Duration of neuroleptic treatment and prevalence of tardive dyskinesia in late life.

BACKGROUND: Although increasing age is the most consistently cited risk factor for the development of tardive dyskinesia for patients in the second to sixth decades of life, this relationship may not hold within geriatric populations. METHODS: Consecutively admitted geropsychiatric inpatients were examined with the Abnormal Involuntary Movement Scale within 72 hours of admission; comprehensive demographic, diagnostic, and psychometric data were also obtained. RESULTS: Seventy-four (19.2%) of 386 patients received diagnoses of dyskinesia. Lifetime duration of neuroleptic use was strongly correlated with dyskinesia rates. After accounting for the effect of lifetime duration of neuroleptic use in a stepwise logistic regression, only associations with Global Assessment Scale score and presence of dental problems remained statistically significant. In comparison with the duration of neuroleptic use, however, the contribution of these factors was minor. Sixteen percent of patients with less than 3 months of neuroleptic use, 29% with 3 to 12 months of neuroleptic use, 30% with 1 to 10 years of neuroleptic use, and 41% with more than 10 years of neuroleptic use had dyskinesia. Compared with patients with no history of neuroleptic treatment, the relative risks for these durations of neuroleptic use were 1.62 (95% confidence limits [CL], 0.81, 3.24), 2.89 (95% CL, 1.50, 5.55), 3.08 (95% CL, 1.66, 5.70), and 4.11 (95% CL, 2.12, 7.96), respectively. CONCLUSIONS: Within elderly populations, duration of exposure to neuroleptics is the strongest predictor of risk for tardive dyskinesia, and this risk increases rapidly within the first year of total lifetime neuroleptic use.

Medical comorbidity in elderly psychiatric inpatients.

A multidisciplinary diagnostic evaluation was performed for 868 older psychiatric inpatients during a 46-month interval. A total of 402 (46%) met DSM-III-R criteria for organic mental disorders, 329 (38%) had mood disorders, 90 (10%) had psychotic disorders, and 47 (5%) had other mental disorders or conditions. Concurrent medical problems were systematically assessed and classified according to ICD-9-CM criteria. The patients suffered from a mean of 5.6 +/- 3.1 (SD) active medical problems (range 0-18). This level of medical comorbidity was significantly greater than that of older psychiatric outpatients and comparable to that of elderly inpatients in general medical hospitals. When the effects of age and education were controlled for, there were no significant differences in mean numbers of medical problems among the four groups of psychiatric inpatients. An association of major depression with diseases of the digestive system was observed and may be related to peripheral autonomic dysregulation.

Impact of psychiatric hospitalization on behavioral complications of Alzheimer's disease.

OBJECTIVE: The authors conducted a prospective study of the clinical utility of the four DSM-III-R subtypes of primary degenerative dementia of the Alzheimer type (with delirium, with delusions, with depression, or uncomplicated) and acute psychiatric hospitalization for treatment of these subtypes. METHOD: The subjects were 120 consecutive inpatients with Alzheimer's disease, most of whom had behavioral abnormalities. Each subject received detailed physical, neurological, psychiatric, and mental status examinations. The presence or absence of specific behavioral problems was also documented. Patients were treated with medication, psychotherapy, and behavioral techniques. RESULTS: While all patients could be assigned to one of the four DSM-III-R behavioral subtypes, the uncomplicated subtype did not accurately reflect the burden of behavioral symptoms in the patients who did not have delirium, delusions, or depression. Each behavioral subtype responded in a characteristic way to inpatient treatment, as reflected by changes in scores on four psychometric scales used to assess cognitive impairment, psychiatric symptoms severity, and level of functioning at admission and at discharge, as well as by changes in residential setting following hospitalization. Half of all patients admitted from their homes and two-thirds of those with depression were able to go home following discharge. CONCLUSIONS: Behavioral syndromes in Alzheimer's disease should not be overlooked, because they have both clinical and prognostic significance. Short-term psychiatric hospitalization is effective and efficient for achieving the goal of returning patients to their homes and for safely implementing specific treatments in this frail population, and it may reduce the need for institutionalization.

