Motivationale Reservekapazität: Leichte kognitive Beeinträchtigung und Alzheimerdemenz

Motivationale Fähigkeiten im mittleren Lebensalter sind mit psychischer und körperlicher Gesundheit assoziiert. In einer Querschnitts- und einer Längsschnittstudie wurde der Zusammenhang motivationaler Fähigkeiten mit dem Risiko einer leichten kognitiven Beeinträchtigung (MCI) und Alzheimer-Demenz (AD) untersucht. Die Ergebnisse geben Hinweise darauf, dass motivationale Reservekapazität möglicherweise als protektiver Faktor gegen die Manifestation kognitiver Beeinträchtigung im höheren Lebensalter wirkt

Therapie bei älteren Menschen

Störungsmodelle in der Alterspsychotherapie beziehen neben schulenspezifischen Störungs- und Behandlungsmodellen auch gerontologische Konzepte mit ein. Daher werden zunächst das Alters- und störungsspezifische Rahmenmodell sowie das Modell der selektiven Optimierung mit Kompensation dargestellt. Sie zeigen, dass nicht nur erschwerende Faktoren (wie Multimorbidität, Verluste, Fähigkeitseinschränkungen) sondern auch erleichternden Faktoren (wie Bewältigungs- und Lebenserfahrung, angepasste Wohlbefindensregulation) relevant sind. Allgemeine altersbezogene Modifizierungen psychotherapeutischer Techniken werden beschrieben. Interventionen in der Alterspsychotherapie sind zum einen Modifikationen bestehender Verfahren, die in diesem Kapitel für die Behandlung von Demenz, Depression, Angst und Traumafolgen dargestellt werden. Zum anderen gibt es speziell für diese Altersgruppe neu entwickelte Verfahren. Hier wird die Lebensrückblicksintervention beschrieben, die gut in einen psychotherapeutischen Gesamtbehandlungsplan eingebettet werden kann. Ein Fallbeispiel illustriert das Vorgehen dieser Intervention. Schließlich gibt es einige Störungen und Probleme, die in jüngeren Altersgruppen nicht vorhanden sind, von denen hier die Demenz sowie Fallangst und ihre Behandlung dargestellt werden

No Band Color Effects on Male Courtship Rate or Body Mass in the Zebra Finch: Four Experiments and a Meta-Analysis

Replication of experiments is essential for distinguishing real effects from type 1 errors and idiosyncrasies. One of the most replicated experiments in behavioral ecology is the presumed manipulation of male attractiveness in zebra finches by adding red or green color bands. Red-banded males were found to have higher fitness than green-banded males, and most empirical evidence suggests that this effect is mediated by female mating preferences rather than by male-male competition. A recent study, however, reported that color bands affected male courtship rate and body mass independently of female behavior. If this effect was real, some earlier findings of female preferences and maternal effects on offspring traits could potentially be reinterpreted as being mediated indirectly via effects on male behavior. This new perspective seems appealing also in light of a growing interest in bi-directional feedback mechanisms between endocrinology and ornamentation. However, here we report four independent failures to replicate this effect of color bands on courtship rate and body mass. Combining this new experimental data with all the published evidence in a meta-analysis shows that color bands seem to affect neither male courtship rate (average effect size d = 0.02) nor male body mass (d = −0.07). The present case is a reminder that replication of experiments lies at the heart of distinguishing between real effects and false positive findings

Motivational reserve: lifetime motivational abilities contribute to cognitive and emotional health in old age

