Gero 599: Cognitive Neuroscience of Aging Course Location: Gero 224 Gero 599: Cognitive Neuroscience of Aging Course location: Gero 224 Meeting time: Thursdays 2-4:50 PM Instructor: Mara Mather, Ph.D. Office hours: Mondays 2:30-3:30 PM and by appointment (Gero 216b) Overview: How does the brain change as we age and what are the implications for cognition? This course covers new developments in research in cognitive neuroscience and aging, with a focus on the consequences for memory and emotion. Course Requirements A. Come up with discussion questions about the articles before the seminar and participate fully in the seminar discussion. As part of this requirement, you will need to email me at least one question about each of the readings by 3 PM the day before each class. In addition, you should bring a printout of these questions and try to raise at least one of them during the class discussion. Grading criteria: 1) How clear/comprehensible are the questions? 2) Are the questions thought provoking? 3) Do the questions have “right” answers that only an expert would know? (Avoid these—they rarely are good discussion questions.) 4) Do the questions highlight something interesting in the readings that might not have been noticed by others? B. Four course presentations (you will be assigned dates spread throughout the semester). Each presentation will be strictly limited to 10 minutes (shorter presentations that leave more time for discussion are fine) except for #4, which will be limited to 15 minutes. 1. New experiment design: Design a study investigating some aspect of the cognitive neuroscience of aging and present the research proposal to the group. Grading criteria: 1) How effectively does the presentation convince the audience that the question is interesting and important? 2) Does the study have a testable hypothesis? 3) Are there clear predictions for the study? 4) Does the plan effectively test the research hypotheses? 4) How easily can the audience understand the design of the study? 2. Address the session topic with some additional research findings: Present a summary of one or more studies (not already assigned in our reading list) that you believe help address the question posed for that day’s discussion session. Grading criteria: 1) How clearly does the presentation describe the related findings in the literature? 2) How effectively does the presentation help answer the session topic question? 3. Convey some other related findings: Tell the group about some interesting research findings related to the cognitive neuroscience of aging that are not covered in this seminar. Along with this, you should turn in a citation for an article (not already on the syllabus) that you would like the group to discuss on the last day of the course. You should include a short explanation of why you would like to include this article. This citation can be any article related to the course material. We will vote on which articles to read. If your suggestion is chosen, you are responsible for lending the group a master copy. Grading criteria: 1) How interesting is the presentation? 2) How effectively did we learn about the topic? 4. Get your classmates involved: Take over the seminar for 15 minutes once during the quarter and engage your classmates in an interactive activity related to the week’s readings, whether it is a debate, quiz about the readings, small group discussions or some other activity. Also, turn in a one-page summary of the activity by 3 PM Tuesday two days before the session meets. Grading criteria: 1) How interesting was the activity? 2) Did the activity help seminar members learn something new about the topic, solidify knowledge of something in the readings, or clarify something confusing? 3) Was the activity plan clear and comprehensible? 4) Was the activity plan turned in on time? 5) Extra credit – was the activity fun? Tips for your presentations: 1. Speak through it out loud beforehand to make sure the timing is right. 2. Make it interesting! Tell us why you think the topic is exciting, new or different. C. Questions for classmates’ presentations: At the end of each class, turn in at least one written question for each of the presentations made that day (questions are not required for the group activity presentation type). Grading criteria: 1) How clear/comprehensible are the questions? 2) Are the questions thought provoking? 3) How important is the question for the topic being presented? This seminar will not have a final exam or paper. Final grade composition: Grades on the questions emailed before the discussion, the four presentations and the questions turned after class will each contribute 1/6th of the final grade. Your lowest grade on one set of emailed questions and one set of in-class questions will be dropped. Thus, if you miss one seminar meeting, there will be no penalty. If you miss more than one seminar meeting, you may write a short response (1-3 paragraphs) to each of the readings for the missed meetings to make up for the missed in- class questions. This should not be a summary of the readings, but instead a response to them. This could be either 1) an evaluation of the methods, results or interpretation; 2) a discussion of how something brought up in the article relates to other findings; or 3) how it has further implications not discussed in the article.

