Early dementia diagnosis and the risk of suicide and euthanasia

Older Adults' Perspectives on Voluntary Assisted Death: An In-Depth Qualitative Investigation in Australia

Interest in voluntary assisted death (VAD) has been growing among researchers, policy makers and the public. This study aimed to explore older adults' perspectives on VAD in Australia. Using purposive sampling, 15 adults ≥65 years participated in in-depth semi-structured interviews. Interpretative phenomenological analysis identified four themes: cultural reflections; beliefs and worldviews; health aspects; and fabric of life. Participants expressed a desire to have control over end-of-life options, challenged by religious beliefs. Participants expressed concern that VAD legislation could leave people vulnerable to coercion and saw a need for safeguards. Reasons for and against supporting and utilising VAD were discussed. Physical illness was seen a more compelling reason for VAD than mental ill-health. Finally, connections to life and other were discussed, and being able to do the things one loved were named aspects of what it meant to live a good life. Implications are discussed along with future research directions.

Ethical Considerations for Identifying Individuals in the Prodromal/Early Phase of Parkinson's Disease: A Narrative Review

The ability to identify individuals in the prodromal phase of Parkinson's disease has improved in recent years, raising the question of whether and how those affected should be informed about the risk of future disease. Several studies investigated prognostic counselling for individuals with isolated REM sleep behavior disorder and have shown that most patients want to receive information about prognosis, but autonomy and individual preferences must be respected. However, there are still many unanswered questions about risk disclosure or early diagnosis of PD, including the impact on personal circumstances, cultural preferences and specific challenges associated with different profiles of prodromal symptoms, genetic testing or biomarker assessments. This narrative review aims to summarize the current literature on prognostic counselling and risk disclosure in PD, as well as highlight future perspectives that may emerge with the development of new biomarkers and their anticipated impact on the definition of PD.

What medical conditions lead to a request for euthanasia? A rapid scoping review

Background and Aims

Euthanasia is a controversial issue related to the right to die. Although euthanasia is mostly requested by terminally sick individuals, even in societies where it is legal, it is unclear what medical conditions lead to euthanasia requests. In this scoping review, we aimed to compile medical conditions for which euthanasia has been requested or performed around the world.

Methods

The review was preferred reporting items for systematic reviews and meta-analysis for scoping reviews (PRISMA-ScR) checklist. Retrieved search results were screened and unrelated documents were excluded. Data on reasons for conducting or requesting euthanasia along with the study type, setting, and publication year were extracted from documents. Human development index and euthanasia legality were also extracted. Major medical fields were used to categorize reported reasons. Group discussions were conducted if needed for this categorization. An electronic search was undertaken in MEDLINE through PubMed for published documents covering the years January 2000 to September 2022.

Results

Out of 3323 records, a total of 197 papers were included. The most common medical conditions in euthanasia requests are cancer in a terminal phase (45.4%), Alzheimer's disease and dementia (19.8%), constant unbearable physical or mental suffering (19.8%), treatment-resistant mood disorders (12.2%), and advanced cardiovascular disorders (12.2%).

Conclusion

Reasons for euthanasia are mostly linked to chronic or terminal physical conditions. Psychiatric disorders also lead to a substantial proportion of euthanasia requests. This review can help to identify the features shared by conditions that lead to performing or requesting euthanasia.

"I guess you can interpret it in a number of ways like kind of a milder or the mildest form of dementia?": Multi-stakeholder perceptions of cognitive impairment

INTRODUCTION

Mild cognitive impairment (MCI) has a high prevalence and is a risk factor for dementia. Furthering understanding of MCI has been identified as a public health priority. This research aimed to explore views about the causes of cognitive impairment and identify associations between cognitive impairment, dementia, and normative ageing.

METHOD

Semi-structured qualitative interviews were conducted with 22 participants with different stakeholder perspectives on the area of MCI in England, and analysed thematically.

RESULTS

Our analysis focuses on two main themes: 1) causes of cognitive impairment, and 2) ageing, dementia, and dying. Most participants viewed cognitive impairment as a transitional state between normative ageing and dementia. Participants expressed their fear of cognitive impairment and dementia, and made clear links between cognitive impairment and dying. Participants also showed an awareness of the links between lifestyle factors and cognitive health. However, linkage between lifestyle and cognition was discussed only when explicitly asked, suggesting that this was not especially salient for participants when considering the causes and risk factors for cognitive impairment.

CONCLUSION

The results of this study highlight key areas for future public health initiatives, such as a focus on the multitude of benefits offered by adopting a healthy diet and physical exercise in reducing risk of cognitive impairment.

Risk factors for dementia and self-harm: A linkage study

INTRODUCTION

People living with dementia experience poor mental health and high rates of self-harm. We investigated risk factors for self-harm in people aged > 40 years living with dementia and risk factors for dementia after self-harm.

METHODS

Using linked hospital data from New South Wales, Australia, we defined a dementia cohort (n = 154,811) and a self-harm cohort (n = 28,972). Using survival analyses, we investigated predictors of self-harm for the dementia cohort, and predictors of dementia for the self-harm cohort.

RESULTS

We found self-harm or dementia diagnoses occurred most often within 24 months of a dementia diagnosis or initial self-harm presentation, respectively. Men living with dementia, and people with complex psychiatric profiles, had the greatest risk of self-harm. Men who had self-harmed had the greatest risk of dementia diagnoses.

DISCUSSION

Men and people with complex psychiatric profiles and dementia may particularly benefit from post-diagnosis mental and behavioral support to reduce risk of self-harm.

Understanding the Broader Impact of Stuttering: Suicidal Ideation

PURPOSE

Suicide and suicidal ideation are topics that have a long but limited history in stuttering research. Clinicians and clinical researchers have discussed personal and therapeutic experiences with clients who have attempted suicide, died by suicide, or struggled with suicidal thoughts. This study sought to (a) explore the occurrence of suicidal ideation in a sample of adults who stutter; (b) evaluate the relationship between adverse impact related to stuttering and suicidal ideation; and (c) document respondents' thoughts related to suicide, stuttering, and their intersection.

METHOD

One hundred forty adults who stutter completed the Suicide Behavior Questionnaire-Revised (SBQ-R). Of these, 70 participants completed the Perseverative Thinking Questionnaire (PTQ), and 67 completed the Overall Assessment of the Speaker's Experience of Stuttering (OASES). Participants who indicated at least some tendency for suicidal thoughts on the SBQ-R (n = 95) were then asked a set of follow-up questions to explore their experiences of suicidal ideation related to stuttering.

RESULTS

Quantitative data indicated that the majority of adults who reported experiencing suicidal ideation associated these experiences with stuttering (61.2%, n = 59). Individuals with higher Total Scores on the PTQ and OASES were predicted to experience significantly higher rates of suicidal ideation and, in particular, a higher likelihood of having more frequent suicidal ideation in the past year. Qualitative analyses revealed that suicidal ideation intersects meaningfully with the experience of stuttering.

CONCLUSIONS

Data from this study highlight the importance of considering broader life consequences of stuttering that some adults may experience, including suicidal ideation. By being cognizant that clients may develop such thoughts, speech-language pathologists can play a valuable role in identifying and providing necessary support for at-risk individuals.

Cars, Guns, Aging, and "Giving Up the Keys"

BACKGROUND AND OBJECTIVES

Age-associated changes can impair abilities for safe driving and the use of firearms. We sought to examine multiple perspectives on reducing access to firearms, including similarities and differences compared to reducing driving.

RESEARCH DESIGN AND METHODS

Online focus groups and 1-on-1 interviews were conducted (November 2020 to May 2021) in the United States with: older adults who drove and owned firearms; family members of older adult firearm owners/drivers; professionals in aging-related agencies; and firearm retailers/instructors. Recorded sessions were transcribed, coded, and analyzed following a mixed inductive-deductive thematic analysis process.

RESULTS

Among 104 participants (81 in focus groups, 23 in interviews), 50 (48%) were female, and 92 (88%) White. Key similarities: decisions are emotional and challenging; needs change over time; safety concerns are heightened by new impairments; prior experiences prompt future planning; tension between autonomy and reliance on trusted others; and strategies like reframing may ease transitions and avoid confrontations. Key differences: "retirement" was not an acceptable term for firearms; reducing driving may affect daily independence more, but there are few alternatives for the psychological safety conferred by firearms; and there are specific firearm-related legal concerns but more driving-related regulations, policies, and resources.