Hopelessness in suicide attempters after acute treatment of major depression in late life.

The relation between hopelessness and suicide attempts in the elderly was examined by studying the course of hopelessness in depressed patients. Sixty-three elderly patients with recurrent major depression were treated with nortriptyline and interpersonal psychotherapy and underwent serial ratings of hopelessness and depression during the acute and continuation phases of treatment. Patients who had made a suicide attempt in the past had significantly higher hopelessness scores than nonattempters during both phases of treatment. They were also more likely to drop out of treatment. A high degree of hopelessness persisting after remission of depression in elderly patients appears to be associated with a history of suicidal behavior. It may also increase the likelihood of premature discontinuation of treatment and lead to future suicide attempts or suicide.

Impact of acute psychiatric inpatient treatment on major depression in late life and prediction of response.

OBJECTIVE: The authors conducted a prospective study to examine the sociodemographic and clinical characteristics of elderly inpatients with major depression and their response to acute psychiatric hospitalization. The relation between the descriptive variables and clinical response was also investigated. METHOD: The subjects were 205 consecutively admitted inpatients, whose mean age was 71 years, who met the DSM-III-R criteria for major depression. Each subject received detailed physical, psychiatric, and mental status examinations, along with quantitative assessments of psychiatric symptoms and cognitive performance at admission and at discharge. Management of physical problems was optimized, and patients were treated with a combination of somatic and psychotherapeutic interventions. The average duration of hospitalization was approximately 1 month. RESULTS: Despite considerable medical and psychiatric comorbidity, the patients responded well to treatment, as reflected by a 50% reduction in the average score on the Hamilton Depression Rating Scale. Nearly one-half of the patients had experienced the resolution of their depressive symptoms by the time of discharge. Race, cognitive performance at admission, number of medical problems, use of ECT, and length of hospitalization independently contributed to the prediction of clinical response. Response to treatment was not related to the other sociodemographic variables examined or to any of the indexes of severity of depressive episode. CONCLUSIONS: Short-term psychiatric hospitalization offers an effective and efficient vehicle for the treatment of severe or complicated cases of major depression in the elderly, even when considerable medical and psychiatric comorbidity is present.

Diagnostic rate of comorbid personality disorder in elderly psychiatric inpatients.

Among 547 elderly inpatients grouped by DSM-III-R axis I diagnoses, the diagnostic rate of comorbid personality disorder varied four-fold, from 6% in patients with an organic mental disorder to 24% in those with major depression. The previously reported low prevalence of comorbid personality disorder in geriatric patients may be due to its lower rate of diagnosis among patients with organic mental disorders.

Treatment of consecutive episodes of major depression in the elderly.

OBJECTIVE: The purpose of this study was to determine treatment outcome in elderly patients with consecutively treated episodes of recurrent unipolar major depression. METHOD: Subjects were 32 "young" elderly patients with recurrent unipolar depression (mean age = 66.8 years, SD = 5.1) and with two consecutively treated episodes of major depression. Both index and subsequent episodes of major depression were treated in open trial with combined nortriptyline and interpersonal psychotherapy. Rates of remission in index and subsequent episodes were compared by using nonparametric statistics and survival analysis with proportional hazards modeling. RESULTS: Of 30 patients who completed treatment of the subsequent episode, 27 (90%) achieved stable remission of symptoms in both consecutively treated episodes, whereas three patients (10%) did not. Twenty-two (81%) of 27 patients who responded to treatment had a shorter time to remission in treatment of the subsequent episode than in the index episode. Survival analysis with proportional hazards modeling detected a significant difference in time to remission of the index and subsequent episodes (32 paired observations). CONCLUSIONS: In this research study group, recurrent episodes of unipolar major depression in the young elderly were successfully treated to remission in over 80% of patients by using combined pharmacotherapy and psychotherapy similar to that employed in treatment of the index episode. Remission rate and time to remission in consecutively treated episodes were comparable to those in a group of midlife patients with recurrent depression reported by Kupfer et al. in 1989. Thus, recurrent depressive disorder appears to be as treatable in the young elderly as it is in midlife patients.

