Strengthening the dementia care triad: identifying knowledge gaps and linking to resources

Educational Attainment and Perceived Need for Future ADL Assistance

The current study examined whether educational attainment was associated with perceived need of assistance with future activities of daily living (ADL) among middle-aged and early older-aged adults in the United States. Data for 54,946 adults aged 40-65 years from the 2011-2014 National Health Interview Survey (NHIS) were analyzed using ordered logistic regression. Adults with more education will on average need less ADL assistance than adults with less education. Paradoxically, this study found that higher levels of formal education were associated with perceiving more need for future ADL assistance. This association was also found to vary between males and females. Building knowledge of long-term care planning into existing public educational structures and providing this knowledge to adults no longer involved in the formal educational system through medical providers may lead to better anticipation of future care needs.

Care Setting Transitions for People With Dementia: Qualitative Perspectives of Current and Former Care Partners

Care partners (CP) of people with dementia (PWD) report that decisions about care setting are aided by the support of healthcare providers. However, providers are often underprepared to offer adequate counseling. This qualitative study aimed to identify what support from providers will assist CPs in making decisions related to care setting throughout the dementia journey. We conducted semi-structured interviews with current CPs of PWD and former CPs of decedents. We utilized the constant comparative method to identify themes regarding preferences around care setting as the PWD progressed from diagnosis to end-of-life. Participants were 31 CPs, including 16 current and 15 former CPs. CPs had a mean age of 67 and were primarily white (n = 23/31), female (n = 21/31), and spouses (n = 24/31). Theme 1: Current CPs discussed overwhelming uncertainty pertaining to care setting, expressing "I don't know when I need to plan on more care," and a desire to understand "what stage we are at." Theme 2: Later in the disease, former CPs wanted guidance from healthcare providers on institutional placement ("I sure would've loved some help finding better places") or support to stay in the home ("a doctor had to come to the house"). CPs want early, specific guidance from healthcare providers related to transitions between home and long-term care. Early in the disease course, counseling geared toward prognosis and expected disease course helps CPs make plans. Later, caregivers want help identifying locations or institutionalization or finding home care resources.

Dementia care practices among community healthcare workers in Vietnam: a qualitative descriptive study

BACKGROUND

Vietnam is one of the most rapidly aging countries in the world and the likelihood that someone may have dementia rises dramatically as the population ages. Although caring for persons living with dementia is important, little is known about the circumstances under which community healthcare professionals in Vietnam provide dementia care. This study aimed to describe the practice of caring for persons with dementia among community healthcare professionals in Vietnam.

METHODS

This qualitative descriptive study was conducted with 23 community healthcare professionals recruited from 10 primary healthcare centers, representing 10 of 24 districts in Ho Chi Minh City, Vietnam. Participants were physicians (n = 11), physician's assistants (n = 8) and community nurses (n = 4). Data were collected through in-depth face-to-face semi-structured interviews. Interview data were audio recorded, transcribed verbatim, and analyzed using content analysis.

RESULTS

The mean age of the 23 participants was 44.6 ± 8.8 years; most were female (n = 16, 69.6%); and the mean time of working in the field of dementia care was 15.9 ± 8.4 years. Analysis of the interview data revealed five categories, which informed how care was provided: 1) Knowledge about dementia and its prevalence among older adults; 2) Identification of dementia in Vietnam; 3) Lack of attention to early diagnosis of dementia and difficulty in providing continuous care; 4) Dependence on family members for prompt and continuous care; and 5) challenges to providing dementia care. Despite having knowledge about dementia, some healthcare professionals incorrectly viewed dementia as an inevitable part of the ageing process. Participants reported that their limited training and practical experience in caring for persons with dementia caused a lack of confidence in dementia care.

CONCLUSIONS

The quality of care provided to persons living with dementia was negatively impacted by the limited training of healthcare personnel. The diagnosis, treatment, and provision of supportive services to persons living with dementia and their families are substantial challenges for the Vietnamese healthcare system. It is crucial to initiate and cultivate dementia care education programs aimed at expanding curricula for physicians, physicians' assistants, and nurses.

Dementia awareness among elderly at risk for developing mild cognitive impairment: a cross sectional study at a university-based primary care clinic

BACKGROUND

The number of people living with dementia in Malaysia is expected to increase with the nation's growing elderly population and increased lifespan. The lack of public awareness of dementia is partly compounded by low personal health literacy, while scarce research on local patient awareness further impacts the execution of optimised healthcare services in Malaysia. Patients with chronic disease have an elevated risk of developing mild cognitive impairment (MCI). This study aimed to assess the level of awareness of basic knowledge on dementia among the elderly, especially those at risk of developing mild cognitive impairment and its associated factors.