DISCUSSION AND IMPLICATIONS

The similarities and differences in the processes and preferences related to reducing driving or firearm access have implications for the development of resources to support planning and action. Such resources for the public and providers might empower older adults and their families to make voluntary, shared decisions, and reduce injuries and deaths.

Biomarkers of aging

Aging biomarkers are a combination of biological parameters to (i) assess age-related changes, (ii) track the physiological aging process, and (iii) predict the transition into a pathological status. Although a broad spectrum of aging biomarkers has been developed, their potential uses and limitations remain poorly characterized. An immediate goal of biomarkers is to help us answer the following three fundamental questions in aging research: How old are we? Why do we get old? And how can we age slower? This review aims to address this need. Here, we summarize our current knowledge of biomarkers developed for cellular, organ, and organismal levels of aging, comprising six pillars: physiological characteristics, medical imaging, histological features, cellular alterations, molecular changes, and secretory factors. To fulfill all these requisites, we propose that aging biomarkers should qualify for being specific, systemic, and clinically relevant.

The sanctity of life: The role of purity in attitudes towards abortion and euthanasia

Although abortion and euthanasia are highly contested issues at the heart of the culture war, the moral foundations underlying ideological differences on these issues are mostly unknown. Given that much of the extant debate is framed around the sanctity of life, we argued that the moral foundation of purity/sanctity-a core moral belief that emphasises adherence to the "natural order"-would mediate the negative relationship between conservatism and support for abortion and euthanasia. As hypothesised, results from a nation-wide random sample of adults in New Zealand (N = 3360) revealed that purity/sanctity mediated the relationship between conservatism and opposition to both policies. These results demonstrate that, rather than being motivated by a desire to reduce harm, conservative opposition to pro-choice and end-of-life decisions is (partly) based on the view that ending a life, even if it is one's own, violates God's natural design and, thus, stains one's spiritual purity.

Association between advance care planning and depressive symptoms among community-dwelling people with dementia: An observational cross-sectional study during the COVID-19 pandemic in Japan

Objectives

Advance care planning (ACP) is an increasing priority for people with dementia during the COVID-19 pandemic. This study evaluated the association between ACP initiation and depressive symptoms among home-dwelling people living with dementia.

Methods

An internet-based questionnaire survey was conducted with Japanese family caregivers of home-dwelling persons with dementia in June 2021. Family caregivers evaluated the level of depressive symptoms in persons with dementia using the Neuropsychiatric Inventory (NPI). Caregivers also rated the quality of life of persons with dementia using the EQ-5D-5L.

Results

A total of 379 family caregivers participated in the survey. Depressive symptoms were reported in 143 persons with dementia (37.7%). A total of 155 persons with dementia (40.9%) had initiated ACP, of which 88 (56.8%) had care professionals involved in ACP conversation. After adjusting for the characteristics of persons with dementia and caregivers, persons with professional involvement showed significantly more severe depressive symptoms compared to those who did not initiate ACP. There was no significant difference in the quality of life of persons with dementia according to ACP initiation.

Conclusions

Many home-dwelling persons with dementia experienced depressive symptoms during the COVID-19 pandemic, especially in cases where care professionals were involved in ACP conversations. Optimal and proactive ACP approaches need to be developed to prevent depressive symptoms in newly diagnosed persons.

Euthanasia in persons with advanced dementia: a dignity-enhancing care approach

In current Western societies, increasing numbers of people express their desire to choose when to die. Allowing people to choose the moment of their death is an ethical issue that should be embedded in sound clinical and legal frameworks. In the case of persons with dementia, it raises further ethical questions such as: Does the person have the capacity to make the choice? Is the person being coerced? Who should be involved in the decision? Is the person's suffering untreatable? The use of Advance Euthanasia Directives (AED) is suggested as a way to deal with end-of-life wishes of persons with dementia. However, in the Netherlands-the only country in which this practice is legal-the experiences of patients, doctors, and relatives have been far from satisfactory.Our paper analyses this complex ethical challenge from a Dignity-Enhancing Care approach, starting from the Dutch experiences with AED as a case. We first consider the lived experiences of the different stakeholders, seeking out a dialogical-interpretative understanding of care. We aim to promote human dignity as a normative standard for end-of-life care practices. Three concrete proposals are then presented in which this approach can be operationalised in order to deal respectfully with the end-of-life choices of persons with dementia.

How Residing in a Long-Term Care Facility Affects Suicidal Risk in Patients With Dementia: A Systematic Review

This study aims to review the current literature regarding the association between suicide risk in patients aged 65 years or over with dementia residing in long-term care facilities (LTCs). We also evaluate the most common methods of suicide and protective versus risk factors of nursing home (NH) life on suicide behavior in patients with dementia.

Following preferred reporting items for systematic reviews and Meta-Analyses (PRISMA) guidelines, we performed a systematic review of the relevant free full-text articles found in PubMed, Pub Psych, Cochrane library, and Science Direct up until April 4, 2022. Medical Subject Heading (MeSH) terms and keywords (nursing home, long-term care facility, suicide, self-injurious behavior, dementia), were used to search for full-text randomized clinical trials (RCTs), cross-sectional, case-control, cohort studies, systematic reviews, and studies published in the English language in the last 12 years, focused on human subjects 65 years and older were selected based on predefined eligibility criteria. The search yielded 57,909 articles, of which 12 studies met our inclusion criteria. The articles were subjected to quality appraisal by two reviewers. We used the Newcastle Ottawa scale (NOS) for quality assessment with a mean score of six for 12 observational studies used in this paper.

Of the included reports, six were cross-sectional, five were cohort, and one was case-control. Four articles carefully examine the relationship between dementia and suicide, and all confirm the hypothesis that staying in LTCs reduces the risk of suicide in patients with dementia. However, the rest of the articles generally determine a higher risk of suicide in demented patients and describe male gender, non-Hispanic white race, younger age, newly diagnosed with dementia within one-year, mild dementia, comorbidities, depression, previous history of suicidal behavior, low social support and unstable family relationship as the risk factors of suicide in this population. In comparison, extended stay in NHs and other kinds of LTCs, severe dementia with impaired insight, older age, comorbid schizophrenia, physical disability with limitation and more difficulty preparing and executing a suicide plan, positive and robust social relationships, access to professional caregivers and high frequency of visits from relatives marked as the protective factors.

Existing research on suicide risk in long-term care facility residents with dementia is limited. However, due to the increase in dementia rates that require people to reside in NHs and on the other hand, considering the multiple risk factors of suicide in the elderly living in such places, the need for a screening system for identifying people at suicide risk and performing preventive therapeutic and behavioral interventions is well felt.

The psychological benefits of neuropsychological assessment feedback as a psycho-educational therapeutic intervention: A randomized-controlled trial with cross-over in multiple sclerosis

ABSTRACTEvidence supporting the direct therapeutic benefits of neuropsychological assessment (NPA) feedback relies mostly upon post-feedback consumer surveys. This randomized-controlled trial with cross-over investigated the benefits of NPA feedback in multiple sclerosis (MS). Seventy-one participants were randomly allocated to NPA with feedback or a "delayed-treatment" control group. The primary hypotheses were that NPA feedback would lead to improved knowledge of cognitive functioning and improved coping. Outcome instruments were administered by a research assistant blinded to group allocation. At 1-week post-NPA feedback there were no significant group-by-time interaction effects, indicating no improvement. But nor was there any significant deterioration in psychological wellbeing, despite most participants receiving "bad news" confirming cognitive impairment. At 1-month follow-up, within-subjects' analyses not only found no evidence of any delayed deterioration, but showed clinically significant improvement (small-medium effects) in perceived everyday cognitive functioning, MS self-efficacy, stress and depression. Despite lack of improvement in the RCT component at 1-week post-NPA feedback, the absence of deterioration at this time, in addition to significant improvements in perceived cognitive functioning, self-efficacy and mood at follow-up, together with high satisfaction ratings, all support NPA feedback as a safe psycho-educational intervention that is followed by improved psychological wellbeing over time.Trial registration: Uniform Trial Number identifier: U1111-1127-1585.Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12612000161820.

