Pathways to diagnosis: exploring the experiences of problem recognition and obtaining a dementia diagnosis among Anglo-Canadians

Facilitators and barriers of help-seeking for persons with dementia in Asia-findings from a qualitative study of informal caregivers

Background and aim

The deterioration in cognition of persons with dementia (PWD) makes their caregivers key players in their help-seeking process. This study aimed to identify the facilitators and barriers of help-seeking for persons with dementia in Asia from the perspective of their informal caregivers.

Methods

A qualitative methodology was adopted in the current study. Twenty-nine informal caregivers of PWD in Singapore were interviewed between April 2019 and December 2020. All interviews were audio-recorded and transcribed verbatim for the analysis.

Results

The transcripts were analyzed using inductive thematic analysis. The results revealed four major themes with 12 sub-themes, including (1) Barriers to diagnosis-seeking (i.e., lack of knowledge and awareness of dementia, emotional denial, resistance from PWD, and delays in the healthcare system); (2) Facilitators of diagnosis-seeking (i.e., synergy between awareness of dementia and an active diagnosis-seeking intention and incidental diagnosis resulting from seeking treatment for comorbid conditions); (3) Barriers to treatment-seeking (i.e., challenges from PWD and disease, challenges faced by caregivers when seeking treatment for PWD, and challenges imposed by the COVID-19 pandemic); (4) Facilitators of treatment-seeking (i.e., caregivers' capabilities of handling PWD, cooperation/compliance from PWD, and an integrated care plan for PWD).

Conclusion

The findings highlight the importance of raising public awareness, enabling health professionals to tailor psychosocial interventions better, and improving community support through dementia awareness and education.

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.

Virtual Assessment as a Way to Reduce Help-seeking Barriers in Older Adults With Subjective Cognitive Decline

Subjective cognitive decline (SCD), a potential early marker for neurodegenerative disease such as Alzheimer's disease, is common among older adults. Although it is often regarded as a personal health concern, most individuals with SCD do not seek help from a health care professional. Help-seeking (HS) is a complex, individualized process with significant life-course implications, and older adults often face several barriers to HS across personal, socioeconomic, and cultural domains. The pandemic exacerbated these barriers by imposing additional limitations on in-person care. In response, virtual assessment became a popular method to conduct remote care. We provide a narrative review of the challenges and triumphs that came with the transition from in-person, pen-paper cognitive assessments to virtual cognitive assessments. In addition, we address the impact virtual assessment had in tackling barriers that previously limited individuals with SCD from formal HS. We argue that virtual cognitive assessment helps alleviate health access barriers to HS (e.g., cost, transportation, and physician availability) and allows individuals with different coping styles to undergo assessment within more convenient environments. We hope the findings presented in this review inform health care practice, public education, and future research targeted towards the use of virtual assessment to facilitate HS in older adults with SCD.

Barriers and Best Practices in Disclosing a Dementia Diagnosis: A Clinician Interview Study

The vast majority of individuals with dementia want to receive a diagnosis. Research suggests, however, that only a fraction of individuals with dementia receive a diagnosis and patients and families often feel the information is poorly explained. We thus aimed to assess clinician-reported barriers to dementia disclosure and recommendations for giving a dementia diagnosis. To accomplish this, we performed telephone interviews with 15 clinicians from different specialties using a semi-structured interview guide. Transcripts were analyzed thematically. Clinician-reported barriers fit 3 categories: patient and caregiver-related barriers, clinician-related barriers, and barriers related to the triadic interaction. Patient and caregiver-related barriers included lack of social support, misunderstanding the diagnosis, and denial. Clinician barriers included difficulty giving bad news, difficulty communicating uncertainty, and lack of time. Triadic interaction barriers included challenges meeting multiple goals or needs and family requests for non-disclosure. Recommendations for best practice included for clinicians to foster relationships, educate patients and family, and take a family-centered approach. Clinicians described recommendations for fostering relationships such as using empathic communication and developing and maintaining connection. Educating patients and families included tailoring communication, explaining how the diagnosis was reached, and following up. Family approaches included meeting with family members prior to delivering the diagnosis and involving the caregiver in the discussion. Findings may inform updated recommendations for best practices when communicating a dementia diagnosis.

Trajectories to a cancer diagnosis: Why and when women seek help for breast symptoms in Vietnam

Women in low- and middle-income countries where the prevalence and mortality of breast cancer are growing rapidly are more likely to be diagnosed at advanced stages, which negatively affects their treatment outcomes and chance of survival. The current literature in those settings tends to focus largely on explaining patient delay in seeking medical attention for breast symptoms. Meanwhile, little is known as to what prompts women to attend screening and diagnostic services after discovering symptomatic breasts. Drawn upon the data from in-depth interviews with 33 breast cancer patients in Central Vietnam conducted in 2019, this paper examines the context of women's decisions about breast screening and how the practice of seeking cancer diagnosis occurred. Our findings reveal an absence of a national screening program and that seeking medical advice was conducted on an ad hoc basis after self-detection of breast symptoms. Women's interpretations of symptomatic breasts as suspicious signs of cancer, the co-occurrence of important life events, or encouragement by people in their social network motivated women to seek medical attention at different public and private health facilities. Their encounters with the health sector often involved multiple visits across time and space in which they experienced various forms of diagnosis delay produced by the health system. Our study carries implications for interventions to encourage women's awareness of early cancer symptoms and prompt medical presentation after self-discovery of symptomatic breasts.

A new model for general practice-led, regional, community-based, memory clinics

Background

Dementia is a major international health issue with high impact on the patient, relatives, and broader society. Routine screening for dementia is limited, despite known benefit of early detection and intervention on quality of care and patient outcomes. Screening is particularly limited in rural and regional areas, despite high burden and projected growth of dementia in these populations. The current study aimed to implement a new general practitioner (GP) led, multidisciplinary, model of care providing dementia detection and referral pathway to a community-based specialist clinic across six regional general practices.

