'Because my brain isn't as active as it should be, my eyes don't always see': a qualitative exploration of the stress process for those living with posterior cortical atrophy

The Graded Incomplete Letters Test (GILT): a rapid test to detect cortical visual loss, with UK Biobank implementation

Impairments of object recognition are core features of neurodegenerative syndromes, in particular posterior cortical atrophy (PCA; the 'visual-variant Alzheimer's disease'). These impairments arise from damage to higher-level cortical visual regions and are often missed or misattributed to common ophthalmological conditions. Consequently, diagnosis can be delayed for years with considerable implications for patients. We report a new test for the rapid measurement of cortical visual loss - the Graded Incomplete Letters Test (GILT). The GILT is an optimised psychophysical variation of a test used to diagnose cortical visual impairment, which measures thresholds for recognising letters under levels of increasing visual degradation (decreasing "completeness") in a similar fashion to ophthalmic tests. The GILT was administered to UK Biobank participants (total n=2,359) and participants with neurodegenerative conditions characterised by initial cortical visual (PCA, n=18) or memory loss (typical Alzheimer's disease, n=9). UK Biobank participants, including both typical adults and those with ophthalmological conditions, were able to recognise letters under low levels of completeness. In contrast, participants with PCA consistently made errors with only modest decreases in completeness. GILT sensitivity to PCA was 83.3% for participants reaching the 80% accuracy cut-off, increasing to 88.9% using alternative cut-offs (60% or 100% accuracy). Specificity values were consistently over 94% when compared to UK Biobank participants without or with documented visual conditions, regardless of accuracy cut-off. These first-release UK Biobank and clinical verification data suggest the GILT has utility in both rapidly detecting visual perceptual losses following posterior cortical damage and differentiating perceptual losses from common eye-related conditions.

Development of a Best Practice Guidance on Online Peer Support for People with Young-Onset Dementia

This work aimed to develop a Best Practice Guidance on online peer support for people with young-onset dementia (YOD). The Best Practice Guidance was developed through a systematic literature review, focus groups, an online survey, and interviews and consultations with people with YOD and professionals. The Best Practice Guidance consists of two parts. Part 1 contains information for people with YOD about what online peer support entails, what to expect from it, and how to get involved. Part 2 is aimed at those who facilitate or moderate online peer support (professionals or people with lived experience) and includes guidelines on how to optimize online peer support for people with YOD. The Best Practice Guidance on online peer support provides (1) people with YOD with evidence-based, relevant, and accessible information about what online peer support entails and how it could help them, (2) providers and facilitators with guidelines on how to optimize online peer support for people with YOD, and (3) healthcare professionals with a concise and accessible tool for signposting. Future research is needed to implement and disseminate the Best Practice Guidance among dementia organizations and healthcare practices and should include rigorous studies on the implementation and sustainability of online peer support for people with YOD.

Exploring experiential differences in everyday activities - A focused ethnographic study in the homes of people living with memory-led Alzheimer's disease and posterior cortical atrophy

BACKGROUND

Supporting ageing in place, quality of life and activity engagement are public health priorities for people living with dementia, but little is known about the needs and experiences of community-dwelling people with rarer forms of dementia with lesser known symptoms. Posterior cortical atrophy (PCA) is a rare form of dementia usually caused by Alzheimer's disease but which is characterised by diminished visual processing (rather than a dominant memory problem), which poses challenges for maintaining independence and accessing appropriate support.

METHODS

This study used a comparative qualitative design and focussed ethnographic methods to explore experiential differences in activity engagement for 10 people with the most common, memory-led presentation of Alzheimer's disease and 10 people with posterior cortical atrophy within their everyday home environments.

RESULTS

While the data collection revealed much rich variation in individual and contextual factors, some tentative high-level differences in the experiences of everyday activities could be drawn out, seemingly attributable to the different diagnoses' differing dominant symptoms. These included people with posterior cortical atrophy being less likely to use environmental cues to initiate activities, and more likely to withhold from asking for support because of preserved insight into the impact of this on carers. This lack of initiation of activities could be misinterpreted as apathy. People with posterior cortical atrophy also were discouraged from engaging in activities by disorientation within the home, and difficulties localising, identifying and manipulating objects. People with the more common, memory-led presentation of Alzheimer's disease exhibited more memory-based difficulties with engaging with activities such as forgetting planned activities, where to locate the items required for an activity and the steps involved. Despite these distinct symptom-led challenges, all participants and their family members demonstrated resourcefulness and resilience in making creative adaptations to support continued engagement in everyday activities, supporting the widely reported management strategies of people with dementia of the Alzheimer's type more generally.

