Complaints of informal caregivers providing home care for dementia patients: the Pixel study

Information needs and information seeking behaviour of people with dementia and their non-professional caregivers: a scoping review

Background

People with dementia often require full-time caregivers especially in the later stages of their condition. People with dementia and caregivers’ access to reliable information on dementia is essential as it may have an important impact on patient care and quality of life. This study aims to provide an overview of the information needs and information seeking behaviour of people with dementia and their non-professional caregivers.

Methods

We conducted a scoping review of the literature and searched four electronic databases for eligible studies published up to August 2018. Two reviewers independently screened studies and extracted data. Information needs were classified according to emerging themes in the literature, and information seeking behaviour was categorized using Wilson’s model of information behaviour.

Results

Twenty studies with a total of 4140 participants, were included in this review. Reported information needs focused on: (i) disease; (ii) patient care provision; (iii) healthcare services; and (iv) caregiver self-care. The most commonly reported information need was on healthcare service-related information. Characteristics found to influence information needs were the severity of dementia as well as patient and caregiver status. People with dementia and non-professional caregivers mainly displayed active searching, information seeking behaviour and preferred using electronic sources to obtain health information.

Conclusion

Current dementia information sources available in English are extensive in the information they offer, but more emphasis needs to be placed on healthcare service-related information. All studies originated from high income countries and focused on information needs of non-professional caregivers only. The only variables found to be associated to information needs were severity of dementia condition as well as patient/caregiver status. The information needs identified in this review can be used to inform development and design of future dementia resources for people with dementia and their non-professional caregivers.

Neurocognitive disorders: what are the prioritized caregiver needs? A consensus obtained by the Delphi method

Background

The symptoms related to neurocognitive disorders (NCD) may lead to caregiver burden increase. Involving caregivers in research may be an effective way of improving the practicalities and relevance of interventions. The aim of this study was to gather opinion and gain consensus on the caregivers ‘priorities, using a Delphi method and including aspects of needs in pharmaceutical dimension.

Methods

Observational study using a modified Delphi method. This study was conducted in the Clinical and Research Memory Center of the University Hospital of Lyon (France), between September 2015 and January 2016. The expert panel was composed of 68 informal caregivers of people with subjective cognitive decline or NCD living at home.

Results

Caregivers assigned a very high importance to the dimension “information needs about their relative’s disease”, i.e. information on the disease, the treatment and the research; and to “coping skills”, i.e. skills related to emotional support, communication, relationship evolution with the relative and skills to cope with behavioural crisis, behavioural and cognitive disorders. The aspect “coping with behavioural disorders” received a high selection rate (83%).

Conclusions

The main needs selected can be used to design relevant interventions and give guidance to policy to support caregivers. To meet caregiver’s needs, interventions should focus on information about disease and treatment and psychoeducational interventions.

The male familial caregiver experience of caring for persons with Alzheimer's disease from low socio-economic status: A South African perspective

The aim of this study was to explore the experiences of male familial caregivers of persons with Alzheimer’s disease from low socio-economic status using the ecological systems theory perspective. The data were obtained from 11 semi-structured interviews that were conducted with the familial caregivers of persons with Alzheimer’s disease. Data were analyzed using thematic analysis, where four main themes emerged, namely, relationship difficulties, understanding Alzheimer’s disease, support networks, and finding meaning and satisfaction in the caregiving role. Behavioral problems, erosion of the relationship with the significant other, familial conflict, experience of diagnosis, lack of information, lack of free time, and financial concerns were identified challenges facing caregivers. Provision of information, support groups, social support, community-based support, and finding meaning and satisfaction in the caregiving role were reported as resources that assist in caregiver coping. Men seem to be capable of providing effective care and are able to successfully manage in their caregiving role. Culture seems to play a significant role in help-seeking behavior and the approach to caregiving. The findings provide the basis for the specific needs of male caregivers that should be focused on in order to provide culturally appropriate services to enhance caregiver coping amongst male caregivers in similar settings.

[Biopsychosocial approach to caregiving burden: Why should we care about caregivers' health?]

