Time to diagnosis in younger-onset dementia and the impact of a specialist diagnostic service

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.

'Too young to sit at home': a qualitative study conducted among employees with young-onset dementia and their relatives

OBJECTIVES

Young-onset dementia (YOD) symptoms often first present in the workplace, resulting in work performance challenges and eventually loss of employment. This study aims to investigate the experiences, work values, and support needs of employees with YOD and their relatives.

METHOD

Semi-structured interviews were conducted to explore the experiences, work values, and support needs of (former) employees with YOD and their relatives. Subsequently, separate focus group discussions were conducted for employees and relatives to review and prioritize interview findings. Inductive thematic analysis was applied to both datasets.

RESULTS

A total of 15 interviews (six employees; nine relatives) and four focus group discussions (ten employees; six relatives) were conducted. Six themes emerged, with five revolving around the central theme: desire to work. The other themes represent essential contributing factors, including importance of receiving a YOD diagnosis; knowledge, awareness, and understanding regarding YOD; open communication, joint decision making, and collaboration; work adjustments, involvement, and support; phasing out work and future perspectives.

CONCLUSION

The findings highlight a strong desire to work post-YOD diagnosis, serving as a foundation for developing workplace support tools and guidance. This has the potential to help individuals with YOD preserve their self-confidence and identity while working within their capabilities.

Factors associated with the quality of life of persons with young-onset dementia: A systematic literature review

This review examines factors associated with quality of life (QoL) in persons with young-onset dementia (YOD). Studies investigating and analysing factors related to QoL in persons with YOD were included. Databases searched included PubMed, CINAHL, Web of Science, EMBASE, and SCOPUS. Due to inconsistent outcome variables across studies, synthesis without meta-analysis was used for data integration. Methodological quality was assessed, and results were synthesised. Eleven studies were included in this review, identifying different factors influencing QoL in persons with YOD, which could be categorised into six groups. Behavioural and psychiatric factors showed the highest significant findings ratio (SFR), as determined by the ratio of 'studies finding significance' to the 'total number of studies addressing the factor'. Following in terms of SFR were care-related and physical factors. Demographic and dementia-characteristic factors had the lowest SFR. Among single factors, depressive symptoms, and neuropsychiatric symptoms, both included in behavioural and psychiatric factors, had the highest SFR. This systematic review highlights the importance of behavioural and psychiatric elements in QoL in persons with young onset and points to depressive symptoms and neuropsychiatric symptoms as potential therapeutic targets. However, as research on QoL in persons with YOD continues to expand, the inclusion of methods such as meta-analysis may be beneficial.

Time to Diagnosis and Its Predictors in Syndromes Associated With Frontotemporal Lobar Degeneration

OBJECTIVES

Frontotemporal Lobar Degeneration (FTLD) causes a heterogeneous group of neurodegenerative disorders with a wide range of clinical features. This might delay time to diagnosis. The aim of the present study is to establish time to diagnosis and its predictors in patients with FTLD-associated syndromes.

DESIGN

Retrospective study.

SETTING

Tertiary referral center.

PARTICIPANTS

A total of 1029 patients with FTLD-associated syndromes (age: 68 [61-73] years, females: 46%) from 1999 to 2023 were included in the present study.

MEASUREMENTS

Time to diagnosis was operationalized as the time between symptom onset and the diagnosis of a FTLD-associated syndrome. The associations between time to diagnosis and possible predictors (demographic and clinical variables) were investigated through univariate and multivariate linear models.

RESULTS

Median time to diagnosis was 2 [1-3] years. We observed that younger age at onset (β = -0.03, p <0.001), having worked as a professional rather than as a blue (β = 0.52, p = 0.024) or a white (β = 0.46, p = 0.050) collar, and having progressive supranuclear palsy (p <0.05) or the semantic variant of primary progressive aphasia (p <0.05) phenotypes were significantly associated with increased time to diagnosis. No significant changes of time to diagnosis have been observed over 20 years.

CONCLUSIONS

The identification of predictors of time to diagnosis might improve current diagnostic algorithms, resulting in a timely initiation of symptomatic treatments, early involvement in clinical trials, and more adequate public health policies for patients and their families.

