A profile of identity in early-stage dementia and a comparison with healthy older people

Change in the psychological self in people living with dementia: A scoping review

Alterations in one's sense of self are often considered a significant psychological symptom of dementia. However, the self is not a unified construct; it consists of a set of closely connected, yet substantive, manifestations which might not be equally impacted by dementia. Recognising the multidimensional nature of the self, the current scoping review aimed to explore the nature and scope of the evidence demonstrating change in the psychological self in people living with dementia. Adopting a cognitive psychological framework, a hundred and five (105) quantitative and qualitative studies were reviewed, and findings were organised into three main types of self-manifestations: high-order manifestations, functional aspects of the self, and foundational manifestations. Overall, the results show that although there are alterations in some of these different manifestations of the self, these do not imply a global loss of selfhood. Despite notable cognitive changes during dementia, it seems that preserved aspects of self may be enough to compensate for potential weakening of some self-processes such as autobiographical recall. Better understanding alterations in selfhood is key to addressing psychological symptoms of people living with dementia, such as feelings of disconnection and reduced agency, and may inform new pathways for dementia care interventions.

Art box deliveries: The experiences of people with dementia and their carers during the Covid 19 lockdown

Art workshops have been looked at before in terms of impact for people with dementia but never those conducted remotely during a pandemic lockdown. Two artists, working with local museums, provided Art workshops for people with dementia and their caregivers. Due to the first Covid 19 lockdown in the UK, the artists set up a weekly delivery service of Home Art Boxes to thirty-three people with dementia and their caregivers over a period spanning 11 months. The artists received funding from local organisations and the Community Lottery Fund. Thematic analysis of the feedback from the participants regarding the project and the artists themselves provided the data for this evaluation of the project. Seven main themes were identified: organisation of the project; community and connections; supporting the caregivers; enjoyment and enrichment; well-being and cognitive benefits of the projects; equipment and instructions; and drawbacks within the project. The participants' feedback enabled the artists to improve the contents and instructions given each week so that they were able to adjust the activities for those people with dementia whose condition was declining. Implications are that remote Art workshops are possible during lockdown restrictions, but that personal communication is equally important.

Phenomenology of anxiety in people living with mild to moderate dementia: A conceptual meta-ethnographic review

OBJECTIVES

This conceptual review aims to integrate findings from published qualitative studies focusing on individual experiences of people living with dementia to generate a better understanding and conceptualisation of anxiety in dementia, including its subclinical manifestations. The review aims to inform the clinical practice to facilitate the development of targeted psychological interventions and provision of holistic support to people living with dementia.

DESIGN

The review was conducted according to the guide for reporting meta-ethnographic qualitative syntheses eMERGe and the PRISMA guidelines.

RESULTS

The search yielded a total of 2947 studies, out of which 13 were included in the final qualitative synthesis. The interpretive synthesis identified common experiences of people living with mild to moderate dementia, characterised by clusters of themes around worry, emotional experiences, and behavioural reactions in response to the diagnosis of dementia and its symptoms. These represent the components of a conceptual framework of anxiety in mild to moderate dementia, where anxiety is triggered by negative appraisals of living with an irreversible neurodegenerative disease. Stemming from these appraisals of dementia progression and its impact on the person's overall future, the content of worrisome thoughts and concerns include the loss of self and identity, losing independence and the ability to perform previous activities, concerns about being a burden to loved ones, and worry about the impact on interpersonal relationships.

CONCLUSION

This conceptualisation of anxiety in dementia, including its subclinical manifestations facilitates the development of psychological interventions and provision of holistic support to people living with dementia.

Smell your self: Olfactory stimulation improves self-concept in Alzheimer's disease

Research has demonstrated a link between decline in autobiographical memory and decline in the sense of self in Alzheimer's disease (AD). Recent work has also shown that odour is a powerful cue to alleviate decline in autobiographical memory in AD. Based on these findings, we investigated whether odour exposure improves access to self-concept in AD patients. To this end, we invited AD and control participants to make self-related statements (i.e., statements in response to the question "Who am I?") after odour exposure or without odour exposure. We measured the number and the categories of self-related statements (i.e., whether these statements described the psychological, social or physical self) that were generated in each condition. Results demonstrated that both AD and control participants generated more self-statements in the odour condition than in the odor-free condition, especially psychological self-statements. This study is the first to demonstrate the positive influence of olfactory stimulation on the retrieval of self-related knowledge in AD.

Measuring the well-being of people with dementia: a conceptual scoping review

BACKGROUND

Enabling people with dementia to 'live well' is a policy and research priority in many countries. However, instruments for measuring outcomes of psychosocial interventions designed to promote well-being in dementia are often derived from a symptom-focused, loss/deficit approach, or from broad quality of life concepts. A pan-European dementia working group called for research on the development of an alternative asset/strengths-based conceptual framework of well-being in dementia. This paper takes forward this recommendation by developing such a framework and using this to map relevant self-report outcome measures.

METHODS

Three scoping reviews of published studies were conducted iteratively. First, we examined the literature on lived experiences of well-being and quality of life in people with dementia and then the wider dementia literature for application of well-being constructs. The synthesised findings generated conceptual domains of well-being in people with dementia. Corresponding self-report instruments used in dementia research were scoped, categorised within the conceptual framework and their potential value in measuring outcomes for people with dementia was examined.

FINDINGS

Six conceptual domains for the measurement of well-being and 35 self-report instruments that have been used with people with dementia were identified. Six instruments were developed specifically for people with dementia, five were derived from the gerontological literature and 24 from the well-being literature. Fifteen instruments and one sub-scale have been examined for psychometric properties amongst people with dementia. To date, 20 have been used as outcome measures, with seven measuring change over time. A number of identified instruments utilise traditional retrospective Likert-scaling response formats, limiting their potential for use with some groups of people with dementia.

