[Attention deficit disorder and anxiety disorders: a co-occurrence study].

Recent epidemiological studies have evaluated the concomitant occurrence of several disorders in children. Over the last few years there have been reports from Anglo-Saxon investigators that many children with attention deficit disorder-hyperactivity also have anxiety disorders. This is the first French study addressing this issue. The prevalence and types of anxiety disorders were determined in 50 children with attention deficit disorder-hyperactivity using a questionnaire and a semi-structured interview. Over 40% of subjects had at least one concomitant anxiety disorder meeting DSM-III-R criteria. Hyperanxiety and separation anxiety were the most common anxiety disorders. Among patients with anxiety, over 40% had more than one anxiety disorder. These data are consistent with earlier Anglo-Saxon reports. Symptoms of anxiety which discriminated hyperactive children with and without anxiety disorders were identified.

Major mental disorder and antisocial personality disorder: a criminal combination.

Much evidence now suggests that patients with major mental disorders are at increased risk for crimes and violence. Leading experts in forensic psychiatry have proposed that the illegal behaviors are a consequence of these major disorders. Yet, longitudinal studies have consistently indicated that adult criminality is preceded by a childhood history of antisocial behavior. We hypothesized that among offenders with major mental disorders there are two groups: (1) the first group has a secondary diagnosis of antisocial personality disorder (APD), and a childhood history of antisocial and criminal behavior preceding the onset of the major disorder; (2) the second group do not meet the criteria for APD, and behave criminally only as adults. This hypothesis was tested on a representative sample of penitentiary inmates with major mental disorders. It was found that those with APD had a significant childhood history of criminal activity and antisocial behavior, endorsing, on average, eight of ten possible indices. In comparison, the mentally disordered inmates without APD endorsed on average two indices. The mentally disordered offenders with APD began their criminal careers earlier, and had significantly more convictions and more convictions for nonviolent offenses than those without APD. APD was not associated with violence among men with major mental disorders.

Effects of panic disorder treatments on personality disorder characteristics.

Ninety-three patients with panic disorder and mild or no agoraphobia were treated for their panic disorder by using either 11 sessions of individual cognitive-behavior therapy or imipramine. Before and after treatment, their panic disorder symptomatology was assessed, and a self-report measure was administered to measure personality disorder characteristics [Klein et al., 1990: Wisconsin Personality Disorders Inventory]. In addition, some patients received this personality assessment again after six monthly maintenance sessions. Both treatments were equally effective in reducing panic disorder symptomatology, and both treatments had a positive influence on personality disorder characteristics. Personality disorder characteristics did not predict treatment outcome in either group. The implications of the findings for the assessment of personality and the treatment of panic disorder are discussed.

Diagnostic interview assessed neuropsychiatric disorder comorbidity in 334 individuals with obsessive-compulsive disorder.

Is obsessive-compulsive disorder (OCD) a discrete disorder? Three hundred thirty-four individuals with OCD were interviewed using the Structured Clinical Interview for DSM (SCID). Results demonstrate that OCD is highly comorbid with other neuropsychiatric disorders, with 92% of OCD study participants receiving one or more additional Axis I DSM diagnoses. Among these additional diagnoses, lifetime mood disorders (81%) and anxiety disorders (53%) were the most prevalent. With the exception of substance-related disorders and specific phobias, all disorders assessed were found in considerably higher frequency than in the general population, indicating that OCD is associated with highly complex comorbidity. These data have implications for genetic studies of OCD and disorders related to OCD, as well as for specific psychotherapeutic and psychopharmacologic interventions.

Prevalence of personality disorders among patients with anxiety disorders.

Outpatients with a principal diagnosis of an anxiety disorder (n = 347) were administered the Structured Clinical Interview for DSM-III-R/Axis II Disorders (SCID-II) during their intake evaluation. At least one personality disorder was found in 35% of these patients. Patients with social phobia (61%) and generalized anxiety disorder (49%) were most often diagnosed with a personality disorder. Patients with simple phobia were rarely diagnosed with a personality disorder (12%). The most commonly diagnosed personality disorders were from the "anxious/fearful" cluster (27% received at least one diagnosis from cluster C), most notably avoidant and obsessive-compulsive personality. Our findings suggest that personality disorders, in general, are less prevalent among anxious patients than among depressive patients.

Borderline personality disorder characteristics in young adults with recurrent mood disorders: a comparison of bipolar and unipolar depression.

