Self-reported sleep fragmentation and sleep duration and their association with cognitive function in PROTECT, a large digital community-based cohort of people over 50.

OBJECTIVE: Sleep is vital for normal cognitive function in daily life, but is commonly disrupted in older adults. Poor sleep can be detrimental to mental and physical health, including cognitive function. This study assessed the association between self-reported short (<6 h) and long (>9 h) sleep duration and sleep fragmentation (3≥ nightly awakenings) in cognitive function. METHODS: Cross-sectional data from 8508 individuals enroled in the PROTECT study aged 50 and above formed the basis of the univariate linear regression analysis conducted on four cognitive outcomes assessing visuospatial episodic memory (VSEM), spatial working memory, verbal working memory (VWM), and verbal reasoning (VR). RESULTS: Short (ß = -0.153, 95% CI [-0.258, -0.048], p = 0.004) and long sleep duration (ß = -0.459, 95% CI [-0.826, -0.091], p = 0.014) were significantly associated with poorer cognitive performance in VWM. Long sleep duration (ß = -2.986, 95% CI [-5.453, -0.518], p = 0.018) was associated with impaired VR. Short sleep (ß = -0.133, 95% CI [-0.196, -0.069], p = <0.001) and sleep fragmentation (ß = -0.043, 95% CI [-0.085, -0.001], p = 0.043) were associated with reduced VSEM. These associations remained significant when including other established risk factors for dementia and cognitive decline (e.g., depression, hypertension). CONCLUSIONS: Our findings suggest that short and long sleep durations and fragmented sleep, may be risk factors for a decline in cognitive processes such as working memory, VR and episodic memory thus might be potential targets for interventions to maintain cognitive health in ageing.

A data-driven examination of apathy and depressive symptoms in dementia with independent replication.

Apathy is one of the most common neuropsychiatric symptoms (NPS) and is associated with poor clinical outcomes. Research that helps define the apathy phenotype is urgently needed, particularly for clinical and biomarker studies. We used latent class analysis (LCA) with two independent cohorts to understand how apathy and depression symptoms co-occur statistically. We further explored the relationship between latent class membership, demographics, and the presence of other NPS. The LCA identified a four-class solution (no symptoms, apathy, depression, and combined apathy/depression), reproducible over both cohorts, providing robust support for an apathy syndrome distinct from depression and confirming that an apathy/depression syndrome exists, supported by the model fit test with the four-class solution scores evidencing better fitting (Bayesian information criterion adjusted and entropy R 2). Using a data-driven method, we show distinct and statistically meaningful co-occurrence of apathy and depressive symptoms. There was evidence that these classes have different clinical associations, which may help inform diagnostic categories for research studies and clinical practice. Highlights: We found four classes: no symptoms, apathy, depression and apathy/depression.Apathy conferred a higher probability for agitation.Apathy diagnostic criteria should include accompanying neuropsychiatric symptoms.

Healthcare utilisation, physical activity and mental health during COVID-19 lockdown: an interrupted time-series analysis of older adults in England.

COVID-19 measures which reduce interpersonal contact may be effective in containing the transmission, but their impacts on peoples' well-being and daily lives overtime remain unclear. Older adults are more vulnerable to both the virus and social isolation. It is therefore imperative to understand how they were affected during this period. Major concerns arising from the pandemic cover the aspects of mental health, healthcare utilisation and individual behavioural changes. Complementing the existing before-and-after analyses, we explore the impacts of easing and re-introducing COVID-19 measures by using a time-series data in England. The data was collected between May and November 2020 from the monthly surveys of the Platform for Research Online to Investigate Genetics and Cognition in Aging (PROTECT). Chi-squared analysis and interrupted time-series analysis were conducted to examine impacts of easing and re-introducing COVID-19 measures. Overall, mental health improves overtime but at a decreasing rate. The use of telephone/video consultations with a doctor or health professional presented a decreasing trend during the pandemic, whilst that of in-person consultation was increasing overtime. We observed significant variations in the time trends of mental health measures, healthcare utilisation and physical activity following the ease but not the re-introduction of COVID-19 measures. Future research is required to understand if these asymmetric impacts were driven by adaption of the people or stringency of the measures.