There are 11 million family caregivers in France and some estimates indicate that there will be 17 million in 2020. Caregiving is a source of chronic stress that requires adaptation and coping strategies. Caregiving may benefit the health of a caregiver with a positive coping style and altruistic goals. However, the caregiver's burden is frequently associated with negative effects in terms of biopsychosocial imbalance and medical conditions, with frequent anxiety and depression. The management of the caregiving burden starts with the recognition of health professionals - caregivers may benefit from consultation-liaison psychiatry and multidisciplinary medico-social strategies, in addition to constant support from their GPs.

Effectiveness of Cognitive Behavioral Therapy for Caregivers of People with Dementia: A Systematic Review and Meta-Analysis

BACKGROUND AND PURPOSE

Caregivers endure tremendous physical, emotional, and financial burdens while caring for people with dementia. The current study aimed to estimate the effectiveness of cognitive behavioral therapy (CBT) for caregivers of people with dementia (CGPWD).

METHODS

Studies in the MEDLINE, EMBASE, Cochrane Library, Web of Science, and SCOPUS databases were screened. Studies with a randomized controlled design and which produced CBT outcomes for CGPWD were included in this study, and we investigated these outcomes.

RESULTS

The screening of abstracts of 263 studies resulted in 12 randomized controlled trials being included in this study. The mean age of the CGPWD ranged from 51.5 to 66.2 years. The caregiver role was most frequently adopted by a female spouse or daughter. CBT for the CGPWD resulted in positive effects on various conditions, including depression, anxiety, stress, and dysfunctional thoughts. Depression was the most commonly evaluated condition, and the Center for Epidemiologic Studies Depression Scale (CES-D) was most frequently used as an inventory for depressive symptoms. The mean differences between the baseline and postintervention CES-D scores were compared between the CBT-intervention and control groups. The CES-D score decreased significantly more in the CBT-intervention group than in the control group. The difference in pooled mean differences between the two groups was -4.98.

CONCLUSIONS

CBT is an efficient intervention tool for reducing the various emotional burdens experienced by CGPWD. This meta-analysis found that CBT significantly improved the depressive symptoms of CGPWD.

Factors Affecting Burden of South Koreans Providing Care to Disabled Older Family Members

This study examined the determinants of caregiving burden among South Koreans who care for their disabled older family members. A sample of 1,000 primary caregivers taken from the Comprehensive Study for Elderly Welfare Policy in Seoul, South Korea was analyzed. Independent variables included the demographic characteristics of caregivers and care recipients, the severity of cognitive impairment among care recipients, care recipients' functional abilities, financial adequacy and caregivers' degree of social support. Hierarchical regression was used to predict the levels of caregivers' burden. Similar to western care providers, South Korean caregivers who were in poor health and who had little informal social support, inadequate financial resources and more weekly caregiving hours were more likely to experience intense caregiving burden. Burden was also positively related to the functional and cognitive disabilities of care recipients. The results of this study indicate that certain aspects of caregiving are unique to South Koreans. Daughters-in-law were the most common caregiver within the sample which indicates that South Korean eldercare is non-consanguineous. Identifying predictors of South Korean caregivers' burden promotes a more comprehensive understanding of cultural experiences in caring for older adults.

Ageing and trajectories of depressive symptoms in community-dwelling men and women

OBJECTIVE

The aim of this study was to investigate age-related patterns of depressive symptoms in older men and women and to identify their determinants.

METHODS

The Center for Epidemiological Studies Depression Scale was used to prospectively assess depressive symptoms in 1059 men and 1531 women, enrolled in a French representative population-based cohort (PAQUID study) and followed over a period of 20 years. Using a group-based trajectory method with an accelerated longitudinal design, we modelled the course of depressive symptoms between 65 and 104 years of age and examined associations between trajectory patterns and baseline socio-demographic and health variables.

RESULTS

In men, we identified three rising trajectories: 'never depressed' including 65% of the sample, 'emerging depression' (28%) and 'increasing depression' (7%). Compared with the membership of the never-depressed trajectory, that of the two higher trajectories was significantly associated with a history of depression and dyspnoea. In women, we identified two slightly rising trajectories (never depressed, 56%, and 'rising subclinical', 33%) and one stable high trajectory ('persistent depression', 11%). Membership of the two higher trajectories was significantly associated with the use of benzodiazepine, polymedication and dyspnoea. A history of nondepressive psychiatric disorder was a risk factor for membership of the persistent-depression group, whereas being widowed seemed to be a protective factor for membership of this group.

