Personality disorders and relationship to personality dimensions measured by the Temperament and Character Inventory in patients with obsessive-compulsive disorder.

The occurrence of personality disorders was investigated in 36 patients with obsessive-compulsive disorder by means of the SCID Screen questionnaire. In addition, the personality dimensions were explored by means of the Temperament and Character Inventory (TCI). In total, 75% of the patients fulfilled the criteria for a personality disorder according to the SCID Screen questionnaire, mostly (55%) within cluster C. Several significant correlations were found between the separate personality disorders (PD) and subscales of the TCI, the most pronounced being between avoidant and obsessive-compulsive PD and novelty-seeking and self-directedness. Strong correlations were also found between self-directedness and paranoid and borderline PD. In multiple regressions where the presence of PD in clusters A, B and C, respectively, were used as dependent variables and where the separate subscales of the TCI were used as independent variables, the multiple R reached 0.68, 0.76 and 0.80 in clusters A, B and C, respectively. Thus 46-64% of the variance in the personality disorder clusters could be explained by the TCI subscales.

A review of self-management interventions for panic disorders, phobias and obsessive-compulsive disorders.

OBJECTIVE: To review current evidence for the clinical and cost-effectiveness of self-management interventions for panic disorder, phobias and obsessive-compulsive disorder (OCD). METHOD: Papers were identified through computerized searches of databases for the years between 1995 and 2003, manual searches and personal contacts. Only randomized-controlled trials were reviewed. RESULTS: Ten studies were identified (one OCD, five panic disorder, four phobias). Effective self-management interventions included cognitive-behavioural therapy (CBT) and exposure to the trigger stimuli for phobias and panic disorders. All involved homework. There was evidence of effectiveness in terms of improved symptoms and psychological wellbeing when compared with standard care, waiting list or relaxation. Brief interventions and computer-based interventions were effective for most participants. In terms of quality, studies were mainly based on small samples, lacked long-term follow-up, and failed to address cost-effectiveness. CONCLUSION: Despite the limitations of reviewed studies, there appears to be sufficient evidence to warrant greater exploration of self-management in these disorders.

Somatic symptoms in generalized anxiety disorder with and without comorbid psychiatric disorders.

The authors compared the distribution of somatic symptoms associated with generalized anxiety disorder in 28 patients with "pure" generalized anxiety disorder and 77 patients with generalized anxiety disorder plus comorbid current or lifetime psychiatric diagnoses. They found no significant differences in individual symptom endorsement between the two groups, indicating that the basic symptoms of generalized anxiety disorder are specific to the disorder itself.

Generalized anxiety disorder in late life: lifetime course and comorbidity with major depressive disorder.

OBJECTIVE: Generalized anxiety disorder (GAD) in elderly persons is highly prevalent, but little is known about its course, age at onset, and relationship to comorbid major depressive disorder (MDD). The authors assessed the course and comorbidity of late-life GAD and MDD. METHODS: Authors assessed elderly subjects in anxiety or depression intervention studies who had a lifetime history of GAD, with current MDD (N=57) or without (N=46). Subjects' lifetime course of illness was charted retrospectively. RESULTS: The 103 subjects had a mean age of 74.1 years, and a mean age at onset of GAD of 48.8 years; 46% were late-onset. GAD episodes were chronic, and 36% were longer than 10 years. Of the comorbid GAD-MDD patients, most had different times of onset and/or offset of the disorders; typically, GAD preceded MDD. CONCLUSIONS: Elderly subjects with GAD tended to have chronic symptoms lasting years-to-decades, without interruption, and many have late onset. Elderly persons with lifetime GAD and MDD tend to have different onset and offset of the two disorders. Findings characterize late-life GAD as a chronic disorder distinct from MDD.

A placebo-controlled study of guanfacine in the treatment of children with tic disorders and attention deficit hyperactivity disorder.