Firearm ownership, attitudes, and safe storage practices among a nationally representative sample of older U.S. adults age 50 to 80

Firearms are a leading cause of injury mortality across the lifespan, with elevated risks for older adult populations. To inform prevention efforts, we conducted a probability-based web survey (12/1/2019-12/23/2019) of 2048 older adults (age 50-80) to characterize national estimates of firearm ownership, safety practices, and attitudes about health screening, counseling, and policy initiatives. Among older U.S. adults, 26.7% [95%CI = 24.8%-28.8%] report owning one or more firearms. The primary motivation for ownership was protection (69.5%), with 90.4% highlighting a fear of criminal assault. 39.4% of firearm owners reported regularly storing firearm(s) unloaded and locked, with 24.2% regularly storing at least one loaded and unlocked. While most firearm owners found healthcare screening (69.2% [95%CI: 64.9-73.1]) and safety counseling (63.2% [95%CI = 58.8-67.3]) acceptable, only 3.7% of older adults reported being asked about firearm safety by a healthcare provider in the past year. Among firearm owners, there was support for state-level policy interventions, including allowing family/police to petition courts to restrict access when someone is a danger to self/others (78.9% [95%CI = 75.1-82.3]), comprehensive background checks (85.0% [95%CI = 81.5-87.9]), restricting access/ownership under domestic violence restraining orders (88.1%; 95%CI = 84.9-90.7], and removing firearms from older adults with dementia/confusion (80.6%; 95%CI = 76.8-84.0]. Healthcare and policy-level interventions maintained higher support among non-owners than owners (p's < 0.001). Overall, data highlights opportunities exist for more robust firearm safety prevention efforts among older adults, particularly healthcare-based counseling and state/federal policies that focus on addressing lethal means access among at-risk individuals.

Considerations regarding a diagnosis of Alzheimer's disease before dementia: a systematic review

BACKGROUND

The NIA-AA research framework proposes a purely biological definition of Alzheimer's disease (AD). This implies that AD can be diagnosed based on biomarker abnormalities, irrespective of clinical manifestation. While this brings opportunities, it also raises challenges. We aimed to provide an overview of considerations regarding the disclosure of AD pathology before the onset of dementia.

METHODS

A systematic literature review was conducted and reported according to PRISMA guidelines. We searched PubMed, Embase, APA PsycINFO, and Web of Science Core Collection (on 10 December 2020) for references on conveying AD biomarker results to individuals without dementia. Our query combined variations on the terms Alzheimer's disease, disclosure, or diagnosis, preclinical or prodromal, and biomarkers. Two reviewers independently screened the resulting 6860 titles and abstracts for eligibility and examined 162 full-text records for relevance. We included theoretical articles in English, on communicating amyloid and/or tau results to individuals with mild cognitive impairment, subjective cognitive decline, or normal cognition. MAXQDA-software was used for inductive data analysis.

RESULTS

We included 27 publications. From these, we extracted 26 unique considerations, which we grouped according to their primary relevance to a clinical, personal, or societal context. Clinical considerations included (lack of) validity, utility, and disclosure protocols. Personal considerations covered psychological and behavioral implications, as well as the right to (not) know. Finally, societal considerations comprised the risk of misconception, stigmatization, and discrimination. Overall, views were heterogeneous and often contradictory, with emphasis on harmful effects.

CONCLUSIONS

We found 26 diverse and opposing considerations, related to a clinical, personal, or societal context, which are relevant to diagnosing AD before dementia. The theoretical literature tended to focus on adverse impact and rely on common morality, while the motivation for and implications of biomarker testing are deeply personal. Our findings provide a starting point for clinicians to discuss biomarker-based diagnosis with their patients, which will become even more relevant in light of the conditional approval of a first disease-modifying drug for AD.

Suicide risk in first year after dementia diagnosis in older adults

INTRODUCTION

Receiving a diagnosis of Alzheimer's disease or related dementias (ADRD) can be a pivotal and stressful period. We examined the risk of suicide in the first year after ADRD diagnosis relative to the general geriatric population.

METHODS

We identified a national cohort of Medicare fee-for-service beneficiaries aged ≥ 65 years with newly diagnosed ADRD (n = 2,667,987) linked to the National Death Index.

RESULTS

The suicide rate for the ADRD cohort was 26.42 per 100,000 person-years. The overall standardized mortality ratio (SMR) for suicide was 1.53 (95% confidence interval [CI] = 1.42, 1.65) with the highest risk among adults aged 65 to 74 years (SMR = 3.40, 95% CI = 2.94, 3.86) and the first 90 days after ADRD diagnosis. Rural residence and recent mental health, substance use, or chronic pain conditions were associated with increased suicide risk.

DISCUSSION

Results highlight the importance of suicide risk screening and support at the time of newly diagnosed dementia, particularly for patients aged < 75 years.

Associated factors of suicidal ideation among older persons with dementia living at home in eight European countries

OBJECTIVES

This study aimed to investigate the occurrence of suicidal ideation and associated factors in older persons with dementia living at home in eight European countries, and its association with quality of life. Furthermore, changes in suicidal ideation over time were investigated.

METHODS

This cohort study (n = 1,223) was part of the European "RightTimePlaceCare" project conducted in 2010-2013. Participating countries were Estonia, Finland, France, Germany, the Netherlands, Spain, Sweden and the United Kingdom. Baseline and follow-up data were analysed using bivariate and multivariate logistic regression.

RESULTS

The occurrence of suicidal ideation in the participating countries varied between 6% and 24%. Factors significantly (p < 0.0018) associated with suicidal ideation using bivariate analysis were: nationality, depressive symptoms, delusions, hallucinations, agitation, anxiety, apathy, disinhibition, irritability, night-time behaviour disturbances, anxiolytics and anti-dementia medication. In the multivariate regression analysis, country of origin, moderate stage of the dementia, depressive and delusional symptoms, and anti-dementia medication were significantly associated with suicidal ideation (p < 0.05). Over time, suicidal ideation decreased from severe to mild or became absent in 54% of the persons with dementia.

CONCLUSION

It is essential that professionals identify older persons with dementia and suicidal ideation and depressive and other psychological symptoms in order to give them appropriate treatment and provide relief for their informal caregivers. We emphasize the importance of identifying suicidal ideation, irrespective of depressive symptoms, and specifically of paying attention to persons with moderate dementia. Living with the informal caregiver seems to be associated with staying stable without suicidal ideation.

Attitudes Toward Euthanasia: A Longitudinal Analysis of the Role of Economic, Cultural, and Health-Related Factors

CONTEXT

It is crucial that physicians understand differing attitudes toward euthanasia and which factors to consider when discussing end-of-life decisions with patients and families from diverse backgrounds.

OBJECTIVES

To investigate how attitudes toward euthanasia differ among countries, how they change, and how economic, religious, and health-related factors affect these attitudes.

METHODS

We analyzed attitudes toward euthanasia and economic, religious, and health-related indicators using longitudinal (1981-2018) World Values Survey (WVS) data. They included 62 countries with at least a 15-year, three-wave, time series (total n = 389,243 participants). Each national survey interviewed representative samples of adults (mean = 1405).

RESULTS

In the latest wave, The Netherlands had the most favorable views of euthanasia (10-point scale with 1 = least justifiable: mean = 7.47) and Jordan the least (mean = 1.50). Residents of 23 of 24 high-income countries came to view euthanasia as more justifiable, while residents of 12 of 38 middle- and low-income countries came to view it as less justifiable over time. The higher GDP per-capita at the time of survey, the more euthanasia was accepted (r = 0.703; P< 0.0001); the more important respondents viewed religion as being, the less euthanasia was accepted (r = -0.834; P< 0.0001); the higher life expectancy and the lower infant mortality were, the more euthanasia was accepted (r = 0.669; P< 0.0001/r = -0.716; P< 0.0001).

CONCLUSION

Euthanasia-related attitudes differ widely depending on the cultural context; changes over time varied in both directions; euthanasia-related attitudes were associated with economic, religious and health-related factors. With globalization increasing cultural diversity, these findings can inform physicians' communication about end-of-life decisions with patients and families from diverse backgrounds.

Suicide prevention strategies for older persons-An integrative review of empirical and theoretical papers

AIM

To synthesize suicide prevention strategies for older adults. The review question was Which suicide prevention strategies are useful for older adults?

