  2. 11. Cellular Reactions and Behavioral Changes in Focal and Diffuse Traumatic Brain Injury : A Study in the Rat and Mouse

    Author : Sara Ekmark Lewén; Lars Hillered; Niklas Marklund; Anders Lewén; Mårten Risling; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Astrocytes; Inflammatory response; Multivariate concentric square field test; Morris water maze; Exploratory behavior; Risk taking; Functional outcome.; Neurosurgery; Neurokirurgi;

    Abstract : Traumatic brain injury (TBI) is a severe condition and a major cause of death and disability. There is no pharmacological treatment available in clinical practice today and knowledge of brain injury mechanisms is of importance for development of neuroprotective drugs. READ MORE

  4. 12. Clinical Bedside Studies of Cerebral Blood Flow in Severe Subarachnoid Hemorrhage Using Xenon CT

    Author : Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Subarachnoid hemorrhage; delayed cerebral ischemia; cerebral blood flow; HHH-therapy; triple-H; xenon CT; XeCT; cerebral microdialysis; Neurokirurgi; Neurosurgery;

    Abstract : Aneurysmal subarachnoid hemorrhage (SAH) is frequently complicated by delayed cerebral ischemia (DCI), contributing to poor outcome. Particularly for patients in poor neurological state, prediction of the acute clinical course is difficult, as is the early detection of DCI. READ MORE

  5. 13. Oligodendrocyte pathology following Traumatic Brain Injury : Experimental and clinical studies

    Author : Johanna Flygt; Niklas Marklund; Fredrik Piehl; Uppsala universitet; []
    Keywords : Traumatic brain injury; oligodendrocytes; oligodendrocyte progenitor cells; interleukin 1-β; central fluid percussion injury; Neurokirurgi; Neurosurgery; Neurokirurgi; Neurosurgery;

    Abstract : Traumatic brain injury (TBI) caused by traffic and fall accidents, sports-related injuries and violence commonly results in life-changing disabilities. Cognitive impairments following TBI may be due to disruption of axons, stretched by the acceleration/deceleration forces of the initial impact, and their surrounding myelin in neuronal networks.

  6. 14. Cerebral ischemia studied with positron emission tomography and microdialysis

    Author : Peter Frykholm; Peter Kirkpatrick; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Cerebral ischemia; penumbra; positron emission tomography; microdialysis; middle cerebral artery occlusion; Neurovetenskap; Neurology; Neurologi; Neurosurgery; neurokirurgi;

    Abstract : Stroke is the third leading cause of morbidity and mortality in the industrialized world. Subarachnoid hemorrhage (SAH), the least common form of stroke, is one of the most demanding diseases treated in neurointensive care units. Cerebral ischemia may develop rapidly, and has a major influence on outcome. READ MORE

  7. 15. Deep brain stimulation of the posterior subthalamic area in the treatment of movement disorders

    Author : Anders Fytagoridis; Patric Blomstedt; Joachim Krauss; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; Movement disorders; Posterior subthalamic area; Zona incerta; Prelemniscal radiations; Tremor; Essential tremor; Parkinson s disease; neurokirurgi; Neurosurgery;

    Abstract : Background: The posterior subthalamic area (PSA) is essentially composed of the caudal Zona incerta and the prelemniscal radiation. Subthalamotomy in the PSA was renowned for its effectiveness in alleviating movement disorders and particularly tremor. READ MORE