CONCLUSIONS

These findings offer helpful insights into some the differing impacts dementia related visual and memory impairments can have on everyday activity engagement, which will be helpful for others navigating these challenges and the health and social care practitioners working with people affected by these conditions. The findings also highlight the vast individual variation in the multitude of individual and contextual factors involved in everyday activity engagement, and suggest important areas for future work utilising methods which are similarly high in ecological validity and accessibility as the home-based focussed ethnographic methods utilised here.

Peer Support for Caregivers of People Living with Posterior Cortical Atrophy in Melbourne, Australia: A Feasibility Study

Posterior Cortical Atrophy (PCA) is a rare form of young-onset dementia that causes early visuospatial and visuoperceptual deficits. The symptom profile of Posterior Cortical Atrophy leads to very specific care needs for those affected, who often rely on informal caregivers (including friends and family). Rare dementia support groups can be useful for both patients and their caregivers to assist with knowledge sharing, psychoeducation, and the provision of psychosocial support. Despite this, few such support groups exist. The purpose of this study was to examine a PCA support group for caregivers of individuals living with PCA. We held a structured psychoeducation support group comprised of four sessions with the aim being to provide education, strategies for the management of the disease, and peer support. Caregivers' mental health and quality of life were assessed. The results of our study showed that support group participation was a positive experience and assisted with increasing the knowledge of caregivers and fostering social connections. We suggest that peer support groups may be beneficial for both people living with PCA and their caregivers. We recommend that future quantitative and qualitative research is conducted to further assess health-promotion benefits to people living with PCA and their caregivers, and to assess their development and implementation in different contexts.

"I Want to Do Something" - Exploring What Makes Activities Meaningful for Community-Dwelling People Living With Dementia: A Focused Ethnographic Study

Supporting ageing in place, quality of life, and activity engagement are public health priorities for people with dementia. The importance of maintaining opportunities for meaningful activities has been widely acknowledged for those with dementia in long-term care, but little is known about what makes activities meaningful for, and how they are experienced by, people with different types of dementia in their own homes. This study used focussed ethnographic methods to explore the motivations and meanings of everyday activity engagement within the homes of 10 people with memory-led Alzheimer's disease and 10 people with posterior cortical atrophy. While participants' interactions with their everyday environments were challenged by their diagnoses, they were all finding ways to continue meaning-making via various activities. The main findings are encapsulated in three themes: (1) The fun and the function of activities; (2) Reciprocities of care, and (3) The constitution and continuity of (a changing) self. Ongoing engagement with both fun and functional activities offered participants living with different dementias opportunities to connect with others, to offer care and support (as well as receive it), and to maintain a sense of self and identity. Implications are discussed regarding the development and delivery of tailored interventions and support to enable continued engagement in meaningful activities for people with different types of dementia living in the community.

Social cognition and behavioral changes in patients with posterior cortical atrophy

Posterior cortical atrophy (PCA) is a rare neurodegenerative condition characterized by progressive visual and visuospatial dysfunction. The consensus criteria state that patients should present "relatively spared behavior and personality" in early stages. However, limited research has focused on these symptoms in PCA. This study compared 157 patients with PCA in early stages of the disease with 352 healthy controls (HC), 202 typical AD (tAD), and 177 logopenic variant primary progressive aphasia (lvPPA) patients from the National Alzheimer's Coordinating Center (NACC) dataset. They were compared using clinician ratings of behavioral symptoms, informant- and clinician-filled questionnaires and patient-facing tests of behavior and social cognition. Results showed that PCA individuals exhibited many behavioral symptoms, the more frequently reported being anxiety, depression, apathy, and irritability. During cognitive testing, clinicians observed disorganized and reactive behaviors, but no insensitive behaviors. Informant reports indicated that PCA patients exhibited higher levels of inhibition and anxiety in response to stimuli associated with non-reward, novelty, and punishment. Social norms knowledge and empathy were overall preserved, although slight decreases in perspective-taking and socioemotional sensitivity were observed on informant-rated questionnaires. Except for more elevated neuropsychiatric symptoms in tAD, the three AD variants had similar profiles. Our findings provide insights into the social cognition and behavioral profiles of PCA, highlighting patterns of preservations and mild impairments, even in the early stages of the disease. These results contribute to a more complete understanding of non-visual symptoms in PCA and have implications for diagnostic and intervention strategies.

