The autonomy of mood disorders among cocaine-using methadone patients.

This study uses an algorithm to determine whether patients dually diagnosed with a mood disorder and cocaine dependence have either (a) an autonomous mood disorder (onset of mood disorder prior to substance use disorder (SUD) or mood disorder symptoms persist during periods of abstinence or (b) a nonautonomous mood disorder (onset of SUD preceded mood disorder and mood disorder symptoms remit during periods of abstinence). The relationship among autonomy, patient characteristics, and treatment completion is examined. The sample included 67 methadone patients with a mood disorder (87% major depression, 13% bipolar) who were enrolling in a 6-month psychosocial treatment for cocaine use. Of these subjects, 27% were rated as having an autonomous mood disorder and 73% a nonautonomous mood disorder. Mean age was 37 years; 55% were female and 82% were Hispanic or African-American. All subjects had been stabilized on methadone (mean = 70 mg). During the 30 days prior to study intake, subjects with an autonomous mood disorder, compared to subjects with a nonautonomous mood disorder, reported fewer days using cocaine (12.5 versus 21.1) and fewer days drinking four or more drinks of alcohol (1.1 versus 6. 1). Treatment completion was associated with less cocaine use, autonomy, and African-American ethnicity. However, when these variables were controlled using logistic regression, only autonomous mood disorder and ethnicity predicted treatment completion. These results suggest that autonomy may be a useful construct to measure, and that subjects with nonautonomous mood disorders may need special efforts to ensure treatment retention.

Proton magnetic resonance spectroscopy of the frontal lobe and cerebellar vermis in children with a mood disorder and a familial risk for bipolar disorders.

OBJECTIVE: Few studies have examined the neurochemical abnormalities that might be associated with pediatric bipolar disorder. The aim of this study was to use magnetic resonance spectroscopy to evaluate several brain regions implicated in bipolar disorder in children with a mood disorder and a familial risk for bipolar disorder. We hypothesized that these children would exhibit neurochemical differences compared with healthy children of parents without a psychiatric disorder. Specifically, decreased N-acetylaspartate (NAA) and creatine and phosphocreatine (Cr) of the prefrontal cortex and cerebellar vermis would reflect impairments in neuronal function and cellular metabolism, and elevated myo-inositol (mI) would reflect impaired phosphoinositide metabolism, potentially representing early markers of neurophysiologic changes that might underlie the development of bipolar disorder. METHODS: Children with a mood disorder and at least one parent with bipolar disorder (n = 9) and healthy children (n = 10) group matched for age (8-12 years), race, sex, education, and Tanner stage were evaluated using the Washington University in St. Louis Kiddie Schedule for Affective Disorders and Schizophrenia. Proton magnetic resonance spectroscopy was acquired using 8-cc volumes within the frontal cortex, frontal white matter, and the cerebellar vermis. Metabolite ratios (NAA/Cr, cholines (Cho)/Cr, mI/Cr, NAA/Cho, NAA/mI, and Cho/mI) and concentrations (NAA, Cr, Cho, and mI) were calculated and compared between groups. RESULTS: The trend in concentration levels of NAA and Cr was approximately 8% lower for children with a mood disorder than healthy children within the cerebellar vermis. The frontal cortex in children with a mood disorder revealed elevated mI concentration levels, approximately 16% increased, compared with healthy children. CONCLUSIONS: Similar to findings in adults with bipolar disorders, neurochemical abnormalities within the frontal cortex and the cerebellar vermis were present in this preliminary comparison of children with a mood disorder and a familial risk for bipolar disorder. Larger sample sizes are needed to replicate these findings.

The accuracy of the Italian version of the Hypomania Checklist (HCL-32) for the screening of bipolar disorders and comparison with the Mood Disorder Questionnaire (MDQ) in a clinical sample.

BACKGROUND: The study measured the accuracy of the Italian version of the Hypomania Checklist (HCL-32) for self-assessment as a screening instrument for bipolar disorder (BPD) in a psychiatric setting and compared results with a previous study, carried out in a comparable sample and in the same setting, using the Mood Disorder Questionnaire (MDQ). METHODS: 123 consecutive subjects attending a psychiatric division were screened for BPD using the Italian translation of the HCL-32, and diagnostically interviewed with the SCID by physicians. The sample of the previous study using the MDQ consisted of 154 subjects. RESULTS: On the basis of the SCID: 26 received a diagnosis of bipolar/schizoaffective disorder, 57 were diagnosed as having at least another psychiatric disorder in Axis-I, whilst 40 were unaffected by any type of psychiatric disorder. Comparing the bipolar with all other patients the HCL-32 showed a good accuracy: cut-off 8: sensitivity 0.92-specificity 0.48; cut-off 10: sensitivity 0.88-specificity 0.54; cut-off 12: sensitivity 0.85-specificity 0.61. The accuracy for BPD-II (10) remains good: cut-off 8: sensitivity 0.90-specificity 0.42; cut-off 10: sensitivity 0.80-specificity 0.47; cut-off 12: sensitivity 0.80-specificity 0.54. The comparison with the MDQ performance shows that both screening tools may show good results, but HCL-32 seems to be more sensitive in detecting BPD-II. CONCLUSION: Our results seem to indicate good accuracy of HCL-32 as a screening instrument for BPD in a psychiatric setting, with a low rate of false negatives, and a fairly good degree of identification of BPD-II.