BACKGROUND: In young adults it can be difficult to differentiate between an early bipolar illness and borderline personality disorder. There are considerable areas of clinical overlap between cyclothymic temperament, bipolar-spectrum disorders and borderline characteristics. The aim of this study was to measure borderline characteristics in young adults during an index depressive episode and to compare three diagnostic groups: DSM-IV bipolar affective disorder (BPAD); bipolar spectrum disorder (BSD); and DSM-IV recurrent major depressive disorder (MDD). METHODS: Eighty-seven young adults with a current episode of major depression and at least one previous episode of depression were recruited from consecutive referrals to a psychiatric clinic. Diagnoses were based on the Structured Clinical Interview for DSM-IV (SCID-1) and recently proposed structured diagnostic criteria for BSD. All patients also completed the borderline questions from the screening questionnaire of the International Personality Disorders Examination (IPDE). RESULTS: Diagnostically, the cohort of 87 patients divided into three groups: 14 with BPAD; 27 with BSD; and 46 with MDD. None of the subjects fulfilled DSM-IV or ICD-10 diagnostic criteria for personality disorder and all three groups were well matched in terms of age, gender distribution, ethnicity, socioeconomic and educational status, age at onset of illness, and severity of index depressive episode. Both of the bipolar-depressed groups reported significantly higher median levels of borderline characteristics than the MDD group (p<0.0001). Three of the borderline characteristics emerged as potentially useful in differentiating bipolar depression from unipolar depression: 'I've never threatened suicide or injured myself on purpose' (sensitivity=0.93; positive predictive value [PPV]=56.7); 'I have tantrums or angry outbursts' (sensitivity 0.66; PPV=65.6%); and 'Giving in to some of my urges gets me into trouble' (sensitivity=0.76; PPV=59.6%). LIMITATIONS: All of the subjects were recruited from a university health service clinic and as such are unlikely to be representative of patients from more diverse socio-economic backgrounds. No structured diagnostic assessment of personality disorder was administered. The diagnostic criteria for BSD are not yet fully validated. CONCLUSIONS: Young adults with bipolar depression exhibit significantly higher levels of borderline personality pathology than those with unipolar depression. Those borderline screening questions that reflect cyclothymic characteristics or depressive mixed states may be of practical use to clinicians in helping to differentiate between bipolar depression and unipolar depression in young adults.

Externalizing disorders in consecutively referred children and adolescents with bipolar disorder.

We describe a consecutive clinical sample of children and adolescents with bipolar disorder (BD), in order to define the pattern of comorbid externalizing disorders and to explore the possible influence of such a comorbidity on their cross-sectional and longitudinal clinical characteristics. The sample consisted of 59 bipolar patients: 35 males and 24 females, with a mean age 14.6 +/- 3 years (range, 7 to 18 years), diagnosed as either type I or II according to DSM-IV. All patients were screened for psychiatric disorders using historical information and a clinical interview, the Diagnostic Interview for Children and Adolescents-Revised (DICA-R). Severity and subsequent outcome of the symptomatology were recorded with the Clinical Global Impression (CGI), Severity and Improvement Scales, at the baseline and thereafter monthly for a period up to 48 months. BD disorder type I was present in 37 (62.7%) of the patients; 14 (23.7%) were affected by attention deficit-hyperactivity disorder (ADHD) and 10 (16.9%) by conduct disorder (CD). Comorbid ADHD was associated with an earlier onset of BD, while CD was highly associated with BD type I. Anxiety disorders appeared more represented in patients without CD. At the end of the observation, a lower clinical improvement was recorded in patients with CD. In our children and adolescents with BD, comorbidity with externalizing disorders such as ADHD and CD is common. The clinical implications of comorbid ADHD and CD are rather different. ADHD can be viewed as a precursor of a child-onset subtype of BD, while CD might represent a prodromal or a concomitant behavioral complication that identifies a more malignant and refractory form of BD.

Dissociative disorders in Turkish inpatients with conversion disorder.

