Cognitive decline represents a severe non‐motor symptom of Parkinson's disease (PD) that can significantly reduce the benefits of subthalamic deep brain stimulation (STN DBS). Here, we aimed to describe post‐surgery cognitive decline and identify pre‐surgery cognitive profile associated with faster decline in STN DBS‐treated PD patients. A retrospective observational study of 126 PD patients treated by STN DBS combined with oral dopaminergic therapy followed for 3.54 years on average (SD = 2.32) with repeated assessments of cognition was conducted. Pre‐surgery cognitive profile was obtained via a comprehensive neuropsychological examination and data analysed using exploratory factor analysis and Bayesian generalized linear mixed models. On the whole, we observed a mild annual cognitive decline of 0.90 points from a total of 144 points in the Mattis Dementia Rating Scale (95% posterior probability interval [−1.19, −0.62]) with high inter‐individual variability. However, true score changes did not reach previously reported reliable change cut‐offs. Executive deficit was the only pre‐surgery cognitive variable to reliably predict the rate of post‐surgery cognitive decline. On the other hand, exploratory analysis of electrode localization did not yield any statistically clear results. Overall, our data and models imply mild gradual average annual post‐surgery cognitive decline with high inter‐individual variability in STN DBS‐treated PD patients. Nonetheless, patients with worse long‐term cognitive prognosis can be reliably identified via pre‐surgery examination of executive functions. To further increase the utility of our results, we demonstrate how our models can help with disentangling true score changes from measurement error in future studies of post‐surgery cognitive changes.

Emotional creativity (EC) is a pattern of cognitive abilities and personality traits related to originality and appropriateness in emotional experience. EC has been found to be related to various constructs across different fields of psychology during the past 30 years, but a comprehensive examination of previous research is still lacking. The goal of this review is to explore the reliability of use of the Emotional Creativity Inventory (ECI) across studies, to test gender differences and to compare levels of EC in different countries. Thirty-five empirical studies focused on EC were retrieved and the coefficients required for the meta-analysis extracted. The meta-analysis revealed that women showed significantly higher EC than men (total N = 3,555). The same gender differences were also found when testing scores from three ECI subscales, i.e. emotional novelty, emotional preparedness and emotional effectiveness/authenticity. When comparing EC in 10 different countries (total N = 4,375), several cross-cultural differences were revealed. The Chinese sample showed a significantly lower average ECI total score than all the other countries. Based on the integration of results, the avenues for future research on EC and the breadth of influence of the concept of EC across different fields of psychology are discussed.

AbstractThe present study aimed to test the hypothesis that the total word length on the Memory subtest of the Czech version of the MoCA, which is 12 syllables compared to the English version of 7 syllables, would have a significant effect on Delayed Recall scores compared to the newly created well-balanced version of the test (further MoCA-WLE). In the original Czech version of MoCA, we replaced the 12-syllable word list in the Memory subtest with a 7-syllable list (MoCA-WLE) to make it equivalent to the standard English version in this respect. We analyzed data from 83 participants in the original MoCA group (70.63 ± 7.01 years old, 14.61 ± 3.17 years of education, 30.12% males) and 83 participants in the MoCA-WLE group (70.72 ± 6.95 years old, 14.93 ± 3.48 years of education, 30.12% males). We did not find evidence for a significant word-length effect in the original MoCA versus MoCA-WLE Delayed Recall in either the Mann–Whitney U test (W = 3418.0, p = .932) or multilevel binomial regression (b = 0.10, 95% posterior probability interval [−0.46, 0.68]). The present study shows cross-cultural limits in the adaptation of the test material. The results underline the caveats of such an approach to test adaptation. Fortunately, 12-syllables in the MoCA Memory Czech version versus the original 7-syllable list did not show a detectable word-length effect. We did not find evidence for differential item functioning or cultural item bias. The original MoCA Czech version is psychometrically comparable to the original English version.

