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

    Author : Anders Wåhlin; Anders Eklund; Jan Malm; Richard Birgander; William G Bradley; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. 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. 3. Cerebral Blood Flow and Cognition. Clinical studies on Dementia and Cognitive Decline

    Author : Arkadiusz Siennicki-Lantz; Geriatrik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Studies of cerebral blood flow and cerebrospinal fluid in childhood acute lymphoblastic leukemia

    Author : Gustaf Österlundh; Göteborgs universitet; []
    Keywords : childhood acute lymphoblastic leukemia; methotrexate; neurotoxicity; cerebral blood flow; single photon emission computed tomography; cerebrospinal fluid; neuron-specific enolase; glia fibrillary acidic protein; neurofilament; ascorbyl radical;

    Abstract : Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and more than 80% of the patients are cured today. Treatment might cause side effects and central nervous system (CNS) irradiation has been replaced by systemic high-dose methotrexate (MTX) and intrathecal (IT) MTX due to the risk of late effects.

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

    Author : Faina Reinprecht; Geriatrik; []
    Keywords : 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;

    Abstract : "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. READ MORE