The authors recently developed the concept of motivational reserve, which implies a set of motivational abilities that provide individuals with resilience to neuropathological damage. This study investigated how lifetime motivational abilities are associated with current cognitive status, mild cognitive impairment, and psychological well-being in old age. A community sample of 147 participants without dementia between 60 and 94 years of age, stratified for age group, sex, and education, completed motivation and well-being questionnaires and cognitive tests. A new procedure was used to estimate their midlife motivational and cognitive abilities on the basis of their main occupation using the Occupational Information Network (O*NET) system. O*NET-estimated motivational abilities predicted cognitive status, psychological well-being, and odds of mild cognitive impairment, even when age, sex, education, and cognitive ability were controlled. Although O*NET-estimated cognitive abilities were not significant predictors, scores on a measure of crystallized intelligence were associated with current cognitive status and odds of mild cognitive impairment. Findings suggest that motivational reserve acts as a protective factor against the manifestation of cognitive impairment and emotional problems in later life

Apathy: a separate syndrome from depression in dementia? A critical review

Apathy and depression are the most prevalent neuropsychiatric symptoms in Alzheimer's disease and mild cognitive impairment. Despite much research on apathy and depression in dementia, the nosological position of apathy as a separate syndrome from depression remains debated. This literature review provides a critical analysis of the areas of clinical manifestation, symptomatology, assessment, prevalence and neuropathology. Evidence does not provide a clear view of the nosological position of apathy in dementia for symptoms and neuropathology. However, the ambiguity of the evidence may be attributed in large part to a lack of clarity in definition and etiology, clinical criteria and assessment overlap. Given the evidence, it is concluded that the argument in favor of apathy as a separate syndrome from depression in dementia is persuasive. Reaching a consensus on the definition and nosological position of apathy within dementia is vital to provide patients and caregivers with the support they require, increase understanding of risk factors, and enable comparisons across research and practic

Delay of gratification in old age: assessment, age-related effects, and clinical implications

Delay of gratification (DoG), the ability to reject immediately available smaller rewards in favor of later larger rewards, has been a topic of continuous research interest for almost 60 years. Although numerous studies have explored this construct and its effects on wellbeing, social behavior, cognitive abilities, and academic success in children, DoG studies in adulthood and old age are scarce. Instead, delay discounting (DD), that is, the degree to which individuals devalue delayed rewards, has been used in samples of adults and older individuals, and is of particular interest in clinical studies. Findings from DD research suggest that the preference for delayed rewards increases from childhood to early adulthood, and then decreases from middle age to old age. The main aim of this review is to elucidate the importance of DoG in adulthood and old age. First, the review explores the theoretical status of DoG by specifying the relationships and distinctions between DoG and related constructs. Second, it provides an overview of DoG measurements, from traditional to novel. Third, the effects of DoG on development and wellbeing are explored. Fourth, age-related differences in DoG are summarized. Lastly, the review closes with conclusions, clinical implications, and the outlook for possible further research direction

The delay of gratification test for adults: Validating a behavioral measure of self-motivation in a sample of older people

Most previous delay of gratification tests were developed for children and are inappropriate for application in adults. The authors therefore developed the Delay of Gratification Test for Adults (DoG-A), which includes four types of reward that are meaningful to adults, namely snacks, real money, hypothetical money, and magazines. Four subscores and two composite scores can be calculated. This study is the first to evaluate the DoG-A and to investigate its association with external variables. A community sample of 147 cognitively healthy participants aged between 60 and 94years completed a questionnaire and cognitive tests measuring delay discounting, self-regulation, motivational self-concept, personality, wellbeing, and cognitive function. The intercorrelations of the subscales were low to medium and the internal consistency of the composite scores was moderate (α=.4), indicating relative domain independence of the four reward types. The nomological net established by investigating the relations of the DoG-A with other constructs proved to be fairly meaningful. The correlations of all subscales with the delay discounting rate were significant and moderate. The Snacks subscale showed the most consistent pattern of results in terms of moderate positive correlations with self-reported motivation regulation, optimism, dutifulness, and deliberation. The Snacks subscale also correlated with various measures of wellbeing. A regression analysis showed that DoG Snacks remained a significant predictor of wellbeing when self-reported self-regulation and other variables were controlled. These findings indicate that the DoG-A yields an interpretable behavioral measure of self-motivation and offers a developmentally adequate extension of the delay of gratification paradigm for use with adult
