Ethical Considerations in Dementia Diagnosis and Care: AAN Position Statement

The Return of Biomarker Results in Research: Balancing Complexity, Precision, and Ethical Responsibility

Recent research aimed at the discovery, integration, and communication of health outcome measures (or "biomarkers") in Alzheimer's disease has raised challenging questions related to whether, how and when results from these investigations should be disclosed to research participants. Reflecting the apparent heterogeneity of many neurodegenerative diseases, biomarker or other risk factor results are often probabilistic, interactive, multi-modal, and selective. Such characteristics make it very complex to summarize and communicate to clinicians, researchers, and research participants. Whereas the format and content of academic literature is well-managed by the peer-review process, reporting individualized results to participants involves complex, sensitive, and ethical considerations. This paper describes three key factors to consider in decisions about the return of results to research participants: complexity, precision, and responsibility. The paper also presents six practical recommendations for implementing meaningful and ethical communication with research participants.

Identifying undergraduate nurses´ learning requirements and teaching strategies in dementia care education: A nominal group technique

AIM

Identify priorities and reach a consensus on student nurses´ learning requirements and the best-suited teaching strategies in dementia care.

BACKGROUND

Dementia has become a global health priority. Nurses are primary service providers for people with dementia, but they may fall short on professional training. Nursing curricula still lacks a clear educational framework for dementia, meaning that nurse educators must make decisions amidst uncertainty.

DESIGN

Nominal group technique based on the conceptual framework proposed by Van de Ven and Delbecq (1972).

METHODS

A structured face-to-face meeting convened in November 2021 involved nine participants who were directly involved in dementia care. The steps in the technique were (a) idea generation, (b) round-robin recording, (c) discussion, (d) voting and ranking, (e) discussion on the vote and (f) re-ranking. Participants answered two nominal questions. Consent, anonymity, feedback and iteration were guaranteed throughout the process.

RESULTS

The nominal group prioritized theoretical understanding of dementia, communication, caregivers´ needs, comprehensive assessment and ethical practice as learning requirements for nursing students. The outstanding teaching strategy discussed included various approaches to experiential learning.

CONCLUSIONS

The nominal group technique process explored learning requirement priorities for student nurses within a specific context. Participants discussed experiential learning as the best-suited teaching strategy. Findings could support nurse educators to design and deliver better dementia education.

Management of REM sleep behavior disorder: an American Academy of Sleep Medicine clinical practice guideline

INTRODUCTION

This guideline establishes clinical practice recommendations for the management of rapid eye movement sleep behavior disorder (RBD) in adults.

METHODS

The American Academy of Sleep Medicine (AASM) commissioned a task force of experts in sleep medicine to develop recommendations and assign strengths based on a systematic review of the literature and an assessment of the evidence using Grading of Recommendations, Assessment, Development and Evaluation methodology. The task force provided a summary of the relevant literature and the certainty of evidence, the balance of benefits and harms, patient values and preferences, and resource use considerations that support the recommendations. The AASM Board of Directors approved the final recommendations.

GOOD PRACTICE STATEMENT

The following good practice statement is based on expert consensus, and its implementation is necessary for the appropriate and effective management of patients with RBD: It is critically important to help patients maintain a safe sleeping environment to prevent potentially injurious nocturnal behaviors. In particular, the removal of bedside weapons, or objects that could inflict injury if thrown or wielded against a bed partner, is of paramount importance. Sharp furniture like nightstands should be moved away or their edges and headboard should be padded. To reduce the risk of injurious falls, a soft carpet, rug, or mat should be placed next to the bed. Patients with severe, uncontrolled RBD should be recommended to sleep separately from their partners, or at the minimum, to place a pillow between themselves and their partners.

RECOMMENDATIONS

The following recommendations, with medications listed in alphabetical order, are a guide for clinicians in choosing a specific treatment for RBD in adults. Each recommendation statement is assigned a strength ("strong" or "conditional"). A "strong" recommendation (ie, "We recommend…") is one that clinicians should follow under most circumstances. A "conditional" recommendation (ie, "We suggest…") is one that requires that the clinician use clinical knowledge and experience and strongly consider the patient's values and preferences to determine the best course of action.

Adult patients with isolated RBD.

1. The AASM suggests that clinicians use clonazepam (vs no treatment) for the treatment of isolated RBD in adults. (CONDITIONAL).

2. * The AASM suggests that clinicians use immediate-release melatonin (vs no treatment) for the treatment of isolated RBD in adults. (CONDITIONAL).

