Symptom presentation and outcome of cognitive-behavioral therapy for obsessive-compulsive disorder.

Previous researchers have classified obsessive-compulsive disorder (OCD) patients by the themes of their obsessions and compulsions (e.g., washing, checking); however, mental compulsions have not been adequately assessed in these studies. The authors conducted 2 studies using a large sample of OCD patients (N=132). In the 1st study, they categorized patients on the basis of symptom presentation, giving adequate consideration to mental compulsions. Five patient clusters were identified: harming, contamination, hoarding, unacceptable thoughts, and symmetry. Mental compulsions were most prevalent among patients with intrusive, upsetting religious, violent, or sexual thoughts. In the 2nd study, they compared response to cognitive-behavioral therapy across symptom categories, finding poorer outcomes among patients with hoarding symptoms compared with those with other symptom themes.

Les passions de l'ame: on obsessive and harmonious passion.

Passion is defined as a strong inclination toward an activity that people like, that they find important, and in which they invest time and energy. Two types of passion are proposed: obsessive and harmonious. Obsessive passion (OP) refers to a controlled internalization of an activity in one's identity that creates an internal pressure to engage in the activity that the person likes. Harmonious passion (HP) refers to an autonomous internalization that leads individuals to choose to engage in the activity that they like. HP promotes healthy adaptation whereas OP thwarts it by causing negative affect and rigid persistence. Results from four studies involving more than 900 participants from different populations supported the proposed conceptualization.

Deficits of organizational strategy and visual memory in obsessive-compulsive disorder.

This study was conducted to investigate the deficits of organizational strategy and visual memory in obsessive-compulsive disorder (OCD). Thirty OCD patients and 30 healthy controls aged 20-35 years participated. The Maudsley Obsessive-Compulsive Inventory, Beck Anxiety Inventory, Wechsler Adult Intelligence Scale, and Rey-Osterrieth Complex Figure (ROCF) test were administered to participants. The authors scored ROCF performances using the Boston Qualitative Scoring System. The OCD patients showed poorer planning ability and higher fragmentation than did healthy controls when copying the ROCF, and they showed even poorer performances in the immediate and delayed recall conditions. The authors found that the Organization score in the copy condition mediated the difference between the OCD group and the healthy group in immediate recall. The direct effect of diagnosis (OCD or healthy) on the immediate recall condition of the ROCF was also significant. This study indicates that people with OCD have poor memory function and organizational deficits.

Evidence for linkage disequilibrium between serotonin transporter protein gene (SLC6A4) and obsessive compulsive disorder.

Obsessive compulsive disorder (OCD) is characterized by recurrent and intrusive thoughts that are distressing (obsessions) and/or repetitive behaviors or mental acts that the person feels driven to perform (compulsions). OCD has a partly genetic basis. For treatment of OCD, potent serotonin reuptake inhibitor (SRI) drugs (clomipramine (Anafranil), fluvoxamine (Luvox), fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil)), which act on the serotonin transporter protein, are uniquely efficacious. A polymorphism in the promoter region of the gene (SLC6A4) encoding this protein, was recently reported to affect protein expression and to be associated with measures of anxiety and depression and with autism (using a family-controlled transmission disequilibrium test (TDT) design). SLC6A4 therefore has strong a priori support for potentially influencing risk for OCD: the protein it encodes is a medication target; a polymorphism in the gene affects function; and that polymorphism has been shown to be associated with behavioral phenotypes. We used the TDT with a set of 34 European-American family trios, 30 unrelated and four drawn from an extended pedigree, to test for linkage disequilibrium between OCD and alleles at the SLC6A4 promoter polymorphic locus. Of 35 heterozygous parents, 24 transmitted the 'l' SLC6A4 allele and 11 transmitted the 's' allele (chi 2 TDT = 4.83; P < 0.03). Considering only the 13 SRI drug nonresponders, there were 13 heterozygous parents, of whom 10 transmitted the 'l' allele and three the 's' allele (chi 2 TDT = 3.77; P < 0.052). These data provide preliminary support for association and linkage disequilibrium between the SLC6A4 'l' allele and OCD.

A transgenic model of comorbid Tourette's syndrome and obsessive-compulsive disorder circuitry.