CONCLUSION

An assets/strengths-based framework is presented, outlining structural domains for selecting self-report measures of well-being in people with dementia. It provides a foundation for enhancing research into processes and outcomes of psychosocial interventions, including instrument development, more precise matching of intervention aims with outcome measurement, and newer technology-based 'in-the-moment' measurement.

Discontinuity in the Subjective Experience of Self Among People with Mild-To-Moderate Dementia Is Associated with Poorer Psychological Health: Findings from the IDEAL Cohort

BACKGROUND

The onset and progression of dementia can result in changes in the subjective experience of self, impacting on psychological health.

OBJECTIVE

We aimed to explore the extent to which people with mild-to-moderate dementia experience discontinuity in the subjective experience of self, and the factors associated with this experience for people with dementia and their family caregivers.

METHODS

We used data from the baseline assessment of the IDEAL cohort. Discontinuity in the subjective experience of self was assessed by asking participants about their agreement with the statement 'I feel I am the same person that I have always been'. Participants were divided into those who did and did not experience discontinuity, and the two groups were compared in terms of demographic and disease-related characteristics, psychological well-being, measures of 'living well', and caregiver stress.

RESULTS

Responses to the continuity question were available for 1,465 participants with dementia, of whom 312 (21%) reported experiencing discontinuity. The discontinuity group experienced significantly poorer psychological well-being and had significantly lower scores on measures of 'living well'. There was no clear association with demographic or disease-related characteristics, but some indication of increased caregiver stress.

CONCLUSION

A significant proportion of people with mild-to-moderate dementia describe experiencing discontinuity in the subjective sense of self, and this is associated with poorer psychological health and reduced ability to 'live well' with the condition. Sensitively asking individuals with dementia about the subjective experience of self may offer a simple means of identifying individuals who are at increased risk of poor well-being.

Using memories to support the self in Alzheimer's disease

The impact of memory loss on the self in Alzheimer's disease (AD) is poorly understood. Previous research is mixed on whether episodic or semantic memories are most important for supporting identity. The present study examined autobiographical memories cued by self-images (e.g., I am a father) and non-self-related cues in 16 AD patients and 29 healthy older adults. The AD group generated fewer self-images and memories compared to controls, but demonstrated similar temporal organization of self-cued memories. In both groups, self-images were supported by semantic memories that were temporally clustered around times of identity-formation. These self-supporting memories are proposed to form a scaffold to support the self and may persist the longest in AD, as opposed to memories from early adulthood per se. In both AD and control groups, self-images cued more semantic memories than non-self-relevant cues, further suggesting that semantic autobiographical memories play a fundamental role in supporting the self. These findings demonstrate that the self remains largely intact in AD, in spite of severe episodic memory deficits and global cognitive decline. In later stages of the disease, these self-supporting memories could provide effective tools for reminiscence therapy.

The development of positive psychology outcome measures and their uses in dementia research: A systematic review

Positive psychology is gaining credence within dementia research but currently there is a lack of outcome measures within this area developed specifically for people with dementia. Authors have begun adopting positive psychology measures developed with other populations but there is no consensus around which are more appropriate or psychometrically robust. A systematic search identified measures used between 1998 and 2017 and an appraisal of the development procedure was undertaken using standardised criteria enabling the awarding of scores based on reporting of psychometric information. Twelve measures within the constructs of identity, hope, religiosity/spirituality, life valuation, self-efficacy, community and wellbeing were identified as being used within 17 dementia studies. Development procedures were variable and scores on development criterion reflected this variability. Of the measures included, the Herth Hope Index, Systems of Belief Inventory and Psychological Wellbeing Scale appeared to be the most robustly developed and appropriate for people with dementia.

What contributes to a good quality of life in early dementia? Awareness and the QoL-AD: a cross-sectional study

Background

Self-report quality of life (QoL) measures for people with dementia are widely used as outcome measures in trials of dementia care interventions. Depressed mood, relationship quality and neuropsychiatric symptoms predict scores on these measures, whereas cognitive impairment and functional abilities typically do not. This study examines whether these self-reports are influenced by personality and by the person’s awareness of his/her impairments. A strong negative association between QoL and awareness of deficits would have implications for the validity of self-report in this context and for therapeutic interventions aiming to increase adjustment and coping.

Methods

Participants were 101 individuals with early‒stage dementia and their family carers participating in the Memory Impairment and Dementia Awareness (MIDAS) Study. QoL was assessed using the QoL-AD scale, and awareness was assessed in relation to memory, activities of daily living and social functioning. Self-concept, conscientiousness, quality of relationship and mood were assessed and a brief neuropsychological battery administered. Carers rated their own stress and well-being and reported on neuropsychiatric symptoms. A series of regression analyses predicting QoL-AD were carried out, identifying key variables in each domain of assessment to take forward to an overall model.

Results

Cognitive impairment was not related to QoL. The final model accounted for 57% of the variance in QoL-AD scores, with significant contributions from depressed mood, severity of irritability shown by the person with dementia, self-concept, quality of relationship (rated by the person with dementia) and male gender. The bivariate relationships of QoL-AD with awareness of memory function, awareness of functional abilities and conscientiousness were mediated by both depressed mood and self-concept.

Conclusions

This study reports the most comprehensive approach to evaluation of awareness to date. Most of the indices of awareness used are not related to self-reported QoL. Discrepancies in evaluative judgements of memory function and functional abilities between people with dementia and carers are related to QoL, but this relationship is mediated by both depressed mood and self-concept, which have a much stronger relationship with QoL. The validity of self-report measures of QoL in people with early stage dementia is supported by these results.
