Correlates of psychotic symptoms among elderly outpatients.

Psychotic symptoms presenting in late life can offer a diagnostic challenge to the clinician. In this study, 140 geriatric outpatients were prospectively examined for psychotic symptoms and assessed on a number of demographic and clinical variables. Cognition was assessed using the Mini-Mental State Exam. Psychiatric diagnoses were made by DSM-III-R criteria. Twenty-seven per cent (N = 38) had psychotic symptoms, delusions being the most common type. Patients with psychosis were significantly more likely to have a previous history of psychosis, to have a lower MMSE and to live in a nursing home. Four diagnoses accounted for 79.5% of all psychotic patients. In order of frequency, these were dementia, major depression, delirium and organic psychosis (organic hallucinosis, organic delusional disorder). Psychotic patients were significantly more likely to have a diagnosis of dementia, delirium or organic psychosis than non-psychotics, but depression was significantly more likely to occur in patients without psychosis. Although psychotic symptoms occur in a variety of illnesses, elderly patients with psychosis should be carefully evaluated for these disorders.     

Diagnosis of physical illness in psychiatric patients using axis III and a standardized medical history.

Psychiatrists' axis III diagnoses of physical illnesses in 357 psychiatric patients were compared with diagnoses by a physician's assistant using a standardized medical history form. The physician's assistant detected nearly three times as many physical illnesses as the psychiatrists. The psychiatrists were significantly more likely to miss diagnoses among older patients and women. Patients who met criteria for depressive disorders appeared to be at greatest risk for undetected illnesses, followed by patients with bipolar disorders and schizophrenia. Patients with a secondary diagnosis of substance abuse had significantly more undetected illness than those who did not abuse substances. The authors suggest that current axis III guidelines are inadequate and that a systematic review of physical health problems should be part of the psychiatric diagnostic assessment.     

Hospitalization of patients with cocaine and amphetamine use disorders from a psychiatric emergency service

OBJECTIVES: Among the illicit stimulants, cocaine and amphetamines are the most widely abused. Although these drugs have similar psychoactive properties and routes of administration, their duration of action and mechanism of action are different, as are the psychiatric problems that accompany their use. The authors explored whether these differences and results of urine drug testing were associated with differences in use of psychiatric inpatient services. METHODS: The records of 2,357 patients admitted to a large county psychiatric emergency service were examined to determine whether patients admitted for amphetamine-related or cocaine-related disorders differed in rates of transfer to an inpatient psychiatric ward or in length of stay on the ward after transfer. The authors also examined whether positive or negative results of urine drug screens predicted transfer or length of stay. RESULTS: Patients with amphetamine-related disorders were more than a third more likely than patients with cocaine-related disorders to be transferred to the inpatient ward. Patients with negative urine screens were a third more likely than those with positive screens to be transferred and stayed slightly longer on the ward after transfer. Patients with cocaine-related disorders stayed slightly longer on the ward than patients with amphetamine-related disorders. CONCLUSIONS: Patients with amphetamine-related disorders have higher rates of psychiatric hospitalization than patients with cocaine-related disorders. Diagnostic uncertainty and other factors may also influence transfer rates and subsequent length of stay.     

Effects of diagnosis and context on dangerousness

The authors extensively reviewed the medical records of 253 patients hospitalized on a locked, university-based psychiatric unit. They found that schizophrenic and manic patients were more likely than patients with other diagnoses to be assaultive before admission. In the hospital, however, manic patients were the most likely to be assaultive. The results of this study show that the risk of violence among different diagnostic groups of patients varies according to context and is moderated by situational variables. These findings have implications for the assessment of dangerousness before and during hospitalization.     

Unexplained fatigue syndromes in a multinational primary care sample: specificity of definition and prevalence and distinctiveness from depression and generalized anxiety

OBJECTIVE: The authors investigated whether narrow definitions of unexplained fatigue syndromes that require additional minor somatic symptoms are more strongly associated with psychiatric morbidity than wider ones. METHOD: This was a secondary analysis of the World Health Organization Collaborative Project on Psychological Problems in General Health Care. A total of 5,438 primary care patients from 14 countries were assessed with the Composite International Diagnostic Interview. RESULTS: The prevalence of fatigue syndromes fell from 7.99 to 1.69 as somatic criteria were added. Patients with depression or anxiety were more likely to report unexplained fatigue, but this association was stronger for definitions of unexplained fatigue with more somatic criteria. CONCLUSIONS: Definitions of unexplained fatigue syndromes that require more somatic criteria selected more patients with psychiatric disorders in this culturally diverse sample. These findings might have implications for the revision of existing international diagnostic criteria for neurasthenia or chronic fatigue syndrome.     