METHODS

A total of 207 elderly patients aged 60 years and above with chronic diseases attending a university-based primary care clinic were recruited via a systematic randomised sampling method from the clinic patient attendance registry. Respondents were assessed using self-administered online questionnaires distributed via mobile devices. The questionnaire assessed awareness, i.e. ability to correctly answer a self-reported questionnaire on basic dementia knowledge; (adapted from Northern Ireland Life and Times Survey 2010), risk of MCI; (using Towards Useful Aging (TUA)-WELLNESS screening questionnaire) and help-seeking behaviour. Bivariate analysis was used to determine factors associated with dementia awareness.

RESULTS

The response rate was 77.1%, with the majority of participants were females, Chinese and had secondary school education. 39.1% of participants were categorised as high risk of developing MCI. The majority (92.8%) had low dementia awareness and had never shared their concerns regarding dementia (93.2%) nor had any discussion (87.0%) on cognitive impairment with their physicians. Three factors had an association with total dementia awareness score, i.e., younger age group, higher risk of MCI and presence of cardiovascular diseases have significantly lower awareness score (p < 0.05).

CONCLUSION

Awareness of dementia is low among elderly patients with potentially high risk of developing MCI. Efforts to improve awareness on dementia should focus on primary care doctors engaging with at-risk elderly patients to initiate discussion regarding dementia risk while managing modifiable risk factors i.e. hypertension control, diabetes, dyslipidaemia and obesity.

A qualitative study of unpaid caregivers of persons living with dementia and their interactions with health and community-based services and providers

BACKGROUND AND OBJECTIVES

Unpaid caregivers frequently feel underprepared and without adequate training, support, or access to services and resources to care for persons living with dementia. Health and community-based services and providers are critical to support persons living with dementia and their unpaid caregivers. The objective of this research is to understand how unpaid caregivers of persons living with dementia interact with health and community-based services and providers.

RESEARCH DESIGN AND METHODS

We used a qualitative descriptive approach to analyze data from one-on-one semi-structured interviews with unpaid caregivers of persons living with dementia (N = 25). We used framework analysis to organize themes and sub-themes within the systems approach to healthcare delivery.

FINDINGS

Participants described a need for additional guidance, information, and support from health and community-based services and providers. This need was described by participants at 4 levels: individual, care team, organization, and political and economic environment. Participants were active in proposing potential solutions to challenges at all 4 levels, including improving provider awareness and training in dementia, opportunities to provide resources and referrals upon dementia diagnosis, a central clearinghouse for information and resources for persons living with dementia and caregivers, and opportunities to close service gaps.

DISCUSSION AND IMPLICATIONS

Findings of this study highlight the need for increased involvement of caregivers of persons living with dementia as community stakeholders for improving care and services. Recommendations to promote high quality care and better support unpaid caregivers by developing interventions to address multiple aspects of healthcare delivery are consistent with recent legislation and are important areas of future research.

Caregiver Burden and the Impact of Diagnostic Disclosure of Dementia: Why Primary Care Physicians Have a Moral Responsibility to Disclose

AbstractCurrently, the number of individuals affected by Alzheimer's disease is rapidly increasing, expected to reach 14 million in the United States within 30 years. In spite of this impending crisis, less than 50 percent of primary care physicians disclose the diagnosis of dementia to their patients. This failure negatively impacts not only patients but also caregivers, whom dementia patients require to help them meet their needs and who often serve as important decision makers, either as surrogates or as designated healthcare agents for the patient. If caregivers are not informed about and prepared to deal with the challenges they face, their health, both emotional and physical, is put at risk. We will argue that both patient and caregiver have the right to be informed of the diagnosis, as their interests are intertwined, especially as the disease progresses and the caregiver becomes the primary advocate for the patient. The caregiver of an individual with dementia therefore becomes intimately connected to the patient's autonomy in a way few caregivers of other diseases do. In this article, we will show that a timely and thorough disclosure of the diagnosis is morally obligated by the core principles of medical ethics. As the population ages, primary care physicians must see themselves in a triadic relationship with both the dementia patient and caregiver, recognizing that the interests of both are deeply interdependent.