Cerebrospinal fluid neurofilament light predicts longitudinal diagnostic change in patients with psychiatric and neurodegenerative disorders

OBJECTIVE

People with neuropsychiatric symptoms often experience delay in accurate diagnosis. Although cerebrospinal fluid neurofilament light (CSF NfL) shows promise in distinguishing neurodegenerative disorders (ND) from psychiatric disorders (PSY), its accuracy in a diagnostically challenging cohort longitudinally is unknown.

METHODS

We collected longitudinal diagnostic information (mean = 36 months) from patients assessed at a neuropsychiatry service, categorising diagnoses as ND/mild cognitive impairment/other neurological disorders (ND/MCI/other) and PSY. We pre-specified NfL > 582 pg/mL as indicative of ND/MCI/other.

RESULTS

Diagnostic category changed from initial to final diagnosis for 23% (49/212) of patients. NfL predicted the final diagnostic category for 92% (22/24) of these and predicted final diagnostic category overall (ND/MCI/other vs. PSY) in 88% (187/212), compared to 77% (163/212) with clinical assessment alone.

CONCLUSIONS

CSF NfL improved diagnostic accuracy, with potential to have led to earlier, accurate diagnosis in a real-world setting using a pre-specified cut-off, adding weight to translation of NfL into clinical practice.

Investigating Equivalence of In-Person and Telehealth-Based Neuropsychological Assessment Performance for Individuals Being Investigated for Younger Onset Dementia

OBJECTIVE

Given the rapid shift to in-home teleneuropsychology models, more research is needed to investigate the equivalence of non-facilitator models of teleneuropsychology delivery for people with younger onset dementia (YOD). This study aimed to determine whether equivalent performances were observed on neuropsychological measures administered in-person and via teleneuropsychology in a sample of people being investigated for YOD.

METHOD

Using a randomized counterbalanced cross-over design, 43 participants (Mage = 60.26, SDage = 7.19) with a possible or probable YOD diagnosis completed 14 neuropsychological tests in-person and via teleneuropsychology, with a 2-week interval. Repeated measures t-tests, intraclass correlation coefficients (ICC), and Bland Altman analyses were used to investigate equivalence across the administration conditions.

RESULTS

No statistical differences were found between in-person and teleneuropsychology conditions, except for the Hospital Anxiety and Depression Scale Anxiety subtest. Small to negligible effect sizes were observed (ranging from .01 to .20). ICC estimates ranged from .71 to .97 across the neuropsychological measures. Bland Altman analyses revealed that the Wechsler Adult Intelligence Scale-Fourth Edition Block Design subtest had slightly better overall performance in the in-person condition and participants reported higher levels of anxiety symptoms during the teleneuropsychology condition; however, average anxiety symptoms remained within the clinically normal range. Participants reported a high level of acceptability for teleneuropsychology assessments.

CONCLUSIONS

These results suggest that performances are comparable between in-person and teleneuropsychology assessment modalities. Our findings support teleneuropsychology as a feasible alternative to in-person neuropsychological services for people under investigation of YOD, who face significant barriers in accessing timely diagnoses and treatment options.

Plasma neurofilament light in behavioural variant frontotemporal dementia compared to mood and psychotic disorders

OBJECTIVE

Blood biomarkers of neuronal injury such as neurofilament light (NfL) show promise to improve diagnosis of neurodegenerative disorders and distinguish neurodegenerative from primary psychiatric disorders (PPD). This study investigated the diagnostic utility of plasma NfL to differentiate behavioural variant frontotemporal dementia (bvFTD, a neurodegenerative disorder commonly misdiagnosed initially as PPD), from PPD, and performance of large normative/reference data sets and models.

METHODS

Plasma NfL was analysed in major depressive disorder (MDD, n = 42), bipolar affective disorder (BPAD, n = 121), treatment-resistant schizophrenia (TRS, n = 82), bvFTD (n = 22), and compared to the reference cohort (Control Group 2, n = 1926, using GAMLSS modelling), and age-matched controls (Control Group 1, n = 96, using general linear models).

RESULTS

Large differences were seen between bvFTD (mean NfL 34.9 pg/mL) and all PPDs and controls (all < 11 pg/mL). NfL distinguished bvFTD from PPD with high accuracy, sensitivity (86%), and specificity (88%). GAMLSS models using reference Control Group 2 facilitated precision interpretation of individual levels, while performing equally to or outperforming models using local controls. Slightly higher NfL levels were found in BPAD, compared to controls and TRS.

