Sadness in older persons: 13-year follow-up of a community sample in Baltimore, Maryland.

BACKGROUND: Our prior psychometric work suggested that older adults interviewed in 1981 in a community survey were less likely than younger adults to report dysphoria. We hypothesized that this would also be true of older adults interviewed 13 years later. METHODS: This study is a population-based 13-year follow-up survey of community-dwelling adults living in East Baltimore in 1981. Subjects were the continuing participants of the Baltimore Epidemiologic Catchment Area Program. After excluding 269 adults who were 65 years of age and older at initial interview in 1981, 1651 adults remained (347 aged 65 years and older and 1304 who were 30-64 years-old at follow-up). We applied structural equations with a measurement model for dichotomous data (the MIMIC -- multiple indicators, multiple causes -- model) to compare symptoms between adults who were 65 years and older at follow-up with younger adults, in relation to the nine symptom groups comprising the diagnostic criteria for major depression, adjusting for several potentially influential characteristics (namely, gender, self-reported ethnicity, educational attainment, cognitive impairment, marital status and employment). RESULTS: Older adults were less likely to endorse sadness as evidenced by a direct effect coefficient of -0.335 (95% Confidence Interval -0.643, -0.027). After adjusting for several potentially influential characteristics, the direct effect of age was substantially unchanged (-0.298 (95% CI -0.602, 0.006)). CONCLUSIONS: Older adults in 1994, like older adults in 1981, were less likely to endorse sadness than younger persons. This finding suggests, but does not prove, that the observed age difference in reporting depression does not reflect a cohort effect.

Use of formal and informal sources of mental health care among older African-American public-housing residents.

BACKGROUND: Elderly residents of public housing have high rates of psychiatric disorders, but most of those in need of care do not use any mental health service. This study examines the use of formal and alternative informal sources of mental health care in a sample of elderly African-American public-housing residents. METHOD: Data from an epidemiological survey of six Baltimore public-housing developments for the elderly (weighted N = 818) were analysed to examine the utilization of mental health services by older African-American residents. Logistic regression analyses were used to determine correlates of using formal and informal sources by those needing mental health care. RESULTS: Thirty-five per cent of subjects needed mental health care. Less than half (47%) of those in need received any mental health care in the previous 6 months. Residents in need were more likely to use formal (38.5%) than informal sources (18.6%) for care. The strongest correlates of using formal providers were substance use disorder (OR = 15.62), Medicare insurance (OR = 10.31) and psychological distress (OR = 10.27). The strongest correlates of using informal sources were perceiving little or no support from religious/spiritual beliefs (OR = 21.65), cognitive disorder (OR = 19.71) and having a confidant (OR = 15.07). CONCLUSIONS: Contrary to elderly African-Americans in general, those in public housing rely more on formal than informal sources for mental health problems. Nevertheless, both sources fail to fill the gap between need and met need. Interventions to increase identification, referral and treatment of elderly public-housing residents in need should target general medical providers and clergy and include assertive outreach by mental health specialists.

Alcohol use disorder is a risk factor for mortality among older public housing residents.

Epidemiologic survey data were used to examine relationships between alcohol use and abuse and the physical and mental health status of elderly public housing residents (weighted n = 865) and to determine the influence that drinking behavior had on mortality. Residents with a current alcohol disorder (4%) were more likely to rate their physical health as fair/poor but had fewer major medical illnesses, functional impairments, and other current psychiatric disorders. Individuals with a current or past alcohol disorder (22%) were more likely than others to die (odds ratio [OR] = 7.5) during the 28-month follow-up period. In multivariate analyses, women with a past alcohol disorder were more likely than lifetime abstainers to die (OR = 21.9). Drinking behavior was not predictive of death in men. The high prevalence of alcohol disorder and its strong influence on mortality in this predominantly African-American female population demonstrate the need for programs designed to prevent and treat alcoholism in public housing developments for the elderly.

The caregiver's role in Alzheimer's disease.

The majority of persons with Alzheimer's disease (AD) are cared for by family members in their home. Research from several studies has shown that these care providers have rates of emotional morbidity three times that seen in age-similar individuals. This paper will review the epidemiological data on the incidence and prevalence of emotional disability in caregivers. It will also review the 11 treatment studies in the literature in which blinded intervention was carried out. Nine of these 11 studies show that intervention was more beneficial than the placebo comparison treatment. Both educational and emotional support were effective. However, when compared with each other, emotional support was more effective; the combination may be more effective than either alone. Preliminary evidence suggests that intervention on behalf of caretakers may delay the need for institutionalization of family members with AD.

