Destination memory disorders: At the junction between memory and socioaffective processing.

The junction between memory dysfunction and socioaffective dysfunction is a complex area as research has typically been interested in one dysfunction rather than in the other. However, this junction can be studied under the lens of destination memory. Destination memory (i.e. the ability to remember to whom a piece of information was previously transmitted) is unique in that it draws on both memory and socioaffective processes. Research has demonstrated how destination memory is prone to distortions in neurological/psychiatric disorders. This paper aims to provide a focused review on the interplay between memory and socioaffective processes in the deterioration of destination memory within these disorders. It shows how both episodic memory and socioaffective dysfunction can jointly contribute to the decline in destination memory, although the contribution of each of the two factors may vary depending on the disorder.

An internet-based cognitive behavioural intervention for adults with depression in Arabic-speaking countries: A randomized controlled trial.

Internet-based interventions have proven to be effective for the treatment of depression in different samples, but evidence from the Middle East and North Africa (MENA) region is scarce. The aim of this study was to investigate the acceptance and efficacy of an internet-based cognitive behavioural writing intervention for Arabic-speaking participants with depression living in the MENA region. A total of 259 participants (167 female, age in years: M = 25.58, SD = 6.39) with depressive symptoms indicative of clinical relevance were randomly allocated to a treatment group (TG; nTG = 128) or a waitlist control group (WG; nWG = 131). The TG received an internet-based intervention over a 6-week period. The primary outcome was depressive symptoms, and secondary outcomes were anxiety and quality of life (QoL). T-tests with change scores from pre- to post-treatment were used for data analyses. Intention-to-treat (ITT) as well as completer analyses were calculated. The ITT analysis revealed significant differences between the TG and WG in depression (T257 = -4.89, p < 0.001, d = 0.70) and QoL (T257 = 3.39, p < 0.001, d = 0.47). Significant differences regarding anxiety symptoms (T257 = 3.25, p < 0.05, d = 0.53) were identified for the completer sample. The general dropout rate was 39.9%. The results indicate the feasibility and efficacy of an internet-based cognitive behavioural writing intervention in adults from Arabic-speaking countries. The development and implementation of such interventions can be used to improve access to psychological help and adequate treatment.

In the Eyes of the Future: Eye Movement during Near and Distant Future Thinking.

Research has suggested that near future events are typically viewed from a first-person (an own-eyes, also known as field) perspective while distant future events are typically viewed from a third-person (an observer) perspective. We investigated whether these distinct mental perspectives would be accompanied by distinct eye movement activities. We invited participants to imagine near and distant future events while their eye movements (i.e., scan path) were recorded by eye-tracking glasses. Analysis demonstrated fewer but longer fixations for near future thinking than for distant future thinking. Analysis also demonstrated more "field" mental visual perspective responses for near than for distant future thinking. The long fixations during near future thinking may mirror a mental visual exploration involving processing of a more complex visual representation compared with distant future thinking. By demonstrating how near future thinking triggers both "field" responses and long fixations, our study demonstrates how the temporality of future thinking triggers both distinct mental imagery and eye movement patterns.

Sex and gender differences in risk factors for posttraumatic stress disorder: A systematic review and meta-analysis of prospective studies.

Women are at higher risk than men for developing posttraumatic stress disorder (PTSD), but underlying mechanisms are still unclear. Comprehensive knowledge about these mechanisms is necessary to develop tailored, sex- and gender-sensitive preventive interventions. This systematic review and meta-analysis examined sex-/gender-dependent risk factors, that is, risk factors with sex/gender differences in (a) vulnerability or (b) prevalence/severity, as well as sex-/gender-specific risk factors, that is, and (c) risk factors present in one sex/gender only. We searched PubMed, Web of Science, PsycINFO, PsycArticles, and PSYNDEX for articles published until October 16, 2022. We included prospective studies that assessed risk factors to predict subsequent PTSD symptom severity, as measured with the Clinician-Administered PTSD scale. The primary outcomes were sex/gender stratified pooled for sex-/gender-dependent vulnerability and sex-/gender-specific risk factors and pooled odds ratio (OR) or standardized mean difference (SMD) for sex-/gender-dependent risk factor prevalence/severity. We screened 17,270 records and included 117 reports from 45 studies (N = 13,752) in the systematic review. Seventeen studies (N = 4,257; 1,827 women, 2,430 men) were included in the meta-analysis. Regarding risk factor vulnerability, analyses revealed no significant sex/gender differences except for acute stress symptoms, with stronger associations for men (b = 0.11, SE = 0.06, p < .05). Regarding risk factor prevalence/severity, women reported more severe immediate psychological stress responses (range SMD = 0.23-0.56) and more commonly had a history of mental illness (OR = 1.81, 1.27-2.58). Men showed higher trauma load (SMD = -0.15, -0.29 to 0.01). Few women-specific and no men-specific factors were identified. Results suggest that women's heightened immediate psychological stress response drives sex/gender disparities in PTSD symptom severity. Preventive interventions should thus target women early after trauma. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Beauty and Paintings: Aesthetic Experience in Patients with Behavioral Variant Frontotemporal Dementia When Viewing Abstract and Concrete Paintings.

