    Obsessive-compulsive disorder (OCD) is a chronic mental illness that can have a debilitating effect on daily functioning. A body of research reveals altered sleep behaviour in OCD sufferers; however, findings are inconsistent and there is no consensus on the nature of this relationship. Understanding sleep disturbance in OCD is of critical importance given the known negative consequences of disturbed sleep for mood and emotional wellbeing. A systematic literature search was conducted of five databases for studies assessing sleep in adults diagnosed with OCD. Fourteen studies met inclusion criteria and qualitative data analysis methods were used to identify common themes. There was some evidence of reduced total sleep time and sleep efficiency in OCD patients. Many of the sleep disturbances noted were characteristic of depression. However, some OCD sufferers displayed delayed sleep onset and offset and an increased prevalence of delayed sleep phase disorder (DSPD). Severe OCD symptoms were consistently associated with greater sleep disturbance. While the sleep of OCD patients has not been a major focus to date, the existing literature suggests that addressing sleep disturbance in OCD patients may ensure a holistic approach to treatment, enhance treatment efficacy, mitigate relapse and protect against the onset of co-morbid psychiatric illnesses.

    Comorbid obsessive-compulsive personality disorder (OCPD) is well-described in obsessive-compulsive disorder (OCD). It remains unclear, however, whether OCPD in OCD represents a distinct subtype of OCD or whether it is simply a marker of severity in OCD. The aim of this study was to compare a large sample of OCD subjects (n=403) with and without OCPD on a range of demographic, clinical and genetic characteristics to evaluate whether comorbid OCPD in OCD represents a distinct subtype of OCD, or is a marker of severity. Our findings suggest that OCD with and without OCPD are similar in terms of gender distribution and age at onset of OC symptoms. Compared to OCD-OCPD (n=267, 66%), those with OCD+OCPD (n=136, 34%) are more likely to present with the OC symptom dimensions which reflect the diagnostic criteria for OCPD (e.g., hoarding), and have significantly greater OCD severity, comorbidity, functional impairment, and poorer insight. Furthermore there are no differences in distribution of gene variants, or response to treatment in the two groups. The majority of our findings suggest that in OCD, patients with OCPD do not have a highly distinctive phenomenological or genetic profile, but rather that OCPD represents a marker of severity.

    Objective: The aim of this study was to identify any potential genetic overlap between attention deficit hyperactivity disorder (ADHD) and obsessive compulsive disorder (OCD). We hypothesized that since these disorders share a sub-phenotype, they may share common risk alleles. In this manuscript, we report the overlap found between these two disorders. Methods: A meta-analysis was conducted between ADHD and OCD, and polygenic risk scores (PRS) were calculated for both disorders. In addition, ...

    Posttraumatic obsessions have been reported in a few studies and case series. However, as the patients described were chronic, and the onset of their posttraumatic stress disorder (PTSD) and obsessive-compulsive disorder (OCD) symptoms was dated some time previously, this hampers interpretation of the temporal, biological and psychological relationship of OCD following traumatic events. In the current paper we describe the emergence of posttraumatic obsessions a short time following the exposure to a traumatic event. The emergence of posttraumatic obsessions, a few months after exposure to trauma, is described for five veterans. All the veterans participated in combat during the summer of 2006 (in the Second Lebanon War). For all cases, OCD symptoms were initially related to the trauma but later became generalized and independent. The course of the symptoms suggests a potential environmental role in the development of OCD following an exposure to a traumatic event. These observations suggest a biological linkage between exposure to trauma and OCD.

    Prior research has shown that youth with co-occurring tic disorders and obsessive-compulsive disorder (OCD) may differ from those with non-tic-related OCD in terms of clinical characteristics and treatment responsiveness. A broad definition of "tic-related" was used to examine whether children with tics in the Pediatric OCD Treatment Study II differed from those without tics in terms of demographic and phenomenological characteristics and acute treatment outcomes. Participants were 124 youth aged 7 to 17 years, inclusive, with a primary diagnosis of OCD who were partial responders to an adequate serotonin reuptake inhibitor (SRI) trial. Participants were randomized to medication management, medication management plus instructions in cognitive-behavioral therapy (CBT), or medication management plus full CBT. Tic status was based on the presence of motor and/or vocal tics on the Yale Global Tic Severity Scale. Tics were identified in 53% of the sample. Those with tic-related OCD did not differ from those with non-tic-related OCD in terms of age, family history of tics, OCD severity, OCD-related impairment, or comorbidity. Those with tics responded equally in all treatment conditions. Tic-related OCD was very prevalent using a broad definition of tic status. Results suggest that youth with this broad definition of tic-related OCD do not have increased OCD severity or inference, higher comorbidity rates or severity, or worsened functioning, and support the use of CBT in this population. This highlights the importance of not making broad assumptions about OCD symptoms most likely to occur in an individual with comorbid tics.