Methods

Cross-sectional analysis of dementia screening and referral characteristics in the St Anthony Family Medical Practices group based in the regional area of Loddon-Mallee, Victoria. Data were collected on demographics and relevant medical history. Cognitive state was assessed using the Mini-Mental State Examination (MMSE), GP Assessment of Cognition (GPCog), and Geriatric Depression Scale (GDS). Referrals and referral outcomes were recorded for geriatrician, psycho-geriatrician, or both.

Results

Eight hundred and eighteenth patients over 65 years were screened, accounting for approximately 24.2% of 65 and over presentations for the practice network. Of those screened, 68.9% were indicated for referral and 30.3% of these were successfully referred. Of the indicated patients who received referrals, 34.2% declined. Many who declined referral had intermediate scores on the cognitive assessments utilized.

Conclusion

Standardised models of care, integrated within community services, are necessary to improve access to early detection, referral and quality management of dementia. The St Anthony Memory Service model will be invaluable in informing future service development, and in particular the development of services for people living with dementia in rural and regional communities.

Examine Race/Ethnicity Disparities in Perception, Intention, and Screening of Dementia in a Community Setting: Scoping Review

Background: Delayed detection and diagnosis of Alzheimer’s Disease and related dementia (ADRD) can lead to suboptimal care and socioeconomic burdens on individuals, families, and communities. Our objective is to investigate dementia screening behavior focusing on minority older populations and assess whether there are ethnic differences in ADRD screening behavior. Methods: The scoping review method was utilized to examine ADRD screening behavior and contributing factors for missed and delayed screening/diagnosis focusing on race/ethnicity. Results: 2288 papers were identified, of which 21 met the inclusion criteria. We identified six dimensions of ADRD screening behavior: Noticing Symptoms, Recognizing a problem, Accepting Screen, Intending Screen, Action, and Integrating with time. Final findings were organized into study race/ethnicity, theoretical background, the methods of quantitative and qualitative studies, description and measures of ADRD screening behavior, and racial/ethnic differences in ADRD screening behavior. Conclusions: A trend in ethnic disparities in screening for ADRD was observed. Our findings point to the fact that there is a scarcity of studies focusing on describing ethnic-specific ADRD screening behavior as well as a lack of those examining the impact of ethnicity on ADRD screening behavior, especially studies where Asian Americans are almost invisible.

Medical help-seeking intentions for cognitive impairment by the patient

Objectives: Older adults represent one of the fastest growing population groups. As the aged population increases, incidence of Alzheimer's disease (AD) and other dementias will also increase. Professionals agree that early intervention is essential for therapeutic and quality of life purposes; however, many older adults wait several months or years to seek medical help after first noticing signs of cognitive impairment. The present study sought to identify the predictors of help-seeking for cognitive impairment by an individual for him/herself after the first detection of symptoms.Method: An online survey was administered to adults (N = 250) 50 years old and older. Individuals responded about their help-seeking intentions in response to a hypothetical vignette depicting symptoms of cognitive decline derived from a similar study with caregivers conducted by Qualls and colleagues. Additional standardized measures measuring constructs such as knowledge of Alzheimer's disease were completed.Results: The present study reveals that cognitive (i.e. symptom identification and disease attribution) and affective (i.e. symptom impact and threat appraisal) factors, as well as an interaction between the two, are predictive of help-seeking intentions with excellent model fit.Conclusion: Help-seeking intentions by individuals with possible cognitive impairment are comparable to those of potential caregivers. Contrary to hypotheses, high threat appraisal positively predicted help-seeking intentions despite the expectation that threat-induced fear would lead to avoidance. Recommendations are made for future research to further investigate both patients' help-seeking intentions and actions in response to signs of cognitive impairment.Supplemental data for this article is available online at https://doi.org/10.1080/13607863.2021.1910791 .

Antipsychotic Medication Risk of Dementia and Death: A Propensity Matched Cohort Study

OBJECTIVE

This study aimed to compare the incidence of dementia and all-cause mortality up to 20 years post-treatment in an index non-demented cohort between antipsychotic (AP) medication treatment and non-AP treatment groups.

METHOD

All patients in Kaiser Permanente Northern California with a major psychiatric diagnosis between 01/01/1996 and 12/31/2000, age ≥ 50 years, and without dementia diagnosis were included. The study cohort was divided into a "user group", patients treated with AP for ≥ 365 days (n = 1,829), and a "non-user group", propensity score matched on age, sex, and race (n = 9,145). The association between AP exposure and dementia or mortality during the follow-up period (01/01/2001-12/31/2015) was evaluated using Cox proportional hazard models adjusted for psychiatric diagnosis, comorbidities, and other medications. The user group had a hazard ratio (HR) of 2.2 (CI 1.8-2.7) for dementia and 1.3 (CI 1.2-1.5) for death. The onset of dementia in the user group was significantly higher in patients aged ≤ 65 years (p < 0.001). The user group was sub-grouped into atypical, typical, and both; HR for dementia was 1.7 (CI 1.2-2.4), 2.5 (CI 1.9-3.1), and 1.8 (CI 1.4-2.4), respectively.

RESULT

Dementia and mortality were significantly higher in patients concurrently treated with benzodiazepine (HR 1.3; CI 1.2-1.5 and HR 1.4; CI 1.3-1.5) or tricyclic antidepressants (HR 1.2; CI 1.1-1.4 and HR 1.1; CI 1.0-1.2), respectively.

CONCLUSION

Our preliminary results reveal an association between AP treatment and increased rates of both dementia and mortality. Future research is needed to substantiate our current findings.

Self-Administered Gerocognitive Examination: longitudinal cohort testing for the early detection of dementia conversion

Background

Significant cognitive changes as individuals’ age are not being identified in a timely manner, delaying diagnosis and treatments. Use of brief, multi-domain, self-administered, objective cognitive assessment tools may remove some barriers in assessing and identifying cognitive changes. We compared longitudinal Self-Administered Gerocognitive Examination (SAGE) test scores to non-self-administered Mini-Mental State Examination (MMSE) scores in 5 different diagnostic subgroups.