Memory complaints and memory deficits in young and old psychiatric inpatients

Memory complaints and memory deficits were investigated in 206 consecutively admitted psychiatric inpatients at the University of Iowa Psychiatric Hospital. Forty-five percent of patients over age 60 years and 29% of patients less than 60 years old had severe memory complaints. Patients with complaints of memory loss were no more likely than patients without such complaints to have a memory deficit. In patients over age 60 years, memory complaint was more common in depression than in dementing and amnestic disorders (73% v 43%), while in younger patients memory complaint was slightly more common in dementing and amnestic disorders than in depression (57% v 41%). Increasing age was significantly correlated with increasing likelihood of memory complaint for depressed patients but not for nondepressed patients. As a result of these findings, memory complaint was found to be a statistically significant marker for depression in the elderly (sensitivity = 73%, specificity = 75%) but not in younger patients. Our results confirm the clinical observation that memory complaints are a useful marker for depressed states in the elderly.     

Personality disorders and treatment outcome in the NIMH Treatment of Depression Collaborative Research Program

The authors investigated the relationship between personality disorders and treatment outcome in the National Institute of Mental Health Treatment of Depression Collaborative Research Program, which involved 239 outpatients with major depressive disorder randomly assigned to one of four 16-week treatment conditions. Patients with personality disorders (74% of the sample) had a significantly worse outcome in social functioning than patients without personality disorders and were significantly more likely to have residual symptoms of depression. There were no significant differences in work functioning or in mean depression scores at treatment termination. Outcome was similar for patients in the different clusters of personality disorders.     

Treatment of patients with no diagnosable mental disorders in CMHCs

Community mental health centers (CMHCs) have been criticized for directing resources that should be used to treat the seriously mentally ill to the treatment of less impaired patients. Many of the latter group are assigned one of the DSM-III V codes for conditions that do not meet criteria for a mental disorder. This study compared patients with V-code conditions and those with diagnosed mental disorders on clinical, social, and economic variables. V-code patients were significantly less likely to have had prior care and to rely on third-party payments. They were significantly more likely to have been self-referred or referred by friends or family and to be white, well-educated, female, and married. CMHCs that treated fewer V-code patients reported proportionally more staff hours worked by physicians, indicating a greater medical orientation. The authors believe CMHCs should periodically evaluate whether, by serving patients with less serious conditions, they are diverting badly needed resources away from the seriously mentally ill.     

Frequency and clinical features of suicide attempts in elderly patients in Japan

The objective of this study was to investigate the clinical features of suicide attempts in elderly patients (≥65 years) in Japan. We enrolled 546 patients who attempted suicide and were hospitalized for inpatient treatment. Characteristics were compared between the elderly and non‐elderly patients. Compared with the non‐elderly group, the incidence of mood disorders was significantly higher and the average length of stay in the intensive care unit and the duration of hospitalization were significantly longer in the elderly group. Elderly patients hospitalized for attempted suicide were more likely to have mood disorders than the non‐elderly.     

The dangerousness criterion for civil commitment: the problem and a possible solution

The dangerousness criterion for civil commitment fails to specify which mental disorders justify commitment. This ambiguity is highlighted by the fact that there are patients with personality disorders or substance abuse who may be dangerous but for whom we have few effective treatments. A possible solution might be provided by adopting the American Psychiatric Association guidelines which consider severity of mental disorder and treatability in its criteria.     

Parens patriae considerations in the commitment process

Seventy-one commitment-seeking decisions made by 36 clinicians in a state-funded mental health center were studied to determine the extent to which clinicians attend to legally mandated "dangerousness" criteria in seeking commitment. A previous finding that clinicians rely largely on the dangerousness criteria was replicated. In addition, clinicians were found to be sensitive to clinical indicators of the patient's need for treatment, a question which is central to the parens patriae approach to involuntary hospitalization. Further, patients who were judged to be more seriously ill or more dangerous were more likely to retract their requests for discharge. This finding suggests that the patient's request for release and the psychiatrist's petition for commitment together constitute an interactive, transactional process in which the clinician's and the patient's views of the patient's need for hospitalization influence each other.     

Treatment outcome in suicidal vs. non-suicidal elderly patients.