CONCLUSIONS

This study adds further evidence on the diagnostic utility of NfL to distinguish bvFTD from PPD of high clinical relevance to a bvFTD differential diagnosis, and includes the largest cohort of BPAD to date. Using large reference cohorts, GAMLSS modelling and the interactive Internet-based application we developed, may have important implications for future research and clinical translation. Studies are underway investigating utility of plasma NfL in diverse neurodegenerative and primary psychiatric conditions in real-world clinical settings.

Perceived barriers and solutions by generalist physicians to work towards timely young-onset dementia diagnosis

Objectives: Timely diagnosis of young-onset dementia (YOD) is an important prerequisite to initiate appropriate support. However, YOD diagnosis is often late. We aimed to explore the perspectives of referring general practitioners and occupational physicians, to better understand their barriers to YOD diagnosis and reveal potential solutions to facilitate timely diagnosis.Methods: We conducted 16 semi-structured qualitative interviews with general practitioners and occupational physicians in the Netherlands. Inductive thematic analysis was applied to the transcripts with a team including researchers from various (clinical) backgrounds.Results: Thematic analysis revealed three themes related to: (1) disease characteristics that hinder YOD recognition, being the low incidence and the fact that they mimic other prevalent conditions like burn-out and depression; (2) physicians' attitudes that delay YOD diagnosis, as fear of mis-diagnosis and therapeutic nihilism; and (3) proposed solutions to navigate the challenging YOD diagnostic trajectory including monitoring people with depression and burn-out to consider YOD when recovery stagnates, and more effective interprofessional collaboration.Conclusion: In this study, referring physicians confirmed barriers known to YOD diagnosis and suggested potential solutions to improve YOD diagnosis. Future prospective studies in people with a primary diagnosis of depression or burn-out may show whether these interventions are potentially effective.

Autonomic modulation and the risk of dementia in a middle-aged cohort: A 17-year follow-up study

BACKGROUND

Altered autonomic modulation, measured by heart rate variability (HRV), has been found to be associated with dementia risk in the elderly. However, long-term follow-up study evaluating the association between autonomic modulation from middle-age and the incidence of dementia has been limited.

METHODS

This retrospective cohort analyzed data from Taiwan's National Health Insurance Database covering the period from 2001 to 2017, with a linkage to citywide health examinations conducted by Tainan Metropolitan City, Taiwan. We included subjects aged 45-64 years. The mean follow-up period was 15.75 ± 3.40 years. The measurements of HRV included resting heart rate, high frequency (HF), low frequency (LF), standard deviation of normal-to-normal R-R intervals (SDNN), ratio between the 30th and 15th R-R interval after standing up from the supine position (30/15 ratio), ratio between the R-R intervals during expiration and inspiration, and the ratio between the high- and low-frequency components (LF/HF). The main study outcome was the incidence of dementia. We performed multivariable Cox proportional hazard regression models to compare the risk of dementia among different HRV subgroups.

RESULTS

We included 565 participants with a mean age of 53 (SD: 6) years, of whom 44% were male. The risk of dementia was significantly increased in association with lower parasympathetic HRV modulation, including SDNN (HR: 3.23, 95% CI: 1.55-6.73) and 30/15 ratio (HR: 3.52, 95%CI: 1.67-7.42). Moreover, the risk of dementia was increased in subjects with higher LF/HF ratios (HR: 2.05, 95% CI: 1.12-3.72).

CONCLUSIONS

Lower parasympathetic activity and higher sympathetic-vagal imbalance in middle-age were associated with dementia risk.

Online peer support: views and experiences of people with young onset dementia (YOD)

OBJECTIVES

This study explores (1) which platforms people with YOD use for online peer support, (2) reasons for using or not using online peer support, and (3) how to optimise potential benefits and accessibility.

METHODS

A mixed-methods online survey was conducted including fixed-choice and open questions. Participants were people with YOD recruited through dementia organisations, Join Dementia Research and the NHS using convenience sampling. Fixed-choice questions were analysed with Chi-square test of significance and free-text responses with thematic analysis.

