Post-stroke dementia and depression: frontosubcortical dysfunction as missing link?

OBJECTIVE: Testing the hypothesis that depressive symptoms in dementia reflect dysfunction in fronto-subcortical pathways. BACKGROUND: Both depression and dementia can be the result of vascular damage of the brain. The nature of the depressive symptomatology seems to be related to concommittant cognitive disturbances in that subjects show more so-called motivational symptoms of depression. These symptoms can be the result of frontal-subcortical dysfunction. It could be very helpful for clinical practice if these subjects could be identified by simple diagnostic procedures. METHODS: Associations were computed between measures of depressive symptoms and a set of neuropsychological tests in a sample of 54 subjects with a post-stroke dementia. RESULTS: Although we used an extensive set of neuropsychological tests, most subjects were able to participate only in a small part of them, because of disease severity. Our hypothesis was supported by a negative correlation between scores on the verbal semantic fluency task and the total numbers of motivational depressive symptoms. None of the neuropsychological tests was significantly related to the number of mood symptoms neither did they correlate with the total number of depressive symptoms. CONCLUSION: This study gives further evidence for the assumption that motivational-based depressive symptoms partially originate from fronto-subcortical dysfunction.

The relationship between generalized anxiety disorder, depression and mortality in old age.

BACKGROUND: The association between depression and an increased risk of death in elderly persons has been established in both clinical and community studies. Co-occurrence of depression and generalized anxiety has been shown to represent more severe and more chronic psychopathology. However, little is known about the relation between generalized anxiety disorder, mixed anxiety-depression (generalized anxiety disorder and depression) and excess mortality in the elderly. OBJECTIVE: To investigate whether generalized anxiety and mixed anxiety-depression are associated with mortality. METHOD: Generalized anxiety disorder, mixed anxiety-depression and depression were assessed in 4051 older persons with a ten-year follow-up of community death registers. The mortality risk of generalized anxiety, depression and mixed anxiety-depression was calculated after adjustment for demographic variables, physical illness, functional disabilities and social vulnerability. RESULTS: In generalized anxiety disorder and mixed anxiety-depression no significant excess mortality was found. In depression a significant excess mortality was found in men [HR 1.44 (1.09-1.89)] but not in women [HR 1.04 (0.87-1.24)] after adjustment for the different variables. CONCLUSIONS: In elderly persons depression increases the risk of death in men. Neither generalized anxiety nor mixed anxiety-depression are associated with excess mortality. Generalized anxiety disorder may even predict less mortality in depressive elderly people. The relation between generalized anxiety disorder and its possibly protective effect on mortality has to be further explored.

Clinically defined vascular depression in the general population.

BACKGROUND: Vascular depression is regarded as a subtype of depression, especially in, but not entirely restricted to, the elderly, characterized by a specific clinical presentation and an association with (cerebro)vascular risk and disease. It could have major implications for treatment if subjects at risk for such a depression could be easily identified by their clinical presentation in general practice. METHOD: We studied the symptom profile of depression in subjects with and without vascular risk factors in two large Dutch community-based studies, the Rotterdam Study and the Amsterdam Study of the Elderly (AMSTEL). RESULTS: We could not confirm the specific symptom profile in depressed subjects with vascular risk factors in either of the two cohorts. Depressed subjects with vascular risk factors showed more loss of energy and more physical disability than those without vascular risk factors. However, presumed specific symptoms of vascular depression, namely psychomotor retardation and anhedonia, were not significantly associated with any of the vascular risk indicators. Loss of energy was significantly associated with myocardial infarction and peripheral arterial disease. CONCLUSIONS: In these two large community-based studies we identified some differences between vascular and non-vascular depressed subjects but found no evidence for a specific symptom profile of vascular depression as previously defined.

The contribution of working conditions and social support to the onset of depressive and anxiety disorders among male and female employees.

Poor working conditions may be an important source of stress and may therefore contribute to the development of depressive and anxiety disorders. Social support may act as a buffer and protect against the development of depression or anxiety in the face of poor working conditions. With longitudinal data from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), the effect of working conditions and social support on the incidence of depressive and anxiety disorders was examined among 2646 working men and women, aged 18 through 65 years. Three dimensions of self reported working conditions were assessed: psychological demands, decision latitude and job security. Social support was assessed through validated scales for daily emotional support. About 10.5% of working women and 4.6% among working men developed an incident depressive and/or anxiety disorder over 2 years. Psychological demands predicted the incidence of depressive and anxiety disorders in both men and women (RR per score increase=2.29, 95% CI: 1.44-3.63), whereas decision latitude and job security did not. Social support protected against the incidence of depressive and anxiety disorders. This effect was stronger for men compared to women. Social support did not buffer the unfavorable mental effect of working conditions. Women were more likely to report low levels of decision latitude, whereas men reported higher psychological demands. Working conditions did not explain sex differences in the incidence of depressive and anxiety disorders.

