“…Emotional expressivity may be protective when individuals are at increased risk of dementia due to poor written language skills (i.e., when idea density is low), but detrimental when not at increased risk (i.e., when idea density is high). This is consistent with other studies that show the importance of context when considering the protective effect of intellectual factors on cognitive impairment, such as evidence that cognitively demanding skills (e.g., multilingualism) may be protective when individuals are at increased risk of poor cognitive outcomes due to low levels of education [ 16, 19, 45 ] or other cognitive leisure activities [ 18 ].…”

Background: Risk factors for dementia, such as Alzheimer’s disease, are complex and span a lifetime. Exploring novel factors, such as characteristics of writing, may provide insight into dementia risk. Objective: To investigate the association between emotional expressivity and risk of dementia in the context of a previously identified risk factor, written language skills. Methods: The Nun Study recruited 678 religious sisters aged 75 + years. Of these, 149 U.S.-born participants had archived autobiographies handwritten at a mean age of 22 years. The autobiographies were scored for frequency of emotion word usage and language skills (e.g., idea density). The association of emotional expressivity and a four-level composite variable (combining high/low emotional expressivity and high/low idea density) with dementia was assessed using logistic regression models adjusted for age, education, and apolipoprotein E. Results: Within the composite variable, odds of dementia increased incrementally, with opposing effects of emotional expressivity across the two idea density levels. Compared to the referent category (low emotional expressivity/high idea density), the risk of dementia increased in those with high emotional expressivity/high idea density (OR = 2.73, 95% CI = 1.05–7.08), while those with low emotional expressivity/low idea density had the highest risk (OR = 18.58, 95% CI = 4.01–86.09). Conclusion: Dementia risk is better captured by inclusion of multiple measures relating to characteristics of writing. Emotional expressivity may be protective when individuals are at increased risk due to poor written language skills (i.e., low idea density), but detrimental when not at risk (i.e., high idea density). Our findings indicate that emotional expressivity is a contextually-dependent novel risk factor for dementia.

“…Research has demonstrated a bidirectional relationship between them, meaning that difficulty sleeping is not just a symptom of depression but a predictable precursor symptom (Fang et al, 2019). Among environmental factors, social support availability showed a negative correlation with dyspnea when lying down, indicating that individuals experiencing dyspnea may prioritize symptom management over participating in social activities (Quick et al, 2022).…”

BackgroundSomatic symptoms and related factors in patients with chronic heart failure have been extensively researched. However, more insight into the complex interconnections among these constructs is needed, as most studies focus on them independently from each other.AimsThe aim of this study is to gain a comprehensive understanding of how somatic symptoms and related factors are interconnected among patients with chronic heart failure.MethodsA total of 379 patients were enrolled. Network analysis was used to explore the interconnections among the somatic symptoms and related risk factors.ResultsThe four core symptoms of chronic heart failure were daytime dyspnea, dyspnea when lying down, fatigue and difficulty sleeping. Within the network, the edge weights of depression–anxiety, subjective social support–objective social support, and subjective social support–social support availability were more significant than others. Among physiological, psychological and environmental factors, the edge weights of NYHA–dyspnea, depression–difficulty sleeping, and social support availability–dyspnea when lying down were more significant than others. Depression and anxiety had the highest centrality, indicating stronger and closer connections with other nodes.ConclusionsPsychological and environmental factors stood out in the network, suggesting the potential value of interventions targeting these factors to improve overall health.