RESULTS

A total of 69 completed surveys were analysed. Zoom was most popular for online peer support, followed by Facebook and Twitter. Positives included sharing social support, joining from home, and the option to choose a preferred platform. However, it can be difficult to follow the conversation or understand others. Many were unaware about online peer support and some felt uncomfortable talking to strangers online. To improve access and benefits of online peer support organisations and healthcare professionals should advertise and signpost more and groups should have a clear description.

CONCLUSION

Online platforms facilitate social support and make peer support accessible to those who do not have access to in-person options. Future research and practice should focus on raising awareness about online peer support.

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.

Clinical characteristics of early-onset versus late-onset Alzheimer's disease: a systematic review and meta-analysis

OBJECTIVES

A number of studies have compared Alzheimer's disease (AD), the commonest form of dementia, based on their age of onset, i.e. before the age of 65 years (early-onset AD, EO-AD) to those developing after 65 years of age (late-onset AD, LO-AD), but the differences are not clear. We performed a systematic review and meta-analysis to compare clinical characteristics between EO-AD and LO-AD.

DESIGN, MEASUREMENTS, AND PARTICIPANTS

Medline, Embase, PsycINFO, and CINAHL databases were systematically searched for studies comparing time to diagnosis, cognitive scores, annual cognitive decline, activities of daily living (ADLs), neuropsychiatric symptoms (NPS), quality of life (QoL), and survival time for EO-AD and LO-AD patients.

RESULTS

Forty-two studies were included (EO-AD participants n = 5,544; LO-AD participants n = 16,042). An inverse variance method with random effects models was used to calculate overall effect estimates for each outcome. People with EO-AD had significantly poorer baseline cognitive performance and faster cognitive decline but longer survival times than people with LO-AD. There was no evidence that EO-AD patients differ from people with LO-AD in terms of symptom onset to diagnosis time, ADLs, and NPS. There were insufficient data to estimate overall effects of differences in QoL in EO-AD compared to LO-AD.

CONCLUSIONS

Our findings suggest that EO-AD differs from LO-AD in baseline cognition, cognitive decline, and survival time but otherwise has similar clinical characteristics to LO-AD. Larger studies using standardized questionnaires focusing on the clinical presentations are needed to better understand the impact of age of onset in AD.

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.

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.

Delay in the diagnosis of dementia in urban India: Role of dementia subtype and age at onset

BACKGROUND

Early diagnosis of dementia is crucial for timely intervention. However, frequently, there is a substantial delay in diagnosis. Therefore, it is essential to recognise and address the barriers to early diagnosis. These have not been systematically studied in India. We at a specialist memory clinic in India investigated the time from symptom onset to diagnosis of dementia and factors contributing to the delay.

METHODS

In this cross-sectional study, consecutive patients with dementia (n = 855) seen at a private hospital underwent a standard clinical assessment and investigations. The primary outcome variable was time from symptom onset to diagnosis (TTD). The association of age, education, gender, dementia subtype, and age of onset on TTD were examined using a univariate analysis of covariance.

RESULTS

The median TTD was 24 months; 43% were diagnosed after 24 months. There was a significant association between TTD and age at onset (young onset-median 36 months vs. late onset-24 months) and dementia subtype. Patients with vascular dementia were diagnosed significantly earlier as compared to patients with Alzheimer's disease (AD) and frontotemporal dementia (FTD) [median 18, 24, and 30 months, respectively]. There was no effect of gender or education on the TTD.

CONCLUSION

About 40% of patients with dementia were diagnosed more than 2 years after symptom onset, particularly young onset dementias and FTD. Our study findings highlight the gaps in diagnosing patients with dementia in urban India and have significant implications for developing and implementing multifaceted interventions to improve the early diagnosis of dementia.

