Emotion recognition is impaired in dementia and there is some initial evidence to suggest that milder deficits may be present in Mild Cognitive Impairment (MCI) patients, an "at risk" population for transition to dementia. In this study, we investigated the emotion recognition profile of MCI subgroups. Results show emotion recognition deficits exist for the amnestic subtype with impairment in multiple domains, with an emotion-specific deficit for anger recognition. Impaired emotion recognition in aMCI was independent of patient mood and cognitive deficits. The study is the first to examine the nonamnestic subtype. No emotion recognition deficits were found. This finding is surprising given the association between the nonamnestic subtype and frontal systems dysfunction. Impaired emotion recognition could be related to the selective pathophysiology in neural pathways, particularly the temporal lobe and connected limbic and prefrontal regions, implicated in both aMCI and emotion processing. These findings may have implications for early diagnosis, prognosis, and clinical management.
Background: Individuals living with Alzheimer’s disease (AD) demonstrate extensive deficits in social cognition. To date, no studies have investigated the feasibility of an intranasal oxytocin (INOT) treatment to improve social cognition in individuals living with AD. Objective: We conducted a pilot trial to determine recruitment feasibility, enrolment acceptability, and adherence to an INOT treatment to inform on the subsequent design of a future randomized controlled trial (RCT). We also estimated the effect sizes of potential social cognitive function outcome measures related to participants and their caregivers. Methods: Four individuals with AD were enrolled in a single-center, randomized, double-blind, placebo-controlled crossover trial involving a one-week treatment period with both INOT (72 IU twice daily) and placebo. Results: All participants reported no treatment-causative or serious adverse events following repeated INOT administration. While enrolment acceptability (100%) and INOT adherence (placebo, 95%; INOT, 98%) were excellent, feasibility of recruitment was not acceptable (i.e., n = 4/58 individuals screened met inclusion criteria). However, positive/large effects were associated with secondary outcomes of self-reported health and wellbeing, caregiver ‘burden’, intimacy and interpersonal-bonding, following repeated INOT administration. No positive effects were associated with participant outcomes of social cognition. Conclusion: This pilot RCT provides first evidence that INOT administration in individuals living with AD is safe and well-tolerated. Despite limitations in sample size, moderate-to-large effect size improvements were identified in participant health outcomes as well as core social cognitive functions and ‘burden’ as reported by a caregiver. This suggests potential broad-ranging beneficial effects of INOT which should be assessed in future RCTs.
Objective: The primary aim of this research was to explore the relationship between burnout and depression among Australian psychologists, and to investigate the role of self-compassion in this relationship.Method: A sample of 248 psychologists (average 41 years old; 81.1% female) currently working in Australia completed an on-line survey including measures of burnout (Copenhagen Burnout Inventory), depression (Depression Anxiety Stress Scale), and self-compassion (Self-Compassion Scale – Short Form).Results: In total 69 psychologists (27.8%) met criteria for burnout, while 42 (16.9%) reported at least mild depressive symptoms. Burnout and depression were significantly associated with each other (r = .44), while negative medium associations were found between self-compassion and burnout and depression (r = .48), respectively. A hierarchical regression analysis revealed self-compassion moderated the relationship between burnout and depression; psychologists with high levels of burnout and low to moderate levels of self-compassion reported significantly higher levels of depressive symptoms.Conclusions: The current results indicate that self-compassion may act as a protective factor against the effects of depression and burnout. Given elevated burnout and depressive symptoms reported by Australian psychologists, the development and promotion of self-compassion focused self-care practices for psychologists may be beneficial and warrants further research.KEY POINTSWhat is already known about this topic: Burnout and depression are highly prevalent among psychologists.Self-compassion is associated with enhanced psychological health and well-being.Self-compassion can buffer against negative states.What this topic adds: Psychologists who are more self-compassionate experience lower levels of burnout and depressive symptoms.For psychologists with high levels of burnout, the practice of self-compassion can significantly lower the severity of depressive symptoms experienced.Self-compassion may be a useful self-care tool to reduce psychological distress.
Abstract Objectives: Older adults presenting with mild cognitive impairment (MCI) have a higher risk of developing dementia and also demonstrate impairments in social cognition. This study sought to establish whether in people with MCI, poorer theory of mind (ToM) was associated with volumetric changes in the amygdala and hippocampus, as well as early changes in behaviour. Methods: One hundred and fourteen people with MCI and fifty-two older adult controls completed the Reading the Mind in the Eyes Test (RMET), while close informants (e.g., spouse/family member/friend/carer) described any current behavioural changes using the Revised Cambridge Behavioural Inventory (CBI-R). A subsample of participants completed structural magnetic resonance imaging (MRI). Results: The MCI group showed poorer performance on all neuropsychological tests administered, and moderate reductions on the RMET compared to the control group ( d = .44), with greater reduction observed in those with amnestic compared to non-amnestic MCI ( p = .03). While a robust correlation was identified between poorer RMET performance and smaller hippocampal volume in the control group ( ρ = .53, p = .01), this relationship was not apparent in the MCI group ( ρ = .21, p = .11). In the MCI group, poorer RMET performance was associated with poorer everyday skills ( ρ = −.26, p = .01) assessed by the CBI-R. Conclusions: Our findings cross-validate previous reports that social cognitive deficits in ToM are a feature of MCI and also suggest that disruptions to broader neural networks are likely to be implicated. Furthermore, ToM deficits in MCI are associated with a decline in everyday skills such as writing or paying bills.
