Living with young-onset dementia in the family – a mixed method study

Abstract

Background: Studies on disease-related obstructions experienced in everyday life of younger people with dementia (YOD ≤ 65 years) and their families are encouraged.Aim: To explore how the family carers experience six predefined topics that influence the everyday life and needs of persons with YOD.

Method: A quantitative and a qualitative study including family carers of persons with young-onset Alzheimer’s dementia (AD) and frontotemporal dementia (FTD). Seventy-four informants responded to the Camberwell Assessment of Needs in the Elderly (CANE) and individual interviews were conducted with 13 informants.

Results: Family carers of persons with YOD reported few unmet needs in the CANE assessment. Needs related to behavior and close relationships were reported significantly more frequent (p < 0.1) in persons with FTD than in persons with AD. From the qualitative data, six main themes were emphasized: daily activities turned upside down, involuntary loss of previous social network, losing close relationship, but maintaining a friendship with the spouse, unpredictable behavior adds burdens to a changing life, health and life risks, and economic insecurity for future life and caring costs.

Conclusion: Whilst family carers quantitatively reported unmet needs, the individual interviews reported several major difficulties in everyday life.

A Confirmatory and an Exploratory Factor Analysis of the Cohen-Mansfield Agitation Inventory (CMAI) in a European Case Series of Patients with Dementia: Results from the RECage Study

Abstract

Abstract

Background: One of the most widely used instruments for assessing agitation in dementia patients is the Cohen-Mansfield Agitation Inventory (CMAI), nevertheless no global score has been proposed. The aim of this study is: (a) to conduct a confirmatory (CFA) and exploratory factor analysis (EFA) of CMAI on people with dementia and Psychological and Behavioral Symptoms (BPSD), and (b) to propose an alternative structure, based on clinical criteria including all CMAI items.

Methods: Confirmatory and exploratory factor analyses were carried out on the CMAI 29 items administered at baseline to 505 patients with dementia (PwD) and BPSD enrolled in the international observational RECage study.

Results: The three-factor structure has not been confirmed by the CFA, whilst the EFA was carried out respectively on 25 items disregarding 4 items with a prevalence ≤5% and then on 20 items disregarding 9 items with a prevalence ≤10%. The four-factor structure explaining 56% of the variance comprised Physically Aggressive behavior, Verbally Aggressive behavior, Physically non-aggressive behavior, and Physically and verbally aggressive behavior.

Conclusions: A new grouping of all items according to a clinical criterion is proposed, allowing for a more sensible evaluation of the symptoms leading to better differentiation.

Knowledge and motivation to adopt recommended health behaviours to reduce dementia risk among the elderly in Norway: a qualitative study

Abstract

Abstract

Objectives: Dementia is a major healthcare challenge; however, there is evidence that modifiable risk factors may contribute to reduce dementia risk. The aim of the study was to explore the knowledge and motivation for adopting recommended health behaviours among older adults in Norway.
Study design: The study has a qualitative, descriptive design.

Methods: Individual interviews were used for data collection. The study population comprised 15 participants, five men and 10 women, aged ≥73 years, recruited from a region in the centre of Norway. Interviews were analysed according to qualitative content analysis.

Results: Three categories were identified and presented as the main findings, as follows: (1) sufficient knowledge about risk reduction for dementia, including the media as the main source of information; (2) current prevention activities and motivation for risk reduction, including physical, social and cognitive activities and a healthy diet; and (3) motivation for prevention of dementia from a life-course perspective, including experience of health problems, desire to live independently and limited awareness of dementia risk factors in midlife.

Conclusions: To tailor information about the modifiable risk factors of dementia and develop preventive interventions, knowledge about motivating factors is essential. Promotion of healthy ageing is required in addition to addressing the fear of future illness and dependency.

