Introduction Delirium is frequently multifactorial, and causes are often missed in clinical practice. The Aetiology in Delirium - Diagnostic Support Tool (AiD-DST) was developed to improve recognition of the causes. We undertook an evaluation of an electronic version of AiD-DST. Methods A development and evaluation life cycle of improvement was used. In phase 1, alpha testing among the development group evaluated technical performance of AiD-DST. In phase 2, we performed a cycle of beta testing among junior doctors to assess impressions of AiD-DST using Think Aloud methodology. We grouped responses into themes and made changes to AiD-DST by the development group accordingly. In phase 3, usability and acceptance of AiD-DST was assessed using the mHealth App Usability Questionnaire (MAUQ). Results In phase 1, software issues were identified, and modifications made. In phase 2, feedback was obtained from 29 junior doctors. Three cycles of feedback were obtained. The number of items identified after each cycle were 20, 12 and 7, respectively. Content was grouped into themes of; ‘style and grammar’, ‘formatting’, ‘IT’, ‘missed diagnosis’ and ‘other concerns.’ In phase 3, 20 participants completed MAUQ questionnaire. Overall, the average score was 6.36 (SD=0.8) with 7 as the highest attainable score. This translates to agreement up to strong agreement concerning usability of AiD-DST. Conclusion After a process of optimisation, AiD-DST has been shown to be a usable and potentially useful diagnostic support tool to help junior doctors identify cause(s) of delirium. An implementation study is planned.

© 2020 American Psychological Association. Dreams and daydreams are as beguiling as they are intangible. Both share many features, from neurobiology to the sensed experience. Nevertheless, the specific narrative relationship between both, if any, remains uncertain. Theories of dream origins are many: from the psychodynamic royal road, to biological theories including Hebbian-based memory consolidation and a unified quantum brain theory that extends to waking and dreaming alike. Both the ephemeral nature of dreams, and an inability to simultaneously study their content and biology, renders them difficult to research from a conventional biomedical perspective. This leaves agreement on the fundamental properties of dreams as ambiguous, and even the state of consciousness enjoyed during sleep is contested. What is known is that the qualia and neurophysiological signature of dreams and daydreaming share many features. We propose further, from a subjective experientialist position, that dream content is specifically derived from daydreaming or mindful wandering (subserved by the default mode network). If substantiated, this concept offers a new insight into the origin of dreams.

Dysfunction of the cholinergic basal forebrain (BF) neurotransmitter system, including cholinergic axon denervation of the cortex, plays an important role in cognitive decline and dementia. A validated method to directly quantify cortical cholinergic terminal integrity enables exploration of the involvement of this system in diverse cognitive profiles associated with dementia, particularly at a prodromal stage. In this study, we used the radiotracer [

Le délirium est un problème de santé majeur aux conséquences potentiellement graves. Malheureusement, la prise en charge de ce trouble est souvent sous-optimale. Nous considérons que les lacunes dans les soins offerts aux patients avec délirium sont liées aux particularités de cette condition, qui affecte la perception du « soi » de la personne qui en souffre. Cette atteinte entraîne un comportement hors de contrôle chez la personne avec délirium et l'expose à une déshumanisation mécaniste. Une solution consisterait à favoriser une vision élargie du « soi », inspirée de la philosophie et des sciences cognitives récentes, afin d'aider les cliniciens dans la compréhension du comportement pathologique en tant que manifestation de la perturbation de la pensée. Une approche centrée sur l'éthique des soins, intégrant un nouveau cadre pour la relation patient-soignant, est proposée. Considérées dans leur ensemble, les propositions novatrices émises pourraient faciliter l'élaboration d'un cadre de pratiques et de relations plus attentionnées et plus efficaces pour le traitement du délirium.Delirium is a major health care problem with potentially serious consequences. Sub-optimal management is an unfortunate but pervasive hallmark of the disorder. We argue that lapses in the care of delirious patients are related to the peculiarities of delirium as a disorder that affects the “self” of the sufferer. Therefore, corruption of self renders behaviour outside the control of the delirious individual and places the person at risk of mechanistic dehumanisation. A proposed solution is to foster an expanded view of the self, taken from recent philosophy and cognitive science, which would allow the clinician to understand pathological behaviour as indicative of disruption to thought. An ethics of care approach that reframes the patient/carer relationship is proposed. These unique propositions could, together, facilitate the development of a framework of more caring and effective practices and relationships for delirium treatment.