OBJECTIVE: This study evaluated the efficacy and safety of guanfacine in treating children with tic disorders and attention deficit hyperactivity disorder (ADHD). METHOD: Subjects from a specialty tic disorders clinic were randomly assigned to receive 8 weeks of treatment with guanfacine or placebo under double-blind conditions. Follow-up visits occurred every 2 weeks for safety monitoring and dose adjustment. RESULTS: Thirty-four medication-free subjects (31 boys and three girls with a mean age of 10.4 years) with ADHD, combined type, and a tic disorder participated. After 8 weeks of treatment, guanfacine was associated with a mean improvement of 37% in the total score on the teacher-rated ADHD Rating Scale, compared to 8% improvement for placebo. Nine of 17 subjects who received guanfacine were blindly rated on the Clinical Global Improvement scale as either much improved or very much improved, compared with none of 17 subjects who received placebo. The mean score on the parent-rated hyperactivity index improved by 27% in the guanfacine group and 21% in the placebo group, not a significant difference. On the Continuous Performance Test, commission errors decreased by 22% and omission errors by 17% in the guanfacine group, compared with increases of 29% in commission errors and of 31% in omission errors in the placebo group. Tic severity decreased by 31% in the guanfacine group, compared to 0% in the placebo group. One guanfacine subject with sedation withdrew at week 4. Guanfacine was associated with insignificant decreases in blood pressure and pulse. CONCLUSIONS: Guanfacine appears to be a safe and effective treatment for children with tic disorders and ADHD.

Differences in brain chemistry in children and adolescents with attention deficit hyperactivity disorder with and without comorbid bipolar disorder: a proton magnetic resonance spectroscopy study.

OBJECTIVE: The authors' goal was to investigate phosphatidylinositol and glutamatergic metabolism in the anterior cingulate cortex of children and adolescents with attention deficit hyperactivity disorder (ADHD) alone, children with ADHD plus bipolar disorder, and children with no axis I diagnosis. METHOD: Proton spectra were acquired from a 4.8-ml voxel placed in the anterior cingulate cortex of 30 subjects who were 6 to 13 years old. Fifteen subjects had ADHD and no comorbid disorder, eight had ADHD plus bipolar disorder, and seven were healthy comparison subjects. RESULTS: Children with ADHD had a significantly higher ratio of glutamate plus glutamine to myo-inositol-containing compounds than children with ADHD plus bipolar disorder and healthy children. CONCLUSIONS: myo-Inositol-containing compounds may provide information on the action of antimanic treatments such as lithium, valproate, and carbamazepine. Glutamate and glutamine are measures of glutamatergic neurotransmission and thus may also reflect changes in serotonin and dopamine pathways.

Association between attention deficit-hyperactivity disorder and learning disorders.

This article discusses the relationship between attention deficit-hyperactivity disorder (ADHD) and learning disability (LD). The relevant literature is outlined, and empirical data are presented from a prospective follow-up study of 600 speech/language-impaired children. The data show an increased prevalence of both LD and ADHD among children with early speech/language impairments. Furthermore, LD was strongly associated with ADHD in both the initial and follow-up samples. Also, the children with LD had increased rates of other psychiatric disorders (e.g., behavior disorders, mood disorders, anxiety disorders). The implications of these data are discussed with regard to the possible etiology of the ADHD-LD association, treatment for children with LD and ADHD, and promising hypotheses for future research.

A placebo-controlled study of lofexidine in the treatment of children with tic disorders and attention deficit hyperactivity disorder.

