Co-occurrence of personality disorders in persons with kleptomania: a preliminary investigation.

This study was conducted to examine the co-occurrence of personality disorders in a group of persons with kleptomania. Twenty-eight subjects with DSM-IV kleptomania were administered the Structured Clinical Interview for DSM-III-R Personality Disorders and a semistructured interview to assess demographics and clinical characteristics. Twelve subjects with kleptomania (42.9%) met criteria for at least one personality disorder. The most common were: paranoid (n = 5; 17.9%), schizoid (n = 3; 10.7%), and borderline (n = 3; 10.7%). Subjects with kleptomania combined with personality disorders had an earlier age of onset of stealing behavior (13.4 +/- 5.6 years compared with 27.4 +/- 14.2 years in those who had kleptomania only; t = 3.225; df = 26; p = .006). Severity of kleptomania symptoms did not differ among the Axis II comorbidities. Persons with kleptomania appear to have a high prevalence of personality disorders. Further studies are needed to understand the relationship of kleptomania to personality.

[Attention and executive processes in neuropsychological rehabilitation of the visuospatial processes].

INTRODUCTION AND OBJECTIVE: Cognitive deficits following lesions in parieto occipital areas tend to cause, among others, visuospatial and visuoperceptive alterations. The aim of this article is to examine the influence of others possible deficit over its rehabilitation. DEVELOPMENT: We discuss several patients who present visuospatial impairment after different brain injuries, not only those affecting the areas typically involved in these deficits, such as parieto occipital cortex. Rehabilitation was conducted on an individual basis in the brain injury unit of Beata Maria Ana hospital. Neuropsychological evaluation showed some difficulties not previously described together with these deficits, related to attention, working memory and executive functions, as well as topographic disorientation, lack of visuospatial coordination, distances perception disorders and difficulty to mentally rotate objects. The rehabilitation was AIMed not only at restoration but also compensation of visuospatial deficits, successfully achieved after treatment: patients were capable of returning to their daily activities, including their jobs. CONCLUSION: In patients with visuospatial deficits, a compressive neuropsychological evaluation seem to be essential to define the influence of the other cognitive domains over the rehabilitation of visuospatial problems. In particular, the reinforcement of processes related to attention control and executive functions could very important, give their contribution to the learning of compensatory strategies and assuming that those functions pay key role in the organization and supervision demanded for perceptual skills.

A family study of pathological gambling.

The cause of pathological gambling (PG) is unknown. The current study was conducted to determine whether PG is familial, and to examine patterns of familial aggregation of psychiatric disorder. To that end, 31 case probands with DSM-IV PG and 31 control probands were recruited and interviewed regarding their first degree relatives (FDRs). Available and willing FDRs were directly interviewed with structured instruments of known reliability, and best estimate final diagnoses were blindly assigned for 193 case and 142 control relatives over age 18 years. The results were analyzed using logistic regression by the method of generalized estimating equations. The lifetime rates of PG and "any gambling disorder" were significantly greater among the relatives of case probands (8.3% and 12.4%, respectively) than among the control relatives (2.1% and 3.5%, respectively) (OR=3.36 for "any gambling disorder"). PG relatives also had significantly higher lifetime rates of alcohol disorders, "any substance use disorder," antisocial personality disorder (ASPD), and "any mental disorder". "Any gambling disorder," alcohol disorder, and "any substance use disorder" remained significant after a conservative Bonferroni correction. Interestingly, PG families were significantly larger than control families. We conclude that gambling disorders are familial and co-aggregate with substance misuse. The data are also suggestive that PG co-aggregates with ASPD. Further research on the heritability of PG is warranted.

Depression and suicidal behavior in adolescent inpatients with obsessive compulsive disorder.