Juvenile mood disorders and office psychopharmacology.

Mood disorders afflict pediatric patients, cause significant impairment, and interfere with normal development. Increasingly, pediatricians are called on to assess and collaborate with mental health practitioners in medicating children and adolescents with mood disorders. Approaching the juvenile with a primary emphasis on clarifying the diagnoses, determining environmental antecedents and sequelae, and investigating suicide risk enables the pediatrician to institute appropriate treatment. Despite limited data from controlled studies, psychotherapy often is used for mild to moderate depression. Pharmacotherapy is indicated in cases unresponsive to psychotherapy and in severe or suicidal cases. First-line pharmacotherapy for depressed adolescents is usually an SRI followed by the atypical or TCA antidepressants. Bipolar disorder typically requires an aggressive medication regimen, including anticonvulsants, lithium, or a combination, as well as environmental modifications. With severe, difficult, or refractory cases, mental health consultation is recommended to clarify diagnoses and to provide psychotherapy and medication input.

Self-perceptions of interpersonal and sexual functioning in women with mood disorders: a preliminary report.

Women with mood disorders are faced with the complex interpersonal issues that confront all women, as well as the potential disruption in their interpersonal functioning related to the nature of their disorder and the medical treatment required. The purposes of this study were to describe the self-perceptions of 34 women being treated medically for mood disorders regarding (a) their interpersonal and sexual functioning, (b) the causal explanations for perceived disruptions in interpersonal and sexual functioning, and (c) the effect their mood disorder has had on their functioning in these areas. A structured questionnaire was used to conduct the in-depth interviews. Results indicated that 76.5% (n = 26) of the women perceived that they were experiencing interpersonal disruption, and 55.9% (n = 19) perceived that they were experiencing sexual disruption at the time of the interviews. Moreover, 88.2% (n = 30) reported that their mood disorder had an effect on their interpersonal relationships, and 79.4% (n = 27) reported that their mood disorder adversely affected their sexual relationships. Causal explanations related to the perceived disruptions in functioning were explored.

Diagnostic and measurement issues in the assessment of pediatric bipolar disorder: implications for understanding mood disorder across the life cycle.

The goal of this paper is to review assessment research of bipolar disorder in children and adolescents. The review addresses numerous themes: the benefits and costs of involving clinical judgment in the diagnostic process, particularly with regard to diagnosis and mood severity ratings; the validity of parent, teacher, and youth self-report of manic symptoms; how much cross-situational consistency is typically shown in mood and behavior; the extent to which a parent's mental health status influences their report of child behavior; how different measures compare in terms of detecting bipolar disorder, the challenges in comparing the performance of measures across research groups, and the leading candidates for research or clinical use; evidence-based strategies for interpreting measures as diagnostic aids; how test performance changes when a test is used in a new setting and what implications this has for research samples as well as clinical practice; the role of family history of mood disorder within an assessment framework; and the implications of assessment research for the understanding of phenomenology of bipolar disorder from a developmental framework.

Assessing unipolar mood disorders in women.

Among unipolar mood disorders, major depressive disorder (MDD) has traditionally been the most widely studied. There is, however, an alarming lack of extant research on the more mild mood disorders. Recent findings indicate that, collectively, milder unipolar mood disorders, such as dysthymic disorder (DD), and conditions specific to women, such as premenstrual dysphoric disorder (PMDD) and postpartum depression, functionally impair a large population of women. The course, mechanisms, and treatments of these illnesses are outlined, and specific areas of concern, including current available treatment applicability, gender differences in psychiatric testing, and the use of biological markers for the detection of illness, are detailed. Directions for future research are presented.

A taxometric investigation of the latent structure of social anxiety disorder in outpatients with anxiety and mood disorders.

