A call to action for the improved identification, diagnosis, treatment and care of people with young onset dementia

Post-diagnostic support for persons with young-onset dementia - a retrospective analysis based on data from the Swedish dementia registry SveDem

BACKGROUND

Approximately 3.9 million persons worldwide have young-onset dementia. Symptoms related to young-onset dementia present distinct challenges related to finances, employment, and family. To provide tailored support, it is important to gain knowledge about the formal support available for persons with young-onset dementia. Therefore, this paper aims to describe formal support for persons with young-onset dementia in Sweden and the factors influencing this support.

METHODS

This retrospective study used data on persons under 65 years of age (n = 284) from The Swedish Registry for Cognitive/Dementia Disorders (SveDem) between 2021 and 2022. SveDem was established to monitor the quality of dementia care in Sweden. Characteristics of participants were obtained, including age, sex, dementia diagnosis, MMSE, medications, accommodation, and care setting. Descriptive statistics and logistic regression were used to test for associations between participant characteristics and post-diagnostic support.

RESULTS

Information and educational support were usually offered to the person with young-onset dementia (90.1%) and their family (78.9%). Approximately half of the sample were offered contact with a dementia nurse (49.3%), counsellor (51.4%), or needs assessor (47.9%). A minority (28.5%) were offered cognitive aids. Six regression models were conducted based on participant characteristics to predict the likelihood that persons were offered support. Support was not predicted by age, sex, children at home, accommodation, or medications. Lower MMSE scores (p < .05) and home help (p < .05) were significantly associated with offer of a needs assessor. Living together was a significant predictor (p < .01) for information and educational support offered to the family. Care setting significantly predicted (p < .01) an offer of information and educational support for the person and family members, as well as contact with a counsellor.

CONCLUSION

This study indicates potential formal support shortages for persons with young-onset dementia in some areas of dementia care. Despite equal support across most characteristics, disparities based on care setting highlight the importance of specialised dementia care. Pre-diagnostic support is minimal, indicating challenges for persons with young-onset dementia to access these services before diagnosis. While our study has identified areas in need of improvement, we recommend further research to understand the changing support needs of those with young-onset dementia.

The experiences and perspectives of older adult mental health professional staff teams when supporting people with young-onset dementia

Background. The diagnosis of young-onset dementia presents significant challenges both for the person and their families, which often differ from the challenges faced with late-onset dementia. Evidence of the experience of service users and carers tends to reveal a negative appraisal of the care received, citing longer diagnosis times, poor clinician knowledge and lack of age-appropriate care. However, evidence looking into staff experiences of supporting someone with young-onset dementia is relatively scarce. The aim of this study was to explore the experiences and reflections of health and social care staff who support people with young-onset dementia within older adult mental health services, and whether their knowledge of the systems they work in could reveal the existence of barriers or facilitators to young-onset dementia care. Methods. Health and social care professionals working with people and carers with young-onset dementia across England were remotely interviewed between September and December 2021. Data were analysed using inductive thematic analysis. Findings. Sixteen staff members were interviewed. Three themes were constructed with six sub-themes. The first theme related to the perception of greater complexity around young-onset dementia support. The second theme describes staff fears around their ability to effectively support people with young-onset dementia, including the perception that young-onset dementia requires specialist input. The final theme describes systemic and structural inefficiencies which provide additional challenges for staff. Conclusions. Providing effective support for people with young-onset dementia and their families requires adjustments both within the clinician role and mental health services. Staff considered young-onset dementia support to be a specialist intervention and felt the services they work for are suited to generic mental health and dementia provision. Findings are discussed with recommendations relating to developing a standardised model of dementia care for young-onset dementia which recognises and responds to the unique experiences of young-onset dementia.

An analysis of the contents of the young-onset dementia helpline: profiles of clients who consulted the helpline themselves

BACKGROUND

Young-onset dementia (YOD) community care requires personalised approaches. Yet, the specific details of YOD consultations are unclear. This study explored how initial consultations correlate with client profiles.