The tic disorder Tourette's Syndrome (TS) and obsessive-compulsive disorder (OCD) are comorbid behavioral disorders, suggesting a shared but still unknown neuronal basis. To 'circuit-test' such behaviors, we previously engineered transgenic mice expressing a neuropotentiating protein (cholera toxin A1 subunit) within a cortical-limbic subset of dopamine D1-receptor expressing (D1+) neurons known to trigger glutamatergic excitation of orbitofrontal, sensorimotor, limbic and efferent striatal circuits thought to be hyperactive or affected in OCD and TS. These mice exhibited OCD-like behaviors including generalized behavioral perseveration and compulsion-like leaping and grooming-associated pulling and biting of skin and hair. We now report that these OCD-like mice, like humans, also exhibit comorbid TS-like behaviors, including juvenile-onset tics; increased tic number, complexity and flurries; increased tic severity in males; voluntary tic suppression; and tic responsiveness to a non-cataleptic TS+OCD drug therapy (clonidine, 0.01 mg kg(-1)). These data suggest that hormonal gender differences, apart from the influence of genetic or autoimmune etiologic factors, may be sufficient to aggravate tic severity in human TS males compared to TS females. These data also proffer a precise neuronal basis for TS+OCD, wherein tics and primary compulsions or obsessions are evoked by hyperactivity of various cortical-limbic projection neurons' glutamatergic output to efferent targets like the striatum. The 'Cortical-limbic Glutamatergic Neuron' (CGN) neuronal circuit model merges formerly opposed neurotransmitter models of TS and OCD, and is consistent with new clinical reports of increased cortical hyperactivity, striatal glutamate and striatal inhibitory D2 receptors, and reduced striatal responsiveness, in these disorders.

Selective alleviation of compulsive lever-pressing in rats by D1, but not D2, blockade: possible implications for the involvement of D1 receptors in obsessive-compulsive disorder.

Rats undergoing extinction of lever-pressing for food after the attenuation of an external feedback for this behavior exhibit excessive lever-pressing unaccompanied by an attempt to collect a reward. This behavior may be analogous to the excessive and unreasonable behavior seen in obsessive-compulsive disorder. In the present study, we tested the hypothesis that the compulsive behavior induced by signal attenuation is mediated via D(1) rather than D(2) receptors. Administration of 0.005, 0.01 and 0.03 mg/kg of the D(1) antagonist SCH 23390 reduced the number of compulsive lever-presses without affecting the number of lever-presses followed by an attempt to collect a reward. In contrast, administration of 0.005, 0.01, 0.024, 0.036 and 0.05 of the D(2) antagonist haloperidol dose-dependently decreased both types of lever-presses. In addition, haloperidol at doses that decreased lever-pressing in the post-training signal attenuation procedure (0.036 and 0.05 mg/kg) had a similar effect in regular extinction, whereas an SCH 23390 dose that decreased compulsive lever-pressing in the post-training signal attenuation procedure (0.01 mg/kg) had no effect on regular extinction. On the basis of electrophysiological data on the response of dopamine neurons to the omission of an expected reward, these results were interpreted as suggesting that compulsive lever-pressing depends on a phasic decrease in the stimulation of D(1) receptors. The implications of these results for the pathophysiology and treatment of obsessive-compulsive disorder are discussed.

Three-year outcomes in deep brain stimulation for highly resistant obsessive-compulsive disorder.

Deep brain stimulation (DBS) of the anterior limb of the internal capsule has been shown to be beneficial in the short term for obsessive-compulsive disorder (OCD) patients who exhaust conventional therapies. Nuttin et al, who published the first DBS for OCD series, found promising results using a capsule target immediately rostral to the anterior commissure extending into adjacent ventral capsule/ventral striatum (VC/VS). Published long-term outcome data are limited to four patients. In this collaborative study, 10 adult OCD patients meeting stringent criteria for severity and treatment resistance had quadripolar stimulating leads implanted bilaterally in the VC/VS. DBS was activated openly 3 weeks later. Eight patients have been followed for at least 36 months. Group Yale-Brown Obsessive Compulsive Scale (YBOCS) scores decreased from 34.6+/-0.6 (mean+/-SEM) at baseline (severe) to 22.3+/-2.1 (moderate) at 36 months (p < 0.001). Four of eight patients had a > or =35% decrease in YBOCS severity at 36 months; in two patients, scores declined between 25 and 35%. Global Assessment of Functioning scores improved from 36.6+/-1.5 at baseline to 53.8+/-2.5 at 36 months (p < 0.001). Depression and anxiety also improved, as did self-care, independent living, and work, school, and social functioning. Surgical adverse effects included an asymptomatic hemorrhage, a single seizure, and a superficial infection. Psychiatric adverse effects included transient hypomanic symptoms, and worsened depression and OCD when DBS was interrupted by stimulator battery depletion. This open study found promising long-term effects of DBS in highly treatment-resistant OCD.

