  1. 1. Magnetic resonance imaging markers of cerebral small vessel disease in an elderly population – association with cardiovascular disease and cognitive function

    Författare :Ruta Nylander; Elna-Marie Larsson; Mona K. Beyer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; cerebral perfusion; small vessel disease; cognitive function; Radiology; Radiologi;

    Sammanfattning : Cerebral small vessel disease (SVD) is identifiable by clinical, neuroimaging, neuropathological and cognitive findings.The aim of this thesis was to assess SVD and cerebral perfusion on magnetic resonance imaging (MRI) in a 75-year-old population and compare the findings with scars of myocardial infarctions, cardiovascular risk markers and cognitive function.

  3. 2. Atrial fibrillation in aging; methodological aspects and the relation to dementia and cerebral vascular disease

    Författare :Lina Rydén; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; dementia; stroke; silent brain infarcts; white matter hyperintensity; cerebral microbleed; small vessel disease; epidemiology;

    Sammanfattning : Emerging evidence suggest an increased risk of dementia in individuals with atrial fibrillation (AF). However, until recently, few studies have investigated the relation between AF and dementia taking both prevalent and incident stroke into account. LÄS MER

  4. 3. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging

    Författare :Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

  5. 4. CADASIL : a pure model for studying cerebral small vessel disease

    Författare :Mahmod Panahi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL) is caused by a mutation on the NOTCH3 gene. The pathological driver behind this disease is the loss of vascular smooth muscle cells (VSMCs) in small blood vessels and subsequent fibrotic thickening of the vessel, causing stenosis. LÄS MER