We assessed the aesthetic experience of patients with behavioral variant frontotemporal dementia (bvFTD) to understand their ability to experience feelings of the sublime and to be moved when viewing paintings. We exposed patients with bvFTD and control participants to concrete and abstract paintings and asked them how moved they were by these paintings and whether the latter were beautiful or ugly. Patients with bvFTD declared being less moved than control participants by both abstract and concrete paintings. No significant differences were observed between abstract and concrete paintings in both patients with bvFTD and control participants. Patients with bvFTD provided fewer "beautiful" and more "ugly" responses than controls for both abstract and concrete paintings. No significant differences in terms of "beautiful" and "ugly" responses were observed between abstract and concrete paintings in both patients with bvFTD and control participants. These findings suggest disturbances in the basic affective experience of patients with bvFTD when they are exposed to paintings, as well as a bias in their ability to judge the aesthetic quality of paintings.

The phenomenological experience of autobiographical memory in patients with behavioral-variant frontotemporal dementia.

In this study, we offer a comprehensive assessment of the phenomenological experience of patients with behavioral-variant frontotemporal dementia (bvFTD) upon retrieval of autobiographical memory. We invited patients with bvFTD and control participants to retrieve autobiographical memories and rate, for each memory, its phenomenological characteristics. We also analyzed the retrieved memories regarding specificity (i.e., whether the memory described a general or a detailed event). Results demonstrated that, compared to control participants, patients with bvFTD attributed lower levels of reliving, back in time (feeling as if going back in time), remembering, realness, visual imagery, auditory imagery, language, emotion, rehearsal, importance, spatial recall and temporal recall to their memories. Lower autobiographical specificity was also observed in patients with bvFTD compared to control participants. Autobiographical specificity in patients with bvFTD was associated with verbal fluency and verbal episodic memory, but not with phenomenological experience. Although autobiographical memories of patients with bvFTD show low ratings of phenomenological experience, the patients may still enjoy some limited subjective experience during autobiographical retrieval.

Limited awareness of hallucinations in patients with Alzheimer's disease.

INTRODUCTION: We investigated the degree of cognitive insight in patients with Alzheimer's Disease (AD) regarding their hallucinations, aiming to elucidate the subjective experiences and perceptions associated with this phenomenon. METHODS: Using a cross-sectional design, we invited both AD patients (n = 31) and their informants to evaluate the occurrence of hallucinations. Degree of cognitive insight was based upon the discrepancy between the patients' and informants' evaluations. RESULTS: Analysis demonstrated that AD patients rated the occurrence of hallucinations lower than their informants, indicating that patients tended to underestimate the frequency of their hallucinations. The discrepancy between the ratings of patients and informants was negatively correlated with cognitive functioning, suggesting that a greater discrepancy (indicating poorer insight) was associated with lower cognitive functioning in patients. DISCUSSION: Our findings highlight the deficits in insight into hallucinations among AD patients, specifically indicating that AD patients have limited awareness of their own hallucinations. Furthermore, our findings support the idea that deficits in insight into hallucinations are associated with the progression of AD.

[Faisabilité de l'exploration des fonctions exécutives des résidents d'établissement d'hébergement pour personnes âgées]. / Feasibility of exploring executive functions in long-term care residents, the Screening Executive Tests for Elderly.

