2. 1. Volumetric assessment of hippocampus and cerebral white matter lesions in structural MRI

   Author : Erik Olsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; structural MRI; white matter lesions; hippocampal volumetry; reliability; mild cognitive impairment; dementia; low dose radiation;

   Abstract : Assessment in structural MRI like hippocampal volumetry and white matter lesion (WML) assessment is receiving widespread attention and recommen-dation as important research and diagnostic tools. The aim in this thesis is to contribute to enhanced reliability and validity in structural MRI assessment. READ MORE

4. 2. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

   Author : Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

   Abstract : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. READ MORE

5. 3. Epidemiological, clinical anf pathogenetic studies of acute intermittent porphyria

   Author : Ingemar Bylesjö; Christer Andersson; Pertti Mustajoki; Umeå universitet; []
   Keywords : Medicine; Acute intermittent porphyria; epilepsy; melatonin; diabetes mellitus; white-matter lesions; symptoms; Medicin; Medicine; medicin;

   Abstract : Porphyrias are inherited metabolic disorders characterised by an impairment of heme biosynthesis. Acute intermittent porphyria (AIP) is the most common of the acute porphyrias in Sweden. Acute attacks of AIP are characterised by neuro-psychiatric symptoms, including epileptic seizures. READ MORE

6. 4. Craniopharyngioma. Morbidity and Structural Changes in the Brain

   Author : Sigríður Bára Fjalldal; Lund Medicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; craniopharyngioma; hypothalamus; hypothalamic obesity; metabolism; cognition; magnetic resonance imaging; diffusion tensor imaging; white matter lesions; morbidity; cardiovascular risk; craniofaryngiom; hypotalamus; hypotalamisk fetma; ämnesomsättning; kognition; magnetkameraundersökning; vitsubstansförändringar; dödlighet; hjärt-kärlsjukdomar;

   Abstract : Hypothalamus (HT) is a brain structure which serves as a coordination center for several vital body functions. Craniopharyngioma (CP) is a pituitary tumor with high morbidity, primarily due to HT lesion. READ MORE

7. 5. Hippocampal volumetry in mild cognitive impairment

   Author : Carl Eckerström; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mild cognitive impairment; dementia; Alzheimer s disease; vascular dementia; MRI; hippocampus; white matter lesions; CFS biomarkers; neuropsychology;

   Abstract : Dementia is a syndrome with cognitive decline as a prominent feature. MCI is similarly a syndrome of cognitive decline, albeit with much subtler symptoms, and has been identified as a condition at risk for progression to dementia. A considerable clinical challenge lies in identifying MCI patients with an underlying dementia disorder. READ MORE