CONCLUSION

High-risk groups for later-life depression should be targeted differently in older men and women in order to implement appropriate interventions to prevent chronicity and disability.

Psychosocial correlates of nutritional status of family caregivers of persons with dementia

BACKGROUND

This exploratory study investigated the associations of individual characteristics of both persons with dementia and family caregivers with the nutritional status of caregivers.

METHODS

This cross-sectional study was conducted at home by psychogerontologist within the frame of a community gerontological center in rural areas of south west France. The study participants comprised 56 community-dwelling persons with dementia (mean 80.7 years, SD 6.5) and 56 family caregivers (mean 70.9 years, SD 11.0). Persons with dementia were assessed with Mini-Mental State Examination (MMSE), Basic Activities Of Daily Living (ADL), Instrumental ADL (IADL), and NeuroPsychiatric Inventory (NPI), and family caregivers with the Burden Interview (Zarit scale), the State-Trait Anxiety Inventory (STAI Y-B), the Center for Epidemiologic Studies Depression Scale (CES-D), the emotional impact measure of NPI and the Autonomy, Gerontology and Group Resources scale (AGGIR scale). For both, nutritional status was evaluated using the Mini Nutritional Assessment (MNA®).

RESULTS

Among family caregivers, 32.1% were at risk of malnutrition and 5.4% were malnourished, and among people with dementia, 58.9% and 23.2%, respectively. NPI severity score of apathy of persons with dementia (Beta = -0.342, p = 0.001), dependency on AGGIR scale (Beta = -0.336, p = 0.002), and CES-D score of caregivers (Beta = -0.365, p = 0.001) were associated with caregivers' MNA score (Adjusted R 2 = 0.480, p < 0.001).

CONCLUSION

These preliminary findings emphasize the need for routine assessment of depressive symptoms, functional and nutritional status in dementia family caregivers, and confirm the value of investigating caregivers' nutritional risk through an integrative view including psychosocial approach.

Sleep disturbance in mental health problems and neurodegenerative disease

Sleep has been described as being of the brain, by the brain, and for the brain. This fundamental neurobiological behavior is controlled by homeostatic and circadian (24-hour) processes and is vital for normal brain function. This review will outline the normal sleep-wake cycle, the changes that occur during aging, and the specific patterns of sleep disturbance that occur in association with both mental health disorders and neurodegenerative disorders. The role of primary sleep disorders such as insomnia, obstructive sleep apnea, and REM sleep behavior disorder as potential causes or risk factors for particular mental health or neurodegenerative problems will also be discussed.

Lived experiences of Iranian family member caregivers of persons with Alzheimer's disease: caring as 'captured in the whirlpool of time'

AIMS AND OBJECTIVES

This study aimed to understand the experiences of Iranian family caregivers of persons with Alzheimer's disease.

BACKGROUND

Increasing rate of Alzheimer's disease along with the ageing population has made this disease an urgent public health challenge worldwide. As non-professional caregivers, family members play a significant role in delivering care to elders, most of whom have one or more chronic diseases. Family-based caregiving has expanded with the encouragement of non-institutionalisation but at the same time creates challenges for caregivers.

DESIGN

A qualitative study was conducted using Heideggerian hermeneutic phenomenology.

METHODS

Eight Iranian family caregivers of persons with Alzheimer's disease were interviewed. Interviews were audio-taped and transcribed; data were analysed by Van Manen's methodology.

RESULTS

One of the most important themes that emerged was 'captured in the whirlpool of time', which also contained the subthemes of 'reminiscence of past' and 'being afraid of the future'. Family caregivers frequently remembered their common past experiences when interacting with their loved ones with Alzheimer's disease, as though travelling with him/her to the past. Furthermore, caregivers continually compared the past abilities of their relative with their present condition, which resulted in feelings of loss and regret. Further, the unpredictable nature of Alzheimer's disease created fear about the future deterioration of the condition and caregivers' future suffering.

CONCLUSIONS

The findings demonstrated the necessity of providing continuous education and support for family caregivers of persons with Alzheimer's disease.

RELEVANCE TO CLINICAL PRACTICE

Nurses are among front-line professionals who are in a position to support and provide information for family caregivers of persons with Alzheimer's disease.