Impairment of cognitive functions is the primary reason for admission to long-term care units, with executive functions playing a pivotal role in dependency and behavioral issues. These functions pose significant challenges to nursing staff in providing care. However, the assessment of executive functions in elderly individuals residing in nursing homes often relies on tests that are both time-consuming and difficult for this demographic. In many instances, executive functions are either not assessed or only examined in broad terms. OBJECTIVE: The objective of this study was to analyze the feasibility of assessing executive functions in elderly nursing home residents, specifically aiming to distinguish sub-components such as mental flexibility, working memory, planning, and inhibition. The residents included in the study underwent executive function assessments over three visits, using various tests for each sub-component. METHODS: Out of 530 residents, 46 gave their consent and 38 completed the three visits, with an average age of 90±5 years (76.2% women) and a median MMSE score of 20/30. Feasibility was evaluated based on the test being executed and the frequency of interruptions due to difficulty or fatigue on the part of the resident. RESULTS: Only four tests proved suitable for elderly individuals in nursing homes, and we propose grouping them into a battery named SETE (Screening Executive Tests for Elderly): the conflicting instructions from the FAB, the alpha test, the clock test, and the verbal span test. CONCLUSION: The use of these four tests would enable the construction of a map delineating executive function impairment by sub-component. Enhanced knowledge of executive functions in long-term care residents will facilitate better adapted dependency management and the implementation of non-pharmacological interventions for behavioral disorders.

Changes in trauma appraisal during brief internet-based exposure and cognitive restructuring treatment for Arabic-speaking people with PTSD.

Background: Maladaptive trauma appraisal plays an important role in the development and maintenance of posttraumatic stress disorder (PTSD). While studies have demonstrated the effectiveness of exposure and cognitive treatments for PTSD symptomatology, the effect of such treatments on specific trauma appraisals is still not well understood.Objective: The study investigated the effect of an exposure and a cognitive restructuring internet-based treatment on specific trauma appraisals in Arabic-speaking participants with PTSD.Method: 334 participants received either an exposure (n = 167) or a cognitive restructuring (n = 167) internet-based treatment. PTSD symptom severity (PCL-5) and specific trauma appraisals (TAQ) were assessed at pre- and post-treatment. Changes in specific trauma appraisals within and between the two treatments were analyzed using multi-group change modelling. Associations between changes in PTSD symptom severity and changes in trauma appraisals were evaluated using Pearson product-moment correlation. For both treatments, participants with versus without reliable improvement were compared regarding changes in specific trauma appraisals using Welch tests. Analyses were performed on 100 multiple imputed datasets.Results: Both treatments yielded significant changes in shame, self-blame, fear, anger, and alienation (all ps < .001). Changes in betrayal were only significant in the cognitive restructuring treatment (p < .001). There was no evidence of differences between treatments for any specific trauma appraisal. Changes in PTSD symptom severity were significantly associated with changes in trauma appraisals (all ps < .001). In both treatments, participants who experienced reliable improvement in PTSD symptom severity showed significantly larger pre- to post-treatment changes in specific trauma appraisals compared to those without reliable improvement. Again, differences in betrayal were only significant in the cognitive restructuring treatment.Conclusions: The findings indicate that both treatments are effective in reducing trauma appraisals in Arabic-speaking people with PTSD. Changes in trauma appraisal seem to be associated with changes in PTSD symptomatology.Trial registration: German Clinical Trials Register identifier: DRKS00010245.

Exposure and cognitive restructuring treatment in Arabic-speaking individuals with PTSD yield significant changes in shame, self-blame, fear, anger, and alienation.Changes in PTSD symptoms are positively associated with changes in specific trauma appraisals.There is no evidence of differences between both treatments for any specific trauma appraisal.

ChatGPT as a Diagnostic Aid in Alzheimer's Disease: An Exploratory Study.

Background: The potential of ChatGPT in medical diagnosis has been explored in various medical conditions. Objective: We assessed whether ChatGPT can contribute to the diagnosis of Alzheimer's disease (AD). Methods: We provided ChatGPT with four generated cases (mild, moderate, or advanced stage AD dementia, or mild cognitive impairment), including descriptions of their complaints, physical examinations, as well as biomarker, neuroimaging, and neuropsychological data. Results: ChatGPT accurately diagnosed the test cases similarly to two blinded specialists. Conclusions: While the use of generated cases can be a limitation to our study, our findings demonstrate that ChatGPT can be a useful tool for symptom assessment and the diagnosis of AD. However, while the use of ChatGPT in AD diagnosis is promising, it should be seen as an adjunct to clinical judgment rather than a replacement.

On hallucinations and memory: the relationship between hallucinations and autobiographical overgenerality in Alzheimer's Disease.