DESIGN

Integrative review.

DATA SOURCES

Academic Search Premier, CINAHL, Ovid PsycINFO and PubMed were searched for articles published between January 2009 and December 2019.

REVIEW METHODS

An integrative review of quantitative, qualitative and theoretical papers with a qualitative thematic analysis.

RESULTS

Key aspects of the included studies contributed to the formulation of four themes: (1) Recognizing older adults' physical and/or mental health problems and referring them for help and treatment, (2) Designing an educational programme, (3) Communication and dialogue about warning signs and (4) Social support and awareness of causing significant others emotional pain. The findings indicate an urgent need to identify effective suicide prevention strategies for older adults.

Risk of Suicide Attempt in Patients With Recent Diagnosis of Mild Cognitive Impairment or Dementia

IMPORTANCE

Little is known about the association between mild cognitive impairment (MCI) and suicide. Most studies have focused on dementia and suicidal behavior, with inconsistent results.

OBJECTIVES

To examine the association between diagnoses of MCI and dementia and suicide attempt and explore potential psychiatric moderators and to assess whether the association differs based on recency of diagnosis.

DESIGN, SETTING, AND PARTICIPANTS

This nationwide cohort study integrated 5 national databases from the Department of Veterans Affairs (VA) and Centers for Medicare & Medicaid Services and included all VA medical centers in the US. US veterans 50 years or older with MCI diagnoses at baseline (October 1, 2011, to September 30, 2013) or earlier (October 1, 2007, to September 30, 2011) were propensity matched 1:3 with (1) patients with dementia diagnoses and (2) patients without either diagnosis based on demographic characteristics and the Charlson Comorbidity Index. Diagnoses of MCI or dementia were defined as recent if there were no diagnosis codes before baseline. Data were analyzed from March 16, 2020, to January 15, 2021.

MAIN OUTCOMES AND MEASURES

Information on suicide attempts through December 31, 2016, provided by the National Suicide Prevention Applications Network (nonfatal) and Mortality Data Repository (fatal).

RESULTS

The study population of 147 595 participants included 21 085 patients with MCI, 63 255 with dementia, and 63 255 in the propensity-matched comparison group. Participants had a mean (SD) age of 74.7 (10.3) years, 143 353 (97.1%) were men, 4242 (2.9%) were women, and 127 065 (86.1%) were non-Hispanic White. A total of 138 patients with MCI (0.7%) and 400 patients with dementia (0.6%) attempted suicide during follow-up, compared with 253 patients without MCI or dementia (0.4%). Exploratory analyses revealed that no psychiatric comorbidity moderated the association between MCI or dementia and suicide attempt. After adjustment for demographic details and medical and psychiatric comorbidities, risk of suicide attempt was consistently highest for patients with a recent MCI or dementia diagnosis, with adjusted hazard ratios (HRs) of 1.73 (95% CI, 1.34-2.22; P < .001) for recent MCI and 1.44 (95% CI, 1.17-1.77; P = .001) for recent dementia. Risk associated with prior diagnosis was not significant (HR for prior MCI, 1.03 [95% CI, 0.78-1.36; P = .84]; HR for prior dementia, 1.14 [95% CI, 0.95-1.36; P = .15]).

CONCLUSIONS AND RELEVANCE

This study found that older adults with recent MCI or dementia diagnoses were at increased risk of attempting suicide. These findings suggest that involvement of supportive services at the time of or soon after diagnoses of MCI or dementia may help mitigate risk of suicide attempts.

The application of a neuropsychological measure of executive working memory in older adults with memory impairment

The component of working memory that the frontal cortex subserves is frequently characterized as the executive working memory (EWM). This study applied a neuropsychological measure of EWM (NPM-EWM) in older adults with memory impairment to investigate the EWM. Thirty-two older adults from the community were recruited as older healthy controls (OHCs), and 58 older adults from a memory clinic were diagnosed with mild cognitive impairment (MCI) and mild dementia (MD). Significant differences were found among the three groups in the Clinical Dementia Rating (CDR), the Chinese version of Mini-Mental State Examination (MMSE-C), and the Cognitive Abilities Screening Instrument (CASI). The NPM-EWM was applied by using the learning task of the Comprehensive Nonverbal Memory Test Battery, where the 7 scores were divided into two categories: mnemonic capacity and executive error. All OHCs, more than 50% MCI, and less than 25% of MD patients passed the NPM-EWM. The MCI-passed and MD-passed subgroups showed similar mnemonic capacity and executive errors, and both the subgroups had significantly worse performance than the OHC group. The MD-passed subgroup had a higher Hamilton Depression Rating Scale (HDRS) score than did the MD-failed subgroup. The MCI-failed subgroup had a higher Hierarchy of Care Required (HCR) level in instrumental activities of daily living (IADL) than did the MCI-passed subgroup. These findings indicated that applying the NPM-EWM for older adults with memory impairment may offer precise and tailored care to a whole person, especially for the MCI patients with poorer EWM and the MD patients with relatively intact EWM.

Biomarker-Based Risk Prediction of Alzheimer’s Disease Dementia in Mild Cognitive Impairment: Psychosocial, Ethical, and Legal Aspects

Background: Today, a growing number of individuals with mild cognitive impairment (MCI) wish to assess their risk of developing Alzheimer’s disease (AD) dementia. The expectations as well as the effects on quality of life (QoL) in MCI patients and their close others through biomarker-based dementia risk estimation are not well studied. Objective: The PreDADQoL project aims at providing empirical data on effects of such prediction on QoL and at developing an ethical and legal framework of biomarker-based dementia risk estimation in MCI. Methods: In the empirical study, 100 MCI-patients and their close others will be recruited from two sites (Germany and Spain). They receive standardized counselling on cerebrospinal fluid (CSF) biomarker-based prediction of AD dementia and a risk disclosure based on their AD biomarker status. A mixed methods approach will be applied to assess outcomes. Results: The pilot-study yielded a specification of the research topics and newly developed questionnaires for the main assessment. Within this binational quantitative and qualitative study, data on attitudes and expectations toward AD risk prediction, QoL, risk communication, coping strategies, mental health, lifestyle changes, and healthcare resource utilization will be obtained. Together with the normative part of the project, an empirically informed ethical and legal framework for biomarker-based dementia risk estimation will be developed. Conclusion: The empirical research of the PreDADQoL study together with the ethical and legal considerations and implications will help to improve the process of counselling and risk disclosure and thereby positively affect QoL and health of MCI-patients and their close others in the context of biomarker-based dementia risk estimation.

Suicide risk within 1 year of dementia diagnosis in older adults: a nationwide retrospective cohort study

BACKGROUND

Although severe dementia could protect against suicide death by decreasing a person's capacity to implement a suicide plan, patients with early dementia may have better cognition, giving them more sustained insight into their disease and better enabling them to carry out a suicide plan. This study investigated suicide risk in older adults within 1 year of receiving a diagnosis of dementia.

METHODS

This study used National Health Insurance Service Senior Cohort data and included 36 541 older adults with newly diagnosed dementia (a Mini-Mental State Examination score ≤ 26 and a Clinical Dementia Rating score ≥ 1 or a Global Deterioration Scale score ≥ 3), including Alzheimer disease, vascular dementia and other/unspecified dementia, from 2004 to 2012. We selected older adults without dementia through 1:1 propensity-score matching using sex, age, comorbidities and index year, with follow-up throughout 2013. We estimated adjusted hazard ratios (AHRs) of suicide deaths within 1 year after diagnosis using a time-dependent Cox proportional hazards model.

RESULTS

We verified 46 suicide deaths during the first year after a dementia diagnosis. Older adults with dementia had an increased risk of suicide death compared to those without dementia (AHR 2.57; 95% confidence interval [CI] 1.49-4.44). Older adults with Alzheimer disease (AHR 2.50; 95% CI 1.41-4.44) or other/unspecified dementia (AHR 4.32; 95% CI 2.04-9.15) had an increased risk of suicide death compared to those without dementia. Patients with dementia but without other mental disorders (AHR 1.96; 95% CI 1.02-3.77) and patients with dementia and other mental disorders (AHR 3.22; 95% CI 1.78-5.83) had an increased risk of suicide death compared to patients without dementia. Patients with dementia and schizophrenia (AHR 8.73; 95% CI 2.57-29.71), mood disorders (AHR 2.84; 95% CI 1.23-6.53) or anxiety or somatoform disorders (AHR 3.53; 95% CI 1.73-7.21), respectively, had an increased risk of suicide death compared to patients with those conditions but without dementia.