  8. Childhood-onset obsessive-compulsive disorder: a tic-related subtype of OCD?

    Eichstedt, J A; Arnold, S L

    2001-02-01

    Obsessive-compulsive disorder (OCD) is a psychiatric condition characterized by recurrent obsessions or compulsions that cause significant impairment or distress. Although OCD was once perceived to be relatively rare in childhood, current estimates suggest that as many as half of all adult OCD cases may have their onset in childhood or adolescence. In general, there appears to be a great deal of continuity between the clinical presentation of OCD in children and that in adults. Yet, numerous differences have also been found between child and adult OCD, including differences in sex distribution, patterns of comorbidity, and degree of familial loading. These differences raise the issue of whether obsessive-compulsive symptoms that have their onset in childhood, but perhaps persist into adult life, are meaningfully different from those that emerge de novo in adulthood. In this article, current research on child- and adult-onset OCD is critically reviewed. It is proposed that child-onset OCD represents a phenomenologically and etiologically distinct subtype of OCD, bearing a close genetic relationship to tic-disorders and possibly sharing a common or similar pathogenesis. Clinical implications of the child- versus adult-onset OCD distinction are discussed.

    Objective The error-related negativity (ERN) is a negative deflection in the event-related potential following an incorrect response, which is often increased in patients with obsessive-compulsive disorder (OCD). However, the relationship of the ERN to comorbid tic disorders has not been examined in patients with OCD. This study compared ERN amplitudes in patients with tic-related OCD, patients with non-tic-related OCD, and healthy controls. Method The ERN, correct response negativity, and error number were measured during an Eriksen flanker task to assess performance monitoring in 44 youth with a lifetime diagnosis of OCD and 44 matched healthy controls ranging in age from 10 to 19 years. Nine youth with OCD had a lifetime history of tics. Results ERN amplitudewas significantly increased in OCD patients compared to healthy controls. ERN amplitude was significantly larger in patients with non-tic-related OCD than either patients with tic-related OCD or controls. ERN amplitude had a significant negative correlation with age in healthy controls but not patients with OCD. Instead, in patients with non-tic-related OCD, ERN amplitude had a significant positive correlation with age at onset of OCD symptoms. ERN amplitude in patients was unrelated to OCD symptom severity, current diagnostic status, or treatment effects. Conclusions The results provide further evidence of increased error-related brain activity in pediatric OCD. The difference in the ERN between patients with tic-related and non-tic-related OCD provides preliminary evidence of a neurobiological difference between these two OCD subtypes. The results indicate the ERN is a trait-like measure that may serve as a biomarker for non-tic-related OCD. PMID:22917203

    To collate data from multiple obsessive-compulsive disorder (OCD) treatment centers across seven countries and five continents, and to report findings in relation to OCD comorbidity, age of onset of OCD and comorbid disorders, and suicidality, in a large clinical and ethnically diverse sample, with the aim of investigating cultural variation and the utility of the psychiatric diagnostic classification of obsessive-compulsive and related disorders. Researchers in the field of OCD were invited to contribute summary statistics on current and lifetime psychiatric comorbidity, age of onset of OCD and comorbid disorders and suicidality in their patients with OCD. Data from 3711 adult patients with primary OCD came from Brazil (n=955), India (n=802), Italy (n=750), South Africa (n=565), Japan (n=322), Australia (n=219), and Spain (n=98). The most common current comorbid disorders were major depressive disorder (28.4%; n=1055), obsessive-compulsive personality disorder (24.5%, n=478), generalized anxiety disorder (19.3%, n=716), specific phobia (19.2%, n=714) and social phobia (18.5%, n=686). Major depression was also the most commonly co-occurring lifetime diagnosis, with a rate of 50.5% (n=1874). OCD generally had an age of onset in late adolescence (mean=17.9years, SD=1.9). Social phobia, specific phobia and body dysmorphic disorder also had an early age of onset. Co-occurring major depressive disorder, generalized anxiety disorder and psychotic disorders tended to have a later age of onset than OCD. Suicidal ideation within the last month was reported by 6.4% (n=200) of patients with OCD and 9.0% (n=314) reported a lifetime history of suicide attempt. In this large cross-continental study, comorbidity in OCD was common. The high rates of comorbid major depression and anxiety disorders emphasize the need for clinicians to assess and monitor for these disorders. Earlier ages of onset of OCD, specific phobia and social phobia may indicate some relatedness between these