Person-Environment Exchange Processes in Transition into Dementia: A Scoping Review

BACKGROUND AND OBJECTIVES

The important role that the environment plays in the lives of older people is widely acknowledged. To date, little is known about person-environment processes during the early stages of dementia. This scoping review aims to provide an overview of the processes involved during early dementia and the relationship to different dimensions of their life space.

RESEARCH DESIGN AND METHODS

A scoping review was conducted according to the Johanna Briggs Institute Manual, which involved searching for research on early dementia and the environment across 3 databases.

RESULTS

A total of 1,358 records were screened, with 284 sources included in the first categorization of the diverse relationships that exist between the environment and the person living with early dementia. Finally, 102 sources were selected that describe person-environment exchange processes of agency, belonging, or stress. People living with dementia actively shape, use, seek out, and avoid their environment as a reaction to both declining abilities and environmental barriers. Specifically, feelings of connectedness and familiarity are important.

DISCUSSION AND IMPLICATIONS

Taking both an environmental gerontology perspective and a processual, that is, transition perspective broadens the understanding of the experience and behavior of people living with early dementia. They constantly interact with and shape their environment and desire a sense of belonging. This sense of belonging might be threatened by dementia but can be actively reinforced by people living with dementia. These person-environment processes and their dynamics over time should be further investigated. Especially, quantitative data and data on socioeconomic environments are lacking.

Situating support for people living with rarer forms of dementia

BACKGROUND

Awareness of a multitude of diseases that can cause neurodegenerative decline and their unique symptom profiles in the dementia care and support sectors remains limited. Obtaining an accurate diagnosis and post-diagnostic care and support is a challenge for many people and their families. As part of a larger study examining multi-component forms of support for people living with rarer dementias, the aim of this present study was to examine how rare dementia was situated within the complex social groupings, their organization and embedded discursive constructions that broadly form dementia care and support delivery.

METHODS

Adopting a situational analysis approach, we undertook an examination of public documents and organizational websites within the support sector for people living with dementia in Canada, England, and Wales. We also surveyed professionals to further explore the situation at the point of care and support delivery. Consistent with our approach, data collection and analysis occurred concurrently including the development of a series of analytic maps.

RESULTS

Recognizing the complexities within the situation, our findings provided new insights on the situated structures for support action and the discursive representations that illuminate both the limitations of the current support landscape and possibilities for a more flexible and tailored rare dementia support. Alongside, the predominant universal versus tailored support positionings within our data reinforced the complexity from which a promising new social space for people living with rarer dementias is being cultivated.

CONCLUSIONS

The social worlds engaged in supportive action with people living with rare dementia are less visible within the shadow of a universally constructed dementia support milieu and appear to be negotiated within this powerful arena. However, their evolving organization and discursive constructions point to an emerging new social space for people living with rarer conditions.

'The oxygen of shared experience': exploring social support processes within peer support groups for carers of people with non-memory-led and inherited dementias

OBJECTIVES

To explore support processes and behaviours taking place during online peer support groups for family carers of people living with rare, non-memory-led and inherited dementias (PLWRD).

METHODS

Twenty-five family carers of PLWRD participated in a series of ongoing online peer support groups on the theme of 'Independence and Identity'. Transcripts from 16 sessions were analysed using qualitative directed content analysis with a coding framework informed by Cutrona & Suhr's (2004) Social Support Behaviour Code (SSBC).

RESULTS

Most of the social support behaviours outlined in the SSBC were identified within the sessions, along with two novel social support categories - 'Experiential Support' and 'Community Support' - and novel support behaviours including 'Advocacy and Collective Action' and 'Uses Humour'. The SSBC code 'Relationship' appeared to be of central importance.