The authors investigated treatment outcome in elderly suicidal and non-suicidal patients with recurrent major depression. Patients without suicidal ideation in the current episode (Non-Ideators; n=150) were compared with 30 patients who expressed suicidal ideation (Ideators). Patients received combined pharmacotherapy and psychotherapy during acute and continuation treatment. Ideators had higher numbers of lifetime suicide attempts and reported significantly higher levels of depression, anxiety, and hopelessness before starting treatment. Ideators and Non-Ideators had almost identical remission rates (77% vs. 78%), but Ideators had higher relapse rates during continuation treatment (26% vs. 13%) and were more likely to receive augmentation pharmacotherapy. Anxiety and use of adjunctive medication, but not suicidal ideation, were negatively related to both remission and relapse. Our data suggest that elderly suicidal patients have an overall favorable treatment outcome. However, treatment response may be more brittle and may require the continuing use of adjunctive medications to prevent early relapse.     

Attention and fluctuating attention in patients with dementia with Lewy bodies and Alzheimer disease

BACKGROUND: Attentional deficits are described in the consensus clinical criteria for the operationalized diagnosis of dementia with Lewy bodies (DLB) as characteristic of the condition. In addition, preliminary studies have indicated that both attentional impairments and fluctuation of attentional impairments are more marked in patients with DLB than in patients with Alzheimer disease (AD), although neuropsychological function has not previously been examined in a large prospective cohort with confirmed diagnostic accuracy against postmortem diagnosis. METHODS: A detailed evaluation of attention and fluctuating attention was undertaken in 155 patients with dementia (85 with DLB and 80 with AD) from a representative hospital dementia case register and 35 elderly controls using the Cognitive Drug Research Computerized Assessment System for Dementia Patients computerized neuropsychological battery. Operationalized clinical diagnosis was made using the consensus criteria for DLB and the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria for AD. High levels of sensitivity and specificity have been achieved for the first 50 cases undergoing postmortem examination. RESULTS: The groups were well matched for severity of cognitive impairments, but the AD patients were older (mean age, 80 vs 78 years) and more likely to be female (55% vs 40%). Patients with DLB were significantly more impaired than patients with AD on all measures of attention and fluctuating attention (for all comparisons, t > or = 2.5, P<.001), and patients from both dementia groups were significantly more impaired than elderly controls for all comparisons other than cognitive reaction time, which was significantly more impaired in DLB patients than controls but was comparable in controls and AD patients. There were, however, significant associations between the severity of cognitive impairment and the severity of both attentional deficits and fluctuations in attention. CONCLUSIONS: This large prospective study confirms that slowing of cognitive processing, attention, and fluctuations of attention are significantly more pronounced in DLB and AD patients, although fluctuating attention is common in patients with moderate-to-severe AD. Deficits of cognitive reaction time appear to be specific to DLB, except in severe dementia. A detailed evaluation of attentional performance could make an important contribution to differential diagnosis, although the results need to be interpreted within the context of the overall severity of cognitive deficits.     

Axis I phenomenology of borderline personality disorder

The Axis I phenomenology of 50 outpatients meeting both Diagnostic Interview for Borderlines (DIB) and DSM-III criteria for Borderline Personality Disorder (BPD), 29 outpatients meeting DSM-III criteria for Antisocial Personality Disorder (APD), and 26 outpatients meeting DSM-III criteria for Dsythymic Disorder as well as DSM-III criteria for some other type of Axis II disorder (dysthymic OPD) was assessed blind to clinical diagnosis using the Structured Clinical Interview for DSM-III (SCID). Borderlines were significantly more likely than antisocial controls to have met DSM-III criteria for an affective disorder, particularly Dysthymic Disorder, and an anxiety disorder. They were also significantly more likely than dysthymic OPD controls but significantly less likely than antisocial controls to have met DSM-III criteria for alcohol abuse/dependence and drug abuse/dependence. The authors conclude that: (1) the link between BPD and unipolar affective disorders is less specific than previously suggested, and (2) there is a link between BPD and impulse disorders that may be of equal, if not greater, importance.     

History of childhood abuse in panic disorder,social phobia,and generalized anxiety disorder

The authors examined the prevalence of self-reported childhood physical or sexual abuse in a sample of adult patients presenting for treatment of panic disorder, social phobia, or generalized anxiety disorder. Regardless of the presence of comorbid anxiety disorders or comorbid depression, patients with panic disorder had significantly higher rates of past childhood physical or sexual abuse than patients with social phobia. Patients with generalized anxiety disorder had intermediate rates of past physical or sexual abuse that were not significantly different from the other two diagnostic groups. Anxiety disorder patients with a history of childhood abuse were also more likely to have comorbid major depression than those without. These findings are discussed in terms of biological and behavioral factors that may influence the development of anxiety disorders after the experience of a traumatic event.     