Mechanisms of action of a psychological intervention for dementia caregivers: effects of behavioral activation and modification of dysfunctional thoughts

OBJECTIVE

Different studies show the negative effects on caregivers' health of maladaptive thoughts and the positive effects of engaging in pleasurable activities on distress. The aim of this study is to (a) test the efficacy of a cognitive-behavioral intervention aimed at training caregivers to flexibilize maladaptive thoughts regarding caregiving and increasing their leisure activities and to (b) analyse the mediator role in the effects of the intervention of caregivers' change in dysfunctional thoughts and behavioral activation.

METHODS

A total of 170 caregivers were contacted and randomly distributed to the intervention condition or to the control group. Depression, behavioral activation, and dysfunctional thoughts were assessed at baseline and post-intervention by 'blinded' interviewers. The intervention consisted in twelve group based sessions in which in addition to cognitive-behavioral techniques, caregivers' were trained in basic principles for caring for a relative with dementia.

RESULTS

Significant intervention by time effects were found for depression, dysfunctional thoughts and frequency of leisure activities. Only significant positive effects were found for the intervention group. The regression analysis for testing mediational effects of dysfunctional thoughts and leisure activities on the relationship between participating on the intervention and changes in depressive symptomatology show that mediation is established in both cases.

CONCLUSIONS

The results of our study contribute to the literature on interventions for dementia caregivers highlighting the positive mediator effect that modifying caregivers' dysfunctional thoughts and increasing their behavioral activation has on caregivers' depressive symptomatology.

The organisation of dementia care by families in Malta: The experiences of family caregivers

This paper discusses the experiences of dementia family caregivers in Malta. The study design was essentially exploratory as this is the first funded social research on dementia in the island of Malta. In-depth semi-structured interviews were conducted in October 2008 with 17 caregivers. Identification of caregivers was through their relatives’ attendance at a hospital based outpatient memory clinic. Interviews were recorded, transcribed and when required, phrases were translated from Maltese to English. A thematic analysis was guided by the questions; What are the experiences of family caregiving in Malta? And what impact does caregiving have for individual/family life? Three key findings are discussed, namely: the organization of family care in Malta; the use of formal services; and the dislocation of dementia caregiving experiences from wider community life. This paper raises questions about support mechanisms currently available in Malta while presenting cross-national learning opportunities to apply established knowledge to the Maltese context.

Growing and gaining through caring for a loved one with dementia

Aim: To investigate the gains experienced by family caregivers of persons with dementia.

Methods: Twelve respondents were recruited using purposive sampling from three institutions around Singapore. A qualitative design, guided by the grounded theory approach, was adopted and involved semi-structured, in-depth, face-to-face interviews. The interviews were recorded, transcribed and analyzed using open, axial and selective coding.

Results: All caregivers interviewed reported having gained from caregiving. The most common gain was that of `personal growth' which comprised being more patient/understanding, becoming stronger/more resilient, having increased self-awareness and being more knowledgeable. Another theme that emerged was `gains in relationships' whereby caregivers experienced an improvement in their relationship with the care recipient, with others in the family or in their ability to interact with other older persons. The third gain experienced was that of `higher-level gains' which encompassed gains in spirituality, deepened relations with God, and a more enlightened perspective in life.

Discussion: This research supports a shift from the conventional focus on burdens to a more holistic approach that considers how caregivers can grow and emerge stronger from the caregiving experience. This has implications in the design and delivery of services as utilizing these gains as a coping resource may enable better support for caregivers. It is pertinent that professionals supporting caregivers internalize the perspective of gains so that it becomes a natural way of seeing their clients and in the process help caregivers find meaning and enrichment in their caregiving journey.

Sense of coherence amongst male caregivers in dementia

The aim of this study was to explore the experiences of men caring for spouses suffering from dementia from a salutogenic perspective. The study focused on the experiences of ten men caring for a spouse with dementia. Primarily qualitative analysing methods were utilized. Data were obtained from semi-structured interviews conducted with male spouses of patients with dementia. An orientational analysis approach was followed and the data was analysed in terms of Antonovsky's sense of coherence construct. Qualitative findings were compared to participant responses to quantitative measures. Stressors most often reported were cognitive impairment, behaviour problems, a lack of free-time, erosion of the relationship, family conflict and financial concerns. Factors facilitating caregiver coping included support from their daughters, their ability to find meaning and satisfaction within the context of the care-giving task, and the successful utilization of active, problem-focused coping strategies. Men generally appear to be effective and capable caregivers. However, their approach to care giving differs from that of their female peers. Task-oriented problem-solving, effective use of the available support resources and the ability to find both meaning and satisfaction in their caring appear characteristic of effective male caregivers of demented spouses.