OBJECTIVES: Alzheimer's disease (AD) has been associated with autobiographical overgenerality (i.e. a tendency of patients to retrieve general rather than specific personal memories). AD has also been associated with hallucinations. We investigated the relationship between autobiographical overgenerality and hallucinations in AD. METHODS: We invited 28 patients with mild AD to retrieve autobiographical memories, and we also evaluated the occurrence of hallucinations in these patients. RESULTS: Analysis demonstrated significant correlations between hallucinations and autobiographical overgenerality in the patients. CONCLUSION: AD patients who are distressed by hallucinations may demonstrate autobiographical overgenerality as a strategy to avoid retrieving distressing information that may be related with hallucinations. However, hallucinations as observed in our study can be attributed to other factors such as the general cognitive decline in AD.

When you look at your past: Eye movement during autobiographical retrieval.

Until recently, little was known about whether or how autobiographical memory (i.e., memory of personal information) activates eye movement. This issue is now being addressed by several studies demonstrating not only how autobiographical memory activates eye movement, but also how eye movement influences the characteristics of autobiographical retrieval. This paper summarizes this research and presents a hypothesis according to which fixations and saccades during autobiographical retrieval mirror the construction of the visual image of the retrieved event. This hypothesis suggests that eye movements during autobiographical retrieval mirror the attempts of the visual system to generate and manipulate mental representations of autobiographical retrieval. It offers a theoretical framework for a burgeoning area of research that provides a rigorous behavioral evaluation of the phenomenological experience of memory.

"Do not take that medication": negative prospective memory in Korsakoff's syndrome.

BACKGROUND: While prospective memory (i.e., the ability to execute a future plan) has been extensively researched, little is known about negative prospective memory (i.e., the ability to remember not to execute a future plan) in Korsakoff's syndrome (KS). We thus evaluated both prospective memory and negative prospective memory in KS, as well as the relationship between both types of prospective memory and inhibition. METHODS: Patients with KS and control participants were invited to press a button on the keyboard (i.e., prospective memory) or not to press a button when a cue word (e.g., negative prospective memory) was encountered. RESULTS: The analysis demonstrated that patients with KS had more prospective memory errors (i.e., forgetting to click the keyboard when the instruction was to do so) than control participants. The analysis also demonstrated that patients with KS had more negative prospective memory errors (i.e., clicking the keyboard when the instruction was not to do so) than control participants. Similar levels of commissions and omissions were observed in patients with KS than in control participants. Interestingly, prospective and negative prospective performances were significantly correlated with performance on an inhibition assessment task. DISCUSSION: Our study demonstrates that KS is characterized by not only difficulty in remembering to execute a future intention but also by difficulty in remembering not to execute a future intention. A decline in negative prospective memory in KS can be associated with difficulty in inhibiting no longer appropriate previously learned intentions.

Relationship Between Future Thinking and Prospective Memory in Alzheimer's Disease.

Background: Future thinking and prospective memory are two cognitive processes oriented toward the future and reliant on the ability to envision oneself in future scenarios. Objective: We explored the connection between future thinking and prospective memory in individuals with Alzheimer's disease (AD). Methods: We invited both AD participants and control participants to engage in event-based prospective memory tasks (e.g., "please hand me this stopwatch when I inform you there are 10 minutes remaining") and time-based prospective memory tasks (e.g., "close the book you are working on in five minutes"). Additionally, we asked participants to engage in a future thinking task where they imagined upcoming events. Results: Analysis revealed that AD participants exhibited lower performance in both prospective memory tasks and future thinking compared to the control group. Importantly, we identified significant positive correlations between the performance on event- and time-based prospective memory tasks and future thinking abilities among AD participants. Conclusions: These findings underscore the connection between the decline in both prospective memory domains and the ability to envision future events in individuals with AD. Our results also shed light on the challenges AD individuals face when trying to project themselves into the future to mentally pre-experience upcoming events.

The guaranteed euros: Probabilistic discounting in behavioural-variant frontotemporal dementia.

