Underdiagnosis of bipolar disorder in men with substance use disorder.

OBJECTIVE: Recent reports indicate that bipolar disorder is frequently underdiagnosed in the clinical population, leading to overuse of antidepressants and underuse of mood stabilizers. This study assessed rates of diagnosis of bipolar disorder in a substance abuse population. METHOD: The study involved a retrospective chart review of data from 295 patients admitted to an inpatient substance abuse program for men. Data were then analyzed from the 85 patients in the sample who were diagnosed as meeting DSM-IV criteria for bipolar disorder on intake into the program. Charts were reviewed for relevant clinical and demographic data. The primary outcome measure was the rate of previous misdiagnosis. RESULTS: Of the 85 patients diagnosed with bipolar disorder upon intake, 42 (49%) had not been previously diagnosed with bipolar disorder; of these 42, 6 (14%) patients had not been assessed previously, while 36 (86%) had been assessed previously and had received many other psychiatric diagnoses, including major depression (77%), attention-deficit/hyperactivity disorder (20%), and panic disorder (3%). Among the comorbid substance use disorders in these patients, alcohol dependence was the most common (62%), followed by cocaine (38%), opioid (26%), polysubstance (12%), and sedative-hypnotic (2%) dependence. Other comorbid Axis I disorders included posttraumatic stress disorder (14%), attention-deficit/hyperactivity disorder (10%), panic disorder (2%), and generalized anxiety disorder (2%). CONCLUSION: This study found that bipolar disorder had not been previously diagnosed in approximately 50% of a sample of Caucasian males in a substance abuse population who were diagnosed with bipolar disorder upon admission to an inpatient substance abuse program.

Prevalence of mental disorders in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project.

OBJECTIVE: To describe the 12-month and lifetime prevalence rates of mood, anxiety and alcohol disorders in six European countries. METHOD: A representative random sample of non-institutionalized inhabitants from Belgium, France, Germany, Italy, the Netherlands and Spain aged 18 or older (n = 21425) were interviewed between January 2001 and August 2003. DSM-IV disorders were assessed by lay interviewers using a revised version of the Composite International Diagnostic Interview (WMH-CIDI). RESULTS: Fourteen per cent reported a lifetime history of any mood disorder, 13.6% any anxiety disorder and 5.2% a lifetime history of any alcohol disorder. More than 6% reported any anxiety disorder, 4.2% any mood disorder, and 1.0% any alcohol disorder in the last year. Major depression and specific phobia were the most common single mental disorders. Women were twice as likely to suffer 12-month mood and anxiety disorders as men, while men were more likely to suffer alcohol abuse disorders. CONCLUSION: ESEMeD is the first study to highlight the magnitude of mental disorders in the six European countries studied. Mental disorders were frequent, more common in female, unemployed, disabled persons, or persons who were never married or previously married. Younger persons were also more likely to have mental disorders, indicating an early age of onset for mood, anxiety and alcohol disorders.

Quality of life and psychiatric morbidity in panic disorder and generalized anxiety disorder.

OBJECTIVE: This report examines the impact of panic disorder and/or generalized anxiety disorder on quality of life and the implications of these findings on nosological categories. METHOD: A total of 357 subjects with a current episode of panic disorder and/or generalized anxiety disorder were diagnosed according to DSM-III-R criteria, using structured clinical interviews, as part of a prospective, naturalistic, longitudinal, multicenter study of a clinical population with anxiety disorders. RESULTS: There was a high degree of coexistence of anxiety disorders and major depressive disorder. Subjects with generalized anxiety disorder almost universally had other disorders, were the most likely to have at least one other anxiety disorder or major depressive disorder at intake, had the earliest age at onset, and had the worst emotional health rating. Subjects with panic disorder without agoraphobia had the most likelihood of a history of alcohol abuse. Nine percent of the subjects had a history of suicide attempts or gestures. CONCLUSIONS: The subjects showed significant impairment in quality of life. The highly frequent coexistence of other anxiety disorders with generalized anxiety disorder and the overall lack of differences on many quality of life measures raise questions of nosology, particularly for generalized anxiety disorder.

