Abstract We elicit numerical expectations for late-onset dementia and long-term care (LTC) outcomes in the Health and Retirement Study. We provide the first empirical evidence on dementia-risk perceptions among dementia-free older Americans and establish important patterns regarding imprecision of subjective probabilities. Our elicitation distinguishes between precise and imprecise probabilities, while accounting for rounding of reports. Imprecise-probability respondents quantify imprecision using probability intervals. Nearly half of respondents hold imprecise dementia and LTC probabilities, while almost a third of precise-probability respondents round their reports. These proportions decrease substantially when LTC expectations are conditioned on hypothetical knowledge of the dementia state. Among rounding and imprecise-probability respondents, our elicitation yields two measures: an initial rounded or approximated response and a post-probe response, which we interpret as the respondent's true point or interval probability. We study the mapping between the two measures and find that respondents initially tend to over-report small probabilities and under-report large probabilities. Using a specific framework for study of LTC insurance choice with uncertain dementia state, we illustrate the dangers of ignoring imprecise or rounded probabilities for modelling and prediction of insurance demand.

ABSTRACT Current concepts regarding frontotemporal lobar degeneration (FTLD) have evolved rapidly in recent years. Genetically determined FTLD cohorts have broadened our knowledge pertaining to its clinical presentation, neuroimaging findings and demographics. In this study we present a case report of a patient diagnosed with behavioral variant frontotemporal dementia diagnosis in her nineties during hospital admission for a ground-level fall. We believe this case reinforces the pervasive nature of this clinical entity, and may contribute to an increased awareness of this diagnostic possibility in late-onset dementia.

Aims: The aims of this study were to compare quality of life (QOL) in people with young-onset Alzheimer’s (AD) and frontotemporal (FTD) dementia, explore variables associated with QOL, and compare QOL in young-onset dementia (YOD) and late-onset dementia (LOD). Methods: Cross-sectional data from a Nordic multicenter study of 50 community-dwelling participants with AD and 38 with FTD were included. A comparison group consisted of 100 people with LOD. QOL was measured using self-reported Euro-QOL 5-Dimension and the proxy version of Quality of Life in Alzheimer’s Disease (QOL-AD) questionnaire. Neuropsychiatric symptoms and needs were assessed using the Cornell Scale for Depression in Dementia (CSDD), Neuropsychiatric Inventory (NPI), and Camberwell Assessment of Needs in the Elderly. Multiple linear regression and multilevel modeling was used to determine variables associated with QOL. Results: We found no differences between the two YOD groups in QOL. The variables associated with QOL were scores on the CSDD, NPI, and unmet needs. The proxy QOL-AD score in YOD was significantly higher compared to LOD (median 36.0 [IQR 10.0] vs. 33.0 [IQR 9.0]). Conclusion: The QOL in Nordic people with YOD was better compared to people with LOD. Our results show depressive symptoms to be associated with QOL irrespective of age and diagnosis.

ABSTRACT:Background:Young-onset dementia (YOD) is defined as the onset of dementia symptoms before the age of 65 years and accounts for 2–8% of dementia. YOD patients and their caregivers face unique challenges in diagnosis and management. We aimed to compare the characteristics of rural YOD and late-onset dementia (LOD) patients at a rural and remote memory clinic in Western Canada.Methods:A total of 333 consecutive patients (YOD = 61, LOD = 272) at a rural and remote memory clinic between March 2004 and July 2016 were included in this study. Each patient had neuropsychological assessment. Health, mood, function, behaviour and social factors were also measured. Both groups were compared using χ2 tests and independent sample tests.Results:YOD patients were more likely to be married, employed, current smokers and highly educated. They reported fewer cognitive symptoms, but had more depressive symptoms. YOD patients were less likely to live alone and use homecare services. YOD caregivers were also more likely to be a spouse and had higher levels of distress than LOD caregivers. Both YOD and LOD patient groups were equally likely to have a driver’s licence.Conclusions:Our findings indicate YOD and LOD patients have distinct characteristics and services must be modified to better meet YOD patient needs. In particular, the use of homecare services and caregiver support may alleviate the higher levels of distress found in YOD patients and their caregivers. Additional research should be directed to addressing YOD patient depression, caregiver distress and barriers to services.

Late Onset Dementia

Atrial fibrillation (AF) is considered a risk factor for dementia, especially in the elderly. However, the association between the two diseases is not well identified in different age subgroups. The association of incident AF with the development of dementia was assessed from 1 January 2005, to 31 December 2013, in 428,262 participants from a longitudinal cohort (the Korea National Health Insurance Service-Health Screening cohort). In total, 10,983 participants were diagnosed with incident AF during the follow-up period. The incidence of dementia was 11.3 and 3.0 per 1000 person-years in the incident-AF and without-AF groups, respectively. After adjustment for clinical variables, the risk of dementia was significantly elevated by incident AF, with a hazard ratio (HR) of 1.98 (95% confidence interval [CI]: 1.80–2.17, p < 0.001), even after censoring for stroke (HR: 1.74, 95% CI: 1.55–1.94, p < 0.001). The HRs of incident AF for dementia onset before the age of 65 (early-onset dementia) and for onset after the age of 65 (late-onset dementia) were 2.91 (95% CI: 1.93–4.41) and 1.67 (95% CI: 1.49–1.87), respectively. Younger participants with AF were more prone to dementia development than older participants with AF (p for trend < 0.001). AF was associated with an increased risk of both early- and late-onset dementia, independent of clinical stroke.