Cerebrovascular risk factors and subsequent depression in older general practice patients.

BACKGROUND: This general practice-based case-control study tested the association between cerebrovascular risk factors (CVRFs) and the development of later-life depression by focusing on the impact of exposure duration to CVRFs and the modifying influence of age at depression onset. METHODS: Cases were 286 patients aged > or = 50 years with a first diagnosis of depression at age > or = 50 years. Nondepressed controls (N=832) were individually matched for age, gender and practice. CVRF diagnoses (hypertension, diabetes mellitus, cardiovascular conditions) prior to depression were determined. Analyses controlled for education, somatic and nondepressive psychiatric disease. RESULTS: No CVRF variable examined was significantly associated with subsequent depression in the total sample. An unexpected impact of age at onset of depression was observed: the odds ratio associated with having any CVRF was smaller for patients with age at onset > or = 70 years than for patients with onset between ages 50-59 years (p=.002) and 60-69 years (p=.067). Subsequent analyses excluding patients with onset at age > or = 70 years revealed that CVRF variables, including long-term exposure to CVRFs, significantly increased the odds of subsequent depression with onset between ages 50 and 69 years. LIMITATIONS: Reliance on GPs' records of morbidity may have resulted in bias towards underestimation in patients with depression onset at age > or = 70 years. CONCLUSIONS: Our findings suggest that CVRFs play a relevant role in the development of depression with onset between ages 50 and 69 years, but no evidence was found that they contribute to the occurrence of depression with onset at age > or = 70 years. Replication is warranted to exclude the possibility of bias.

Personality and the onset of depression in late life.

BACKGROUND: This study addresses the question whether personality is a predictor for becoming depressed in late life. We expect that personality traits are significantly associated with the onset of depression, but that the effect of personality is overwhelmed by the effect of health related variables. The second research question concerns whether the strength of this association is affected by the influence of age or age-related deteriorations in the other prognostic factors. We hypothesize to find that a high neuroticism level or low levels of mastery, self-efficacy or self-esteem strengthen the impact of the health-related variables and social situational factors on the onset of depression in late life. METHODS: Out of a population-based baseline sample (Longitudinal Aging Study Amsterdam) of 1511 non-depressed elderly respondents (55-85 years at baseline), 255 (17%) developed a clinically relevant level of depressive symptoms during the 6-year follow-up period. Data on the effect of personality on onset were analysed using logistic regression analyses. RESULTS: Both at univariate and multivariate level, the personality traits studied predicted the onset of depression. The effect of neuroticism was more strongly related to onset than health-related and social factors. Results revealed no significant interaction effects between the personality characteristics and age or the other prognostic factors on the association with onset of depression. DISCUSSION: Personality, neuroticism in particular, was found to be a consistent and important predictor of the onset of depressive symptoms in late life, even more important than health-related and situational factors, and aging did not affect the strength of this association.

Late-life depression: the differences between early- and late-onset illness in a community-based sample.

BACKGROUND: Several studies have described etiological and clinical differences between elderly depressed patients with early onset of their illness compared to late onset. While most studies have been carried out in clinical samples it is unclear whether the findings can be generalized to the elderly population as a whole. The aim of this study was to compare early-onset (EOD) and late-onset (LOD) depressive illness in a community-based sample. METHODS: Large (n = 3107) representative sample of older persons (55-85 years) in the Netherlands. Two-stage screen procedure to identify elderly with MDD. The Center for Epidemiologic Studies Depression scale (CES-D) was used as a screen and the Diagnostic Interview Schedule (DIS) to diagnose MDD. Data on 90 older persons with early-onset depression and 39 with late-onset depression were available. RESULTS: Those with LOD were older, and more often widowed. Family psychiatric history, vascular pathology, and stressful early and late life events did not differ between groups. EOD subjects had more often double depression and more anxiety. CONCLUSIONS: In a community-based sample we did not detect clear differences in etiology and phenomenology between EOD and LOD. This discrepancy with reports from clinical samples could be due to selection bias in clinical studies. Consequently, all patients with late-life depression deserve a diagnostic work-up of both psychosocial and somatic risk factors and treatment interventions should be focused accordingly.

