    Författare :Francesco Latini; Mats Ryttlefors; Lorenzo Bello; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; White matter; Cerebral gliomas; DTI; Brain-Grid; Brain mapping; Human connectome project; Anatomi; Human Anatomy; Oncology; Onkologi; Neurokirurgi; Neurosurgery; Radiology; Radiologi; Neurology; Neurologi;

    Sammanfattning : Diffuse gliomas are extremely heterogeneous tumours characterized by slow growth but extensive infiltration. Their kinetic features reflect the complex interaction over time with the surrounding brain, influencing treatment planning and outcome. LÄS MER

  3. 22. Traumatic brain injury in elderly patients

    Författare :Samuel Lenell; Per Enblad; Anders Lewén; Alfonso Lagares; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic brain injury; Elderly; Outcome; Standardized neurosurgical intensive care; Quality register; Prognostic factors; Secondary insults; Neurointensive care monitoring; Pressure reactivity index; Optimal cerebral perfusion pressure; Cerebral autoregulation; Neurokirurgi; Neurosurgery;

    Sammanfattning : The increase of elderly traumatic brain injury (TBI) patients constitutes a considerable challenge. The aim was therefore to specifically study elderly TBI patients with respect to patient characteristics, neurointensive care (NIC) and outcome, and to identify age specific features, which may be important for selection of patients and optimization of NIC in the elderly.

    Sammanfattning : Traumatic brain injury is a major cause of death and disability in the Western world. especially in young people. Understanding the pathophysiology of traumatic brain injury is the basis for further development of better therapeutic strategies for such patients. LÄS MER

  5. 24. Subarachnoid haemorrhage : clinical and epidemiological studies

    Författare :Cecilia Lindgren; Silvana Naredi; Magnus Hultin; Lars-Owe Koskinen; Elisabeth Ronne-Engström; Umeå universitet; []

    Sammanfattning : Background: Subarachnoid haemorrhage (SAH) is a severe stroke that in 85% of all cases is caused by the rupture of a cerebral aneurysm. The median age at onset is 50-55 years and the overall mortality is approximately 45%.Sufficient cortisol levels are important for survival. LÄS MER

  7. 25. Cellular and Molecular Responses to Traumatic Brain Injury

    Författare :Camilla Lööv; Anna Erlandsson; M. Elly Hol; Uppsala universitet; []

    Sammanfattning : Traumatic brain injury (TBI) is a relatively unknown disease considering the tens of millions of people affected around the world each year. Many TBI patients die from their injuries and survivors often suffer from life-long disabilities. LÄS MER
