Relationship of obsessive-compulsive symptomatology to anxiety, depression and schizotypy in a clinical population.

The relationship of obsessive-compulsive symptomatology to anxiety disorders, mood disorders and schizophrenia continues to be controversial. In a sample of 117 psychiatric out-patients, we examined the relationship of obsessive-compulsive symptomatology to indices of anxiety, depression and schizotypy. The relationship between obsessive-compulsive symptomatology and schizotypy was found to be significantly higher than that between obsessive-compulsive symptoms and either anxiety or depression. These findings are consistent with recent studies suggesting that there are similar cognitive deficits associated with obsessive-compulsive symptoms and schizotypy and that obsessive-compulsive disorders may be more closely aligned to the schizophrenic constellation of disorders than to anxiety disorders.

Psychopathological considerations on the relationship between bulimia and obsessive-compulsive disorder.

The relationship between eating disorders, impulse control disorders and obsessive-compulsive disorder as part of a so-called 'obsessive-compulsive spectrum' is discussed, with particular emphasis on the relationship between eating disorders (particularly bulimia) and obsessive-compulsive disorder. The empirical studies on comorbidity, personality and familiarity are briefly reviewed. Both similarities and differences found in personality, body image, mental rumination, fears, physical exercises, rituals, impulses (bulimic binging and obsessive impulses) and purging behaviors of these patients are discussed from a psychopathological point of view. In particular the importance of distinguishing between obsessive thoughts and prevalent (dominant) thoughts is underlined; the distinctions between repetitive weight controls, physical exercises and purging behaviors of eating disorder patients on the one hand and compulsions on the other, and the distinction between binge impulses and obsessive impulses, are also stressed.

Insight and resistance in patients with obsessive-compulsive disorder.

The aim of this study was to evaluate the degree of insight and resistance in a sample of obsessive-compulsive patients, and the predictive value of poor insight with respect to response to treatment with serotonin reuptake inhibitors (SRIs). Ninety-three patients fulfilling DSM-IV criteria for obsessive-compulsive disorder were evaluated. Seventy patients were treated with an SRI in a 24-week open-label trial. Sixteen percent of the patients did not recognize obsessions and compulsions as unreasonable or senseless. Fifty-two percent of the patients did not try to resist, 72% had little or no control over obsessions, and 64% were not able to exercise an effective control over compulsions. Patients with poor insight had a greater severity of obsessive-compulsive symptoms, a higher rate of schizophrenia spectrum disorders in their first-degree relatives and a higher frequency of a history of psychiatric disorders during childhood. Fifty-two percent of the patients with normal insight responded to SRIs, whereas none of the patients with poor insight were found to be responders. These results suggest the utility of the assessment of insight and resistance in obsessive-compulsive patients, also for the prediction of response to treatment with SRIs.

Anterior capsulotomy for treatment of refractory obsessive-compulsive disorder: results in a young and an old patient.

The objective of this case report was to assess the effect of anterior capsulotomy for obsessive-compulsive disorder (OCD) in 2 patients beyond extremes of age ranges of published radiofrequency capsulotomy. The youngest patient developed OCD at age 10 with increasing symptoms of tension and worry. The symptoms were refractory to medications and behavioral therapy. He underwent anterior capsulotomy at age 18. The older patient was 64 at the time of surgery. His OCD began about age 17 with checking and counting rituals. His obsessions extended into other areas such as fear of injuring people while driving. His work performance was greatly compromised. Despite medication trials his rituals and obsessions intensified. After 47 years of severe symptoms he underwent surgery. The youngest patient returned to high school full-time and graduated. He was able to read and comprehend without obsessing about the meaning of words. His thinking and behavior became symptom free and he married 4.5 years after surgery. His score on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) after surgery on no medication is zero. The older patient improved gradually without medication. He could play with and touch his grandchildren for the first time. He could drive a car again and his Y-BOCS dropped from 30 preoperatively to 8. Twenty-four months after surgery he is essentially free of obsessions, compulsions and anxiety. We conclude that treatment-refractory OCD may be alleviated by anterior radiofrequency capsulotomy in the young and the old patient. This study expands the documented age range of response from 18 to 64.

Chlorimipramine therapy for obsessive-compulsive neurosis.