CONCLUSIONS

This study sheds light on the unique challenges of the caring context for those affected by non-memory-led and inherited dementias and the significant contributions carers can offer to, and receive from, peers in similar situations. It highlights the importance of services which recognise the value of the informational and emotional expertise of carers of PLWRD and encourages the continued development and delivery of tailored support for these populations.

Video Conferencing Peer Support and Rarer Forms of Dementia: An Exploration of Family Carers' Positive Experiences

Little is known regarding the nuanced experiences of family carers for people living with rare dementias (PLWRD), with no known literature exploring their positive experiences of caring discussed within peer support group settings. This article explores family carers of PLWRD's positive experiences reported in video conferencing peer support groups. Six peer support group sessions involving a total of nine participants were qualitatively analysed using thematic analysis, guided by the conceptual framework of positive aspects of caring (CFPAC) (Carbonneau et al., 2010). Six themes were identified: (1) Protecting, maintaining, enjoying and finding strength in their relationship with the PLWRD; (2) Using tools and resources in response to challenges; (3) Positive impact of interactions and others' responses to the dementia; (4) Overcoming barriers to taking a break while maintaining their wellbeing, (5) Maintaining positive outlooks and showing psychological resilience in adversity; and (6) Attributing meaning to the caring role. This article highlights family carers of PLWRD's positive psychological, physical and social resources, balanced against the challenges of caring and maintaining their wellbeing, and identifies ways of promoting family carers' positive caring experiences and resources within healthcare and supportive settings.

"I felt like I had been put on the shelf and forgotten about" - lasting lessons about the impact of COVID-19 on people affected by rarer dementias

BACKGROUND

The public health measures imposed in many countries to contain the spread of COVID-19 resulted in significant suspensions in the provision of support and care for people with dementia. The negative effects of these measures have been extensively reported. However, little is known about the specific impact on people with young onset, non-memory-led and inherited dementias. This group may have experienced different challenges compared to those with late onset dementia given their non-memory phenotypes and younger age. We explored the impact of the first COVID-19 lockdown on people living with familial Alzheimer's disease, behavioural variant frontotemporal dementia, familial frontotemporal dementia, dementia with Lewy bodies, posterior cortical atrophy and primary progressive aphasia and their carers in the UK and their self-reported strategies for coping.

METHODS

This was a mixed methods study. An online survey was administered to people with dementia and family carers recruited via Rare Dementia Support. Free-text responses were analysed using framework analysis to identify key issues and themes.

RESULTS

184 carers and 24 people with dementia completed the survey. Overall, people with dementia experienced worsening of cognitive symptoms (70%), ability to do things (62%), well-being (57%) and changes to medication (26%) during lockdown. Carers reported a reduction in the support they received (55%) which impacted their own mental health negatively. Qualitative analysis of free-text responses shed light on how the disruption to routines, changes to roles and responsibilities, and widespread disconnection from friends, family and health and social care support varied according to phenotype. These impacts were exacerbated by a more general sense that precious time was being lost, given the progressive nature of dementia. Despite significant challenges, respondents demonstrated resilience and resourcefulness in reporting unexpected positives and strategies for adapting to confinement.

CONCLUSIONS

This study has highlighted the specific impacts of the COVID-19 restrictions on people with young onset, non-memory-led and inherited dementias, including behavioural variant frontotemporal dementia, primary progressive aphasia and posterior cortical atrophy, and their carers. The specific challenges faced according to diagnosis and the self-reported strategies speak to the importance of - and may inform the development of - tailored support for these underrepresented groups more generally.

Diagnosis and Management of Posterior Cortical Atrophy

Purpose of review

The study aims to provide a summary of recent developments for diagnosing and managing posterior cortical atrophy (PCA). We present current efforts to improve PCA characterisation and recommendations regarding use of clinical, neuropsychological and biomarker methods in PCA diagnosis and management and highlight current knowledge gaps.

Recent findings

Recent multi-centre consensus recommendations provide PCA criteria with implications for different management strategies (e.g. targeting clinical features and/or disease). Studies emphasise the preponderance of primary or co-existing Alzheimer's disease (AD) pathology underpinning PCA. Evidence of approaches to manage PCA symptoms is largely derived from small studies.

