Relationship of care staff attitudes with social well-being and challenging behavior of nursing home residents with dementia: a cross sectional study.

Objectives: This study investigates the relationship between attitudes of care staff and social well-being and challenging behavior of residents in long-term dementia care. Methods: The study was based on a cross-sectional design using questionnaires. Care staff members (N = 291) of 15 long-term care facilities in the Netherlands completed the Approaches to Dementia Questionnaire. Additionally, the primary professional caregiver of each participating resident (N = 239) completed an observational questionnaire regarding that resident's behavior, which contained the scale for Social Wellbeing Of Nursing home residents and the Cohen-Mansfield Agitation Inventory. Data were analyzed using multilevel analyses, taking characteristics of residents into account. Results: Attitudes of care staff towards residents with dementia differed between facilities. Further, residents experienced more social well-being and displayed less challenging behavior in facilities where care staff had more hopeful attitudes. Conclusion: This study demonstrates a relationship between attitudes of care staff and resident well-being. The results indicate that it is important to address attitudes towards residents with dementia in the education of (future) care staff. Care processes may also be improved by focusing on the attitudes of care staff. In this way, the well-being of residents with dementia can potentially be improved as well.

Cognitive reserve as a moderator of the negative association between mood and cognition: evidence from a population-representative cohort.

BACKGROUND: Cognitive reserve (CR) has been associated with better cognitive function and lower risk of depression in older people, yet it remains unclear whether CR moderates the association between mood and cognition. This study aimed to investigate whether a comprehensive indicator of CR, including education, occupation and engagement in cognitive and social activities, acts as a moderator of this association. METHODS: This was a cross-sectional study utilising baseline data from the Cognitive Function and Ageing Study II (CFAS II), a large population-based cohort of people aged 65+ in England. Complete data on the measures of CR, mood and cognition were available for 6565 dementia-free individuals. Linear regression models were used to investigate the potential modifying effect of CR on the association between cognition and mood with adjustment for age, sex and missing data. RESULTS: Levels of CR did moderate the negative association between mood and cognition; the difference in cognition between those with and without a clinical level mood disorder was significantly smaller in the middle (-2.28; 95% confidence interval (CI) -3.65 to -0.90) and higher (-1.30; 95% CI -2.46 to -0.15) CR groups compared with the lower CR group (-4.01; 95% CI -5.53 to -2.49). The individual components of CR did not significantly moderate the negative association between mood and cognition. CONCLUSION: These results demonstrate that CR, indexed by a composite score based on multiple indicators, can moderate the negative association between lowered mood and cognition, emphasising the importance of continuing to build CR across the lifespan in order to maintain cognitive health.

Access to community care for people with dementia and their informal carers : Case vignettes for a European comparison of structures and common pathways to formal care.

BACKGROUND: People with dementia and their informal carers often do not receive appropriate professional support or it is not received at the right time. OBJECTIVES: Description and comparison of common pathways to formal community dementia care in eight European countries as a part of the transnational Actifcare project. MATERIALS AND METHODS: The German team was responsible for creating an individual case scenario as a starting point. The research teams in Ireland, Italy, the Netherlands, Norway, Portugal, Sweden, and the United Kingdom were then asked to describe a common pathway to formal dementia care by writing their own vignette using the provided individual case scenario. RESULTS: A transnational qualitative content analysis was used to identify the following categories as being the most important: involved professionals, dementia-specific and team-based approaches, proactive roles, and financial aspects. General practitioners (GPs) are described as being the most important profession supporting the access to formal care in all the involved countries. In some countries other professionals take over responsibility for the access procedure. Dementia-specific approaches are rarely part of standard care; team-based approaches have differing significances in each of the countries. Informal carers are mainly proactive in seeking formal care. The Nordic countries demonstrate how financial support enhances access to the professional system. CONCLUSION: Enhanced cooperation between GPs and other professions might optimize access to formal dementia care. Team-based approaches focusing on dementia care should be developed further. Informal carers should be supported and relieved in their role. Financial barriers remain which should be further investigated and reduced.

An investigation into the association between nutritional status and quality of life in older people admitted to hospital.