The aim of our study was to determine the frequency of dissociative disorders (DDs) among inpatients with conversion disorder (CD) in a university clinic settled in Eastern Turkey. During a period of 24 months, 59 consecutively admitted adult CD patients were screened with the Dissociative Experience Scale (DES). Patients who scored above 30 (DDs group) did not differ by age or gender from a group of inpatients who scored below 10 on the scale (comparison group). All patients in the two groups were then interviewed in a blind manner using the Dissociative Disorders Interview Schedule (DDIS) and Structured Interview for DSM-IV Dissociative Disorders (SCID-D). According to the SCID-D, 18 of 59 patients (30.5%) received a diagnosis of dissociative disorder; nine of these 18 patients (50%) were diagnosed as having dissociative identity disorder, eight (44.4%) were diagnosed as having dissociative disorder not otherwise specified (NOS), and one (5.6%) was diagnosed as having dissociative amnesia. Accordingly to the DDIS, borderline personality disorder was frequent in the DDs group, and all of the patients in the DDs group reported sexual abuse and neglect during childhood, latency, or adolescence. A high proportion of CD patients have significant dissociative pathology. The proper diagnosis of these patients has important implications for their clinical course.

Depressive personality in the relatives of outpatients with dysthymic disorder and episodic major depressive disorder and normal controls.

BACKGROUND: This study examined whether there is a familial relationship between depressive personality and the mood disorders. METHOD: Rates of depressive personality were compared in 161 relatives of outpatients with dysthymic disorder (DD), 75 relatives of outpatients with non-chronic major depressive disorder (MDD), and 90 relatives of normal controls. All probands and relatives were evaluated using structured diagnostic interviews for Axis I disorders and depressive personality traits. RESULTS: The relatives of patients with DD exhibited a significantly higher rate of depressive personality than the relatives of normal controls, while the relatives of patients with MDD fell in between, and did not differ from, the other two groups. These results held after controlling for a lifetime history of mood disorder in the relatives, and could not be explained by an increased rate of depressive personality in the DD probands. LIMITATIONS: The sample size was modest, comorbid non-mood Axis I and II disorders in the relatives were not controlled, and DSM-IV criteria for depressive personality disorder were not yet available at the time the study was undertaken. CONCLUSION: These findings are consistent with the view that depressive personality is part of a spectrum of mood disorders with a shared familial liability, but suggest that this link is strongest with chronic forms of depression such as DD and double depression.

Differences in finger length ratio between males with autism, pervasive developmental disorder-not otherwise specified, ADHD, and anxiety disorders.

Children with autism have a relatively shorter index finger (2D) compared with their ring finger (4D). It is often presumed that the 2D:4D ratio is associated with fetal testosterone levels and that high fetal testosterone levels could play a role in the aetiology of autism. It is unknown whether this effect is specific to autism. In this study, 2D:4D ratios of 144 males aged 6 to 14 years (mean age 9y 1 mo [SD 1y 11 mo]) with psychiatric disorders were compared with those of 96 males aged 6 to 13 years from the general population (mean age 9y 1 mo [SD 1y 10 mo]). Psychiatric disorders were divided into autism/Asperger syndrome (n=24), pervasive developmental disorder-not otherwise specified (PDD-NOS; n=26), attention-deficit-hyperactivity disorder (ADHD)/oppositional defiant disorder (ODD; n=68), and anxiety disorders (n=26). Males with autism/Asperger syndrome (p<0.05) and ADHD/ODD (p<0.05) had significantly lower (though not significantly; p=0.52) ratios than males with an anxiety disorder, and males with autism/Asperger syndrome had lower ratios than those in the comparison group. These results indicated that higher fetal testosterone levels may play a role, not only in the origin of autism, but also in the aetiology of PDD-NOS and of ADHD/ODD. Males with anxiety disorders might have been exposed to lower prenatal testosterone levels.

Separation of DSM-III attention deficit disorder and conduct disorder: evidence from a family-genetic study of American child psychiatric patients.

Using family study methodology and assessments by blind raters, this study tested hypotheses about patterns of familial association between DSM-III attention deficit disorder (ADD) and antisocial disorders (childhood conduct (CD) and oppositional disorder (OPD) and adult antisocial personality disorder) among 457 first-degree relatives of clinically referred children and adolescents with ADD (73 probands, 264 relatives), psychiatric (26 probands, 101 relatives) and normal controls (26 probands, 92 relatives). Among the 73 ADD probands, 33 (45%) met criteria for OPD, 24 (33%) met criteria for CD, and 16 (22%) had no antisocial diagnosis. After stratifying the ADD sample into those with CD (ADD + CD), those with OPD (ADD + OPD) and those with neither (ADD) familial risk analysis revealed the following: (1) relatives of each ADD proband subgroup were at significantly greater risk for ADD than relatives of both psychiatric and normal controls: (2) the morbidity risk for ADD was highest among relatives of ADD + CD probands (38%), moderate among relatives of ADD + OPD (17%) and ADD probands (24%) and lowest among relatives of psychiatric and normal controls (5% for both); (3) the risk for any antisocial disorder was highest among relatives of ADD + CD (34%) and ADD + OPD (24%) which were significantly greater than the risk to relatives of ADD probands (11%), psychiatric (7%) and normal controls (4%); and (4) both ADD and antisocial disorders occurred in the same relatives more often than expected by chance alone. Although these findings suggest that ADD with and without antisocial disorders may be aetiologically distinct disorders, they are also consistent with a multifactorial hypothesis in which ADD, ADD + OPD and ADD + CD fall along a continuum of increasing levels of familial aetiological factors and, correspondingly, severity of illness.