METHODS

Data from regional YOD helplines were used to analyze the main characteristics of people living with YOD or who had concerns about the possibility of YOD (n = 132). Among several categorical variables, the following were used for analysis: age group, sex, type of living arrangement, employment status, presence of dementia, and content of the consultation. To identify groups of items that frequently occur together, strongly connected rules were identified using association rule analysis with the a priori algorithm. To focus on the characteristics of clients, rules related to client characteristics were extracted based on the type of consultation.

RESULTS

A total of 51 rules were identified for the consultations. These rules fell into two categories: (1) consultations for medical matters, which mainly involved employed individuals with undiagnosed dementia, and (2) other consultations on daily life or work, which mainly involved individuals diagnosed with dementia and were characterised by the influence of sex. These rules indicate the importance of medical involvement in confirming the diagnosis and specific individualised care following diagnosis for people living with YOD.

CONCLUSION

Clients with or without a dementia diagnosis were consulted differently in the YOD helplines. Before receiving a diagnosis, medical matters were the main theme of consultations, whereas after receiving a diagnosis, adjustments to daily life or work were the main themes. The results of this study suggest that the needs of people living with YOD and the services they require may vary depending on their backgrounds.

Navigating the Journey of Living with Young-Onset Dementia: Experiences of Spousal Caregivers

Background

Young-onset dementia (YOD) refers to dementia occurring before the age of 65, with Alzheimer's disease being the most common form, posing distinct challenges for spousal caregivers.

Objective

This study aims to investigate the unique experiences of spousal caregivers of persons with YOD in China, where dementia-specific community care services and primary healthcare professionals are relatively lacking, in order to inform the tailored support services development.

Methods

This qualitative-design study utilized semi-structured interviews with 11 spousal caregivers of persons with YOD dwelling in the community. Traditional content analysis was employed to analyze the interview data.

Results

Limited dementia-specific healthcare professionals and low public awareness made diagnosing and accepting YOD a prolonged and challenging journey. Spousal caregivers faced skepticism when seeking diagnosis, exacerbating their burden and emotional stress. Disparities in healthcare professionals and insufficient collaboration between institutions worsened the situation. YOD significantly impacted family dynamics and led to changes in emotional communication within the family. The stigma surrounding YOD raised concerns among spousal caregivers about their children's future in marriage and career, emphasizing genetic risks.

Conclusions

In settings where dementia-specific community care services and primary healthcare professionals are limited and unevenly distributed, integrating support services at both the primary and community levels is crucial for families dealing with YOD in the community. Additionally, raising public awareness about YOD can foster a more understanding and supportive environment, addressing challenges related to stigma faced by affected families, contributing to increased investment in supporting resources, and encouraging individuals to seek help early on.

Comparing survival and mortality in patients with late-onset and young-onset vascular dementia

OBJECTIVES

Vascular dementia (VD) is one of the more common types of dementia. Much is known about VD in older adults in terms of survival and associated risk factors, but comparatively less is known about VD in a younger population. This study aimed to investigate survival in people with young-onset VD (YO-VD) compared to those with late-onset VD (LO-VD) and to investigate predictors of mortality.

DESIGN

Retrospective file review from 1992 to 2014.

SETTING

The inpatient unit of a tertiary neuropsychiatry service in Victoria, Australia.

PARTICIPANTS

Inpatients with a diagnosis of VD.

MEASUREMENTS AND METHODS

Mortality information was obtained from the Australian Institute of Health and Welfare. Clinical variables included age of onset, sex, vascular risk factors, structural neuroimaging, and Hachinksi scores. Statistical analyses used were Kaplan-Meier curves for median survival and Cox regression for predictors of mortality.

RESULTS

Eighty-four participants were included with few clinical differences between the LO-VD and YO-VD groups. Sixty-eight (81%) had died. Median survival was 9.9 years (95% confidence interval 7.9, 11.7), with those with LO-VD having significantly shorter survival compared to those with YO-VD (6.1 years and 12.8 years, respectively) and proportionally more with LO-VD had died (94.6%) compared to those with YO-VD (67.5%), χ2(1) = 9.16, p = 0.002. The only significant predictor of mortality was increasing age (p = 0.001).

CONCLUSION

While there were few clinical differences, and older age was the only factor associated with survival, further research into the effects of managing cardiovascular risk factors and their impact on survival are recommended.