Developing Treatment Guidelines for Alzheimer's Disease and Other Dementias.

Escalating health care costs and evidence that there is widespread variation in medical practice have led to the formation of more than 1800 consensus conferences in the past 10 years. These conferences seek to review the evidence that existing treatments have demonstrable efficacy; to determine if evidence favors one form of therapy over another; to review the guidelines for implementation, continuation, and discontinuation of the therapy; and to identify currently used treatments for which no benefit can be documented. This is a review of the process used by the American Psychiatric Association Task Force on Developing Treatment Guidelines for Alzheimer's Disease and Other Dementias, still in process at the time of this presentation.

Alzheimer's disease management.

The psychiatrist can play several important roles in the care of persons with Alzheimer's disease and other dementing illnesses. Diagnostic issues for which psychiatrists have specific skills include identifying early cases, performing a differential diagnosis, and distinguishing reversible depression from depression associated with irreversible dementia and irreversible dementia without depression. Treatment should include management of behavioral, noncognitive, and cognitive symptoms. Environmental and pharmacologic therapies have proven efficacious in treating noncognitive behavioral symptoms. Neuroleptic antipsychotic drugs are effective in treating aggressive behaviors and delusions. The treatment of cognitive symptoms currently rests on cholinergic enhancement. Finally, the psychiatrist can play important roles in educating the public and supporting the distressed caregiver.

Quantitative MRI volume changes in late onset schizophrenia and Alzheimer's disease compared to normal controls.

Volumes of medial and lateral temporal lobe structures were assessed using magnetic resonance imaging (MRI) in 11 patients with late-life onset schizophrenia (LOS), 18 normal elderly controls and 12 patients with moderate cognitive impairment due to Alzheimer's disease (AD) who had no non-cognitive symptoms. While both patient groups had smaller volumes of several medial temporal regions (e.g. entorhinal cortex, left hippocampus), schizophrenics had significantly smaller anterior superior temporal gyri (STG) than normal controls, but AD patients did not. We have previously demonstrated anterior STG volume to be reduced in early life onset schizophrenia.

Need and unmet need for mental health care among elderly public housing residents.

Epidemiologic survey data from elderly residents of six public housing developments were used to determine the prevalence of need and unmet need for mental health care. Thirty-seven percent of this predominantly African American sample needed mental health services, and 58% of those who needed care had unmet needs. Logistic regression analyses showed that males, older residents, those with no Medicare insurance, and those with more Activities of Daily Living (ADL) impairments were at greater risk of both needing mental health care and receiving no mental health care services. Findings suggest the need for targeted interventions that would increase service utilization and potentially reduce the likelihood of eviction or placement in more restrictive settings.

Depression without sadness: functional outcomes of nondysphoric depression in later life.

OBJECTIVES: We hypothesized that depressive symptoms not meeting full standard criteria for Major Depression would be associated with significant functional impairment among older adults over the course of a 13-year follow-up interval. Specifically, we developed criteria for a form of depression whose core symptoms did not include sadness or dysphoria. DESIGN: Population-based 13-year follow-up survey. SETTING: Community-dwelling adults living in East Baltimore in 1981. PARTICIPANTS: Subjects were the 1612 participants of the Baltimore sample of the Epidemiologic Catchment Area Program aged 50 years and older at the initial interview in 1981. MEASUREMENTS: The subjects were sorted into four categories based on their responses at baseline: (1) persons meeting standard criteria for Major Depression; (2) persons meeting alternative criteria for depression with dysphoria or (3) without dysphoria; and (4) a comparison category of persons not meeting any criteria for depression ("noncases"). The mortality and functional status of each group were compared after a 13-year follow-up interval. RESULTS: Compared with non-cases, participants aged 50 years and older who reported depressive symptoms but who denied sadness or dysphoria (nondysphoric depression) were at increased risk for death (relative risk (RR) = 1.70; 95% confidence interval (CI) (1.09, 2.67)), impairment in activities of daily living (RR = 3.76; 95% CI (1.73, 8.14)), impairment in instrumental activities of daily living (RR = 5.07; 95% CI (2.24, 11.44)), psychologic distress (RR = 3.68; 95% CI (1.47, 9.21)), and cognitive impairment (RR = 3.00; 95% CI (1.31, 6.89)) after a 13-year follow-up interval. The findings were not wholly explained by potentially influential baseline characteristics such as age, education, selected comorbid medical conditions, and functional status. CONCLUSION: Among adults aged 50 years and older, nondysphoric depression may be as important as Major Depression in relation to the development of functional disability and other long-term outcomes.

