Disability and cognitive impairment show similar patterns of increasing frequency with ageing. A review of the published literature shows that there is a cross-sectional relationship between cognitive impairment and disability, independent of demographic, medical, and lifestyle factors. Some instrumental activities of daily living (IADL) items appear more specifically related to cognitive impairment, but cognition and functional impairment are distinct concepts requiring separate assessments. Subjects with low cognitive performances are at higher risk of functional impairment in the following years. Cognitive impairment as well as disability increase the risk of death and institutionalization. Preventive strategies could be directed against the risk factors of cognitive impairment and disability, and would aim to delay the onset of dementia. Prevention of disability associated with cognitive impairment needs further assessment in elderly community-dwellers. Further research is needed to better identify the specific areas cognition involved in the disablement process. 相似文献

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. 相似文献

OBJECTIVE: The purpose of this study was to determine if P300 latency is prolonged in geriatric depression and if longer P300 latency and deficits in initiation and errors of perseveration in depressed elderly patients are related to risk factors for vascular disease. METHOD: Geriatric patients with unipolar depression (N = 43) and elderly comparison subjects (N = 24) were assessed for depressive symptoms, cognitive functions, risk factors for vascular disease, and P300 latency. RESULTS: Depressed elderly patients had longer P300 latency than normal elderly subjects. In the depressed patients, P300 latency was related to deficits in initiation and errors in perseveration. Risk factors for vascular disease were associated not only with P300 latency but also with deficits in initiation and errors in perseveration. CONCLUSIONS: Functional impairment of the cortico-striato-pallido-thalamo-cortical pathways from vascular disease, implicated in late-life depressive disorders, may explain not only deficits in initiation and errors in perseveration but also longer P300 latency in depressed elderly patients. These results are preliminary and need further examination with brain imaging and more sensitive neuropsychological measures. 相似文献

BACKGROUND and PURPOSE: Stroke is a major cause of disability in the elderly and is also related to the development of dementia, which is another important source of disability in old age. The aim of the present study was to examine the potential impact of stroke on cognitive and functional status in a community-based cohort of individuals aged 75 years and older. METHODS: The data were derived from a cross-sectional survey on aging and dementia that included all inhabitants of the Kungsholmen district in central Stockholm who were aged >/=75 years. Cases of stroke were identified through the computerized inpatient register system that has been widely used to study stroke in Sweden. Dementia was defined according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. Dementia onset was considered the appearance, according to an informant, of the first symptom. Cognitive impairment without dementia was defined as the presence of a Mini-Mental State Examination score of <24 and the absence of dementia. Functional disability was assessed according to Katz Index of independence in activities of daily living. RESULTS: The prevalence of stroke was 10. 0% in men and 8.0% in women. One third of stroke survivors were diagnosed as demented, which was 3 times higher than those without stroke: adjusted odds ratio (OR) was 3.6 (95% confidence interval, 2. 5 to 5.8). Stroke was also significantly related to cognitive impairment without dementia (adjusted OR, 2.4 [95% confidence interval, 1.3 to 4.6]). The population-attributable risks of dementia and cognitive impairment in relation to stroke were 18.4% and 8.5%, respectively. Among the 49 stroke patients with dementia, 15 cases (30.6%) had missing information on dementia onset, 22 (44. 9%) had been reported by the informant to have dementia-related symptoms after or close to the occurrence of stroke, and 12 (24.5%) had symptoms before stroke occurrence. The prevalence rates of disability in activities of daily living were much higher among stroke patients than among stroke-free subjects, even after adjustment for age, sex, heart disease, hip fracture, and dementia: the corresponding adjusted ORs for bathing, dressing, toileting, transfer, and continence were 3.5 (2.4 to 5.3), 2.2 (1.4 to 3.3), 3. 0 (2.0 to 4.5), 3.3 (1.9 to 5.7), and 2.1 (1.3 to 3.3), respectively. After dementia and hip fracture, stroke was the third largest contributor to disability in bathing, dressing, and transfer. Stroke was the second contributor to disability in toileting. CONCLUSIONS: Stroke is strongly associated with dementia, although it may relate to dementia in different ways: it can be the main cause or a precipitating factor of dementia, or they may share common etiological bases. Together with dementia and hip fracture, stroke is a major contributor to disability in most aspects of activities of daily living in very old people. 相似文献