Awareness of age-related changes in Norwegian individuals 50+. Short form questionnaire validation.

Background: A questionnaire assessing awareness of positive and negative age-related changes (AARC gains and losses) was developed in the US and Germany, and validated for the UK and Brazilian populations. In this study, we validated the short-form measure (AARC-10 SF) in the Norwegian population aged 50 and over. In addition, the relationship between cognitive variables and AARC was examined. Methods: Cross-sectional analyses of data from 1,510 participants in the ongoing online PROTECT Norge study were used to explore and confirm the two-factor structure of AARC gains and AARC losses; reliability; measurement invariance across different population groups defined by sex, education level, employment, and in middle age, early old age, and advanced old age. We explored the relationship between AARC and demographic variables (defined in the same way as the population groups). Results: We confirmed the two-factor structure (gains and losses) of the Norwegian translation of the AARC-10 SF. We did not find mutual correlations between related items in gains and losses, except for the physical health item from the gains dimension, which was positively correlated with all items of the losses dimension. Age, sex, marital status, employment, and university education predicted AARC gains and losses. Conclusion: The Norwegian translation of the AARC-10 SF captures individuals' positive and negative self-perceptions of age-related changes in their mental, physical, and cognitive health.

Healthcare utilisation and physical activities for older adults with comorbidities in the UK during COVID-19.

A major concern with COVID-19 was the impact it would have on individual health, the routine use of healthcare services, and physical activities, especially for older adults with comorbidities. To address this, we studied the association between these variables for older adults during the pandemic. To explore what policy instruments might be effective in mitigating the negative impacts, we investigated the effects of a shielding notice for those identified as vulnerable by the government and social media given it has been an important source for disseminating information of COVID-19. We employed a UK sample with 3,807 participants aged ≥50 from an online survey administered during May and June 2020. Based on numbers of comorbidities, we separated the sample into a higher comorbidity group with those in the upper quartile of the sample (n = 829) and a lower comorbidity group with the remainder (n = 2,978). Statistical methods include chi-squared analyses and cross-sectional regressions. We found that individuals with higher comorbidities were more likely to have poorer self-reported health and mental health and to receive a shielding notice from the government compared to those without (p < 0.05). Decreases in physical activities were associated with poorer self-reported health and the increases were associated with better self-reported health; on the other hand, the decreases were associated with poorer mental health, but the increases did not link to better mental health. Examination of the effects of policy instruments shows that a shielding notice was positively associated with primary care use. The notice generated greater reliance on telephone/video consultations compared to in-person consultations, but the impacts were less strong for people with higher comorbidities. Frequent use of social media raised the probability of increasing physical activities and reduced that of decreasing physical activities, implying social media being an effective tool in promoting physical activities during the lockdown and subsequent restrictions.

Investigating the effects of impairment in non-verbal communication on neuropsychiatric symptoms and quality of life of people living with dementia.

INTRODUCTION: People living with dementia in nursing homes have complex needs; impairments in cognition, communication, and daily function; neuropsychiatric symptoms (NPS); and poor quality of life (QoL). The current study examines impairments in non-verbal communication as a potential driver of NPS and QoL. METHODS: One hundred nursing home residents with dementia were assessed using the Emory Dyssemia Index (EDI), Neuropsychiatric Inventory Nursing Home version (NPI-NH), Quality of Life in Alzheimer's Disease (QoL-AD) at baseline, 12-, and 24-week follow-up. RESULTS: The quantile regression (0.5) model indicated that impairment of non-verbal communication was independently associated with the severity of NPS (P = .001) and proxy reported QoL (P < .05), levels of agitation (P < .05), and professional caregiver burden (P < .05). DISCUSSION: These results highlight a novel potential approach to improve NPS and QoL using retained elements of non-verbal communication, particularly for people with severe dementia.

