1. 11. Physical Modeling of Brain and Head Kinematics

   Författare :Johan Ivarsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

   Sammanfattning : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. LÄS MER

3. 12. Offenders with mental disorder : psychosocial and neurobiological aspects

   Författare :Katarina Howner; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The main hypothesis of this thesis is that certain functions, or symptoms, in mentally disordered offenders are connected to biological correlates. There is no specific diagnosis that explains antisocial or violent behaviour. Among offenders some functions or symptoms are considered more common, such as impulsivity and reduced empathy. LÄS MER

4. 13. Quantitative MRI Biomarkers of Neurodegeneration in Multiple Sclerosis

   Författare :Michael Platten; Tobias Granberg; Chunliang Wang; Fredrik Piehl; Sara Shams; Mattias Vågberg; KTH; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Machine learning; Multiple sclerosis; Corpus callosum; Neurodegeneration; Medical Technology; Medicinsk teknologi;

   Sammanfattning : Background: Multiple sclerosis (MS) is a chronic neuroinflammatory and neurodegenerative disease that targets myelin in the brain and spinal cord. The corpus callosum connects the cerebral hemispheres and is composed of heavily myelinated axons. LÄS MER

5. 14. Rolandic Epilepsy : A Neuroradiological, Neuropsychological and Oromotor Study

   Författare :Staffan Lundberg; Orvar Eeg-Olofsson; Raili Raininko; Ulrich Stephani; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; rolandic epilepsy; children; idiopathic focal epilepsy; magnetic resonance imaging; proton magnetic resonance spectroscopy; cognition; neuropsychology; oromotor performance; dichotic listening; hippocampus; classification; Pediatrik; Paediatric medicine; Pediatrisk medicin;

   Sammanfattning : Rolandic epilepsy (RE) is the most common focal epilepsy syndrome in the pediatric age group with an onset between 3 and 13 years. The syndrome is defined by electro-clinically typical features and has been considered benign according to seizure remission before the age of 16 years. LÄS MER

7. 15. Post Cardiac Arrest Care : Evaluation of prognostic tools, Patient outcomes and Relatives’ experiences at 6 months after the event

   Författare :Ewa Wallin; Sten Rubertsson; Marja-Leena Kristofferzon; Silvana Naredi; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; hypothermia; neurological outcome; cerebral oxygenation; MRI; relatives; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The overall aim of the present thesis was to study post-resuscitation care of cardiac arrest (CA) patients treated with target temperature management 33°C with a focus on evaluation of two prognostic tools: variations in cerebral venous saturation and acute magnetic resonance imaging (MRI) findings on the brain post-CA. An additional aim was to investigate patients’ neurological outcome and relatives’ experiences 6 months after the event. LÄS MER