OBJECTIVE: To evaluate the relationship between change in depressive symptoms and in-hospital physical rehabilitation in elderly women. DESIGN: Longitudinal study. SETTING: Hospital facility (geriatric evaluation and rehabilitation unit). PATIENTS: One hundred twenty-three elderly inpatient women (mean age: 78.4+/-6.9 years, range 60 to 93) with good cognitive status (Mini Mental State Examination: 23.1+/-5.1) consecutively admitted over a 7-month period. INTERVENTION: Physical therapy tailored to individual needs (five sessions a week of 30 to 45 minutes each). MAIN OUTCOMES MEASURES: On admission: cognition (MMSE), depressive symptoms (Geriatric Depression Scale [GDS]), functional status (basic and instrumental activities of daily living [BADL, IADL], Tinetti scale), and somatic health. On discharge: depressive symptoms and gait and balance performances (Tinetti scale). RESULTS: Seventy-five patients (61%) did not show changes on Tinetti scale over the hospitalization period and 48(39%) had a change of 3 or more points. Nonresponders had no change of GDS over the hospitalization period for all levels of physical disability on admission, whereas responders had relevant improvement of depressive symptoms when markedly disabled on admission, and progressively smaller improvements of depressive symptoms with increasing function on admission. CONCLUSIONS: The study provides evidence that mood status changes synchronically with disability. 相似文献

This report documents cases of suicide attempts by two persons with Down's syndrome. The patients experienced dysphoric affect and feelings of hopelessness about unmet needs associated with their disability. During the course of a major depressive episode, each individual made a suicide attempt that could have been fatal. Although suicidal ideation and attempts are infrequent among patients with mental retardation, completed suicides and potentially fatal attempts have been reported. It is vitally important that mental health practitioners appreciate the seriousness of suicidal ideation among persons who have mental retardation and treat the underlying psychiatric disorder. 相似文献

We studied semantic priming in 20 major depressive subjects. The methodology used was a visual lexical decision task. Semantic priming is the facilitation of target word recognition (shortening of response time) by the prior presentation of a semantically related context (a prime word). It relies on semantic processing of words and context, facilitating early cognitive stages of response. Varying the temporal interval between prime and target words onset allows us to distinguish between two priming mechanisms, relying on more automatic (test 1) or more controlled (i.e. attention dependent) (test 2) information processing. We observe a significant retardation for words and pseudo-words in depressives (in relation to controls) in both tests. In spite of a general retardation and increase of response times in depressives, semantic priming is evident in both groups and both tests, and does not differ significantly between depressive and control groups in either automatic or controlled conditions. Theses results confirm that semantic processing is not impaired in depression, and are discussed with regard to the hypothesis of an effortful processing impairment in depression, and to depressive retardation. 相似文献

OBJECTIVE: The authors tested the hypotheses that medical illness burden is independently associated with depression and that this association is moderated by neuroticism. METHOD: Multiple regression techniques were used to determine the independent associations of medical burden and neuroticism with depression in a group of 196 subjects, 60 years of age and older, recruited from primary care settings. RESULTS: Medical burden and neuroticism were independently associated with major depression, depressive symptoms, and psychiatric dysfunction. CONCLUSIONS: These findings support models in which medical disorders may contribute directly to depression. At the same time, the role of neuroticism in later-life depression warrants further study. 相似文献

Declines in chronic disability were observed in the National Long Term Care Survey (NLTCS) 1982 to 1994. We analyzed the 1982, 1984, 1989, and 1994 NLTCS to identify the dimensions of chronic disability from multivariate analyses of a rich battery of measures of the ability (or inability) to perform specific activities. Changes over time in the prevalence of individual disability dimensions can be tracked to evaluate the rate of age-related losses of specific functions, 1982-1994. Seven dimensions described changes in the age dependence of 27 activities of daily living, instrumental activities of daily living, and physical performance measures in community and institutional resident elderly individuals over the 12 year period. Adjusted for age, the healthiest dimension with the best physical function experienced the largest increase in prevalence (3.3%) implying a decline in age-related disability. Disability declines were correlated with reductions in select health conditions (e.g., dementia and circulatory disease) over the study period. 相似文献