Quantifying the qualitative: exploring epistemic network analysis as a method to study work system interactions

Studying interactions faces methodological challenges and existing methods, such as configural diagramming, have limitations. This work demonstrates Epistemic Network Analysis (ENA) as an analytical method to construct configural diagrams. We demonstrated ENA as an analytical tool by applying this method to study dementia caregiver work systems. We conducted 20 semi-structured interviews with caregivers to collect caregiving experiences. Guided by the Patient Work System model, we conducted a directed content analysis to identify work system components and used ENA to study interactions between components. By using ENA to create configural diagrams, we identified five frequently occurring interactions, compared work system configurations of caregivers providing care at home and away from home. Although we were underpowered to determine statistically significant differences, we identified visual and qualitative differences. Our results demonstrate the capability of ENA as an analytical method for studying work system interactions through configural diagramming. Practitioner summary: A new methodology, Epistemic Network Analysis (ENA), was presented to better support the study of work system interactions through configural diagramming. ENA was applied to qualitative data to demonstrate the capabilities of this method to construct configural diagrams of the work system. This study successfully demonstrated that ENA can visually represent and describe work system configurations.

Assessment of dementia knowledge and its associated factors among final year medical undergraduates in selected universities across Malaysia

Background

The elderly population in Malaysia are projected to reach almost one third of the total population by 2040. The absence of a National Dementia Strategy (NDS) in preparing the healthcare services for the ageing population is compounded by the lack of assessment of preparedness of future healthcare workers to manage complications related to ageing i.e., dementia. Studies in countries with NDS demonstrated lack of dementia knowledge among medical undergraduates. Hence, this study aimed to assess the knowledge on dementia among final year medical undergraduates in Malaysia and its associated factors, using the Dementia Knowledge Assessment Scale (DKAS).

Methods

This cross-sectional study, employed multistage sampling method to recruit final year medical undergraduates from eleven selected public and private medical institutions across Malaysia. Online self-administered measures were delivered to final year medical undergraduates through representatives of medical students’ society after approval from Deanery and institutional ethics board of participating universities. The measure collected demographic information, previous dementia exposure (i.e., formal or informal) and the 25-item Likert scale DKAS. Bivariate analysis and linear regression were conducted to confirm factors influencing dementia knowledge components.

Results

A total of 464 respondents from 7 universities participated in this study. Overall dementia knowledge among respondents with and without exposure, was low, with average score of 29.60 ± 6.97 and 28.22 ± 6.98, respectively. DKAS subscales analysis revealed respondents scored highest in care consideration subscale (9.49 ± 2.37) and lowest in communication and behaviour subscale (4.38 ± 2.39). However, only causes and characteristic subscale recorded significantly higher knowledge score among respondents with previous exposure (7.88 ± 2.58) (p =0.015). Higher knowledge of dementia was associated with previous formal dementia education (p=0.037) and informal occupational/working experience in caring for dementia patients (p = 0.001). Informal occupational/working experience (B = 4.141, 95% CI 1.748–6.535, p = 0.001) had greater effect than formal education (i.e. lectures/workshops) (B = 1.393, 95% CI 0.086–2.700, p = 0.037) to influence respondents’ knowledge on dementia.

Conclusion

Dementia knowledge among final year medical undergraduates is low. To improve dementia knowledge, Malaysian medical curriculum should be reviewed to incorporate formal education and informal occupational/working experience, as early as in undergraduate training to help prepare future healthcare providers to recognise dementia among ageing Malaysians.

A Systematic Review of the Needs of Dementia Caregivers Across Care Settings

The U.S. population of older adults living with dementia is projected to double by 2060. They rely on over 16 million family and unpaid caregivers to provide for their increasingly complex needs and care transitions. Caregivers frequently feel underprepared and without adequate support or access to resources. This systematic review seeks to identify the needs of family and unpaid caregivers of older adults living with dementia across various care settings in the U.S. A systematic search was conducted to identify articles pertaining to the needs of caregivers of older adults living with dementia. The data extraction tool was developed using aspects from the Care Transitions Framework and the Family Caregiver Alliance. Data were organized based on 3 domains of caregiver needs and the care setting(s) of the older adults living with dementia and their caregivers. A total of 31 articles were eligible for inclusion. The majority met the MMAT screening criteria, but more than half only met 2 or less of the 5 quality criteria. Caregivers’ needs were identified in the care settings of home/community-residing, assisted living, long-term care, skilled nursing, and memory care. Most articles either did not specify a care setting or included more than 1 and did not report the findings separately. Caregivers in each care setting, except memory care, identified needs in all 3 of the following domains: (1) social support—formal and informal, (2) confidence, competence, and strengths in the caregiving role, and (3) values and preferences.