Twenty patients with a history of treatment-resistant obsessional neurosis underwent a 4-week clinical trial of chlorimipramine. Scores on the Psychiatric Questionnaire for Obsessive Compulsive Neurosis, the Leyton Obsessional Inventory, and 3 self-assessments indicated that although there was no significant change in obsessive ruminations, obsessive rituals, horrific temptations, or pervading doubt, there was a substantial significant improvement in the obsessive symptom item and severity of obsessions, as well as anxiety, depression, and phobia. Side effects were mild. The authors believe that chlorimipramine is the most promising treatment for obsessive-compulsive neurosis.

Tics and Tourette's disorder: a 2- to 7-year follow-up of 54 obsessive-compulsive children.

OBJECTIVE: This study examined a hypothesized etiologic relationship between Tourette's disorder and obsessive-compulsive disorder. METHOD: Fifty-four children who had initially participated in treatment protocols for obsessive-compulsive disorder (Tourette's disorder was an exclusionary criterion) were reevaluated 2-7 years later with a neurological examination and a structured interview to establish the presence or absence of tics and Tourette's disorder. The children's first-degree relatives (N = 171) were also screened for tic disorders. RESULTS: At baseline, 57% (N = 31) of the patients had lifetime histories of tics. At follow-up, 59% (N = 32) had lifetime histories of tics; eight of these (all males) met the criteria for Tourette's disorder (six had developed the disorder, and two, it could be argued in retrospect, might have met the criteria at baseline). The patients with lifetime histories of tics had greater anxiety, a higher ratio of CSF 5-hydroxyindoleacetic acid to homovanillic acid, and a younger age at onset of obsessive-compulsive disorder than those without tics. The patients with Tourette's disorder differed from other male patients only in having an earlier age at onset of obsessive-compulsive disorder. Of the first-degree relatives, 1.8% (N = 3) had Tourette's disorder, and 14% (N = 24) had a tic disorder. CONCLUSIONS: Except for their earlier age at onset of obsessive-compulsive disorder, the patients with Tourette's disorder were indistinguishable from those without. The apparent high rate of tics and Tourette's disorder in the subjects and their relatives is consistent with the hypothesis that in some cases, obsessive-compulsive disorder and Tourette's disorder may be alternative manifestations of the same underlying illness.

Laboratory response of patients with panic and obsessive-compulsive disorders to 35% CO2 challenges.

OBJECTIVE: The DSM-III-R anxiety disorders section includes both panic disorder and obsessive-compulsive disorder. To evaluate the relationship between these two disorders, subject responses to inhalation of a 35% CO2 and 65% O2 mixture were assessed. METHODS: Twenty-three patients with panic disorder, 23 with obsessive-compulsive disorder, 12 with both obsessive-compulsive and panic disorder, and 23 healthy comparison subjects were given a single vital capacity inhalation of 35% CO2 and 65% O2 or a placebo mixture of compressed air. A double-blind, random, crossover design was used. RESULTS: Patients with panic disorder and patients with both panic disorder and obsessive-compulsive disorder showed similar strong anxiogenic reactions to 35% CO2; while patients with obsessive-compulsive disorder alone did not differ from comparison subjects. CONCLUSIONS: These results confirm that obsessive-compulsive disorder and panic disorder are two distinct syndromes and that patients with these disorders have different sensitivity to CO2 inhalation.

Body dysmorphic disorder in the DSM-IV field trial for obsessive-compulsive disorder.

OBJECTIVE: This study investigated the prevalence and phenomenology of body dysmorphic disorder in patients with obsessive-compulsive disorder. METHOD: The authors studied 442 patients who participated in the DSM-IV field trial for obsessive-compulsive disorder. RESULTS: Twelve percent (N = 51) of the patients had a lifetime comorbid diagnosis of body dysmorphic disorder. Patients with and without body dysmorphic disorder did not differ in demographic characteristics of obsessive-compulsive symptoms. Patients with obsessive-compulsive disorder and body dysmorphic disorder had more anxious, impulsive, and schizotypal features than patients with obsessive-compulsive disorder alone. Age at onset was similar for the two disorders, and severity correlated. However, insight was significantly more impaired for body dysmorphic disorder than for obsessive-compulsive disorder. CONCLUSIONS: As previously thought, these findings suggest that the two disorders are strongly related but also have differences that require further investigation.