Background Persons with dementia commonly experience a range of behavioural and psychological symptoms, including agitation, aggression, perceptual disturbances, and depression. While psychotropic medications are regularly prescribed to mitigate these symptoms, these agents also carry a broad adverse effect profile. This study aimed to characterize psychotropic medication use in patients with dementia, as well as identify prescribing factors associated with falls in this cohort. Methods This retrospective study collected longitudinal demographic and medication data from all patients admitted to a neuro‐cognitive unit at an Australian metropolitan hospital over a 2‐year period. Psychotropic polypharmacy and psychotropic agent use per patient‐fortnight were investigated for their association with inpatient falls. Results All patients (n = 147) were prescribed at least one psychotropic medication, with 96% receiving anti‐psychotic medications and 90% receiving benzodiazepines. Patient fall rate was significantly associated with anticholinergic drug use (Incidence rate ratio: 2.2; P, Patients with dementia are often prescribed psychotropic medications, including antipsychotics and benzodiazepines, to relieve the behavioural and psychological symptoms of dementia. However, this must be counterbalanced against psychotropic adverse effects. Our study demonstrates that anticholinergic medications and psychotropic polypharmacy are associated with fall incidence in patients with dementia.

Delirium is a common disorder in hospitalized older adults and the defining characteristic is a disturbance of consciousness. Unfortunately, there are currently no testable measures of consciousness as pertains to its disruption in delirium. Not surprisingly rates of recognition of delirium suffer. Arguably, a greater understanding of the quantum of consciousness may improve delirium diagnosis through better diagnostic tools. Candidate dimensions of consciousness derived from fields of psychology, psychiatry, and philosophy are discussed and relevance to delirium explored. Based upon existing literature in the field of consciousness we identify the pre-reflective state, experiential awareness, and functional networks as candidate sites that may be affected in delirium. Opportunities for clinical instrument development and how these tools can be tested are discussed. We conclude that consciousness content may not hold to a unitary measurement, but facets of its integrity that are impacted in delirium are open to further exploration. Disorders in pre-reflective status, experiential awareness, and functional networks may represent the measurable "rabbit holes" of consciousness disturbance.

Background recognition of the multifactorial causes of delirium represents a clinical challenge. Objectives to develop and show proof of principle of a diagnostic support tool (DST) for identification of causes of delirium. Methods stage 1—development of the aetiology in delirium-diagnostic support tool (AiD-DST); stage 2—validation of the AiD-DST against reference standard diagnosis, based on clinical assessment from two independent consultant geriatricians. Results a series of eight steps AiD-DST were formulated by an expert group to identify possible causes of delirium. Forty inpatients admitted to a general medical unit with a consultant physician/geriatrician diagnosis of delirium were recruited, consented and reviewed against the AiD-DST. Mean age was 85.1 (standard deviation 7.9) years and 26 (65%) of participants were female. Participants had multiple chronic co-morbidities [median Charlson Comorbidity Index 7; interquartile range (IQR 6–9)] and median number of medications was 8 (IQR 6–11.75). Median number of causes of delirium detected on AiD-DST was 3 (IQR 3–4) versus 5 (IQR 3–6) using the reference standard diagnosis, with sensitivity of 88.8% (95% confidence interval, 81.6–93.9%) and specificity of 71.8% (63–79.5%). Conclusions the aetiology in delirium DST shows promise in the identification of cause(s) in delirium.

Background: Clinicians frequently use their own judgement to assess patient’s hydration status although there is limited evidence for the diagnostic utility of any individual clinical symptom. Hence, the aim of this study was to compare the diagnostic accuracy of clinically assessed dehydration in older hospital patients (using multiple symptoms), versus dehydration measured using serum-calculated osmolality (CO) as the reference standard. Method: Participants were 44 hospital patients aged ≥ 60 years. Dehydration was assessed clinically and pathologically (CO) within 24 hours of admission and at study exit. Indicators of diagnostic accuracy were calculated. Results: Clinicians identified 27% of patients as dehydrated at admission, and 19% at exit, compared to 19% and 16% using CO. Agreement between the measures was fair at admission and poor at exit. Clinical assessment showed poor sensitivity for predicting dehydration with reasonable specificity. Conclusions: Compared to the use of CO, clinical assessment of dehydration in older patients was poor. Given that failure to identify dehydration in this population may have serious consequences, we recommend that clinicians do not rely upon their own assessments without also using the reference standard.