LIMITATIONS

This study examined only elderly patients in South Korea, a population with a substantially higher suicide rate than the global population. Caution must be exercised when generalizing the results to populations with dissimilar backgrounds.

CONCLUSION

Patients with dementia had an increased risk of suicide death within 1 year after diagnosis compared to those without dementia.

Comparison of Suicide Risk by Mental Illness: a Retrospective Review of 14-Year Electronic Medical Records

BACKGROUND

Korea is one of the countries with the highest rate of suicide, while suicidality is known to be closely related to mental illnesses. The study aimed to evaluate the suicide rates in psychiatric patients, to compare it to that of the general population, and to investigate the differences among psychiatric diagnoses and comorbidities.

METHODS

Medical records and mortality statistics of psychiatric patients at Seoul National University Hospital from 2003 to 2017 were reviewed. The standardized mortality ratio (SMR) for suicide was calculated to compare the psychiatric patients with the general population. The diagnosis-specific standardized mortality rate and hazard ratio (HR) were adjusted by age, sex, and psychiatric comorbidity (i.e., personality disorder and/or pain disorder).

RESULTS

A total of 40,692 survivors or non-suicidal deaths and 597 suicidal death were included. The suicide rate among psychiatric patients was 5.13-fold higher than that of the general population. Psychotic disorder had the highest SMR (13.03; 95% confidence interval [CI], 11.23-15.03), followed by bipolar disorder (10.26; 95% CI, 7.97-13.00) and substance-related disorder (6.78; 95% CI, 4.14-10.47). In survival analysis, psychotic disorder had the highest HR (4.16; 95% CI, 2.86-6.05), which was further increased with younger age, male sex, and comorbidity of personality disorder.

CONCLUSION

All psychiatric patients are at a higher risk of suicide compared to the general population, and the risk is highest for those diagnosed with psychotic disorder.

Suicidal and death ideation in patients with progressive supranuclear palsy and corticobasal syndrome

OBJECTIVE

A large proportion of patients with atypical parkinsonian syndromes suffer from depression, an antecedent of suicide. This study aimed to explore the prevalence and clinical correlates of suicidal and death ideation (SDI) in patients with Progressive Supranuclear Palsy (PSP) and Corticobasal Syndrome (CBS), as well as compare the differences with patients with Parkinson's disease (PD).

METHODS

This was a case-control, cross-sectional study. SDI was diagnosed based on the assessment of the Hamilton Depression Rating Scale (HRDS). The prevalence of SDI among patients with PD, PSP, and CBS (n = 3400, 268, and 65 respectively) were compared before and after propensity score matching (PSM). A forward binary logistic regression model was used to explore the associated factors of SDI.

RESULTS

None of the patients reported suicide attempts. The prevalence of SDI in patients with PSP and CBS were 27.2% and 29.2%, respectively, which was significantly higher than that in patients with PD before and after PSM (P < 0.05). The prevalence of SDI was not significantly different among patients with PSP with different subtypes (Richardson syndrome, Parkinsonism, and other), both before and after PSM (P > 0.05). Multivariate analysis indicated that higher gait and midline score and depression were independently associated with an increased risk of SDI in patients with PSP (P < 0.05), while higher non-motor symptoms score and depression were independently associated with the occurrence of SDI in patients with CBS (P < 0.05).

CONCLUSIONS

Our study highlights the importance of screening SDI in patients with PSP and CBS.

The Experience of Adults Bereaved by the Suicide of a Close Elderly Relative: A Qualitative Pilot Study

Suicide in older persons is a serious issue in many countries. The act of intentionally causing one’s own death is often associated with lack of social support, thwarted belongingness, or chronic interpersonal difficulties. Therefore, suicide has a significant interpersonal dimension that can influence those left behind. However, studies that have investigated the impact of older adults’ suicide on their family are scarce. The objective of this pilot study was to assess the feasibility of a qualitative research on the psychosocial experience of adults bereaved by the suicide of an elderly relative. This research could recruit three participants (daughter, grand-son, and grand-niece) who had lost to suicide a close family member aged between 75 and 90. The analysis of the content of the semi-structured interviews revealed seven main themes: (1) finding an explanation to the suicide, (2) give meaning to the loss, (3) the emotional processes of mourning, (4) the repercussions of the suicide on the individual and the family, (5) looking for support, (6) the taboo and secrecy of suicide, and (7) perceptions of aging and the end of life. To explain the suicide of their loved one, the bereaved mentioned various factors related to aging, such as loss of autonomy, illness, and fear of placement. Although the older relative was perceived to be approaching death because of his/her age, the suicide was still unexpected and shocking and led to various emotions (shock, anger, and guilt) and to family conflicts. Suicide remains a taboo subject, but the newly legalized medical assistance in dying is seen as a potential solution to suffering in old age. Further investigation is clearly needed on this topic and this pilot study indicates that the main difficulties will lie in the choice of selection criteria for participants and in the recruitment process.

Multifactorial 10-Year Prior Diagnosis Prediction Model of Dementia

Dementia is a neurodegenerative disorder that affects the older adult population. To date, no cure or treatment to change its course is available. Since changes in the brains of affected individuals could be evidenced as early as 10 years before the onset of symptoms, prognosis research should consider this time frame. This study investigates a broad decision tree multifactorial approach for the prediction of dementia, considering 75 variables regarding demographic, social, lifestyle, medical history, biochemical tests, physical examination, psychological assessment and health instruments. Previous work on dementia prognoses with machine learning did not consider a broad range of factors in a large time frame. The proposed approach investigated predictive factors for dementia and possible prognostic subgroups. This study used data from the ongoing multipurpose Swedish National Study on Aging and Care, consisting of 726 subjects (91 presented dementia diagnosis in 10 years). The proposed approach achieved an AUC of 0.745 and Recall of 0.722 for the 10-year prognosis of dementia. Most of the variables selected by the tree are related to modifiable risk factors; physical strength was important across all ages. Also, there was a lack of variables related to health instruments routinely used for the dementia diagnosis.

Expectations and Concerns of Older Adults With Cognitive Impairment About Their Relationship With Medical Providers: A Call for Therapeutic Alliances

We sought to understand the expectations and concerns of older adults with cognitive impairment with regard to their relationship with medical providers. In particular, we observed whether study participants were involved in therapeutic alliances. Medical providers and patients create therapeutic alliances when they agree on the goals of the treatment and share a personal bond. Whereas such alliances have been studied in cancer research, little is known about therapeutic alliances in dementia research. Data were gathered in a qualitative study of 27 older adults with cognitive impairment and analyzed with narrative analysis. We introduce four case studies that illustrate the effects of having or missing a therapeutic alliance. Whereas the participant in the first case benefited from a therapeutic alliance, the other cases are marked by different experiences of abandonment. Findings suggest that interventions should concentrate on ways to enhance the relationship between medical providers and patients with cognitive impairment.

Suicide and dementia: Systematic review and meta-analysis

INTRODUCTION

To analyse the possible relationship between dementia in the elderly and the subsequent development of suicide ideation, attempts and / or completed suicides.

METHODS

Systematic review and meta-analysis.

SELECTION CRITERIA

studies that analysed the relationship between dementia and suicide.

SEARCH STRATEGY

i) in PubMed, EMBASE, CINAHL, IME and Lilacs until December 2018; ii) manual search of the bibliography of selected articles; iii) contact with leading authors. Article selection and data extraction according to a predefined protocol, including bias risk assessment, were performed by independent peer reviewers. The effect size index was calculated using Odds Ratio (OR) and its 95% confidence interval (random-effects model). Heterogeneity was evaluated with forest plots, Cochran's Q and I² index. Assessment of publication bias using funnel plots ("trim-and-fill" method) and the Egger test. The analysis of moderating variables was performed using a multiple meta-regression under a mixed-effects model.

RESULTS

37 studies and 47 basic units of study were identified. Effect size of the association of dementia with: Suicidal Ideation OR = 1.37 (95% CI: .78-2.39); Suicide Attempt: OR = 2.24 (95% CI: 1.01-4.97); and Completed Suicide: OR = 1.28 (95% CI: .77-2.14). Possible publication bias was ruled out.