Combined pharmacotherapy and psychotherapy in the acute and continuation treatment of elderly patients with recurrent major depression: a preliminary report.

OBJECTIVE: The authors examined the rate of response to the combination of nortriptyline and interpersonal psychotherapy for acute and continuation treatment of elderly patients with recurrent major depression. METHOD: The subjects were 73 elderly patients, 61 of whom completed treatment. Nortriptyline steady-state blood levels were maintained at 80-120 ng/ml, and interpersonal psychotherapy was administered weekly for 9.1 weeks (medium) of acute therapy and was decreased from biweekly to triweekly during 16 weeks of continuation therapy. During acute treatment nonresponding patients also received brief adjunctive pharmacotherapy with lithium or perphenazine. RESULTS: Of the 61 subjects given adequate trials of nortriptyline and interpersonal psychotherapy, 48 (78.7%) achieved full remission (Hamilton depression rating of 10 or lower over 16 weeks of continuation therapy), 10 patients (16.4%) did not respond (Hamilton rating never below 15), and three achieved only partial remission (Hamilton rating of 11-14). Early versus late onset was not associated with a difference in response rate. During the placebo-controlled, double-blind transition to maintenance therapy, 19 (76.0%) of the 25 patients randomly assigned to placebo maintenance conditions showed continued recovery and six relapsed. None of the 24 patients assigned to nortriptyline conditions relapsed. CONCLUSIONS: Use of nortriptyline plus interpersonal psychotherapy for 9.1 weeks (median) of acute and 16 weeks of continuation therapy appears to be associated with good response and relatively low attrition but about a 25% chance of relapse during double-blind discontinuation of nortriptyline. These data require confirmation in a controlled clinical trial of acute and continuation therapy.

Schizophrenia in late life: elderly patients admitted to an acute care psychiatric hospital.

Although a considerable body of biological and clinical data has been accumulated on the mood disorders and organic disorders of late life, only a handful of studies have focused on aging schizophrenia patients. Using the results of a comprehensive evaluation of all elderly patients admitted over a 30-month period to a 26-bed acute care geriatric unit, we compared the demographic, social, and clinical characteristics of schizophrenia patients, patients with recurrent major depression with and without psychotic features, and patients with primary degenerative dementia of the Alzheimer's type with and without delusions. The main findings of this study are that elderly schizophrenia patients were younger, more often African-American, more often single, and poorer than the other groups. A concomitant history of substance abuse and institutionalization as an outcome were more frequent among schizophrenia patients. Like the older depressed and demented patients, schizophrenia patients were predominantly female and commonly presented with several medical disorders. The potential significance of these findings is discussed in the context of the literature on the long-term outcome of schizophrenia.

Dyskinesia and neuroleptic exposure in elderly psychiatric inpatients.

A wide variation in prevalence rates of tardive dyskinesia and spontaneous orofacial dyskinesia has been reported in the elderly. To clarify these discrepancies, we studied 45 patients over the age of 60 years admitted to a short-term psychiatric unit. Standardized criteria for the diagnosis of dyskinesia were used. We found a rate of tardive dyskinesia of only 21% (7/33) in our patients having a history of neuroleptic exposure. We found no cases (0/12) of spontaneous orofacial dyskinesia. There was a significant association between tardive dyskinesia and psychiatric diagnosis, with the highest rate of tardive dyskinesia in those patients with schizophrenic disorders, followed by those with organic disorders and mood disorders, respectively. There was also a significant association between the presence of tardive dyskinesia and radiographic evidence of cortical atrophy, and a trend towards an association with leukoencephalopathy. Our results suggest that published rates of tardive and spontaneous dyskinesia in the elderly may overestimate the prevalence of these disorders, especially among geriatric patients with acute psychiatric presentations.

Longitudinal analysis of nortriptyline side effects in elderly depressed patients.