Service use in family caregivers of persons with dementia in Belgium: psychological and social factors

This study aims to investigate whether selected social and psychological characteristics of family caregivers of persons with dementia are related to community-based service use in Belgium. Two aspects were distinguished in service utilisation: volume (number of contacts) and diversity (number of services). Within a selected region, dementia caregivers were traced via the detection of persons with dementia known to community health or social services. A probability diagnosis was made with the Geriatric Mental State and the computer algorithm AGECAT. Family caregivers of persons with dementia (N = 168) were interviewed at home by means of a structured questionnaire. Data were analysed with multiple regression analysis. Co-residence, a positive attitude towards home service use, and increased problem-solving coping were found to be direct predictors of increased diversity of services used, whereas a lower burden of behaviour problems, living apart, and increased avoidance coping were found to be direct predictors of increased volume of service use. Care recipients' behaviour problems and functional status were not found to be related to service use. The results suggest that social and psychological factors have a larger impact on service use in family caregivers of persons with dementia, compared to objective or subjective burden. Interventions to increase awareness of relevant services, to improve attitudes towards their use and support problem-solving coping in family caregivers may be considered to increase the use of appropriate services.

An evaluation of a specialist multiagency home support service for older people with dementia using qualitative methods

BACKGROUND

Standard home care support for people with dementia has been criticised in statutory inspection reports, and may lead to unnecessary crises, hospital or care home admissions.

OBJECTIVE

To establish whether a specialist multiagency home care service for older people with dementia delivered better quality care than standard services, and how any improvements were achieved.

DESIGN

Qualitative study, using semi-structured interviews, focus groups and small group interviews.

SETTING

Two demographically similar areas in Nottingham, one served by a specialist home care team, the other by standard services.

PARTICIPANTS

Twenty-seven service users, 18 family carers, 17 home care workers, 20 health/social care professionals, across both services.

RESULTS

The specialist service demonstrated greater flexibility and responsiveness to the particular needs and circumstances of service users and family carers, who were encouraged to participate in routine decision-making and activities. By sharing responsibilities, the specialist service helped reduce carer stress and prevent crises. These outcomes depended on the configuration of the service, including multidisciplinary health and social services input, careworker autonomy and independence, continuous reassessment of clients' circumstances and preferences and the capacity to develop long-term relationships, through careworker continuity. The standard service, which used a task-orientated approach, lacked these characteristics.

CONCLUSIONS

This study provides evidence of the benefits of a specialist multiagency home support service over standard home care, in the opinion of service users, carers and careworkers, and defines the operational model that achieves this. Findings confirm best practice recommendations, based on models of dementia care which emphasise respect for 'personhood'.

Does day care also provide care for the caregiver?

People caring for relatives with dementia may need respite to be able to cope and maintain some quality of life. With the aim to investigate whether day care is an effective form of respite for caregivers of dementia sufferers, 115 new day care clients were invited and 90 caregivers agreed to participate. Of these, 51 fulfilled the inclusion criteria and were asked to assess feelings of worry, depression, overload and role captivity before using day care and again 4 months later. The study group comprised both co-residing (CR) and non-co-residing (NCR) caregivers and care recipients. Those NCR caregivers whose elderly relative dropped out of day care had significantly higher values for worry, overload and role captivity, and a higher level of depression than the caregivers in the NCR group whose care recipient continued day care. Although this study is of an explorative character, some conclusions may be drawn from it. Dementia sufferers seem to need an informal caregiver to help them when they are not at day care. Day care is probably a form of support most suitable for caregivers, who are looking after relatives in the early stages of the illness and are not yet too exhausted.

Environnement contenant chez la personne âgée démente – Étude Pixel

Caregivers of demented outpatients can suffer from poor health, are often anguished and unable to cope with the cared patient, and this burden can generate frailty.

OBJECTIVES

This survey attempted to determine the psychological parameters and effective capability influence of the caregiver's Quality of Life (QoL) and vulnerability, and measured the consequences of their alteration.