BACKGROUND: Malnutrition is prevalent in acute hospitals and malnourished patients have an increased risk of morbidity and mortality. Studies of malnutrition and quality of life (QoL) are generally limited by both the nutritional and QoL assessment methods employed. The present study aimed to evaluate the relationship between malnutrition, as assessed using a range of nutritional assessment methods, and QoL, as measured by EuroQol-5D-3L and Short-Form (SF)-36 questionnaires. METHODS: The study comprised a prospective cross-sectional study of malnutrition and QoL in 149 inpatients aged 65-99 years. Exclusion criteria were: terminal illness, active malignancy, lack of capacity to consent and severe communication difficulties. Spearman's rank correlation coefficient was used to test the association between QoL indices and nutritional markers. QoL scores for those scoring above and below thresholds for nutritional risk were compared. Regression models were created to identify nutritional indices contributing to the variability of QoL. RESULTS: There were significant associations between QoL scores and the Mini Nutritional Assessment (MNA)-SF. Clear differences were evident between malnourished and well-nourished patients (on the MNA-SF), those with low and normal arm muscle circumference and those with good and poor physical function. Regression analysis showed that nutritional scores and functional status made independent contributions to the prediction of QoL. The effect on food intake, mobility and psychological stress/acute disease also had a significant influence. CONCLUSIONS: Malnutrition risk is linked to a poorer QoL in older people on admission to hospital. Functional status and eating-related factors are major influencers on QoL in this group. These findings reinforce the role of nutrition as a priority with respect to achieving improvements in QoL.

Particle Track, X-ray, Thermal, and Mass Spectrometric Studies of Lunar Material.

Particle tracks in Apollo 11 samples are dominantly of cosmic ray and solar origin: primary galactic and solar flare particles, likely spallation recoil tracks, and possible solar-wind heavy particles. The energy spectrum of irongroup nuclei is inferred from track density gradients in surface layers, and a limit of << 10(-7) centimeter per year is deduced for the surface erosion rate. From cosmic ray tracks in rock and core samples it is clear that the lunar soil is stirred often during each few million years. X-rays reveal augite, anorthite, olivine, ilmenite, troilite, nonmeteoritic iron, and assorted glasses, but no major structural damage. Hydrogen, helium, and other gases in the fines are compatible with expected solar wind ratios.

Subjective memory complaints and awareness of memory functioning in mild cognitive impairment: a systematic review.

OBJECTIVES: Subjective memory complaint (SMC) is central to the diagnosis of mild cognitive impairment (MCI). People with MCI are at a higher risk of progressing to dementia, and research on SMC is contradictory in terms of the accuracy of SMC and its predictive role for future dementia. One possible reason for these contradictory findings is that the level of awareness of memory function may vary among people with MCI. This review examines whether the level of awareness of memory functioning varies amongst people classified as having MCI and whether there is support for the suggestion that the level of awareness in MCI predicts future progression to dementia. METHOD: Sixteen studies were identified which evaluate the awareness level in people classified as having MCI in either a clinical or research setting. In addition to the outcome of each study, the conceptualization of awareness, 'object' of awareness and methodology were also considered. RESULTS: There is evidence to show that the level of awareness in MCI does vary, and this may have implications for future progression to dementia. CONCLUSIONS: Given the increased risk of progression to dementia for those identified as having MCI, the role of awareness should be explored further with due consideration given to the conceptualization of awareness and the methodology employed. The finding of variability in awareness has implications for the use of SMC in the diagnostic criteria for MCI.

Reminiscence therapy for dementia.

BACKGROUND: Reminiscence Therapy (RT) has been defined as vocal or silent recall of events in a person's life, either alone, or with another person or group of people. It typically involves group meetings, at least once a week, in which participants are encouraged to talk about past events, often assisted by aids such as photos, music, objects and videos of the past. There is, often, little consistent application of psychological therapies in dementia services. A number of these 'therapies' were greeted with enthusiasm by health care practitioners in under stimulating care environments. They were expected to work miracles and their 'failure' to do this has led to their widespread disuse. A systematic review of the available evidence is important in order to identify the effectiveness of the different therapies. Subsequently, guidelines for their use can be made on a sound evidence base. OBJECTIVES: RT involves groups of elderly people talking of past events, assisted by aids such as videos, pictures and archives, as a means of communicating and reflecting upon their life experiences. The objective of the review is to assess the effects of RT for dementia. SEARCH STRATEGY: We searched the Cochrane Controlled Trials Register, MEDLINE, PSYCHLIT, EMBASE, OMNI, BIDS, Dissertation Abstracts International, SIGLE and reference lists of relevant articles up to 1998, and we contacted specialists in the field. We also searched relevant Internet sites and we hand searched Aging and Mental Health, the Gerontologist, Journal of Gerontology, Current Opinion in Psychiatry, Current Research in Britain: Social Sciences, British Psychological Society conference proceedings and Reminiscence database. SELECTION CRITERIA: Randomised controlled trials and quasi-randomised trials of RT for dementia in elderly people. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed trial quality. MAIN RESULTS: Two trials are included in the review, but only one trial with 15 participants had extractable data. The results were statistically non-significant for both cognition and behaviour. REVIEWER'S CONCLUSIONS: No firm conclusions could be reached regarding the effectiveness of RT for dementia. The review highlighted the urgent need for more systematic research in the area.