Abstract: Hypertension is one of the most common chronic diseases and a major risk factor for stroke, myocardial infarction and cardiovascular death. Cognitive frailty is an important predic- tor of all-cause mortality and dementia in aging individuals. Hypertension is closely related to cognitive frailty and these two conditions often coexist in aging individuals. Few studies have explored the relationship between hypertension and cognitive frailty in the Chinese population. This study investigates the epidemiological characteristics of and factors related to cognitive frailty in aging Chinese patients with hypertension. In total, cognitive function, weakness, social support, depression and sociodemographic were assessed in 305 participants aged 60 and over. Univariate and multivariate logistic regression models were constructed. The prevalence of cognitive frailty in aging Chinese hypertensive patients was 9.8% (95% CI = 6.4–13.2%). After adjusting for confound- ing variables, logistic regression showed that the course of hypertension (6–10 years, OR = 8.588, Citation: Wang, C.; Zhang, J.; Hu, C.; 95% CI = 1.608–45.859;course of more than 10 years, OR = 9.020, 95%CI = 1.854–43.892), multimorbid- Wang, Y.

Functional imaging studies consistently find that older adults recruit bilateral brain regions in cognitive tasks that are strongly lateralized in younger adults, a characterization known as the Hemispheric Asymmetry Reduction in Older Adults model. While functional imaging displays what brain areas are active during tasks, it cannot demonstrate what brain regions are necessary for task performance. We used behavioral data from acute stroke patients to test the hypothesis that older adults need both hemispheres for a verbal working memory task that is predominantly left-lateralized in younger adults. Right-handed younger (age 50, n = 7) and older adults (age > 50, n = 21) with acute unilateral stroke, as well as younger (n = 6) and older (n = 13) transient ischemic attack (TIA) patients, performed a self-paced verbal item-recognition task. Older patients with stroke to either hemisphere had a higher frequency of deficits in the verbal working memory task compared to older TIA patients. Additionally, the deficits in older stroke patients were mainly in retrieval time while the deficits in younger stroke patients were mainly in accuracy.

Voino-Yasenetsky Krasnoyarsk State Medical University, 660022 Krasnoyarsk, Russia * Correspondence: [email protected] Abstract: Neurogenesis is a key mechanism of brain development and plasticity, which is impaired in chronic neurodegeneration, including Parkinson’s disease. The accumulation of aberrant α-synuclein is one of the features of PD. Being secreted, this protein produces a prominent neurotoxic effect, alters synaptic plasticity, deregulates intercellular communication, and supports the development of neuroinflammation, thereby providing propagation of pathological events leading to the establish- ment of a PD-specific phenotype. Multidirectional and ambiguous effects of α-synuclein on adult neurogenesis suggest that impaired neurogenesis should be considered as a target for the prevention of cell loss and restoration of neurological functions. Thus, stimulation of endogenous neurogenesis or cell-replacement therapy with stem cell-derived differentiated neurons raises new hopes for the development of effective and safe technologies for treating PD neurodegeneration. Given the rapid development of optogenetics, it is not surprising that this method has already been repeatedly tested in manipulating neurogenesis in vivo and in vitro via targeting stem or progenitor cells.

Email: [email protected] Declarations of interest: none 1 1. Introduction A central question in cognitive aging research is how the evolution of cognitive functions with age is underpinned by changes of both brain structural characteristics and functional activity patterns. Neuroimaging studies revealed major findings associated with the effects of healthy aging on cognition, the impact of neurodegenerative disease, and variations between individuals. With aging, the brain undergoes several structural and functional changes (see Spreng & Turner, 2019, for a review). Brain structure consistently shows signs of grey matter atrophy and decreases in the microstructural integrity of white matter tracts connecting brain regions. Cortical activity, however, has been observed to either increase or decrease with age, depending on several task and population factors, suggesting either compensation, pathological under- or over-activation, or all of these (see Cabeza et al 2018; Stern et al.,

