Effect of the Meeting Centres Support Program on informal carers of people with dementia: results from a multi-centre study.

Because of the complex nature of the problems that carers of persons with dementia encounter, several comprehensive support programs for carers were developed in the past decade. One such program is the Meeting Centres Support Program (MCSP) that integrates different types of support for persons with dementia and their carers, which have proved to be effective in practice and/or research. Within the framework of a study into the national implementation of the MCSP, it was investigated whether the positive effects found in carers that participated in the first Amsterdam Meeting Centres, were also achieved in other regions of The Netherlands. A pre-test-post-test control group design with matched groups was applied. In total, 94 carers in the MCSP in eight meeting centres and 34 carers of dementia patients who frequented regular psychogeriatric day care (PDC) in three nursing homes were included in the study. During the study period 23 carers of the MCSP group and 21 carers of the PDC group dropped out. At baseline and after seven months indicators of burden (psychological and psychosomatic symptoms, feelings of burden and time between start of support and institutionalization of the persons with dementia) were measured, as well as potential determinants of burden (sense of competence, coping strategies, experienced support, loneliness and the emotional impact of behaviour problems). Though on a group level no effect was found, either in psychological and psychosomatic symptoms or in the determinants of burden, a subgroup of carers who felt lonely (n=22) at baseline benefited significantly more from the MCSP than from PDC in terms of psychological and psychosomatic symptoms. A majority of MCSP carers (82.1%) experienced less burden and more professional support. After seven months significantly fewer persons with dementia in the MCSP (4%) were institutionalized as compared to the patients in PDC (29%). Patients in the MCSP participated for a longer period of time before institutionalization. Although the effect on sense of competence of carers that was found in the Amsterdam study was not found in this multi-centre study, the effect on burden and delayed institutionalization of the person with dementia were confirmed. The integrated MCSP also proved more effective than PDC in decreasing psychological and psychosomatic symptoms in lonely carers. Further dissemination of the MCSP is therefore recommended.

[Late-onset schizophrenia: is it a dementia nonpraecox? Review article with advice on differential diagnosis].

BACKGROUND: For many years now researchers have been discussing whether late-onset schizophrenia (LOS) is in fact a separate subgroup of schizophrenia. They also want to find out whether LOS has a neurodegenerative aetiology and is a progressive illness. AIM: To obtain insight into the clinical aspects, aetiological factors and the course of late-onset schizophrenia. In addition, advice is given about better ways of diagnosing LOS in clinical practice and about differentiating LOS from dementia. METHOD: The literature was searched via Medline and the Cochrane Library on the basis of the key words '(very) late-onset schizophrenia' and 'paraphrenia' combined with 'course', 'outcome', 'cognition', 'decline', 'white matter hyperintensities', 'MRI', and 'neuropsychological', 'postmortem' and cerebrospinal fluid'. The period studied was from 1960 to November 2004. RESULTS: Clinical parameters andfunctional and structural brain research point to differences from and similarities to the early form of schizophrenia (EOS). In cases of 'very-late-onset schizophrenia-like psychosis' (VLOS) the clinical differences vis-à-vis EOS are even more marked. It is not known to what extent neurodegenerative factors play a role. There is no clear consensus about the course of (V)LOS either. CONCLUSION: In view of the aetiologial and physiopathological factors it is still not clear whether (V)LOS can be differentiated from EOS on a neurobiological basis. There is insufficient proof about the extent to which (V)LOS is a dementia nonpraecox with neurodegenerative aetiology. To achieve clear differentiation between the various forms of dementia it is essential that the clinical diagnosis of LOS is supported as strongly as possible and is evaluated continually.

[The development of psychotic symptoms in later life: late-onset schizophrenia or frontotemporal dementia? A case study].

The diagnosis of psychotic disorders that develop later in life is complicated, as can be seen from the case of a 65-year-old woman. Initially she was admitted to hospital for psychotic depression, but after some time doubts arose regarding the diagnosis. The most striking symptoms were bizarre delusions with acoustic, haptic and gustatory hallucinations. In addition, she showed behavioral and personality changes. It is difficult to establish whether a patient has late-onset schizophrenia or frontotemporal dementia. The similarities and differences between the symptoms of these two disorders are discussed and advice is given to assist with clinicians with diagnosis in the future.

Depression and generalized anxiety disorder: co-occurrence and longitudinal patterns in elderly patients.