Adverse outcomes associated with personality disorder not otherwise specified in a community sample

OBJECTIVE: The authors investigated 1) whether adolescents and adults in the community diagnosed with personality disorder not otherwise specified are at elevated risk for adverse outcomes, and 2) whether this elevation in risk is comparable with that associated with the DSM-IV cluster A, B, and C personality disorders. METHOD: A community-based sample of 693 mothers and their offspring were interviewed during the offspring's childhood, adolescence, and early adulthood. Offspring psychopathology, aggressive behavior, educational and interpersonal difficulties, and suicidal behavior were assessed. RESULTS: Individuals who met DSM-IV criteria for personality disorder not otherwise specified were significantly more likely than those without personality disorders to have concurrent axis I disorders and behavioral, educational, or interpersonal problems during adolescence and early adulthood. In addition, adolescents with personality disorder not otherwise specified were at significantly elevated risk for subsequent educational failure, numerous interpersonal difficulties, psychiatric disorders, and serious acts of physical aggression by early adulthood. Adolescents with personality disorder not otherwise specified were as likely to have these adverse outcomes as those with cluster A, B, or C personality disorders or those with axis I disorders. CONCLUSIONS: Adolescents and young adults in the general population diagnosed with personality disorder not otherwise specified may be as likely as those with DSM-IV cluster A, B, or C personality disorders to have axis I psychopathology and to have behavioral, educational, or interpersonal problems that are not attributable to co-occurring psychiatric disorders. Individuals with personality disorder not otherwise specified and individuals with DSM-IV cluster A, B, or C personality disorders are likely to be at substantially elevated risk for a wide range of adverse outcomes.     

The ethics of mandatory community treatment

The authors present three ethical arguments to address the controversy of mandatory community treatment: rights-based versus beneficence, utilitarian, and communitarian. Each approach suggests that mandatory community treatment can be an ethical intervention for individuals with severe mental disorders in well-defined circumstances. It is critical to recognize that such interventions cannot be effective in the absence of an adequately funded, quality mental health service system. Within such a system, the authors believe a program of mandatory community treatment may play an important role. In considering mandatory outpatient treatment, the authors argue that consideration of decisionmaking capacity is preferable to dangerousness criteria, that clinical criteria with some flexibility should be developed so that mandatory community treatment is used only when alternatives have failed, that mandatory community treatment should be implemented long enough to be effective, and that consumers must be involved in the development and implementation of mandatory outpatient treatment programs.     

Hallucinations and delusions in 1,715 patients with unipolar and bipolar affective disorders

The prevalence of hallucinations and delusions was studied in 1,715 patients with unipolar or bipolar affective disorders hospitalized at a tertiary care facility. The authors found that the presence of psychotic features was significantly associated with diagnostic subtype. Bipolar manics were more likely than primary depressives, secondary depressives, and bipolar depressives to have hallucinations and/or delusions; primary depressives were significantly more likely than secondary depressives to have psychotic features. Among psychotic patients, bipolar manics were more likely than the other diagnostic groups to have delusions only and less likely to have hallucinations only. Possible explanations for these findings are discussed.     

Utility of a Wisconsin card sorting test short form in persons with Alzheimer's and Parkinson's disease

Abstract

A diagnostic index, based on WAIS-R subtests, to identify patients with Dementia of the Alzheimer Type (DAT) and differentiate them from normal or depressed elderly was investigated. In a sample of 82 geriatric outpatient clinic patients who complained of memory loss, 22% of patients with probable DAT and 13% of nondemented patients obtained a positive profile. The occurrence of the profile in the two groups was not significantly different, nor were differences in education or severity of dementia found between subjects who did or did not obtain the profile. In a second sample of 173 elderly research volunteers, the profile occurred in 7% of DAT subjects, 10% of subjects complaining of memory loss who did not meet diagnostic criteria for DAT, 7% of nondemented major depressed subjects, and 7% of normal control subjects. Thus, the current investigation did not find the profile useful in differentiating DAT from other common disorders among elderly subjects. The authors conclude that a more comprehensive test battery remains the diagnostic tool of choice for differentiating DAT from other disorders.