Journey to Diagnosis of Young-Onset Dementia: A Qualitative Study of People with Young-Onset Dementia and their Family Caregivers in Australia

OBJECTIVES

This study aims to explore the journey to dementia diagnosis and reaction to the diagnosis from the perspective of people with young-onset dementia living in the community from diverse areas in Australia (metropolitan, regional, rural) and their family caregivers.

METHODS

Semi-structured interviews were conducted with community-dwelling people with early to moderate young-onset Alzheimer's disease (n = 8) or frontotemporal dementia (n = 5) and one person with both Alzheimer's disease and frontotemporal dementia, and family caregivers of community-dwelling people with young-onset Alzheimer's disease and/or frontotemporal dementia (n = 28). This study employed interpretive description. Thematic analysis was conducted for emergent themes, comparisons and interplay between themes.

FINDINGS

The journey to the diagnosis is characterised as involving an extensive period of the gradual worsening of symptoms, drawn out investigations, and difficulties facing the prospect of a diagnosis of young-onset dementia. Participants with young-onset dementia struggled to manage their symptoms and the process of seeking a diagnosis was often slow due to difficulties during the course of their medical investigations and feeling reluctance to face the possibility of having dementia. Once participants finally received the diagnosis of young-onset dementia, participants with young-onset dementia and their family caregivers experienced feelings of devastation and shock, in some cases denial and avoidance, and even, confirmation and relief at having received a diagnosis. In some instances, participants experienced more than one of these reactions. There was a profound realisation by participants that a diagnosis of young-onset dementia had serious implications on their life and future.

CONCLUSION

The journey to diagnosis was found to be a drawn-out process and receiving the diagnosis was a shock for both people with young-onset dementia and their family caregivers. The findings highlight the significance of the role healthcare professionals play in both the diagnostic and post-diagnostic journey, particularly in terms of supporting patients with young-onset dementia and their family caregivers.

A thematic analysis of psychotic symptoms in young-onset dementia

OBJECTIVES

Exploration of the themes and content of psychotic symptoms in young-onset dementia (YOD) is limited to case analysis. The primary objective of this study was to determine the themes of psychotic symptoms in individuals diagnosed with YOD.

DESIGN

Comprehensive retrospective file review of discharge summaries.

SETTING

Neuropsychiatry, a specialist mental health service located at the Royal Melbourne Hospital, Australia.

PARTICIPANTS

Inpatients at Neuropsychiatry admitted between 2018 and 2020 (inclusive).

MEASUREMENTS

Data extracted included descriptions and prevalence of psychotic symptoms as well as general demographic and clinical data. Data analysis was conducted using a thematic approach.

RESULTS

Twenty-three inpatients had a diagnosis of YOD with psychotic symptoms. Themes were identified in the domains of delusions (six themes), auditory hallucinations (five themes), and visual hallucinations (two themes). Strong recurring themes across the modalities of hallucinations and delusions were beliefs and experiences relating to paranoia, suspicion, harm, and abuse. Themes did not clearly intersect across the modalities of hallucinations and delusions. A degree of thematic heterogeneity existed within individuals, and individuals experienced delusions or hallucinations of multiple themes. The themes of the psychotic symptoms did not clearly relate to diagnostic category, nor to time from diagnosis.

CONCLUSION

This study is the first thematic analysis of psychotic symptoms in YOD and provides further understanding of patient phenomenology and experiences of psychosis in YOD.

Young-onset dementia diagnosis, management and care: a narrative review

Young-onset dementia comprises a heterogeneous range of dementias, with onset at less than 65 years of age. These include primary dementias such as Alzheimer disease, frontotemporal and vascular dementias; genetic/familial dementias; metabolic disorders; and secondary dementias such as those that result from alcohol use disorder, traumatic brain injury, and infections. The presentation of young-onset dementia is varied and may include cognitive, psychiatric and neurological symptoms. Diagnostic delay is common, with a frequent diagnostic conundrum being, "Is this young-onset dementia or is this psychiatric?". For assessment and accurate diagnosis, a thorough screen is recommended, such as collateral history and investigations such as neuroimaging, lumbar puncture, neuropsychology, and genetic testing. The management of young-onset dementia needs to be age-appropriate and multidisciplinary, with timely access to services and consideration of the family (including children).