METHODS

4 categories of situations were studied, according to the angst and coping capability of caregivers. Caregiver's QoL and vulnerability were assessed in these situations. Data were related to the socio-demographic data of both patients and their principal caregivers, and to the patients' medical and therapeutic data.

RESULTS

1,410 and 10 patients diagnosed with dementia who lived at home with their principal caregivers were recruited for this survey. Angst and inability to cope with patients alter caregivers' QoL and was correlated to their vulnerability. Female caregivers were often in these situations, had a poorer QoL and were more vulnerable than men. Caregivers anguished and/or nab to cope with the cared patient were less satisfied with their own care and did not enjoy their relationships with their patients. Caregivers with psychological difficulties and failure to cope had to deal with nutritional difficulties with the demented patient.

DISCUSSION

Caregivers' QoL and vulnerability, are related to angst and inability to cope with patients. We could imagine that both patients and caregivers would benefit by taking care of carers.

Relation entre événements de vie, traumatismes et démence; étude ouverte portant sur 565 patients déments

SUMMARY

Ageing is due to a progressive loss of the person's adaptation capability, whereas during this period environmental aggression increases. In the elderly, life events re-present a psychological traumatism that overwhelms the old person and related family, disrupting and fragilising homeostatic balance. A number of authors have suggested a possible link between life traumatisms and the dementia processes. The aim of this study is to reveal the presence of life traumatisms preceding the apparition of the dementia syndrome.

METHOD

This is a retrospective and comparative work based on the PIXEL study on complaints and demands from the principle informal caregivers of Alzheimer patients. It includes 565 patients presenting the criterion of dementia as defined by the DSM IV, and questionnaires filled out by the principle caregivers. One item of the questionnaire referred to life events which could have played a part in the development of the disorder. In a second stage, the reported events were classified into 4 distinct categories: loss, repeated or prolonged stress, psychotraumatism and depression-inducing events. The statistics were produced using SAS and Stat 10 software. Student's test, ANOVA and chi2-test were used.

RESULTS

372 caregivers answered the first item (65%); 76 of them believed there was no event while 296 related the disorder to one or several life events (79% of responders, 52% of the sample). These results confirm Persson and Clement's study which evidenced a higher frequency of stressing life events for subjects afflicted with dementia as compared with older people without any psychic disorder. Reported events and their respective frequency: spouse death (15.39%), parents' death (15%), familial difficulty (10.08%), anaesthesia (8.49%), child's death (4.42%), somatic disturbance (4%), depression (3.89%), retirement (3.89%), financial problems (2.65%), loneliness (2.65%), removal (1.76%), fall (1%), alcohol (0.8%), traumatism (0.53%), spouse care (0.35%), leaving for home care, storm and caregiver change in life (0.17%). Regrouping the data: 82.71% of the answers can be connected to prolonged stress, 62.85% to real or symbolic loss, 39% to a psychotraumatic event and finally, most of these events can potentially induce depression.

DISCUSSION

Some of the events refer to difficulties concerning people close to the subject (death of a close relation, hospitalisation of husband or wife) in a period when the loss of autonomy or handicap means greater dependence on surrounding people. General anaesthesia is mentioned by 48 caregivers. In fact, this usually implies surgery, the presence of organic pathology or the need for hospitalisation, which we know has a destabilizing effect in the elderly. It is therefore not surprising that 23 answers mentioned somatic disorders (4% of the sample). According to Leger, it's mostly a loss type event which is implied in the elderly. Such losses would induce a weakening of cognitive stimulation which could decompensate an infraclinical dementia or accelerate an emerging dementia process. Antecedents of depressive illness are considered as an element of risk for the development of Alzheimer's disease. Depression is spontaneously mentioned by 22 caregivers. We must add the many reported life events which are well known to induce depression in older people. Most of the events considered in this study are liable to provoke manic mood swings. Depression resulting from life events can be considered either as an affection occurring along with dementia or as the aggravating factor of an infraclinical process or, finally, as an additional factor of vulnerability. With older people, many events may constitute a trauma because of the proximity of death and because of their sudden onset (fall, hospitalisation, somatic illness). Several studies have pointed out that a particularly traumatic event could enhance the risk of dementia. Life events associated with chronic or repeated stress are characterized by their permanence or their repetition. According to a general psychosomatic biological pattern, psychic distress will engender a series of degradations or an acute or chronic response to an early trauma. According to this hypothesis, prolonged exposure to an excess of glucocorticosteroids at the time of a disadaptative stress would have deleterious effects on the hippocampus. Indeed, the hippocampus plays a part in a number of functions affected by dementia such as memory, learning process and emotional adjustment. This study takes into account stress factors ("stressors") but not factors influencing their impact on the subject such as an individual predisposition (genetic, psychopathologic, coping abilities) and social support. The force of the impact of these events on older people and what is really experienced by them remain unknown. This study strengthens a number of others evincing an unusual frequency of life events in dementia processes. According to an integrative pattern, repeated or prolonged stress could be a deciding factor in the degenerative process or a factor of decompensation with older people presenting a genetic, biological or psychological vulnerability to dementia. The impact of such life events would vary according to the subject's pre-morbid personality, coping abilities and the support he/she can rely on.