Exploring how caregivers for people living with dementia use strategies to overcome work system constraints

Informal caregivers for persons living with dementia (PLWD) require interventions that incorporate caregiving context. We used the Patient Work System model to characterize caregiving context by identifying work system constraints experienced by caregivers during dementia care events (e.g., managing behavioral symptoms of dementia) and strategies used to overcome constraints. We conducted twenty semi-structured interviews with caregivers. We performed upward abstraction and strategy mapping and identified seven work system constraints and eight strategies used to overcome constraints across three care events. We found that strategies used by caregivers either directly modified a constraint or emphasized other positive work system components to overcome a constraint. For example a caregiver modified their bathroom to support the PLWD in bathing themselves properly and safely. These findings provide an understanding of how real-world context influences how caregivers deliver dementia care and the design and implementation of systems that support dementia caregivers.

Exploring how triads of people living with dementia, carers and health care professionals function in dementia health care: A systematic qualitative review and thematic synthesis

BACKGROUND

Many qualitative studies report the post-diagnostic care experiences of carers and people living with dementia; however, this is not often accompanied by opportunities to hear the corresponding views of their health care professionals and how this triadic relationship functions. The aim of this review was to identify and thematically synthesize the experiences of health care services reported by people living with dementia, their carers and health care professionals.

METHODS

Medline, PsycINFO, Embase and CINAHL were searched from inception to 31 July 2019 for qualitative research including people living with dementia, carers and health care professionals. Data were coded and thematically synthesised using NVivo.

RESULTS

Of 10,045 search results, 29 papers relating to 27 studies were included in the final synthesis, including 261 people living with dementia, 444 carers and 530 health care professionals. Six themes emerged related to the functioning of a dementia care triad: (1) involving the person living with dementia, (2) establishing expectations of care and the roles of the members of the triad, (3) building trust, (4) effective communication, (5) continuity of care and (6) understanding the unique relationship dynamics within each triad.

DISCUSSION

The interactions and complexity of triadic dementia care relationships further our understanding of how to improve dementia care. Awareness of possible diverging attitudes highlights areas of necessary improvement and further research into facilitating engagement, such as when multiple professionals are involved or where there are mismatched expectations of the roles of triad members. In order to operate efficiently as a triad member, professionals should be aware of how pre-existing relations can influence the composition of a triad, encourage the involvement of the person living with dementia, clarify the expectations of all parties, establish trusting relationships and enable communication within the direct triad and beyond.

Experiences of people with memory disorders and their spouse carers on influencing formal care: "They ask my wife questions that they should ask me"

Background

People with memory disorders often need care and help from family carers and health and social care providers. Due to the deterioration of cognitive capacity and language skills, they may be unable to convey their thoughts and care preferences to other people. As a result, their agency may become restricted. We investigated the descriptions provided by people with memory disorders and spousal carers of their influence on care in encounters with formal care providers.

Methods

Qualitative thematic analysis was used to identify, analyze, and report themes that describe encounters with professionals in different social or healthcare environments. In-depth interview data were gathered from 19 spouse carers and 15 persons with memory disorders.

Findings

Three themes out of four describe how people with memory disorders and their spouse carers influence formal care: Acquiescence, negotiating care decisions, and taking control. The fourth theme describes lack of influence. People with memory disorders and their spouse carers have ways to influence care, but spouse carers identified more ways of doing so. Both either accepted and followed the care guidelines by the formal carers or took control of the situation and made their own decisions. Spouse carers also sought to influence care decisions through negotiations with formal carers. When formal carers’ decisions were experienced as inconsistent or the rationale of their actions difficult to follow, the possibilities to influence care were limited.

Conclusions

People with memory disorders and their family carers are often in a disadvantaged position as they lack power over the health and social care decision-making during the illness, which is often guided by structural factors. To support the agency of people with memory disorders and to promote shared decision-making, clarification of the service structure and clearer communication between the different parties involved in care are required.