Influence of psychiatric comorbidity on recovery and recurrence in generalized anxiety disorder, social phobia, and panic disorder: a 12-year prospective study.

OBJECTIVE: The authors sought to observe the long-term clinical course of anxiety disorders over 12 years and to examine the influence of comorbid psychiatric disorders on recovery from or recurrence of panic disorder, generalized anxiety disorder, and social phobia. METHOD: Data were drawn from the Harvard/Brown Anxiety Disorders Research Program, a prospective, naturalistic, longitudinal, multicenter study of adults with a current or past history of anxiety disorders. Probabilities of recovery and recurrence were calculated by using standard survival analysis methods. Proportional hazards regression analyses with time-varying covariates were conducted to determine risk ratios for possible comorbid psychiatric predictors of recovery and recurrence. RESULTS: Survival analyses revealed an overall chronic course for the majority of the anxiety disorders. Social phobia had the smallest probability of recovery after 12 years of follow-up. Moreover, patients who had prospectively observed recovery from their intake anxiety disorder had a high probability of recurrence over the follow-up period. The overall clinical course was worsened by several comorbid psychiatric conditions, including major depression and alcohol and other substance use disorders, and by comorbidity of generalized anxiety disorder and panic disorder with agoraphobia. CONCLUSIONS: These data depict the anxiety disorders as insidious, with a chronic clinical course, low rates of recovery, and relatively high probabilities of recurrence. The presence of particular comorbid psychiatric disorders significantly lowered the likelihood of recovery from anxiety disorders and increased the likelihood of their recurrence. The findings add to the understanding of the nosology and treatment of these disorders.

Panic disorder with familial bipolar disorder.

If bipolar disorder is genetically heterogeneous, it may be possible to discern clinically heterogeneous familial subtypes based on differential risk for psychiatric comorbidity, for example panic disorder. We evaluated 528 members of 57 families ascertained for a genetic linkage study of bipolar disorder. Families were assorted according to the panic disorder diagnosis of the bipolar proband; the rates of panic and other disorders in relatives were compared. Eighty-eight percent of the 41 subjects with panic disorder had bipolar disorder. Panic disorder was diagnosed in 18% of family members with bipolar disorder. Ten of 57 bipolar probands had panic disorder. Their bipolar first-degree relatives had a significantly higher prevalence of panic disorder, bipolar II, cyclothymia, and dysthymia, but had lower prevalence of substance abuse than the relatives of the bipolar probands without panic disorder. These findings suggest the testable hypothesis that comorbid panic disorder is a marker of genetic heterogeneity in bipolar disorder.

The prevalence of comorbid anxiety in schizophrenia, schizoaffective disorder and bipolar disorder.

OBJECTIVE: The aim of this study to determine the prevalence of anxiety disorders in publically treated psychiatric inpatients with a DSM-IV diagnosis of schizophrenia, schizoaffective disorder or bipolar disorder. METHOD: Using the Structured Clinical Interview for DSM-III-R (SCID), 100 consecutive inpatients with a psychotic disorder were examined for the presence or absence of an anxiety disorder. Questionnaire measures of phobias, obsessive-compulsive and general anxiety symptoms were also applied. RESULTS: The prevalences of social phobia (17%), obsessive-compulsive disorder (13%) and generalised anxiety disorder in schizophrenia were relatively high, as were prevalences of obsessive-compulsive (30%) and panic disorder (15%) in bipolar disorder. The proportion of subjects with an anxiety disorder (43-45%) was almost identical across the three psychoses, with some evidence of gender differences. Although self-ratings of overall psychiatric symptoms were significantly elevated in those with anxiety disorders, hospital admission rates were not. CONCLUSIONS: Almost none of those with anxiety disorders were being treated for them, primarily because the severity of the acute psychotic illness required full diagnostic and therapeutic attention. Patients were generally discharged as soon as their psychotic episode was resolved, with little recognition of the presence of an anxiety disorder. Given that anxiety disorders are relatively responsive to treatment, greater awareness of their comorbidity with psychosis should yield worthwhile clinical benefits.