Recent research advances in young-onset dementia

PURPOSE OF REVIEW

Young-onset dementia (YOD) refers to a dementia for which symptom onset occurs below the age of 65. This review summarizes the recent literature in this area, focusing on updates in epidemiology, diagnosis and service provision.

RECENT FINDINGS

In the last year, internationally, the prevalence of YOD was reported as 119 per 100 000, but this may vary according to population types. Although the commonest causes of YOD are Alzheimer's disease (AD) and frontotemporal dementia (FTD), there is increasing recognition that YOD is diagnostically and phenotypically broader than AD and FTD. YOD may be due to many other diseases (e.g. Huntington's disease, vascular dementia) whereas accumulation of the same protein (e.g. amyloid protein) may lead to different phenotypes of Alzheimer's disease (such as posterior cortical atrophy and behavioural-variant/frontal-variant AD). This heterogeneity of phenotypic presentation is also seen in YOD due to known genetic mutations. Biomarkers such as plasma and cerebrospinal fluid proteins, neuroimaging and genetics have shown promise in the early identification of YOD as well as providing further understanding behind the overlap between psychiatric and neurodegenerative conditions occurring in younger people. The management of YOD needs to consider age-specific issues for younger people with dementia and their family networks together with better integration with other health services such as aged, disability and improved access to services and financial assistance.

SUMMARY

These findings emphasize the need for early identification and appropriate age-specific and person-centred management for people with young-onset dementia.

Carer burden and behavioral disturbance is similar between younger-onset Alzheimer's disease and behavioral variant frontotemporal dementia

OBJECTIVES

Carer burden is common in younger-onset dementia (YOD), often due to the difficulty of navigating services often designed for older people with dementia. Compared to Alzheimer's disease (AD), the burden is reported to be higher in behavioral variant frontotemporal dementia (bvFTD). However, there is little literature comparing carer burden specifically in YOD. This study hypothesized that carer burden in bvFTD would be higher than in AD.

DESIGN

Retrospective cross-sectional study.

SETTING

Tertiary neuropsychiatry service in Victoria, Australia.

PARTICIPANTS

Patient-carer dyads with YOD.

MEASUREMENTS

We collected patient data, including behaviors using the Cambridge Behavioral Inventory-Revised (CBI-R). Carer burden was rated using the Zarit Burden Inventory-short version (ZBI-12). Descriptive statistics and Mann-Whitney U tests were used to analyze the data.

RESULTS

Carers reported high burden (ZBI-12 mean score = 17.2, SD = 10.5), with no significant difference in burden between younger-onset AD and bvFTD. CBI-R stereotypic and motor behaviors, CBI-R everyday skills, and total NUCOG scores differed between the two groups. There was no significant difference in the rest of the CBI-R subcategories, including the behavior-related domains.

CONCLUSION

Carers of YOD face high burden and are managing significant challenging behaviors. We found no difference in carer burden between younger-onset AD and bvFTD. This could be due to similarities in the two subtypes in terms of abnormal behavior, motivation, and self-care as measured on CBI-R, contrary to previous literature. Clinicians should screen for carer burden and associated factors including behavioral symptoms in YOD syndromes, as they may contribute to carer burden regardless of the type.

System and policy-level barriers and facilitators for timely and accurate diagnosis of young onset dementia

OBJECTIVE

The multiyear diagnostic journey for young onset dementia (YOD) is fraught with clinical and personal difficulties and poses significant uncertainty for people living with YOD and their families. Most existing research has examined the personal and/or clinical barriers to a timely diagnosis of YOD, but less evidence exists regarding system level factors. The aim of this study is to investigate health professionals' insights for a timely and accurate YOD diagnosis at the system level.

DESIGN

Grounded theory qualitative study.

SETTING AND PARTICIPANTS

Semi-structured in-depth interviews with 11 health professionals working across varied healthcare settings were conducted online via videoconference.

MEASUREMENTS

Data were contrasted and compared within and between transcripts using the constant comparative method.

