetterberg, Henrik (Peer reviewed; Journal article, 2023)Clearance of neurotoxic brain proteins via cerebrospinal fluid (CSF) to blood has recently emerged to be crucial, and plasma biomarkers of neurodegen- eration were newly introduced to predict neurological disease. This ... -
Prospective T1 mapping to assess gadolinium retention in brain after intrathecal gadobutrol
Ringstad, Geir; Valnes, Lars Magnus; Vatnehol, Svein Are Sirirud; Pripp, Are Hugo; Eide, Per Kristian (Peer reviewed; Journal article, 2023)Purpose A possible pathway behind gadolinium retention in brain is leakage of contrast agents from blood to cerebrospi- nal fluid and entry into brain along perivascular (glymphatic) pathways. The object of this study was ...