The association between aspects of carer distress and time until nursing home admission in persons with Alzheimer's disease and dementia with Lewy bodies.

OBJECTIVE: The aim of this study was to explore the association between specific aspects of carer distress and time until nursing home admission (NHA) in people with mild dementia. DESIGN: Prospective cohort study. SETTING: Participants were recruited from the Dementia Study of Western Norway (DemVest). PARTICIPANTS: This study included 107 participants admitted to a nursing home who were diagnosed with Alzheimer's disease (AD, n = 64) and dementia with Lewy bodies (DLB, n = 43) and their primary carers. MEASUREMENTS: The Relative Stress Scale (RSS) was used to assess the level of reported distress in carers. Adjusted partial least square (PLS) prediction analysis of baseline items of the RSS was used to study the associations between individual items of the RSS and time until NHA. RESULTS: Carer distress is an important contributor to early NHA, explaining 19.3% of the total variance of time until NHA in the model without covariates. In the adjusted PLS model, the most important RSS predictors of time until NHA were feeling frustrated (estimate = -137; CI, -209, -64.5), having limitations on social life (estimate = -118; CI, -172, -64), not being able to get away on vacation (estimate -116; CI, -158.3, -73.7), and feeling unable to cope with the situation (estimate = -63; CI, -122.6, -3.4). CONCLUSIONS: Preservation of the informal care capacity represents important steps for improving the management of resources in dementia care. This study identifies aspects of carer distress associated with a shorter time until NHA. Looking beyond the sum score of the RSS helps promote the development of flexible and tailored interventions and perhaps delay NHA.

Loneliness, physical activity, and mental health during COVID-19: a longitudinal analysis of depression and anxiety in adults over the age of 50 between 2015 and 2020.

OBJECTIVE: Loneliness and physical activity are important targets for research into the impact of COVID-19 because they have established links with mental health, could be exacerbated by social distancing policies, and are potentially modifiable. In this study, we aimed to identify whether loneliness and physical activity were associated with worse mental health during a period of mandatory social distancing in the UK. DESIGN: Population-based observational cohort study. SETTING: Mental health data collected online during COVID-19 from an existing sample of adults aged 50 and over taking part in a longitudinal study of aging. All had comparable annual data collected between 2015 and 2019. PARTICIPANTS: Three-thousand two-hundred and eighty-one participants aged 50 and over. MEASUREMENTS: Trajectories of depression (measured by PHQ-9) and anxiety (measured by GAD-7) between 2015 and 2020 were analyzed with respect to loneliness, physical activity levels, and a number of socioeconomic and demographic characteristics using zero-inflated negative binomial regression. RESULTS: In 2020, PHQ-9 score for loneliness, adjusted for covariates, was 3.23 (95% CI: 3.01-3.44), an increase of around 1 point on all previous years in this group and 2 points higher than people not rated lonely, whose score did not change in 2020 (1.22, 95% CI: 1.12-1.32). PHQ-9 was 2.60 (95% CI: 2.43-2.78) in people with decreased physical activity, an increase of .5 on previous years. In contrast, PHQ-9 in 2020 for people whose physical activity had not decreased was 1.66, 95% CI: 1.56-1.75, similar to previous years. A similar relationship was observed for GAD-7 though the absolute burden of symptoms lower. CONCLUSION: After accounting for pre-COVID-19 trends, we show that experiencing loneliness and decreased physical activity are risk factors for worsening mental health during the pandemic. Our findings highlight the need to examine policies which target these potentially modifiable risk factors.

Health promotion intervention for people with early-stage dementia: A quasi-experimental study.

