Abstract: BACKGROUND: Caregiving for people with dementia has consistently been linked with psychological problems, usually in terms of caregiver burden, general psychological distress and depressive symptomatology, while morbidity due to anxiety has been relatively neglected in this group. METHODS: We conducted a systematic review of the literature, searching electronic databases, reference lists, relevant systematic reviews and contacting experts in the field. We used Centre for Evidence Based Medicine (CEBM) criteria for inclusion and rating the validity of all studies that reported (1) the prevalence, predictors and covariates of anxiety disorders or anxiety caseness, and (2) covariates and predictors of the level of anxiety symptoms. RESULTS: Thirty-three studies met our inclusion criteria. Clinically, significant anxiety affects about a quarter of caregivers for people with dementia and was more common than in matched controls. Such caregivers have higher anxiety levels than controls, and that confrontative and escape avoidance coping, caregiver burden and poorer caregiver physical health are factors associated with higher anxiety levels from cross-sectional studies. CONCLUSIONS: Coping style may be more associated with anxiety than depression while other covariates (burden and poor physical health) are similar to those for caregiver depression. We found no conclusive evidence about factors associated with anxiety disorders or predicting anxiety from longitudinal studies. Neither care recipient cognition nor ADL impairment; nor caregiver age nor duration of caring are associated with caregiver anxiety levels. Good quality cohort studies are needed to determine whether these factors also predict anxiety disorders.

Abstract: BACKGROUND: Depression and phobic anxiety disorders are the most common psychiatric disorders in people aged 65 and over. SSRI antidepressants are effective in treating both conditions in younger people, and in treating depression in hospital samples of older subjects. No studies have investigated the efficacy of SSRIs in older people with these conditions living in the community. OBJECTIVES: To evaluate the efficacy and feasibility of treating older people suffering from depression and/or phobic anxiety in the community with fluoxetine alone. DESIGN: Subjects identified as depressed and/or anxious at screening were offered open-label fluoxetine and were reassessed for affective illness at 3 and 6 months. MEASURES: Outcome was assessed using the depression subscale of the Short Comprehensive Assessment and Referral Evaluation (Short-CARE) Scale and the Anxiety Disorder Scale. RESULTS: Of 67 subjects with depression and/or phobic anxiety, 55 (81%) were eligible to take fluoxetine. Fifty-four (98%) of these agreed to follow-up but only six (11%) agreed to take medication. No subject was still taking medication by the end of the study. Among those subjects on whom follow-up data were available, 70% of subjects depressed at screening and 97% of those with phobic anxiety retained their diagnoses at 3 months; at 6 months, the figures were 65% and 92% respectively. CONCLUSIONS: Drug treatment alone is not acceptable to older patients in the community with depression and phobic anxiety disorders. Discussion of symptoms with an appropriate professional is insufficient therapy on its own. Further work is needed to evaluate the effectiveness of a key worker such as a mental health nurse in coordinating treatment of patients with these disorders.

Abstract: OBJECTIVES: There have been few longitudinal studies investigating the impact of coping on psychological morbidity in caregivers of people with dementia. Findings have been inconsistent and little attention has been paid to anxiety in caregivers. We explored the hypothesis that the relationship between caregiver burden and anxiety and depression is mediated by coping style. METHODS: As part of the LASER-AD study, 93 (73.8%) people with Alzheimer's disease and their family caregivers recruited at baseline were re-interviewed 1 year later. Sampling aimed to ensure that the participants were representative of people living in the UK with Alzheimer's disease in terms of dementia severity, gender and care setting. We used the Hospital Anxiety and Depression Scale, the Zarit Burden scale and the Brief COPE to measure coping strategies. RESULTS: Using fewer emotion-focused strategies and more problem-focused strategies (but not dysfunctional strategies) mediated the relationship between caregiver burden and anxiety a year later, after controlling for potential confounders, in a well-fitting structural equation model (chi(2)=0.93, df=3, p=0.82; NFI=1.0, RFI=0.97, IFI=1.0, TLI=1.1, RMSEA=0.0). Using fewer emotion focused strategies also predicted higher psychological morbidity in general. The hypothesised relationship was not proved for depression. CONCLUSIONS: Using emotion-focussed coping strategies in response to caregiver burden seemed to protect caregivers from developing higher anxiety levels a year later; however using problem-focussed strategies did not. Our results suggest that a psychological intervention package to emphasise emotion-focused coping may be a rational approach to reduce anxiety in dementia caregivers. Studies are needed to test such interventions.

Abstract: BACKGROUND: Preliminary evidence indicates that the quality of the carer-care recipient relationship predicts those carers most at risk from anxiety. Attachment style is related to higher carer burden, psychological morbidity and increased care recipient institutionalization. We tested, for the first time, the hypothesis that carer burden and the coping strategies used mediate a relationship between attachment style and anxiety. METHODS: We interviewed 83 people with Alzheimer's disease and their family carers, originally recruited for a larger community study. Carers filled in a validated measure about their attachment style, the Hospital Anxiety and Depression Scale, the COPE to measure coping strategies, and the Zarit-Burden interview. RESULTS: More avoidant attachment (beta = 0.28) and less secure attachment (beta = -0.32) predicted anxiety. After adding coping strategies to the equation, the relationship with avoidant attachment (beta = 0.15) was no longer significant, and that with less secure attachment was reduced (beta = -0.23). A well-fitting structural equation model supported our finding that dysfunctional coping mediated the relationship between attachment style and anxiety. CONCLUSION: Carers who were less secure or more avoidantly attached reported higher anxiety. Interventions that aim to modify coping strategies have shown promise in reducing carer anxiety. Our finding that coping strategies also appear partially to explain the excess of anxiety among less securely attached carers suggests they are likely to benefit from such interventions.