The application of transcatheter aortic valve implantation (TAVI) to high-surgical-risk and inoperable patients with severe aortic stenosis (AS) is gaining widespread acceptance with a burgeoning supportive evidence base.1 The benefits associated with the application of this technique, however, are mitigated by the occurrence of major, disabling stroke with associated increased mortality and early-reduced quality of life.2 Despite this, the risk/benefit ratio has been considered acceptable in appropriately selected patients given the outcomes of alternate management options in these high-risk and inoperable populations.3,4 The incidence of cerebrovascular events (CVEs) subsequent to TAVI exceeds that after any other cardiac intervention or valve surgery, most notably in the acute periprocedural period, diminishing over the subsequent 2 months.5 This elevated early risk reflects the increased incidence of ischemic stroke thought secondary to particulate emboli dislodged by the procedure itself or as a result of thromboembolism.6 In fact, cerebral embolism is a universal finding associated with these procedures.7 Most events, however, are subclinical or silent, with clinically apparent CVEs representing but the tip-of-the-iceberg. As a result of the difficulty ascertaining these subclinical events, the true association between TAVI and neurological injury is unknown and the harm potentially underestimated. This article aims to comprehensively review neurological injury in TAVI, with an emphasis on cerebrovascular disease. Evidence and current concepts regarding pathophysiological mechanisms, risk factors, and prognostic implications will be discussed and risk reduction strategies explored. CVEs post-TAVI are classified based on clinical severity as illustrated in Figure 1. Incomplete reporting and variable definitions of clinically apparent events and disregard of subclinical events have limited the true evaluation of CVEs associated with TAVI. Consequently, in 2011 the Valve Academic Research Consortium published a consensus report on standardized end point definitions, including stroke, which were expanded and refined in …

Objective(s): A new model of care for the management of patients with delirium was developed and evaluated. Method: A 4-bedded Close Observation Unit (COU) was introduced. The model comprised an education strategy for assistants in nursing (AIN), environmental adaptations and AIN to patient ratio of 1:4. Outcomes in all patients with delirium before and after introduction of the new model of care were compared. Results: 105 patients were admitted to COU, of whom 100 (95%) were diagnosed with delirium. In-hospital mortality improved after introduction of the unit (15% versus 5%; p=0.002) without significant change in length of stay, discharge destination or falls frequency. Conclusion: A dedicated unit for delirium management within medicine achieved a reduction in mortality.

Background: Consciousness, the medium of sentient thought, requires integrity of functional networks and their connectivity. In health, they function as a co-operative but mutually exclusive paradigm of introspection versus external awareness subserved via the Default Mode Network and Task Positive State, respectively. Higher thinking in the conscious state is then segregated according to need. There is research evidence to suggest that functional networks may be impacted in disorders of consciousness and conceptual support for a mechanistic role in delirium. This potentially central aspect of delirium manifestation is relatively unexplored. Objective: This article describes the role of disrupted functional networks in delirium. How this relates to current understanding of delirium neurobiology and the ramifications for clinical diagnosis is discussed. Method: A review of the role of functional networks, particularly DMN and TPN, has been undertaken with respect to health and delirium. An exploration of how symptoms of delirium may be related to functional network aberrancy has been undertaken. Implications for research and clinical practice in delirium have been presented. Results: In delirium, a disturbance of consciousness, the DMN is pathologically co-activated and functional cortical connectivity is compromised. The clinical correlate is of an experiential singularity where internal and external drivers become indistinguishable, reality and delusion merge and the notion of self is effaced. Our group propose that functional network disruption in conjunction with cortical disconnectivity is central to the mechanism of delirium. Clinical tools may exploit the neurobiology of delirium to improve its diagnosis and an example of such a simple screening instrument (SQeeC) is provided. Conclusion: Functional networks are critically disrupted in delirium and may be central to clinical features. A better understanding of the neurobiology of delirium will generate research opportunities with potential for therapeutic gains in detection, diagnosis, and management.