OBJECTIVE: The authors sought to establish the natural course and risk-profile of depression, generalized anxiety disorder (GAD), and depression with co-existing GAD in later life. METHODS: A total of 2,173 community-living elderly persons were interviewed at baseline, and at a 3-year follow-up. The course of "pure" depression, "pure" GAD, and depression with coexisting GAD was studied in 258 subjects with baseline psychopathology. Authors assessed bivariate and multivariate relationships between risk factors and course types. The risk-profile for onset of pure depression, pure GAD, and the mixed condition at follow-up was studied in 1,915 subjects without baseline psychopathology. RESULTS: Remission rate at follow-up was 41% for subjects with depression-only, 48% for pure GAD, and significantly lower (27%) for depression with coexisting GAD. A pattern of temporal sequencing was established, with anxiety often progressing to depression or depression with GAD. Onset of pure depression and depression with co-existing GAD was predicted by loss events, ill health, and functional disability. Onset of pure GAD, and, more strongly, that of depression with coexisting GAD, was associated with longstanding, possibly genetic vulnerability. CONCLUSIONS: In comparison with either depression-only or anxiety-only, the co-occurrence of these represents more severe and more chronic psychopathology, associated with longstanding vulnerability. In elderly persons, GAD often progresses to depression or to the mixed condition. These findings mostly favor a dimensional, rather than a categorical, classification of anxiety and depression.

[Explanations for the relation between depression and increased mortality].

Depression is a highly prevalent disorder at all levels of health-care delivery. Depression has an unfavourable effect on the prognosis of somatic illnesses, and is associated with excess mortality. Several mechanisms may contribute to these relationships. First of all, depression affects behaviour. Depressed patients show more unhealthy living habits, less compliance with medical treatment, and a higher number of accidents and suicides. Secondly, biological aspects of depression are important. Dysregulation of the neuro-immune system, hyperactivity of the hypothalamic pituitary adrenal axis, and autonomic dysregulation may all have a negative effect on both the prognosis of somatic illnesses and the lifespan. Although studies have suggested beneficial effects of the treatment of depression in (somatic) patients, it remains unclear whether treatment may also affect survival. Further research is needed to investigate the occurrence of and to unravel the mutual influences of depression and somatic illnesses, to search for possible pathogenetic mechanisms that may underlie both depression and medical disorders, and to assess the effects of depression treatment on biological parameters and survival.

Prevalence, correlates and recognition of depression in the oldest old: the Leiden 85-plus study.

BACKGROUND: Various studies support the notion that the clinical picture of depression in the oldest old differs from that in younger elderly. Moreover, withstanding the serious negative effects of depression on well being and functioning, the detection rate of depression in several medical settings is low. METHODS: Prevalence of depression, correlates and the rate of recognition by general practitioners were assessed in an 85-year-old community-based population. The GDS-S was applied in 500 participants with a MMSE >18, from a representative sample of 599 community based 85-year-old subjects. Demographic data, daily functioning, health correlates, use of medication and recognition of depression were recorded in home visits and from the general practitioner and pharmacists registers. RESULTS: The prevalence of depression, as measured with a GDS-S score of 5 points or more, was 15.4%, which is comparable to previous studies. No demographic factors were correlated with depression. Perceived health, loneliness, impaired mobility, cognitive decline and functional disability were major correlates of depression. From the participants who were seen by their general practitioner, 25% were recognised as depressed. Antidepressive pharmacotherapy was almost nonexistent. LIMITATIONS: Formal diagnosis of depression was not available. The data were collected cross-sectionally. CONCLUSIONS: Depression is highly prevalent in the oldest old and strongly associated with functional disability and cognitive impairment. It is important to enhance recognition of depression in community based oldest old as a first step to possible interventions.

Dysthymia in later life: a study in the community.

BACKGROUND: Dysthymia (DD) may be thought of as depression associated with personality disorder, a phase in the pleomorphic natural history of unipolar depression or a result of exposure to chronic physical illness. Prevalence, clinical features, risk factors and prognosis may change with AGE. METHOD: Large (n=3056) representative sample of elderly (55-85) in the Netherlands. Two-stage screen procedure to identify elderly with DD. The Center for Epidemiologic Studies Depression scale (CES-D) was used as a screen and the Diagnostic Interview Schedule (DIS) to diagnose DD. Data on 277 depressed elderly were available to assess the 6-year prognosis of DD. RESULTS: The prevalence of DD (4.61%) was higher in women and declined with age. The symptom profiles of DD and MDD were very similar. Those with DD were very likely to have had MDD earlier in life (44% in pure DD and 80% in those with double depression). The average age at onset (31 years) was earlier than in MDD (53 years). Environmental and personal vulnerability dominated the risk-factors. The prognosis was unfavourable in most cases. LIMITATIONS: Considerable attrition and retrospective data on age at onset and previous histories of depression. CONCLUSION: Although the prevalence declines with age, DD remains common in later life. Many cases arise later than is often thought and clinical features intertwine with those of MDD in the course of life. Given the unfavourable prognosis, provision of effective treatment is warranted.

