  1. 1. Cerebral white matter changes in patients with cognitive impairment - clinical and pathophysiological aspects

    Author : Michael Jonsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; white matter changes; vascular factors; cognitive impairment; neuropsychiatric symptoms; cerebrospinal fluid biomarkers; demyelination; axonal degeneration;

    Abstract : Cerebral white matter changes (WMC), detected with computed tomography (CT) or magnetic resonance imaging (MRI), represent a common condition in elderly people. However, the prognostic, symptomatological and biochemical constituents of WMC are only partially known. READ MORE

    Abstract : Alzheimer's disease (AD) is the most prevalent type of dementing disorder. The cortical pathology of AD has been recognized for almost a century. In later years, an associated pathological feature of AD has been identified which affects the white matter. READ MORE

  3. 3. The matter of white and gray matter in cognitive impairment

    Author : Soheil Damangir; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Cognitive impairment spans from minor subjective cognitive impairment to disabling dementia. Many biomarkers have been developed to monitor different aspects of cognitive impairment. Magnetic resonance imaging is the most used neuroimaging biomarker in research and can measure gray matter (GM) and white matter (WM) changes. READ MORE

  4. 4. Craniopharyngioma. Morbidity and Structural Changes in the Brain

    Abstract : Hypothalamus (HT) is a brain structure which serves as a coordination center for several vital body functions. Craniopharyngioma (CP) is a pituitary tumor with high morbidity, primarily due to HT lesion. READ MORE

  5. 5. Magnetic resonance imaging in dementia : A study of brain white matter changes

    Author : Lena Bronge; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Non-specific white matter changes (WMC) in the brain are common findings in the elderly population. Although they are frequently seen in non-demented persons, WMC seem to be more common in demented patients.The significance of these changes, as well as their pathophysiological background is incompletely understood.