Obsessive-compulsive disorder in patients with schizophrenia or schizoaffective disorder.

OBJECTIVE: The authors evaluated the frequency of DSM-III-R obsessive-compulsive disorder in patients with a primary diagnosis of schizophrenia or schizoaffective disorder. METHOD: Patients with schizophrenia (N = 52) or schizoaffective disorder (N = 25) were evaluated for the presence of obsessions and compulsions by means of the Structured Clinical Interview for DSM-III-R, the Yale-Brown Obsessive Compulsive Scale, chart review, and contact with the treating clinicians. RESULTS: Six (7.8%) of the 77 patients met the DSM-III-R criteria for both obsessive-compulsive disorder and schizophrenia or schizoaffective disorder. CONCLUSIONS: These findings suggest that obsessive-compulsive disorder occurs in a substantial percentage of patients with schizophrenia or schizoaffective disorder. The addition of medications targeted at obsessive-compulsive disorder may be beneficial to these patients but requires systematic evaluation.

Obsessive-compulsive disorder with and without tics in an epidemiological sample of adolescents.

OBJECTIVE: This study was undertaken to discriminate subtypes of obsessive-compulsive disorder in adolescents. METHOD: Forty individuals with obsessive-compulsive spectrum disorders were ascertained from an epidemiological sample of 861 adolescents. Interviews were conducted by child psychiatrists using semistructured diagnostic interviews, including a clinician-rated Yale-Brown Obsessive Compulsive Scale. Discriminant analysis was performed to compare the scores on the Yale-Brown scale of groups with and without comorbid tics and to compare boys and girls. RESULTS: Adolescents with tics were more prone to aggressive and sexual images and obsessions than were adolescents without tics; these differences could not be wholly attributed to sex differences. CONCLUSIONS: The subtypes among unreferred adolescents are similar to those of adult patients with obsessive-compulsive disorder with and without Gilles de la Tourette syndrome. Subtypes evident in adulthood may be established relatively early in the natural course of obsessive-compulsive disorder.

Obsessive-compulsive disorder in the community: an epidemiologic survey with clinical reappraisal.

OBJECTIVE: To examine the prevalence of obsessive-compulsive symptoms and DSM-IV obsessive-compulsive disorder (OCD), the authors conducted a telephone survey of 2,261 adults in four regions of Canada. METHOD: Trained lay interviewers administered a modified version of the OCD section of the Comprehensive International Diagnostic Interview. A subsample of respondents with probable cases and probable subclinical cases of OCD was then blindly reinterviewed by research personnel experienced in the assessment of OCD, using the Structured Clinical Interview for DSM-IV and the Yale-Brown Obsessive Compulsive Scale, to confirm the diagnosis and gauge the severity of OCD. RESULTS: The weighted 1-month prevalence of OCD in the entire sample according to the lay interviews was 3.1%. Upon clinical reappraisal, the 1-month prevalence estimate of OCD dropped to 0.6%; an additional 0.6% had subclinical OCD. The mean Yale-Brown Obsessive Compulsive Scale score of the individuals with OCD was 19.0 (SD = 4.6, median = 21); for those with subclinical OCD, the mean score was 15.4 (SD = 2.4, median = 14). Common reasons for overdiagnosis of OCD by the lay interviewers were inappropriate labeling of worries or concerns as obsessions and overestimating the degree of interference or distress attributable to obsessive-compulsive symptoms. CONCLUSIONS: OCD, while hardly a rare condition, may be somewhat less prevalent than had been believed on the basis of previous surveys. Additional studies are needed to substantiate these findings and to delineate precisely the extent of disability and reduced quality of life attributable to OCD (and OCD variants) in the community.

Morbidity risk for obsessive-compulsive spectrum disorders in first-degree relatives of patients with eating disorders.