The latent structure of social phobia was examined in a sample of 2,035 outpatients with anxiety and mood disorders to determine whether the disorder operates in a categorical or dimensional fashion. We performed three mathematically distinct taxometric procedures-MAMBAC, MAXEIG, and L-Mode-using five indicators constructed from clinical interview ratings and questionnaire measures of social anxiety symptoms. Results from screening analyses and simulated comparison data consistently indicated that the data were suitable for taxometric analysis. The collective results across procedures, consistency tests, and analysis of simulated comparison data produced converging evidence in support of the conclusion that the latent structure of social phobia is dimensional.

Ethical issues in research and innovative therapy in children with mood disorders.

Research involving children with mood disorders should generally offer a reasonable prospect of benefit to those involved, unless the risks are minimal. While federal regulations require a prospect of direct benefit, from an ethical perspective indirect benefits, such as the advantages of being in a clinical trial, are relevant. Standard care should not be presumed to be preferable to treatment in the context of a clinical trial, particularly if it has not been evaluated in well designed studies involving groups comparable to the patient. Similarly, active treatments in a controlled trial should not be presumed to be preferable to placebos, particularly in studies involving mood disorders where the placebo effect is more likely to be substantial. Innovative therapy-using approved drugs for unapproved purposes-may be more problematic than research, on theoretical and empirical grounds. Studies with no prospect of direct benefit and more than minimal risk are problematic when the patient is incompetent to provide meaningful consent. Whether or not a controlled trial involving children with mood disorders can be ethically justified depends on several factors, including the validity of standard treatment, the seriousness of the disorder, the likelihood of adverse consequences if treatment is delayed, the burden of the proposed intervention, and value judgments by parents, working collaboratively with a caring physician.

[Personality disorders prevalence study among inpatients with mood disorders, psychoactive use disorders and anxiety disorders].

OBJECTIVE: The aim of this study was to asses type and prevalence of Personality Disorders (PDs) and their patterns of comorbidity with Axis I disorders in a sample of psychiatric inpatients. SETTING: The sample consisted of 300 subjects admitted to a psychiatric unit on a voluntary bases for an index episode. The study was conducted over a period of 12 months, from 1.11.1997 to 31.10.1998. MAIN OUTCOME MEASURES: The Italian version of SCID-II-PQ (Structured Clinical Interview for DSM-III-R personality disorders, with Personality Questionnaire--PQ--a self report questionnaire). RESULTS: More than half the patients had at least one personality disorder. The mean of disorders per patient was 2.83 +/- 1.93 (+/- SD). The most prevalent Axis II disorders were Borderline PD (30.7%), Obsessive-compulsive PD (30.7%) and Avoidant PD (25.3%). Women were significantly more likely than men to meet criteria for Dependent PD and Avoidant PD. Man showed significantly more frequently than women Antisocial PD. Significant associations (p < 0.05) were found for comorbidity of Mood Disorders and Avoidant PD, and for Psicoactive Use Disorders and Antisocial PD. CONCLUSIONS: Our study confirms the high prevalence of PDs in psychiatric inpatients and showe some interesting associations between Axis I and Axis II disorders. These results can't be generalized to outpatients because our clinical sample involved mainly severely ill inpatients, but they raise questions about the exact nature of PDs and of the relationship with Axis I disorders. Further research involving outpatients and general population is needed to examine factors that could affect development and course of Personality Disorders.

[Intellectual and mood disorders in multiple sclerosis].

Reports of frequency and interpretation of intellectual and mood disorders differ in multiple sclerosis (MS). Forty-one patients with MS defined according to MacAlpine's criteria were evaluated by psychometric tests (WAIS) and neuropsychologic examinations (study of language, gnosic and praxic activities, dynamic gestural organization, memory and learning) together with, in 24 of them, the AMDP psychopathologic rating scale. Intellectual disorders were noted in 65 p. 100 of patients. Although more frequent in severe and chronic forms they were nevertheless of early onset since more than a half of the patients with onset of disease less than 5 years ago were affected. Their semiology was fairly homogeneous, combining disturbances of dynamic gestural organization (decomposition or simplification) and memory and learning deficiencies without anomalies of instrumental functions or usual psychometric mental deterioration. Application of the AMDP scale failed to reveal any psychotic type of disorders. Mood disturbances were predominant, affecting 60 p. 100 of the subpopulation studied (24 cases) and combining, in an unexpected manner: dysphoria, euphoria and depression. Only euphoria appeared to be correlated with intellectual disorders. Frequency of both intellectual and mood disorders was similar to that reported in other series published. The relative homogeneity of semiology, seen by the correlation between the different disturbances (decomposition and simplification, plateau learning curve and euphoria) and the unusual grouping of these effects, is suggestive of their organic basis. In addition, signs and symptoms resemble the neuropsychological expression of frontal lobe lesions and certain lesions of central grey nuclei.(ABSTRACT TRUNCATED AT 250 WORDS)

Neuroreceptor imaging of stress and mood disorders.