Understanding Clinician's Experiences with Implementation of a Younger Onset Dementia Telehealth Service

The successful implementation of telehealth services depends largely on clinician acceptance of telehealth as a viable healthcare option and their adoption of telehealth methods into their clinical practice. While growing research supports the feasibility of telehealth services, no research has evaluated clinicians' experiences during the implementation of a younger onset dementia telehealth service. Semi-structured group interviews were conducted with 7 metropolitan (hub) clinicians and 16 rural (spoke) clinicians during the pre-and post-implementation phases of a novel Younger onset dementia (YOD) telehealth service. Reflexive thematic analysis identified five themes at pre-implementation: clinical need, previous experiences and views, potential telehealth barriers, solutions to potential telehealth barriers, and potential clinical outcomes. At post-implementation, nine themes were identified: clinical need, clinical relationships, concerns about the future of rural healthcare, clinical practice and resourcing factors, patient suitability, difficulties with technology, service quality, the way forward, and the impact of COVID-19. Most clinicians held positive views regarding the service, particularly the ability to provide more options to rural-dwelling patients. However, some concerns about threats to rural healthcare and the validity of telehealth assessments remained. Overall, this study has identified service implementation barriers and facilitators and contributes to the long-term sustainability of current and future telehealth YOD services.

How Telemedicine Can Improve the Quality of Care for Patients with Alzheimer's Disease and Related Dementias? A Narrative Review

Background and Objectives: Dementia affects more than 55 million patients worldwide, with a significant societal, economic, and psychological impact. However, many patients with Alzheimer's disease (AD) and other related dementias have limited access to effective and individualized treatment. Care provision for dementia is often unequal, fragmented, and inefficient. The COVID-19 pandemic accelerated telemedicine use, which holds promising potential for addressing this important gap. In this narrative review, we aim to analyze and discuss how telemedicine can improve the quality of healthcare for AD and related dementias in a structured manner, based on the seven dimensions of healthcare quality defined by the World Health Organization (WHO), 2018: effectiveness, safety, people-centeredness, timeliness, equitability, integrated care, and efficiency. Materials and Methods: MEDLINE and Scopus databases were searched for peer-reviewed articles investigating the role of telemedicine in the quality of care for patients with dementia. A narrative synthesis was based on the seven WHO dimensions. Results: Most studies indicate that telemedicine is a valuable tool for AD and related dementias: it can improve effectiveness (better access to specialized care, accurate diagnosis, evidence-based treatment, avoidance of preventable hospitalizations), timeliness (reduction of waiting times and unnecessary transportation), patient-centeredness (personalized care for needs and values), safety (appropriate treatment, reduction of infection risk),integrated care (interdisciplinary approach through several dementia-related services), efficiency (mainly cost-effectiveness) and equitability (overcoming geographical barriers, cultural diversities). However, digital illiteracy, legal and organizational issues, as well as limited awareness, are significant potential barriers. Conclusions: Telemedicine may significantly improve all aspects of the quality of care for patients with dementia. However, future longitudinal studies with control groups including participants of a wide educational level spectrum will aid in our deeper understanding of the real impact of telemedicine in quality care for this population.

Cerebrospinal fluid neurofilament light chain differentiates primary psychiatric disorders from rapidly progressive, Alzheimer's disease and frontotemporal disorders in clinical settings

INTRODUCTION

Many patients with cognitive and neuropsychiatric symptoms face diagnostic delay and misdiagnosis. We investigated whether cerebrospinal fluid (CSF) neurofilament light (NfL) and total-tau (t-tau) could assist in the clinical scenario of differentiating neurodegenerative (ND) from psychiatric disorders (PSY), and rapidly progressive disorders.

METHODS

Biomarkers were examined in patients from specialist services (ND and PSY) and a national Creutzfeldt-Jakob registry (Creutzfeldt-Jakob disease [CJD] and rapidly progressive dementias/atypically rapid variants of common ND, RapidND).

RESULTS

A total of 498 participants were included: 197 ND, 67 PSY, 161 CJD, 48 RapidND, and 20 controls. NfL was elevated in ND compared to PSY and controls, with highest levels in CJD and RapidND. NfL distinguished ND from PSY with 95%/78% positive/negative predictive value, 92%/87% sensitivity/specificity, 91% accuracy. NfL outperformed t-tau in most real-life clinical diagnostic dilemma scenarios, except distinguishing CJD from RapidND.

DISCUSSION

We demonstrated strong generalizable evidence for the diagnostic utility of CSF NfL in differentiating ND from psychiatric disorders, with high accuracy.

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.

