“…To our knowledge, this is the first study to examine the association between level of perceived stress and neuropsychological test performance in a clinical sample of patients with work-related stress. However, Aggarwal et al (2014) found that higher levels of perceived stress were related to lower cognitive function as well as accelerated cognitive decline over nearly seven years of follow-up in a longitudinal population study of 6.207 older adults. It is possible that our negative results are a consequence of too little variability in perceived stress in this sample and therefore more studies with larger samples is needed to test this hypothesis further.…”

Patients on sick leave due to work-related stress often complain about impaired concentration and memory. However, it is undetermined how widespread these impairments are, and which cognitive domains are most long-term stress sensitive. Previous studies show inconsistent results and are difficult to synthesize. The primary aim of this study was to examine whether patients with work-related stress complaints have cognitive impairments compared to a matched control group without stress. Our secondary aim was to examine whether the level of self-reported perceived stress is associated with neuropsychological test performance. We used a broad neuropsychological test battery to assess 59 outpatients with work-related stress complaints (without major depression) and 59 healthy controls. We matched the patients and controls pairwise by sex, age and educational level. Compared to controls, patients generally showed mildly reduced performance across all the measured domains of the neuropsychological test battery. However, only three comparisons reached statistical significance (p < 0.05). Effect sizes (Cohen's d) were generally small to medium. The most pronounced differences between patients and controls were seen on tests of prospective memory, speed and complex working memory. There were no statistical significant associations between self-reported perceived stress level and neuropsychological test performance. In conclusion, we recommend that cognitive functions should be considered when evaluating patients with work-related stress complaints, especially when given advice regarding return to work. Since this study had a cross-sectional design, it is still uncertain whether the impairments are permanent. Further study is required to establish causal links between work-related stress and cognitive deficits.

“…Increased stress level are associated with rapid decline in cognitive function. 28 Moreover, cognitive decline may occur up to 30% faster in people prone to stress and distress, 29 and mnemonic functions may be mostly affected by high stress levels. 5 More specific studies have used oxidative stress markers to reveal this association.…”

.4% e pré-fragilidade de 52.9% nos idosos cuidadores. Cuidadores severamente sobrecarregados ou frágeis apresentaram pior desempenho cognitivo comparado àqueles levemente sobrecarregados e não frágeis, respectivamente (teste ANOVA). Apresentar simultaneamente sobrecarga elevada e algum grau de fragilidade (pré-frágil ou frágil) esteve associado à redução do desempenho cognitivo global. Conclusão: Um significante número de idosos cuidadores teve indício de alteração cognitiva. Estratégias e recursos para reduzir o sentimento de sobrecarga e a fragilidade física podem melhorar o desempenho mental e o bem estar, levando assim a uma melhora da qualidade de vida do idoso que cuida, bem como a qualidade do cuidado prestado por ele. Descritores: Cuidado a idosos, cuidadores, idoso frágil, cognição, população rural. AbstractIntroduction: Older caregivers living in rural areas may be exposed to three vulnerable conditions, i.e., those related to care, their own aging, and their residence context. Objective: To analyze the association of burden and frailty with cognition performance in older caregivers in rural communities. Method: In this cross-sectional survey, 85 older caregivers who cared for dependent elders were included in this study. Global cognition (Addenbrooke's Cognitive Examination -Revised; Mini Mental State Examination), burden (Zarit Burden Interview) and frailty (Fried's frailty phenotype) were assessed. All ethical principles were observed. Results: Older caregivers were mostly women (76.7%); mean age was 69 years. Cognitive impairment was present in 15.3%, severe burden in 8.2%, frailty in 9.4%, and pre-frailty in 52.9% of the older caregivers. More severely burdened or frail caregivers had worse cognitive performance than those who were not, respectively (ANOVA test). Caregivers presenting a high burden level and some frailty degree (pre-frail or frail) simultaneously were more likely to have a reduced global cognition performance. Conclusion: A significant number of older caregivers had low cognitive performance. Actions and resources to decrease burden and physical frailty may provide better cognition and well-being, leading to an improved quality of life and quality of the care provided by the caregivers. Keywords: Aged care, caregivers, frail elderly, cognition, rural population. Cognition, burden and frailty in rural caregivers -Brigola et al.

“…Middle aged adults who were categorized as reporting consistently high levels of stress across each of the three assessment occasions, reported greater declines in subjective cognition compared to those who were categorized as reporting consistently low levels of stress (Rönnlund et al, 2013). Among older adults, Aggarwal and colleagues (2014) reported that greater baseline perceived stress was associated with impaired cognitive function as well as with cognitive decline across a six year period.…”

Research on stress and cognitive aging has primarily focused on examining the effects of biological and psychosocial indicators of stress with little attention provided to examining the association between perceived stress and cognitive aging. We examined the longitudinal association between global perceived stress (GPS) and cognitive change among 116 older adults (Mage = 80, SD = 6.40, range: 67–96) in a repeated measurement burst design. Bursts of six daily cognitive assessments were repeated every six months over a two-year period with self-reported GPS assessed at the start of every burst. Using a double-exponential learning model, two parameters were estimated: 1) asymptotic level (peak performance), and 2) asymptotic change (the rate in which peak performance changed across bursts). We hypothesized that greater GPS would predict slowed performance in tasks of attention, working memory, and speed of processing and that increases in GPS across time would predict cognitive slowing. Results from latent growth curve analyses were consistent with our first hypothesis and indicated that level of GPS predicted cognitive slowing across time. Changes in GPS did not predict cognitive slowing. This study extends previous findings by demonstrating a prospective association between level of GPS and cognitive slowing across a two-year period highlighting the role of psychological stress as a risk factor for poor cognitive function.
