2. 11. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients

   Author : Johanna Mårtensson; Elna-Marie Larsson; Jimmy Lätt; Danielle van Westen; Tim Dyrby; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic Resonance Imaging; Diffusion Tensor Imaging; Tractography; white matter tracts; Radiology; Radiologi;

   Abstract : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. READ MORE

4. 12. Pathophysiological Mechanisms and Diagnostic Markers in Alzheimer’s Disease

   Author : Joakim Hertze; Klinisk minnesforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; mild cognitive impairment; white matter lesions; brain reserve; blood-brain barrier; angiogenesis; neuroinflammation; neurogranin; YKL-40; VEGF; IGF; ICAM-1; VCAM-1;

   Abstract : Alzheimer’s disease (AD), the most common cause of dementia, is a growing concern. As the life expectancy increases across the globe, the number of affected people is estimated to reach 100 million by 2050. READ MORE

5. 13. 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

6. 14. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors

   Author : Robin Pedersen; Alireza Salami; Anna Rieckmann; Anders Wåhlin; Lars Nyberg; Roser Sala-Llonch; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain architecture; functional connectivity; dopamine; aging; cognition; memory; functional magnetic resonance imaging; positron emission tomography; graph theory; Laplacian eigenmapping; gradient;

   Abstract : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. READ MORE

7. 15. Movement performance in elderly women. Relation to neuroimaging findings, medical conditions and activities of daily living

   Author : Xinxin Guo; Göteborgs universitet; []
   Keywords : movement performance; elderly women; PLM test; age; cerebral white matter lesions; brain atrophy; obesity indices; serum lipids; medical conditions and IADL.;

   Abstract : Aims: To study age-related changes of movement performance and their relation to cerebral white matter lesions, brain atrophy, obesity indices, serum lipids, medical conditions and instrumental activities of daily living (IADL).Methods: Study samples were part of the Prospective Population Study of Women and the Gerontological and Geriatric Population Studies (H 70) in Göteborg, Sweden.