Behavioral and developmental disorders among conduct disorder.

The purpose of the present study was to clarify the percentage of children with conduct disorder (CD) who also have behavioral and developmental disorders. A survey of comorbidity observed in children with CD, was carried out on 33 subjects from a disciplinary facility for children. Female teachers as the mother were interviewed as regards the subjects' condition using the semistructured interview, and male teachers as the father were interviewed for their psychosocial problems. The subjects underwent the Wechsler Intelligence Scale for Children (WISC)-III and their conditions were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV). Of the 33 children, 27 were diagnosed as having CD. Of the 27 CD children, 18 (67%) were diagnosed as having attention deficit hyperactivity disorder (ADHD), and 19 (70%) had oppositional defiant feature (ODF). Eight children (30%) were diagnosed as having mental retardation and in seven children (26%), the verbal IQ was significantly lower than the performance IQ. Two (7%) were diagnosed as having pervasive developmental disorders (PDD). Of 27 children diagnosed with CD, 23 (85%) had some behavioral and developmental disorders. The classification of these behavioral and developmental disorders into the following three types appeared to be clinically useful: type 1, ADHD and ODF; type 2, low intelligence, especially low verbal intelligence; and type 3, PDD. To understand and treat children with CD, the accurate diagnosis of these underlying behavioral and developmental disorders is indispensable.

Frequency of comorbid personality disorders in bipolar and unipolar affective disorders.

One expression of the complex relationship between personality and affective disorder is the comorbidity of personality disorders (PDs) with affective disorders. In a sample of 117 patients with unipolar and 60 with bipolar affective disorders, we assessed DSM-III-R PDs with the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II) and compared them with personality factors as obtained by the five-factor model (FFM-NEO Five-Factor Inventory). Fifty-one percent of the unipolar and 38% of the bipolar disorders fulfilled criteria for a comorbid PD. The three most frequent PDs were obsessive-compulsive PD, borderline PD, and narcissistic (bipolar) or avoidant (unipolar) PD. Cluster C PDs and especially avoidant PD occurred significantly more frequently in unipolar than in bipolar patients, while narcissistic PD occurred significantly more often in bipolar than in unipolar patients. The FFM results supported the validity of our PD diagnoses. In a logistic regression analysis, higher depression score at the time of the SCID-II interview and shorter duration of the illness were weakly related to a higher frequency of PDs. Our results indicate that PDs are frequent in affective disorders and that there are subtle differences between unipolar and bipolar patients concerning such comorbid disorders.

Bipolar II affective disorder in eating disorder inpatients.

We examined the association between affective disorders and eating disorders in 22 eating disorder inpatients who were interviewed using the Schedule for Affective Disorders and Schizophrenia-Lifetime Version. The first series of 11 were interviewed as part of an interrater reliability study; the second series, done as follow-up to the first, consisted of 11 consecutive admissions. Overall, there were 15 bulimics and seven anorexics. Nineteen patients had a major affective disorder, and 13 (59%) had bipolar II affective disorder. Bipolar II affective disorder appears to be a common finding in hospitalized patients with severe persistent eating disorders.

Attention deficit hyperactivity disorder and comorbid disorders: issues of overlapping symptoms.

OBJECTIVE: Since some symptoms are shared by both attention deficit hyperactivity disorder (ADHD) and comorbid psychiatric conditions, it is possible that a diagnosis of ADHD is an artifact of the overlapping symptoms. This article focuses on the assessment of the influence of overlapping symptoms on the diagnosis of ADHD. METHOD: Three groups of subjects were studied: a group of clinically referred children and adolescents, a group of nonreferred adults who were the parents of these children and adolescents, and a group of clinically referred adults with ADHD. The authors assessed the extent of symptom overlap between ADHD and the disorders that frequently co-occur with ADHD; major depression, bipolar disorder, and generalized anxiety disorder. To determine the degree to which this symptom overlap influences these diagnoses, each individual was rediagnosed on the basis of two different techniques that corrected for the overlapping symptoms, a subtraction method and a proportion method. RESULTS: The majority of subjects who had both ADHD and a comorbid psychiatric disorder maintained their diagnosis of ADHD when the overlapping symptoms were subtracted. Moreover, when overlapping ADHD symptoms were subtracted, on average, 79% maintained their diagnosis of major depression, 56% maintained their diagnosis of bipolar disorder, and 75% maintained their diagnosis of generalized anxiety disorder. CONCLUSIONS: These findings show that ADHD is not an artifact of symptoms shared with other psychiatric disorders and that the comorbid conditions themselves are not an artifact of overlapping ADHD symptoms.