CONCLUSION

Some life events may be involved in the dementia process as shown by the results of this study, but this relationship does not imply direct causality. It's difficult to appreciate whether these results are not a consequence of the greater attention paid to the patient after the appearance of the first symptoms, leading to a closer observation. Stress could trigger the degenerative process. This argues for the necessity of an early diagnosis taking into account a traumatic event of life either precocious or late.

Gender differences in caregiver stressors, social resources, and health: an updated meta-analysis

This meta-analysis integrates results from 229 studies on gender differences in caregiver psychological and physical health, caregiving stressors, and social resources. Contrary to common perceptions, gender differences in caregiving variables were small to very small. Women had higher levels of burden and depression, and lower levels of subjective well-being and physical health. They reported that their care recipient had more behavioral problems; they provided more caregiving hours, helped with more caregiving tasks, and assisted with more personal care. Women and men did not differ in the use of informal and formal support. Statistically controlling for gender differences in stressors and resources reduced the size of gender differences in depression and physical health to levels that have been observed in noncaregiving samples. The results support stress-and-coping theories on gender differences in caregiving.

Dementia patients caregivers quality of life: the PIXEL study

BACKGROUND

Alzheimer's disease and related syndromes have heavy social and human consequences for the patient and his family. Beyond the neuropsychiatric effects of specific therapies for dementia, one of today's challenges is the quality of life for both patients and their informal caregivers.

OBJECTIVES

This survey tends to determine parameters influencing caregivers' quality of life, and its possible link with patients' quality of life.

METHODS

A scale measuring caregivers' quality of life, developed from data from previous PIXEL studies was used. It is a questionnaire composed of 20 items. The scale was related to the socio-demographic data of both patients and their main caregivers, to the ADRQL scale (Alzheimer Disease Related Quality Life) of Rabins for the QoL of dementia patients, to the patients medical and therapeutic data, specially a neuropsychological inventory: Folstein's cognition test, Cornell's depression scale, the fast battery of frontal assessment, Katz's dependence index, Cummings' neuropsychiatric inventory for behavioral and psychological symptoms of dementia and to a physician evaluation of caregiver's depression.

RESULTS

One hundred patients diagnosed with dementia who live at home with their principal caregivers were recruited for this survey. Patients were 80.2 +/- 6.8 years old and caregivers were 65.7 +/- 12.8 years old. The caregivers' quality of life was correlated to the quality of life of the patients they cared for, the importance of behavioral disorders, and the duration of dementia evolution. Women caregivers had a worse quality of life and were more depressive than men.

DISCUSSION

Caregivers' and patients' quality of life are related and both share a community of distress.

Genetic testing for colon cancer among African-Americans in North Carolina

OBJECTIVE

To describe attitudes and correlates of intention to take a genetic test for colon cancer in a population-based sample of African-Americans.

METHODS

African-Americans (n = 658), age 18-70, in North Carolina completed an 11-page questionnaire between June-October 2003 that assessed attitudes (familiarity, perceived benefits and risks, anxiety, and confidentiality) and intention to take a genetic test for colon cancer and various participant characteristics.