Summary

PCA diagnosis is frequently delayed, and people are likely to receive misdiagnoses of ocular or psychological conditions. Current treatment of PCA is symptomatic - pharmacological and non-pharmacological - and the use of most treatment options is based on small studies or expert opinion. Recommendations for non-pharmacological approaches include interdisciplinary management tailored to the PCA clinical profile - visual-spatial - rather than memory-led, predominantly young onset - and psychosocial implications. Whilst emerging disease-modifying treatments have not been tested in PCA, an accurate and timely diagnosis of PCA and determining underlying pathology is of increasing importance in the advent of disease-modifying therapies for AD and other albeit rare causes of PCA.

Receiving a diagnosis of young onset dementia: a scoping review of lived experiences

OBJECTIVES

Personal experiences of receiving a diagnosis of young onset dementia (YOD) are often overlooked in a complex assessment process requiring substantial investigation. A thematic synthesis of published until November 2018 qualitative studies was completed to understand the lived experiences of younger people. This informed a Delphi study to learn how diagnostic processes could be improved, identify the strengths and weaknesses of current approaches, and help educate professionals concerning key issues.

METHOD

Systematic searches of bibliographic databases were conducted involving self-reported experiences of diagnosis of YOD. Eight out of 47 papers identified were quality assessed using Walsh & Browne's criteria for methodological appraisal.

RESULTS

The review emphasises that delays in diagnosis can often be attributed to (1) delays in accessing help, and (2) misattribution of symptoms by the clinician. The impact of diagnosis is influenced by the clinician's use of language; and reactions to diagnosis varied from feelings of reassurance (in that their symptoms are now explained), to shock and destabilisation.

CONCLUSION

This review suggests that improving the recognition of presenting symptoms, reducing diagnostic errors, and identifying the emotional needs arising from diagnosis are required to improve the diagnostic experience for younger adults, and to promote future engagement with services.

Good Practice in Needs-based Post-diagnostic Support for People with Young Onset Dementia: Findings from the Angela Project

Evidence on post-diagnostic support for people with young onset dementia is scarce. Previous studies have employed a problem-focused approach; however, evidence on 'what works' in real-life practice is essential to develop recommendations for service design and delivery. This study aimed to provide insight into 'what works' from the perspectives of people with young onset dementia and their supporters. We gathered free-text responses on positive service experiences via a UK cross-sectional survey. Inductive thematic analysis was used to identify the objectives of positive services and the needs these met. Follow-up interviews enabled in-depth insights from people with diverse diagnoses, ages, and social situations. These were analysed using a template drawn from the survey. 233 survey respondents gave 856 examples of positive support. Analysis of 24 follow-up interviews led to 16 themes clustered under three superordinate themes: 'Maintaining autonomy', 'Being myself' and 'Togetherness'. We found that positive services address the disruptions to sense of agency, selfhood and meaningful relationships that are experienced by those with young onset dementia. The study provides an in-depth understanding of the needs met by positive services for younger people with dementia. Our nuanced findings on good practice can inform age-specific guidelines for young onset dementia and indicate how personalisation can work in practice to help people with young onset dementia to maintain identity, autonomy and connections.

Psychosocial Stressors and Adaptive Coping Strategies in Couples After a Diagnosis of Young-Onset Dementia

BACKGROUND AND OBJECTIVES

Diagnoses of young-onset dementias (YODs) are devastating for persons with dementia and spousal caregivers yet limited work has examined both partners' perceptions of challenges and coping after diagnosis. This qualitative study investigated the psychosocial stressors and adaptive coping strategies in couples diagnosed with YOD to inform the development of psychosocial support resources.

RESEARCH DESIGN AND METHODS

We conducted live video dyadic interviews with couples (persons with YOD and spousal caregivers together; N = 23 couples). We transcribed interviews and coded data based on a hybrid deductive-inductive approach, with the structure of the coding framework informed by the stress and coping framework, and all codes derived from the data. We derived themes and subthemes related to psychosocial stressors and adaptive coping.

RESULTS

We identified 5 themes related to psychosocial stressors: the impact of diagnosis, social and family relationships, changing roles and responsibilities, planning for an uncertain future, and couple communication and relationship strain. We identified 7 themes related to adaptive coping strategies: processing emotions and cultivating acceptance, promoting normalcy, efforts to preserve persons with YOD's independence and identity, collaborative and open communication, social support, meaning-making, humor, and positivity, and lifestyle changes and self-care.