Acute stress disorder, posttraumatic stress disorder, and depression in disaster or rescue workers.

OBJECTIVE: The events of Sept. 11, 2001, highlighted the importance of understanding the effects of trauma on disaster workers. To better plan for the health care of disaster workers, this study examined acute stress disorder, posttraumatic stress disorder (PTSD), early dissociative symptoms, depression, and health care utilization in disaster workers. METHOD: Exposed disaster workers (N=207) and unexposed comparison subjects (N=421) were examined at 2, 7, and 13 months after an airplane crash. RESULTS: Exposed disaster workers had significantly higher rates of acute stress disorder, PTSD at 13 months, depression at 7 months, and depression at 13 months than comparison subjects. Those who were younger and single were more likely to develop acute stress disorder. Exposed disaster workers with acute stress disorder were 3.93 times more likely to be depressed at 7 months. Those with high exposure and previous disaster experience or who had acute stress disorder were more likely to develop PTSD. Similarly, those who were depressed at 7 months were 9.5 times more likely to have PTSD. Those who were depressed at 13 months were 7.96 times more likely to also meet PTSD criteria. More exposed disaster workers than comparison subjects obtained medical care for emotional problems at 2, 7, and 13 months. Overall, 40.5% of exposed disaster workers versus 20.4% of comparison subjects had acute stress disorder, depression at 13 months, or PTSD. CONCLUSIONS: Exposed disaster workers are at increased risk of acute stress disorder, depression, or PTSD and seek care for emotional problems at an increased rate.

Acute stress disorder and posttraumatic stress disorder in children and adolescents involved in assaults or motor vehicle accidents.

OBJECTIVE: The authors investigated acute stress disorder and later posttraumatic stress disorder (PTSD) in children and adolescents who had been involved in assaults or motor vehicle accidents. METHOD: They interviewed 93 patients 10-16 years old who were seen in an emergency department for having been assaulted or involved in a motor vehicle accident within 4 weeks after the assault or accident to assess acute stress disorder. At 6 months, they reinterviewed 64 (68.8%) of the patients to assess PTSD. RESULTS: At initial interview, 18 (19.4%) of the 93 patients had acute stress disorder and 23 (24.7%) met all acute stress disorder criteria except dissociation. At 6 months, eight of the 64 patients (12.5%) had PTSD. Acute stress disorder and PTSD did not differ in prevalence between patients who had been assaulted and those who had been in accidents. Sensitivity and specificity statistics and regression modeling revealed that the diagnosis of acute stress disorder was a good predictor of later PTSD but that dissociation did not play a significant role. CONCLUSIONS: Acute stress disorder has merit as a predictor of later PTSD in children and adolescents, but dissociation has questionable utility.

Psychotic symptoms in patients with borderline personality disorder and concurrent axis I disorder.

OBJECTIVE: Whether psychotic symptoms are part of the fundamental psychopathology of borderline personality disorder remains in dispute. The goal of the study was to examine the incidence and nature of psychotic symptoms in a sample of patients with the disorder. METHODS: The inpatient psychiatric records of 92 patients with a discharge diagnosis of borderline personality disorder, some of whom had comorbid affective disorder or substance abuse disorder, were examined to obtain data on the presence of psychotic symptoms (narrowly defined as delusions and auditory and visual hallucinations), the duration of psychotic episodes, and the clinical characteristics of the patients. RESULTS: Twenty-seven percent of the patients had psychotic episodes, typically lasting many weeks. Comorbid affective or substance abuse disorders did not predict psychotic symptoms. CONCLUSIONS: Psychotic episodes are common but not universal among patients with borderline personality disorder, regardless of whether a concurrent axis I disorder is present. Those episodes are not necessarily brief or transient, and borderline patients who experience psychotic episodes are likely to have repeated hospitalizations.