Methods

A cohort study evaluating annual rates of change was performed on 665 consecutive patients from Ohio State University Memory Disorders Clinic. Patients with at least two visits 6 months apart evaluated with SAGE and MMSE and classified according to standard clinical criteria as subjective cognitive decline (SCD), mild cognitive impairment (MCI), or Alzheimer’s disease (AD) dementia were included. The pattern of change in SAGE scores was compared to MMSE. One way and repeated measures ANOVA and linear regression models were used.

Results

Four hundred twenty-four individuals (40 SCD, 94 MCI non-converters to dementia, 70 MCI converters to dementia (49 to AD dementia and 21 to non-AD dementia), 220 AD dementia) met inclusion criteria. SAGE and MMSE scores declined respectively at annual rates of 1.91 points/year (p < 0.0001) and 1.68 points/year (p < 0.0001) for MCI converters to AD dementia, and 1.82 points/year (p < 0.0001) and 2.38 points/year (p < 0.0001) for AD dementia subjects. SAGE and MMSE scores remained stable for SCD and MCI non-converters. Statistically significant decline from baseline scores in SAGE occurred at least 6 months earlier than MMSE for MCI converters to AD dementia (14.4 vs. 20.4 months), MCI converters to non-AD dementia (14.4 vs. 32.9 months), and AD dementia individuals (8.3 vs. 14.4 months).

Conclusions

SAGE detects MCI conversion to dementia at least 6 months sooner than MMSE. Being self-administered, SAGE also addresses a critical need of removing some barriers in performing cognitive assessments. Limitations of our single-site cohort study include potential referral and sampling biases. Repetitively administering SAGE and identifying stability or decline may provide clinicians with an objective cognitive biomarker impacting evaluation and management choices.

Understanding help-seeking decisions in people with subjective cognitive decline: A systematic review of qualitative studies

OBJECTIVE

To synthesize the findings of qualitative research on help-seeking in people with subjective cognitive decline.

METHODS

Relevant qualitative studies were identified by searching the PubMed, CINAHL, Ovid Medline, PsycInfo, Embase, and Web of Science databases. Studies that investigated help-seeking behavior in older adults with subjective cognitive decline were retrieved. The systematic review was conducted in line with JBI methodology for systematic reviews of qualitative evidence.

RESULTS

11 studies were included and three themes related to the process of help-seeking for cognitive problems emerged. These themes included: detected changes, challenges in identifying the need for help and decision to seek professional help.

CONCLUSION

Making decisions to seek help for people with subjective cognitive decline is a multi-stage process. A better understanding of the complex psychological responses to subjective cognitive decline among older adults may help health care professionals to develop strategies to improve help-seeking in clinical practice.

Perceived Help-Seeking Difficulty, Barriers, Delay, and Burden in Carers of People with Suspected Dementia

Because of an often complicated and difficult-to-access care system, help-seeking for people with suspected dementia can be stressful. Difficulty in help-seeking may contribute to carer burden, in addition to other known stressors in dementia care. This study examined the relationship between perceived help-seeking difficulty and carer burden, and the barriers contributing to perceived difficulty. We interviewed 110 carers accessing a community-based dementia assessment service for suspected dementia of a family member for their perceived difficulty, delays, and barriers in help-seeking, and carers burden in terms of role strain, self-criticism, and negative emotions. Linear regression models showed that perceived help-seeking difficulty is associated with carer self-criticism, while carer role strain and negative emotions are associated with symptom severity of the person with dementia but not help-seeking difficulty. Inadequate knowledge about symptoms, service accessibility, and affordability together explained more than half of the variance in perceived help-seeking difficulty (Nagelkerke R² = 0.56). Public awareness about symptoms, support in navigating service, and financial support may reduce perceived difficulty in help-seeking, which in turn may reduce carer self-criticism during the early course of illness.

Persistent barriers and facilitators to seeking help for a dementia diagnosis: a systematic review of 30 years of the perspectives of carers and people with dementia

OBJECTIVE

To identify barriers and facilitators to help seeking for a dementia diagnosis from the perspective of carers and people with dementia.

DESIGN

A systematic review of the literature was conducted according to the PRISMA guidelines (PROSPERO protocol registration CRD42018092524). Nine electronic databases were searched for qualitative, quantitative, and mixed methods primary research studies. Two independent reviewers screened titles and abstracts, full texts of eligible studies, and conducted quality appraisal of included articles. A convergent qualitative synthesis approach was used.

RESULTS

From 7496 articles, 35 papers representing 32 studies from 1986 to 2017 were included. Studies originated from 13 countries across 4 continents. Barriers and facilitators were reported predominantly by carers. A small number of studies included people with dementia. Barriers included denial, stigma and fear, lack of knowledge, normalization of symptoms, preserving autonomy, lack of perceived need, unaware of changes, lack of informal network support, carer difficulties, and problems accessing help. Facilitators included recognition of symptoms as a problem, prior knowledge and contacts, and support from informal network.

CONCLUSIONS

Studies from a 30-year period demonstrated that barriers to help seeking persist globally, despite increasing numbers of national dementia policies. Barriers and facilitators rarely existed independently demonstrating the complexity of help seeking for a diagnosis of dementia. Multiple barriers compounded the decision-making process and more than one facilitator was often required to overcome them. Multi-faceted interventions to reduce barriers are needed, one approach would be a focus on the development of dementia friendly communities to reduce stigma and empower people with dementia and carers.

The Lost Years: Delay Between the Onset of Cognitive Symptoms and Clinical Assessment at a Memory Clinic

Background

Early assessment of cognitive symptoms is an issue in geriatrics. This study investigated the delay from the onset of cognitive symptoms to initial clinical assessment and its associations with patients’ sociodemographic and clinical characteristics.