  • Older Adults with Lower Autobiographical Memory Abilities Report Less Age-Related Decline in Everyday Cognitive Function Carina L
    Fan et al. BMC Geriatrics (2020) 20:308 https://doi.org/10.1186/s12877-020-01720-7 RESEARCH ARTICLE Open Access Older adults with lower autobiographical memory abilities report less age-related decline in everyday cognitive function Carina L. Fan1,2* , Kristoffer Romero2 and Brian Levine1,2,3* Abstract Background: Individuals differ in how they remember the past: some richly re-experience specific details of past episodes, whereas others recall only the gist of past events. Little research has examined how such trait mnemonics, or lifelong individual differences in memory capacities, relate to cognitive aging. We specifically examined trait episodic autobiographical memory (AM, the tendency to richly re-experience episodic details of past events) in relation to complaints of everyday cognitive functioning, which are known to increase with age. Although one might predict that individuals reporting higher trait-level episodic AM would be resistant to age-related decline in everyday function, we made the opposite prediction. That is, we predicted that those with lower trait-level episodic AM would be better equipped with compensatory strategies, practiced throughout the lifespan, to cope with age-related memory decline. Those with higher trait-level episodic AM would have enhanced sensitivity to age-related cognitive changes due to their tendency to rely on their perceived above-average memory function. Methods: We tested these predictions in 959 older adults aged 50–93 using online subjective and objective measures of memory and cognitive function. Our key measures of interest were the Survey of Autobiographical Memory, a measure of autobiographical memory abilities; and the Cognitive Failures Questionnaire, a measure of everyday cognitive function.

  • Neuroscience and Well-Being by Sanda Dolcos, Matthew Moore, & Yuta Katsumi, University of Illinois at Urbana-Champaign
    Neuroscience and Well-Being By Sanda Dolcos, Matthew Moore, & Yuta Katsumi, University of Illinois at Urbana-Champaign Citation: Dolcos, S., Moore, M., & Katsumi, Y. (2018). Neuroscience and well-being. In E. Diener, S. Oishi, & L. Tay (Eds.), Handbook of well-being. Salt Lake City, UT: DEF Publishers. DOI:nobascholar.com Abstract: Abundant evidence highlights the important role of personality traits, age, and social relationships in the experience of subjective well-being. Experiential factors influence well-being, and evidence shows that specific forms of training, such as physical exercise and mindfulness meditation, can produce strong and enduring beneficial effects on well-being. These factors also shape the structure and function of our brains throughout the lifespan, with fascinating implications for our well-being. However, understanding how well-being is created (and changed) by our brains has only recently become the focus of neuroscientific investigations. In this chapter, we review recent neuroscientific evidence revealing how the neurocircuitries underlying personality traits (i.e., optimism, negative bias, self-esteem, extraversion, and neuroticism), successful emotional aging, and social relationships (i.e., love and loneliness) contribute to well-being, and how these circuits and systems are altered in chronic stress, anxiety, and depression. Identifying the neural correlates of well-being can illuminate the processes that cause higher levels of well- being, which, in turn, can inform promising training interventions that can induce neuroplastic changes and help people live happier, healthier, and more successful lives. Keywords: Affective biases, Neuroplasticity, Prefrontal cortex, Amygdala, Orbitofrontal cortex, Ventral striatum. The study of well-being has deep philosophical roots dating back to Aristotle, who proposed that well-being has at least two components: hedonia and eudaimonia (Aristotle, 2009; Seligman, Steen, Park, & Peterson, 2005).

According to “vascular hypothesis of cognitive aging,” community-dwelling older adults having risk factors for vascular disease development (RVD) may suffer from cognitive decline of the same type. The aim of the study was to assess the level of specific executive functions (EF) that have been revealed as most affected by vascular abnormalities, in older adults with incipient VaD and RVD. Subsequently specific ways of EF measuring could be suggested for more accurate diagnosis of early stage VaD. The study compared three adult groups (N = 60): (a) patients diagnosed with incipient VaD, according to DSM-5 criteria (n = 20); (b) Edited by: Ana B.
