The use of legal guardians and financial powers of attorney among home-dwellers with Alzheimer's disease living with their spousal caregivers.

We conducted a cross-sectional survey of a random sample of 1943 spouses of home-dwellers with Alzheimer's disease (AD) to examine the prevalence of court-appointed guardians or financial powers of attorney for persons with AD, related factors and the need for information about these issues among caregiving families. The questionnaire consisted questions on variables of demographic characteristics, disability, symptoms and care needs of the person with dementia, the strain of caregiving, the use of court-appointed legal guardians or powers of attorney, as well as discussions about these issues -- and the need for them -- with a doctor. The response rate was 77% and the mean ages of those with AD and caregivers were 80.2 and 78.2 years, respectively. The use of legal guardians was rare (4.3%), while the use of financial powers of attorney was more common (37.8%). Only 9.9% of the couples had discussed these issues with their doctor, whereas 47.9% expressed a need for it. The factors associated with the use of these legal arrangements were related to the severity of dementia, including experiencing dementia symptoms for more than 3 years, poor functioning, incontinence and behavioural symptoms. There is a clear need for information on medico-legal issues related to dementia among caregivers of AD patients. If held soon after the diagnosis, such discussions could support the autonomy of these persons in spite of AD and enable them to plan for the future as they wish.

How do elderly spouse care givers of people with Alzheimer disease experience the disclosure of dementia diagnosis and subsequent care?

OBJECTIVES: To examine the experiences of spousal care givers of Alzheimer patients to disclosure of dementia diagnosis and subsequent care. METHODS: A random sample of 1943 spousal care givers of people receiving medication for Alzheimer disease (AD) was sent a cross-sectional postal survey about their opinions on the disclosure of dementia and follow-up care. A smaller qualitative study (n = 63) included open-ended questions concerning their experiences of the same topics. RESULTS: The response rate for the survey was 77%. Of the respondents, 1214 of 1434 acknowledged themselves as their spouse's care giver. The mean age of the care givers was 78.2 years, and that of demented spouses, 80.5 years. Of the care givers, 63% were women. The couples had long-lasting marriages (mean 52 years). Of the care givers, 93% reported that dementia had been disclosed openly to their spouse; 97% also preferred that physicians openly inform the patients of the dementia diagnosis, although 55% of their spouses with AD had developed depressive symptoms after the disclosure. Of the care givers, 71% felt they had received sufficient information about dementia. However, only 50% estimated that their spouses' follow-up care had been well organised. The responses in the qualitative study indicated that many care givers felt grief and anxiety. They also expressed feelings of loneliness and uncertainty about how to deal with follow-up care for dementia. CONCLUSIONS: Elderly spousal care givers were quite satisfied with the information given them about dementia. However, the support with regard to the follow-up care of care-giving families failed to meet their needs adequately.

Positive life orientation as a predictor of 10-year outcome in an aged population.

OBJECTIVE: It is well known that depression predicts mortality in old age. However, little is known about the impact of positive emotions. We investigated the impact of positive life orientation on mortality and permanent institutional care in aged birth cohorts. STUDY DESIGN AND SETTING: Participants (born 1904, 1909, and 1914) underwent detailed assessments with follow-up at 5 and at 10 years. Positive life orientation was determined as answering "yes" to all the following items: being satisfied with life, having zest for life, having plans for the future, feeling needed, seldom feeling lonely or depressed. RESULTS: Of participants, 102 (20.8%) had a positive life orientation. After 10 years, 54.5% of them were alive, whereas in the rest of the sample 39.5% survived (P=.004). After controlling for age, gender, and health measures, the impact of positive life orientation was still significant (HR=0.89, 95% CI 0.83-0.93). At 5 years, only 2.9% of those having a positive life orientation but 17.5% of the rest of the sample were in permanent institutional care (P=0.003), with a positive life orientation remaining a significant protector against institutional care (OR 0.58, 95% CI 0.36-0.93). CONCLUSION: Positive attitudes have a long-standing impact on prognosis in old age.

Precipitating factors of delirium: stress response to multiple triggers among patients with and without dementia.

BACKGROUND AND AIM: Delirium is common and serious acute syndrome among older people precipitated by multiple external factors such as acute illnesses, trauma, surgery, and drugs. The aim of this study was to find possible stressors and causative triggers for acute delirium and compare patients with or without dementia in this respect. METHODS: 193 delirious patients from two separate delirium studies including settings of nursing homes and geriatric wards were thoroughly assessed for precipitating factors of delirium. Patients with and without dementia were compared for their clinical status, symptoms and signs, prognosis, and the profile of precipitating factors of delirium. RESULTS: The patients with dementia (n=98) and without dementia (n=95) did not differ in their demographic factors, mean number of drugs, or their psychiatric symptoms. The patients with dementia had higher number of comorbidities, poorer cognition, and they were more often restrained than those without dementia. The mean number of precipitators for delirium was 2.6 among those without dementia and 2.0 among those with dementia (p=0.0019). Infections, metabolic conditions, trauma, and surgery were more common precipitating factors for delirium in those without than those with dementia. There was no difference in mortality between the groups. CONCLUSION: Most patients had multiple precipitating factors for delirium irrespective of prior dementia. Those with dementia and decreased cognitive reserves needed lower number of etiologies to develop delirium. The profile of causative agents differed among patients with and without dementia.
