1. 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.

Sammanfattning : Aging, also in the absence of pathological conditions, is associated with cognitivedecline, especially in so called fluid abilities, such as episodic memory andexecutive functions. Due to an ongoing demographic shift, a larger part of thepopulation will reach higher ages, and more people will be affected by age-relatedcognitive decline. LÄS MER

4. Birth cohort differences in cognitive aging: Secular trends in cognitive functioning and decline over 30 years in three population-based Swedish samples
Sammanfattning : 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. LÄS MER
5. Using Mobile Health Technology to Support Health-related Quality of Life : From the Perspective of Older Adults with Cognitive Impairment
Sammanfattning : The prevalence of cognitive impairment and illness increases with age. For older adults, maintaining or improving health-related quality of life (HRQoL) in the early stages of cognitive impairment is important to prevent consequences related to the progression of the condition.