DISCUSSION AND IMPLICATIONS

We replicated several themes regarding stressors and adaptive coping strategies from prior YOD research and identified novel themes and subthemes related to dyadic stressors, sources of couples' relationship strain, and the ways in which couples effectively cope with YOD. Findings inform the development of dyadic interventions to reduce YOD-related distress for both persons with dementia and spousal caregivers.

OUP accepted manuscript

BACKGROUND AND OBJECTIVES

Young-onset dementias (YODs) are a set of progressive illnesses that are stressful for both persons with the diagnosis and their care-partners. Although the stressors differ based on their roles and individual experiences, both individuals are at risk for heightened emotional distress (e.g., depression and anxiety). Understanding the unique stressors for each partner and adaptive coping strategies to manage these stressors is important for informing individual and couples-based psychosocial interventions.

RESEARCH DESIGN AND METHODS

We conducted open-ended individual interviews with persons with YOD (N = 12) and their care-partners (i.e., romantic partner; N = 17) over live video. We utilized a hybrid of deductive and inductive analysis techniques to extract individual-level themes and subthemes regarding stressors and adaptive coping strategies.

RESULTS

Persons with YOD identified stressors including burden of YOD symptoms, loss of familial roles, resentment toward partner, isolation, and fear of the future. Care-partners identified stressors including managing their partners' symptoms, increased responsibilities, caregiving role, loss of intimacy, social isolation, and grief. For adaptive coping strategies, persons with YOD endorsed use of acceptance, promotion of independence, social support, and engaging in pleasurable activities. Care-partners endorsed value of learning about the diagnosis, using resources, optimism, social support, and self-care.

DISCUSSION AND IMPLICATIONS

Findings highlight the unique experiences of persons with YOD and their care-partners. Identified themes can be used to inform role-specific psychosocial interventions for both individuals and couples coping with YOD.

A qualitative meta-synthesis of common and unique preferences for supportive services among persons with young onset dementia and their caregivers

BACKGROUND AND OBJECTIVES

Young onset dementias (young onset dementia) produce a myriad of stressors for persons with young onset dementia and their caregivers, yet there is a critical shortage of supportive services that address their needs. To develop such services, it is necessary to first comprehensively understand persons' with young onset dementia and their caregivers' service preferences. Therefore, we conducted a meta-synthesis to integrate and summarize qualitative data on persons' with young onset dementia and caregivers' preferences for supportive services for young onset dementia, defined as support provided by medical providers, psychosocial interventions, and any other resources/services provided to promote positive adjustment in persons with young onset dementia and their caregivers.

RESEARCH DESIGN AND METHODS

We searched five electronic databases for qualitative articles from inception to January 2020. We extracted and synthesized data from eligible articles using thematic analysis. After removal of duplicates, we screened 219 articles identified through database and hand searches.

FINDINGS

Forty-three studies met our inclusion criteria. We extracted findings from these 43 studies on preferences within three a priori defined domains: 1) general characteristics of supportive services, 2) format and modality of supportive services, and 3) content for supportive services. Persons with young onset dementia and caregivers predominantly expressed common preferences, with some unique preferences based on their specific roles within the partnership.

DISCUSSION AND IMPLICATIONS

Persons with young onset dementia and their caregivers endorsed largely overlapping preferences, including having direct contact with providers and the ability to participate together in programs that have content and skills relevant to their specific needs and challenges. Findings can directly inform the format, content, and procedures of supportive services for persons with young onset dementia and their caregivers.

Neuropsychological deficits in Posterior Cortical Atrophy and typical Alzheimer's disease: A meta-analytic review

AIMS

To identify cognitive tests that best differentiate between Posterior Cortical Atrophy (PCA) and typical Alzheimer's Disease (tAD), as well as PCA and healthy control (HC) participants.

METHOD

Medline, PsycInfo and Web of Science were systematically searched using terms related to PCA, tAD, and cognitive testing. Seventeen studies were identified, including 441 PCA, 391 tAD, and 284 HC participants. Standardised effect sizes of mean scores were calculated to measure performance differences on cognitive tests for PCA versus tAD and PCA versus HC groups. Meta-analyses used a random effects model.