Neuroimaging in the Acute Psychiatric Setting: Associations With Neuropsychiatric Risk Factors

OBJECTIVE

The appropriateness and clinical utility of neuroimaging in psychiatric populations has been long debated, and the ambiguity of guideline recommendations is well established. Most of the literature is focused on first-episode psychosis. The investigators aimed to review ordering practices and identify risk factors associated with neuroradiological MRI abnormalities and their clinical utility in a general psychiatric population.

METHODS

A retrospective file review was undertaken for 100 consecutive brain MRI scans for adult psychiatric inpatients who received scanning as part of their clinical care in an Australian hospital.

RESULTS

Brain MRI was abnormal in 79.0% of scans; in these cases, 72.2% of patients required further investigation or follow-up, with 17.7% requiring urgent referral within days to weeks, despite only 3.7% of admitted patients undergoing MRI during the study period. Psychiatrically relevant abnormalities were found in 32.0% of scans. Abnormalities were more likely to be found in the presence of cognitive impairment, older age, and longer duration of psychiatric disorder. Psychiatrically relevant abnormalities had further associations with older age at onset of the psychiatric disorder and a weak association with abnormal neurological examination. Multiple indications for imaging were present in 57.0% of patients; the most common indications were physical, neurological, and cognitive abnormalities.

CONCLUSIONS

Brain MRI is a useful part of psychiatric management in the presence of certain neuropsychiatric risk factors. The present findings suggest that treating teams can judiciously tailor radiological investigations while limiting excessive imaging. Future research in larger cohorts across multiple centers may contribute to shaping more consistent neuroimaging guidelines in psychiatry.

Music and Psychology & Social Connections Program: Protocol for a Novel Intervention for Dyads Affected by Younger-Onset Dementia

Psychosocial interventions targeting the specific needs of people affected by younger-onset dementia are lacking. Younger-onset dementia refers to dementia where symptom onset occurs at less than 65 years old. Because of its occurrence in middle age, the impact on spouses is particularly marked and dyadic-based interventions are recommended. Music And Psychology & Social Connections (MAPS) is a novel online intervention, informed by the theory of adaptive coping by Bannon et al. (2021) for dyads affected by younger-onset dementia. MAPS combines therapeutic songwriting, cognitive behaviour therapy, and a private social networking group that focuses on the dyads. This will be a randomised controlled trial with a waitlist control. The primary aims are to assess whether MAPS improves depressive, anxiety, and stress symptoms in caregivers, with secondary aims to assess whether MAPS improves depressive symptoms in people with younger-onset dementia. The trial also aims to assess dyadic social connectedness; caregiver coping skills; and neuropsychiatric symptoms in people with younger-onset dementia. We will recruit 60 dyads to participate in a group-based weekly online program for 8 weeks facilitated by a credentialed music therapist and psychologist. Sessions 1 and 8 will include both caregivers and people with younger-onset dementia and Sessions 2–7 will involve separate group sessions for caregivers and those with dementia. There will be focus groups for qualitative feedback. Due to its online administration, MAPS has the potential to reach many dyads affected by younger-onset dementia.

The role of Memory Clinics in the assessment and management of dementia, now and into the future

PURPOSE OF REVIEW

The diagnosis of dementia is often delayed and many individuals with the disorder go undiagnosed or receive an inadequate assessment. Specialist Memory Clinics have long been at the centre of such assessments. Recent developments in biomarkers and disease-modifying treatments are likely increase the need for specialist assessments. It is therefore timely to review the role of Memory Clinics internationally.

RECENT FINDINGS

The timely diagnosis of dementia and cognitive decline is the main responsibility of Memory Clinics. These clinics can diagnose dementia up to 4 years earlier than primary care services, but their low numbers and capacity of leads to long waiting times and a focus on complex cases. Few clinics are resourced to offer specific postdiagnostic support services, and their roles in clinical trials and research have not been realised. They are often well integrated with primary care and aged care services.

SUMMARY

Memory Clinics play an important role in bridging the gap between research and clinical practice and providing high-quality assessment and care. Additional Memory Clinic services and greater harmonisation of their responsibilities and procedures are needed to exploit their full potential.

Post-diagnosis young-onset dementia care in the National Disability Insurance Scheme

OBJECTIVE

Post-diagnosis service delivery for young-onset dementia (with onset prior to 65 years) recently moved to the disability system in an attempt to address systemic barriers to best practice in aged care. The objective of this study was to examine experiences and satisfaction with disability services so far among people with young-onset dementia and their care partners and identify strategies for service and system improvement.