Prevalence of attention-deficit/hyperactivity disorder and conduct disorder among substance abusers.

BACKGROUND: This cross-sectional study sought to determine the prevalence of attention-deficit/hyperactivity disorder (ADHD) and conduct disorder among adults admitted to 2 chemical dependency treatment centers. It was hypothesized that ADHD alone or in combination with conduct disorder would be overrepresented in a population of patients with psychoactive substance use disorders. METHOD: Two hundred one participants were selected randomly from 2 chemical dependency treatment centers. Standardized clinical interviews were conducted using the Structured Clinical Interview for DSM-IV, the Addiction Severity Index, and DSM-IV criteria for ADHD. Reliabilities for the diagnostic categories were established using the Cohen kappa, and the subgroups of individuals with and without ADHD and conduct disorder were compared. RESULTS: Forty-eight (24%) of the participants were found to meet DSM-IV criteria for ADHD. The prevalence of ADHD was 28% in men (30/106) and 19% in women (18/95; NS). Seventy-nine participants (39%) met criteria for conduct disorder, and 34 of these individuals also had ADHD. Overall, individuals with ADHD (compared with those without ADHD) were more likely to have had more motor vehicle accidents. Women with ADHD (in comparison with women without ADHD) had a higher number of treatments for alcohol abuse. Individuals with conduct disorder (in comparison with those without conduct disorder) were younger, had a greater number of jobs as adults, and were more likely to repeat a grade in school, have a learning disability, be suspended or expelled from school, have an earlier age at onset of alcohol dependence, and have had a greater number of treatments for drug abuse. They were more likely to have a lifetime history of abuse of and/or dependence on cocaine, stimulants, hallucinogens, and/or cannabis. CONCLUSION: A significant overrepresentation of ADHD exists among inpatients with psychoactive substance use disorders. Over two thirds of those with ADHD in this sample also met criteria for conduct disorder. Our sample had a very large overlap between ADHD and conduct disorder, and the major comorbidities identified here were attributable largely to the presence of conduct disorder. Individuals who manifest conduct disorder and/or ADHD represent a significant proportion of those seeking treatment for psychoactive substance use disorders. They appear to have greater comorbidity and may benefit from a treatment approach that addresses these comorbidities specifically through medical and behavioral therapies.

Lifetime comorbidity of DSM-IV mood and anxiety disorders and specific drug use disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

OBJECTIVE: To present nationally representative data on the lifetime prevalence and comorbidity of 8 specific drug use disorders, separately for abuse and dependence, and mood and anxiety disorders. METHOD: Data come from a representative sample (N=43,093) of the United States civilian, noninstitutional population 18 years and older. Diagnoses of mood, anxiety, and drug use disorders were based upon face-to-face personal interviews using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV Version (AUDADIS-IV). RESULTS: Associations between specific mood and anxiety disorders and specific drug use disorders were virtually all positive and statistically significant (p<.05). In general, associations were greater for dependence than abuse, greater for mood than anxiety disorders, and in some instances stronger among women than men (p<.05). Large odds ratios also were observed for individuals with comorbid mood and anxiety disorders. CONCLUSION: The comorbidity between specific mood and anxiety disorders and specific drug use disorders is pervasive in the U.S. population. Findings suggest that comorbid psychiatric disorders may increase the risk of greater involvement in more serious illicit drug use disorders and that the greater comorbidity between mood and anxiety and drug use disorders among women may reflect greater deviance and psychopathology among drug-using women than men. Findings also suggest that drug abuse prevention and intervention efforts should address other psychiatric conditions. Further, definitions of drug use disorder phenotypes should give careful consideration to other psychiatric conditions as meaningful characteristics of case heterogeneity.