BACKGROUND: To investigate the prevalence and correlations of suicidal behavior in obsessive compulsive disorder (OCD) among adolescent psychiatric inpatients. METHODS: A total of 348 adolescents, representing consecutive admissions to an adolescent inpatient unit, were assessed. Of these, 40 patients had OCD, 118 had schizophrenia, 59 had an affective disorder, 81 had a conduct disorder and 50 had an eating disorder. In addition, 87 normal community controls were assessed. All subjects were assessed for suicidal behavior by the Childhood Suicide Potential Scale (CSPS), for depression by the Beck Depression Inventory, for impulsiveness by the Impulse Control Scale, for anxiety by the State-Trait Anxiety Scale and for aggression by the Yudowsky Overt Aggression Scale. RESULTS: All the psychiatrically ill subjects, including those with OCD, had high levels of depression, anxiety and impulsiveness, which were far higher than those of the controls. The rate of attempted suicide was, however, much lower in the OCD subjects. In addition, there was a significant inverse correlation between suicidal behavior levels on the CSPS and depression in the OCD subjects, while all other subjects showed the expected significant positive correlation between level of suicidal behavior and depression. LIMITATIONS: This study looked at a referred population and generalization to outpatient and community samples cannot be made. Distinguishing between the primary and the comorbid diagnosis is difficult and some findings are based on small sample size and therefore may be vulnerable to type I error. CONCLUSIONS: Although suicidal ideation and depressive symptoms are common in OCD adolescent inpatients, they seem to be protected against suicide attempts. The inverse relationship between suicidal behavior and depression may mean that suicidal behavior is, in some ways, qualitatively different from that seen in other psychiatrically ill adolescents.

Citalopram for compulsive shopping disorder: an open-label study followed by double-blind discontinuation.

BACKGROUND: Open-label trials suggested that fluvoxamine and citalopram may be effective for compulsive shopping disorder, but 2 double-blind fluvoxamine trials failed to confirm this. To test the hypothesis that citalopram is a safe, effective treatment for this disorder, we conducted a 7-week, open-label trial followed by a 9-week, double-blind, placebo-controlled discontinuation trial. METHOD: From Jan. 2001 to Jan. 2002, we enrolled adult outpatients meeting diagnostic criteria suggested in a prior study for compulsive shopping disorder and having a score of >/= 17 on the Yale-Brown Obsessive Compulsive Scale-Shopping Version (YBOCS-SV). Open-label citalopram was started at 20 mg/day and increased, absent marked response and limiting side effects, to 60 mg/day. Responders (subjects rated "much improved" or "very much improved" on the Clinical Global Impressions-Improvement scale [CGI-I] and having a >/= 50% decrease in YBOCS-SV score) were randomized to double-blind citalopram treatment at the week 7 dose or placebo for 9 weeks. RESULTS: We enrolled 24 subjects (23 women and 1 man). Mean +/- SD YBOCS-SV scores decreased significantly from 24.3 +/- 4.6 at baseline to 8.2 +/- 8.1 at week 7 (Wilcoxon signed rank: z = 4.20, p <.001). Fifteen of 24 subjects (63%) met the responder criteria. Three subjects (13%) discontinued for adverse events (1 each for headache, rash, and insomnia). Of the 15 responders who entered the double-blind treatment phase, 5 of 8 (63%) randomized to placebo relapsed (YBOCS-SV score >/= 17 and "minimally improved" or less on the CGI-I) compared with none of 7 randomized to continue taking citalopram (Fisher exact test p =.019). CONCLUSION: Citalopram appears to be a safe and effective treatment for compulsive shopping disorder. Further trials of citalopram and other selective serotonin reuptake inhibitors are warranted.

Neurobehavior disinhibition in childhood predisposes boys to substance use disorder by young adulthood: direct and mediated etiologic pathways.

