  1. 1. Hypertension, blood pressure, cognition and cerebral blood flow in the cohort of "Men born 1914"

    Författare :Faina Reinprecht; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; samhällsmedicin; Social medicine; Socialmedicin; Gerontologi; Gerontology; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; regional cerebral blood flow; cohort study; Neurology; neuropsychology; blood pressure; blood pressure monitoring; risk factors; Hypertension;

    Sammanfattning : "Men born 1914" is a population based cohort study of the epidemiology of cardiovascular disease. Five hundred men, born 1914, were examined at the age of 68 and 185 of them were re-examined at 81 years of age. LÄS MER

  3. 2. Cerebral blood flow and intracranial pulsatility studied with MRI : measurement, physiological and pathophysiological aspects

    Författare :Anders Wåhlin; Anders Eklund; Jan Malm; Richard Birgander; William G Bradley; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arterial Pulsatility; cerebrospinal fluid; cerebral blood flow; venous flow; intracranial pressure; pulse pressure; dementia; hippocampus; multiple sclerosis; magnetic resonance imaging; radiofysik; radiation physics;

    Sammanfattning : During each cardiac cycle pulsatile arterial blood inflates the vascular bed of the brain, forcing cerebrospinal fluid (CSF) and venous blood out of the cranium. Excessive arterial pulsatility may be part of a harmful mechanism causing cognitive decline among elderly. LÄS MER

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

    Författare :Henrik Engquist; Per Enblad; Elham Rostami; Anders Lewén; Marianne Juhler; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Cerebral Blood Flow and Cognition. Clinical studies on Dementia and Cognitive Decline

    Författare :Arkadiusz Siennicki-Lantz; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gerontology; Gerontologi; vascular risk factors; carotid ultrasound; peripheral arterial disease; orthostatic hypotension; blood pressure; ageing; SPECT; cerebral blood flow; cognition; Dementia; Alzheimer’s disease;

    Sammanfattning : The importance of early detection of brain changes during ageing has been recognised. Single photon emission computed tomography (SPECT) is a method used for estimation of cerebral blood flow (CBF) in clinical work and in research. LÄS MER

  7. 5. Detection and haemodilutive treatment of cerebral arterial vasospasm and delayed ischaemia after Aneurysmal Subarachnoid Haemorrhage

    Författare :Anders Ekelund; Neurokirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral oxygen delivery.; cerebral blood flow; hypervolaemic haemodilution; isovolaemic haemodilution; transcranial cerebral oximetry; transcranial Doppler ultrasound; delayed ischaemic deficit; Aneurysmal subarachnoid haemorrhage; cerebral arterial vasospasm; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : This thesis deals with cerebral arterial vasospasm and ischaemia, a serious complication after aneurysmal subarachnoid haemorrhage. Firstly is the noninvasive transcranial Doppler ultrasound and transcranial cerebral oximetry techniques evaluated in detecting cerebral arterial vasospasm in clinical practice. LÄS MER