METHODS

The 151 participating Australians living with young-onset dementia or providing informal care to a person with young-onset dementia were recruited via social media, advocacy bodies and specialist medical clinics. A cross-sectional online survey asked participants to provide a timeline of their interactions with the disability system so far and rate their satisfaction with the disability system, aged care and disability services.

RESULTS

Participants reported a mean age at symptom onset of 55 years. In all, 53% were diagnosed with Alzheimer's disease and 25% were diagnosed with frontotemporal dementia. Sixty percent had received an approved plan from the National Disability Insurance Scheme, although 3% were rejected. More than 27% waited longer than 6 months to receive their plan, and half waited at least a month post-approval to access services. Less than 30% agreed that the National Disability Insurance Scheme understands dementia, and fewer than half felt that the process of accessing National Disability Insurance Scheme funding is easy and fast enough. Nonetheless, respondents remained overwhelmingly in favour of young-onset dementia services remaining in the disability system rather than in aged care.

CONCLUSIONS

While people with young-onset dementia and their care partners strongly agree with their inclusion in the National Disability Insurance Scheme, a relatively low level of experience with dementia in the disability workforce and a lack of integration with the healthcare and aged care systems continue to create important barriers for accessing the services they need.

Age of Symptom Onset and Longitudinal Course of Sporadic Alzheimer's Disease, Frontotemporal Dementia, and Vascular Dementia: A Systematic Review and Meta-Analysis

BACKGROUND

Understanding how the age of dementia symptom onset affects the longitudinal course of dementia can assist with prognosis and care planning.

OBJECTIVE

To synthesize evidence regarding the relationship of age of symptom onset with the longitudinal course of sporadic Alzheimer's disease (AD), vascular dementia (VaD), and frontotemporal dementia (FTD).

METHODS

We searched Medline, CINAHL, Embase, PsycINFO, PubMed, and Scopus for longitudinal studies that examined the impact of sporadic AD, VaD, or FTD symptom onset age on measures of cognition, function, or behavioral symptoms. Studies that examined age at diagnosis only were excluded. Quantitative meta-analysis was conducted where studies reported sufficient data for pooling.

RESULTS

Thirty studies met all inclusion criteria (people with AD (n = 26), FTD (n = 4)) though no studies examined VaD. Earlier onset of AD was associated with more rapid annual cognitive decline (estimate = -0.07; 95% CI -0.14 to 0.00; p = 0.045). Most studies that stratified their sample reported that younger AD onset (usually <  65 years) was associated with more rapid cognitive decline. Other evidence was inconclusive.

CONCLUSION

Younger people with AD appear to have a poorer prognosis in terms of faster cognitive decline than older people with AD. More research is required to determine the impact of symptom onset age in VaD and FTD, and on functional decline in all dementias.

Risk factors to mortality and causes of death in frontotemporal dementia: An Australian perspective

OBJECTIVES

Frontotemporal dementia (FTD) is a common cause of dementia in younger people. There is less information known about risk factors to mortality such as the type of symptom onset and cause of death in this group.

METHOD

This was a retrospective file review of inpatients with FTD admitted to a tertiary neuropsychiatry unit located in Australia from 1992 to 2014. Mortality information including linkage of names and causes of death were obtained from the Australian Institute Health and Welfare National Death Index.

RESULTS

One hundred inpatients were diagnosed with FTD, including behavioural-variant, language-variant FTDs and FTD-motor neuron disease (FTD-MND). Mean age was 52.8 years (SD = 10, range 31-76 years). Sixty-seven of them had died at linkage. Median survival of the sample was 10.5 years and FTD-MND had the shortest survival, 3.5 years. Increasing age of onset and FTD-MND were found to be significant predictors of association for mortality. Compared to the general population, having a FTD had an 8× increased risk of death. Females had double the standardised mortality ratio compared to males.

DISCUSSION

This study provides important prognostic information for people diagnosed with FTD living in Australia. It highlights the importance of obtaining a definitive diagnosis as early as possible for future planning. More investigation into the relationship of symptom onset type and sex differences in FTD is required.