RESULTS

Seven themes emerged about barriers and facilitators for timely and accurate diagnosis of YOD: (1) stigma and awareness of YOD; (2) mismatched policy; (3) fractured health system; (4) inadequate pathways for YOD diagnostic care; (5) effective use of General Practitioners; (6) inequitable access and fragmented service navigation; (7) diverse and marginalised groups.

CONCLUSION

A complex web of systemic and system level barriers contributes to the delay of accurate and timely diagnosis for YOD. Diverse and marginalised groups experience greater inequitable disadvantage regarding YOD diagnostic care. There is an urgent need to focus on YOD diagnosis facilitators at the broader health system level.

Cross-sector learning collaboratives can improve post-diagnosis care integration for people with young onset dementia

Post-diagnosis young onset dementia (YOD) care is often fragmented, with services delivered across aged care, healthcare, and social care sectors. The aim of this project was to test the feasibility and potential effectiveness of a learning collaborative implementation strategy for improving the cross-sector integration of care for people with YOD and to generate data to refine the implementation strategy for scaleup. We conducted a longitudinal mixed methods process evaluation and recruited one representative from three Australian aged care organisations, three disability care organisations and three organisations (n = 9) contracted to deliver care navigation services. One representative from each organisation joined a learning collaborative within their local area and completed a six-module online education package incorporating written resources, webinars, collaboration and expert mentoring. Participants identified gaps in services in their region and barriers to care integration and developed a shared plan to implement change. Normalisation Process Theory was applied to understand the acceptability, penetration and sustainability of the implementation strategy as well as barriers and enabling factors. Dementia knowledge measured by the Dementia Knowledge and Awareness Scale was high among the professionals at the start of the implementation period (mean = 39.67, SD = 9.84) and did not change by the end (mean = 39.67, SD = 8.23). Quantitative data demonstrated that clinicians dedicated on average half of the recommended time commitment to the project. However, qualitative data identified that the learning collaborative strategy enhanced commitment to implementing integrated care and promoted action towards integrating previously disparate care services. Participant commitment to the project was influenced by their sense of obligation to their team, and teams that established clear expectations and communication strategies early were able to collaborate and use the implementation plan more effectively (demonstrating collective action). Teams were less likely to engage in the collective action or reflexive monitoring required to improve care integration if they did not feel engaged with their learning collaborative. Learning collaboratives hold promise as a strategy to improve cross-sector service collaboration for people with YOD and their families but must maximise group cohesion and shared commitment to change.

Incidence of Young Onset Dementia in Waikato, New Zealand: A Population-Based Study

Background: There is limited epidemiological research on the incidence of young onset dementia (YOD). Estimates of YOD incidence in New Zealand are extrapolated from international studies that do not reflect New Zealand’s population and ethnic diversity. Objective: To determine the incidence of YOD in the geographical area served by the Waikato District Health Board Methods: All new inpatient and outpatient in the age range 30–64 years with a documented diagnosis of dementia at Waikato Hospital between 1 January 2014 –31 December 2016 were identified. Incidence rates were calculated by 5-year age-band, sex, and ethnicity. Results: 64 incident cases of YOD were included. Incidence rates for all cause YOD were 13.3 (95% CI 10.3–17.0) and 22.7 (95% CI 17.5–29.1) per 100,000 person-years in the age range 30–64 years and 45–64 years respectively. The incidence rate in Māori (20.0, 95% CI 11.4–32.4) was higher compared to non-Māori (12.0, 95% CI 8.9–15.9), but this difference was not statistically significant (p = 0.09). Conclusion: The incidence of YOD in this study is similar to global estimates. Incidence may be higher in Māori compared to non-Māori, highlighting the need for culturally appropriate approaches to dementia prevention, intervention, and care.

Prevalence of young-onset dementia: nationwide analysis of routinely collected data

INTRODUCTION

Young-onset dementia prevalence is understudied internationally. Previous studies have been limited by low case numbers, reliance on single sources of routinely collected health data for case identification and inclusion of a limited age range. Our objective was to determine the 1-year period prevalence of diagnosed dementia in people aged 0-64 in the entire New Zealand population using routinely collected health data.