Co-occurrence of 12-month alcohol and drug use disorders and personality disorders in the United States: results from the National Epidemiologic Survey on Alcohol and Related Conditions.

BACKGROUND: Very little information is available on the co-occurrence of different personality disorders (PDs) and alcohol and drug use disorders in the US population. OBJECTIVE: To present national data on sex differences in the co-occurrence of Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol and drug use disorders and 7 of the 10 DSM-IV PDs. DESIGN: Face-to-face interviews conducted in the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (N = 43 093). SETTING: The United States and the District of Columbia, including Alaska and Hawaii. PARTICIPANTS: Household and group-quarters residents, aged 18 years and older. RESULTS: Among individuals with a current alcohol use disorder, 28.6% (95% confidence interval [CI], 26.7-30.6) had at least 1 PD, whereas 47.7% (95% CI, 43.9-51.6) of those with a current drug use disorder had at least 1 PD. Further, 16.4% (95% CI, 15.1-17.6) of individuals with at least 1 PD had a current alcohol use disorder and 6.5% (95% CI, 5.7-7.3) had a current drug use disorder. Associations between PDs and alcohol and drug use disorders were overwhelmingly positive and significant (P <.05). Overall, alcohol use disorders were most strongly related to antisocial (odds ratio [OR], 4.8; 95% CI, 4.1-5.6), histrionic (OR, 4.7; 95% CI, 3.8-5.8), and dependent (OR, 3.0; 95% CI, 1.9-4.8) PDs. Drug use disorders also were more highly associated with antisocial (OR, 11.8; 95% CI, 9.7-14.3), histrionic (OR, 8.0; 95% CI, 6.0-10.7), and dependent (OR, 11.6; 95% CI, 7.1-19.1) PDs. Associations between obsessive-compulsive, histrionic, schizoid, and antisocial PDs and specific alcohol and drug use disorders were significantly stronger (P <.04) among women than men, whereas the association between dependent PD and drug dependence was significantly greater (P <.04) among men than women. CONCLUSIONS: The co-occurrence of PDs with alcohol and drug use disorders is pervasive in the US population. Results highlight the need for further research on the underlying structure of these disorders and the treatment implications of these disorders when comorbid.

DSM-III-R schizotypal personality traits in offspring of schizophrenic disorder, affective disorder, and normal control parents.

The aggregation of disorder in families identified by a schizophrenic disorder proband (index case) has provided indirect clues to the question of diagnostic boundaries of schizophrenic spectrum categories. The Danish Adoption Studies provided quasi-experimental evidence for the range of expression of a putative schizophrenic spectrum disorder which was subsequently denoted schizotypal personality disorder (STPD) in DSM-III-R. It has been hypothesized that such schizophrenic spectrum categories bear a genetic relationship to schizophrenic disorder and thus are continuous with schizophrenia in terms of etiology and pathogenesis. For meaningful use of such spectrum categories in genetic analyses, i.e., linkage analysis, it is important that rates of spectrum traits and disorder in normal control and in psychiatric control populations are known. The rate of DSM-III-R schizotypal traits and disorder was assessed in three offspring groups (ages 18-29) defined by parental diagnoses, including schizophrenic disorder (N = 90), affective disorder (N = 79), and no parental disorder (N = 161). The assessment was conducted by trained social workers and psychologists by means of a direct interview (Personality Disorder Examination). The interviewers were blind to the parental status and to previous psychiatric assessments of these offspring. The rates of three, four and five schizotypal features were elevated in the offspring with parental psychiatric disorder in contrast to the offspring with no parental psychiatric disorder. However, the rates between the offspring of the schizophrenic disorder parental group and the offspring of the affective disorder parental group did not differ significantly, thus failing to support the assumption of diagnostic specificity.