Background The application of transcatheter aortic valve implantation ( TAVI ) to intermediate‐risk patients is a controversial issue. Of concern, neurological injury in this group remains poorly defined. Among high‐risk and inoperable patients, subclinical injury is reported on average in 75% undergoing the procedure. Although this attendant risk may be acceptable in higher‐risk patients, it may not be so in those of lower risk. Methods and Results Forty patients undergoing TAVI with the Edwards SAPIEN ‐ XT ™ prosthesis were prospectively studied. Patients were of intermediate surgical risk, with a mean±standard deviation Society of Thoracic Surgeons score of 5.1±2.5% and a Euro SCORE II of 4.8±2.4%; participant age was 82±7 years. Clinically apparent injury was assessed by serial National Institutes of Health Stroke Scale assessments, Montreal Cognitive Assessments (Mo CA ), and with the Confusion Assessment Method. These identified 1 (2.5%) minor stroke, 1 (2.5%) episode of postoperative delirium, and 2 patients (5%) with significant postoperative cognitive dysfunction. Subclinical neurological injury was assessed using brain magnetic resonance imaging, including diffusion‐weighted imaging ( DWI ) sequences preprocedure and at 3±1 days postprocedure. This identified 68 new DWI lesions present in 60% of participants, with a median±interquartile range of 1±3 lesions/patient and volumes of infarction of 24±19 μL/lesion and 89±218 μL/patient. DWI lesions were associated with a statistically significant reduction in early cognition (mean ΔMo CA −3.5±1.7) without effect on cognition, quality of life, or functional capacity at 6 months. Conclusions Objectively measured subclinical neurological injuries remain a concern in intermediate‐risk patients undergoing TAVI and are likely to manifest with early neurocognitive changes.

Background: delirium and frailty are common among hospitalised older people but delirium is often missed and frailty considered difficult to measure in clinical practice. Objective: to explore the relationship between delirium and frailty in older inpatients and determine their impact on survival. Design and setting: the prospective cohort study of 273 patients aged ≥75 years. Measures: patients were screened for delirium at presentation and on alternate days throughout their hospital stay. Frailty status was measured by an index of accumulated deficits (FI), giving a potential score from 0 (no deficits) to 1.0 (all 33 deficits), with 0.25 used as the cut-off between ‘fit’ and ‘frail’. Results: delirium was detected in 102 patients (mean FI: 0.33) and excluded in 171 (mean FI: 0.18) (P < 0.005); 111 patients were frail. Among patients with delirium, the median survival in fit patients was 359 days (95% CI: 118–600) compared with 88 days for those who were frail (95% CI: 5–171; P < 0.05). Conclusion: delirium was associated with higher levels of frailty: the identification of frail patients may help to target those at a greatest risk of delirium. Survival following delirium was poor with the combination of frailty and delirium conferring a particularly bleak prognosis.

Background: multidisciplinary rehabilitation is of proven benefit in the management of older inpatients. However, the identification of patients who will do well with rehabilitation currently lacks a strong evidence base. Objectives: the aims of this study were to compare the importance of chorological age, gender, co-morbidities and frailty in the prediction of adverse outcomes for patients admitted to an acute geriatric rehabilitation ward. Design: prospective observational cohort study. Subjects and setting: two hundred and sixty-five patients admitted consecutively to an acute geriatric rehabilitation ward at a tertiary care teaching hospital. Methods: frailty status was measured by an index of accumulated deficits, giving a potential score from 0 (no deficits) to 1.0 (all 40 deficits present). Patients were stratified into three outcomes: good (discharged to original residence within 28 days), intermediate (discharged to original residence but longer hospital stay) and poor (newly institutionalised or died). Results: patients were old (82.6 ± 8.6 years) and frail (mean frailty index (FI) 0.34 ± 0.09). Frailty status correlated significantly with length of stay and was a predictor of poor functional gain. The odds ratio of intermediate and poor outcome relative to a good outcome was 4.95 (95% CI = 3.21, 7.59; P < 0.001) per unit increase in FI. Chronological age, gender and co-morbidity showed no significant association with outcomes. Conclusion: frailty is associated with adverse rehabilitation outcomes. The FI may have clinical utility, augmenting clinical judgement in the management of older inpatients.

Delirium is a commonly occurring complex neuropsychiatric disorder. Evidence for its treatment based on randomized controlled trials is poor. The aim of this study is to determine the efficacy and acceptability of quetiapine in the treatment of delirium.