Obsessive-Compulsive Disorder, 5-HTTLPR polymorphism and treatment response.

Recently, a role for a functional polymorphism within the promoter region of the serotonin transporter gene (5-HTTLPR) in conferring susceptibility to Obsessive Compulsive Disorder (OCD) has been suggested. The aim of this study was to test the hypothesis that allelic variation of the 5-HTTLPR could be associated with OCD susceptibility or influence the drug response in OCD. One hundred and eighty-one OCD patients were recruited; 92 patients underwent a standardized treatment with fluvoxamine. No significant differences in allele/genotype distribution of the 5-HTTLPR were found between 191 controls and OCD. No differences in fluvoxamine response in the three genotypes groups in OCD were found, considering Yale-Brown Obsessive Compulsive Scale (YBOCS) total scores. Nevertheless, a significant time per genotype interaction was found for the YBOCS subtotal compulsion scores. Considering patients without tic disorder co-diagnosis, a significant time per genotype interaction for both YBOCS total scores and compulsion scores was found.

Obsession of hearing music: from the viewpoint of Morita theory.

We present two typical cases among five Japanese students who have complained of hearing music. They were found among 638 student case reports during 4 years at the mental health service center of a preparatory school. We diagnosed the complaint of hearing music as a symptom of obsession. Morita therapy was an effective treatment for this symptom. We discuss the characteristics of the symptom as an obsession and the therapy in the light of Morita theory.

Validation study of the Japanese version of the Obsessive-Compulsive Drinking Scale.

The Obsessive-Compulsive Drinking Scale (OCDS) is a self-rating questionnaire that measures cognitive and behavioral aspects of craving for alcohol. The OCDS consists of two subscales: the obsessive thoughts of drinking subscale (OS) and the compulsive drinking subscale (CS). This study aims to validate the Japanese version of the OCDS. First, internal consistency and discriminant validity were evaluated. Second, a prospective longitudinal 3-month outcome study of 67 patients with alcohol dependence who participated in a relapse prevention program was designed to assess the concurrent and predictive validity of the OCDS. The OCDS demonstrated high internal consistency. The OS had high discriminant validity, while the CS did not. Twenty-three patients (34.3%) dropped out of treatment. These patients had significantly higher OS scores than those who completed the program. At 3 months, the relapse group had significantly higher OCDS scores than the no relapse group. Also, the OCDS score was higher in subjects who had early-onset alcohol dependence than late-onset dependence. The OCDS is useful for evaluating cognitive aspect of craving and predicts dropout and relapse.

Clinical features in two cases with musical obsessions who successfully responded to clomipramine.

Clinical features in two cases with musical obsessions are presented to discuss phenomenological and psychopharmacological differences from those in patients with musical hallucinations. The present patients commonly experienced music as an internally generated cognitive product accompanied by full insight into the senselessness of the symptoms. They also attempted to suppress the musical symptoms or to neutralize them with other thoughts. Thus, despite no covert or systematic compulsive behaviors, the musical symptoms of the present cases are consistent with the phenomenological nature of obsessive-compulsive disorder defined in DSM-IV. In addition, in contrast to previous case reports of musical hallucinations, the present patients failed to respond to neuroleptics, but showed significant response to an adequate trial of clomipramine. Thus, their symptoms appear to be phenomenologically and biologically distinct from musical hallucinations, especially those characteristic of schizophrenia.

Features of obsessive-compulsive disorder in patients primarily diagnosed with schizophrenia.

