2. 1. The influence of social relationships and leisure activity on adult cognitive functioning and risk of dementia : Longitudinal population-based studies

   Author : Daniel Eriksson Sörman; Michael Rönnlund; Anna Sundström; Lars-Göran Nilsson; Martin Lövdén; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognitive functioning; cognition; memory; dementia; Alzheimer’s disease; cognitive reserve; reverse causality; old age; middle age; leisure activity; social relationships; social network; longitudinal; Psychology; psykologi;

   Abstract : 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. READ MORE

4. 2. Longitudinal cognitive changes in medically and surgically treated patients with drug resistant partial epilepsy

   Author : Lena Andersson-Roswall; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; drug resistant partial epilepsy; epilepsy surgery; longitudinal cognitive changes;

   Abstract : 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. READ MORE

6. 4. The aging brain and changes in cognitive performance : Findings from morphometry and quantitative susceptibility mapping of iron

   Author : Ninni Persson; Håkan Fischser; Kristine B. Walhovd; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; brain aging; volumes; ndividual differences; QSM; cognitive aging; iron; episodic memory; fluid-; crystalized abilities; sex differences; gender differences; Psychology; psykologi;

   Abstract : 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.

7. 5. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

   Author : Sara Pudas; Jonas Persson; Lars Nyberg; Emrah Düzel; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aging; episodic memory; individual differences; longitudinal assessment; magnetic resonance imaging; hippocampus; frontal cortex; Psychology; psykologi;

   Abstract : 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. READ MORE