A survey of UK medical schools was undertaken to determine the teaching that was being offered on disability and rehabilitation. In general, teaching on this topic appeared fragmented and inadequate but a number of interesting innovations were identified. These included: a drama workshop run by a group whose members mainly have learning disabilities at St George's Medical School, student-directed learning at the University of Dundee and structured teaching programmes at the Universities of Leeds and Edinburgh. The General Medical Council Education Committee's 1991 discussion document on the undergraduate curriculum specifically mentions disability as an important topic. A number of schools mentioned that they were in the process of revising their curriculum as a consequence. Recommendations arising from the findings of the survey include integration of disability and rehabilitation into clinical teaching, focus of teaching on those types of disability which are common in the community, greater emphasis on functional assessment in teaching the physical examination, and the wider use of standard assessment instruments, for example for activities of daily living, cognitive impairment and locomotor disability. There is a need for improved communication between medical schools to facilitate the spread of educational activities on this topic. 相似文献

The degree of long-term (7.41 yrs postinjury) impairment of disability awareness was quantified in 63 adults (aged 18–45 yrs) with closed-head injuries as the difference between self-ratings and staff ratings on the Scales of Independent Behavior. Other measures included the Wechsler Adult Intelligence Scale--Revised (WAIS--R), the Wechsler Memory Test—Revised, the Wisconsin Card Sorting Test, and ratings of actual functional status based on classifications in vocational and independent living level. Impaired awareness and its relationship to actual level of present vocational and residential status, maladaptive behaviors, attention and freedom from distractibility, and a measure of frontal system functioning was examined. Impaired awareness was significantly associated with lower vocational and residential status, maladaptive behavior, greater distractibility, and increased perseveration. Impaired awareness is directly proportional to duration of posttraumatic amnesia and general memory. Impaired awareness of disability appears to be a consequence of a general cognitive impairment rather than a specific deficit. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This study tested whether history of depression is associated with an increased likelihood of dementia, and whether a first depressive episode earlier in life is associated with increased dementia risk, or whether only depressive episodes close in time to dementia onset are related to dementia. Depression information came from national hospital discharge registries, medical history, and medical records. Dementia was diagnosed clinically. In case–control results, individuals with recent registry-identified depression were 3.9 times more likely than those with no registry-identified depression history to have dementia, whereas registry-identified depression earlier in life was not associated with dementia risk. Each 1-year increase in time between depression onset and dementia onset or equivalent age decreased the likelihood of dementia by 8.4%. In co-twin control analyses, twins with prior depression were 3.0 times more likely to have dementia than their nondepressed twin partners, with a similar age of depression gradient. These findings suggest that after partially controlling for genetic influences, late-life depression for many individuals may be a prodrome rather than a risk factor for dementia.

BACKGROUND AND OBJECTIVES: This study evaluated the reliability and validity of the Patient-Caregiver Functional Unit Scale (PCFUS), a new instrument to assess the stability or endurance of patient-caregiver dyads. METHODS: Patient-caregiver dyads were recruited from a nursing home (NH) (n = 38), a comprehensive geriatric assessment program (CGA) (n = 20), and an ambulatory medical clinic (controls) (n = 85). Caregivers were eligible if they assisted, or were available to assist, the patient with personal and instrumental activities of daily living, without pay. Data were collected by interviewer-administered questionnaires. Inter-rater and test-retest reliability were evaluated among the CGA sample. Validity was assessed by comparing PCFUS scores among the NH, CGA, and control groups and by correlation of PCFUS scores with other standardized caregiver burden measures. RESULTS: The PCFUS had excellent inter-rater and test-retest reliability. Mean PCFUS scores were significantly lower (ie, less stable patient-caregiver dyad) in NH than CGA and control caregivers. PCFUS scores were significantly associated with Burden Interview, Perceived Stress Scale, and Geriatric Depression Scale scores and risk factors for caregiver stress (eg, patient's cognitive impairment, disruptive behaviors). CONCLUSIONS: The PCFUS is a short, easily administered measure with good reliability and validity and is applicable to clinical and research settings. 相似文献