Comorbidity and risk-patterns of depression, generalised anxiety disorder and mixed anxiety-depression in later life: results from the AMSTEL study.

BACKGROUND: Depression and generalised anxiety disorder frequently overlap. The question remains unresolved whether these are specific disorders, or that they represent different dimensions of a single disorder. Although both are highly prevalent disorders in this age group, studies on this issue in the elderly are scarce. Research is needed that investigates patterns of comorbidity and possibly different risk profiles for pure depression, pure generalised anxiety and mixed anxiety-depression in older people. METHODS: GMS-AGECAT diagnoses were obtained from 4051 community living older persons. Comorbidity was studied along a severity gradient for men and women separately. Multivariate analysis of risk factors included demographic variables, environmental vulnerability, longstanding vulnerability, physical/functional stresses and gender. RESULTS: The prevalence of pure depression was 12.2%, pure generalised anxiety 2.9%, mixed anxiety-depression 1.8%. Comorbidity increased with higher severity levels of both depression and generalised anxiety. Comorbidity was twice as likely in women than in men. Different risk profiles for diagnostic categories were not demonstrated for concurrent risk factors. Longstanding vulnerability was associated significantly stronger with mixed anxiety-depression than with pure anxiety and pure depression. Mixed anxiety-depression was overrepresented in women. CONCLUSIONS: Both lines of investigation suggest that, in the elderly, a dimensional classification is more appropriate than a categorical classification of depression and generalised anxiety. Mixed anxiety-depression is a more severe form of psychopathology that is almost specific to women in this age group.

The natural history of late-life depression: results from the Amsterdam Study of the Elderly (AMSTEL).

BACKGROUND: This study examines whether risk factors related to incidence of depression are also related to prognosis, and whether a vulnerability-stress model can be established for prognosis. METHODS: A prospective model for prognosis of depression (chronic or remitted course) in later life was studied in 236 depressed community-living elderly. Subjects were interviewed at baseline, and at follow-up 3 years later. Bivariate and multivariate relationships between risk factors and chronic depression (GMS-AGECAT) were assessed. Effect modification was studied between stressors and two types of vulnerability: vulnerability through a personal history of depression, and gender. RESULTS: A personal history of depression, baseline functional limitations and incident anxiety syndrome predicted chronic depression, whereas life-events occurring between assessments, and changes in physical, functional or cognitive status did not. In subjects without a previous history, functional disabilities, male gender and receiving instrumental support correlated with a poor prognosis. The prognosis for subjects with a personal history of depression was not affected by other factors. In women, the development of chronicity was more strongly associated with a personal history than in men, whereas in men recent psychosocial and health-related characteristics were more important than in women. LIMITATIONS: Because the study consisted of two measurements with a 3-year interval, depressive episodes with a short duration may be under-represented. CONCLUSIONS: In the elderly, the impact of risk factors on the course of depression is modified by longstanding vulnerability characteristics, such as a personal history of depression and gender. More recent life stresses are related to prognosis in subjects without a personal history, and in men.

[Depression among older nursing home patients. A review].

Depression is a common disorder in later life. The prevalence of depression in aged nursing home patients in 36 studies in various countries was reviewed. Results show prevalence rates ranging from 2% to 61%. Average prevalences were calculated for depressive symptoms, minor depression and major depression each. The averages thus found are 43.9% for depressive symptoms, 25.7% for minor depression and 15.5% for major depression. In order to find an explanation for the variation in occurrence of depression in nursing homes, factors that may have influenced the results are described. Both the definition of depression and the kind of instrument used in measuring depression appear to be highly responsible for the variations found.

Depression and cardiac mortality: results from a community-based longitudinal study.