Methods

This is a cross-sectional retrospective study using medical chart review of 316 patients referred for assessment to a university-affiliated memory clinic. Symptom duration was self-reported by patients/carers. Severity of symptoms assessed by the MoCA and FAST instruments was compared according to delay duration (≥3 years vs. <3 years) using chi-squared tests. Logistic regression was used to determine the association between patients’ characteristics and long symptom duration (≥3 years).

Results

At the initial assessment, 29.4% of patients reported experiencing cognitive symptoms for ≥3 years. They were more likely to have MoCA scores ≤17 (47.8 vs. 34.1%; p=.023) and FAST scores ≥5 (21.5 vs. 10.8%; p=.012). They were also significantly older than 75 years (75–84 yr: OR=2.22 [95%CI: 1.11–4.41]; ≥85 yr: 4.36 [2.08–9.11]), presented more depressive symptoms (2.37 [1.40–4.02]), and were less likely to live alone (0.55 [0.31–0.96]).

Conclusions

A significant proportion of patients had cognitive symptoms for years when initially assessed, which delayed diagnosis and management. Stigma, depression, and compensatory help from carers may contribute to this delay.

‘How do they want to know?’ Doctors’ perspectives on making and communicating a diagnosis of dementia

Recent drives to facilitate earlier identification of dementia have led to increased memory clinic referrals and diagnoses. This study explored the perspectives of memory clinic doctors on making and delivering diagnoses. Four focus groups were conducted with 13 psychiatrists and two geriatricians in the UK. Transcripts were coded line by line using NVIVO. Thematic analysis identified 39 categories, 18 sub-themes and eight overarching themes. Inter-rater reliability on 31% of the data was 0.89. Increased public awareness of dementia was viewed positively in facilitating access to diagnosis and treatment. Doctors viewed diagnosis as a process and expressed concerns about limited pre-diagnostic counselling and post-diagnostic support. In diagnostic delivery doctors sought to develop a narrative drawing on the patient’s report of symptoms and adjust explanations to patient preferences and awareness. However, tailoring the delivery to the individual patient was challenging when meeting for the first time. These consultations often involved three participants (doctor, patient and relative), who were felt to have differing needs and expectations. Doctors emphasized that delicacy was required in deciding in what could be discussed in front of both parties, however also stressed the importance of explicitly naming ‘dementia’. Efforts were made to balance honesty and hope when discussing prognosis and medication. The work was sometimes emotionally distressing, with limited supervision. Existing communication training was felt to be inadequate for consultations involving triads or people with cognitive impairment. Delivering a dementia diagnosis is a nuanced and challenging task. Negotiating honest descriptions of a life-limiting condition whilst instilling hope is further complicated when cognitive impairment affects comprehension. Misunderstandings at the time of feedback may limit patient opportunities for informed future planning afforded by early diagnosis. Doctors in memory clinics would benefit from evidence based training and supervision to prepare them for these emotionally challenging and complex consultations.

How people come to recognise a problem and seek medical help for a person showing early signs of dementia: A systematic review and meta-ethnography

Evidence suggests that there is usually a long delay between noticing first signs of dementia and seeking medical help. We conducted a systematic review of what people experience and how they make decisions during this time, and used a meta-ethnographic approach to synthesise the findings. Screening and quality assessment resulted in nine studies eligible for inclusion. People with dementia mainly report experiencing memory lapses, while carers focus on more subtle changes in personality. People respond to these changes in one of three ways: 1) they discount them as normal; 2) they reserve judgement as to their cause and significance, or 3) they misattribute them. Pivotal events can finally trigger help seeking. Active reflection and seeking of further evidence may lead to earlier recognition of the possibility of dementia and the need to seek help; it also reduces the risk of a pivotal event. Public education should aim to improve recognition of more subtle signs and to encourage repeated evaluation and reflection.

Dementia assessment services: What are the perceptions of older people?

OBJECTIVE

To determine how older people with dementia and their family caregivers experience dementia assessment services and preferences for future configuration of diagnostic services.

METHODS

Qualitative, semistructured in-depth interviews were conducted with nine individuals with dementia. In seven instances, the caregiver also took part in the interview, and on two occasions, the interview was with the person with dementia only.

RESULTS

An important contact during assessment of dementia was the general practitioner, in particular working in a way or timeframe which provides clarity and comfort to the person with dementia and their family members. A problematic factor in clear diagnosis was when probable dementia was suspected during hospitalisation for another complaint. Participants expressed a wide range of views in terms of preferred settings for diagnostic services.

CONCLUSION

These findings highlight some key considerations, which should be included in future research leading to decisions about the design of dementia client services.

Exploring dementia management attitudes in primary care: a key informant survey to primary care physicians in 25 European countries

BACKGROUND

Strategies for the involvement of primary care in the management of patients with presumed or diagnosed dementia are heterogeneous across Europe. We wanted to explore attitudes of primary care physicians (PCPs) when managing dementia: (i) the most popular cognitive tests, (ii) who had the right to initiate or continue cholinesterase inhibitor or memantine treatment, and (iii) the relationship between the permissiveness of these rules/guidelines and PCP's approach in the dementia investigations and assessment.

METHODS

Key informant survey.

SETTING

Primary care practices across 25 European countries.

SUBJECTS

Four hundred forty-five PCPs responded to a self-administered questionnaire. Two-step cluster analysis was performed using characteristics of the informants and the responses to the survey.

MAIN OUTCOME MEASURES

Two by two contingency tables with odds ratios and 95% confidence intervals were used to assess the association between categorical variables. A multinomial logistic regression model was used to assess the association of multiple variables (age class, gender, and perceived prescription rules) with the PCPs' attitude of "trying to establish a diagnosis of dementia on their own."

RESULTS

Discrepancies between rules/guidelines and attitudes to dementia management was found in many countries. There was a strong association between the authorization to prescribe dementia drugs and pursuing dementia diagnostic work-up (odds ratio, 3.45; 95% CI 2.28-5.23).

CONCLUSIONS

Differing regulations about who does what in dementia management seemed to affect PCP's engagement in dementia investigations and assessment. PCPs who were allowed to prescribe dementia drugs also claimed higher engagement in dementia work-up than PCPs who were not allowed to prescribe.

