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

2. Atrial fibrillation in aging; methodological aspects and the relation to dementia and cerebral vascular disease
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
3. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging
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.

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