While dehydration is common in older patients and is associated with poor outcomes, it has been infrequently studied in the hospital setting. Thus, the aim of this study was to identify potential barriers and enablers to the maintenance of adequate hydration in older patients in an acute hospital environment. An observational study, involving patients aged 60 years and older admitted to an acute care hospital in Queensland, Australia, was undertaken. Forty-four patients were observed during mealtimes, and chart and room audits were performed to identify hydration management strategies, weight records and the presence or absence of fluid balance charts. Results revealed a number of system and practice-related barriers including patient difficulties with opening fluid containers and low levels of documentation of hydration management strategies. Addressing these issues is an important first step towards improving the management of hydration in medically ill older hospital patients.

Background: Management of patients with delirium presents a challenge. Aims: Supported discharge with Hospital in the Home (HITH) for patients with delirium was developed and evaluated. Methods: Patients admitted acutely to internal medicine and geriatrics, with a diagnosis of delirium were considered for HITH. Patients with a full time career and who lived in their own residence were eligible for the program. Delirium was diagnosed using CAM. Outcomes were compared against historical control. All data was collected prospectively. Results: A total of 89 patients (9.2 per cent) were diagnosed with delirium. Of 31 patients eligible for HITH, 17 had suitable carers. Sixteen patient-caregiver teams were successfully discharged on HITH. Age, frailty score, length of stay and readmissions did not vary significantly between the intervention and control group (N=7). Thirteen patient-carers provided feedback and which was supportive of the intervention. Conclusion: This innovative model of care was feasible and well received. Further studies are recommended.

Background The incidence of clinically apparent stroke in transcatheter aortic valve implantation (TAVI) exceeds that of any other procedure performed by interventional cardiologists and, in the index admission, occurs more than twice as frequently with TAVI than with surgical aortic valve replacement (SAVR). However, this represents only a small component of the vast burden of neurological injury that occurs during TAVI, with recent evidence suggesting that many strokes are clinically silent or only subtly apparent. Additionally, insult may manifest as slight neurocognitive dysfunction rather than overt neurological deficits. Characterisation of the incidence and underlying aetiology of these neurological events may lead to identification of currently unrecognised neuroprotective strategies. Methods The Silent and Apparent Neurological Injury in TAVI (SANITY) Study is a prospective, multicentre, observational study comparing the incidence of neurological injury after TAVI versus SAVR. It introduces an intensive, standardised, formal neurologic and neurocognitive disease assessment for all aortic valve recipients, regardless of intervention (SAVR, TAVI), valve-type (bioprosthetic, Edwards SAPIEN-XT) or access route (sternotomy, transfemoral, transapical or transaortic). Comprehensive monitoring of neurological insult will also be recorded to more fully define and compare the neurological burden of the procedures and identify targets for harm minimisation strategies. Discussion The SANITY study undertakes the most rigorous assessment of neurological injury reported in the literature to date. It attempts to accurately characterise the insult and sustained injury associated with both TAVI and SAVR in an attempt to advance understanding of this complication and associations thus allowing for improved patient selection and procedural modification.

Introduction: hip fracture is expensive in terms of mortality, hospital length of stay (LOS) and consequences for independence. Poor outcome reflects the vulnerability of patients who typically sustain this injury, but the impact of different comorbidities and impairments is complex to understand. We consider this in a prospective cohort study designed to examine how a patients’ frailty index (FI) predicts outcome. Methodology: consecutive patients with low trauma hip fracture were assessed, excluding only those unfit for surgery. Comprehensive Geriatric Assessment (CGA) findings were used to derive a FI for each patient, which was examined alongside other assessment and outcome data from our National Hip Fracture Database (NHFD) submission for these individuals. Results: we describe 178 patients; mean age 81 years, 73.5% female. The mean FI was 0.34 (SD = 0.16), and logistic regression identified abbreviated mental test score and FI as the strongest predictors of poor outcome. When patients were stratified by FI, 56 (31.5%) were in the low-frailty group (FI ≤0.25), 58 (32.5%) in intermediate (FI >0.25–0.4), and 64 (36%) in the high-FI group (FI >0.4). All the patients in the low-FI group returned to their original residence within a mean of 21.6 days. The mean LOS for the intermediate group was 36.3 days compared with 67.8 days in the high-FI group (P< 0.01) while 30-day mortality was 3.4% for the intermediate group compared with 17.2% for the high-FI group (P< 0.001). Conclusions: individual CGA findings proved disappointing as outcome predictors, while FI turned out to be a better predictor of mortality, 30-day residence and length of inpatient stay.