Negotiating access to a diagnosis of dementia: Implications for policies in health and social care

The ‘Pathways to Diagnosis’ study captured the experience of the prediagnosis period of Alzheimer’s disease and related dementias through indepth interviews with 29 persons with dementia and 34 of their family caregivers across four sites: anglophones in Calgary, francophones in Ottawa, Chinese-Canadians in Greater Vancouver and Indo-Canadians in Toronto. In this cross-site analysis, we use the ‘Candidacy’ framework to comprehensively explore the challenges to securing a diagnosis of dementia in Canada and to develop relevant health and social policy. Candidacy views eligibility for appropriate medical care as a process of joint negotiation between individuals and health services, which can be understood relative to seven dimensions: identification of need, navigation, appearances at services, adjudication by providers, acceptance of/resistance to offers, permeability of services and local conditions. Interviewees experienced challenges relative to each of the seven dimensions and these varied in form and emphasis across the four ethno-linguistic groups.

Neuropsychological Profile and Dementia Symptom Recognition in Help-Seekers in a Community Early-Detection Program in Hong Kong

OBJECTIVES

To examine the neuropsychological and clinical profile of help-seekers in an early-detection community dementia program and to explore any relationship between profiles and time to seek help.

DESIGN

Cross-sectional.

SETTING

Early-detection community dementia program.

PARTICIPANTS

Help-seekers (N = 1,005) with subjective cognitive complaints or complaints from an informant.

MEASUREMENTS

Neurocognitive testing, including the Cantonese Mini-Mental State Examination (MMSE), Clock Drawing Test, Digit Span, and Fuld Object Memory Evaluation and other clinical and functioning assessments, including the Clinical Dementia Rating (CDR), activities of daily living (ADLs), instrumental ADLs (IADLs), and depressive symptoms. Time since the person or an informant reported that they first noticed symptoms.

RESULTS

Eighty-six percent of help-seekers had at least very mild dementia (CDR score ≥0.5). Cognitive performance was moderately impaired (mean MMSE score 18.4 ± 6.1). They required some assistance with IADLs, had very mild ADL impairments, and had few depressive symptoms. Median time to seek assessment was 12 months (interquartile range 7-30 months) according to the person or the informant (an adult child in 75% of the sample). Using the median-split method, time to seek assessment was classified as early (0-12 months) and late (>12 months). Worse cognitive and IADL performance but not ADL performance or depressive symptoms were observed in late than in early help-seekers. Longer time intervals between symptom recognition and early assessment showed a trend of further impairments on all measures except ADLs.

CONCLUSION

A time interval of more than 12 months between symptom recognition and early assessment appears to be associated with worse cognitive function upon presentation.

Delayed help seeking behavior in dementia care: preliminary findings from the Clinical Pathway for Alzheimer's Disease in China (CPAD) study

BACKGROUND

The prevalence and factors associated with delays in help seeking for people with dementia in China are unknown.

METHODS

Within 1,010 consecutively registered participants in the Clinical Pathway for Alzheimer's Disease in China (CPAD) study (NCT01779310), 576 persons with dementia (PWDs) and their informants reported the estimated time from symptom onset to first medical visit seeking diagnosis. Univariate analysis of general linear model was used to examine the potential factors associated with the delayed diagnosis seeking.

RESULTS

The median duration from the first noticeable symptom to the first visit seeking diagnosis or treatment was 1.77 years. Individuals with a positive family history of dementia had longer duration (p = 0.05). Compared with other types of dementia, people with vascular dementia (VaD) were referred for diagnosis earliest, and the sequence for such delays was: VaD < Alzheimer's disease (AD) < frontotemporal dementia (FTD) (p < 0.001). Subtypes of dementia (p < 0.001), family history (p = 0.01), and education level (p = 0.03) were associated with the increased delay in help seeking.

CONCLUSIONS

In China, seeking diagnosis for PWDs is delayed for approximately 2 years, even in well-established memory clinics. Clinical features, family history, and less education may impede help seeking in dementia care.

Florbetapir F18 PET Amyloid Neuroimaging and Characteristics in Patients With Mild and Moderate Alzheimer Dementia

BACKGROUND

Clinical diagnosis of Alzheimer disease (AD) is challenging, with a 70.9%-87.3% sensitivity and 44.3%-70.8% specificity, compared with autopsy diagnosis. Florbetapir F18 positron emission tomography (FBP-PET) estimates beta-amyloid plaque density antemortem.

METHODS

Of 2052 patients (≥55 years old) clinically diagnosed with mild or moderate AD dementia from 2 solanezumab clinical trials, 390 opted to participate in a FBP-PET study addendum. We analyzed baseline prerandomization characteristics.

RESULTS

A total of 22.4% had negative FBP-PET scans, whereas 72.5% of mild and 86.9% of moderate AD patients had positive results. No baseline clinical variable reliably differentiated negative from positive FBP-PET scan groups.

CONCLUSIONS

These data confirm the challenges of correctly diagnosing AD without using biomarkers. FBP-PET can aid AD dementia differential diagnosis by detecting amyloid pathology antemortem, even when the diagnosis of AD is made by expert clinicians.

Diagnostic communication in the memory clinic: a conversation analytic perspective

OBJECTIVES

Whether and how patients should be told their dementia diagnosis, has been an area of much debate. While there is now recognition that early diagnosis is important for dementia care little research has looked at how dementia-related diagnostic information is actually verbally communicated. The limited previous research suggests that the absence of explicit terminology (e.g., use of the term Alzheimer's) is problematic. This paper interrogates this assumption through a conversation analysis of British naturalistic memory clinic interaction.

METHOD

This paper is based on video-recordings of communication within a UK memory clinic. Appointments with 29 patients and accompanying persons were recorded, and the corpus was repeatedly listened to, in conjunction with the transcripts in order to identify the segments of talk where there was an action hearable as diagnostic delivery, that is where the clinician is evaluating the patient's condition.