CONCLUSIONS

A trend towards suicidal events is identified, especially suicide attempts in people with dementia. Greater attention and care are recommended after a recent diagnosis of dementia, especially with adequate assessment of comorbidities, which could influence the occurrence and outcome of suicidal events.

Assessment of Association between NINJ2 Polymorphisms and Suicide Attempts in an Iranian Population

Suicidal behavior as a psychological problem with high public health burden is associated with a number of genetically determined risk factors. In the current study, we investigated the association between two polymorphisms within the NINJ2 gene and risk of suicide in an Iranian population. The study included 295 individuals who attempted suicide with soft suicide methods, 234 suicide victims and 410 normal controls. The rs11833579 SNP was associated with death from suicide in a codominant model in that the AG genotype decreased the risk of death from suicide compared with the GG genotype (OR (95% CI) = 0.49 (0.34-0.71), adjusted P value = 4e-04). This SNP was also associated with death from suicide in dominant (AG + AA versus GG: OR (95% CI) = 0.63 (0.46-0.87), adjusted P value = 0.011) and overdominant (AG versus GG + AA: OR (95% CI) = 0.49 (0.35-0.69), adjusted P value < 0.0001) models. In addition, this SNP was associated with soft suicide attempts in a codominant model (AG versus AA + GG: OR (95% CI) = 0.7 (0.5-0.98), adjusted P value = 0.02). The rs3806263 SNP was associated with death from suicide in allelic (A versus G: OR (95% CI) = 1.48 (1.17-1.88), adjusted P value = 0.002), codominant (AA versus GG: OR (95% CI) = 3.14 (1.89-5.21), adjusted P value < 0.0001), recessive (AA versus GG + AG: OR (95% CI) = 3.47 (2.15-5.61), adjusted P value < 0.0001), overdominant (AG versus AA + GG: OR (95% CI) = 0.62 (0.45-0.87), adjusted P value = 0.0092) and log-additive models (OR (95% CI) = 1.45 (1.15-1.83), adjusted P value = 0.0034). When comparing allele/genotype frequencies of this SNP between suicide victims and soft suicide attempters, significant associations were found in allelic, codominant, recessive and log-additive models. The AG haplotype (rs11833579 and rs3806263, respectively) was significantly less prevalent among suicide victims compared with controls (OR (95% CI) = 0.37 (0.26-0.52), adjusted P value < 0.0001). This haplotype was also less prevalent among suicide victims vs. soft suicide attempters (OR (95% CI) = 0.43 (0.31-0.61), adjusted P value < 0.0001). The GA haplotype (rs11833579 and rs3806263, respectively) was less frequent among suicide victims compared with controls (OR (95% CI) = 0.63 (0.45-0.89), adjusted P value = 0.0156). Finally, the AA haplotype was more prevalent among suicide victims compared with both controls (OR (95% CI) = 2.37 (1.56-3.6), adjusted P value = 0.0002) and soft suicide attempters (OR (95% CI) = 1.92 (1.32-2.78), adjusted P value = 0.0012). Thus, these two SNPs might be regarded as genetic determinants of suicide risk in Iranian populations. Further studies in different populations are needed to verify these results.

The impact of gun violence restraining order laws in the U.S. and firearm suicide among older adults: a longitudinal state-level analysis, 2012-2016

BACKGROUND

Older adults complete suicide at a disproportionately higher rate compared to the general population, with firearms the most common means of suicide. State gun laws may be a policy remedy. Less is known about Gun Violence Restricting Order (GVRO) laws, which allow for removal of firearms from people deemed to be a danger to themselves or others, and their effects on suicide rates among older adults. The purpose of this study was to examine the association of state firearm laws with the incidence of firearm, non-firearm-related, and total suicide among older adults, with a focus on GVRO laws.

METHODS

This is a longitudinal study of US states using data from 2012 to 2016. The outcome variables were firearm, non-firearm and total suicide rates among older adults. Predictor variables were [1] total number of gun laws to assess for impact of overall firearm legislation at the state level, and [2] GVRO laws.

RESULTS

The total number of firearm laws, as well as GVRO laws, were negatively associated with firearm-related suicide rate among older adults ages 55-64 and > 65 years-old (p < 0.001). There was a small but significant positive association of total number of firearm laws to non-firearm-related suicide rates and a negative association with total suicide rate. GVRO laws were not significantly associated with non-firearm-related suicide and were negatively associated with total suicide rate.

CONCLUSION

Stricter firearm legislation, as well as GVRO laws, are protective against firearm-relate suicides among older adults.

Health Outcome Prioritization in Alzheimer's Disease: Understanding the Ethical Landscape

BACKGROUND

Dementia has been described as the greatest global health challenge in the 21st Century on account of longevity gains increasing its incidence, escalating health and social care pressures. These pressures highlight ethical, social, and political challenges about healthcare resource allocation, what health improvements matter to patients, and how they are measured. This study highlights the complexity of the ethical landscape, relating particularly to the balances that need to be struck when allocating resources; when measuring and prioritizing outcomes; and when individual preferences are sought.

OBJECTIVE

Health outcome prioritization is the ranking in order of desirability or importance of a set of disease-related objectives and their associated cost or risk. We analyze the complex ethical landscape in which this takes place in the most common dementia, Alzheimer's disease.

METHODS

Narrative review of literature published since 2007, incorporating snowball sampling where necessary. We identified, thematized, and discussed key issues of ethical salience.

RESULTS

Eight areas of ethical salience for outcome prioritization emerged: 1) Public health and distributive justice, 2) Scarcity of resources, 3) Heterogeneity and changing circumstances, 4) Knowledge of treatment, 5) Values and circumstances, 6) Conflicting priorities, 7) Communication, autonomy and caregiver issues, and 8) Disclosure of risk.

CONCLUSION

These areas highlight the difficult balance to be struck when allocating resources, when measuring and prioritizing outcomes, and when individual preferences are sought. We conclude by reflecting on how tools in social sciences and ethics can help address challenges posed by resource allocation, measuring and prioritizing outcomes, and eliciting stakeholder preferences.

Negative Emotions and the Course of Depression During Psychotherapy in Suicidal Older Adults With Depression and Cognitive Impairment

OBJECTIVE

The study examines the relationship of negative emotions with: 1) non-emotional symptoms (e.g., vegetative and physical symptoms) and 2) the course of depression in suicidal older adults with Major Depressive Disorder (MDD) and cognitive impairment treated with psychotherapy.

DESIGN

The authors identified a subgroup of participants (N = 26) who expressed suicidal ideation at Baseline or Week 12 from a randomized controlled trial (RCT) of two psychosocial interventions, Problem Adaptation Therapy (PATH) and Supportive Therapy for Cognitively Impaired. The authors assessed negative emotions, non-emotional symptoms of depression, depression severity, and suicidal ideation at entry, week 4, week 8, and week 12.

PARTICIPANTS

Participants were 65 years and older and had a diagnosis of unipolar depression, varying degrees of cognitive impairment (up to moderate dementia) and suicidal ideation.

SETTING

The study was conducted in the Outpatient Department of New York Presbyterian/Weill Cornell Medicine in Westchester, NY.

MEASUREMENTS

Negative emotions and non-emotional items were identified with the 24-item Hamilton Depression Rating Scale (Ham-D).

RESULTS

Among participants with suicidal ideation, the reduction in negative emotions from baseline to week 4, week 4 to week 8, and week 8 to week 12 was significantly associated with the reduction in non-emotional symptoms of depression at weeks 4, 8, and 12 (F_{(1, 35)} = 6.20, p = 0.02) and with the reduction in overall depression severity at weeks 4, 8, and 12 (F_{(1, 35)} = 26.63, p <0.0001) after controlling for depression severity at baseline (HAM-D total score) and time trends.

CONCLUSION

Our findings may guide the treatment of older patients with depression and suicidal ideation to help reduce depression and suicide risk.

Self-harm in the very old one year later: has anything changed?

OBJECTIVES

To follow-up a cohort of older people who self-harmed, their carer, and general practitioner (GP) and examine their reflections on the self-harm, care experiences, and outcomes.

