1. 21. Clinical Consequences of Axonal Injury in Traumatic Brain Injury

   Författare :Sami Abu Hamdeh; Niklas Marklund; Per Enblad; Lars Hillered; Andreas PhD Unterberg MD; Uppsala universitet; []
   Nyckelord :Traumatic brain injury; diffuse axonal injury; intracranial pressure; magnetic resonance imaging; amyloid-beta; tau; Neurokirurgi; Neurosurgery;

   Sammanfattning : Traumatic brain injury (TBI), mainly caused by road-traffic accidents and falls, is a leading cause of mortality. Survivors often display debilitating motor, sensory and cognitive symptoms, leading to reduced quality of life and a profound economic burden to society. LÄS MER

3. 22. Finite Element and Neuroimaging Techniques toImprove Decision-Making in Clinical Neuroscience

   Författare :Xiaogai Li; Svein Kleiven; Hans von Holst; Bernhard A Schrefler; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traumatic brain injury; Intracranial Pressure; Brain edema; Gravitational force; Finite Element Model; Poroelastic parameter; Decompressive craniotomy; Image registration; Water content; Strain level; Diffusion Weighted Imaging;

   Sammanfattning : Our brain, perhaps the most sophisticated and mysterious part of the human body, to some extent, determines who we are. However, it’s a vulnerable organ. When subjected to an impact, such as a traffic accident or sport, it may lead to traumatic brain injury (TBI) which can have devastating effects for those who suffer the injury. LÄS MER

4. 23. Severe Head Injury. Evaluation of Acute Treatment and Rehabilitation

   Författare :Christer Eker; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; neuropsykologi; neurofysiologi; cerebral blood flow; neuropsychological test; assessment of motor and process skills; rehabilitation; Neurology; neuropsychology; neurophysiology; intracranial pressure; Severe head injury; intensive care;

   Sammanfattning : Mortality after severe head injury can be considerably reduce with a therapy using physiological principles for brain volume regulation and preserved microcirculation, with the main purpose of restricting the rise in ICP to reasonable levels simultaneously with preservation of adequate blood supply. This study shows that the ?Lund Concept? can reduce mortality in patients with severe traumatic brain lesions from 47% to 8%. LÄS MER

5. 24. Cerebral circulation and the sympathetic nervous system in patients with traumatic brain injury or subarachnoid hemorrhage

   Författare :Silvana Naredi; Göteborgs universitet; []
   Nyckelord :traumatic brain injury; brain edema; microcirculation; intracranial pressure; epo-prostenol; norepinephrine; subarachnoid hemorrhage; sympathetic nervous system; clonidine;

   Sammanfattning : Maintenance of adequate cerebral microcirculation is necessary to avoid cerebral ischemia after severe traumatic brain injury and non-traumatic subarachnoid hemorrhage. After severe traumatic brain injury the blood-brain-barrier is disrupted and transcapillary leakage will contribute to the development of vasogenic brain edema. LÄS MER

7. 25. The neuropsychology of idiopathic normal pressure hydrocephalus

   Författare :Per Hellström; Göteborgs universitet; []
   Nyckelord :Idiopathic normal pressure hydrocephalus; Neuropsychology; Prospective study; Shunt treatment; Treatment outcome; iNPH scale;

   Sammanfattning : Idiopathic normal pressure hydrocephalus (iNPH) is characterised by an active distension of the cerebral ventricles due to inadequate absorption of cerebrospinal fluid (CSF) into the systemic circulation. The intracranial pressure is within normal limits, the passages between the ventricles and subarachnoid spaces are open, and there is an absence of identifiable antecedents known to reduce CSF absorption.