Three hundred thirty-eight community dwelling, ambulatory, elderly patients who sustained a hip fracture were observed prospectively to determine which patient and fracture characteristics at hospital admission predicted functional recovery at 3, 6, and 12 months. Multiple logistic regression was performed to estimate the simultaneous contributions of the predictor variables to failure of functional recovery. Before sustaining a fracture, 16% of patients were dependent on basic activities of daily living and 46% were dependent on instrumental activities of daily living. By 1 year after fracture, 73% of the patients had recovered to their basic activities of daily living status before fracture whereas only 48% had recovered to their instrumental activities of daily living status before fracture. Patients who were age 85 years or older, who lived alone before sustaining a fracture, and who had one or more comorbidities were at increased risk of delay or failure in recovering basic activities of daily living. Only instrumental activities of daily living independence before fracture predicted failure to recover instrumental activities of daily living function by 3 and 6 months after fracture. At 1 year, patient age 85 years or older was the only predictor of failure to recover instrumental activities of daily living function that existed before fracture. Based on characteristics at admission, a group of patients at high risk for failure to recover basic activities of daily living function within 1 year of sustaining a hip fracture can be identified. 相似文献

The relations among physical functioning, social support, depressive symptoms, and life satisfaction were examined in a national sample of 4,734 adults age 65 and older. Regression analyses were used to examine the relative importance of objective and subjective support measures in understanding the relation between physical impairment and quality of life. Impairment was associated with fewer friendship contacts, fewer family contacts, less perceived belonging support, and less perceived tangible aid, but only measures of perceived support predicted depressive symptomatology. A structural equation modeling approach was then used to explore the mediational role of perceived social support in the relation between impairment and quality of life variables. Results are consistent with the hypothesis that lower reported social support is an important reason for decreases in life satisfaction and increases in depressive symptoms found among older adult populations. Implications for understanding the role of social support in attenuating the effects of physical disability in older adults are discussed.

To examine the correlates of dependent living after ischemic stroke, a consecutive cohort of 486 patients aged 55-85 years was examined 3 months after the index stroke. Detailed medical, neurological and radiological stroke evaluation, structured measures of cognition, emotion and behavior, activities of daily living (ADL), physical disability, and assessment of dependent living were performed. Independent correlates of dependent living 3 months after stroke were the presence of the major hemispheral stroke syndrome (odds ratio, OR, 11.8, 95% confidence interval, CI, 7.2-19.9), and a combination of handicap (Rankin Scale, OR 3.9, 95% CI 2.6-6.1), cognition (DSM-III-R dementia, OR 3.9, CI 1.5-10.7, any cognitive decline, OR 4.5, CI 2.0-11.2), and ADL [Functional Activities Questionnaire (FAQ), OR 1.2, 95% CI 1.1-1.2]. The Rankin Scale explained 51.5%, FAQ 5.9% and presence of DSM-III-R dementia or any cognitive decline 3.4% of the total variance between dependent and independent patients after stroke. Independent of the effects of physical disability, presence of cognitive impairment has important functional consequences on stroke patients. Our findings emphasize the importance of the evaluation of cognitive functions in both observational and interventional clinical trials, as well as in treatment planning, rehabilitation and guidance of patients with ischemic stroke. 相似文献

This study examined the degree to which demographic variables, psychiatric diagnosis, depression rating, and neuropsychological test performance predict adaptive kitchen behavior in geriatric psychiatry patients and normal elderly volunteers. Amixed group of 27 participants including 8 normal volunteers and 19 geriatric psychiatry inpatients underwent psychiatric evaluation, neuropsychological testing, and a kitchen skills assessment conducted in a natural setting. Both depression and dementia were prevalent among patients. The kitchen skills assessment was abnormal in 69% of patients, compared to none of the normal volunteers. Estimated premorbid IQs, psychiatric diagnosis, and neuropsychological test scores significantly predicted the pass/fail status on the kitchen skills assessment, but there was no effect for age, education, gender, or depression. The discriminant function analysis classified 92% of cases, and the canonical correlation coefficient was .84. Of the neuropsychological tests employed in the study, two tests involving visuospatial processing and attention were retained in the discriminant function analysis. The results are consistent with previous studies that suggest that visuospatial tasks are more predictive of instrumental activities of daily living than are cognitive tasks emphasizing verbal and memory abilities. In addition, we conclude that neuropsychological test data are useful and valid for the purpose of guiding clinical judgments regarding activities of daily living in geriatric psychiatry patients. 相似文献