Differences in heart rate variability between depressed and non-depressed elderly.

OBJECTIVE: To determine whether older primary care patients with a Major Depressive Disorder (MDD) have lower heart rate variability (HRV) compared to non-depressed patients. HRV is a measure of cardiac autonomic functioning. METHOD: A cross-sectional comparison of 136 elderly persons with MDD and 136 non-depressed controls (matched for age and gender) recruited in family practices in the Netherlands. Depression was determined according to the DSM-IV criteria using the PRIME-MD. HRV was measured with an electrocardiogram (ECG) during a 5-minute supine rest. RESULTS: Multivariate analyses showed statistically significant decrease in HRV in MDD patients compared with controls. CONCLUSION: Older primary care patients with MDD have a reduced HRV. This may explain why depression is a risk factor for cardiovascular disease and mortality.

Well-being, physical functioning, and use of health services in the elderly with PTSD and subthreshold PTSD.

OBJECTIVE: To measure the impact of PTSD and subthreshold PTSD on daily life functioning, well-being and health care use in a community based-sample of the elderly population in the Netherlands. METHODS: Consequences of PTSD were investigated in an elderly community-based population (LASA study) by comparing three groups: subjects with PTSD, with subthreshold PTSD, and a reference group. Indicators of well-being (loneliness, self-perceived health and satisfaction with life), disability (days spent in bed and disability days) and use of health care (general practitioners, medical specialists, psychiatrists, mental health care, social workers and professional home care) were investigated. RESULTS: In comparison to the reference group, subjects with PTSD or subthreshold PTSD spent more days in bed due to illness and had more disability days, even when corrected for concurring other diseases or functional limitations. They were less satisfied with life in general, used health care for predominantly somatic care and evaluated the care they received to be inadequate. Psychotropic drugs, if prescribed, were predominantly benzodiazepines and seldom antidepressants. CONCLUSIONS: The findings strongly suggest that elderly with either PTSD or subthreshold PTSD suffer grave impairments in daily life, are less satisfied with life and do not receive optimum treatment. Especially elderly with PTSD frequently visit medical specialists but are rarely treated by psychiatrists or other mental health professionals, nor do they receive antidepressant treatment from their GP. Lack of adequate treatment may be the cause of dissatisfaction with the care they receive.

The impact of depression and anxiety on well being, disability and use of health care services in nursing home patients.

OBJECTIVE: To determine the impact of depression and anxiety on well being, disability and use of health care services among nursing patients. METHODS: The study-population consisted of 350 elderly nursing home patients from 14 nursing homes in the Netherlands. Well being, disability, use of health care services (i.e. assistance in ADL, paramedical care, number of medications) and depression and anxiety and other relevant characteristics (gender, age, education, marital status, urbanization, cognition, morbidity, social support) were measured cross-sectionally. Associations of well being, disability and use of health care services with independent baseline characteristics were assessed with bivariate and with multivariate analyses. RESULTS: Presence of depression and/or anxiety was associated with significantly less well being, but not with more disability. Presence of depression and/or anxiety was also significantly associated with four of the seven indicators of health care service use measured in this study: less assistance in ADL, more consultation of medical specialists, a higher mean number of medications and more use of antidepressants. CONCLUSION: Presence of depression and/or anxiety has a statistically and clinically significant negative impact on well being, but not on disability. Future studies should focus on interventions for improving the detection, diagnosis and treatment of depression and/or anxiety in the nursing home.

Socioeconomic differences in incident depression in older adults: the role of psychosocial factors, physical health status, and behavioral factors.

OBJECTIVE: The objective of this study was to examine the association between socioeconomic status (SES) and the onset of depression in older adults and to determine the relative contribution of psychosocial factors, physical health status, and behavioral factors in explaining this link. METHODS: Data were from 2593 men and women, aged 55-85 years, participating in the Longitudinal Aging Study Amsterdam. Two indicators of SES were used: education and income. The onset of depression was measured over 9 years of follow-up. RESULTS: Adjusted hazard ratios of incident depression were significantly higher in those with low education and low income. Psychosocial factors explained on average 16% of the SES differences in incident depression, physical health status on average 7%, and behavioral factors less than 5%. CONCLUSION: In older adults, low SES predicted the incidence of depression. Part of this association was explained by psychosocial factors and physical health status.

Nurses' recognition and registration of depression, anxiety and diabetes-specific emotional problems in outpatients with diabetes mellitus.