The familial phenotype of obsessive-compulsive disorder in relation to tic disorders: the Hopkins OCD family study.

BACKGROUND: Obsessive-compulsive disorder (OCD) and tic disorders have phenomenological and familial-genetic overlaps. An OCD family study sample that excludes Tourette's syndrome in probands is used to examine whether tic disorders are part of the familial phenotype of OCD. METHODS: Eighty case and 73 control probands and their first-degree relatives were examined by experienced clinicians using the Schedule for Affective Disorders and Schizophrenia-Lifetime Anxiety version. DSM-IV psychiatric diagnoses were ascertained by a best-estimate consensus procedure. The prevalence and severity of tic disorders, age-at-onset of OCD symptoms, and transmission of OCD and tic disorders by characteristics and type of proband (OCD + tic disorder, OCD - tic disorder) were examined in relatives. RESULTS: Case probands and case relatives had a greater lifetime prevalence of tic disorders compared to control subjects. Tic disorders spanning a wide severity range were seen in case relatives; only mild severity was seen in control relatives. Younger age-at-onset of OCD symptoms and possibly male gender in case probands were associated with increased tic disorders in relatives. Although relatives of OCD + tic disorder and OCD - tic disorder probands had similar prevalences of tic disorders, this result is not conclusive. CONCLUSIONS: Tic disorders constitute an alternate expression of the familial OCD phenotype.

The impact of comorbid anxiety disorders on the course of dysthymic disorder: a 5-year prospective longitudinal study.

BACKGROUND: Few studies have examined the impact of comorbid anxiety disorder on the course of dysthymic disorder despite the high rate of comorbidity between these disorders. This research prospectively examines the naturalistic course of dysthymic disorder in patients with and without a comorbid anxiety disorder over a 5-year period. METHODS: Thirty-two comorbid patients and 54 non-comorbid patients with dysthymic disorder were assessed at three different time points (baseline, 30 months, and 60 months). Follow-up assessments included the Longitudinal Interval Follow-Up Evaluation and Hamilton Rating Scale for Depression (HRSD). RESULTS: The rate of recovery from dysthymic disorder was significantly lower in patients with (31.3%) than without (61.1%) comorbid anxiety disorders and, at all three time points, patients with comorbid anxiety had significantly higher HRSD scores. The estimated recovery rate from anxiety disorders was 53.8%. Only five of the comorbid patients recovered from both dysthymic disorder and all anxiety disorders during follow-up. Including new onsets, 72.1% of patients experienced an episode of an anxiety disorder during the 5 years. LIMITATIONS: There was no pure anxiety disorder group and patients were asked to report on relatively lengthy follow-up intervals. CONCLUSIONS: While the course of dysthymic disorder is debilitating, these results suggest that the prognosis for patients with a comorbid anxiety disorder is even poorer.

The functioning and well-being of patients with unrecognized anxiety disorders and major depressive disorder.

This study examines the degree to which untreated anxiety disorders and major depressive disorder, occurring either singly or in combination, reduce functioning and well-being among primary care patients. Adult patients were screened using the SCL-52 to identify those with clinically significant anxiety symptoms. They also completed the Rand Short-Form (SF-36) to measure self-reported patient functioning and well-being. Patients with untreated disorders were identified using the Q-DIS-III-R to diagnose six DIS-anxiety disorders (generalized anxiety disorder, post-traumatic stress disorder (PTSD), simple phobia, social phobia, panic/agoraphobia, obsessive/compulsive disorder) and major depression. Of 319 patients identified, 137 (43%) had a single disorder and 182 (57%) had multiple disorders. Regression models estimated the relative effects of these disorders on health status (SF-36) by comparing patients with the disorders to patients screened as being not-anxious. Estimates of these effects were consistent with available national norms. The estimated effect of each single disorder on all subscales for physical, social and emotional functioning was negative, often as much as a 20-30 point reduction on this 100-point scale. Major depression had the greatest negative impact, followed by PTSD and panic/ agoraphobia. For patients with multiple disorders, the presence of major depression was associated with the greatest reduction in functioning status. The impact of untreated anxiety disorders and major depressive disorder on functioning was comparable to, or greater than, the effects of medical conditions such as low back pain, arthritis, diabetes and heart disease.