OBJECTIVE: The development of substance use disorder (SUD) was prospectively investigated in 66 boys having fathers with SUD and 104 boys having fathers with no adult Axis I or II psychiatric disorder. Evaluations were conducted to determine the context in which neurobehavior disinhibition in relation to parental SUD, parental neglect of the child and child's social maladjustment culminated in a DSM-III-R diagnosis of SUD. METHODS: A neurobehavior disinhibition latent trait was derived using indicators of behavior undercontrol, affect dysregulation and executive cognitive functioning in the boys when they were 10-12 and again at 16 years of age. These latter characteristics have been frequently observed in individuals who have a prefrontal cortex disturbance. The data were analyzed to determine whether the score on the neurobehavior disinhibition construct mediates the association between father's and mother's SUD and son's SUD. RESULTS: SUD in the mother and father predicted neurobehavior disinhibition in the son. The neurobehavior disinhibition score in the sons predicted SUD between ages 10-12 and 19. Neurobehavior disinhibition, in conjunction with social maladjustment and drug use frequency, mediated the association between paternal and maternal SUD and son's SUD. Neurobehavior disinhibition was unrelated to neglect of the child by either the father or mother; however, paternal but not maternal neglect at age 10-12 predicted SUD at age 19. CONCLUSIONS: The association of neurobehavior disinhibition in childhood and SUD by young adulthood suggests that a prefrontal cortex dysfunction contributes to SUD liability. The results extend previous findings demonstrating that neurobehavior disinhibition is an important component of the liability to SUD.

Pathological gambling. A psychobiological study.

We investigated psychobiological substrates of pathological gambling by measuring levels of norepinephrine, monoamine metabolites, and peptides in cerebrospinal fluid, plasma, and urine. Pathological gamblers had a significantly higher centrally produced fraction of cerebrospinal fluid levels of 3-methoxy-4-hydroxyphenylglycol as well as significantly greater urinary outputs of norepinephrine than controls. These results suggest that pathological gamblers may have a functional disturbance of the noradrenergic system. This system has been postulated to underlie sensation-seeking behaviors, aspects of which are thought to be abnormal among pathological gamblers.

Relationship of psychobiological variables to recidivism in violent offenders and impulsive fire setters. A follow-up study.

Fifty-eight violent offenders and impulsive fire setters were followed up for an average of 3 years after release from prison. Recidivists who committed a new violent offense or arson had significantly lower cerebrospinal fluid 5-hydroxyindoleacetic acid and homovanillic acid concentrations and blood glucose nadirs after oral glucose challenge than did nonrecidivists. A discriminant analysis, based on the blood glucose nadir and cerebrospinal fluid 5-hydroxyindoleacetic acid concentration, correctly classified 84.2% of the subjects.

Suicidality and 5-hydroxyindoleacetic acid concentration associated with a tryptophan hydroxylase polymorphism.

BACKGROUND: To examine whether the tryptophan hydroxylase (TPH) gene, which codes for the rate-limiting enzyme in the biosynthesis of serotonin, may be a factor influencing serotonin turnover and behaviors controlled by serotonin. METHODS: Using a polymerase chain reaction-based method, TPH genotype was determined in DNA samples from 56 impulsive and 14 nonimpulsive, alcoholic, violent offenders and 20 healthy volunteers. RESULTS: In the behaviorally extreme impulsive group, we observed a significant association between TPH genotype and cerebrospinal fluid 5-hydroxyindoleacetic acid (5-HIAA) concentration. No association of TPH genotype with impulsive behavior was detected. The polymorphism was also associated with a history of suicide attempts in all violent offenders, independent of impulsivity status and cerebrospinal fluid 5-HIAA concentration. CONCLUSION: In some individuals, a genetic variant of the TPH gene may influence 5-HIAA concentration in the cerebrospinal fluid and predisposition to suicidal behavior.

The prevalence and correlates of DSM-IV intermittent explosive disorder in the National Comorbidity Survey Replication.

CONTEXT: Little is known about the epidemiology of intermittent explosive disorder (IED). OBJECTIVE: To present nationally representative data on the prevalence and correlates of DSM-IV IED. DESIGN: The World Health Organization Composite International Diagnostic Interview was used to assess DSM-IV anxiety disorders, mood disorders, substance use disorders, and impulse control disorders. SETTING: The National Comorbidity Survey Replication, a face-to-face household survey carried out in 2001-2003. PARTICIPANTS: A nationally representative sample of 9282 people 18 years and older. MAIN OUTCOME MEASURE: Diagnoses of DSM-IV IED. RESULTS: Lifetime and 12-month prevalence estimates of DSM-IV IED were 7.3% and 3.9%, with a mean 43 lifetime attacks resulting in 1359 dollars in property damage. Intermittent explosive disorder-related injuries occurred 180 times per 100 lifetime cases. Mean age at onset was 14 years. Sociodemographic correlates were uniformly weak. Intermittent explosive disorder was significantly comorbid with most DSM-IV mood, anxiety, and substance disorders. Although the majority of people with IED (60.3%) obtained professional treatment for emotional or substance problems at some time in their life, only 28.8% ever received treatment for their anger, while only 11.7% of 12-month cases received treatment for their anger in the 12 months before interview. CONCLUSIONS: Intermittent explosive disorder is a much more common condition than previously recognized. The early age at onset, significant associations with comorbid mental disorders that have later ages at onset, and low proportion of cases in treatment all make IED a promising target for early detection, outreach, and treatment.

