    Sammanfattning : The general aim of this thesis was to study asymmetric activation of the neocortex in normal subjects, using the rCBF technique and different cognitive tasks. The aim was also to study individual and group variations of asymmetric activation, as well as factors pertaining to these variations. The thesis is based on four investigations. LÄS MER

  3. 2. Depression and cognition in the elderly : neuroimaging perspective

    Författare :Aleksandra Lebedeva; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis examines the relationship between depression and brain structure in the elderly with (Study I, III) and without (Study II, IV) cognitive impairment (Alzheimer’s disease and mild cognitive impairment). Individuals from four independent cohorts were included. LÄS MER

  4. 3. Mild cognitive impairment neuroimaging markers for early diagnosis of dementia

    Författare :Chaorui Huang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : This thesis concerns the investigation of mild cognitive impairment (MCI) and Alzheimer's disease (AD) using single photon emission computed tomography (SPECT) and quantitative electroencepholography (qEEG). In study I, The qEEG values were cross-sectionally compared between AD, MCI and controls. LÄS MER

  5. 4. White matter connections : developmental neuroimaging studies of the associations between genes, brain and behavior

    Författare :Fahimeh Darki; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Development of cognitive abilities across childhood and adulthood parallels brain maturation in typically developing samples. Cognitive abilities such as reading and working memory have been linked to neuroimaging measures in relevant brain regions. LÄS MER

  7. 5. Autism spectrum disorder in adults : biological dimensions

    Författare :Irina Manouilenko; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Autism Spectrum Disorder (ASD) is a group of neurodevelopmental conditions characterized by difficulties in social interaction, communication and the presence of repetitive or stereotyped behaviors. Previous studies have demonstrated structural and functional abnormalities in different brain regions in ASD. LÄS MER