DESIGN

Qualitative in-depth interviews.

SETTING

Two teaching hospitals and associated community services.

PARTICIPANTS

Twelve-month follow-up of participants aged 80 or older who self-harmed, their nominated carers, and GPs.

MEASUREMENTS

A geriatric psychiatrist gathered data through patient and carer interviews using a narrative inquiry approach and from medical records. Interviews were audio recorded and transcribed. N-VIVO facilitated data organization for thematic analysis. Questionnaires sent to the patient's GP examined their perspectives and aspects of care relating to the self-harm.

RESULTS

Nineteen patients (63% baseline sample), 29 carers (90.6%), and 11 GPs (36.7%) were available at follow-up. Themes emerging from patients were "denial and secrets;" "endless suffering;" "more invalidation;" "being heard;" and "miserable in care." Themes from carer interviews were "denial and secrets;" "patient's persistent wish to die;" "abandonment by clinicians;" "unending burden for the carer;" and "distress regarding placement." General practitioner themes were "the problem is fixed;" "the troops have arrived;" and "I understand."

CONCLUSIONS

Factors contributing to self-harm persisted at follow-up. Positive and negative responses were identified in the older person's system, highlighting areas for potential intervention. A conceptual framework for understanding self-harm in the very old was derived that emphasized the importance of understanding individual needs, the interpersonal context of the older person, and carer burden. Interventions should improve communication, facilitate shared understanding of perspectives, and provide support at all levels.

Suicide in Parkinson's disease

Persons with Parkinson's disease (PwP) have many known risk factors for suicide and suicidal ideation (SI). Despite this, there is limited understanding of suicidality in this population. We conducted a systematic review to synthesise the available literature on suicidality in PwP and highlight areas for potential intervention and further research. We identified 116 articles discussing SI, suicidal behaviours, suicide attempts and/or fatal suicide in PwP. These articles describe prevalence, suicide methods, risk factors for suicide and SI and treatment of suicidality. In this review, we summarise the current literature and provide suggestions for how clinicians can identify and treat PwP who are at risk for suicide, for example, through aggressive treatment of depression and improved screening for access to lethal means.

AD molecular: PET amyloid imaging across the Alzheimer's disease spectrum: From disease mechanisms to prevention

The advent of amyloid-beta (Aβ) positron emission tomography (PET) imaging has transformed the field of Alzheimer's disease (AD) by enabling the quantification of cortical Aβ accumulation and propagation in vivo. This revolutionary tool has made it possible to measure direct associations between Aβ and other AD biomarkers, to identify factors that influence Aβ accumulation and to redefine entry criteria into clinical trials as well as measure drug target engagement. This chapter summarizes the main findings on the associations of Aβ with other biomarkers of disease progression across the AD spectrum. It discusses investigations of the timing at which Aβ pathology starts to accumulate, demonstrates the clinical utility of Aβ PET imaging and discusses some ethical implications. Finally, it presents genetic and potentially modifiable lifestyle factors that might influence Aβ accumulation and therefore be targets for AD prevention.

Stakeholders' Views on Early Diagnosis for Alzheimer's Disease, Clinical Trial Participation and Amyloid PET Disclosure: A Focus Group Study

Detection of Alzheimer's disease (AD) in an early stage is receiving increasing attention for a number of reasons, such as the failure of drug trials in more advanced disease stages, the demographic evolution, the financial impact of AD, and the approval of amyloid tracers for clinical use. Five focus group interviews with stakeholders (healthy elderly, informal caregivers, nursing staff, researchers, and clinicians) were conducted.. The verbatim transcripts were analysed via the Nvivo 11 software. Most stakeholder groups wanted to know their own amyloid PET scan result. However, differences occurred between FGs: two groups (informal caregivers and researchers) wanted to know, whilst in the three other groups (healthy elderly, nursing staff, and clinicians) FG members opted not to know or were still in doubt about their decision. Stakeholders provided insight into their reasons for wanting to know their amyloid PET scan result (e.g., the need for clarity, to inform relatives, to make arrangements), for not wanting to know their result, or why they were in doubt about their decision (e.g., fear of AD, not wanting to burden their social environment). Several advantages (e.g., to know what is going on with their health, to plan for the future) and disadvantages (e.g., absence of a disease modifying treatment, risks when undergoing tests) were mentioned as part of knowing their amyloid PET scan result. Certain considerations were clustered in a grey zone, in between advantage and disadvantage, such as the emotional consequences. Clinicians, researchers, and policymakers ought to be aware of the diversity of reasons for (not) wanting to know their result and how possible benefits and risks can be viewed differently. The current findings are of importance for future early diagnosis and disclosure of results in the research setting.

Suicide Among Persons With Dementia, Georgia, 2013 to 2016

INTRODUCTION

Findings from studies examining the relationship between dementia and suicide have been inconsistent. This study examined the characteristics, precipitants, and risk factors for suicide among persons with dementia.

METHODS

Data from the Georgia Alzheimer's Disease and Related Dementia registry were linked with 2013 to 2016 data from Georgia Vital Records and Georgia Violent Death Reporting System. Descriptive statistics were calculated and logistic regression was used to examine risk factors for suicide.

RESULTS

Ninety-one Georgia residents with dementia who died by suicide were identified. Among decedents with known circumstances, common precipitants included depressed mood (38.7%) and physical health problems (72.6%). Suicide rate among persons with dementia was 9.3 per 100 000 person-years overall and substantially higher among those diagnosed in the past 12 months (424.5/100 000 person-years). Being male, dementia diagnosis before age 65, and a recent diagnosis of dementia independently predicted suicide, but not depression or cardiovascular diseases.

CONCLUSION

Prevention strategies that identify at-risk individuals, provide support, and ensure continuity of care for persons diagnosed with dementia may help reduce suicide in this population.

Analysis of the risk and risk factors for injury in people with and without dementia: a 14-year, retrospective, matched cohort study

BACKGROUND

Most previous studies on dementia and injuries have focused on a particular type of injury, and few studies have investigated overall injury in people with dementia. In this study, we investigated the risk factors and risk of overall injury, including the diagnosis, cause, and intentionality of injury, in people with and without dementia in Taiwan.

METHODS

We collected relevant data between 2000 and 2013 from the National Health Insurance Research Database (NHIRD). Overall, 455,630 cases, consisting of 91,126 people with dementia and 364,504 people without dementia, were included in this study and we performed subgroup analysis. A multivariate Cox proportional hazards regression analysis was used to determine the risk of injuries.

RESULTS

The 14-year follow-up data showed that people with dementia had a higher risk of injury-related hospitalization than did people without dementia (19.92% vs 18.86%, hazard ratio (HR) = 1.070, p < 0.001). Regarding the cause of injury, people with dementia were more likely to be hospitalized due to suffocation (HR = 2.301, p < 0.001), accidental drug poisoning (HR = 1.485, p < 0.001), or falls (HR = 1.076, p < 0.001), and were less likely to be hospitalized due to suicide or self-inflicted injury (HR = 0.670, p < 0.001) or a traffic accident (HR = 0.510, p < 0.001) than were people without dementia. Subgroup analysis showed that people with dementia with any of the three subtypes of dementia were at a higher risk of homicide or abuse than were people without dementia (vascular dementia, HR = 2.079, p < 0.001; Alzheimer's disease, HR = 1.156, p < 0.001; other dementia, HR = 1.421, p < 0.001). The risk factors for overall injury included dementia diagnosis, female gender, age 65-74 years, and seeking medical attention for an injury within the past year.

CONCLUSION

People with dementia are at a higher risk of injury-related hospitalization than people without dementia. The results of this study provide a reference for preventing suffocation, drug poisoning, and falls in people with dementia. In addition, government agencies should pay attention to and intervene in cases of abuse suffered by people with dementia.

Alzheimer's Disease - Perspective from Political Science: Public Policy Issues

The paper outlines the policy context and summarizes the numerous policy issues that AD raises from the more generic to the unique. It posits that strong public fears of AD and its future prevalence projections and costs, raise increasingly difficult policy dilemmas. After reviewing the costs in human lives and money and discussing the latest U.S. policy initiatives, the paper presents two policy areas as examples the demanding policy decisions we face. The first focuses on the basic regulatory function of protecting the public from those who would exploit these fears. The second centers on the well-debated issues of advance directives and euthanasia that surround AD. Although more dialogue, education and research funding are needed to best serve the interests of AD patients and families as well as society at large, this will be challenging because of the strong feelings and divisions AD engenders.