AbstractIn this study, we explored the effect of non-computerized cognitive rehabilitation in patients with Parkinson’s disease in comparison with an intervention with elements of music therapy after the completion of a three-month program and one year after the end of the intervention. After the initial neuropsychological examination, the respondents were divided into two intervention groups. The experimental group (n = 26) underwent a twelve-week program of cognitive rehabilitation at a frequency of 60 minutes once a week. The control group (n = 27) underwent an intervention program with elements of music therapy at the same frequency. Respondents who underwent the cognitive rehabilitation program improved in the delayed recall from visual memory in the follow-up examination after the end of the cognitive intervention. One year after the end, the effect of cognitive rehabilitation persisted in delayed recall from visual memory and in executive mental flexibility. Cognitive rehabilitation is an effective approach to compensate for cognitive deficits in P D, but other approaches to cognitive stimulation may be equally effective. [ABSTRACT FROM AUTHOR]

Emotion concepts are representations that enable people to make sense of their own and others' emotions. The present study, theoretically driven by the conceptual act theory, explores the overall spectrum of emotion concepts in older adults and compares them with the emotion concepts of younger adults. Data from 178 older adults (⩾55 years) and 176 younger adults (20–30 years) were collected using the Semantic Emotion Space Assessment task. The arousal and valence of 16 discrete emotions – anger, fear, sadness, happiness, disgust, hope, love, hate, contempt, guilt, compassion, shame, gratefulness, envy, disappointment, and jealousy – were rated by the participants on a graphic scale bar. The results show that (a) older and younger adults did not differ in the mean valence ratings of emotion concepts, which indicates that older adults do not differ from younger adults in the way they conceptualise how pleasant or unpleasant emotions are. Furthermore, (b) older men rated emotion concepts as more arousing than younger men, (c) older adults rated sadness, disgust, contempt, guilt, and compassion as more arousing and (d) jealousy as less arousing than younger adults. The results of the present study indicate that age-related differentiation of conceptual knowledge seems to proceed more in the way that individuals understand how arousing their subjective representations of emotions are rather than how pleasant they are.

Objectives: To characterize the inclusion of cognition in definitions of successful aging (SA) according to empirical studies published in peer-reviewed journals. Methods: A systematic review across ISI Web of Knowledge. Results: Of the 74 included studies, there were 65 studies (87.8%) analyzing cognition as one component of multicomponent SA model (cognitive component studies), and 9 studies (12.2%) focusing solely on successful cognitive aging (SCA studies). Most of the studies operationalized cognition in SA by defining SA group and analyzing single SA indicators. A minority of the studies calculated the SA index. Finally, emergent techniques to operationalize SA as a latent variable and emergent field of cognition in SA in pathology were identified. Conclusions: The results highlight that cognition is being included in SA using different levels of complexity. Even though research investigating SA in pathology is emerging, there is currently a lack of utilization of the concept in pathological and at-risk populations. Clinical implications: The current research of cognition in SA provides several valid options to evaluate if a person is aging successfully. The emerging research indicates that people from at-risk and pathological populations can age successfully. [ABSTRACT FROM AUTHOR]

Exceptional cognitive aging, or superaging is a recent area of research. SuperAgers are defined as persons aged at least 80 years who have youthful episodic memory. Studies are scarce and very little is known about their lifestyle and leisure activities including their engagement in physical activity, which is otherwise known to be associated with better health. The project aims to identify associations between a lifelong physically active lifestyle, objective fitness and cognitive superaging in old-old women. COSACTIW is a cross-sectional ex-post-facto study. Herewith, we present its protocol. There were 225 women aged 80-96 years tested who reported that their engagement in physical activity between the ages of 30 to 60 years was at least on the level recommended for adults by the World Health Organization, i.e. at least 150 minutes of moderate-intensity aerobic physical activity per week. Episodic memory was tested with Rey Auditory Verbal Learning Test, non-memory tests were Trail Making Test, Verbal fluency – animals, and Boston Naming Test – 30 item version. Several questionnaires were used to map previous and current leisure activities. Objective data were obtained with the Senior Fitness Test. We also present benchmark data from a previous Czech study of cognitively normal older persons, NANOK, to whom we will compare our sample. Specifically, we are going to use a subsample of 70 women, aged 80-94 years, who were selected from the NANOK sample using the same inclusion criteria as in COSACTIW. There were 23 (32.9%) SuperAgers among them. Our findings may offer insights into preventive strategies for successful aging and cognitive resilience. [ABSTRACT FROM AUTHOR]