Cognitive rehabilitation and cognitive training for early-stage Alzheimer's disease and vascular dementia.

BACKGROUND: Memory problems are a defining feature of the early stages of Alzheimer's disease (AD) and vascular dementia. Cognitive training and cognitive rehabilitation are specific approaches designed to address everyday memory difficulties. OBJECTIVES: The main aim was to evaluate the effectiveness and impact of cognitive training and cognitive rehabilitation interventions aimed at improving memory functioning for people in the early stages of Alzheimer's disease or vascular dementia. The two types of intervention were considered separately. SEARCH STRATEGY: The CDCIG Specialized Register, which contains records from MEDLINE, EMBASE, CINAHL, PsycINFO and many other databases, was searched on 9 April 2003. SELECTION CRITERIA: RCTs comparing cognitive rehabilitation or cognitive training interventions with comparison conditions, and reporting outcomes for the person with dementia and/or the family caregiver, were considered for inclusion. DATA COLLECTION AND ANALYSIS: Six studies reporting cognitive training interventions were included. Statistical analyses were conducted to provide an indication of intervention effect sizes. Data from ordinal scales was treated as continuous, and a fixed effects model was applied in calculating weighted mean differences and 95% confidence intervals. No studies were found that reported a fully individualised cognitive rehabilitation approach. MAIN RESULTS: None of the six studies reporting cognitive training interventions demonstrated any statistically significant effects in any domain, although there were indications of some modest, non-significant effects in various domains of cognitive functioning. REVIEWER'S CONCLUSIONS: The present findings do not provide strong support for the use of cognitive training interventions for people with early-stage AD or vascular dementia, although these findings must be viewed with caution due to the limited number of RCTs available and to the methodological limitations identified, and further well-designed trials would help to provide more definitive evidence. Due to a complete absence of RCTs evaluating an individualised cognitive rehabilitation approach, It is not possible at present to draw conclusions about the efficacy of individualised cognitive rehabilitation interventions for people with early-stage dementia, and further research is required in this area.

Why do we assess the aged?

The relevance of assessment to the psychological management of elderly patients is outlined. Issues raised by Kendrick (1982) and Rabbitt (1982) are discussed in this context.

Automated cognitive assessment of elderly patients: a comparison of two types of response device.

Groups of 14 cognitively impaired elderly people were tested on two automated cognitive tests on several occasions. Patients registered their responses using either a touch-sensitive screen or a board with illuminated response buttons. The results indicate that the touch-sensitive screen is probably a more suitable response device than the button-board. Suggestions that it would prove disadvantageous to elderly patients were not supported, and its continued use is recommended.

Discovering the person with Alzheimer's disease: Cognitive, emotional and behavioural aspects.

The person-centred approach to dementia care emerges from a new emphasis on the experience of the person with dementia. The person is seen as attempting to manage and cope with their difficulties, through a variety of coping mechanisms. Some are able to seek to maximize their cognitive capacities, and there are a number of strategies now available to assist in this process. However, the emotional aspects merit increased attention, with more awareness needed of the range of powerful emotions that may be present, and of the possibility of therapeutic interventions to alleviate symptoms of anxiety and depression. Many of the difficult behaviours seen in dementia may be understood more fully with an appreciation of their emotional underpinning, in feelings of anger, fear, insecurity and hopelessness. The interaction between caregiver strain and challenging behaviour also merits further exploration. The person-centred approach has many implications for practice, as well as for research. The perspective of the person with dementia, and outcomes reflecting that perspective, must be represented in research studies in dementia care. Caregivers, whether family members or paid workers, require additional support in order to recognize the person's needs and to meet them in ways which enable the person's identity and full human value to be upheld.