RESULTS

Using a conversation analytic approach this analysis suggests that diagnostic communication, which is sensitive and responsive to the patient and their carers, is not predicated on the presence or absence of particular lexical choices. There is inherent complexity regarding dementia diagnosis, especially in the 'early stages', which is produced through and reflected in diagnostic talk in clinical encounters.

CONCLUSION

In the context of continuity of dementia care, diagnostic information is communicated in a way that conforms to intersubjective norms of minimizing catastrophic reactions in medical communication, and is sensitive to problems associated with 'insight' in terms of delivery and receipt or non-receipt of diagnosis.

Help-seeking for dementia: a systematic review of the literature

BACKGROUND

Help-seeking (HS) for dementia presents a great challenge, especially because a timely and appropriate HS process might be associated with better outcomes for the person with dementia, their caregivers, and society. A clear understanding of the HS concept and its measurement in the area of dementia might improve the effectiveness of the process.

AIMS

The aims of our systematic review were: (1) to systematically obtain and evaluate the relevant literature on HS and dementia; and (2) to summarize current research findings and draw conclusions for future research and clinical care in this area.

METHOD

A systematic review of the literature on HS and dementia was conducted up till June 2013.

RESULTS

From the 478 retrieved articles, 48 were included in the review. Conceptually, the studies examined professional and nonprofessional sources of help; showed preference for seeking help from close relatives followed by primary health caregivers; and identified inadequate knowledge and stigmatic beliefs as the main barriers to HS. The majority of the studies did not rely on a theoretical framework.

CONCLUSIONS

Although the body of literature in the area of HS and dementia is growing, several conceptual and methodological limitations still have to be resolved to advance knowledge in the area.

Care pathways for dementia: current perspectives

Uncertainty appears to typify the experience of living with dementia. With an uncertain illness trajectory and unpredictable levels of deterioration and stability in symptoms, people with a diagnosis of dementia may live with uncertainty and anxiety and find it hard to make plans or decisions for their future. People with memory problems and caregivers seeking a diagnosis of dementia may also potentially find themselves navigating a labyrinth-like maze of services, practitioners, assessments, and memory tests, with limited understanding of test scores and little information about what support is available. In this context of uncertainty, the apparent clarity and certainty of a “dementia care pathway” may be attractive. However, the term “dementia care pathway” has multiple and overlapping meanings, which can potentially give rise to further confusion if these are ill-defined or a false consensus is presumed. This review distinguishes four meanings: 1) a mechanism for the management and containment of uncertainty and confusion, useful for the professional as well as the person with dementia; 2) a manual for sequencing care activities; 3) a guide to consumers, indicating eligibility for care activities, or a guide to self-management for dementia dyads, indicating the appropriateness of care activities; and 4) a manual for “walking with” the person. Examples of these approaches are presented from UK dementia services with illustrations of existing care pathways and associated time points, specifically focusing on: 1) early symptom identification and first service encounters, 2) assessment process, 3) diagnostic disclosure, 4) postdiagnostic support, and 5) appropriate interventions. We review the evidence around these themes, as well as discuss service pathways and referral routes used by some services in England and internationally. We conclude that the attraction of the term “care pathway” is seductive, but caution is needed in taking shared understandings for granted.

Public health guidance to facilitate timely diagnosis of dementia: ALzheimer's COoperative Valuation in Europe recommendations

OBJECTIVE

ALzheimer's COoperative Valuation in Europe (ALCOVE) was a Joint Action co-financed by the European Commission to produce a set of evidence-based recommendations for policymakers on dementia. This paper reports on timely diagnosis.

METHODS

Evidence was reviewed from scientific, policy and qualitative research. An online questionnaire was completed by experts from 24 European Union countries detailing current practice. An iterative process with people with dementia, family carers and professionals was utilised to develop recommendations.

RESULTS

Advances in the technical aspects of diagnosis have changed what is understood by early diagnosis. Although research into preclinical stages is crucial, diagnosing at these very earliest stages is not recommended as regular practice. On balance, it is suggested that citizens should have access to accurate diagnosis at a time in the disease process when it can be of most benefit to them. The term timely diagnosis is used to reflect this. The diagnosis can help citizens and their families make sense of what is happening and make lifestyle changes and plans for the future. The central principles identified to maximise benefit and to reduce harm associated with diagnosis at an earlier stage included reducing stigma about dementia; respecting the rights of the individual; recognising that how the diagnosis is given will impact on subsequent adjustment and that post diagnostic support are required for the person and their family. Detailed recommendations are provided for timely detection, the diagnostic process, complex diagnoses, response to early cognitive changes and workforce.

CONCLUSIONS

The recommendations can be utilised at a local, national and European level to benchmark progress.

Rural Caregivers for a Family Member With Dementia

Forecasts of increasing prevalence of dementia in rural settings, coupled with reliance on family caregiver support, indicate that a greater understanding of caregiver distress in these contexts is necessary. The purpose of this study was to examine family caregiver burden and severity of distress on the day that a family member was diagnosed with dementia at a memory clinic that serves a rural population. Participants in this retrospective study were 231 primary family caregivers of a rural community-dwelling person with dementia. On the diagnostic day, women reported more burden and severity of distress than men and spouses reported more severity of distress than adult children. A structural equation model was not supported for the entire sample, but was supported for women caregivers only ( n = 161). Caregiver distress related to dementia-specific behaviors explained both global distress and burden. Patients’ functional decline was related to caregiver burden.

From forgetfulness to dementia: clinical and commissioning implications of diagnostic experiences

BACKGROUND

The National Dementia Strategy in England stressed the importance of earlier diagnosis of dementia. In-depth knowledge of the experiences of patients using such services remains an evidence gap.

AIM

To increase understanding of the experiences of people developing dementia and of their carers, to inform practice and decision making.

DESIGN AND SETTING

A retrospective and prospective qualitative interview study of participants recruited from four memory clinics in London, the north-west and the north-east of England.