Family study of the aggregation of eating disorders and mood disorders.

BACKGROUND: Family studies have suggested that eating disorders and mood disorders may coaggregate in families. To study further this question, data from a family interview study of probands with and without major depressive disorder was examined. METHOD: A bivariate proband predictive logistic regression model was applied to data from a family interview study, conducted in Innsbruck, Austria, of probands with (N = 64) and without (N = 58) major depressive disorder, together with 330 of their first-degree relatives. RESULTS: The estimated odds ratio (OR) for the familial aggregation of eating disorders (anorexia nervosa, bulimia nervosa and binge-eating disorder) was 7.0 (95 % CI 1.4, 28; P = 0.006); the OR for the familial aggregation of mood disorders (major depression and bipolar disorder) was 2.2 (0.92, 5.4; P = 0.076); and for the familial coaggregation of eating disorders with mood disorders the OR was 2.2 (1.1, 4.6; P = 0.035). CONCLUSIONS: The familial coaggregation of eating disorders with mood disorders was significant and of the same magnitude as the aggregation of mood disorders alone--suggesting that eating disorders and mood disorders have common familial causal factors.

Symptoms of eating disorders in patients with obsessive-compulsive disorder.

OBJECTIVE: This study was designed to explore potential overlap of the symptoms of obsessive-compulsive disorder and eating disorders. METHOD: The authors administered a structured, self-rating scale, the Eating Disorder Inventory, to 59 outpatients at an obsessive-compulsive disorder clinic and to 60 sex-matched normal volunteers. The Eating Disorder Inventory has been previously validated as a reliable measure of the specific cognitive and behavioral dimensions of the psychopathology typical of patients with eating disorders. The scores of the patients with obsessive-compulsive disorder and of the healthy comparison subjects were compared with those of 32 female inpatients with anorexia nervosa (N = 10) or bulimia nervosa (N = 22) who had also been given the inventory. RESULTS: The patients with obsessive-compulsive disorder scored significantly higher than the healthy comparison subjects on all eight subscales of the Eating Disorder Inventory: drive for thinness, bulimia, body dissatisfaction, ineffectiveness, perfectionism, interpersonal distrust, interoceptive awareness, and maturity fears. Relative to the healthy subjects, male patients with obsessive-compulsive disorder had more symptoms than female patients with obsessive-compulsive disorder. The scores of the female patients with obsessive-compulsive disorder were midway between those of the 32 female patients with eating disorders and those of the 35 female normal subjects. CONCLUSIONS: These results suggest that patients with obsessive-compulsive disorder display significantly more disturbed eating attitudes and behavior than healthy comparison subjects and that they share some of the psychopathological eating attitudes and behavior that are common to patients with eating disorders.

Family history of suicidal behavior and mood disorders in probands with mood disorders.