OBJECTIVE: The aim of this study was to investigate how often emotional problems were recognized and registered by diabetes nurses. METHODS: We studied medical charts and questionnaire data of 112 diabetes patients. The hospital anxiety, depression scale and the problem areas in diabetes survey were used to measure anxiety, depression and diabetes-specific emotional distress. RESULTS: In patients with moderate to severe levels of anxiety or depression, the presence of an emotional problem was recorded in the medical chart in 20-25% of the cases. The registration-rate of diabetes-specific emotional distress was also found to be low, ranging from 0% (treatment-related problems) to 29% (diabetes-related emotional problems). CONCLUSION: Registration-rates of emotional problems by diabetes nurses were found to be low, but quite similar to detection rates of physicians and nurses in studies with non-diabetic samples. PRACTICE IMPLICATIONS: These findings suggest that recognition-rates of emotional problems in diabetes patients need to be increased. Future studies should investigate whether recognition and subsequent treatment of emotional problems in diabetes patients can be facilitated by utilizing validated, standardized self-report questionnaires.

Depression in older age is a risk factor for first ischemic cardiac events.

OBJECTIVE: Depressive disorders have been shown to be associated with cardiac diseases and death, but the underlying disease mechanism is unclear. The authors hypothesized that the cardiac morbidity and mortality after depression in late life is mediated by subclinical atherosclerosis and is thus confined to ischemic heart diseases. METHOD: Using the population-based cohort of the Longitudinal Aging Study Amsterdam, 2,403 men and women aged 55 and over without cardiac disease were followed to assess the onset of cardiac disease or cardiac death. Ischemic heart diseases (angina pectoris, [non]fatal myocardial infarction) were distinguished from other cardiac diseases (congestive heart failure, arrhythmia). Major depressive disorder (MDD) was defined according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition (DSM-III) criteria. Subthreshold depression was defined as clinically relevant depressive symptoms not fulfilling DSM criteria. RESULTS: After a mean follow up of 7.2 years, 444 first cardiac events occurred, of which 252 were primary ischemic events and 192 other cardiac events. Cox regression analysis adjusted for physical health variables showed that, when compared with nondepressed respondents, those with MDD had a relative risk (RR) of 2.09 (95% confidence interval: 1.13-3.85) for any cardiac event. Considering only ischemic events, the RR conferred by MDD increased to 3.00 (1.51-5.93), whereas the RR declined to 0.96 (0.24-3.89) for all other cardiac events. Subthreshold depression did not increase the risk of future cardiac events. CONCLUSION: Major depression in older age predicts first cardiac events. The excess cardiac morbidity and cardiac mortality after major depression could entirely be attributed to ischemic heart diseases.

Incidence and outcome of depressive symptoms in nursing home patients in the Netherlands.

OBJECTIVES: To assess incidence and outcome of depressive symptoms among nursing home (NH) patients and to identify clinical characteristics predicting onset and persistence of depressive symptoms. METHODS: Depressive symptoms (GDS>10) and relevant correlates were assessed at baseline and at follow-up (6 months) in 350 NH-patients of 14 Dutch NH's with the Geriatric Depression Scale (GDS). Predictors of onset and persistence were studied using chi-square statistics and multiple logistic regression analyses. RESULTS: The prevalence of depressive symptoms decreased from 41.3% to 28.9% during six months follow-up. The onset of depressive symptoms in those without depressive symptoms at baseline was 4.7%, while the rate of persistence was 63.3%. Persistence of depressive symptoms was more frequent in patients with higher GDS-scores (18-30) at baseline. No baseline characteristics were associated with onset of depressive symptoms. Persistence of depressive symptoms was only associated with more years of education. CONCLUSIONS: Pre-admission factors and transition may largely be responsible for depressive symptoms among nursing home patients. The observed substantial decrease in prevalence of depressive symptoms over six months is largely due to remission of depressive symptoms present at baseline. Adaptation of nursing home patients to pre-admission factors, facilitated by the nursing home environment, may explain this observed decrease of depressive symptoms. Future studies should evaluate interventions targeted at patients with higher GDS-scores (18-30).

Prevention of late-life depression in primary care: do we know where to begin?