3. * The AASM suggests that clinicians use pramipexole (vs no treatment) for the treatment of isolated RBD in adults. (CONDITIONAL).

4. The AASM suggests that clinicians use transdermal rivastigmine (vs no treatment) for the treatment of isolated RBD in adults with mild cognitive impairment. (CONDITIONAL).

Adult patients with secondary RBD due to medical condition.

5. * The AASM suggests that clinicians use clonazepam (vs no treatment) for the treatment of secondary RBD due to medical condition in adults. (CONDITIONAL).

6. * The AASM suggests that clinicians use immediate-release melatonin (vs no treatment) for the treatment of secondary RBD due to medical condition in adults. (CONDITIONAL).

7. The AASM suggests that clinicians use transdermal rivastigmine (vs no treatment) for the treatment of secondary RBD due to medical condition (Parkinson disease) in adults. (CONDITIONAL).

8. * The AASM suggests that clinicians not use deep brain stimulation (DBS; vs no treatment) for the treatment of secondary RBD due to medical condition in adults. (CONDITIONAL).

Adult patients with drug-induced RBD.

9. * The AASM suggests that clinicians use drug discontinuation (vs drug continuation) for the treatment of drug-induced RBD in adults. (CONDITIONAL).

* The Recommendations section of this paper includes remarks that provide additional context to guide clinicians with implementation of this recommendation.

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.

Postmortem Brain Imaging in Alzheimer's Disease and Related Dementias: The South Texas Alzheimer's Disease Research Center Repository

BACKGROUND

Neuroimaging bears the promise of providing new biomarkers that could refine the diagnosis of dementia. Still, obtaining the pathology data required to validate the relationship between neuroimaging markers and neurological changes is challenging. Existing data repositories are focused on a single pathology, are too small, or do not precisely match neuroimaging and pathology findings.

OBJECTIVE

The new data repository introduced in this work, the South Texas Alzheimer's Disease research center repository, was designed to address these limitations. Our repository covers a broad diversity of dementias, spans a wide age range, and was specifically designed to draw exact correspondences between neuroimaging and pathology data.

METHODS

Using four different MRI sequences, we are reaching a sample size that allows for validating multimodal neuroimaging biomarkers and studying comorbid conditions. Our imaging protocol was designed to capture markers of cerebrovascular disease and related lesions. Quantification of these lesions is currently underway with MRI-guided histopathological examination.

RESULTS

A total of 139 postmortem brains (70 females) with mean age of 77.9 years were collected, with 71 brains fully analyzed. Of these, only 3% showed evidence of AD-only pathology and 76% had high prevalence of multiple pathologies contributing to clinical diagnosis.

CONCLUSION

This repository has a significant (and increasing) sample size consisting of a wide range of neurodegenerative disorders and employs advanced imaging protocols and MRI-guided histopathological analysis to help disentangle the effects of comorbid disorders to refine diagnosis, prognosis and better understand neurodegenerative disorders.

“I Didn’t Sign Up for This”: Perspectives from Persons Living with Dementia and Care Partners on Challenges, Supports, and Opportunities to Add Geriatric Neuropalliative Care to Dementia Specialty Care

Background: In the United States, dementia specialty centers affiliated with centers of excellence for research hold promise as locations to develop innovative, holistic care in care systems otherwise siloed by discipline or payer. Objective: We conducted foundational research to inform development of patient-and family-centered palliative care interventions for dementia specialty centers. Methods: We interviewed persons living with dementia (PLWD), current, and former care partners (CP) recruited from a specialty dementia clinic and purposively selected for variation across disease syndrome and stage. A framework method of thematic analysis included coding, analytic matrices, and pattern mapping. Results: 40 participants included 9 PLWD, 16 current CPs, and 15 former CPs of decedents; 48% impacted by Alzheimer’s disease dementia. While help from family, support groups and adult day centers, paid caregiving, and sensitive clinical care were invaluable to PLWD, CPs, or both, these supports were insufficient to navigate the extensive challenges. Disease-oriented sources of distress included symptoms, functional impairment and falls, uncertainty and loss, and inaccessible care. Social and relational challenges included constrained personal and professional opportunities. The obligation and toll of giving or receiving caregiving were challenging. Clinical care challenges for PLWD and/or CPs included care fragmentation, insufficient guidance to inform planning and need for expert interdisciplinary clinical care at home. Conclusion: Findings highlight the breadth and gravity of gaps, which surpass the disciplinary focus of either behavioral neurology or palliative care alone. Results can inform the development of novel interventions to add principles of geriatrics and neuropalliative care to dementia care.