RESULTS

The most discriminating cognitive tests for PCA and tAD presentations were measures of visuospatial function and verbal memory. Large, significant effect sizes were produced for all measures of visuospatial function, most notably for Rey-Osterrieth Copy (Hedges' g = -2.79), VOSP Fragmented letters (Hedges' g = -1.73), VOSP Dot Counting (Hedges' g = -1.74), and VOSP Cube Analysis (Hedges' g = -1.98). For measures of verbal memory, the RAVLT delay and Digit Span Backwards produced significant medium effects (Hedges' g = .62 and -.56, respectively).

CONCLUSION

Establishing a common framework for testing individuals with PCA has important implications for diagnosis and treatment, and forms a practical objective for future research. Findings from this meta-analysis suggest that measures of visuospatial function and verbal memory would form an important part of this framework.

Receiving a diagnosis of young onset dementia: Evidence-based statements to inform best practice

Introduction

Better understanding of patient experience is an important driver for service improvements and can act as a lever for system change. In the United Kingdom, the patient experience is now a central issue for the National Health Service Commissioning Board, clinical commissioning groups and the providers they commission from. Traditionally, dementia care in the United Kingdom has focused predominantly on the individual experience of those with late onset dementia, while the voice of those with young onset dementia has been, comparatively, unheard. This study aims to improve the understanding of the personal experience of younger people undergoing investigation for dementia.

Methods

A modified Delphi approach was undertaken with 18 younger people with dementia and 18 supporters of people with young onset dementia. Questions were informed by a scoping review of the literature (O’Malley, M., Carter, J., Stamou, V., Lafontaine, J., & Parkes, J. (2019a). Receiving a diagnosis of young onset dementia: A scoping review of lived experiences. Ageing & Mental Health, 0(0), 1-12). Summary individual statements were refined over two rounds to a final list of 29 key statements.

Results

Twenty-seven of these statements were rated as absolutely essential or very important and included (1) for the general practitioner to identify dementia in younger people, (2) clinicians should be compassionate, empathic and respectful during the assessment and particularly sensitive when providing information about a diagnosis, and (3) remembering that receiving the diagnosis is a lot to absorb for a person with dementia and their supporter. Statistical analyses found no difference in the scoring patterns between younger people with dementia and supporters, suggesting similar shared experiences during the diagnostic process.

Conclusion

Understanding the uniquely personal experience of young people going through the process of diagnosis for dementia is essential to provide person-centred, needs-led, and cost-effective services. Patient’s values and experiences should be used to support and guide clinical decision-making.

In It Together: A Qualitative Meta-Synthesis of Common and Unique Psychosocial Stressors and Adaptive Coping Strategies of Persons With Young-Onset Dementia and Their Caregivers

BACKGROUND AND OBJECTIVES

The common and unique psychosocial stressors and adaptive coping strategies of people with young-onset dementia (PWDs) and their caregivers (CGs) are poorly understood. This meta-synthesis used the stress and coping framework to integrate and organize qualitative data on the common and unique psychosocial stressors and adaptive coping strategies employed by PWDs and CGs after a diagnosis of young-onset dementia (YOD).

RESEARCH DESIGN AND METHODS

Five electronic databases were searched for qualitative articles from inception to January 2020. Qualitative data were extracted from included articles and synthesized across articles using taxonomic analysis.

RESULTS

A total of 486 articles were obtained through the database and hand searches, and 322 articles were screened after the removal of duplicates. Sixty studies met eligibility criteria and are included in this meta-synthesis. Four themes emerged through meta-synthesis: 1) common psychosocial stressors experienced by both PWDs and CGs, 2) unique psychosocial stressors experienced by either PWDs or CGs, 3) common adaptive coping strategies employed by both PWDs and CGs, and 4) unique adaptive coping strategies employed by either PWDs or CGs. Within each meta-synthesis theme, subthemes pertaining to PWDs, CGs, and dyads (i.e., PWD and CG as a unit) emerged.

DISCUSSION AND IMPLICATIONS

The majority of stressors and adaptive coping strategies of PWDs and CGs were common, supporting the use of dyadic frameworks to understand the YOD experience. Findings directly inform the development of resiliency skills interventions to promote adaptive coping in the face of a YOD diagnosis for both PWDs and CGs.