Techniques such as positron emission tomography and single photon emission computed tomography allow for the imaging of neurotransmitter receptors and transporters in the brain. These tools have been used to investigate serotonergic, dopaminergic, and opioidergic function in healthy subjects as well as in patients with major depressive disorder, bipolar disorder, and other mood disorders. Pharmacologic challenges, such as amphetamine challenge, and physiologic stressors, such as pain challenge, have been used to further examine the function of these neurotransmitter systems. Neuroimaging of patient populations before and after medication treatment may be useful to understand changes in neurotransmission that accompany disease remission. As new radiotracers with higher selectivity for the various receptors and transporters are developed, imaging techniques may provide new insights into the pathophysiology of mood disorders, leading to improved diagnosis and treatment.

Validity of the mood disorder questionnaire: a general population study.

OBJECTIVE: This study tested the validity in the adult general population of the Mood Disorder Questionnaire, a screening instrument for bipolar I and II disorders. The Mood Disorder Questionnaire has been validated in a psychiatric outpatient study group. METHOD: A total of 711 subjects (stratified by Mood Disorder Questionnaire score) were randomly selected from a group of 85,358 adult respondents in a nationwide epidemiological general population sample that was balanced for key demographic variables. Of these, 695 subjects received a telephone interview involving an abbreviated version of the Structured Clinical Interview for DSM-IV. RESULTS: A sensitivity of 0.281 and a specificity of 0.972 were obtained for the Mood Disorder Questionnaire. CONCLUSIONS: The Mood Disorder Questionnaire is a useful screening instrument for bipolar I and II disorders in the community. The operating characteristics of the Mood Disorder Questionnaire in the general population differ substantially from its characteristics in outpatient psychiatric settings.

Temporal sequencing of lifetime mood disorders in relation to comorbid anxiety and substance use disorders--findings from the Netherlands Mental Health Survey and Incidence Study.

BACKGROUND: Little is known about the temporal sequencing of psychiatric disorders. The aim of this study was to obtain insight into patterns of co-occurrence of DSM-III-R mood disorders in relation to anxiety and substance use disorders, their temporal sequencing and the sociodemographic and long-term vulnerability predictors of this temporal sequencing. METHODS: Data are from the Netherlands Mental Health Survey and Incidence Study (NEMESIS), a psychiatric epidemiological study in a representative sample of 7,076 adults aged 18-64. RESULTS: Of those who had ever experienced a mood disorder, 46 % of males and 57 % of females had a history of anxiety disorders, and 43 % and 15 % of substance use disorders. Mood disorders were associated with all anxiety and substance use disorders, except with alcohol abuse among males. In the majority of anxiety-comorbid cases, the mood disorder arose after the anxiety disorder; the pattern for substance use-comorbid disorders was more variable. Deviation from the usual sequence of major depression and anxiety disorders was more often seen among females, subjects with a higher educational level, subjects who experienced childhood parental divorce, and subjects who experienced childhood emotional neglect. CONCLUSIONS: When comorbid with anxiety disorders, mood disorders clearly tend to be secondary. Few of the studied demographic factors, familial vulnerability factors and childhood life events predict the sequencing of mood disorders in relation to other disorders.

CSF thyrotropin-releasing hormone concentrations differ in patients with schizoaffective disorder from patients with schizophrenia or mood disorders.

OBJECTIVE: To determine if there were differences in CSF-TRH concentrations among several acute major psychiatric disorders and to investigate the effects of antipsychotic treatment on CSF-TRH levels. METHOD: CSF-TRH concentrations were measured in 62 psychiatric inpatients during an acute phase of illness after a drug-free period. CSF-TRH measurements were repeated in 14 of these patients after 4 weeks of antipsychotic treatment. RESULTS: Post-hoc tests (Tukey HSD) revealed significant differences among patients with schizoaffective disorder and both schizophrenia (P<0.03) and major depression (P<0.01). There were no significant differences between pre and posttreatment levels of CSF-TRH in the 14 patients treated with conventional agents for 4 weeks (1.54 pg/ml vs. 1.47 pg/ml). However, patients with a reduction in CSF-TRH concentration had a significantly better symptom response measured by the Brief Psychiatric Rating Scale (BPRS) positive factor (61% in six subjects) vs. those who had an increase in posttreatment CSF-TRH (29% in eight subjects; t=2.2; d.f.=12; P<0.04). CONCLUSIONS: These results provide further evidence for a neuromodulatory role for TRH and suggest a re-examination of its behavioral effects and interactions with brain neurotransmitter systems relevant to major psychotic and mood disorders.