OBJECTIVE: First-degree relatives of persons with mood disorder who attempt suicide are at greater risk for mood disorders and attempted or completed suicide. This study examined the shared and distinctive factors associated with familial mood disorders and familial suicidal behavior. METHOD: First-degree relatives' history of DSM-IV-defined mood disorder and suicidal behavior was recorded for 457 mood disorder probands, of whom 81% were inpatients and 62% were female. Probands' lifetime severity of aggression and impulsivity were rated, and probands' reports of childhood physical or sexual abuse, suicide attempts, and age at onset of mood disorder were recorded. Univariate and multivariate analyses were carried out to identify predictors of suicidal acts in first-degree relatives. RESULTS: A total of 23.2% of the probands with mood disorder who had attempted suicide had a first-degree relative with a history of suicidal behavior, compared with 13.2% of the probands with mood disorder who had not attempted suicide (odds ratio=1.99, 95% CI=1.21-3.26). Thirty percent (30.8%) of the first-degree relatives with a diagnosis of mood disorder also manifested suicidal behavior, compared with 6.6% of the first-degree relatives with no mood disorder diagnosis (odds ratio=6.25, 95% CI=3.44-11.35). Probands with and without a history of suicide attempts did not differ in the incidence of mood disorder in first-degree relatives (50.6% versus 48.1%). Rates of reported childhood abuse and severity of lifetime aggression were higher in probands with a family history of suicidal behavior. Earlier age at onset of mood disorder in probands was associated with greater lifetime severity of aggression and higher rates of reported childhood abuse, mood disorder in first-degree relatives, and suicidal behavior in first-degree relatives. CONCLUSIONS: Risk for suicidal behavior in families of probands with mood disorders appears related to early onset of mood disorders, aggressive/impulsive traits, and reported childhood abuse in probands. Studies of such clinical features in at-risk relatives are under way to determine the relative transmission of these clinical features.

Sustained attention and visual processing speed in children and adolescents with bipolar disorder and other psychiatric disorders.

To investigate the cognitive functioning of children and adolescents with bipolar illness, 112 child and adolescent psychiatric inpatients and day-hospital patients at a state psychiatric hospital were administered the Wechsler Intelligence Scale for Children-III (WISC-III) as part of an admission psychological assessment. There were 22 patients with Bipolar Disorder and 90 with other psychiatric disorders; all were between 8 and 17 years of age. The patients with Bipolar Disorder had a mean age of 14 yr., a mean Verbal IQ of 78, a mean Performance IQ of 76, and a mean Full Scale IQ of 75. When their WISC-III scores were compared with those who had Schizophrenia Spectrum disorders (Schizophrenia and Schizoaffective Disorder), Psychosis Not Otherwise Specified, Attention Deficit Hyperactivity Disorder, and Conduct Disorder and Oppositional Defiant Disorder, there were no significant between-group mean differences for Verbal IQ, but patients with Bipolar Disorder had a significantly lower mean Performance IQ than those with ADHD and those with Conduct Disorder and Oppositional Defiant Disorder. Contrary to the expectation that the patients with Bipolar Disorder might have better sustained attention (higher Digit Span scores) than those with Schizophrenia Spectrum disorders and worse visual processing speed (lower Coding scores) than the other diagnostic groups, the bipolar patients' Digit Span and Coding scores did not differ significantly from those of the other groups. The patients with Psychosis, Not Otherwise Specified had significantly lower mean Performance IQ, Full Scale IQ, and Coding than the ADHD and the Conduct Disorder and Oppositional Disorder groups.

A family study of outpatients with borderline personality disorder and no history of mood disorder.

While several studies have examined psychiatric disorders in the relatives of individuals with borderline personality disorder, many of these studies have not employed a family study methodology and suffer from other methodological shortcomings. Thus, the conclusions from family data addressing the validity of borderline personality disorder, its relation to other conditions, and its distinction from mood disorders, continue to be debated. The present investigation employed a family study design with direct interviews with relatives, structured diagnostic interviews with both probands and relatives, and blind assessment of relatives. Rates of psychiatric disorders were examined in 563 relatives of outpatients with mood disorders (n = 119), 54 relatives of outpatients with borderline personality disorder and no history of mood disorder (n = 11), and 229 relatives of never psychiatrically ill controls (n = 45). Results indicate increased rates of mood disorders and personality disorders in the relatives of borderline probands compared with never psychiatrically ill controls. Familial aggregation of psychiatric disorders was generally similar for borderline personality and the mood disorder comparison group. The results suggest there may be common etiological factors between borderline personality disorder and mood disorders.