Living with young onset dementia: reflections on recent developments, current discourse, and implications for policy and practice

Recent research on young onset dementia (formal diagnosis at age <65) evidences emerging work around pre-diagnosis, diagnosis and the need to improve post-diagnostic support for this group. An increased awareness of young onset dementia has led to the establishment of peer-support groups, support networks and the involvement of people affected by dementia in research. However, the need to join up services at the systems level persists. Third-sector organisations that offer post-diagnostic support at the community level rely heavily on volunteers. Implications for policy and practice are that community-based commissioning of integrated services between health care, social care and the third sector would go a long way to providing the continuity and stability required in dementia support and care along the illness trajectory. This discussion document was written in collaboration with diagnostic services, the charity sector and conversations with people living with, and affected by, dementia.

Stress and neurodegeneration

Neurodegenerative diseases are a great concern because of aging worldwide population. Despite substantial effort to advance our understanding of the etiology and potential treatment of neurodegeneration, there remains a paucity of information with respect to this complex disease process. Interestingly, stress has been implicated among the potential mechanisms implicated in neurodegenerative pathology. Given the increase in chronic stress in modern society, this premise warrants further investigation. The aim of this review is to evaluate the influence of stress on neurodegeneration, the effect of neurodegenerative diseases diagnosis on stress, and therapeutic strategies for neurodegenerative diseases with a special focus on stress reduction. Neurodegenerative disorders such as Alzheimer's, Parkinson's and Huntington's Disease showed an acceleration in disease progression and a worsening of symptoms under stress. Some therapies (e.g., yoga, meditation) focused on reducing stress showed beneficial effects against neurodegeneration. Nevertheless, more studies are necessary in order to completely understand the implications of stress in neurodegeneration and the usefulness of stress reduction in the treatment thereof.

Health and social care practitioners' understanding of the problems of people with dementia-related visual processing impairment

It has been highlighted that health and social care staff need a greater awareness of the needs and problems of those people with young onset dementia in the UK. Symptoms of Alzheimer's disease are relatively well known (memory loss, disorientation, language difficulties and behavioural problems). However, there is less awareness of dementia-related visual processing impairments in Alzheimer's disease, Dementia with Lewy Bodies or rarer dementia syndromes such as posterior cortical atrophy (PCA), leading to delayed assessment, diagnosis and management. This qualitative study explored health and social care practitioners' opinions of the needs of people with dementia-related visual processing impairment (such as individuals with PCA) and identify any training that these practitioners might need. Social workers, occupational therapists, care home staff, rehabilitation workers (visual impairment), optometrists and admiral nurses participated in focus groups or one-to-one semi-structured interviews. All participants were shown video clips of people with dementia-related visual impairment to facilitate discussion. Sixty-one participants took part in focus groups or interviews between November 2014 and December 2015. Participants' experiences and understanding of dementia were explored and thematic analysis of the data identified two major themes. Theme 1 explores participants' understanding of dementia-related visual impairments. Theme 2 recounts how participants address and support people with dementia-related visual impairment and their families. Participants discussed, reflected and critically analysed the video clips during data collection. Most considered new perspectives of their own clients' difficulties and those participants working with people with rarer dementias consolidated their experiences. However, some participants seemed hesitant to accept the existence of visual processing impairment arising due to dementia, rationalising novel information to existing understanding of memory loss or behavioural problems. This study highlights that health and social care practitioners want more training and better understanding of less well-recognised symptoms of dementia and rarer syndromes (including PCA) to ensure appropriate, evidence-based assessment and intervention.

Contributions of patient and citizen researchers to ‘Am I the right way up?’ study of balance in posterior cortical atrophy and typical Alzheimer’s disease

The current report describes the journey from the sharing of a single, extraordinary experience during a support group conversation to the development of a novel scientific investigation of balance problems in a rarer form of dementia. The story centres around the involvement of people living with or caring for someone with posterior cortical atrophy (often referred to as the visual variant of Alzheimer’s disease) in highlighting hitherto under-appreciated consequences of their condition upon their ability to know ‘Am I the right way up?’. We describe how comments and descriptions of these balance symptoms were collated and communicated, and the involvement of people with posterior cortical atrophy in shaping a series of scientific hypotheses and developing and adapting appropriate experimental materials and procedures. We also reflect more broadly on how we might better recognise, acknowledge and encourage different forms of involvement, and describe several engagement-inspired extensions to the research involving people living with dementia, scientists and artists.