Financial decision-making requires trading off between guaranteed and probabilistic outcomes and between immediate and delayed ones. While research has demonstrated that patients with behavioural-variant frontotemporal dementia (bvFTD) prefer immediate rewards at the expense of future ones (i.e. temporal discounting), little is known about how patients choose between smaller, guaranteed and larger, but probabilistic, outcomes (i.e. probabilistic discounting). We thus investigated probabilistic discounting by inviting 18 patients with bvFTD and 20 control participants to choose between fixed smaller monetary amounts and a fixed larger monetary amount with a variated probability of occurrence (e.g. 'Would you rather have 40€ for sure or a 20% chance of winning 100€?'). Results demonstrated lower scores, indicating higher risk tolerance, on the probabilistic discounting task in patients with bvFTD (while impulsively choosing more immediate rewards on the temporal discounting task) compared to control participants. Probabilistic discounting was significantly correlated with a decline in general cognitive performance in patients with bvFTD. When dealing between smaller, guaranteed, and larger, but probabilistic, rewards, patients with bvFTD tend to prefer guaranteed rewards and discount the uncertain ones.

Déjà vu and involuntary autobiographical memories as two distinct cases of familiarity in patients with Alzheimer's disease.

The continuum between involuntary autobiographical memories and déjà vu, as proposed by Barzykowski and Moulin, can be better defined by considering research on autobiographical retrieval in patients with Alzheimer's disease. Although autobiographical retrieval in patients with Alzheimer's disease can generally be associated with a sense of familiarity, involuntary retrieval can trigger an autonoetic experience of retrieval in these patients.

ChatGPT's dance with neuropsychological data: A case study in Alzheimer's disease.

Artificial intelligence continues to revolutionize the medical and scientific field, especially with the release of ChatGPT. We assessed whether it provides an accurate interpretation of neuropsychological screening. We provided ChatGPT with the neuropsychological data of a patient with mild Alzheimer's Disease and invited it and two neuropsychologists to interpret the data. While ChatGPT provided an accurate interpretation of scores on each of the neuropsychological tests, it did not use standardized scores and did not specify the cognitive domain that may be most impaired. In contrast, the neuropsychologists used standardized scores to determine that the patient was mainly suffering from memory decline. While ChatGPT may succeed in the general interpretation of neuropsychological testing, at least in patients with Alzheimer's Disease, it still cannot create a pattern of scores across different tests to better specify the nature of cognitive impairment.

The neutral past: emotional (dys)regulation of autobiographical memory in behavioural variant frontotemporal dementia.

BACKGROUND: While affective disturbances are a key symptomatic indicator of behavioural variant frontotemporal dementia (bvFTD), little is known about how patients process the emotional load of their autobiographical (i.e. personal) memories. METHODS: We assessed the interplay of emotional regulation and autobiographical memory by inviting 18 bvFTD and 20 control participants to remember past personal events. For each memory, participants rated its emotional valence "then" (i.e. when the event has occurred) vs "now" (i.e. when retrieving the event). RESULTS: Patients with bvFTD described their memories as neutral at both times (p = .85), while control participants rated their memories as more positive during "then" than during "now" (p = .013). Autobiographical retrieval triggered fewer emotional words (p < .001) and less specificity (p < .001) in bvFTD patients compared to control participants. CONCLUSIONS: The lack of significant differences between the emotional characteristics during "then" than "now" in patients with bvFTD (and the flattening of both) may mirror their hampered ability for emotional generation, which may be associated with difficulties in reframing their past experiences to modify and adapt their meaning. The hampered emotional regulation in bvFTD may also be associated with an avoidance strategy and a passive attitude toward the past.

Memory in Social Interactions: The Effects of Introspection on Destination Memory in Traumatic Brain Injury.

Destination memory, which is the ability to remember to whom one has sent information, is intimately associated with social cognition. We assessed whether processing attributes of destinations would improve destination memory in patients with traumatic brain injury (TBI). In this cross-sectional study, we tested the destination memory of 24 patients with TBI and 25 control participants in two conditions. On the first one (control condition), we invited participants to tell proverbs to celebrities' faces in order to decide, on a subsequent recognition test, whether they previously told that proverb to that celebrity or not. On the second condition (experimental introspection condition), the same procedures were repeated. However, after telling the proverbs, we invited participants to introspect about what the destination might believe about the proverbs (e.g., "What do you think that the celebrities would think about the proverbs?"). Group comparisons demonstrated better destination memory after the introspection than when no introspection was implemented in control participants, but there were no significant differences between the two conditions in patients with TBI. However, analyses of individual profiles demonstrated that more than half (n = 13) of the patients with TBI demonstrated better destination memory after introspection. While these results demonstrate a beneficial effect of introspection on destination memory for some cases of patients with TBI, more research is needed to reveal how introspection may influence patients' memory in social interactions.