METHODS

A population-based descriptive study was carried out in New Zealand (population 4.8 million) using routinely collected deidentified health data from 2016 to 2020. Dementia cases in seven linked health datasets in the New Zealand Integrated Data Infrastructure were identified using diagnostic codes and/or use of antidementia medication. Prevalence for each of the four study years was calculated by age, sex and ethnicity.

RESULTS

From a total population of 4 027 332-4 169 754 individuals aged 0-64, we identified 3396-3474 cases of 'all-cause' dementia in each of the study years (prevalence crude range: 83-84/100 000 people aged 0-64; 139-141/100 000 people aged 30-64 years; 204-207/100 000 people aged 45-64 years). Age-standardised prevalence was higher in males than females. Age-standardised and sex-standardised prevalence was higher in Māori and Pacific People than European and Asian.

DISCUSSION

By using a large study population and multiple national health datasets, we have minimised selection bias and estimated the national prevalence of diagnosed young-onset dementia with precision. Young-onset dementia prevalence for the total New Zealand population was similar to reported global prevalence, validating previous estimates. Prevalence differed by ethnicity, which has important implications for service planning.

Carer burden and psychological distress in young-onset dementia: An Australian perspective

OBJECTIVES

Carer burden in dementia is associated with poor outcomes, including early nursing home placement for people with dementia and psychological distress for their carers. Carers of people with young-onset dementia (YOD) are particularly vulnerable to carer burden. Yet they are often overlooked by clinicians as dementia services are generally designed for older people. We sought to estimate the rate of burden and psychological distress in carers of YOD at a state-wide tertiary service based in Australia.

METHODS

We conducted a cross-sectional study examining 71 dyads from a Neuropsychiatry service. We collected patient demographic and clinical data including the Neuropsychiatry Unit Cognitive Assessment tool (NUCOG) and Mini-Mental State Examination (MMSE). Carer data, such as demographics and psychological distress, were obtained using Depression Anxiety Stress Scale 21 (DASS-21). Carer burden was rated using the Zarit Burden Inventory-short version (ZBI).

RESULTS

Higher carer burden, measured using ZBI, was associated with longer duration of dementia and greater severity of overall cognitive impairment. Carers who felt burdened reported higher levels of stress, depression, and anxiety measured using DASS-21. Multiple linear regression analysis found carer burden was independently predicted by duration of dementia, total cognition score and carers experiencing psychological stress.

DISCUSSION

We found that patient variables of dementia duration and cognitive impairment and carer variable of carer stress to be associated with carer burden. Poor executive function was associated with carer stress. Early identification and management of carer burden and psychological distress is important for outcomes. Ideally, this should be provided by a specialist YOD service.

Reimagining Postdiagnostic Care and Support in Young-Onset Dementia

Although dementia has a profound impact in general, young-onset dementia causes additional problems and challenges as people are affected in their prime years. Awareness has increased that people with young-onset dementia and their families have specific care needs and dedicated services are necessary to accommodate those needs. However, in many countries, age-appropriate care and support for people with young-onset dementia is still largely unavailable. In this special article, barriers as well as facilitators for the development of postdiagnostic care and support in young-onset dementia are addressed. Drawing from the experiences in the Netherlands, the establishment of an appropriate infrastructure has proven a corner stone in service development in young-onset dementia. The establishment of a center at the national level for the development and dissemination of knowledge and affiliated regional centers that coordinate and offer care and support at the regional level has helped to reimagine, redefine, but more importantly also rearrange, postdiagnostic care and support in young-onset dementia in the Netherlands. This has resulted in care standards for service provision in young-onset dementia that have been incorporated in the dementia standard at the national level. Also, a quality hallmark has been developed to guide the arrangement of age-appropriate services at the local level. Moreover, specific training programs are in place for health care professionals involved in young-onset dementia. To be able to prioritize topics in research for the upcoming years, a scientific agenda has been established. The strong collaboration between organizations that provide a voice for people with dementia, care providers and research centers, that all strive to support people to live well with young-onset dementia has boosted these developments and may inspire other countries searching for ways to improve postdiagnostic care and support in young-onset dementia.