INTRODUCTION: With the limited advancements in medical treatment, there is a growing need for supporting people with early-stage dementia adjust to their diagnosis and improve their quality of life. This study aimed to investigate the effects of a 12-week health promotion course for people with early-stage dementia. METHODS: Quasi-experimental, single group, pretest-posttest design. A total of 108 persons with dementia participated in this study, and for each participant, a carer was interviewed. The 12-week health promotion intervention consisted of 2-hr sessions at weekly intervals. Outcome measures were cognition, measured by Mini-Mental State Examination, personal, and instrumental activities of daily living (P-ADL and I-ADL), measured by Lawton and Brody's Physical Self-Maintenance Scale and Instrumental Activities of Daily Living Scale, self-rated health, measured by the European Quality of life Visual Analogue Scale, depressive symptoms, measured by the Cornell Scale for Depression in Dementia, and neuropsychiatric symptoms, measured by The Neuropsychiatric Inventory. Assessments were conducted at baseline and at follow-up 1-2 months postintervention. RESULTS: The results demonstrate a small but statistically significant improvement in depressive symptoms (p = .015) and in self-rated health (p = .031). The results also demonstrated a small statistically significant decline in the participants' I-ADL (p = .007). The participants' cognitive function, P-ADL, and neuropsychiatric symptoms were stable during the 4-month follow-up. CONCLUSION: This study demonstrates promising results with regard to the benefit of attending a 12-week health promotion intervention in promoting health and well-being in people with early-stage dementia. With the majority of participants with early-stage dementia living at home without any healthcare services in a vulnerable stage of the condition, this study makes an important contribution to highlighting the need for, and benefit of, educational approaches for this population.

Self-management and HeAlth Promotion in Early-stage dementia with e-learning for carers (SHAPE): study protocol for a multi-centre randomised controlled trial.

BACKGROUND: With an increasing number of people with dementia worldwide and limited advancement in medical treatments, the call for new and cost-effective approaches is crucial. The utility of self-management has been proven in certain chronic conditions. However, very little work has been undertaken regarding self-management in people with dementia. METHODS: The SHAPE trial will include 372 people with mild to moderate dementia to evaluate the effectiveness and cost-effectiveness of an educational programme combining approaches of self-management, health promotion, and e-learning for care partners. The study is a multi-site, single-randomised, controlled, single-blinded trial with parallel arms. The intervention arm is compared with treatment as usual. The intervention comprises a 10-week course delivered as group sessions for the participants with dementia. The sessions are designed to develop self-management skills and to provide information on the nature of the condition and the development of healthy behaviours in a supportive learning environment. An e-learning course will be provided for care partners which covers similar and complementary material to that discussed in the group sessions for the participant with dementia. DISCUSSION: This trial will explore the effect of the SHAPE group intervention on people with mild to moderate dementia in terms of self-efficacy and improvement in key health and mental health outcomes and cost-effectiveness, along with carer stress and knowledge of dementia. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04286139, registered prospectively February 26, 2020, https://clinicaltrials.gov/ct2/show/NCT04286139.

Health Care Personnel's Perspective on Potential Electronic Health Interventions to Prevent Hospitalizations for Older Persons Receiving Community Care: Qualitative Study.

BACKGROUND: The use of electronic health (eHealth) interventions is suggested to help monitor and treat degenerative and chronic diseases through the use of sensors, alarms, and reminders and can potentially prevent hospitalizations for home-dwelling older persons receiving community care. It is increasingly recognized that the health care personnel's acceptance of a technological application remains a key challenge in adopting an intervention, thus interventions must be perceived to be useful and fit for purpose by the actual users. OBJECTIVE: The aim of this study was to identify and explore the perspectives of managers and health care personnel in community care regarding the use of eHealth interventions in terms of prevention of hospitalizations for home-dwelling older persons receiving community care. METHODS: A case study with a qualitative approach was carried out in community care in a Norwegian municipality, comprising individual interviews and focus group interviews. A total of 5 individual interviews and 2 focus group interviews (n=12) were undertaken to provide the health care personnel's and managers' perspective regarding the use of eHealth interventions, which could potentially prevent hospitalizations for home-dwelling older persons receiving community care. Data were analyzed by way of systematic text condensation, as described by Malterud. RESULTS: The data analysis of focus group interviews and individual interviews resulted in 2 categories: potential technological applications and potential patient groups. Discussions in the focus groups generated several suggestions and wishes related to technical applications that they could make use of in their day-to-day practice. The health care personnel warranted tools and measures to enhance and document their clinical observations in contact with patients. They also identified patient groups, such as patients with chronic obstructive pulmonary disease or dehydration or urinary tract infections, for whom hospitalizations could potentially have been prevented. CONCLUSIONS: We have shown that the health care personnel in community care warrant various technological applications that have the potential to improve quality of care and resource utilization in the studied municipality. We have identified needs and important matters in practice, which are paramount for acceptance and adoption of an intervention in community care.