Relationships between demographic-, treatment-, and sickness-related factors, metabolic control (HbA1c), perceived burden of illness, and degree of depressive symptoms were examined in a group of 155 insulin-dependent diabetic patients, aged 35.3 +/- 8.9 years. The patients completed a questionnaire measuring depressive symptoms and three aspects of perceived burden of illness. No gender differences in HbA1c level or occurrence of late diabetic complications were found. Both men and women showed a modestly elevated degree of depression compared with norm groups. Self-reported burden of illness was strongly related to depression but was largely unrelated to objective disease-related measures. Level of depression was correlated neither with degree of metabolic control nor with the presence of such late diabetic complications as retinopathy and nephropathy. Some 44% of the variance in depression could be explained by worries about complications in those patients with the lowest HbA1c levels, by perceived restrictions in everyday life in patients with intermediate metabolic control, and by problems of glycaemic regulation in patients with poor metabolic control. Degree of depression was largely unrelated to disease severity, but was found to be related to the perceived daily burden of living with the disease, the specific worries and concerns associated with a depressed mood varying with degree of metabolic control. 相似文献

BACKGROUND: A growing number of dependent elderly people is cared for at home by family members. However, long-term caregiving may become an intolerable strain for some families and lead to failure of family care. The aim of the study was to examine if level of physical and mental disability of the patient influences the extent of perceived caregiver burden representing risk factor for negative outcome. METHODS AND RESULTS: 128 elderly patients with disability and dependency (37 men, 91 women, average age 79.9 +/- 6.9 yrs) and 128 their primary caregivers, mostly family members (28.9% men, 71.1% women) were evaluated. Functional status of care recipient was assessed by means of Barthel ADL Index (mean = 70.9 +/- 26.5), IADL Test (mean = 31.4 +/- 23.5) and Mini-Mental State Exam, MMSE (mean = 20.4 +/- 6.5). Average score of Caregiver Burden Interview (CBI) was 34.7 +/- 18.8. According to CBI, 40.6% of caregivers were found under high or even extremely hig level of stress. Level of perceived burden correlated significantly with physical and mental disability level, in decreasing order for IADL, ADL and MMSE (rs = 0.582-0.708, p < 0.001). CONCLUSIONS: Caregiver burden of family caregivers is significantly related to the level of functioning and cognitive impairment of care recipient, particularly to his/her ability to perform instrumental activities. Functional decline of elderly patient represents a risk factor which contributes to negative caregiving outcome and institutional placement. 相似文献

OBJECTIVES: Many reports indicate that patients with combined chronic illness and depressive symptomatology have more disability than those with illness alone, which may influence physician visits. Studies suggest that these combined conditions are unevenly accommodated by the delivery system and nonpsychiatric physicians often fail to recognize or treat these symptoms. To address this need, this study aimed to provide further information on combined conditions and report on relations found among arthritis disease symptoms, depression, and disability. METHODS: The data was derived from a series of statewide surveys assessing the influence of psychosocial factors on disease course and treatment in a community sample of 277 patients under the care of a rheumatologist. A multivariate model was developed to assess these interrelationships, using measures of symptom severity, depression (CESD), disability (activities of daily living, days of restrictive activities, days in bed), service utilizations, and a few personal and health variables. RESULTS: Even after removing somatic items from the CESD to reduce the risk of inflation due to physical disease, evidence was found for additive impact of depression on one measure of disability, days of restrictive activities. Patients with comorbid conditions also were a high-service utilization group. Very few patients reported receiving help in dealing with emotional problems, suggesting presence of substantial unmet need. CONCLUSIONS: Nonpsychiatric physicians need to be aware of the mental health status of chronically ill patients. Although the association between medication use and depression suggests some awareness of the need to treat depression, especially in physically compromised patients, there may be some need to dispense psychological and psychosocial support to those in need. 相似文献