METHOD

Purposive sampling was used to recruit 27 individuals with memory problems and 26 supporters and carers. Interviews explored referral pathways, assessment processes, disclosure of the diagnosis, experiences of being prescribed medication to help with symptoms, and issues of risk and decision making.

RESULTS

Few participants experienced the process of memory assessment as patient centred. Where assessment processes were lengthy and drawn out, participants experienced considerable uncertainty. Many experienced tests and assessments as distressing, sometimes in settings that were perceived as alarming or potentially stigmatising by association. Information provision and communication were variable and practitioners were not always thought to help people to make sense of their experiences.

CONCLUSION

The transition from the early stages of cognitive impairment is not straightforward. There is potentially much uncertainty and waiting. Primary care practitioners may be better able to provide tailored support to individuals and their carers during this time if they are aware of what patients are anticipating and are informed about the diagnostic 'journey' by the insights of those who have experienced it.

Articulating the strategies for maximising the inclusion of people with dementia in qualitative research studies

It is essential to understand the experience of living with dementia from the perspective of the person with dementia so that services can be appropriately constructed. This review paper, drawing on prior work, identifies key strategies for the meaningful inclusion of persons with dementia within qualitative research studies, it examines the articulation of these strategies and shares how these strategies were operationalised within one national research study in Ireland. Strategies within the literature were categorised and then synthesized into a guide consisting of four main areas; gaining COnsent, maximizing Responses, Telling the story, and Ending on a high (CORTE). The CORTE guideline was used to as a tool for analysing relevant research reports. CORTE is a synthesized account of grouped strategies that could be used to maximize the meaningful involvement of persons with dementia and can also provide a guide for reporting the strategies used so that researchers can learn from each other.

Negotiating a labyrinth: experiences of assessment and diagnostic journey in cognitive impairment and dementia

OBJECTIVES

There has been a global push towards the earlier diagnosis of dementia, but there is little understanding of the transitions along the assessment and diagnostic pathway from the perspective of people affected by memory problems, cognitive impairment and early dementia. This study explores the experience of the assessment and diagnostic pathway for people with cognitive impairment and their family carers.

METHODS

Qualitative interviews with 27 people with cognitive impairment and 26 carers (20 dyads) using four memory services before and after diagnosis disclosure were conducted. Interview transcripts were subject to constant comparative analysis and interpretations subject to discussion at regular 'analysis clinics'.

RESULTS

Twelve sub-themes were identified along four points on the assessment journey. Feelings of confusion, uncertainty and anxiety over interminable waiting times dominated. Participants often felt without support to manage their uncertainties, emotions and did not know where to turn for support. Some were highly critical of the systemic process of assessment and diagnosis disclosure but were generally positive of the practice of individual professionals.

CONCLUSIONS

Service providers should review the process of assessment and diagnosis disclosure for people with cognitive impairment and their carers. They should develop a process that is person centred and accommodates the individualised preferences. The development of service systems to provide continuous relevant information and clarity to service users needs to involve all stakeholders, including people with cognitive impairment and their carers.

Informal caregivers' hopes and expectations of a referral to a memory clinic

Although only 20-50% of individuals with dementia are diagnosed, early diagnosis enables patients and families to access interventions and services, and plan for the future. The current study explored the experiences of rural family caregivers in the period leading up to a diagnostic assessment at a Canadian memory clinic, their hopes and expectations of the assessment, and their experiences in the six months following diagnosis. Using a longitudinal, retrospective and prospective qualitative research design, caregivers of 30 patients referred to the clinic were interviewed during the diagnostic assessment process and again six months after the diagnosis. Most caregivers reported first noticing symptoms two years prior to diagnosis. The pre-diagnostic interviews revealed a prevalent 'need to know' among caregivers that drove the help-seeking process. Caregivers hoped that the diagnosis would have the benefits of 'naming it,' 'accessing treatment,' 'knowing what to expect,' and 'receiving guidance.' When asked six months later about the impact of the diagnosis, the main theme was 'acceptance and moving forward.' Caregivers reported that the diagnosis provided 'relief,' 'validation,' and 'improved access to services.' These findings can inform care practices of primary health care providers who represent the first point of contact regarding expectations and experiences of dementia-related diagnoses.

Health care experiences of people with dementia and their caregivers: a meta-ethnographic analysis of qualitative studies

BACKGROUND

Understanding the health care experience of people with dementia and their caregivers is becoming increasingly important given the growing number of affected individuals. We conducted a systematic review of qualitative studies that examined aspects of the health care experience of people with dementia and their caregivers to better understand ways to improve care for this population.

METHODS

We searched the electronic databases MEDLINE, Embase, PsychINFO and CINAHL to identify relevant articles. We extracted key study characteristics and methods from the included studies. We also extracted direct quotes from the primary studies, along with the interpretations provided by authors of the studies. We used meta-ethnography to synthesize the extracted information into an overall framework. We evaluated the quality of the primary studies using the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist.

RESULTS

In total, 46 studies met our inclusion criteria; these involved 1866 people with dementia and their caregivers. We identified 5 major themes: seeking a diagnosis; accessing supports and services; addressing information needs; disease management; and communication and attitudes of health care providers. We conceptualized the health care experience as progressing through phases of seeking understanding and information, identifying the problem, role transitions following diagnosis and living with change.

INTERPRETATION

The health care experience of people with dementia and their caregivers is a complex and dynamic process, which could be improved for many people. Understanding these experiences provides insight into potential gaps in existing health services. Modifying existing services or implementing new models of care to address these gaps may lead to improved outcomes for people with dementia and their caregivers.

The nurse's role in closing the diagnostic gap for people with dementia

Inequalities in health-care access exist for people with dementia (PWD), as reflected in regional, national and international variations in diagnostic rates. This article considers three overlapping themes that emerged from a literature search on the subject: GP competencies, confidence and belief systems; lack of awareness of dementia and different belief systems among carers; and the context of primary health care. These three themes support policy drivers on perceived barriers to achieving a diagnosis of dementia. The context of primary health care, with GPs often regarded as the first point of contact for PWD and their carers, further inhibits inclusive and equitable access to health care for all. Nurses work at the interface between the community and PWD, and are well placed to identify subtle changes during the early stage of dementia. Due to a rising ageing population, the context of primary care needs to change, utilising nurses' roles within public health and secondary prevention.

