Abstract
Recognition of the need for the early diagnosis of dementia has been spurred by the development of treatment options and acceptance of dementia as a major public health issue. 1 Early diagnosis has become even more salient as medications have become available that delay cognitive decline.2-6 A wide range of early interventions have been developed to meet the needs of people with dementia and their carers at the early stages of the illness, including medicinal interventions, for example cholinesterase inhibitors and antidepressants, and psychosocial interventions such as peer support groups, education, and counseling.7-14
Despite differing attitudes to diagnosing dementia at an early point,15,16 it has been argued to be a prerequisite for improvements in dementia care.17,18 Early diagnosis creates an opportunity for both practitioners and service users to collaborate in setting goals for care and support and making key decisions about postdiagnostic support needs and care, taking a more proactive approach to life-changing decisions. 19 Timely diagnosis has been shown to enable people with dementia and their carers to learn about the condition, prepare for its likely progression, plan support, and obtain referrals for support services.2,3,15,20-22 From a medical and practical standpoint, timely recognition of dementia allows health and social care staff to manage workload, plan resources, seek to prevent crises, and subsequently reduce associated costs.3,21,23 In addition, delaying cognitive decline delays admission to long-term care and decreases the cost of health care. 3
Despite recognition in the research literature reporting on evidence highlighting the importance of timely diagnosis of dementia, there have been consistent long-standing reports of barriers to early dementia diagnosis in both urban24,25 and rural health care.26-32 More recently, there have been calls for earlier diagnosis17,33-35 that are now part of government policies and strategies.36-40 Older adults living in many rural areas experience numerous barriers to accessing general health care, including transportation difficulties, limited health care supply, lack of quality health care, social isolation, and financial constraints.26,29-32,41-45 Similarly, health professionals practicing in rural areas face specific disadvantages, including limited access to specialists and availability of appropriate assessment tools enabling provision of a differential diagnosis in dementia. 27 An increasingly aging population is likely to put pressure on general health care provision and also increase the need for specific postdiagnostic dementia services available to individuals living in both urban and rural areas.
A literature review was performed to examine aspects affecting the diagnosis of dementia in remote and rural locations. The following 3 main themes were identified and examined: (1) the role of primary care, (2) barriers to diagnosis and postdiagnostic support in rural and remote areas, (3) and memory clinics.
Method
Five computer databases were searched, including Medline, PsycINFO, PubMed, Cochrane Library, and ScienceDirect. Additional references were identified through hand searches of selected journals and bibliographies of pertinent publications.
A thematic analysis process was used to extract the key themes from the literature.
Search terms included the following: dementia, Alzheimer’s disease, diagnosis, primary care, memory clinic, and barriers. These search terms were matched with “rural” and “remote.” Publications were included in the review if they were published in the English language, across all countries, and between 1999 and 2011.
Results
A total of 66 papers were identified. Of these, 17 papers discussed the diagnosis of dementia in a rural area (Table 1). Additional literature providing information about policy, history, and current dementia initiatives was omitted from the summary table, but is included in the discussion.
An examination of the selected literature identified the following 3 key themes around the provision of dementia services in rural and urban areas: (1) dementia diagnosis in primary care, (2) barriers to diagnosis and/or postdiagnostic support, and (3) memory clinics.

Role of Primary Care
Primary care comprises health care services that are the first point of contact for all patients. Depending on country and locality, diagnostic process may include being seen by a general practitioner (GP), a nurse, or a specialist. Because of their gatekeeping role in most developed countries, general practitioners are central to the provision of health care for the older population and diagnosing dementia.2,17,24,28,46,47,50,53,54,56,59,61,77,78 Following a diagnostic process, appropriate arrangements for postdiagnostic care and support can be made by the primary care team. In light of the demographic trends and rising numbers of dementia diagnoses,78-82 the responsibilities of primary care are likely to become increasingly pronounced.
