  2. 1. Analysis of ICP pulsatility and CSF dynamics : the pulsatility curve and effects of postural changes, with implications for idiopathic normal pressure hydrocephalus

    Author : Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cerebrospinal fluid; CSF dynamics; Intracranial pressure; Pulse pressure; Normal pressure hydrocephalus; Posture; Predictive tests; Mathematical modelling; Magnetic resonance imaging; Infusion tests;

    Abstract : The volume defined by the rigid cranium is shared by the brain, blood and cerebrospinal fluid (CSF). With every heartbeat the arterial blood volume briefly increases and venous blood and CSF are forced out of the cranium, leading to pulsatility in CSF flow and intracranial pressure (ICP). READ MORE

  4. 2. Cerebrospinal fluid infusion methods : development and validation on patients with idiopathic normal pressure hydrocephalus

    Author : Nina Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Infusion test; idiopathic normal pressure hydrocephalus; outflow conductance; outflow resistance; intracranial pressure; cerebrospinal fluid dynamics; medical informatics; medicinsk informatik;

    Abstract : Cerebrospinal fluid (CSF) infusion tests can be used to estimate the dynamic properties of the CSF system. Idiopathic normal pressure hydrocephalus (INPH) is a syndrome signified by a disturbance to the CSF system, where the cause is unknown and the diagnosis is difficult to determine. READ MORE

  5. 3. Fluid dynamic principles for analysis of intracranial pressure control : application towards space medicine and hydrocephalus

    Author : Petter Holmlund; Anders Eklund; Sara Qvarlander; Jan Malm; Marek Czosnyka; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intracranial pressure; posture; cerebrospinal fluid; microgravity; venous collapse; internal jugular vein; fluid dynamics; venous pressure; spaceflight-associated neuro-ocular syndrome; hydrocephalus; mathematical modeling; ultrasound; magnetic resonance imaging;

    Abstract : Intracranial pressure (ICP) is an important component of the fluid dynamic environment of the brain and plays a central role with regards to the maintenance of normal cerebral blood flow and neuronal function. However, many regulatory mechanisms controlling the ICP are still poorly understood. READ MORE

  6. 4. Novel cerebrospinal fluid and blood tau biomarkers in Alzheimer's disease and other neurodegenerative diseases

    Author : Juan Lantero Rodriguez; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tau; Phosphorylation; Biomarkers; Alzheimer’s disease; CSF; Blood;

    Abstract : Tau is a protein predominantly expressed in neurons in the central nervous system (CNS), where it binds microtubules (MT), playing a major role regulating their dynamics and architecture. Under pathological conditions, tau detaches from MTs, leading to neuronal dysfunction and cell death. READ MORE

  7. 5. Cerebrospinal fluid studies of bipolar disorder

    Author : Anniella Isgren; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bipolar disorder; Cerebrospinal fluid; Biomarkers; Pathophysiology; Proteomics; Neuroimmunology; Cytokines;

    Abstract : The pathophysiology of bipolar disorder remains to be elucidated. One approach to studying brain processes is analysis of cerebrospinal fluid (CSF). READ MORE