The transition of care from farm-based daycare for people with dementia: The perspective of next of kin

Abstract

Abstract
Purpose
The aim of the present study was to explore the next of kin’s experiences with the transition for people with dementia from a farm-based daycare (FDC) to another service in the municipality.
Methods
The study has a qualitative, descriptive design. Eight semi-structured interviews with next of kin were conducted. The data were analysed in accordance with content analysis.
Results
Through the analysis three main categories were developed: (1) Bearing the burden, (2) Being in transition, and (3) Feeling supported. The transition period was highly stressful for next of kin due to the exacerbation of their relatives’ dementia symptoms. The next of kin focussed on optimizing the everyday lives of their relatives with dementia, even at the expense of their own well-being. Most participants experienced support from FDC, healthcare services and their informal network.
Conclusions
The study contributes important insights into the next of kin’s experiences. Good quality service, close dialog, information, and support between the different part in the transition process, can be useful for the further development of services with good quality and to reduce the negative effects of care on next of kin.

Demens og mild kognitiv svikt hos eldre personer i Trøndelag

Abstract

Bakgrunn
Antallet personer med demens forventes tredoblet innen 2050. Vi presenterer forekomsttall for demens og mild kognitiv svikt i Trondheim og viser hvordan vekting for frafall og bostatus påvirker forekomsttallene når vi sammenligner Trondheim med Nord-Trøndelag.
Materiale og metode
Personer i alderen 70 år og eldre i Trondheim ble invitert til å delta i helseundersøkelsen HUNT4 (den fjerde Helseundersøkelsen i Trøndelag) Trondheim 70+. Deltakerne ble intervjuet og gjennomgikk kognitiv testing. Et diagnoseteam satte diagnosene demens og mild kognitiv svikt. Frafallsvekter som justerte for utvalgsskjevheter, ble benyttet i sammenligningen av Trondheim og Nord-Trøndelag.
Resultater
Demensforekomsten i Trondheim ble estimert til 16,2 % for aldersgruppen 70 år og eldre etter vekting for skjevt frafall med henblikk på alder, kjønn, utdanning og andel sykehjemsbeboere. Ujustert demensforekomst var 21,0 % i Trondheim og 15,7 % i Nord-Trøndelag. Etter vekting ble forekomsten tilnærmet identisk i de to utvalgene.
Fortolkning
Å vekte for skjevt frafall har stor betydning for å få representative tall i forekomstundersøkelser av demens.
Hovedfunn
Forekomsten av demens og mild kognitiv svikt hos personer i alderen 70 år og eldre i Trondheim ble estimert til henholdsvis 16,2 % og 35,6 %.
Ujustert demensforekomst var 21,0 % for Trondheim og 15,7 % for Nord-Trøndelag, men etter vekting for skjevt frafall med hensyn til alder, kjønn, utdanning og sykehjem ble forekomsten tilnærmet identisk i de to utvalgene.

Development and acceptability of the person-centred observation and reflection tool for supporting staff and practice development in dementia care services

Abstract

Background: Observational tools can support the understanding of the complex needs of older people with dementia and aid delivery of person-centred care. However, existing tools are complex and resource intensive to use.

Objectives: To develop and evaluate the acceptability and feasibility of a low-resource, observational tool to support staff reflection and practice development.

Methods: Intervention development of the Person-Centred Observation and Reflection Tool (PORT) and acceptability and feasibility study, using surveys and focus groups in the UK, Norway and Spain.

Results: PORT was reported as easy, accessible and acceptable to use. The observation was identified as powerful for individual staff development and provided an evidence-based source for underpinning individualised care planning. Potential time challenges associated with implementation were identified.

Conclusion: Initial evaluation indicates PORT is an acceptable and feasible tool for use in health and social care settings for older people. Further research is needed on implementation models and the impacts of PORT use.

Implications for practice: PORT may be a useful tool to support individual staff development in care settings and person-centred care planning for people with dementia.

Shared genetic loci between Alzheimer’s disease and multiple sclerosis: Crossroads between neurodegeneration and immune system

Abstract

Background: Neuroinflammation is involved in the pathophysiology of Alzheimer’s disease (AD), including immune-linked genetic variants and molecular pathways, microglia and astrocytes. Multiple Sclerosis (MS) is a chronic, immune-mediated disease with genetic and environmental risk factors and neuropathological features. There are clinical and pathobiological similarities between AD and MS. Here, we investigated shared genetic susceptibility between AD and MS to identify putative pathological mechanisms shared between neurodegeneration and the immune system.