We investigated the prevalence of obsessive-compulsive disorder (OCD) among patients who were primarily diagnosed with schizophrenia. We investigated the differences in the neuropsychiatric features and motor symptoms between patients with schizophrenia who did or did not have OCD. Seventy-one subjects with the DSM-IV diagnosis of schizophrenia were evaluated by the Structured Clinical Interview for DSM-IV Axis I Disorders, the Yale-Brown Obsessive-compulsive Scale and the Positive and Negative Syndrome Scale. To assess their motor symptoms, the Abnormal Involuntary Movements Scale, the Barnes rating scale for drug-induced akathisia and the Simpson and Angus extrapyramidal symptoms (EPS) rating scale were used. The 13 subjects with OCD (18.3%) had significantly more severe motor symptoms than the non-OCD subjects. Patients with schizophrenia who exhibit moderate to severe motor symptoms as side-effects of neuroleptics, should be examined for OCD comorbidity. Patients who are found to have OCD comorbidity must be treated with carefully chosen medications, including serotonin re-uptake inhibitors.

Citalopram treatment of children and adolescents with obsessive-compulsive disorder: a preliminary report.

The purpose of the present study was to assess the efficacy and tolerability of citalopram in the acute treatment of children and adolescents with obsessive compulsive disorder (OCD) during an 8-week, open-label study. Fifteen patients (six female, nine male) with a mean age of 12.1 +/- 3.3 years (range: 6-17 years) were treated with citalopram (range of dose: 20-30 mg/day, mean dose: 24 +/- 5.5 mg/day). The children's version of the Yale-Brown Obsessive-Compulsive scale (CY-BOCS) was rated at the baseline, at the 4th week and at the 8th week of treatment. Fourteen patients had a decrease in total score of CY-BOCS from baseline to the 4th week of treatment (P < 0.01) and the 8th week of treatment (P < 0.01). Sedation (n = 1) and insomnia (n = 1) were reported in the first weeks of treatment. The primary data suggest the efficacy and tolerability of citalopram in young patients with OCD.

Insight and treatment outcome in obsessive-compulsive disorder.

To determine whether (1) insight in obsessive-compulsive disorder (OCD) improves when OCD symptoms improve, and whether (2) degree of insight in OCD predicts response to sertraline, data were obtained from five sites participating in a larger multisite study of relapse in OCD. During the first 16 weeks of the study, 71 patients received open-label treatment with sertraline and were assessed using the Yale-Brown Obsessive-Compulsive Rating Scale (Y-BOCS) and a rating scale to evaluate insight, the Brown Assessment of Beliefs Scale (BABS), at study baseline and termination. Baseline total BABS score was not significantly correlated with change in Y-BOCS score. Change in BABS total score and change in Y-BOCS total score were significantly correlated. There was no significant difference in mean endpoint Y-BOCS scores for patients with poor insight (n = 14) compared to patients with good insight at baseline (n = 57). Thus, insight improved with decrease in OCD symptom severity. Degree of insight at baseline did not predict response to sertraline, i.e., patients with poor insight were just as likely to respond to sertraline as patients with good insight.

Measuring social anxiety and obsessive-compulsive spectra: comparison of interviews and self-report instruments.

The present report analyzes the agreement between the interview and the self-report formats of the instruments Structured Clinical Interview for Social Anxiety Spectrum (SCI-SHY) and Structured Clinical Interview for Obsessive Compulsive Spectrum (SCI-OBS), already validated, in three psychiatric patient samples and controls. Thirty patients (10 with obsessive-compulsive disorder [OCD], 10 with social anxiety disorder [SAD], 10 with recurrent unipolar depression in remission) and 20 control subjects (10 university students, 10 ophthalmologic patients) were assessed using the SCI-SHY, the SCI-OBS, and the self report version of the two instruments. Agreement between the two versions was very good for the seven SCI-OBS domains (with intraclass correlation coefficients [ICCs] ranging from 0.80 to 0.96) and the four SCI-SHY domains (ICCs from 0.74 to 0.90). When items were analyzed individually, subjects tended to under-report some phobia-related problems in the interview. The total number of items endorsed in the SCI-SHY, but not in the SCI-OBS, was affected by the order of administration: when the SCI-SHY interview was administered first, subjects reported a median of five more symptoms; when the self-report was administered first, there was no significant difference in the number of symptoms endorsed in the two formats. However, this difference is not clinically important, given the large number of items comprising the instruments, and might be explained by the fact that subjects are likely to overemphasize occasional symptoms or behaviors when they are asked by the interviewer to answer a long series of "new" questions as accurately as possible. Given the high agreement between domain scores in the two formats of the instruments and the fact that scores are virtually identical when the self-report is administered first, we recommend the use of the self-report versions in clinical and research settings.