"I was Confused About How to Take Care of Mom Because this Disease is Different Everyday": Vietnamese American Caregivers' Understanding of Alzheimer's Disease

Family members provide the majority of caregiving to individuals living with Alzheimer's disease (AD) and related dementias. Asian American families are disproportionately impacted by the burden of caregiving due to limited knowledge about the disease in this community. This study explored how Vietnamese American caregivers understand AD and provide care to family members with AD. Twenty caregivers who have provided care to a family member with AD participated in a semi-structured qualitative interview. Data were analyzed using thematic analysis. Several themes were identified in the caregivers' understanding of AD: (a) "Now I know:" the disruptions, shocks and surprises leading up to the initial diagnosis; (b) The frustrations of managing family members' cognitive impairments; (c)"Going with the flow:" challenges in managing personality and behavioral changes; (d) The exhaustion of around-the-clock caregiving; (e)"Taking it day by day" in the face of progressively worsening symptoms. Underlining the participants' descriptions of AD was a shared understanding of the progressively worsening, complex and unpredictable nature of the disease that makes it challenging for family caregivers on a daily basis. Findings provide important implications for healthcare workers' outreach to Vietnamese American families to ease the caregiving experience through culturally-responsive education, thereby enhancing the families' ability to recognize the early symptoms and seek appropriate help.

Information needs and information seeking behaviour of people with dementia and their non-professional caregivers: a scoping review

Background

People with dementia often require full-time caregivers especially in the later stages of their condition. People with dementia and caregivers’ access to reliable information on dementia is essential as it may have an important impact on patient care and quality of life. This study aims to provide an overview of the information needs and information seeking behaviour of people with dementia and their non-professional caregivers.

Methods

We conducted a scoping review of the literature and searched four electronic databases for eligible studies published up to August 2018. Two reviewers independently screened studies and extracted data. Information needs were classified according to emerging themes in the literature, and information seeking behaviour was categorized using Wilson’s model of information behaviour.

Results

Twenty studies with a total of 4140 participants, were included in this review. Reported information needs focused on: (i) disease; (ii) patient care provision; (iii) healthcare services; and (iv) caregiver self-care. The most commonly reported information need was on healthcare service-related information. Characteristics found to influence information needs were the severity of dementia as well as patient and caregiver status. People with dementia and non-professional caregivers mainly displayed active searching, information seeking behaviour and preferred using electronic sources to obtain health information.

Conclusion

Current dementia information sources available in English are extensive in the information they offer, but more emphasis needs to be placed on healthcare service-related information. All studies originated from high income countries and focused on information needs of non-professional caregivers only. The only variables found to be associated to information needs were severity of dementia condition as well as patient/caregiver status. The information needs identified in this review can be used to inform development and design of future dementia resources for people with dementia and their non-professional caregivers.

Features of primary care practice influence emergency care-seeking behaviors by caregivers of persons with dementia: A multiple-perspective qualitative study

BACKGROUND

Persons with dementia use emergency department services at rates greater than other older adults. Despite risks associated with emergency department use, persons with dementia and their caregivers often seek emergency services to address needs and symptoms that could be managed within primary care settings. As emergency departments (EDs) are typically sub-optimal environments for addressing dementia-related health issues, facilitating effective primary care provision is critical to reduce the need for, or decision to seek, emergency services. The aim of this study is to explore how features of primary care practice influence care-seeking decisions by community-dwelling persons with dementia and familial caregivers.

METHODS

Semi-structured qualitative interviews were conducted with 27 key dementia-care stakeholders (10 primary care/geriatrics providers, 5 caregivers, 4 emergency medicine physicians, 5 aging service providers, and 3 community paramedics) from multiple health systems. Transcripts from audio recordings were analyzed using a thematic analysis framework to iteratively code and develop emergent themes. Features of primary care were also synthesized into lists of tangible factors leading to emergency care-seeking and those that help prevent (or decrease the need for) ED use.

FINDINGS

Stakeholders identified eight categories of features of primary care encompassing the clinical environment and provision of care. These collapsed into four major themes: (1) clinic and organizational features-including clinic structure and care team staffing; (2) emphasizing proactive approaches to anticipate needs and avoid acute problems-including establishing goals of care, preparing for the future, developing provider-patient/provider-caregiver relationships, and providing caregiver support, education, and resources to help prevent emergencies; (3) health care provider skills and knowledge of dementia-including training and diagnostic capabilities; and (4) engaging appropriate community services/resources to address evolving needs.

CONCLUSIONS

Features of primary care practice influence decisions to seek emergency department care at the system, organizational/clinic, medical, and interpersonal levels, particularly regarding proactive and reactive approaches to addressing dementia-related needs. Interventions for improving primary care for persons with dementia and their caregivers should consider incorporating features that facilitate proactive family-centered dementia care across the four identified themes, and minimize those leading to caregiver decisions to utilize emergency services.