Archetypal symptoms and signs are commonly absent in frail older people who are acutely unwell. This challenges both recognition of illness and monitoring of disease progression in people at high risk of prolonged hospital stays, institutionalization and death.To determine whether bedside assessment of balance and mobility could track acute changes in the health status of older people admitted to hospital.Prospective cohort study.Four hundred nine patients, with a mean age of 81.8 years, admitted to general medical and rehabilitation wards at a tertiary care teaching hospital in Halifax, Nova Scotia. No patient refused assessment, and the only exclusion criterion was age.The Hierarchical Assessment of Balance and Mobility (HABAM) was completed daily during the first 2 weeks of admission. For each patient, frailty status was measured on admission by a Frailty Index based on a Comprehensive Geriatric Assessment (FI-CGA).Death and discharge destination.Poor performance in balance, transfers and mobility was associated with adverse outcomes. Forty-eight percent of patients with the lowest scores in all three domains died, compared with none with the highest scores. The relative risk of death for people who deteriorated during the first 48 h of admission was 17.1 (95% confidence interval: 4.9-60.3). Changes in HABAM scores were related to the discharge destination: patients discharged home showed the greatest rate of improvement, whereas those discharged to institutions stabilised at a lower level of performance. Fitter patients tended to have better performance on admission and faster recovery.Daily bedside observation of mobility and balance allows assessment of acute changes in the health of older people. Frailty slows recovery of mobility and balance, and reduces recovery potential. By identifying patients most vulnerable to adverse outcomes, the HABAM and FI-CGA may facilitate risk stratification in older people admitted to hospital.

Delirium is a disorder affecting consciousness, which gives rise to core clinical features and associated symptoms. Older patients are particularly prone, owing to higher rates of pre-existing cognitive impairment, frailty, co-morbidity and polypharmacy.The aim of this study was to investigate the hypotheses that delirium affects the most vulnerable older adults and is associated with long-term adverse health outcome.This prospective cohort study evaluated 278 medical patients agedor = 75 years admitted acutely to a district general hospital in South Wales. Patients were screened for delirium at presentation and on alternate days throughout their hospital stay. Assessments also included illness severity, preadmission cognition, co-morbidity and functional status. Patients were followed for 5 years to determine rates of institutionalisation and mortality. Number of days in hospital in the 4 years prior to and 5 years after index admission were recorded.Delirium was detected in 103 patients and excluded in 175. Median time to death was 162 days (interquartile range 21-556) for those with delirium compared with 1,444 days (25% mortality 435 days, 75% mortality5 years) for those without (P0.001). After adjusting for multiple confounders, delirium was associated with an increased risk of death (hazard ratio range 2.0-3.5; Por = 0.002). Institutionalisation was higher in the first year following delirium (P = 0.03). While those with delirium tended to be older with more preadmission cognitive impairment, greater functional dependency and more co-morbidity, they did not spend more days in hospital in the 4 years prior to index admission.Delirium is associated with high rates of institutionalisation and an increased risk of death up to 5 years after index event. Prior to delirium, individuals seem to compensate for their vulnerability. The impact of delirium itself, directly or indirectly, may convert vulnerability into adverse outcome.

Background: Populations worldwide are aging and the overall prevalence of dementia at death is now 30%. Since the contemporary social impact of a disease is indicated by the frequency of its newspaper coverage and since obituary notices illuminate conceptions of death, we hypothesized that obituary notices placed by families would reflect societal attitudes to aging and dementia.Methods: We undertook critical discourse analysis of obituaries in representative national and local newspapers in Canada and the U.K.Results: In the 799 obituaries studied, chronological age, suggested donations in memory of the deceased, and donations to dementia charities were each included in significantly more obituaries in Canadian newspapers than in U.K. ones. Military service was explicit for significantly more men aged ≥ 80 years in Canada compared to the U.K. (41% versus 4%; p < 0.05). Of the donations to medical charities, nearly half (n = 117) were to cancer charities and one-fifth (54) to heart and stroke foundations. In the U.K., obituaries for those aged ≥ 70 years were more likely to recommend donations to children's charities (n = 12) or the Royal National Lifeboat Institution (8) than dementia charities (7).Conclusions: Donations to dementia charities were significantly more common in obituaries in Canada than in the U.K. In both countries, donations to medical charities did not reflect disease prevalence or impact to the individual. Societal attitudes in the U.K. may be impacted by the fragmentation of aging research and antipathy to geriatric medicine in the national medical press.
