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

   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. 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.

5. 3. Birth cohort differences in cognitive aging: Secular trends in cognitive functioning and decline over 30 years in three population-based Swedish samples

   Author : Peter Karlsson; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Aging; cardiovascular risk factors; cognitive decline; cohort differences; fluid and crystallized abilities; Flynn effect; longitudinal;

   Abstract : The overarching aim of this thesis was to investigate birth cohort differences in level of cognitive functioning and change in later life in three population-based representative samples drawn from the Gerontological and Geriatric Population Studies in Gothenburg (H70), Sweden. We used data from cohorts, born in 1901-02, 1906-07, and 1930, measured at ages 70, 75, and 79 on the same cognitive measures. READ MORE

6. 4. The reserve concept in patients with Mild Cognitive Impairment – new approaches

   Author : Sindre Rolstad; Göteborgs universitet; []
   Keywords : neuroscience; cognition; neuropsychology;

   Abstract : The concept of reserve stems from the observation that premorbid factors, e.g. education, result in variation in the response to any kind of brain pathology. As subjects with higher reserve tolerate more neuropathology, symptomatic expression of pathology is delayed. READ MORE

7. 5. Pathophysiological Mechanisms and Diagnostic Markers in Alzheimer’s Disease

   Author : Joakim Hertze; Klinisk minnesforskning; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; mild cognitive impairment; white matter lesions; brain reserve; blood-brain barrier; angiogenesis; neuroinflammation; neurogranin; YKL-40; VEGF; IGF; ICAM-1; VCAM-1;

   Abstract : Alzheimer’s disease (AD), the most common cause of dementia, is a growing concern. As the life expectancy increases across the globe, the number of affected people is estimated to reach 100 million by 2050. READ MORE