Effect of family relationships on psychogeriatric patients.

Severe strain has been repeatedly reported in the families of psychogeriatric patients. Nevertheless, many families continue to provide a great deal of support, despite the undoubted burden involved. A retrospective study of short-term outcome in 60 psychogeriatric referrals demonstrated the importance of some aspects of the relationship between the patient and their key supporting relative. In the sample as a whole, and in functional patients, the extent to which a positive communication system existed was significant. In patients with dementia, poor outcome was related to the patient being less dependent and more dominant in their interaction with the relative. The implications of this study for intervention and future research are discussed.

Gender differences in carers of dementia sufferers.

Recent research shows that the demands of the caregiving role are experienced differently by men and women. Both the subjective and the objective strain and burden appear to be greater in female carers of dementia sufferers, and factors that influence this include differences in role expectations and coping strategies. These findings have implications for the provision of services for dementia sufferers and their carers.

REMCARE: reminiscence groups for people with dementia and their family caregivers - effectiveness and cost-effectiveness pragmatic multicentre randomised trial.

OBJECTIVES: The aim of the REMiniscence groups for people with dementia and their family CAREgivers (REMCARE) study was to assess the effectiveness and cost-effectiveness of joint reminiscence groups for people with dementia and their family caregivers as compared with usual care. DESIGN: A multicentre, pragmatic randomised controlled trial with two parallel arms - an intervention group and a usual-care control group - was carried out. A restricted dynamic method of randomisation was used with an overall allocation ratio of 1 : 1, restricted to ensure intervention groups of a viable size. Assessments, blind to treatment allocation, were carried out at baseline, 3 months and 10 months (primary end point). SETTING: Most participants were recruited through NHS Memory Clinics and Community Mental Health Teams for older people. Assessments were usually carried out in the person's home, and treatment groups were held in a variety of community settings. PARTICIPANTS: A total of 488 individuals (mean age 77.5 years) with mild to moderate dementia (meeting Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition criteria), who were initially living in the community, and who had a relative or other caregiver maintaining regular contact, who could act as an informant and was willing and able to participate in the intervention, were recruited to the study. Most carers were spouses (71%). A total of 350 dyads completed the study. INTERVENTIONS: The intervention consisted of joint reminiscence groups held weekly for 12 consecutive weeks, followed by monthly maintenance sessions for a further 7 months. The sessions followed a treatment manual, and were led by two trained facilitators in each centre, supported by a number of volunteers. Up to 12 dyads were invited to attend each group. MAIN OUTCOME MEASURES: The primary outcome measures were self-reported quality of life for the person with dementia and psychological distress for the carer [General Health Questionnaire-28 item version (GHQ-28)]. Secondary outcome measures included autobiographical memory and activities of daily living for the person with dementia, carer stress for the carer and mood, relationship quality and service use and costs for both parties. RESULTS: The intention-to-treat analysis identified no differences in outcome between the intervention and control conditions on primary or secondary outcomes [self-reported quality of life in Alzheimer's disease: mean difference 0.07, standard error (SE) 0.65; F = 0.48; p = 0.53]. Carers of people with dementia allocated to the reminiscence intervention reported a significant increase in anxiety on a subscale of the GHQ-28 at the 10-month end point (mean difference 1.25, SE 0.5; F = 8.28; p = 0.04). Compliance analyses suggested some benefits for people with dementia who attended more reminiscence sessions; however, carers attending more groups showed increased caregiving stress. Use of health- and social-care services was modest, with no significant difference in service use between conditions. Owing to negligible difference in quality-adjusted life-year gains (derived from European Quality of Life-5 Dimensions) between the conditions the planned full economic analysis was curtailed. CONCLUSIONS: This trial does not provide support for the effectiveness or cost-effectiveness of joint reminiscence groups for people with dementia and their carers. Although there may be some beneficial effects for people with dementia who attend sessions as planned, this must be viewed in the context of raised anxiety and stress in their carers. The reasons for these discrepant outcomes need to be explored further, and may necessitate reappraisal of the movement towards joint interventions.