In rural communities, the most important interventions for people with dementia have been found to consist of consultative support and community-based education. 28 Additionally, an essential skill in the diagnosis and postdiagnostic dementia care provided by the GPs is believed to be an active engagement with patients and their families, for example, careful listening to patients and their families and discussing suspicions with patients and their family.28,46,51,76
The experiences of GPs practicing in rural and/or urban locations are a focus of 17 studies in this review. The literature reveals a number of good practice examples employed by rural GPs to address the reported barriers in accessing specialist services.17,28,45,47,50,51 Rural GPs have been reported to be confident in diagnosing and treating dementia,47,51 appreciative of a specific diagnosis and family input, 28 and to display active involvement in dementia screening. 50 Hansen et al’s 17 study, exploring GPs’ attitudes to dementia diagnosis using a focus group approach, revealed that Australian rural GPs were more likely than their urban counterparts to discuss the diagnosis of dementia and individual cases. On the other hand, rural practitioners have been found to be less likely to consult with a specialist, preferring to deal with a patient autonomously. 4 This reluctance has been justified by limited access to specialist services, availability of community support, and patients’ resistance to medical management in rural Australia. 17 In addition, the same study found urban GPs in Australia to be more positive toward dementia medication, early diagnosis, and specialist referrals.17,45
Specific geriatric training and appropriate support have been proposed to enable both urban and rural GPs to make formal diagnoses and refer patients to appropriate community and social services.47,76 Increasing GPs’ confidence in the management of patients and supporting good practice could lead to an increase in dementia diagnoses and disclosure, as well as better access to appropriate care and support services for persons with dementia and their caregivers living in both urban and rural areas.
Identified research suggests that primary care physicians’ roles are particularly pronounced in rural communities, where access to specialist services is substantially limited and patients rely on the care available to them. 7 Similarly, some needs of dementia care providers tend to be specific to rural and remote settings and include transportation issues, limited access to specialist services, and overcoming negative perceptions of dementia.17,28-31,54,56,57,63,73,83
Barriers to Accessing Diagnostic and/or Postdiagnostic Services in Rural Communities
Availability and accessibility of diagnostic and postdiagnostic services have important implications for the quality of life of people with dementia and their caregivers. Access to diagnostic and postdiagnostic dementia services in rural communities in Scotland, Canada, Tasmania, and Australia has been reported to be significantly limited.17,29,30,31,41-45,54
There are a number of barriers to services characteristic to rural areas, with the most prominent including isolation and distances to specialist services, personal care, care homes, access to carers’ groups, support for the person with dementia, and home modifications, as well as disorientating, distressing, or inappropriate care, and poor relationships with service providers and/or other service users.30,31,41-45,83 Moreover, existing services in rural Scotland and Australia have been reported to be of poor quality and accessibility by service users.29-31,63
Innes et al 29 consider dementia support services from the perspective of service providers working and living within a rural community. Issues reported by service providers include extended hours of practice, professional isolation, recruitment and retention problems, low morale, and limited professional development. Rural nurses were vulnerable to professional isolation compared to urban professionals. An effective support system and improved access to resources would be required to enhance professionals’ satisfaction and efficiency, which would consequently lead to improvement of general quality of services.29,56,73,84
Limited availability of long-distance transportation is a severe barrier to accessing appropriate services and consequently impedes timely diagnosis and provision of appropriate support to people with dementia in studies from rural Tasmania, 41 Australia, 17 Scotland,29-31 and Canada.42,43 However, some difficulties with access to services have been attributed to a lack of awareness about services among carers and health professionals and stigma associated with dementia.
