“…The second mechanism concerns the patient–carer relationship. Given that married couples are often of similar cognitive and intelligence levels (Caillot‐Ranjeva et al., 2021; Mascie‐Taylor, 1989; Watson et al., 2004), our more intelligent participants would have similarly intelligent spouses who, in turn, may potentially have rated them more harshly than the spouses of less intelligent patients owing to their related critical thinking abilities. Third, our results may indicate either that the patients or their family members were unable to express degrees of behavioral abnormality adequately or that we, at present, lack the sufficient measurement tools.…”

Loss of “insight” into behavioral changes in ALS: Differences across cognitive profiles

Objective: Behavioral impairment occurs in amyotrophic lateral sclerosis (ALS) and ALS-fronto-temporal dementia (ALS-FTD). It has been proposed that ALS patients without FTD retain an awareness of their behavioral impairment while ALS-FTD patients lose this awareness (referred to as retention vs. loss of "insight"). Loss of insight has not yet been studied across the entire ALS-FTD spectrum; our study addresses this gap by including patients with all the ALS cognitive-behavioral profiles.Methods: Eighty-three ALS patients (and their informants) took part in this bicentric study involving two German recruitment sites. Patients and informants completed the Frontal Systems Behavior Scale covering the domains of apathy, disinhibition, and executive dysfunctioning. Patients were classified into five groups according to the Strong and Rascovsky criteria: cognitively unimpaired (ALSni), cognitively impaired without dementia (ALSci), behaviorally impaired (ALSbi), a combination of behaviorally and cognitively impaired (ALScbi), and ALS-FTD. We applied Bayesian two-way ANOVA to test whether there were subgroup differences regarding insight into their behavioral decline.Results: All patient subgroups experienced behavioral decline (Bayes factor > 3). Only ALS-FTD patients lost insight into disinhibition and executive dysfunctioning. ALSbi patients exhibited worse insight than ALSni and ALSci patients (Bayes factor > 10). Evidence regarding the ALScbi patients was inconclusive. Higher IQ was associated with worse insight (Bayes factor > 3). Conclusions:Our findings provide solid support for the notion that ALS patients without dementia experience behavioral decline regardless of their cognitive-behavioral profile and retain different levels of insight into this decline. The inverse association of premorbid verbal intelligence with insight was unexpected, leaving room for further investigation.

“…Toutefois, nous observons aussi, parmi les vrais couples, une similarité des performances de fluence verbale non seulement entre conjoints d'âge et niveau d'éducation homogènes mais aussi entre conjoints d'âge et niveau d'étude hétérogènes, un résultat en faveur de l'hypothèse selon laquelle les interactions relationnelles et verbales au quotidien expliquent aussi la similarité des performances. Ainsi, les deux phénomènes (assortative mating et interactions relationnelles) contribueraient à cette similarité cognitive au sein des couples [8]. Un regard particulier pourra également être porté sur un éventuel effet genre-dépendant.…”

“…Another study reported that elderlies without a spouse are more vulnerable to depression in social life relative to those with a spouse [ 18 ]. In addition, there is empirical evidence that elderly couples have similarities in cognitive functions (e.g., lexicosemantic) because of the mutual influence between them [ 19 ]. Elderly couples also experience more enjoyment and less anxiety during social interactions with their spouse [ 20 , 21 ].…”

Interpersonal Competition in Elderly Couples: A Functional Near-Infrared Spectroscopy Hyperscanning Study

et al. 2023

View full text Add to dashboard Cite

Elderly people tend not to compete with others, and if they do, the mechanism behind the competition is not clear. In this study, groups of elderly couples and matched cross-sex controls were recruited to perform a competitive button-pressing task, while their brain signals were simultaneously collected using functional near-infrared spectroscopy (fNIRS) hyperscanning. Several fundamental observations were made. First, controls showed attenuated interpersonal competition across task processes, but couples held the competition with each other. Second, couples demonstrated increased inter-brain synchronization (IBS) between the middle temporal cortex and the temporoparietal junction across task processes. Third, Granger causality analysis in couples revealed significant differences between the directions (i.e., from men to women, and from women to men) in the first half of the competitive task, whereas there was no significant difference in the second half. Finally, the groups of couples and controls could be successfully discriminated against based on IBS by using a machine-learning approach. In sum, these findings indicate that elderly couples can maintain interpersonal competition, and such maintenance might be associated with changes in the IBS of the mentalizing system. It suggests the possible positive impact of long-term spouse relationships on interpersonal interactions, both behaviorally and neurally, in terms of competition.