Forty-five depressed elderly patients were closely monitored in a research setting during treatment with nortriptyline and interpersonal psychotherapy for 7 consecutive months of acute and continuation treatment. Overall, nortriptyline was efficacious and well tolerated in this group. The frequency of somatic complaints measured by the Rating Scale for Side Effects declined by 50% during the acute phase of treatment, suggesting that many somatic complaints that may be attributed to side effects of nortriptyline are actually somatic symptoms of depression. The authors discuss the implications of these findings and offer practical advice for the treating clinician.

Rating chronic medical illness burden in geropsychiatric practice and research: application of the Cumulative Illness Rating Scale.

Reliable quantitative ratings of chronic medical illness burden have proved to be difficult in geropsychiatric practice and research. Thus, the purpose of the study was to demonstrate the feasibility and reliability of a modified version of the Cumulative Illness Rating Scale (CIRS; Linn et al., 1968) in providing quantitative ratings of chronic illness burden. The modified CIRS was operationalized with a manual of guidelines geared toward the geriatric patient and for clarity was designated the CIRS(G). A total of 141 elderly outpatient subjects (two medical clinic groups of 20 each, 45 recurrent depressed subjects, 21 spousally bereaved subjects, and 35 healthy controls) received comprehensive physical examinations, reviews of symptoms, and laboratory testing. These data were then used by nurse practitioners, physician's assistants, and geriatric psychiatrists to compute CIRS(G) ratings of chronic illness burden. As hypothesized, analysis of variance demonstrated significant differences among groups with respect to total medical illness burden, which was highest among medical clinic patients and lowest in control subjects. Good interrater reliability (i.e., intraclass correlations of 0.78 and 0.88 in a subsample of 10 outpatients and a separate group of 10 inpatients, respectively) was achieved for CIRS(G) total scores. Among medical clinic patients, a significant correlation was found, as expected, between CIRS(G) chronic illness burden and capability as quantified by the Older Americans Activities of Daily Living Scale; and between CIRS(G) scores and physicians' global estimates of medical burden. Finally, with repeated measures of illness burden approximately 1 year from symptom baseline, significant rises were detected, as expected. The current data suggest that the CIRS(G) can be successfully applied in medically and psychiatrically impaired elderly subjects, with good interrater reliability and face validity (credibility).

Does recruitment method make a difference? Effects on protocol retention and treatment outcome in elderly depressed patients.

The specific aim of this study was to contrast effects of recruitment method (solicited, referred) on demographic, psychosocial, medical, and treatment outcome measures in an ongoing clinical trial of maintenance therapies in late-life depression. Data from 125 elderly patients (56 solicited via media campaign, 69 clinically referred) with recurrent, unipolar major depression were available for analysis. Several statistical contrast procedures, including group t tests, chi 2 tests, survival analysis, and logistic regression, were used to assess differences in patient profiles related to method of recruitment. Referred patients included a higher proportion of African Americans and had a lower level of education, fewer economic resources, and higher chronic medical burden. Solicited patients had been in the index episode longer than the referred patients at the time of protocol entry and were 3.4 times more likely to have experienced a "provoking agent" (severe life event or chronic difficulty) during the 6 months that preceded the onset of depressive symptoms. In contrast to these demographic and illness history differences, there were no differences in treatment response rates or time to response related to recruitment method. Solicited patients had an overall treatment response rate of 71% versus 62% in the referred group. Median time to response was 14.3 weeks in the solicited group and 13.6 weeks in the referred group. These results suggest that the inclusion of solicited patients in geriatric depression clinical trials does not bias short-term treatment outcome.

Biology of elderly suicide.

Most studies of suicide in younger patients have demonstrated significant alterations in the serotonin system. Although a high percentage of completed suicides occur in late-life, to date very few studies of the biology of suicide have focused on this age group. This chapter describes age-related changes in the central nervous system pertinent to the biology of suicide, then reviews post-mortem biological studies of the brains of suicides and suicide attempters. As suicide attempts in the elderly are characterized by the use of violent means, biologic studies of impulsive violence are discussed. Finally we describe data on the effect of degenerative diseases on the serotonin system and the possible link to increased suicidal behavior in affected patients. This review underscores the need for further study of the biology of suicide in the geriatric age group.