A Systematic Review of the Indirect and Social Costs in Early and Young Onset Dementias

BACKGROUND

The World Health Organization has estimated that worldwide around 50 million people have dementia. The World Alzheimer Report estimated that between 2 and 10% of all cases of dementia begin before the age of 65. Early and young onset dementias (EYOD) provoke more working, social, family, and economic consequences than late onset dementias. All general studies about costs of dementias show that most of them are indirect or social costs. Despite that, very few studies have been performed in EYOD.

OBJECTIVE

To do a systematic review of literature about indirect or social costs in EYOD to know the state of knowledge and to discover gaps that should be filled.

METHODS

A systematic review was performed in the main database: Scopus, PsychInfo, Web of Science (Web of Science Core Collection, Medline and SciELO), and CINAHL. Additionally, we looked for reviews in Cochrane and in the International Prospective Register Of Systematic Reviews (PROSPERO).

RESULTS

Most of the studies are about costs of dementias in general, but they do no differentiate costs for the case of EYOD. Many studies highlight the increased costs for EYOD but very little included evidence of that. 135 papers were selected. Finally, only two were studies providing data. EYOD reduce the odds to get or maintain a job. Most of the care is provided by informal caregivers. The costs in EYOD are 39.26% higher among EYOD than in late onset.

CONCLUSION

There is a lack of studies about social and indirect costs in EYOD. More evidence is needed.

Time to Diagnosis in Young Onset Alzheimer's Disease: A Population-Based Study from Central Norway

Background:

Young onset dementia is associated with a longer time to diagnosis compared to late onset dementia. Earlier publications have indicated that atypical presentation is a key contributing factor to the diagnostic delay. Our hypothesis was that even the most common presentation of Alzheimer’s disease is associated with a substantial diagnostic delay in patients < 65 years.

Objective:

To determine the time to diagnosis, and time lags in the diagnostic pathway in typical young onset Alzheimer’s disease in central Norway.

Methods:

The main sources of patients were the databases at the Department of Neurology, University Hospital of Trondheim (St. Olav’s Hospital), and Department of Psychiatry, Levanger Hospital. Other sources included key persons in the communities, collaborating hospital departments examining patients with suspected cognitive impairment, and review of hospital records of all three hospitals in the area. Information on the time lags, and the clinical assessment, including the use of biomarkers, was collected from hospital notes. Caregivers were interviewed by telephone.

Results:

Time from first symptom to diagnosis in typical young onset Alzheimer’s disease was 5.5 years (n = 223, SD 2.8). Time from onset to contact with healthcare services (usually a general practitioner) was 3.4 years (SD 2.3). Time from contact with healthcare services to the first visit at a hospital was 10.3 months (SD 15.5). Time from first visit at a hospital to diagnosis was 14.8 months (SD 22.6). The analysis of cerebrospinal fluid core biomarkers was performed after 8.3 months (SD 20.9).

Conclusion:

Typical Alzheimer’s disease is associated with a substantial diagnostic delay in younger patients. Raising public awareness, and education of healthcare professionals on the aspects of young onset Alzheimer’s disease is warranted. CSF core biomarkers should be performed earlier in the hospital evaluation process.

Socio-economic predictors of time to care home admission in people living with dementia in Wales: A routine data linkage study

OBJECTIVES

Limited research has shown that people with dementia (PwD) from lower socio-economic backgrounds can face difficulties in accessing the right care at the right time. This study examined whether socio-economic status (SES) and rural versus urban living location are associated with the time between diagnosis and care home admission in PwD living in Wales, UK.

METHODS/DESIGN

This study linked routine health data and an e-cohort of PwD who have been admitted into a care home between 2000 and 2018 living in Wales. Survival analysis explored the effects of SES, living location, living situation, and frailty on the time between diagnosis and care home admission.

RESULTS

In 34,514 PwD, the average time between diagnosis and care home admission was 1.5 (±1.4) years. Cox regression analysis showed that increased age, living alone, frailty, and living in less disadvantaged neighbourhoods were associated with faster rate to care home admission. Living in rural regions predicted a slower rate until care home admission.

CONCLUSIONS

This is one of the first studies to show a link between socio-economic factors on time to care home admission in dementia. Future research needs to address variations in care needs between PwD from different socio-economic and geographical backgrounds.