In addition to poor awareness, there was a self-reported lack of knowledge about dementia by health professionals and uncertainty about the role of health care providers reported by carers in Tasmania. Although the need for more information about available services was stressed by all stakeholders, the community mental health nurses were reported to have the central role in the provision of information and coordination of care for persons with dementia and their carers. 41 Health care providers interviewed in the study by Morgan et al 42 argued that the provision of specific information and advice in the early stages of dementia would lead to an increased use of services before crisis situations. Regular contact with the health care and community staff has been argued to prevent crisis situations and enable monitoring of support needs, which would diminish the family caregivers’ burden and impact on the health system. 42
Stigma associated with dementia has been identified as another problem in rural communities. This includes reports of resistance to using services and social withdrawal attributed to the lack of public awareness, negative attitudes about dementia, perceptions of coping, and desire to protect privacy.31,42-45,65,83,85 Despite experiencing high stress levels and concerns about health care, family caregivers have been reported to be reluctant to use existing support services. This is linked to the perceived lack of privacy and concerns about maintaining confidentiality by care home staff. 65 Moreover, utilization of services by family members was often perceived as an acknowledgement of the inability to provide care or as an unnecessary exploitation of resources. Numerous studies have demonstrated that rural families are more likely to perceive caregiving as their duty, and therefore they refrain from using formal services.26,54,85
Despite the numerous identified barriers to accessing dementia services, studies on rural communities have revealed some advantages of living in such populations, namely, a strong cultural identity encouraging a more proactive approach to care and supportive informal network.29-32,41,42 Moreover, individuals with dementia and their carers appreciated services that facilitated socialization and stimulation, suited their needs, provided loving care, and created good relationships with service providers. 32 Informal support received from family and members of the community was of a significant value.29-31 Interestingly, all participants in the study by Innes et al 31 rated the support they received as better than what they would expect to receive in a more urban environment. Participants argued community spirit and informal support as the main reasons for this phenomenon.
Innes et al 31 refer to studies indicating an important distinction between urban and rural models of care with regard to rural health care policy and developing services in rural areas. Despite the recent recognition of dementia-related needs and issues, policy makers seem to neglect issues characteristic to rural and remote areas including the specific needs of persons with dementia, numbers of staff, human resources, skill mix, case loads, geography, access to training, accessibility and range of services, and the distribution of these services. In addition, many authors argue for a need for a more responsive approach to the provision of care in rural communities aimed at controlling costs in some health boards and minimizing differences across dispersed rural communities.31,54,56,57,62,86
The barriers to accessing dementia services in rural communities could potentially be minimized by increasing general public awareness of dementia and the provision of adequate information and advice. An area in need of appropriate intervention is stigma and lack of open communication about issues related to dementia.
Memory Clinics
With initiatives to improve dementia recognition and provision of postdiagnostic support, current services are under pressure to increase the numbers of new referrals from the early intervention stream. 66 One approach to meet this challenge has been the establishment of memory clinics.36,37
Memory clinics are dedicated medical interdisciplinary establishments specializing in the assessment and diagnosis of memory disorders 69 and subsequent monitoring of their treatment. 70 The first memory clinics were set up in the United States in the 1970s and the first clinics in the United Kingdom were established in the 1980s, mainly as academic research centers.67,71 Most UK clinics are based in hospitals, with some providing home care services. 87 Jolley et al 68 argue that clinics should be situated within easy access of the local population and designed according to dementia-friendly guidelines (such as those outlined in the Dementia Services Development Centre Design Audit Tool 88 ). The presence of a memory clinic has been shown to encourage early referrals and to facilitate access to postdiagnostic support. 67
The number of memory clinics, as well as the range of services they provide, has grown considerably in the last decade. 70 According to White, 87 there were approximately 246 memory clinics in the United Kingdom in 2004, but there are no official NHS figures and no specific standards or set models relating to them. In addition, the role of clinics has shifted from academic to service provision with an increasing number of establishments offering old age psychiatry services. According to a survey of 58 British memory clinics by Lindesay et al, 70 the following key functions performed by the clinics were:
specialist assessment or second opinion;
information and advice to patients and caregivers;
treatment initiation and monitoring;
advice on management;
education and training;
screening for drug trials;
screening for other research, and
medico-legal assessments
Referrals to memory clinics are usually made by a range of professionals, with some clinics operating open referral policies.70,71 The most frequent referral sources reported by the memory clinics in the study by Lindesay et al 70 included general practitioners (90%), psychiatrists (86%), geriatricians (78%), other physicians (64%), neurologists (55%), other health professionals (41%), and self-referrals (21%). The involvement of memory clinics in postdiagnostic care and support varies. 68 According to Lindesay et al 70 only 33% of the clinics perform routine follow-up appointments. The remaining clinics followed up only cases with uncertain diagnosis and/or selected groups only. In contrast, the rural Canadian clinic evaluated by Morgan et al 43 offers follow-up assessments at regular intervals (6 weeks, 12 weeks, 6 months, 1 year, and then yearly), using telehealth appointments if required.
