1. The influence of social relationships and leisure activity on adult cognitive functioning and risk of dementia : Longitudinal population-based studies
Sammanfattning : Today, as we live longer, dementia diseases are becoming more prevalent around the world. Thus, further knowledge of how to maintain levels of cognitive functioning in old age and how to identify factors that postpone the onset of dementia are of acute interest. Lifestyle patterns and social life are important aspects to consider in this regard. LÄS MER
2. Longitudinal cognitive changes in medically and surgically treated patients with drug resistant partial epilepsy
Sammanfattning : When this study was initiated, there were few published longitudinal studies on cognition in medically treated patients with refractory epilepsy, and none included reassessment data from healthy controls. At the time there were no long-term reports on surgically treated epilepsy patients. LÄS MER
3. On electroconvulsive therapy in depression : Clinical, cognitive and neurobiological aspects
Sammanfattning : Electroconvulsive therapy (ECT) is used worldwide to treat severe mental disorders. The most common mental disorder, and the third leading cause of disease burden in the world is depression. The clinical efficacy of ECT for severe depression is well-established. LÄS MER
4. The aging brain and changes in cognitive performance : Findings from morphometry and quantitative susceptibility mapping of iron
Sammanfattning : Brain aging is a heterogeneous phenomenon, and this thesis illustrates how the course of aging can vary within individuals over time and between individuals as a function of age, sex, and genetic variability. We used two contrasts from magnetic resonance imaging (MRI), namely spin-lattice T1-weighted imaging, and quantitative susceptibility mapping (QSM) from gradient-echo images, to picture the aging brain, by means of morphometric measures and brain-iron concentrations.

5. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations
Sammanfattning : Aging is typically associated with declining mental abilities, most prominent for some forms of memory. There are, however, large inter-individual differences within the older population. Some people experience rapid decline whereas others seem almost spared from any adverse effects of aging. LÄS MER
