  1. 1. Frontotemporal dementia in late life: Prevalence, risk factors and mortality

    Författare :Thorsteinn Gislason; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Frontotemporal dementia; Older adullts; Prevalence; Risk factors; Mortality;

    Sammanfattning : Aims: The overall aim of this thesis was to increase knowledge about late-life behavior variant frontotemporal dementia (bvFTD). One aim was to estimate the prevalence of bvFTD among older adults and to determine the agreement between different bvFTD criteria. LÄS MER

  3. 2. Neurodegenerative Biomarkers in Healthy Elderly - with special reference to the preclinical pattern of biological and cognitive markers for Alzheimer’s disease

    Författare :Erik Stomrud; Klinisk minnesforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral blood flow; EEG; phosphorylated tau protein; amyloid beta protein; tau protein; cerebrospinal fluid; biomarkers; preclinical Alzheimer s disease; Alzheimer s disease; MCI; dementia; SPECT; memory; cognition; early diagnosis; control groups;

    Sammanfattning : Background: Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by tau and amyloid brain pathology. With the gradual degeneration of neurons, cognitive symptoms will arise and the affected individual will eventually develop AD dementia. LÄS MER

  4. 3. The aging frontal lobe in health and disease : a structural magnetic resonance imaging study

    Författare :Olof Lindberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cortical and subcortical regions of the brain decrease in volume in normal as well as pathological aging. Previous studies indicate that certain parts of the brain, like the prefrontal cortex, may be particularly vulnerable to age-related processes which are manifested by significant volume loss in this region.

  5. 4. Cognitive functioning in the preclinical stages of Alzheimer's disease and vascular dementia

    Författare :Sari Jones; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cognition; preclinical; Alzheimer s disease; vascular dementia; neuropsychology;

    Sammanfattning : This doctoral thesis concerns cognitive functioning in the preclinical stages of Alzheimer's disease (AD) and vascular dementia (VaD). It is based on five empirical studies using data from the Kungsholmen Project, a longitudinal population-based study of aging and dementia targeting persons 75 years and older, living in the Kungsholmen District in Stockholm, Sweden.

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

    Författare :Lena Bronge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : 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.