A UK example is the Croydon Memory Service Model (CMSM). This service operates according to the following six predefined goals: (1) high acceptability; (2) high appropriate referral rate; (3) successful engagement with people from minority ethnic groups; (4) successful engagement with people with early-onset dementia; (5) focus on engagement with mild cases to enable early identification; and (6) an increase in the overall number of identified dementia cases. This model complements existing health and social care systems by maximizing service efficiency, while providing broadly based care and assessment in people’s own homes. The service is delivered by a multi-agency team that ensures the availability of a range of profession-specific skills. Additionally, all team members, whatever their clinical background, receive appropriate training to complete the initial assessment.22,66,72
Memory clinic services often go beyond the provision of a medical assessment and an accurate diagnosis. Regular follow-up visits, appropriate referrals, and engagement with caregivers and people with dementia can potentially facilitate the progression from a diagnosis to postdiagnostic support. Some clinics maintain an indirect involvement through local communities. Following the diagnosis, patients are directed to appropriate services and agencies available within the locality. 70 In comparison, in remote and rural Scotland where access to memory clinics is limited, the referrals to older adults services are made by community care (80%), primary care (71%), self-referrals (60%), community mental health teams (57%), family members (5%), and hospital consultants (5%). 73
Memory Clinics in a Remote and Rural Context
The model of care offered by memory clinics may be an answer to some of the problems experienced by rural areas where access to specialist services is limited and there is less variability in medical resources. 27 Rural memory clinics can make the diagnostic process more accessible by reducing repeated travel and time to diagnosis.
Morgan et al 43 reported on an evaluation of a one-stop rural memory clinic that aims to provide a comprehensive assessment of dementia and make the process more efficient by reducing repeated travel time and time to diagnosis. The clinic offers a multidisciplinary assessment by a neurologist, neuropsychology team, geriatrician, neuroradiologist, and physical therapist. Following the assessment, an interdisciplinary meeting is held to make appropriate decisions. Following the meeting, patients and family meet the neurologist and neuropsychologist to discuss the diagnosis, receive feedback from the clinical assessments, recommendations for management and care, and referrals to local support services. The key advantage of this rural and remote memory clinic is the provision of a one-stop multiprofessional assessment carried out in one day, which minimizes transport issues and burden on caregivers. It also appears to have the potential to integrate a number of responses to support the social, emotional, and legal needs.
Some of the main challenges faced by the team include integration of service development and evaluation, increasing workload, low referral rates from patients in most rural areas, and limited participation by referring physicians. On the other hand, the clinic has consistently received high satisfaction ratings from patients and carers and continues to facilitate interprofessional practice, research, and training. 43
In the study by Wackerbarth et al, 75 the differences between urban and rural families attending memory clinics is discussed. Similarities were reported in the functional abilities of the participants; however, urban residents were more likely to experience memory problems, personality changes, and behavior problems than rural service users. 75 Despite the differences between urban and rural populations, memory clinics remain an important element of the care pathway in dementia, providing diagnosis and signposting people with dementia to appropriate postdiagnostic support. In addition, the lack of specific guidelines on functionality and structure of memory clinics74,87,89,90 allows for the services to be tailored to the specific needs of the population they serve.
