  1. 31. Cerebral perfusion during cardiopulmonary bypass with special reference to blood flow

    Författare :Thomas Tovedal; Fredrik Lennmyr; Stefan Thelin; Dan Lindblom; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cardiopulmonary bypass (CPB) is an important method that enables open heart surgery. There is a risk of neurological complications, and efforts to minimize those include optimization of the cerebral perfusion during CPB. LÄS MER

  3. 32. Microvascular plasticity and neurovascular coupling in the pharmacotherapy of Parkinson's disease

    Författare :Elisabet Ohlin; Basala gangliernas patofysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson s disease; levodopa; dyskinesia; angiogenesis; cerebral blood flow; blood-brain barrier;

    Sammanfattning : L-DOPA pharmacotherapy in Parkinson’s disease (PD) is associated with adverse effects occurring after a few years of treatment. Among these, dyskinesia (abnormal involuntary movements) is particularly common and potentially disabling. LÄS MER

  4. 33. WAVELET NOISE REDUCTION AND VASCULAR WATER TRANSPORT MODELLING : APPLICATIONS TO DIFFUSION AND PERFUSION MRI

    Författare :Adnan Bibic; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; perfusion; diffusion; arterial spin labelling; wavelets; filtering; denoising; blood-brain barrier; permeability; Fysicumarkivet A:2018:Bibic;

    Sammanfattning : Magnetic resonance imaging (MRI) is a powerful medical imaging technique, used to detect and characterise a range of diseases and conditions. It is based on the use of a strong static magnetic field in combination with magnetic field gradients and pulsed radiofrequency electromagnetic fields to visualise various organs and structures in the body according to their morphology or function.

  5. 34. Cerebral ischemia studied with positron emission tomography and microdialysis

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

    Sammanfattning : 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. LÄS MER

  7. 35. Posture and brain function in dementia. A study with special reference to orthostatic hypotension

    Författare :Ulla Passant; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; falls and fractures.; white matter disease; hypoperfusion; frontal lobes; regional cerebral blood flow; blood pressure; orthostatic hypotension; Organic dementia; normal subjects; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik;

    Sammanfattning : Orthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. LÄS MER