BACKGROUND: Depression may be a potential risk factor for subsequent cardiac death. The impact of depression on cardiac mortality has been suggested to depend on cardiac disease status, and to be stronger among cardiac patients. This study examined and compared the effect of depression on cardiac mortality in community-dwelling persons with and without cardiac disease. METHODS: A cohort of 2847 men and women aged 55 to 85 years was evaluated for 4 years. Major depression was defined according to psychiatric DSM-III criteria. Minor depression was defined by Center for Epidemiologic Studies-Depression Scale scores of 16 or higher. Effects of minor and major depression on cardiac mortality were examined separately in 450 subjects with a diagnosis of cardiac disease and in 2397 subjects without cardiac disease after adjusting for demographics, smoking, alcohol use, blood pressure, body mass index, and comorbidity. RESULTS: Compared with nondepressed cardiac patients, the relative risk of subsequent cardiac mortality was 1.6 (95% confidence interval [CI], 1.0-2.7) for cardiac patients with minor depression and 3.0 (95% CI, 1.1-7.8) for cardiac patients with major depression, after adjustment for confounding variables. Among subjects without cardiac disease at baseline, similar increased cardiac mortality risks were found for minor depression (1.5 [95% CI, 0.9-2.6]) and major depression (3.9 [95% CI, 1.4-10.9]). CONCLUSION: Depression increases the risk for cardiac mortality in subjects with and without cardiac disease at baseline. The excess cardiac mortality risk was more than twice as high for major depression as for minor depression.

Emergence and persistence of late life depression: a 3-year follow-up of the Longitudinal Aging Study Amsterdam.

BACKGROUND: The present study was designed to assess onset and persistence of late-life depression, systematically comparing the factors associated with prevalence, onset and prognosis. METHODS: The data were derived from a large (n=2200), random, age and sex stratified sample of the elderly (55-85 years) in The Netherlands. Using a 3-year, prospective longitudinal design, both the onset and the persistence of depression were assessed. Depression was measured using the Center for Epidemiologic Studies Depression Scale. Risk factors associated with prevalence, onset and persistence were compared using both bivariate and multivariate analyses. RESULTS: In those not depressed at index assessment, the onset of depression was 9.7%. Among those depressed at baseline, persistence occurred in 50.4%. Risk factors predicting onset were almost identical to those associated with prevalence. Persistence was predicted by very few factors (external locus of control and chronic physical illness). CONCLUSIONS: The data suggest that cross-sectional studies are biased due to their overrepresenting chronic depressive episodes. However, the risk factors derived from cross-sectional studies do seem to adequately reflect factors associated with onset. The prognosis is not adequately predicted by variables usually included in epidemiological studies of late life depression. It is speculated that including more biological correlates of depression and data concerning positive life-changes may improve our understanding of the prognosis of late life depression.

The quality of nursing home care: do the opinions of family members change after implementation of emotion-oriented care?

OBJECTIVE: The present study focuses on opinions on the quality of nursing home care of family members of nursing home residents with dementia. Furthermore, we examined whether family members' appreciation of the care increased as a result of the implementation of emotion-oriented care. DESIGN: Randomized clinical trial. INSTRUMENT: An 18-item questionnaire was developed. The following subjects were addressed: communication activities between staff and family members; satisfaction regarding contacts with staff; the extent to which family members can participate in care; the contact that family members experience with the person with dementia, and opinions about the way in which nursing staff treat residents. RESULTS: Most family members already had a positive opinion on the nursing home care prior to the implementation of emotion-oriented care. The most positive assessment concerned the way in which nursing staff treated residents. The lowest scores concerned communication activities between ward staff and family members. Comparison of the first and end measurements showed that in general opinions on the quality of care did not change. STUDY LIMITATIONS: A large number of incomplete questionnaires made it impossible to conduct factor analysis on the classification of the questions in various sections and therefore allowed us only to make statements at the item level. CONCLUSIONS: For the most part family members had a positive opinion on the nursing home care. In general, implementation of emotion-oriented care did not lead to a more positive assessment. Despite the generally accepted notion that involving family members in care is important, family members were regularly treated as outsiders. This demonstrates that there is room for improvement in the communication by nursing home staff with family members (e.g. more frequent contacts and information about the illness).

Predictors of change in anxiety symptoms of older persons: results from the Longitudinal Aging Study Amsterdam.

BACKGROUND: Data on the course of anxiety in late life are scarce. The present study sets out to investigate the course of anxiety, as measured by the HADS-A (Zigmond & Snaith, 1983) in community dwelling older persons, and to evaluate predictive factors for change over 3 years in anxiety symptoms following the vulnerability/stress model. METHOD: Based on the first anxiety assessment, two cohorts were formed: subjects with and subjects without anxiety symptoms. In the non-anxious cohort (N = 1602) we studied risk factors for the development of anxiety symptoms; in the anxious cohort (N = 563) the same factors were evaluated on their predictive value for restitution of symptoms. Risk factors included vulnerability factors (demographics, health status, personality characteristics and social resources) and stressors (life events occurring in between both anxiety assessments). Logistic regression models estimated the effects of vulnerability factors, stress and their interaction on the likelihood of becoming anxious and chronicity of anxiety symptoms. RESULTS: It was indicated that the best predictors for becoming anxious were being female, high neuroticism, hearing/eyesight problems and life-events. Female sex and neuroticism also increased the likelihood of chronicity of anxiety symptoms in older adults, but life events were not related to chronicity. The main stressful event in late life associated with anxiety was death of one's partner. Vulnerability factors and stress added on to each other rather than their interaction being associated with development or chronicity of anxiety. CONCLUSION: The vulnerability/stress model offers a useful framework for organizing risk factors for development and chronicity of anxiety symptoms in older persons, but no support was attained for the hypothesis that vulnerability and stress amplify each others effects. Finally, the results indicate to whom preventive efforts should be directed: persons high in neuroticism, women, and those who experience distressing life events.