OBJECTIVE: A hypothesis that eating disorders are a phenomenological variant of obsessive-compulsive disorder (OCD) has been proposed. This study was conducted to determine whether anorexia nervosa and bulimia, the two main eating disorders, are familial and whether the risk for obsessive-compulsive spectrum disorders (OCD and tic disorders) is higher in families of patients with eating disorders. METHOD: The morbidity risk for obsessive-compulsive spectrum disorders in first-degree relatives of 136 female probands with eating disorders (84 with anorexia nervosa, 52 with bulimia) was compared to that for first-degree relatives of 72 female comparison subjects. RESULTS: The morbidity risk for obsessive-compulsive spectrum disorders was significantly higher among the 436 relatives of the eating disorder probands than among the 358 relatives of the comparison subjects (9.69% versus 0%). This finding was independent of any comorbid diagnosis of an obsessive-compulsive spectrum disorder in the eating disorder probands. The eating disorder group and the comparison group did not differ in familial risk for eating disorders and tic disorders. CONCLUSIONS: To better understand the genetic components of eating disorders, these disorders should be considered as part of the obsessive-compulsive spectrum of disorders.

Childhood obsessive-compulsive personality traits in adult women with eating disorders: defining a broader eating disorder phenotype.

OBJECTIVE: The authors retrospectively examined a spectrum of childhood traits that reflect obsessive-compulsive personality in adult women with eating disorders and assessed the predictive value of the traits for the development of eating disorders. METHOD: In a case-control design, 44 women with anorexia nervosa, 28 women with bulimia nervosa, and 28 healthy female comparison subjects were assessed with an interview instrument that asked them to recall whether they had experienced various types of childhood behavior suggesting traits associated with obsessive-compulsive personality. The subjects also completed a self-report inventory of obsessive-compulsive disorder (OCD) symptoms. RESULTS: Childhood obsessive-compulsive personality traits showed a high predictive value for development of eating disorders, with the estimated odds ratio for eating disorders increasing by a factor of 6.9 for every additional trait present. Subjects with eating disorders who reported perfectionism and rigidity in childhood had significantly higher rates of obsessive-compulsive personality disorder and OCD comorbidity later in life, compared with eating disorder subjects who did not report those traits. CONCLUSIONS: Childhood traits reflecting obsessive-compulsive personality appear to be important risk factors for the development of eating disorders and may represent markers of a broader phenotype for a specific subgroup of patients with anorexia nervosa.

A review of pharmacologic treatments for obsessive-compulsive disorder.

OBJECTIVE: Obsessive-compulsive disorder is a chronic and often disabling disorder that affects 2 to 3 percent of the U.S. population. Optimal treatment involves a combination of pharmacologic and cognitive-behavioral therapies. Advances in psychopharmacology have led to safe and effective treatments for obsessive-compulsive disorder that provide clinically significant improvement in symptoms. In this article the authors review studies of pharmacologic treatments. METHODS: A MEDLINE search was conducted to identify relevant articles from 1991 to 2002. Double-blind, placebo-controlled studies as well as open-label studies and case reports were included. RESULTS AND DISCUSSION: The serotonin reuptake inhibitors (SRIs), including clomipramine, fluvoxamine, fluoxetine, sertraline, and paroxetine, have been approved by the U.S. Food and Drug Administration for the treatment of adults with obsessive-compulsive disorder; three of these (clomipramine, fluvoxamine, and sertraline) have been approved for treatment of children and adolescents. Clomipramine and the selective serotonin reuptake inhibitors (SSRIs) are first-line agents. However, 40 to 60 percent of patients with obsessive-compulsive disorder do not respond to adequate treatment trials with SRIs, and agents that alter serotonin receptors and other neurotransmitter systems, such as dopamine, norepinephrine, and second-messenger systems, may play a role in treatment. Treatment options for patients who do not respond to SRIs include switching, augmentation, or novel-agent strategies. Up to two-thirds of patients with obsessive-compulsive disorder have comorbid psychiatric disorders, which may present a challenge in pharmacologic treatment. Major depressive disorder is the most common comorbid condition. Nonpharmacologic invasive techniques may play a role in refractory cases of obsessive-compulsive disorder, but further research is warranted.

Increased medial thalamic creatine-phosphocreatine found by proton magnetic resonance spectroscopy in children with obsessive-compulsive disorder versus major depression and healthy controls.