This study evaluated the efficacy and safety of Lofexidine in treating children with tic disorders and attention deficit hyperactivity disorder (ADHD). Subjects from a specialty tic disorders clinic were randomly assigned to receive 8 weeks of treatment with lofexidine or placebo under double-blind conditions. Follow-up visits occurred every 2 weeks for safety monitoring and dose adjustment. Fourty-four medication-free subjects (41 boys and three girls; mean age of 10.4 years) with ADHD, combined type, and a tic disorder participated. After 8 weeks of treatment, lofexidine was associated with a mean improvement of 41% in the total score on the teacher-rated ADHD Rating Scale compared to 7% improvement for placebo. Eleven of 22 subjects who received lofexidine were blindly rated on the Clinical Global Scale-Improvement as either much improved or very much improved compared to none of 22 subjects who received placebo. The mean score on the parent-rated hyperactivity index improved by 29% in the lofexidine group and 18% in the placebo group, which was not a significant difference. On the Continuous Performance Test, commission errors decreased by 25% and omission errors by 20% in the lofexidine group, compared with increases of 33% in commission errors and of 36% in omission errors in the placebo group. Tic severity decreased by 27% in the lofexidine group, compared to 0% in the placebo group. One lofexidine subject with sedation withdrew at week 4. Lofexidine was associated with insignificant decreases in blood pressure and pulse. Lofexidine appears to be a safe and effective treatment for children with tic disorders and ADHD.

Recognizing and treating uncommon behavioral and emotional disorders in children and adolescents who have been severely maltreated: bipolar disorders.

Although it was assumed for many years that children do not experience bipolar disorder, it has been recently recognized that some children do. Those who have been severely maltreated may be at an increased risk for developing a bipolar disorder. This article explores the symptoms of the bipolar disorder as well as strategies for distinguishing these symptoms from those of children experiencing more common disorders. Treatment strategies, including the use of medication, for children experiencing bipolar disorder and their families are examined.

Morbidity risks of schizophrenia and affective disorders among first-degree relatives of patients with schizoaffective disorders.

Of 510 patients consecutively admitted and diagnosed as schizophrenic, 310 who failed to meet research criteria for schizophrenia were labelled as having 'atypical psychosis'. This heterogeneous group of patients was then subtyped into more homogeneous subgroupings according to their clinical characteristics, independent of their family data. One subgroup resembled schizophrenia, one resembled affective disorders and a third (n = 57), which did not resemble either schizophrenia or affective disorder, was defined as 'schizoaffective'. Comparing the morbidity risks for schizophrenic and affective disorders in the relatives of this schizoaffective group with those of the relatives of 'typical' groups of schizophrenia and affective disorder, showed that this group was different from those with schizophrenic and affective disorders.

Knowledge of social anxiety disorder relative to attention deficit hyperactivity disorder among educational professionals.

Social anxiety disorder (SAD), the 3rd most common psychiatric disorder in the United States, follows a chronic and unremitting course, often resulting in severe impairments in multiple areas of functioning. Despite a typical age of onset in early adolescence, the disorder is rarely recognized and treated in adolescent populations. Given its early age of onset, school professionals are arguably in the best position to detect symptoms of SAD and to provide appropriate referrals for assessment and intervention. This study examined the knowledge that teachers, school counselors, and school psychologists have of SAD in relation to their knowledge of a prototypical externalizing disorder, attention deficit hyperactivity disorder (ADHD). The results suggest that all 3 groups of educational professionals are surprisingly unfamiliar with adolescent SAD.

What is worse for asthma control and quality of life: depressive disorders, anxiety disorders, or both?

BACKGROUND: The high burden of asthma appears to be related to poor asthma control. Although previous studies have reported associations between depressive disorders (DDs) and anxiety disorders (ADs) and worse asthma control and quality of life, the relative impact of these disorders on asthma control and quality of life has not been explored. This study evaluated the relative impact of having a DD and/or AD on asthma control and quality of life. METHOD: Five hundred four consecutive adults with confirmed, physician-diagnosed asthma underwent a brief, structured psychiatric interview using the Primary Care Evaluation of Mental Disorders. Asthma control and asthma-related quality of life were assessed using the Asthma Control Questionnaire (ACQ) and the Asthma Quality of Life Questionnaire (AQLQ). All patients underwent standard spirometry. RESULTS: Thirty-one percent of patients (n = 157) met the diagnostic criteria for one or more psychiatric disorders (8% had DD only, 12% had AD only, and 11% had both). Analyses revealed independent effects for DDs on total ACQ scores (p < 0.01), and for DDs and ADs on total AQLQ scores and all four AQLQ subscales (p < 0.05). There were no interaction effects. CONCLUSIONS: Results suggest that DDs and ADs are associated with worse asthma-related quality of life, but only DDs are associated with worse asthma control. Interestingly, having both a DD and an AD did not confer additional risk for worse asthma control or quality of life. Physicians may want to consider the differential impact of negative mood states when assessing levels of asthma control and quality of life.

