  1. 36. Neuroimaging biomarkers in Alzheimer’s disease

    Författare :Farshad Falahati Asrami; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer’s disease (AD) is characterized by an accumulation of abnormal plaques and tangles in the brain, a process that is estimated to begin years before the appearance of clinical symptoms. Individuals with subjective memory decline (SMD) or mild cognitive impairment (MCI) run a higher risk of developing AD than cognitively normal (CN) people. LÄS MER

  3. 37. Magnetic resonance studies in Alzheimer's disease

    Författare :Eric Westman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) is one of the most common forms of neurodegenerative disorders connected with gradual loss of cognitive functions such as episodic memory. The disease is related to pathological amyloid depositions and hyper phosphorilation of structural proteins in the brain which lead to progressive loss of function, metabolic alterations and structural changes in the brain.

  4. 38. Neural correlates of hand function in typically developing individuals and children with unilateral cerebral palsy

    Författare :Linda Holmström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The ability to use our hands is crucial in order to achieve the goals of almost all activities in everyday life. Most of us learn how to handle objects and adjust our hand and finger movements to perform increasingly difficult tasks during childhood and adolescence. LÄS MER

  5. 39. Diffusion magnetic resonance imaging for investigating alterations in brain organization after injury during early development : with specific reference to the motor and visual system

    Författare :Finn Lennartsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Disturbances or injuries to the brain during early development cause different types of structural abnormalities, depending mainly on the stage of maturation of the brain at the time of the insult. These are, herein, collectively referred to as early brain lesions. LÄS MER

    Sammanfattning : 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. LÄS MER