At, with and beyond risk: expectations of living with the possibility of future dementia

Biomedical research aimed at the development of therapies for chronic and late-onset conditions increasingly concentrates on the early treatment of symptom-less disease. This broad trend is evidenced in prominent shifts in contemporary dementia research. Revised diagnostic criteria and new approaches to clinical trials propose a focus on earlier stages of disease and prompt concerns about the implications of communicating test results associated with the risk of developing dementia when no effective treatments are available. This article examines expectations of the implications of learning test results related to dementia risk, based on focus group research conducted in the UK and Spain. It points to the extended social and temporal aspects of the dementia risk experience. Three key dimensions of this risk experience are elaborated: living 'at risk', represented in efforts to reduce risk and plan for the future; 'with risk', through vigilance towards cognitive health and earlier or prolonged contact with healthcare services; and finally, 'beyond risk' through a cessation of the self in its current social, legal and financial form.

Review of the Ethical Issues of a Biomarker-Based Diagnoses in the Early Stage of Alzheimer's Disease

BACKGROUND

Today, many healthcare or dementia organizations, clinicians, and companies emphasize the importance of detection of Alzheimer's disease in an early phase. This idea has gained considerable momentum due to the development of biomarkers, the recent FDA and EMA approval of three amyloid tracers, and the failure of a number of recent therapeutic trials conducted in the early dementia phase. On the one hand, an early etiological diagnosis can lead to early and more efficacious intervention. On the other hand, it is questioned how early an etiological diagnosis is beneficial to the patient. Here we consider ethical issues related to the process of biomarker testing and the impact on the diagnostic disclosure to patients with mild cognitive impairment due to prodromal Alzheimer's disease.

METHODS

A systematic review of the theoretical bioethics literature was performed by using electronic databases. The review was limited to articles published in English between 2003 and 2016.

RESULTS

A total of twenty articles were included in our effort to make an analysis of the ethical challenges. One of the biggest challenges was the uncertainty and the predictive value of the biomarker-based diagnosis where patients can be amyloid positive without full certainty whether or when they will develop symptomatic decline due to Alzheimer's disease. Another challenge was the tension between the right to know versus the wish not to know, the limited efficacy of currently available treatment options, and the opportunities and consequences after receiving such an early diagnosis.

CONCLUSION

Based on the results and the additional comments in the discussion, several unanswered questions emerged. Therefore, careful consideration of all these ethical issues is required before the disclosure of a biomarker-based diagnosis to the patient with mild cognitive impairment due to Alzheimer's disease.

Completed suicide in an autopsy-confirmed case of early onset Alzheimer's disease

We report a case of a 57-year-old male with clinically diagnosed and autopsy-confirmed early onset Alzheimer's disease who completed suicide by gunshot wound to the chest. This case has several unique aspects that have not been discussed in previous case reports of completed suicide in Alzheimer's disease. In particular, our patient's death was highly planned with successful compensation for his cognitive deficits. After all firearms had been removed from the home as a safety precaution, he obtained a new weapon, hid it and left himself cues to find and use it. The case is discussed in the context of literature differentiating the neural circuitry propagating impulsive versus planned suicidal acts.

Amnestic MCI patients' experiences after disclosure of their amyloid PET result in a research context

BACKGROUND

Biomarkers such as amyloid imaging are increasingly used for diagnosis in the early stages of Alzheimer's disease. Very few studies have examined this from the perspective of the patient. To date, there is only limited evidence about how patients experience and value disclosure in an early disease stage.

METHODS

Semistructured interviews were carried out with 38 patients with amnestic mild cognitive impairment as part of an investigator-driven diagnostic trial (EudraCT, 2013-004671-12; registered on 20 June 2014) in which participants could opt to know the binary outcome (positive/negative) result of their amyloid positron emission tomography (PET) scan. Verbatim transcripts of the interviews were evaluated using qualitative content analysis and NVivo 11 software.

RESULTS

Eight of 38 patients received a positive amyloid PET scan result, and the remaining 30 patients received a negative amyloid PET scan result. After disclosure of the result to the patients, we interviewed each patient twice: 2 weeks after disclosure and 6 months after disclosure. Patients had difficulties in repeating the exact words used during disclosure of their amyloid PET scan result by the neurologist; yet, they could recall the core message of the result in their own words. Some patients were confused by the terminology of an amyloid-positive/negative test result. At 6 months, two of eight patients with a positive amyloid PET scan result experienced emotional difficulties (sadness, feeling worried). Three of 30 patients with a negative amyloid PET scan result started to doubt whether they had received the correct result. Patients reported that they experienced advantages after the disclosure, such as information about their health status, the possibility of making practical arrangements, medication, enjoying life more, and a positive impact on relationships. They also reported disadvantages following disclosure, such as having emotional difficulties, feeling worried about when their symptoms might worsen, the risk of a more patronizing attitude by relatives, and the possibility of a wrong diagnosis.

CONCLUSIONS

This exploratory study shows that the majority of patients can accurately recall the information received during disclosure. The experienced advantages and disadvantages reported by our patients depended on the outcome of the result (positive or negative) and the interval of the conducted interview (2 weeks or 6 months after amyloid PET disclosure). Discrepancies were found between patients' expectations according to the interview prior to amyloid PET disclosure (Vanderschaeghe et al. [Neuroethics. 2017;10:281-97]) and their actual experiences after their amyloid PET disclosure.

[Dementia - View of sufferers and their relatives]

Dementia is the leading cause of cognitive and functional impairment in old age; however, within the scientific community this complex disease is predominantly viewed from a narrow neurobiological and medical perspective, whereas the subjective aspects of dementia, particularly the psychological and social consequences, albeit severe are more or less neglected. In this article the subjective side of experiences of persons with dementia and their relatives are discussed and special aspects of their specific problems and needs during the course of the illness are described. The progress made in supporting persons with dementia and their carers during the last decades is considered and areas where further progress is necessary are delineated.

Disease awareness may increase risk of suicide in young onset dementia: A case report

Studies report that people with young onset Alzheimer's disease (YOAD) have higher levels of disease awareness compared to those with late onset AD. We report a case of a man with YOAD who had preserved awareness of disease, depression and risk of suicide associated with the development of the dementia. Cognitive functioning, disease severity, depressive symptoms and awareness of disease were assessed using validated measures. The person with YOAD showed a moderate level of disease severity and high degree of dependence for activities of daily living. There was recognition of memory problems and routine changes with presence of intense pessimism, low self-esteem and suicidal ideation. This case points to the existence of specific issues related to young onset dementia and the clinical importance of identifying and treating patients who might be aware of their condition.

Suicide and assisted dying in dementia: what we know and what we need to know. A narrative literature review

BACKGROUND

Evidence-based data on prevalence and risk factors of suicidal intentions and behavior in dementia are as scarce as the data on assisted dying. The present literature review aimed on summarizing the current knowledge and provides a critical discussion of the results.

METHODS

A systematic narrative literature review was performed using Medline, Cochrane Library, EMBASE, PSYNDEX, PSYCINFO, Sowiport, and Social Sciences Citation Index literature.

RESULTS

Dementia as a whole does not appear to be a risk factor for suicide completion. Nonetheless some subgroups of patients with dementia apparently have an increased risk for suicidal behavior, such as patients with psychiatric comorbidities (particularly depression) and of younger age. Furthermore, a recent diagnosis of dementia, semantic dementia, and previous suicide attempts most probably elevate the risk for suicidal intentions and behavior. The impact of other potential risk factors, such as patient's cognitive impairment profile, behavioral disturbances, social isolation, or a biomarker based presymptomatic diagnosis has not yet been investigated. Assisted dying in dementia is rare but numbers seem to increase in regions where it is legally permitted.

CONCLUSION

Most studies that had investigated the prevalence and risk factors for suicide in dementia had significant methodological limitations. Large prospective studies need to be conducted in order to evaluate risk factors for suicide and assisted suicide in patients with dementia and persons with very early or presymptomatic diagnoses of dementia. In clinical practice, known risk factors for suicide should be assessed in a standardized way so that appropriate action can be taken when necessary.