An exploration of links between early parenting experiences and personality disorder type and disordered personality functioning.

Reports of early parenting were assessed using two measures, the Parental Bonding Index (PBI) and the Measure of Parenting Style (MOPS), in a sample of 265 patients with DSM-defined major depressive disorder. Psychiatrists then rated the extent to which sample members evidenced the personality "styles" underpinning 15 separate personality disorders, returning personality vignette scores. The extent of disordered functioning was also assessed across "parameters" and "domains" by psychiatrists, referrers, and family members, using a range of measures. Those with higher scores on vignettes measuring borderline, anxious, depressive, and self-defeating personality style rated parents as uncaring, overcontrolling, and abusive. When vignettes were consolidated into scores akin to the DSM clusters, the most consistent links between perceived dysfunctional parenting were with the Cluster C (anxious), and Cluster B (dramatic) styles and were nonsignificant for Cluster A (eccentric) style. Meeting criteria for an increasing number of personality disorder clusters was associated with increasing levels of adverse parenting. Multiple regression analyses indicated that disordered functioning (as assessed by the three independent rater groups) was most distinctly associated with paternal indifference and maternal overcontrol.

Association between streptococcal infection and obsessive-compulsive disorder, Tourette's syndrome, and tic disorder.

OBJECTIVE: Reports have suggested that streptococcal infection may be etiologically related to pediatric autoimmune neuropsychiatric disorders (PANDAS), but there are few good epidemiologic studies to support this theory. Using population-based data from a large West-Coast health maintenance organization, we assessed whether streptococcal infection was associated with increased risk for obsessive-compulsive disorder (OCD), Tourette's syndrome (TS), or tic disorder. METHODS: This is a case-control study of children 4 to 13 years old receiving their first diagnosis of OCD, TS, or tic disorder between January 1992 and December 1999 at Group Health Cooperative outpatient facilities. Cases were matched to controls by birth date, gender, primary physician, and propensity to seek health care. RESULTS: Patients with OCD, TS, or tic disorder were more likely than controls to have had prior streptococcal infection (OR: 2.22; 95% CI: 1.05, 4.69) in the 3 months before onset date. The risk was higher among children with multiple streptococcal infections within 12 months (OR: 3.10; 95% CI: 1.77, 8.96). Having multiple infections with group A beta-hemolytic streptococcus within a 12-month period was associated with an increased risk for TS (OR: 13.6; 95% CI: 1.93, 51.0). These associations did not change appreciably when limited to cases with a clear date of onset of symptoms or with tighter matching on health care behavior. CONCLUSION: These findings lend epidemiologic evidence that PANDAS may arise as a result of a postinfectious autoimmune phenomenon induced by childhood streptococcal infection.

[Epidemiological study on symptoms of attention deficit/hyperactivity disorder and behavior disorders in public schools of Florianopolis/SC using the EDAH].