OBJECTIVE: This study attempted to compare two models for selective (people at elevated risk) and indicated (those with subsyndromal depressive symptoms) prevention and to determine the optimal strategy for prevention of late-life depression. METHOD: Onset was assessed at 3 years with the Geriatric Mental State AGECAT in a randomly selected cohort of 1,940 nondepressed and nondemented older people in Amsterdam. Risk factors that can easily be identified in primary care were used. RESULTS: The association of risk factors with depression incidence was expressed in absolute and relative risk estimates, number needed to treat, and population-attributable fractions. Prevention models were identified with classification and regression tree analyses. In the indicated prevention model, subsyndromal symptoms of depression were associated with a risk of almost 40% of developing depression and a number needed to treat of 5.8, accounting for 24.6% of new cases. Adding more risk factors raised the absolute risk to 49.3%, with a lower number needed to treat but also lower attributable fraction values. In the selective prevention model, spousal death showed the highest risk, becoming even higher if the subjects also had a chronic illness. Overall, the attributable fraction values in the indicated model were higher, identifying more people at risk. CONCLUSIONS: Consideration of the costs and benefits of both models in the context of the availability of evidence-based preventative interventions indicated that prevention aimed at elderly people with depressive symptoms is preferred. The focus on treatment should be readdressed; a new approach is needed, with a stronger emphasis on prevention.

Natural history of depression in the oldest old: population-based prospective study.

BACKGROUND: Despite its negative consequences, little is known about the natural history of depression in the oldest old. AIMS: To study the incidence, course and predictors of depression in the general population of the oldest old. METHOD: The Leiden 85-plus Study is a prospective population-based study of 500 people from their 85th to their 89th birthdays. Depressive symptoms were annually assessed with the 15-item Geriatric Depression Scale, using a cut-off of 4 points. RESULTS: During a mean follow-up of 3.9 years, the annual risk for the emergence of depression was 6.8%. Poor daily functioning and institutionalisation predicted depression. Among the 77 participants with depression at baseline (prevalence 15%) the annual remission rate was ony 14%. In more than half of the participants with a remission of depression, we observed a relapse of depression during follow-up. No predictors of remission could be identified. CONCLUSIONS: Among the oldest old, depression is frequent and highly persistent. More active case-finding and treatment would be potentially rewarding.

Comorbidity of depression and anxiety in nursing home patients.

OBJECTIVES: To assess the occurrence and risk indicators of depression, anxiety, and comorbid anxiety and depression among nursing home patients and to determine whether depression and anxiety are best described in a dimensional or in a categorical classification system. METHODS: DSM and subthreshold anxiety disorders, anxiety symptoms, major and minor depression and depressive symptoms were assessed in 333 nursing home patients of somatic wards of 14 nursing homes in the north west of the Netherlands with the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Geriatric Depression Scale (GDS). Comorbidity was studied along a severity gradient. Logistic regression analyses were carried out to identify demographic, health-related, psychosocial and care-related correlates of anxiety and depression. RESULTS: The prevalence of pure depression (PD) was 17.1%, of pure anxiety (PA) 4.8%, and of comorbid anxiety and depression (CAD) 5.1%. Comorbidity increased dependent on severity of both anxiety and depression. Different patterns of risk indicators were demonstrated for PA, PD and CAD for the investigated baseline characteristics. CONCLUSIONS: Comorbidity of anxiety and depression is most prevalent in the more severe depressive and anxious nursing home patients. The gradual increase of comorbidity of anxiety and depression dependent on the levels of severity of depression and anxiety suggests that for nursing home patients a dimensional classification of depression and anxiety is more appropriate than a categorical one. The observed differences in patterns of risk indicators for PA, PD and CAD support a distinguishing of anxiety and depression. Future studies are needed to assess the effect of treatment of PA, PD and CAD in nursing home patients.

The CIDI as an instrument for diagnosing depression in older Turkish and Moroccan labour migrants: an exploratory study into equivalence.

OBJECTIVE: The number of elderly migrants from Turkey and Morocco in Western Europe will increase sharply in the coming decades. Many of these migrants seem to have mental health problems. As mental health care programs are based on DSM criteria, there is a need for diagnostic instruments with good psychometric properties. This exploratory study examines the presence of construct bias, method bias and item bias in the Composite International Diagnostic Interview (CIDI) Basis Life time version 2.1 in elderly Turkish and Moroccan men and women. METHOD: From a community based health survey four groups of migrants aged 55-74 were selected for semi-structured interviews including the CIDI depression section. Data included interview transcriptions and observations of 11 respondents in each group (Turkish men, Turkish women, Moroccan men, and Moroccan women). The data were analysed using qualitative techniques. RESULTS: Construct bias, method bias and item bias of the CIDI was found in all groups. The poor match between the CIDI on the one hand and the taboo on mental health problems and the poor level of education of the respondents can partly explain this bias. CONCLUSIONS: The use of the CIDI in elderly migrants of Moroccan and Turkish descent is problematic, due to the presence of construct, method and item bias.