"We should see her like part of the team": an investigation into care home staff's experiences of being part of an RCT of a complex psychosocial intervention.

Objectives: To contribute to improvements in the design and delivery of intervention research in care homes by adopting a collaborative approach that listens to the experiences of care home staff who had participated in a clinical trial aimed at optimising and evaluating a psychosocial intervention package for people with dementia.Methods: Qualitative study involving focus group discussions (FGDs) involving 41 staff across 6 care homes with the UK. Inductive thematic analysis was used to identify themes and interpret the data.Results: Three overarching themes emerged as influential: Recognising preparedness; working together and learning more than expected. The findings highlighted the need to be attentive in addressing staff expectations, the value of sustained relationships and recognition of good practice. The FGDs also identified areas of unanticipated learning that staff and managers adopted.Conclusions: The FGDs showed the importance of considering the overall experience of care home staff who are involved in research and the importance of valuing the skills and experience they hold through positive affirmation. There are often unanticipated consequences of research involvement both on staff practice and on relationships which if promoted could help sustain effective ways of working together.

Nutritional Interventions for Persons With Early-Stage Dementia or Alzheimer's Disease: An Integrative Review.

Persons with Alzheimer's disease and related dementias (ADRD) are at particular risk of malnutrition and weight loss. Clinical research concerning the role and impact of nutritional intervention in early-stage ADRD, specifically on cognition and key symptoms such as behavior, is less straightforward. Thus, an integrative review was conducted to examine the literature pertaining to nutritional interventions for persons with ADRD and to make recommendations for priority areas for future research and practice. Findings from the studies reviewed highlight multiple potential opportunities for improving nutritional status and support for persons with ADRD living in the community. Despite the small amount of evidence, the six studies identified in the current review suggest a broad benefit may be conferred through educational approaches and nutritional supplementation.

The association between specific neuropsychiatric disturbances in people with Alzheimer's disease and dementia with Lewy bodies and carer distress.

OBJECTIVE: Neuropsychiatric symptoms (NPSs) are identified as important care-recipient variables in terms of the impact on carer distress. The aim of this study was to determine whether specific neuropsychiatric disturbances in people with Alzheimer disease (AD) and dementia with Lewy bodies (DLB) differentially impact carer distress. METHODS: This was a cross-sectional study of people diagnosed with AD and DLB and their primary carers. The Relatives' Stress Scale (RSS) was used to assess the level of reported distress in carers, and the Neuropsychiatric Inventory (NPI) was used to assess NPSs. The effect of NPSs on carer distress was analyzed using correlation analysis and partial least squares regression. RESULTS: This study included 159 participants diagnosed with AD (n = 97) and DLB (n = 62) and their primary carers (spouses and adult children). The majority of people diagnosed with dementia were women (64.2%), with a mean age of 75.9 years (SD, 7.4) and a mean Mini-Mental State Examination (MMSE) score of 23.5 (SD, 2.9). The main analysis identified apathy as the most important NPS contributing to carer distress. Compared with AD, the explained variance in the DLB group was higher (r2  = 37.3 vs r2  = 53.7). In addition, more NPSs were considered clinically important in the DLB group. CONCLUSION: The findings of this study identify apathy as the most important NPS contributing to carer distress among carers of people with AD and DLB. These findings help us identify the support needs of families dealing with dementia.

What influences the sustainability of an effective psychosocial intervention for people with dementia living in care homes? A 9 to 12-month follow-up of the perceptions of staff in care homes involved in the WHELD randomised controlled trail.

