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

    Författare :Nina Andersson; Anders Eklund; Karin Wårdell; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Författare :Sara Qvarlander; Anders Eklund; Jan Malm; Richard Birgander; Martin U Schuhmann; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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). LÄS MER

  4. 3. Cerebrospinal fluid studies of bipolar disorder

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

    Sammanfattning : The pathophysiology of bipolar disorder remains to be elucidated. One approach to studying brain processes is analysis of cerebrospinal fluid (CSF). LÄS MER

  5. 4. Search for Biomarkers in ALS and Parkinson's Disease : Positron Emission Tomography and Cerebrospinal Fluid Studies

    Författare :Anders Johansson; Håkan Askmark; Lennart Persson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amyotrophic lateral sclerosis; ALS; Parkinson’s disease; cerebrospinal fluid; positron emission tomography; vascular endothelial growth factor; fibroblast growth factor 2; proteomics; Fourier transform ion cyclotron resonance mass spectrometry; deprenyl-D2; PIB; FDG; L-[β11C]-DOPA; Neurology; Neurologi; Neurology; neurologi;

    Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER

  7. 5. On cerebrospinal fluid markers of HIV-1 infection

    Författare :Lars-Magnus Andersson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HIV-1; cerebrospinal fluid; AIDS dementia complex; ganglioside GD3; Tau proteins; neopterin; HIV-1 RNA; blood-brain barrier; albumin ratio; cultivation;

    Sammanfattning : HIV-1 infects the central nervous system early in the course of infection and neurological complications are common in HIV-1-infected individuals. Approximately 20% of individuals with acquired immunodeficiency syndrome (AIDS) not treated with antiretroviral therapy develop a subcortical dementia, AIDS dementia complex (ADC). LÄS MER