RESULTS

Respondents expressed favorable attitudes and high intention regarding genetic testing for colon cancer: 87% would definitely/probably take a genetic test, although only 42% had read/heard a lot or some about genetic testing. Most agreed that genetic test results should be available to healthcare providers (79%) but not to health insurers (62%) or employers (82%). About a third were concerned that genetic testing could lead to discrimination. Correlates of intention differed by sex. Perceived benefits were significantly positively associated with intention among all respondents. However, being married (OR = 2.1, 95% CI: 1.2, 3.7), doctor as the main source of health information (OR = 2.4, 95% CI: 1.4, 3.9), and colon cancer family history (OR = 4.3, 95% CI: 1.6, 11.6) were significant only for women; some college education (OR = 4.1, 95% CI: 1.7, 9.7), importance of sharing test results with relatives (OR = 5.5, 95% CI: 1.6, 18.7), and colon cancer screening history (OR = 3.4, 95% CI: 1.6, 7.5) were only significant for men.

CONCLUSIONS

Respondents expressed high interest in genetic testing for colon cancer risk, although confidentiality of test results is a concern. Guidelines and policies for genetic testing specific to African-Americans should be established and future research should examine the prevalence of genetic testing.

Les symptômes psychologiques et comportementaux de la démence : description et prise en charge

Behavioral and Psychological Symptoms in Dementia (BPSD) are, beside cognitive disorders, major features of Alzheimer's disease and related disorders. Diagnosis is important to enhance our knowledge of the pathophysiology of dementia and of their functional consequences for patients and caregivers. Pharmacological and non-pharmacological management of dementia depends to a large extent on the presence of BPSD. A committee of geriatricians, neurologists and psychiatrists specialized in dementia (THEMA 2) has promoted an epidemiological, diagnostic and therapeutic update in this field. This work was based on the BPSD Consensus Conference Report edited in 2000 by the International Psychogeriatric Association. This report was updated with the most recent literature reports, and was adapted to the French environment.

Knowing the diagnosis and counselling the relatives of a person with dementia: the perspective of home nurses and home care workers in Belgium

Home nurses and home care workers share the care for a person with dementia with family caregivers, and are confronted with their needs for medical and service-related information, for advice on how to cope with the behaviour changes, and for emotional support. The first objective of the present study was to describe some of the conditions for effective counselling, such as the perception that knowing the diagnosis has positive consequences for the formal caregivers. A second objective was to describe the formal caregivers' counselling practice, and ascertain its relationship with the psychological variables of attitudes, self-efficacy and subjective norm. A postal questionnaire was sent to 287 home nurses and 1259 home care workers in a defined region of Belgium; the questionnaire was returned by 169 home nurses (58.9% response) and 665 home care workers (52.8% response). The Theory of Planned Behaviour was the organising framework which underpinned the development of the instruments. Only the 168 home nurses and 601 home care workers reporting experience with caregiving to people with dementia were included in the analysis. Formal caregivers indicated that knowing the diagnosis was important, but it could facilitate or hinder caregiving. They were able to describe behavioural characteristics which are indicative of dementia, but only in a limited way, and their strategies to uncover the diagnosis were also limited. Formal caregivers reported that they supported family members emotionally, advised about communication with the person with dementia and informed family caregivers about services. However, providing family caregivers with information about dementia lagged behind these forms of support. In general, nurses scored higher than home care workers. Multiple linear regression analysis was used to investigate the relationships between self-reported practice and the concepts of the model. In both professions, attitudes and self-efficacy were found to be strong independent predictors, and the implications for practice are discussed.

Comparison of clinic-based home assessment to a home visit in demented elderly patients

Home visits assessing demented elderly patients yield important information but are perceived to be expensive. We investigated the utility of a home assessment during a clinic visit. A total of 200 demented subjects attending an outpatient geriatric assessment program were enrolled in a prospective, repeated-measures design study comparing the yield of a structured clinic-based home assessment with the yield of a home visit (the criterion standard). A total of 172 subjects completed the protocol. The average age was 76 +/- 7 years, 68% were female, 48% married, and the average Mini-Mental Status Examination score was 21 +/- 7 points. Only 3 subjects had complete agreement by site, 162 subjects had at least one problem identified only at the home visit, and 7 subjects had at least one problem identified only at the clinic. There were 376 problems identified at both sites, 422 identified only by the home visit, and 478 identified only in the clinic. Problems related to patient safety and caregiver issues were the two most common general categories. Eighty-four percent of the problems identified only at the home visit were potentially serious and 24% of problems identified at both sites were rated as more serious at the home visit. A clinic-based home assessment is not comparable to a home visit for assessing the home environment of demented elderly patients.