    Cigarette smoking is more prevalent among individuals with psychiatric disorders than the general population. Obsessive-compulsive disorder (OCD) may be an intriguing exception, although no recent study has investigated this hypothesis in OCD patients. Moreover, it is unknown whether reduced smoking rates are present in unaffected first-degree relatives of OCD patients. We assessed smoking prevalence in adults with OCD and unaffected parents of youth with OCD (PYOCD). To this end, 113 adults with OCD completed online questionnaires assessing symptom severity and smoking status. Smoking status was obtained from an independent sample of 210 PYOCD assessed for psychiatric diagnoses. Smoking prevalence rates in adults with OCD (13.3%; n=15) and PYOCD (9.5%; n=20) samples were significantly lower than those found in representative samples of the general population (19-24%, all POCD subset without clinically significant depressive symptoms (n=54). Low prevalence of smoking in OCD may be familial and unique among psychiatric disorders, and might represent a possible state-independent OCD marker. Hypotheses concerning the uncharacteristically low prevalence rates are discussed with relation to OCD phenomenology and pathophysiology. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Obsessive-compulsive disorder (OCD) has a chronic course leading to huge impact in the patient's functioning. Suicidal thoughts and attempts are much more frequent in OCD subjects than once thought before. To empirically investigate whether the suicidal phenomena could be analyzed as a suicidality severity continuum and its association with obsessive-compulsive (OC) symptom dimensions and quality of life (QoL), in a large OCD sample. Cross-sectional study with 548 patients diagnosed with OCD according to the DSM-IV criteria, interviewed in the Brazilian OCD Consortium (C-TOC) sites. Patients were evaluated by OCD experts using standardized instruments including: Yale-Brown Obsessive-Compulsive Scale (YBOCS); Dimensional Yale-Brown Obsessive-Compulsive Scale (DYBOCS); Beck Depression and Anxiety Inventories; Structured Clinical Interview for DSM-IV (SCID); and the SF-36 QoL Health Survey. There were extremely high correlations between all the suicidal phenomena. OCD patients with suicidality had significantly lower QoL, higher severity in the "sexual/religious", "aggression" and "symmetry/ordering" OC symptom dimensions, higher BDI and BA scores and a higher frequency of suicide attempts in a family member. In the regression analysis, the factors that most impacted suicidality were the sexual dimension severity, the SF-36 QoL Mental Health domain, the severity of depressive symptoms and a relative with an attempted suicide history. Suicidality could be analyzed as a severity continuum and patients should be carefully monitored since they present with suicidal ideation. Lower QoL scores, higher scores on the sexual dimension and a family history of suicide attempts should be considered as risk factors for suicidality among OCD patients.

  18. Animal behavior as a conceptual framework for the study of obsessive-compulsive disorder (OCD).

    2012-06-01

    Research on affective disorders may benefit from the methodology of studying animal behavior, in which tools are available for qualitatively and quantitatively measuring and assessing behavior with as much sophistication and attention to detail as in the analysis of the brain. To illustrate this, we first briefly review the characteristics of obsessive-compulsive disorder (OCD), and then demonstrate how the quinpirole rat model is used as a conceptual model in studying human OCD patients. Like the rat model, the study of OCD in humans is based on video-telemetry, whereby observable, measurable, and relatively objective characteristics of OCD behavior may be extracted. In this process, OCD rituals are defined in terms of the space in which they are executed and the movements (acts) that are performed at each location or object in this space. Accordingly, OCD behavior is conceived of as comprising three hierarchical components: (i) rituals (as defined by the patients); (ii) visits to objects/locations in the environment at which the patient stops during the ritual; and (iii) acts performed at each object/location during visits. Scoring these structural components (behavioral units) is conveniently possible with readily available tools for behavioral description and analysis, providing quantitative and qualitative measures of the OCD hallmarks of repetition and addition, as well as the reduced functionality in OCD behavior. Altogether, the concept that was developed in the context of an animal model provides a useful tool that may facilitate OCD diagnosis, assessment and treatment, and may be similarly applied for other psychiatric disorders.