Time to diagnosis in young-onset dementia as compared with late-onset dementia

BACKGROUND

The extent to which specific factors influence diagnostic delays in dementia is unclear. Therefore, the aim of the present study was to compare duration from symptom onset to diagnosis for young-onset dementia (YOD) and late-onset dementia (LOD) and to assess the effect of age at onset, type of dementia, gender, living situation, education and family history of dementia on this duration.

METHOD

Data on 235 YOD and 167 LOD patients collected from caregivers from two prospective cohort studies were used. Multiple linear regression analysis was performed.

RESULTS

The duration between symptom onset and the diagnosis of YOD exceeded that of LOD by an average of 1.6 years (2.8 v. 4.4 years). Young age and being diagnosed with frontotemporal dementia were related to increases in the time to diagnosis. Subjects with vascular dementia experienced shorter time to diagnosis.

CONCLUSIONS

There is a need to raise special awareness of YOD to facilitate a timely diagnosis.

Dementia diagnosis and post-diagnostic support in Scottish rural communities: experiences of people with dementia and their families

This paper explores the reported difficulties and satisfactions with diagnostic processes and post-diagnostic support offered to people with dementia and their families living in the largest remote and rural region in Scotland. A consultation with 18 participants, six people with dementia and 12 family members, was held using semi-structured interviews between September and November 2010. Three points in the diagnostic process were explored: events and experiences pre-diagnosis; the experience of the diagnostic process; and post-diagnostic support. Experiences of people with dementia and their carers varied at all three points in the diagnostic process. Participant experiences in this study suggest greater efforts are required to meet Government diagnosis targets and that post-diagnostic support needs to be developed and monitored to ensure that once a diagnosis is given people are well-supported. Without post-diagnostic provision Government targets for diagnosis are just that, quota targets, rather than a means to improve service experiences.

Building better systems of care for Aboriginal and Torres Strait Islander people: findings from the Kanyini health systems assessment

BACKGROUND

Australian federal and jurisdictional governments are implementing ambitious policy initiatives intended to improve health care access and outcomes for Aboriginal and Torres Strait Islander people. In this qualitative study we explored Aboriginal Medical Service (AMS) staff views on factors needed to improve chronic care systems and assessed their relevance to the new policy environment.

METHODS

Two theories informed the study: (1) 'candidacy', which explores "the ways in which people's eligibility for care is jointly negotiated between individuals and health services"; and (2) kanyini or 'holding', a Central Australian philosophy which describes the principle and obligations of nurturing and protecting others. A structured health systems assessment, locally adapted from Chronic Care Model domains, was administered via group interviews with 37 health staff in six AMSs and one government Indigenous-led health service. Data were thematically analysed.

RESULTS

Staff emphasised AMS health care was different to private general practices. Consistent with kanyini, community governance and leadership, community representation among staff, and commitment to community development were important organisational features to retain and nurture both staff and patients. This was undermined, however, by constant fear of government funding for AMSs being withheld. Staff resourcing, information systems and high-level leadership were perceived to be key drivers of health care quality. On-site specialist services, managed by AMS staff, were considered an enabling strategy to increase specialist access. Candidacy theory suggests the above factors influence whether a service is 'tractable' and 'navigable' to its users. Staff also described entrenched patient discrimination in hospitals and the need to expend considerable effort to reinstate care. This suggests that Aboriginal and Torres Strait Islander people are still constructed as 'non-ideal users' and are denied from being 'held' by hospital staff.

CONCLUSIONS

Some new policy initiatives (workforce capacity strengthening, improving chronic care delivery systems and increasing specialist access) have potential to address barriers highlighted in this study. Few of these initiatives, however, capitalise on the unique mechanisms by which AMSs 'hold' their users and enhance their candidacy to health care. Kanyini and candidacy are promising and complementary theories for conceptualising health care access and provide a potential framework for improving systems of care.

Psychosocial factors that shape patient and carer experiences of dementia diagnosis and treatment: a systematic review of qualitative studies

BACKGROUND

Early diagnosis and intervention for people with dementia is increasingly considered a priority, but practitioners are concerned with the effects of earlier diagnosis and interventions on patients and caregivers. This systematic review evaluates the qualitative evidence about how people accommodate and adapt to the diagnosis of dementia and its immediate consequences, to guide practice.

METHODS AND FINDINGS

We systematically reviewed qualitative studies exploring experiences of community-dwelling individuals with dementia, and their carers, around diagnosis and the transition to becoming a person with dementia. We searched PubMed, PsychINFO, Embase, CINAHL, and the British Nursing Index (all searched in May 2010 with no date restrictions; PubMed search updated in February 2012), checked reference lists, and undertook citation searches in PubMed and Google Scholar (ongoing to September 2011). We used thematic synthesis to identify key themes, commonalities, barriers to earlier diagnosis, and support identified as helpful. We identified 126 papers reporting 102 studies including a total of 3,095 participants. Three overarching themes emerged from our analysis: (1) pathways through diagnosis, including its impact on identity, roles, and relationships; (2) resolving conflicts to accommodate a diagnosis, including the acceptability of support, focusing on the present or the future, and the use or avoidance of knowledge; and (3) strategies and support to minimise the impact of dementia. Consistent barriers to diagnosis include stigma, normalisation of symptoms, and lack of knowledge. Studies report a lack of specialist support particularly post-diagnosis.

CONCLUSIONS

There is an extensive body of qualitative literature on the experiences of community-dwelling individuals with dementia on receiving and adapting to a diagnosis of dementia. We present a thematic analysis that could be useful to professionals working with people with dementia. We suggest that research emphasis should shift towards the development and evaluation of interventions, particularly those providing support after diagnosis.