Factors Influencing Emergency Care by Persons With Dementia: Stakeholder Perceptions and Unmet Needs

BACKGROUND/OBJECTIVES

People with dementia (PwD) frequently use emergency care services. To mitigate the disproportionately high rate of emergency care use by PwD, an understanding of contributing factors driving reliance on emergency care services and identification of feasible alternatives are needed. This study aimed to identify clinician, caregiver, and service providers' views and experiences of unmet needs leading to emergency care use among community-dwelling PwD and alternative ways of addressing these needs.

DESIGN

Qualitative, employing semistructured interviews with clinicians, informal caregivers, and aging service providers.

SETTING

Wisconsin, United States.

PARTICIPANTS

Informal caregivers of PwD (n = 4), emergency medicine physicians (n = 4), primary care physicians (n = 5), geriatric healthcare providers (n = 5), aging service providers (n = 6), and community paramedics (n = 3).

MEASUREMENTS

Demographic characteristics of participants and data from semistructured interviews.

FINDINGS

Four major themes were identified from interviews: (1) system fragmentation influences emergency care use by PwD, (2) informational, decision-making, and social support needs influence emergency care use by PwD, (3) emergency departments (EDs) are not designed to optimally address PwD and caregiver needs, and (4) options to prevent and address emergency care needs of PwD.

CONCLUSION

Participants identified numerous system and individual-level unmet needs and offered many recommendations to prevent or improve ED use by PwD. These novel findings, aggregating the perspectives of multiple dementia-care stakeholder groups, serve as the first step to developing interventions that prevent the need for emergency care or deliver tailored emergency care services to this vulnerable population through new approaches.

Empowering Patients with Alzheimer's Disease To Avoid Unwanted Medical Care: A Look At The Dementia Care Triad

Patients with Alzheimer's disease and other types of dementia with acute medical problems, who have lost capacity and are without advance directives, are at risk of being over treated inhospitals. To deal with this growing demographic and ethical crisis, patients with dementia need to plan for their future medical care while they have capacity to do so. This article will examine the role of each member of the dementia care triad and how to empower the patient to participate in planning future medical care. A case will be made that physicians have the same professional disclosure obligations to dementia patients as they do to all other capable patients with terminal illnesses. Because there is little consensus about what facts should be included in a diagnostic disclosure, this article will offer a proposal to empower newly diagnosed patients with dementia with capacity to plan for their future medical care.

Caring for seniors living with dementia means caring for their caregivers too

To improve the care of seniors living with dementia, current initiatives typically target better identification and treatment of the patient. Our recent survey, however, shows we should also focus more on the needs of the informal caregivers who care for this population in primary care settings. This three-round Delphi survey sought caregivers' views on the most frequent and difficult decisions that seniors with dementia, their informal caregivers, and health care providers face in primary care settings in the province of Quebec. Respondents consisted of 31 health care professionals, informal caregivers, managers, representatives of community-based organizations devoted to these seniors, and clinical researchers involved in the organization of care or services to seniors with dementia. When we asked respondents to rank 27 common but difficult decisions involving benefit/harm trade-offs, 83% ranked the decision to choose an option to reduce the burden of informal caregivers as one of the five most important decisions. Choosing a treatment to manage agitation, aggression or psychotic symptoms followed closely, with 79% of respondents selecting it as one of the five most important decisions. Our results point to the importance of attending to the needs of informal caregivers and improving the management of behavioural and psychological symptoms of dementia.

Toxicological Differences Between NMDA Receptor Antagonists and Cholinesterase Inhibitors

Cholinesterase inhibitors (ChEIs), represented by donepezil, rivastigmine, and galantamine, used to be the only approved class of drugs for the treatment of Alzheimer's disease. After the approval of memantine by the Food and Drug Administration (FDA), N-methyl-d-aspartic acid (NMDA) receptor antagonists have been recognized by authorities and broadly used in the treatment of Alzheimer's disease. Along with complementary mechanisms of action, NMDA antagonists and ChEIs differ not only in therapeutic effects but also in adverse reactions, which is an important consideration in clinical drug use. And the number of patients using NMDA antagonists and ChEIs concomitantly has increased, making the matter more complicated. Here we used the FDA Adverse Event Reporting System for statistical analysis , in order to compare the adverse events of memantine and ChEIs. In general, the clinical evidence confirmed the safety advantages of memantine over ChEIs, reiterating the precautions of clinical drug use and the future direction of antidementia drug development.
