Full textAfter an extensive review of what is known about the genetics and neuroscience of general intelligence and a methodological note emphasising the necessity to consider latent variables in cognitive neuroscience studies, exemplified by a re-analysis of published results, the most well-established brain correlate of intelligence, brain size, is revisited from an evolutionary genetic perspective. Estimates of the coefficient of additive genetic variation in brain size suggest that there was no recent directional selection on brain size, questioning its validity as a proxy for intelligence in evolutionary analyses. Instead, correlations of facial fluctuating asymmetry with intelligence and information processing speed in old men suggest that organism-wide developmental stability might be an important cause of individual differences in cognitive ability. The second half of the thesis focuses on cognitive ageing, beginning with a general review. In a sample of over 130 subjects it has then been found that the integrity of different white matter tracts in the brain is highly correlated, allowing for the extraction of a general factor of white matter tract integrity, which is correlated with information processing speed. The only tract not loading highly on this general factor is the splenium of the corpus callosum, which is correlated with changes in intelligence over 6 decades and mediates the effect of the beta2 adrenergic receptor gene (ADRB2) on cognitive ageing, possibly due to its involvement in neuronal compensation processes. Finally, using a novel analytic method for magnetic resonance data, it is shown that more iron depositions in the brain, presumably markers of a history of cerebral microbleeds, are associated with both lifelong-stable intelligence differences and age-related decline in cognitive functioning.

Full textLa población mundial está envejeciendo rápidamente y hay un incremento de la población en áreas urbanas. Por este motivo, existe una necesidad emergente de entornos que beneficien un envejecimiento saludable. La exposición a espacios verdes puede fomentar un envejecimiento saludable, promoviendo la actividad física, la salud mental y el apoyo social y reduciendo la exposición a la contaminación del aire, el calor y el ruido. Por lo tanto, el objetivo de esta tesis fue investigar la asociación entre la exposición a espacios verdes a largo plazo y el envejecimiento saludable, considerando la función cognitiva, física, cardiovascular y metabólica. Esta tesis incluye dos revisiones sistemáticas y cuatro estudios longitudinales de cohorte. Los estudios longitudinales se basaron en seguimientos repetidos de la cohorte de Whitehall II de adultos de mediana edad y adultos mayores del Reino Unido. Nuestros resultados sugirieron que los participantes que vivían en áreas con más espacios verdes tenían un deterioro cognitivo más lento, una menor pérdida de la capacidad física, una progresión reducida de la rigidez arterial y un menor riesgo de síndrome metabólico durante el período de estudio. En conclusión, los resultados de esta tesis sugirieron que la exposición a espacios verdes a largo plazo podría contribuir a la promoción de un envejecimiento saludable.

Full textThe older population is increasing, as is life expectancy. Technical devices are becoming more widespread and used for many everyday tasks. Knowledge about new technology is important to remain as an active and independent part of the society. However, if an old user group should have equal access to this technology, new demands will be placed on the design of interfaces and devices. With respect to old users it is and will be important to develop technical devices and interfaces that take the age-related decline in physical and cognitive abilities into account. The aim of this work was to investigate to what extent the age-related cognitive decline affects performance on different computer-related tasks and the use of different interfaces. With respect to the use of computer interfaces, two studies were conducted. In the first study, the information was presented with a hierarchical structure. In the second study the information was presented as a 3D-environment, and it was also investigated how an overview map could support navigation. The third study examined the age-related cognitive decline in the use of a small mobile phone display with a hierarchical information structure. The results from the studies showed that the most pronounced age-related difference was found in the use of the 3D-environment. Within this environment, prior experience was found to have the largest impact on performance. Regarding the hierarchical information structures, prior experience seemed to have a larger impact on performance of easy tasks, while age and cognitive abilities had a larger impact on performance of more complex tasks. With respect to navigation aids, the overview map in the 3D-environment did not reduce the age-differences; however, it contributed to a better perceived orientation and reduced the feeling of being lost.