Obsessive-compulsive spectrum conditions in obsessive-compulsive disorder and other anxiety disorders.

In light of current interest in an obsessive-compulsive spectrum of disorders, this study sought to determine whether comorbidity patterns support the unique relationship hypothesized between these conditions and obsessive-compulsive disorder (OCD). Comparisons were made of lifetime rates of several proposed spectrum conditions in individuals with one of three anxiety disorder principal diagnoses (OCD, social phobia, or panic disorder [PD], N=277). Spectrum conditions examined included tic-related disorders, trichotillomania, skin picking, and eating disorders, with analyses performed on rates both of clinical disorder alone, and clinical and subclinical manifestations jointly. The OCD group was found to differ from both other groups in showing 1) a greater proportion of individuals affected with any lifetime spectrum condition, 2) a greater number of lifetime spectrum conditions affecting each individual, and 3) a greater proportion of individuals having a lifetime history of multiple spectrum conditions. Analyses for specific spectrum conditions indicated differences among the anxiety disorder groups for all spectrum categories except eating disorders, though only in the case of tic-related conditions did OCD differ significantly from both comparison groups. For the other conditions, dissimilar patterns of differences were observed among the three groups, particularly when subclinical manifestations were included. These findings have conceptual and clinical implications, including 1) the salience of tic-related disorders in the OC spectrum, 2) the possibility that the relationship between spectrum conditions and anxiety disorders may take several different forms, and 3) the need for refinement of the hypothesized spectrum.

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.

Laxative misuse and behavioral disinhibition in bulimia nervosa.

OBJECTIVE: Various reports suggest that purging with laxatives is associated with greater behavioral impulsivity in bulimia nervosa (BN) patients. We investigated the extent to which laxative misuse corresponds to specific impulse-control problems. METHOD: Participants included bulimic women who misuse laxatives (BNL+; n = 12), bulimic women who do not misuse laxatives (BNL-; n = 33), and healthy normal eaters (NE; n = 26). Participants completed the Go/No-Go discrimination task (a well-validated computerized measure of response disinhibition), as well as self-report questionnaires of impulsivity, eating symptoms, and general psychopathology. RESULTS: Compared with the other groups, the BNL+ group made more commission errors on the Go/No-Go under cues for punishment, indicating they were more disinhibited when faced with possible negative outcomes. Compared with the BNL- group, the BNL+ group was also more likely to differ from the NE group on self-reported impulsivity. There were no differences between the two bulimic groups on eating symptoms and the three groups did not differ in terms of general psychopathology. DISCUSSION: Findings suggest that, controlling for eating symptoms and psychopathology, laxative misuse among BN patients is associated with difficulty inhibiting incorrect responses in the face of perceived threats.

Genetic analysis of bulimia nervosa: methods and sample description.