Abstract: BACKGROUND: Many people with dementia live in residential homes, but little is known about their quality of life. AIMS: To compare the views of residents with dementia with the views of staff as to their quality of life, and to look at factors associated with these ratings. METHOD: The Quality of Life in Alzheimer's Disease (QoL-AD) scale was used to rate residents' and staff's perceptions of the quality of life of 238 residents of 24 residential homes in the UK. RESULTS: There were 119 QoL-AD scales completed by both residents and staff. For the residents, high QoL-AD scores strongly correlated with lower scores for depression (rho = -0.53, P < 0.0001) and anxiety (rho = -0.50, P < 0.001). In contrast, better quality of life as rated by staff correlated most strongly with increased dependency (rho = -0.53, P < 0.001) and behaviour problems (rho = -0.40, P < 0.001). CONCLUSIONS: The QoL-AD could be used as an effective measure of the quality of life of people with dementia in residential homes. Whereas mood was the main predictor of residents'own assessment of their quality of life, staff ratings were strongly linked with dependency. Staff should be aware that mood rather than level of dependency has a greater impact on residents' quality of life.

Abstract: BACKGROUND: Caregivers of people with dementia (CGPD) frequently have anxiety symptoms but little is known about the relationship of anxiety with coping strategies. METHOD: 126 people with Alzheimer's disease (AD) and their family caregivers living in the community were recruited from local psychiatric services, the voluntary sector and care homes. Sampling was designed to ensure that the sample was epidemiologically representative in terms of dementia severity, gender and care setting. We used the anxiety subscale of the Hospital Anxiety and Depression Scale (HADS) to measure anxiety and the Brief COPE to measure coping strategies. RESULTS: Use of dysfunctional coping strategies (Wald = 7.3, p = 0.007) and HADS depression caseness (Wald = 14.0, p < 0.001) were the only factors that predicted HADS anxiety caseness on logistic regression. LIMITATIONS: Anxious caregivers may be more likely to report their coping strategies negatively; these results do not clarify direction of causality. CONCLUSIONS: Dysfunctional coping strategies and depression appear to be the most important factors predicting caregiver anxiety. Addressing coping strategies may be a helpful intervention for managing caregiver anxiety.

Abstract: OBJECTIVES: Neuropsychiatric symptoms (NPS) are common in Alzheimer disease (AD). It is important in terms of management to know their natural history and their effects on service use. The authors aimed to determine the persistence and change in severity of NPS over 6 months in participants with AD, and the relationship to initial severity, drug management, use of services, and cost of care. METHODS: NPS scores and data on cognition, psychotropic medication, service use, and costs of care were collected on 224 participants at baseline and on 198 at 6-month follow-up. RESULTS: Of 224 patients, 210 (93.8%) had NPS at baseline; 168 (75.0%) had at least one clinically significant symptom, 118 (80.4%) of whom had persistent significant symptoms at 6-month follow-up. There was no significant change in mean NPS score for any symptom over 6 months, but many individuals became better or worse; 61.2% of those with at least one significant baseline symptom in any domain improved. Those with persistent symptoms had more severe baseline symptoms. Deterioration in NPS was predicted by deterioration in MMSE. Those with at least one clinically significant symptom had higher care costs than those without. CONCLUSIONS: NPS were highly persistent overall, but many individuals became better or worse. Persistence was predicted by having more severe symptoms at baseline. Clinically significant levels of NPS were associated with greater costs of care. The relatively few associations found between specific psychiatric treatments and changes in NPS reflect both undertreatment and the complexity of symptoms.

Abstract: OBJECTIVE: There are high rates of stress, distress, and psychological illness in family caregivers of people with dementia. Female caregivers and those caring for people with neuropsychiatric symptoms are particularly at risk. The authors report on the prevalence of anxiety and depression in a sample of family caregivers of people with Alzheimer disease (AD) and compare the characteristics of those who did or did not have those conditions. METHODS: A group of 153 people with AD and their caregivers were interviewed as part of a larger study of AD. RESULTS: In all, 23.5% of caregivers scored at or above caseness level for anxiety, and 10.5%, at levels for depression. Care-recipient (CR) activities of daily living (ADL) impairment, being a caregiver living with the CR, being a female caregiver, reporting a poorer quality of relationship with the CR, and caregivers reporting their health as being poor all predicted anxiety disorder. CR irritability, caregivers reporting poor health, and a poorer quality of relationship with the CR predicted depression. CONCLUSIONS: Clinicians should be aware of the high rates of anxiety as well as depressive symptoms in family caregivers of people with AD, especially in female caregivers. CRs and Caregivers' impaired physical health put them at risk for psychological morbidity and should be treated energetically. A poor-quality relationship between the caregiver and the CR predicts both caregiver depression and anxiety. Caregivers living with the CR are much more likely to be anxious than depressed.