OBJECTIVES: The study aims to understand the factors that care home staff felt enabled or hindered them in continuing to use the well-being and health for people with dementia (WHELD) psychosocial approach in their care home and investigate whether there was sustained activity 9 to 12 months after the study ended. METHODS: This qualitative study is part of a wider clinical trial, which demonstrated effectiveness of a psychosocial intervention on quality of life outcomes and neuropsychiatric symptoms for residents. Forty-seven care home staff within nine care homes in the United Kingdom participated in focus groups, between 9 and 12 months after the intervention had finished. Inductive thematic analysis was used to identify themes and interpret the data. RESULTS: The findings highlighted that staff continued to use a range of activities and processes acquired through the research intervention, after the study had ended. Three overarching themes were identified as influential: "recognising the value" of the approach for residents and staff, "being well practiced" with sufficient support and opportunity to consolidate skills prior to the withdrawal of the researchers, and "taking ownership of the approach" to incorporate it as usual care. CONCLUSIONS: The WHELD approach can be sustained where the value of the approach is recognised, and sufficient support is provided during initial implementation for staff to build skills and confidence for it to become routine care. Further follow-up is required to understand longer term use and the impact for residents.

The Effect of a Multicomponent Intervention on Quality of Life in Residents of Nursing Homes: A Randomized Controlled Trial (COSMOS).

OBJECTIVES: To investigate if the multicomponent intervention of the COSMOS trial, combining communication, systematic pain management, medication review, and activities, improved quality of life (QoL) in nursing home patients with complex needs. DESIGN: Multicenter, cluster-randomized, single-blinded, controlled trial. SETTING: Thirty-three nursing homes with 67 units (clusters) from 8 Norwegian municipalities. PARTICIPANTS: Seven hundred twenty-three patients with and without dementia (≥65 years) were cluster randomized to usual care or intervention in which health care staff received standardized education and on-site training for 4 months with follow-up at month 9. MEASUREMENTS: Primary outcome was change in QoL as measured by QUALIDEM (QoL dementia scale); QUALID (QoL late-stage dementia scale), and EQ-VAS (European QoL-visual analog scale) from baseline to month 4. Secondary outcomes were activities of daily living (ADL), total medication, staff distress, and clinical global impressions of change (CGIC). RESULTS: During the active intervention, all 3 QoL measures worsened, 2 significantly (QUALID P = .04; QUALIDEM P = .002). However, follow-up analysis from month 4 to 9 showed an intervention effect for EQ-VAS (P = .003) and QUALIDEM total score (P = .01; care relationship P = .02; positive affect P = .04, social relations P = .01). The secondary outcomes of ADL function, reduction of medication (including psychotropics) and staff distress, improved significantly from baseline to month 4. Intervention effects were also demonstrated for CGIC at month 4 (P = .023) and 9 (P = .009), mainly because of deterioration in the control group. CONCLUSION AND IMPLICATIONS: Temporarily, the QoL decreased in the intervention group, leading to our hypothesis that health care staff may be overwhelmed by the work-intensive COSMOS intervention period. However, the decrease reversed significantly during follow-up, indicating a potential learning effect. Further, the intervention group improved in ADL function and received less medication, and staff reported less distress and judged COSMOS as able to bring about clinically relevant change. This suggests that nonpharmacologic multicomponent interventions require long follow-up to ensure uptake and beneficial effects.

Porcelain for All - a nursing home study.