The increasing rates of referrals to memory clinic services and reported high satisfaction levels highlight the importance of developing more accessible and person-centered diagnostic services.43,45,71 Existing evidence shows major variations in practice and standards of service provided by the clinics, and so defining the best practice in memory clinic is problematic. Jolley and Moniz-Cook 69 argue that the future of memory clinics lies in increasing the population coverage by provision of mobile and outreach services, while ensuring that advantage of local support is taken. However, despite the growing interest in the role of memory clinics in provision of dementia diagnosis and subsequent intervention, the evidence on memory clinics running in rural settings is limited.43,45,48
Discussion
Recent developments in dementia services spurred by an increasingly aging population have resulted in a need for improvements in diagnostic processes. Research evidence shows timely diagnosis to be beneficial to different stakeholder groups.2,3,21-23,91 However, successful models and approaches that facilitate timely diagnosis need to be tailored to the needs of service users as well as to environments in which care and support are provided.
Access to an accurate diagnosis is mainly facilitated by primary care staff, including nurses and general practitioners. Although health practitioners have been shown to appreciate the benefits of a timely dementia diagnosis,3,55,59,92,93 numerous studies show reluctance to make and disclose a formal diagnosis.59,93 Evidence shows that changes in dementia practice, including nurse-led diagnosis, education, and uniform diagnostic process, could bring significant improvements to early dementia recognition and effective care management.
Memory clinics have attracted significant attention from researchers and practitioners43,45,71 who present a case for an increasingly important role for this service in dementia care practice. The variability of memory clinics described in the literature suggests that the model is evolving in a way that is more accurately described as memory services. Memory clinics can potentially be adapted to different needs of populations and resources available in particular regions. Memory clinics in rural areas may offer the main point of access to person-centered, accessible diagnostic, and postdiagnostic service that overcome the existing barriers to appropriate care and support for people with dementia and their families.22,36,37,44,45,67,69,71 Until memory service models (including memory clinics) are further developed, it may be that the local doctor will remain as the key access point for those concerned about their memories. In very remote areas it may be impractical to develop a memory service and be more appropriate to ensure local doctors are given high quality, up-to-date information about how to conduct assessments and make a diagnosis of dementia, referring only those with complex presentations on to specialist memory services. Where formal services are lacking, another possible future development would be to develop local self-help groups for people concerned about their memories through the work of national voluntary dementia organizations.
Conclusion
Reviewing literature on the selected diagnostic issues in dementia care practice provides a number of important observations. The studies included in this review suggest that the increasing demand on health and social services for people with dementia and their families has been long recognized as a key driver to service development. The calls for improved diagnostic processes that would encourage timely dementia recognition and referrals to support services have resulted in numerous initiatives aimed to develop appropriate models of care and support.
The key issues identified in this review that need to be overcome to address the needs of people with dementia and their caregivers are insufficient training of health professionals, availability and accessibility of postdiagnostic services, and limited evidence around the use of memory clinics in rural contexts. Access to high quality diagnostic models is required to ensure the reduction of false positive diagnoses that may have a detrimental effect on the well-being and quality of life of individuals and their families. Without a diagnosis, individuals are not given access to medical treatments and health and social care services that may provide support as they adjust to their diagnosis. Of course, if there are few local services available and local stigma then a diagnosis may actually contribute to further anxiety and loss of well-being. Improved public awareness and provision of dementia-specific training for staff could lead to a more efficient utilization of health and social care services achieved, for example, through the identification of a population at risk, making appropriate referrals to memory services, and the provision of pharmacological and therapeutic interventions.
Although existing research provides examples of good practice and successful interventions, there is a need to integrate the efforts and strengthen the evidence for making improvements to dementia care practice.
Distinctions between urban and rural models need to be further examined to ensure a successful delivery of dementia care and support to rural populations experiencing memory problems. Government policy and strategy suggest that change is planned; however, it remains to be seen how effective the implementation of ideals will be for those with dementia living in remote and rural areas and for those providing care services.