We aimed to compare the rates of burden amongst caregivers of participants with mild cognitive impairment (MCI), compared to a control group. We also aimed to identify factors in both the caregiver and patient that are associated with significant levels of burden.This was a cross-sectional study. Sixty-four participants with MCI, 36 control-participants and their respective caregivers/informants were recruited to a university research clinic. The proportion of those who showed clinically significant levels of burden was determined by a Zarit Burden Interview score of >21. The associations of burden in MCI-caregivers were calculated in the following categories; participant characteristics (including depressive symptoms, cognition and informant ratings of cognitive and behavioural change); caregiver characteristics; and the caregiving context. Multivariate analyses were performed to examine the relative contribution of individual variables to burden amongst MCI-caregivers.We found that 36% of MCI-caregivers reported clinically significant levels of burden, twice that of the control informant group. Participant behavioural problems contribute most to burden, with participant depression and possibly cognition also having a significant association.Caregiver burden is a considerable problem in MCI and shares some of the same characteristics as caregiver burden in dementia, namely a strong association with challenging behaviours in the patient. This has implications for further research and intervention studies.
Background: Impaired emotion recognition in dementia is associated with increased patient agitation, behavior management difficulties, and caregiver burden. Emerging evidence supports the presence of very early emotion recognition difficulties in mild cognitive impairment (MCI); however, the relationship between these impairments and psychosocial measures is not yet explored. Methods: Emotion recognition abilities of 27 patients with nonamnestic MCI (naMCI), 29 patients with amnestic MCI (aMCI), and 22 control participants were assessed. Self-report measures assessed patient functional disability, while informants rated the degree of burden they experienced. Results: Difficulties in recognizing anger was evident in the amnestic subtype. Although both the patient groups reported greater social functioning disability, compared with the controls, a relationship between social dysfunction and anger recognition was evident only for patients with naMCI. A significant association was found between burden and anger recognition in patients with aMCI. Conclusions: Impaired emotion recognition abilities impact MCI subtypes differentially. Interventions targeted at patients with MCI, and caregivers are warranted.
Background: Research suggests that deficits in emotion recognition are evident in individuals with amnestic mild cognitive impairment (aMCI), a group ‘at risk’ of developing dementia. The mechanisms underlying this deficit, however, are unclear. Objective: In this study, we sought to determine whether there are alterations in the way in which individuals with MCI visually explore emotional facial stimuli. Methods: Eighteen healthy older controls (mean age = 64.6 years) and 32 individuals with MCI were recruited including 18 with the non-amnestic multiple domain (naMCI-md) subtype (mean age = 63.8 years) and 14 with the amnestic multiple domain (aMCI-md) subtype (mean age = 67.9 years). All participants were given a novel eye-tracking paradigm to investigate eye gaze while viewing images of emotional faces on a computer screen. Results: Analyses of eye gaze revealed no significant difference in the percentage of time that groups spent fixating on facial and peripheral facial regions when viewing emotional faces. All participants showed a relative preference for the eye region of faces relative to all other regions. Individuals with aMCI-md were found to be less accurate than controls and naMCI-md on emotion recognition measures. For naMCI-md individuals, significant relationships were found between efficiencies in visual scanning and increased fixation time on the eye region. Conclusions: Visual processing strategies adopted by aMCI-md individuals when exploring emotional faces do not significantly differ from those of healthy controls or naMCI-md individuals. This suggests that impaired facial emotion recognition in aMCI-md is not likely accounted for by visual processing differences, but rather may reflect an eroded ability to extract meaningful cues from the eye region.
Background: Person-centered care is considered beneficial for persons with dementia. Objective: To evaluate the impact of a person-centered knowledge translation intervention on the quality of healthcare and outcomes for persons with dementia. Methods: Over nine months, sub-acute hospital nursing, allied health, and medical staff (n = 90) participated in online and/or face-to-face person-centered education and were supported by senior nursing, allied health, and medical staff champions (n = 8) to implement person-centered healthcare. The quality of healthcare service, ward climate and care delivery were evaluated pre/post study intervention. In the week following hospital admission (Time 1) and week of discharge (Time 3), agitation incidence (co-primary outcome) was assessed in participants with dementia (n = 80). Participant delirium (co-primary outcome), accidents/injuries, psychotropic medicines, length of stay, readmission and discharge destination (secondary outcomes) were compared with a retrospective group (n = 77) matched on demographics, cognition and function in activities of daily living. Results: Improvements occurred post-intervention in service quality by 17.5% (p = 0.369, phi = 0.08), ward climate by 18.1% (p = 0.291, phi = 0.08), and care quality by 50% (p = 0.000, phi = 0.37). Participant agitation did not change from Time 1 to Time 3 (p = 0.223). Relative to the retrospective group, significant reductions occurred in participant delirium (p = 0.000, phi = 0.73), incidents/injuries (p = 0.000, phi = 0.99), psychotropic medicine use (p = 0.030, phi = 0.09), and hospital readmissions within 30 days (p = 0.002, phi = 0.25), but not in discharge to home (p = 0.171). Conclusions: When person-centered healthcare knowledge is translated through staff education and practice support, persons with dementia can experience improved healthcare services and clinical outcomes, while healthcare services can benefit through reductions in unplanned service use.