Effect of integrated family support versus day care only on behavior and mood of patients with dementia.

OBJECTIVE: This study tests the hypothesis that integrated family support, in which patients and caregivers are both supported by one professional staff, is more effective in influencing behavior problems and mood of the dementia patient than nonintegrated support, such as psychogeriatric day care only. DESIGN: A quasi-experimental pretest-posttest control group design with matched groups was applied. SETTING: Psychogeriatric day-care centers of four community centers and three nursing homes. PARTICIPANTS: Fifty-six dementia patients living at home and their caregivers. INTERVENTION: The patients in the experimental group (n = 33) participated together with their caregivers in an integrated family support program, whereas the patients in the control group (n = 23) received psychogeriatric day care only. MEASUREMENTS: Behavior problems and mood were observed using standardized behavior observation scales. RESULTS: After 7 months the experimental support program, compared to the regular psychogeriatric day care, showed a large positive effect on the total number of behavior problems (effect size .75), and also specifically on the degree of inactivity (effect size .66) and nonsocial behavior (effect size .61). No effect on mood was found. CONCLUSIONS: In influencing the total amount of behavior problems, as well as the degree of inactivity and nonsocial behavior, the integrated family support program proved to be more effective than psychogeriatric day care. Because behavior problems are an important determinant for admission of persons with dementia into a nursing home, integrated family support may contribute to the delay of institutionalization.

Comorbidity of the anxiety disorders in a community-based older population in The Netherlands.

OBJECTIVE: The aim of the study was to investigate patterns of comorbidity among the anxiety disorders in a community-based older population, and the relationship of these disorders with major depression, use of alcohol and benzodiazepines, cognitive impairment and chronic somatic illnesses. METHOD: The data were derived from the Longitudinal Aging Study Amsterdam (LASA) study. A two-stage screening design was adopted to identify respondents with anxiety disorders. RESULTS: In total, 10% of the elderly with an anxiety diagnosis suffered from two or more anxiety disorders. Major depression (13% vs. 3%), benzodiazepine use (24% vs. 11%) and chronic somatic diseases (12% vs. 7%) were significantly more prevalent in respondents with an anxiety disorder than in respondents without anxiety disorders. Heavy or excessive alcohol intake (5% vs. 4%) and cognitive impairment (11% vs. 13%) were not significantly associated with any anxiety disorder. CONCLUSION: When anxiety disorders are diagnosed, in older people there is a relatively high probability of comorbid conditions being present.

Depressive symptoms and risk of Alzheimer's disease in more highly educated older people.

BACKGROUND AND OBJECTIVE: In an earlier study we observed that a depressive syndrome was highly predictive of developing Alzheimer's disease (AD) in older persons with normal baseline cognition and higher levels of education. We interpreted these findings as the depression being an early noncognitive manifestation of AD in persons with more cognitive reserve. The present study examines whether specific symptoms of depression can be identified that predict AD among older subjects with higher levels of education. DESIGN AND PARTICIPANTS: In the community-based Amsterdam Study of the Elderly (AMSTEL), a sample of 3,147 nondemented persons with normal cognition, 65 to 84 years old, was selected and divided into subjects with >8 years and < or =8 years of education. At baseline, the presence or absence of 12 specific symptoms of depression was assessed. At follow-up, patients with incident AD were diagnosed according to DSM-IV criteria in a two-step diagnostic procedure. RESULTS: After an average follow-up of 3.2 years, 1,911 persons were reevaluated, of whom 22 with > 8 years and 31 with < or =8 years of education had developed AD. Multivariate logistic regression analyses showed that among persons with >8 years of education depressed mood and subjective bradyphrenia were strongly associated with incident AD. No association between depressive symptoms and AD was observed among subjects with < or =8 years of education. CONCLUSIONS: Both depressed mood and subjective bradyphrenia seem to indicate subclinical AD in older people with higher levels of education. Clinicians should be alert that in these persons, AD may become apparent within a relatively short period of time.