Full textIntroduction: Population ageing has been accompanied by a worldwide increase in the pervasiveness of dementia. However, a systematic review of the literature shows that little is known about the prevalence of dementia and cognitive impairment among ethnically different, such as indigenous, populations. This is particularly relevant given the increase in life expectancy of this population and, consequently the number of elderly individuals, as well as the modification in their morbimortality profile. Objective: To identify the prevalence of cognitive impairment in the indigenous Brazilian population through an assessment of its cognitive performance profile, subjective cognitive decline and mood and associating it with sociodemographic factors, habits, health history and mood. Method: 217 individuals were included of equal to or greater than 50 years of age, of both sexes, of the Mura ethnic group, and residents of the Pantaleão village, in the municipality of Autazes, Amazonas. The participants were submitted to evaluation testing of attentiveness, operating memory, short-term and long-term declarative memory, verbal fluency, visual-constructional ability, as well as evaluation of mood, symptoms of depression, subjective cognitive decline and functional performance. Results: The prevalence of cognitive impairment varied according to age group. While in the total population sample, which included individuals 50 years of age and older, the prevalence of cognitive impairment was 43.3%, among participants 60 years or older, this prevalence increased to 43.7% and to 51.1% for those 65 years or older. In relationship to associated factors, age and schooling influenced the chances of cognitive impairment among all of the age groups. In participants of 50 years or older, for each year of age, there is a 3% increase in the chance of cognitive impairment (OR = 1,03) and for each year of schooling this chance diminishes by 26% (OR = 0,74). On the other hand, in participants of 60 years of age or more, for each year of age, there is a 9% increase in the chance of cognitive impairment (OR = 1,09) and for each year of schooling, this chance diminishes by 29% (OR = 0,71). Beyond age and schooling, the body mass index negatively influenced the chance of cognitive impairment in participants aged 50 years and 60 years. Beyond this, for each household income unit, there is a 48% decrease in the chance of cognitive impairment in the elderly participants aged 60 years. Compared with indigenous individuals without cognitive impairment, those with cognitive impairment performed worse on all cognitive tests, except those of verbal fluency and visual-constructional ability, besides a greater intensity of subjective cognitive decline and symptoms of depression (p 0.05). Conclusion: The prevalence of cognitive impairment in adults and indigenous individuals increases among older age groups and the chance of acquiring some kind of impairment increases among older participants with less schooling and lower household incomes. These findings can contribute to the implementation of public policies related to indigenous health care and the training of health professionals, including nursing teams, for the early identification of individuals vulnerable to the development of cognitive impairment.

Full textThis dissertation is formed by two works that aim to investigate executive dysfunction on ageing. Recent studies suggest the existence of executive dysfunctions in Mild Cognitive Impairment (MCI). The aim of the first study was to verify the presence of executive dysfunctions in patients with MCI. The instruments used were the Wisconsin Card Sorting Test (WCST) and the Iowa Gambling Test (IGT). Ten patients with and 27 without MCI were assessed. The data were analyzed through Student t test for independent samples and analysis of variance (ANOVA) for repeated measures. The results did not show significant difference between groups in the answer rates of WCST and in the number of cards withdrawn from each pack of cards in the IGT. The study of the performance evolution in the IGT revealed a qualitative difference between the groups. Elderly without MCI learn along the task, while elderly with MCI did not, suggesting an interference of memory systems in decision making. The Iowa Gambling Test has been an instrument used in the assessment of decision making. The aim of the second study was to investigate if changes in the application procedures of the instrument interfere in the performance through the test execution. A cross sectional study was carried out comparing two groups of healthy elderly in two variations of the instrument. The group I included 27 participants, which executed the task without clue of visual reinforcement. The group II was composed by 17 participants, submitted to the task with clue. The data were analyzed through the Student t test for independent samples and ANOVA for repeated measures. It was found statistically significant difference between the two groups in the execution of the test in relation to risk aversion (F=2,466; p=0,05; df=2). The results indicate that a clue of visual reinforcement permits greater allocation of attention resources and of working memory, allowing elderly to make least risky decisions.