Methods: We analysed GWAS data for late-onset AD (N cases = 64,549, N controls = 634,442) and MS (N cases = 14,802, N controls = 26,703). Gaussian causal mixture modelling (MiXeR) was applied to characterise the genetic architecture and overlap between AD and MS. Local genetic correlation was investigated with Local Analysis of [co]Variant Association (LAVA). The conjunctional false discovery rate (conjFDR) framework was used to identify the specific shared genetic loci, for which functional annotation was conducted with FUMA and Open Targets.

Results: MiXeR analysis showed comparable polygenicities for AD and MS (approximately 1800 trait-influencing variants) and genetic overlap with 20% of shared trait-influencing variants despite negligible genetic correlation (rg = 0.03), suggesting mixed directions of genetic effects across shared variants. conjFDR analysis identified 16 shared genetic loci, with 8 having concordant direction of effects in AD and MS. Annotated genes in shared loci were enriched in molecular signalling pathways involved in inflammation and the structural organisation of neurons.

Conclusions: Despite low global genetic correlation, the current results provide evidence for polygenic overlap between AD and MS. The shared loci between AD and MS were enriched in pathways involved in inflammation and neurodegeneration, highlighting new opportunities for future investigation.

The role of plasma inflammatory markers in late-life depression and conversion to dementia: a 3-year follow-up study

Abstract

Late-life depression (LLD) has been linked to increased likelihood of subsequent dementia, although mechanisms responsible for this association remain largely unknown. One feature frequently observed in both LLD and dementia is elevated levels of plasma inflammatory markers. PRODE (Prognosis of Depression in the Elderly) is a prospective naturalistic study of patients with LLD (N=152; aged 60+). Patients were followed up for 3 years; follow-up data was available for 138 patients, and 36 (26.1%) developed dementia by year 3. Plasma inflammatory markers data were available for 136 patients at baseline for the following range of cytokines and chemokines: IL-1β, IL-1ra, IL-6, IL-10, IL-17a, IL-18, IL-33, TNFα, CD40L, IFN-γ, CCL-2 and CCL-4. Levels of plasma inflammatory markers were compared between 136 LLD patients and healthy controls (n=103), using first multiple linear regression (inflammatory markers as outcome) with stepwise adjustment, and then binary logistic regression with depression status (LLD vs controls) as outcome. Further, we explored whether inflammatory markers and clinical characteristics of LLD (age of onset, course) predicted progression from LLD to dementia using Cox regression. Levels of IL-1ra, IFN-γ, CCL-2, CCL-4 and IL-17a were significantly higher in LLD patients compared to controls. However, none of the inflammatory markers predicted progression from LLD to dementia. Among clinical features, only poor response to treatment significantly predicted higher risk of progression to dementia. In summary, this study replicated previous findings of an increase in inflammatory markers in LLD but did not find evidence they had increased risk of developing future dementia.

The Association between Coffee and Tea Consumption at Midlife and Risk of Dementia Later in Life: The HUNT Study

Abstract

Background: Studies exploring the possible protective effect of coffee and tea consumption on dementia have shown inconsistent results so far. We aimed to investigate whether consumption of tea and different types of coffee at midlife are associated with dementia later in life and whether sex or ApoE4 influence such association.
Methods: We included 7381 participants from the Norwegian HUNT Study. Self-reported questionnaires assessed daily consumption of coffee and tea at baseline. After 22 years, individuals 70 years or older were screened for cognitive impairment.
Results: General coffee consumption and tea consumption was not associated with dementia risk. Compared to daily consumption of 0–1 cups of coffee, daily consumption of ≥8 cups of boiled coffee was associated with increased dementia risk in women (OR: 1.83, 95% CI: 1.10–3.04, p-value for trend = 0.03) and daily consumption of 4–5 cups of other types of coffee was associated with a decrease in dementia risk in men (OR: 0.48, 95% CI: 0.32–0.72, p-value for trend = 0.05). Furthermore, the association between boiled coffee and increased dementia risk was only found in ApoE4 non-carriers. Differences by sex or ApoE4 carrier status were not supported by strong statistical evidence for interaction. Tea consumption was not associated with dementia risk.
Conclusion: type of coffee may play a role in the direction of the association between coffee-drinking habits and dementia later in life.
