[Familial incidence of affective diseases in patients with anorexia nervosa].

Analysis of family history information about first-, second- and third-degree relatives of 45 anorectic patients and 38 control subjects with different types of neurosis showed significantly more depression and eating disorders in the families of the anorectic group. Our data revealed the same prevalence of psychiatric disorders in general for both groups; the alcoholism rate was higher in the anorectic group without a statistic significance. These findings might provide further evidence of a possible genetic relationship between anorexia nervosa and affective illness.

[Psychopathology and clinical picture of impulsive tendencies during schizophrenia].

The author examined 60 patients with attack-form schizophrenia whose clinical picture was predominantly characterized by definite compulsions (dromomania, kleptomania, suicidomania, homicidomania, compulsive sexual disturbances, compulsion in relation to eating). Compulsions were most often first manifested at the age of 14 to 30 years. The results have shown that in the majority of cases compulsions developed in the presence of affective states in the form of melancholic, dysphoric, apathetic or adynamic depression, less commonly in the structure of affective delirious syndromes.

Genetic and environmental influences on dimensional representations of DSM-IV cluster C personality disorders: a population-based multivariate twin study.

BACKGROUND: The DSM-IV cluster C Axis II disorders include avoidant (AVPD), dependent (DEPD) and obsessive-compulsive (OCPD) personality disorders. We aimed to estimate the genetic and environmental influences on dimensional representations of these disorders and examine the validity of the cluster C construct by determining to what extent common familial factors influence the individual PDs. METHOD: PDs were assessed using the Structured Interview for DSM-IV Personality (SIDP-IV) in a sample of 1386 young adult twin pairs from the Norwegian Institute of Public Health Twin Panel (NIPHTP). A single-factor independent pathway multivariate model was applied to the number of endorsed criteria for the three cluster C disorders, using the statistical modeling program Mx. RESULTS: The best-fitting model included genetic and unique environmental factors only, and equated parameters for males and females. Heritability ranged from 27% to 35%. The proportion of genetic variance explained by a common factor was 83, 48 and 15% respectively for AVPD, DEPD and OCPD. Common genetic and environmental factors accounted for 54% and 64% respectively of the variance in AVPD and DEPD but only 11% of the variance in OCPD. CONCLUSION: Cluster C PDs are moderately heritable. No evidence was found for shared environmental or sex effects. Common genetic and individual environmental factors account for a substantial proportion of the variance in AVPD and DEPD. However, OCPD appears to be largely etiologically distinct from the other two PDs. The results do not support the validity of the DSM-IV cluster C construct in its present form.

Considerable improvement in a case of obsessive-compulsive disorder in an emotionally unstable personality disorder, borderline type under treatment with clozapine.

We report on a 27-year-old woman with previously therapy-resistant obsessive-compulsive disorder and emotionally unstable personality disorder, borderline type, which improved considerably on treatment with clozapine. Previous treatment attempts with paroxetine, clomipramine and various classic and atypical neuroleptics, as well as extensive psychotherapeutic treatment, had proved ineffective.

A comparison of DSM-III personality disorders in panic/agoraphobia and obsessive-compulsive disorder.

One hundred eighty-seven patients meeting DSM-III criteria for panic disorder (161 with agoraphobia) and 51 patients meeting DSM-III criteria for obsessive-compulsive disorder (OCD) were assessed with the Personality Diagnostic Questionnaire (PDQ), a self-rating scale designed to assess axis II personality disorders and traits. The results showed that the personality profiles were similar between the two diagnostic groups and that the major personality characteristics identified in panic/agoraphobic patients, e.g., avoidant, dependent, histrionic, and borderline, were more pronounced in patients with OCD. These findings support our earlier suggestion of a nonspecific link between panic disorder/agoraphobia and personality disorder (PD)/traits.

Gender differences in the frequency of personality disorders in depressed outpatients.

We examined gender differences in the frequency of DSM-III-R personality disorder diagnoses and symptomatology in a sample of 225 depressed outpatients. This research partially replicates and extends one of the first studies in this area by Golomb et al. (1995). Males were significantly more likely than females to meet diagnoses for schizotypal, paranoid, narcissistic, antisocial, obsessive compulsive, and borderline personality disorder. Compared to females, males were also significantly more likely to have schizoid, schizotypal, narcissistic, antisocial, and obsessive-compulsive personality disorder symptomatology. Females did not predominate in any personality disorder symptomatology or diagnoses. A possible explanation for these findings is discussed. The results of this study challenge traditional assumptions about gender differences in the frequency of personality disorders, and confirm the need for future studies to investigate the relation between gender and personality disorders in specific Axis I samples.