Pediatric bipolar mood disorder.

The diagnosis of bipolar mood disorder (BP) in preadolescents (pediatric mania) has generated considerable controversy in terms of its estimated prevalence and validity as a diagnostic category. The relative paucity of systematic studies and the current diagnostic confusion related to the disorder are often attributed to the apparent discontinuities in the childhood versus adult presentation of the illness, namely, irritability as the predominant "mood" of mania and a continuous course of symptoms. The goal of this article is to review the current literature and identify sources of confusion relating to pediatric mania by considering results to date within a larger context that include findings from studies on (1) BP illness in adults, (2) mood disorders across the lifespan, (3) the role of development in symptom expression, and (4) patterns of heritability in psychiatric disorders. Whereas much remains to be investigated in the validation of the diagnosis for children, integrating results across studies may provide a framework for understanding the differences in the presentation of severe mood disorders in children and adults.

Development and natural history of mood disorders.

To expand and accelerate research on mood disorders, the National Institute of Mental Health (NIMH) developed a project to formulate a strategic research plan for mood disorder research. One of the areas selected for review concerns the development and natural history of these disorders. The NIMH convened a multidisciplinary Workgroup of scientists to review the field and the NIMH portfolio and to generate specific recommendations. To encourage a balanced and creative set of proposals, experts were included within and outside this area of research, as well as public stakeholders. The Workgroup identified the need for expanded knowledge of mood disorders in children and adolescents, noting important gaps in understanding the onset, course, and recurrence of early-onset unipolar and bipolar disorder. Recommendations included the need for a multidisciplinary research initiative on the pathogenesis of unipolar depression encompassing genetic and environmental risk and protective factors. Specifically, we encourage the NIMH to convene a panel of experts and advocates to review the findings concerning children at high risk for unipolar depression. Joint analyses of existing data sets should examine specific risk factors to refine models of pathogenesis in preparation for the next era of multidisciplinary research. Other priority areas include the need to assess the long-term impact of successful treatment of juvenile depression and known precursors of depression, in particular, childhood anxiety disorders. Expanded knowledge of pediatric-onset bipolar disorder was identified as a particularly pressing issue because of the severity of the disorder, the controversies surrounding its diagnosis and treatment, and the possibility that widespread use of psychotropic medications in vulnerable children may precipitate the condition. The Workgroup recommends that the NIMH establish a collaborative multisite multidisciplinary Network of Research Programs on Pediatric-Onset Bipolar Disorder to achieve a better understanding of its causes, course, treatment, and prevention. The NIMH should develop a capacity-building plan to ensure the availability of trained investigators in the child and adolescent field. Mood disorders are among the most prevalent, recurrent, and disabling of all illnesses. They are often disorders of early onset. Although the NIMH has made important strides in mood disorders research, more data, beginning with at-risk infants, children, and adolescents, are needed concerning the etiology and developmental course of these disorders. A diverse program of multidisciplinary research is recommended to reduce the burden on children and families affected with these conditions.

Risk factors associated with the development of postpartum mood disorders.

BACKGROUND: Various factors have been reported to be associated with the development of postpartum mood disorders. The relationship between postpartum mood disorders and putatively hormone-related phenomena such as premenstrual dysphoric disorder (PMDD) is unclear. This study attempts to determine whether such mood phenomena are risk factors for postpartum mood disorders. METHODS: Postpartum women (n=1800) were assessed for risk factors for postpartum mood disorders during the first 2-4 days after parturition. Of these, 133 were defined as "high risk" and 109 as "low risk" according to fixed criteria. A structured phone diagnostic interview was performed at 6-8 weeks postpartum to assess for the presence of postpartum depression or the blues. RESULTS: Premenstrual dysphoric disorder (PMDD), mood symptoms during the first 2-4 days postpartum, a past history of depression and mood symptoms during past oral contraceptive use, were found to be significant risk factors for postpartum mood disorders. Women at high risk for postpartum mood disorders had a 9.3-, 1.5-, 1.6- and 2.6-fold increase in risk for major depression, minor depression, the blues and adjustment disorder respectively compared to women at low risk. LIMITATIONS: While the study design is prospective, it is limited by the retrospective assessment of risk factors. CONCLUSIONS: This study provides preliminary evidence that putatively hormone-related phenomena such as PMDD are related to the occurrence of postpartum mood disorders. The results go some way to support the hypothesis that the etiology for postpartum mood disorders may be related to differential hormonal sensitivity. Such risk factors should be included in any assessment of the risk for these disorders.