The relationship between patient, informant, social worker, and consensus diagnoses of personality disorder in elderly depressed inpatients.

Two psychiatrists simultaneously administered the Personality Assessment Form (PAF) to 20 depressed geropsychiatric inpatients and to 20 of their relatives (informants). A social worker also completed PAF ratings, and a consensus conference independently assigned an Axis II diagnosis. For patient interviews, categorical and dimensional interrater reliability indices for cluster and total personality disorders (PDs) were generally marginal. For informant interviews, categorical interrater reliability indices for cluster and total PDs were also marginal, but dimensional reliability was high. Consistent with previous research, agreement between categorical scores yielded by the four assessment methods was poor, but agreement between dimensional scores was generally better. It appears that patients, family members, and staff maintain different perspectives on patients' personality that, if overlapping, may provide useful diagnostic data.

Risk factors for white matter changes detected by magnetic resonance imaging in the elderly.

We found increased age (p = 0.001) and history or evidence of stroke (p = 0.016) to be significant independent multivariate predictors of the presence and severity of leukoencephalopathy on magnetic resonance imaging brain scans in a mixed population of 35 elderly psychiatric patients and 25 neurologically healthy elderly volunteers. These results suggest that subcortical ischemia, as well as age-related changes that may not be vascular in origin, contribute to the emergence of periventricular and other deep white matter hyperintensities that are commonly seen on the magnetic resonance imaging brain scans of older adults.

Ethnicity and psychopathology in an aging hospital-based population. A comparison of African-American and Anglo-European patients.

This study analyzes the effect of ethnicity, classified as African-American and Anglo-European, on diagnosis, symptomatology, and response to inpatient treatment in a sample of geriatric patients of a research unit of a tertiary care facility. Variables that might confound the effects of ethnicity, such as age, gender, education, and associated diagnoses, were statistically controlled. Psychotic diagnoses were significantly associated with ethnicity, being higher in African-Americans, weakening the claim that such an association stems from the confounding effects of social class. Variability in the ratings on the Brief Psychiatric Rating Scale and Hamilton Depression Scale was significantly associated with ethnicity in several instances. African-Americans appeared to obtain comparatively higher therapeutic benefits from hospitalization. Results are discussed using knowledge of the field of cultural and social psychiatry.

The Delirium Rating Scale in a psychogeriatric inpatient setting.

The Delirium Rating Scale (DRS) has been shown to be a valid instrument for identifying and grading the severity of delirium in patients admitted to a general hospital for medical or surgical treatment. However, its accuracy in identifying delirium among elderly patients admitted to a psychiatric hospital for evaluation and treatment of psychiatric illness has not been previously addressed. The DRS was administered to 791 elderly patients who were consecutively admitted to a psychogeriatric unit; 70 met DSM-III-R criteria for delirium. A DRS threshold score of > or = 10 correctly identified delirious patients with a sensitivity of 94% and a specificity of 82%. Both psychosis and cognitive impairment appeared to falsely elevate the DRS score in this population.

A naturalistic study of trazodone in the treatment of behavioral complications of dementia.

Altered serotonin transmission has been associated with behavioral complications of degenerative dementia. This study examined whether trazodone, a serotonergic antidepressant, may be useful in treating behavioral syndromes associated with dementia. Twenty-two dementia patients with behavioral problems were treated with trazodone (mean daily dose 172 ± 107 mg; mean duration 20 days). Seventy of cognitive impairment and behavioral symptoms were rated using the Mini-Mental State Examination (MMSE), the Global Assessment Scale, the Hamilton Rating Scale for Depression, and the Brief Psychiatric Rating Scale. A global assessment of improvement was made by chart review. Mean scores, with the exception of the MMSE, improved modestly but significantly between admission and discharge. Chart review of target symptoms revealed that 82% of the patients showed moderate-to-marked improvement on discharge, with most able to return to their preadmission residence. Trazodone was generally well tolerated except for occasional mild sedation effects. Results suggest that trazodone may be a useful alternative to neuroleptics or benzodiazepines in treating behavior problems in some demented patients.