Altered brain creatine-phosphocreatine levels might reflect changes in brain energy use and have been implicated in the pathogenesis of obsessive-compulsive disorder and major depressive disorder. We used proton magnetic resonance spectroscopy to measure absolute concentrations of creatine-phosphocreatine in the right and left medial thalami in 18 pediatric patients with major depressive disorder 9 to 17 years of age, 18 case-matched healthy controls, and 27 patients with obsessive-compulsive disorder 7 to 16 years old. The two patient groups were psychotropic drug naive and were not comorbid for the diagnosis of the comparison group. We found significantly increased left and right medial thalamic creatine-phosphocreatine concentrations in patients with obsessive-compulsive disorder compared with both healthy controls and patients with major depression. Creatine-phosphocreatine concentrations did not differ significantly between patients with major depression and healthy controls. Our data suggest that increased medial thalamic creatine-phosphocreatine concentrations in patients with untreated obsessive-compulsive disorder reflect altered energy use in the medial thalamus and might differentiate patients with obsessive-compulsive disorder from healthy controls and patients with major depression. Although these results must be considered preliminary, further study of the diagnostic specificity of creatine-phosphocreatine in obsessive-compulsive disorder is indicated.

A phenomenological analysis of symptoms in obsessive-compulsive neurosis.

Eighty-two obsessional neurotics were studied from a phenomenological point of view in order to delineate the various forms and contents of obsessions and compulsions. An attempt was made to ascertain the frequency with which the different forms and content occur and their effect on the final outcome of the disorder. Five types of obsessions were identified: doubts, obsessive thinking, fears, impulses, and images, in order of frequency of their occurrence. Compulsive acts could be classified in two types, depending on whether they yielded to or diverted the underlying obsession. One-fourth of the patients displayed no compulsions. The content of obsession could be classified in five broad categories as relating to: dirt and contamination, aggression, inanimate-impersonal themes, religion, and sexual matters, in order of the frequency of their occurrence. The paper, while offering an interpretation of these findings, emphasizes the part played by socio-cultural factors in the character of an obsession's thought content. The absence of compulsions was found to be associated with good prognosis. A downward gradient was noted in the final outcome of patients without compulsions, those with controlling compulsions alone, those with both varieties of compulsions, and those displaying yielding compulsions alone, in that order. Based on this observation the paper suggests a prognosis-related hierarchical continuum of the severity of obsessional disorder.

A dialogical approach to obsessions.

Cognitive conceptualizations of obsessions based on the information-processing metaphor are contrasted with a dialogical approach to understanding obsessive compulsive disorder (OCD). The dialogical approach views obsessions as one-sided conversations. The unit of analysis is the narrative or 'voice', which engages the person in the neutralizing behaviour. The dialogical approach accommodates well the apparent paradox that obsessions are both self and other generated, and that people can be positioned differently regarding the senselessness of their obsessions at different times. Also, people themselves characterize their obsessions in dialogical terms as: voice, conversation, or argument. The focus of therapy is the language and power of the narrative rather than discrete cognitive biases or representations, and dialogical therapy emphasizes role-play and narrative techniques. Cognitive therapy has already shown signs of adopting a narrative turn, and cognitive and dialogical conceptualizations of OCD are alternative perspectives rather than competing explanations.

Effectiveness of paroxetine in the treatment of obsessive-compulsive disorders.

Clomipramine ushered in a new age of pharmacotherapy for obsessive-compulsive disorders, and it also facilitated our understanding of the biological aspects of obsessive-compulsive disorder, focusing on the serotonergic systems. The introduction of selective serotonin reuptake inhibitors has led to great progress in the pharmacological study of obsessive-compulsive disorder based on the serotonin hypothesis. Currently, selective serotonin reuptake inhibitors are positioned as a first-line drug of obsessive-compulsive disorder pharmacotherapy in the various guidelines and algorithms. Among six different selective serotonin reuptake inhibitors (paroxetine, sertraline, fluoxetine, fluvoxamine, citalopram, escitalopram) that are available worldwide, paroxetine has the broadest treatment spectrum and promises great benefits not only for obsessive-compulsive disorder patients, but also for those with comorbid depression and/or various kinds of anxiety disorders. This paper presents several clinical trials of paroxetine carried out, and discusses and reviews the therapeutic strategies for obsessive-compulsive disorder.