Obsessive-compulsive disorder with poor insight.

Although a diagnosis of obsessive-compulsive disorder (OCD) can be made with the specification "poor insight" (PI), this subtype remains understudied. To investigate the subtype, 78 OCD patients were characterized by degree of insight, reevaluated after treatment, and compared with 20 schizophrenics with OCD (OCD+S). At the pretreatment assessments in OCD patients, 28 subjects with poor or delusional insight (PI; 36%) were distinguished from 50 subjects with fair or good insight (GI; 64%) using the insight question of the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Compared to the OCD+S group, OCD patients were less likely to have PI, whereas OCD PI patients showed a similar degree of functional impairment as that observed in the OCD+S. After a 6-month combination of clomipramine with cognitive-behavioral treatment, 14 of 25 OCD PI patients no longer fell in the PI category, which was associated with reduced OCD severity and depressive status. Schizotypal personality disorder (SPD) was more common in patients whose insight remained poor even after the treatment. OCD patients demonstrate a range of insight with PI accompanied by significant dysfunction. Comorbid SPD in PI patients may be associated with worse prognosis.

Obsessive compulsive disorder: is there an association with childhood streptococcal infections and altered immune function?

During the last few years, an increased interest in the possibility of immune mediated pathophysiology of obsessive compulsive disorder (OCD) and related disorders has been seen. In the late 1980s, the National Institute of Mental Health reported an increase of obsessive compulsive symptoms in patients with Sydenham chorea (SC). Subsequently, a precipitating streptococcal infection in children with sudden onset of OCD symptoms but no chorea led to the coining of PANDAS (pediatric autoimmune neuropsychiatric disorders associated with streptococcus). This association has furthered interest in studying immune parameters in non-PANDAS OCD as well. This article will review the neuropsychiatric findings in OCD and Tourette syndrome (TS) with emphasis placed on PANDAS, and its association with SC, and a review of the existing studies that have assessed immunologic measures in patients with OCD and TS.

Serotonin and dopamine antagonism in obsessive-compulsive disorder: effect of atypical antipsychotic drugs.

BACKGROUND: Previous reports suggest that some atypical antipsychotics may have obsessogenic as well as antiobsessional effects. Given their higher affinity for serotonin 5HT2 receptors than dopamine D2 receptors, it has been speculated that atypical antipsychotics may induce obsessive-compulsive (OC) symptoms, even at low doses, due to high 5HT2 antagonism, whereas improvement in OC symptoms is thought to occur only at high doses due to high D2 antagonism. METHOD: In this open case series, the dose-response relationship of atypical antipsychotic augmentation in the treatment of obsessive compulsive disorder (OCD), and the dose-severity relationship in atypical anti psychotic-induced OC symptoms were examined. Three patients were identified who had either refractory OCD or OC symptoms following administration of atypical antipsychotics such as olanzapine and risperidone. RESULTS: Case 1: A linear dose-response relationship between increasing doses of olanzapine and improvement in OC symptoms was observed in an OCD patient resistant to 5-HT reuptake inhibitors. 2: OC symptoms induced by low doses of risperidone (1 mg) were reversed by increasing the doses of risperidone (3 mg) in a bipolar disorder patient suggesting an inverse dose-severity relationship. 3: No inverse dose-severity relationship was noted between olanzapine induced OC symptoms and its dosage in an asymptomatic OCD patient. Tretment-emergence OC symptoms responded to increasing the doses of maintanance clomipramine treatment. CONCLUSIONS: Controlled studies are needed to investigate the dose-response or dose-severity relationships between OCD and atypical antipsychotics.