Risk of behavior problems among nursing home residents in the United States.

This study identified personal risk factors associated with behavior problems among nursing home residents using data based on a national survey of nursing home residents. Data are based on the Institutional Population Component of the 1987 National Medical Expenditure Survey and include nursing home residents living in licensed facilities on January 1, 1987. Multiple regression analyses were conducted to examine characteristics of residents that place them at risk of behavior problems. Independent variables include physical functioning, sensory impairment, cognitive impairment, psychiatric diagnoses, and demographics. Eleven behavior problems grouped into four categories based on factor analysis serve as dependent variables: wandering/safety, aggressive behaviors, collecting behaviors, and delusions/hallucinations. Risk factors emerging as predictors included sex (male), cognitive impairment, ADL dependency, incontinence, psychiatric history, receptive communication, walking, and difficulty seeing. Risk factors differ by type of behavior problem. Results suggest a multiple etiology in which biological, psychological, and sociocultural factors all play a role in generating behavior problems in the long-term care setting.

The 'research magnificent' in late life: psychiatric epidemiology and the primary health care of older adults.

OBJECTIVE: Primary care occupies a strategic positive in the evaluation, treatment, and prevention of the mental disturbances of later life. This article highlights four themes that are crucial to understanding mental disturbances among older adults: 1) subsyndromal depression, 2) coexisting depression and anxiety, 3) comorbidity of depression and chronic medical conditions, and 4) risk factors for cognitive impairment. METHOD: The literature was selectively reviewed for each theme to ask the central question, "What can primary care physicians learn about mental disturbances of their older patients from epidemiologic and community studies?" RESULTS: The primary care setting itself is an important venue for an examination of aging issues and mental health. Workers in the "middle ground of psychiatric epidemiology"--primary health care--have not yet reached a full appreciation for the value of research in the primary care setting for enhancing our understanding of the mental disturbances of late life, and how these intersect with other salient factors. CONCLUSIONS: Primary care physicians and others who work in primary care should advocate for further mental health integration and research in primary care. Research is needed that will lead to new ways of maximizing the health and quality of life of older adults and their families.

The prevalence of psychiatric disorders in elderly residents of public housing.

BACKGROUND: This study estimates lifetime and one-month prevalence of psychiatric disorders among elderly public housing residents. METHOD: Nine hundred forty-five residents of six public housing developments for the elderly were administered the General Health Questionnaire (GHQ), the Mini-Mental State Examination (MMSE), and the CAGE by lay interviewers. Residents screening positive and a 10% random sample of screen negatives were administered the Structured Clinical Interview for DSM-III-R (SCID) and a DSM-III-R derived algorithm for dementia and delirium. Prevalence rates were estimated based on weighted data from 298 subjects. RESULTS: Thirty-six percent of participants screened positive on at least one instrument. Based on the case identification interview, estimated lifetime prevalence of psychiatric disorders was 57.6%, and one-month prevalence was 27.9%. Cognitive disorder (10.5%), mood disorder (8.0%), psychotic disorder (4.6%), and substance abuse/dependence (4.4%) were the most common current disorders. Mood disorders (26.6%) and substance abuse/dependence (23.0%) were the most prevalent lifetime disorders. Compared to data from the Epidemiologic Catchment Area, public housing residents have higher current rates of mood disorder, schizophrenia, and substance use disorder. CONCLUSIONS: Elderly residents of public housing suffer higher rates of psychiatric morbidity than older people living independently in the community. The high prevalence of psychiatric disorders in this growing population of low-income elderly presents a challenge to the delivery of mental health service.

Developing treatment guidelines for Alzheimer's disease and other dementias.

Developing treatment guidelines for Alzheimer's disease and other dementias depends primarily on a literature review. A recent review suggests that tacrine is modestly effective in treating cognitive symptoms and that-neuroleptic drugs are modestly effective in treating agitation and aggression. Few randomized, double-blind, placebo-controlled trials of other agents used for the treatment of cognitive and noncognitive symptoms of dementia have been performed. A variety of behavioral/environmental interventions show modest but nonspecific effects in treating Alzheimer's disease and other types of dementia. Family-focused support interventions are moderately effective and may delay nursing home placement.