The hoarding dimension of OCD: psychological comorbidity and the five-factor personality model.

Although hoarding has been associated with several psychological disorders, it is most frequently linked to obsessive-compulsive disorder (OCD). The present study assessed hoarding obsessions and compulsions in 204 individuals with OCD, and evaluated how hoarding was related to obsessive-compulsive symptom severity, psychological comorbidity, and personality as measured by the five-factor model. Results indicated that hoarding in OCD is a dimensional variable that is positively associated with dysphoria, total number of lifetime Axis I disorders, and lifetime histories of bipolar I, PTSD, and body dysmorphic disorder. Hoarding was negatively correlated with the NEO-Personality Inventory-Revised (NEO-PI-R) factor of Conscientiousness and positively associated with the NEO-PI-R factor of Neuroticism. When all personality and psychopathology variables were entered into a regression equation, dysphoria, bipolar II disorder, Conscientiousness, age, and Extraversion emerged as significant predictors of hoarding severity. Recommendations are made for clinicians and for future research.

Personality disorders in patients with obsessive-compulsive disorder in Japan.

A total of 75 patients with obsessive-compulsive disorder (OCD) were studied in order to investigate the characteristics of OCD symptoms and the comorbidity of personality disorders (PD). Contamination obsessions and checking compulsions were most commonly found in patients, of whom 53% met the criteria for at least one PD. Among comorbid PD, the anxious-fearful (cluster C) PDs, such as avoidant, obsessive-compulsive and dependent PD, were most prevalent, followed by the odd-eccentric (cluster A) PDs, such as paranoid and schizotypal PD. The patients with PD had more severe social maladaptation and concurrent depressive and anxious symptoms than the patients without any PD, despite the similar severity of OCD symptoms. These results are consistent with those reported in the Western world, and are considered to be relatively stable cross-culturally.

Predictors of drug treatment response in obsessive-compulsive disorder.

BACKGROUND: Although a large body of evidence indicates the efficacy of pharmacotherapy in the treatment of obsessive-compulsive disorder (OCD), a considerable percentage of these patients do not respond. Very few studies focus on factors related to treatment response of OCD. The purpose of this study was to investigate which clinical factors are related to drug treatment response in OCD. METHOD: We examined 53 OCD patients treated with either clomipramine or fluoxetine for a period of 6 months, dividing the sample into "responders" and "nonresponders" to treatment. At admission, patients were evaluated using a semistructured clinical interview, the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), the Hamilton Rating Scale for Depression, and the Hamilton Rating Scale for Anxiety. We then compared acute-phase patient characteristics and response to drug treatment. Response was defined as a decrease of at least 40% in the Y-BOCS total score and a rating of "improved" or "very improved" on the Clinical Global Impressions scale within 16 weeks of treatment and maintained over three consecutive evaluations. RESULTS: By the sixth month of treatment, 31 patients (58.5%) responded to either clomipramine or fluoxetine. Nonresponders had lower age at onset and longer duration of the disorder; in addition, they showed higher frequency of compulsions, washing rituals, chronic course, concomitant schizotypal personality disorder, and previous hospitalizations. A worse response to drug treatment was predicted in a stepwise multiple regression by (1) concomitant schizotypal personality disorder, (2) presence of compulsions, and (3) longer illness length. CONCLUSION: Our findings suggest that there are distinct types of OCD with respect to drug treatment response. They provide indirect evidence of treatment specificity by identifying characteristics responsive to different modalities, which may be of value in the selection of patients for alternative treatments.

Hoarding in obsessive compulsive disorder: results from a case-control study.

Hoarding occurs relatively frequently in obsessive-compulsive disorder (OCD), and there is evidence that patients with hoarding symptoms have more severe OCD and are less responsive to treatment. In the present study, we investigated hoarding symptoms in 126 subjects with OCD. Nearly 30% of the subjects had hoarding symptoms; hoarding was twice as prevalent in males than females. Compared to the 90 non-hoarding subjects, the 36 hoarding individuals had an earlier age at onset of, and more severe, obsessive-compulsive symptoms. Hoarders had greater prevalences of symmetry obsessions, counting compulsions, and ordering compulsions. Hoarders also had greater prevalences of social phobia, personality disorders, and pathological grooming behaviors (skin picking, nail biting, and trichotillomania). Hoarding and tics were more frequent in first-degree relatives of hoarding than non-hoarding probands. The findings suggest that the treatment of OCD patients with hoarding symptoms may be complicated by more severe OCD and the presence of co-occurring disorders. Hoarding appears to be transmitted in some OCD families and may differentiate a clinical subgroup of OCD.