OBJECTIVE: Twin and family studies suggest that genetic variants contribute to the pathogenesis of bulimia nervosa (BN) and anorexia nervosa (AN). The Price Foundation has supported an international, multisite study of families with these disorders to identify these genetic variations. The current study presents the clinical characteristics of this sample as well as a description of the study methodology. METHOD: All probands met modified criteria for BN or bulimia nervosa with a history of AN (BAN) as defined in the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994). All affected relatives met DSM-IV criteria for BN, AN, BAN, or eating disorders not otherwise specified (EDNOS). Probands and affected relatives were assessed diagnostically using both trained-rater and self-report assessments. DNA samples were collected from probands, affected relatives, and available biologic parents. RESULTS: Assessments were obtained from 163 BN probands and 165 BAN probands. Overall, there were 365 relative pairs available for linkage analysis. Of the affected relatives of BN probands, 62 were diagnosed as BN (34.8%), 49 as BAN (27.5%), 35 as AN (19.7%), and 32 as EDNOS (18.0%). For the relatives of BAN probands, 42 were diagnosed as BN (22.5%), 67 as BAN (35.8%), 48 as AN (25.7%), and 30 as EDNOS (16.0%). DISCUSSION: This study represents the largest genetic study of eating disorders to date. Clinical data indicate that although there are a large number of individuals with BN disorders, a range of eating pathology is represented in the sample, allowing for the examination of several different phenotypes in molecular genetic analyses.

Are there subgroups of bulimia nervosa based on comorbid psychiatric disorders?

OBJECTIVE: The current study sought to determine whether there are subtypes of bulimia nervosa (BN) differentiated by comorbid psychiatric disorders. METHOD: Data on comorbid psychiatric diagnoses in female relatives of probands and controls in the Collaborative Study of the Genetics of Alcoholism (COGA) who met criteria for BN (as outlined in the 3rd Rev. ed. of the Diagnostic and Statistical Manual of Mental Disorders) were analyzed using latent class analysis. Resulting latent classes were compared on a variety of variables related to impulsive behaviors and psychological functioning. RESULTS: The best-fitting solution, a two-class model, yielded one class (72%) characterized by substance dependence, depression, antisocial personality disorder (ASPD), and anxiety disorders, and another characterized by depression. The highly comorbid class had more suicidality, more daily smokers, sought help for emotional problems, and had lower Global Assessment of Functioning (GAF) scores compared with those in the comorbid depression only class. DISCUSSION: Latent class findings suggest the existence of two classes of BN differentiated by substance dependence, impulsive behaviors, and poorer psychological functioning.

The children's firesetting interview with psychiatrically referred and nonreferred children.

This study evaluated the Children's Firesetting Interview (CFI). The measure was developed to operationalize multiple domains of functioning derived from a risk-factor model of firesetting. The model poses that child, parent, and family characteristics promote firesetting and continuation of a pattern of firesetting. Major factors include curiosity about fire, involvement in and exposure to fire-related activities, and knowledge about first safety The CFI, consisting of 46 questions reflecting six a priori dimensions, was administered to 519 children (ages 6-13) recruited from nonpatient, outpatient, and inpatient samples. Internal consistency and test-retest reliability of the measure were satisfactory. Criterion validity was supported by the findings that firesetters showed greater curiosity about fire, involvement in fire-related activities, exposure to models/materials, and knowledge about things that burn than did nonfiresetters. These findings did not vary as a function of the child's patient status or level of antisocial behavior. Implications for the evaluation of firesetting risk are discussed.

[Compulsive shopping--current considerations on classification and therapy].

Compulsive shopping is classified by ICD-10 (F63.8) as an "impulse control disorder, not otherwise classified". Several authors consider compulsive shopping rather as a variety of dependence disorder. It is characterized by the impulsive or compulsive buying of unneeded things, personal distress, impaired social and vocational functioning, and/or financial problems. In this case, we discuss a two-way therapy consisting of addiction-specific psychological education and high dose selective serotonin reuptake inhibitors (SSRIs). We further point to compliance problems caused by SSRI side effects.

Epidemiologic and clinical updates on impulse control disorders: a critical review.

The article reviews the current knowledge about the impulse control disorders (ICDs) with specific emphasis on epidemiological and pharmacological advances. In addition to the traditional ICDs present in the DSM-IV-pathological gambling, trichotillomania, kleptomania, pyromania and intermittent explosive disorder-a brief description of the new proposed ICDs-compulsive-impulsive (C-I) Internet usage disorder, C-I sexual behaviors, C-I skin picking and C-I shopping-is provided. Specifically, the article summarizes the phenomenology, epidemiology and comorbidity of the ICDs. Particular attention is paid to the relationship between ICDs and obsessive-compulsive disorder (OCD). Finally, current pharmacological options for treating ICDs are presented and discussed.