OBJECTIVE: Attention deficit/hyperactivity disorder (ADHD) is a pathology characterized by inattention, hyperactivity and impulsivity. The purpose of this article is to conduct an epidemiological study on symptoms of ADHA and behavior disorders in public schools of Florianopolis/SC. METHOD: The study involved 1,898 students (1,001 males and 897 females) enrolled in five public schools of Florianopolis, from the 1st up to the 4th grades, aged 6 to 12. The instrument used was the EDAH, filled out by teachers and parents, which classifies children with predominance of the following symptoms: hyperactivity, attention deficit, conduct disorder, hyperactivity with attention deficit and ADHD associated with conduct disorder (global). RESULTS: Of the 1,898 students, 95 (5%) showed symptoms of ADHA associated with behavioral disorders. Regarding gender, the prevalence was higher in boys, in a 3:1 ratio. CONCLUSION: Our data is in accordance with the literature. The distribution of the ADHD subtypes by gender is similar to the mentioned literature.

Parental bonding in men with alcohol disorders: a relationship with conduct disorder.

Men from a clinical treatment setting suffering from alcohol dependence, and randomly selected men from the community diagnosed as having alcohol abuse and/or dependence, completed the Parental Bonding Instrument. The men from the alcohol treatment setting perceived both parents as having been uncaring and overprotective. In the general population sample, an uncaring and overprotective parental style was strongly associated with childhood conduct disorder, but not with alcohol disorder symptoms. This discrepancy in perceived parenting highlights the difficulties in extrapolating findings about aetiological factors for alcohol disorders from clinical samples. It also suggests that childhood conduct disorder and adult antisocial behaviour could influence which men with alcohol disorders receive inpatient treatment.

Generalized anxiety disorder and panic disorder in the elderly: a review.

Practicing psychiatrists frequently encounter elderly patients with generalized anxiety disorder or panic disorder. Unfortunately, the empirical literature regarding the assessment, diagnosis, and treatment of these illnesses in older individuals is sparse, despite the attention directed to them in younger patients. In this paper studies of generalized anxiety and panic disorders among the elderly are reviewed and compared to similar investigations among younger adults to assess our current understanding of the epidemiology, etiology, diagnosis, and treatment of these conditions. Articles were selected from those retrieved by Index Medicus (papers in English, published in 1992 or later; search terms "anxiety," "anxiety disorders," "panic disorder," and "elderly").

The relationship between types and severity of repetitive behaviors in Gilles de la Tourette's disorder and obsessive-compulsive disorder.

BACKGROUND: This study investigated which categories of obsessive-compulsive and Tourette-related behaviors in Gilles de la Tourette's disorder and obsessive-compulsive disorder (OCD) without tics are experienced as most severe across the study groups and what the differences are in symptom distribution between the study groups. METHOD: Fourteen subjects with both Tourette's disorder and OCD, 18 subjects with Tourette's only, 21 subjects with OCD (no tics), and 29 control subjects were studied using a semistructured interview designed to equally assess Tourette- and OCD-related behaviors according to DSM-III-R criteria. Each reported repetitive behavior was evaluated on the presence of anxiety and on goal-directedness. Anxiety-related items were categorized as obsessions or compulsions and non-anxiety-related items as impulsions. Severity of each reported item was assessed with respect to time per day consumed and amount of distress and interference induced by the item. Following these criteria, each reported item was classified as a symptom, a subthreshold symptom, or just as being present. RESULTS: Across the study groups, obsessions were experienced as more severe than (Tourette-related) impulsions and compulsions. Within the study groups, patients with both Tourette's disorder and OCD reported more symptomatic Tourette-related impulsions, such as mental play, echophenomena, and impulsive or self-injurious behaviors; less overall symptomatic obsessions; and less symptomatic washing than patients with OCD (no tics). The differences among individuals with Tourette's with or without OCD reflected differences in symptom severity rather than differences in symptom distribution. CONCLUSION: Obsessions are more time consuming, distressing, and interfering than compulsions and impulsions. Furthermore, the symptomatic repetitive behaviors were distributed differently among patients with both Tourette's disorder and OCD and patients with OCD (no tics). Patients with Tourette's and OCD are phenomenologically more similar to Tourette's than to OCD. These differences possibly represent differences in underlying pathophysiology between Tourette's and tic-free OCD.