PURPOSE: The Porcelain for All project was an initiative by Figgjo AS, a porcelain factory in Norway, which needed more research on different coloured porcelains. The paper aims to discuss this issue. DESIGN/METHODOLOGY/APPROACH: The study aimed to gain new knowledge about how different décor and dinner plate colours can positively influence dementia sufferer food intake and appetite. The intervention period lasted three weeks. Four days were randomly picked during that period. Each plate was photographed before and after the resident had eaten, researchers conducted observations during mealtimes. Two CurroCus® group interviews were used to collect additional empirical data. In total, 12 dementia sufferers (five females) between 65 and 85 years were observed during dinnertime. FINDINGS: Plates with a white well, yellow lip and red rim seemed to be preferred regarding food intake. Three main categories were noted from the observations and group interviews: mealtime dignity, porcelain design and appetite. RESEARCH LIMITATIONS/IMPLICATIONS: Future research could incorporate well-being in people with dementia regarding food weight, testing different meal room environments, user involvement, food presentation and should include more nursing homes and residents. PRACTICAL IMPLICATIONS: This study only encompasses a small sample (12 residents), all diagnosed with dementia. SOCIAL IMPLICATIONS: Outcomes may help to prevent undernutrition among elderly people. ORIGINALITY/VALUE: Combined coloured porcelain, food intake and residents with dementia is scarcely investigated.

Characteristics and predictors for hospitalizations of home-dwelling older persons receiving community care: a cohort study from Norway.

BACKGROUND: Older persons are substantial consumers of both hospital- and community care, and there are discussions regarding the potential for preventing hospitalizations through high quality community care. The present study report prevalence and factors associated with admissions to hospital for community-dwelling older persons (> 67 years of age), receiving community care in a Norwegian municipality. METHODS: This was a cohort study of 1531 home-dwelling persons aged ≥67 years, receiving community care. We retrospectively scrutinized admissions to hospital for the study cohort over a one-year period in 2013. The frequency of admissions was evaluated with regard to association with age (age groups 67-79 years, 80-89 years and ≥ 90 year) and gender. The hospital admission incidence was calculated by dividing the number of admissions by the number of individuals included in the study cohort, stratified by age and gender. The association between age and gender as potential predictors and hospitalization (outcome) was first examined in univariate analyses followed by multinomial regression analyses in order to investigate the associations between age and gender with different causes of hospitalization. RESULTS: We identified a total of 1457 admissions, represented by 739 unique individuals, of which 64% were women, and an estimated mean age of 83 years. Mean admission rate was 2 admissions per person-year (95% confidence interval (CI): 1.89-2.11). The admission rate varied with age, and hospital incidents rates were higher for men in all age groups. The overall median length of stay was 4 days. The most common reason for hospitalization was the need for further medical assessment (23%). We found associations between increasing age and hospitalizations due to physical general decline, and associations between male gender and hospitalizations due to infections (e.g., airways infections, urinary tract infections). CONCLUSIONS: We found the main reasons for hospitalizations to be related to falls, infections and general decline/pain/unspecified dyspnea. Men were especially at risk for hospitalization as they age. Our study have identified some clinically relevant factors that are vital in understanding what health care personnel in community care need to be especially aware of in order to prevent hospitalizations for this population.

Patterns of carer distress over time in mild dementia.

OBJECTIVE: To study the level of carer reported distress in mild dementia, over a 3-year period. METHODS: This study is part of the Norwegian DemVest-study and utilises data from carers of people with mild dementia (n = 223). Those diagnosed with dementia with Lewy bodies (DLB, n = 63) and Alzheimer's disease (AD, n = 97) were included together with other dementia types (n = 63). The Relatives' Stress Scale was used to assess the level of reported distress in carers. Descriptive and a linear mixed effects models including diagnosis, time, and the interaction between time and diagnosis were performed. RESULTS: Carer distress in mild dementia increased significantly over time (P = 0.011), particularly from baseline until 2 (P = 0.001) years follow-up. Carer distress in people caring for those with AD increased significantly, from baseline until 2 (P = 0.047) and 3 (P = 0.019) years follow-up. Distress in carers of people with DLB was high at baseline and remained relatively stable across the 3-year period. However, admission to a nursing home during the first year of follow-up was associated with a significantly lower reported carer distress in those caring for a person with DLB (P = 0.002), compared with those caring for a person with DLB living at home. CONCLUSION: Being a carer to a person with mild dementia is associated with increasing distress. However, the burden of distress changes with the diagnosis, time, and situation, which highlights the dynamic nature of the caring role. Findings have important implications for health services for people diagnosed with mild dementia and their carers.