    In Obsessive Compulsive Disorder (OCD) current standard pharmacotherapies may be of limited efficacy. Non-conventional interventions such as Complementary and Alternative Medicine (CAM), self-help techniques, and lifestyle interventions are commonly used by sufferers of OCD, however to date no systematic review of this specific area exists. We conducted a systematic review of studies using CAM, self-help, and lifestyle interventions for treatment of OCD and trichotillomania (TTM). PubMed, PsycINFO, China Academic Journals Full-text Database, The Cochrane Library and CINAHL were searched (up to Jan 11th 2011), for controlled clinical trials using non-conventional interventions for OCD. A quality analysis using a purpose-designed scale and an estimation of effect sizes (Cohen's d) where data was available, were also calculated. The literature search revealed 14 studies that met inclusion criteria. Methodological quality of nutraceutical studies (nutrients and herbal medicines) were rated as high (mean 8.6/10), whereas mind-body or self-help studies were poorer (mean 6.1/10). In OCD, tentative evidentiary support from methodologically weak studies was found for mindfulness meditation (d=0.63), electroacupuncture (d=1.16), and kundalini yoga (d=1.61). Better designed studies using the nutrient glycine (d=1.10), and traditional herbal medicines milk thistle (insufficient data for calculating d) and borage (d=1.67) also revealed positive results. A rigorous study showed that N-acetylcysteine (d=1.31) was effective in TTM, while self-help technique "movement decoupling" also demonstrated efficacy (d=0.94). Mixed evidence was found for myo-inositol (mean d=0.98). Controlled studies suggest that St John's wort, EPA, and meridian-tapping are ineffective in treating OCD. While several studies were positive, these were un-replicated and commonly used small samples. This precludes firm confidence in the strength of clinical effect. Preliminary evidence however is encouraging

  20. Should OCD leave the anxiety disorders in DSM-V? The case for obsessive compulsive-related disorders.

    2008-01-01

    Recently in 2006, a group of experts in obsessive compulsive disorder (OCD) and obsessive compulsive-related disorders (OCRDs) convened in Washington, DC, to review existing data on the relationships between these various disorders, and to suggest approaches to address the gaps in our knowledge, in preparation for the upcoming Diagnostic and Statistical Manual (Fifth Edition) (DSM-V). As a result of this meeting, the Research Planning Agenda for DSM-V: OCRD Work Group suggested removing OCD from the anxiety disorders, where it is currently found. This proposal is in accordance with the current International Classification of Mental Disorders (ICD-10) classification of OCD as a separate category from the anxiety disorders. Although the ICD-10 places both OCD and the anxiety disorders under the umbrella category of "neurotic, stress-related, and somatoform disorders," they are two separate categories, distinct from one another. As OCD and other putative OCRDs share aspects of phenomenology, comorbidity, neurotransmitter/peptide systems, neurocircuitry, familial and genetic factors, and treatment response, it was proposed to create a new category in DSM-V entitled OCRDs. Alternatively, the OCRDs might be conceptualized as a new category within the broader category of anxiety disorders. Future studies are needed to better define the relationships among these disorders, and to study boundary issues for this proposed category. There are both advantages and disadvantages in creating a new diagnostic category in DSM-V, and these are discussed in this article.

  1. Increased decision thresholds enhance information gathering performance in juvenile Obsessive-Compulsive Disorder (OCD)

    2017-01-01

    Patients with obsessive-compulsive disorder (OCD) can be described as cautious and hesitant, manifesting an excessive indecisiveness that hinders efficient decision making. However, excess caution in decision making may also lead to better performance in specific situations where the cost of extended deliberation is small. We compared 16 juvenile OCD patients with 16 matched healthy controls whilst they performed a sequential information gathering task under different external cost conditions. We found that patients with OCD outperformed healthy controls, winning significantly more points. The groups also differed in the number of draws required prior to committing to a decision, but not in decision accuracy. A novel Bayesian computational model revealed that subjective sampling costs arose as a non-linear function of sampling, closely resembling an escalating urgency signal. Group difference in performance was best explained by a later emergence of these subjective costs in the OCD group, also evident in an increased decision threshold. Our findings present a novel computational model and suggest that enhanced information gathering in OCD can be accounted for by a higher decision threshold arising out of an altered perception of costs that, in some specific contexts, may be advantageous.

    To evaluate the impaired attention selection (Stroop interference effect) and general performance [reaction times (RTs)] on the Stroop task among methadone maintenance treatment (MMT) patients with obsessive compulsive disorder (OCD), pathological gambling (PG), both PG/OCD or none, and the influence if having ADHD. Eighty-six patients and 15 control subjects underwent the Stroop task, which measured RTs of condition-related words (color, obsessive compulsive disorder, pathological gambling, addiction) and neutral words. MMT patients had longer RTs on the Stroop task compared with controls. RTs were longer among patients with OCD and in those who abused drugs on the study day. The combined PG/OCD group had the longest RTs, but they were also characterized as abusing more drugs, being older, and having worse cognitive status. Stroop color interference differed only among MMT patients with ADHD, and it was higher among those with OCD than those without OCD. The modified condition-related Stroop did not show any interference effect of OCD, addiction, or gambling words. MMT patients had generally poorer performance, as indicated by longer RTs, that were related to clinical OCD, drug abuse, poor cognitive state, and older age. Patients with both clinical OCD and ADHD had a higher Stroop interference effect, which is a reflection of an attention deficit. In order to improve clinical approach and treatment of MMT patients, OCD and ADHD should be evaluated (and treated as needed).

    There is paucity of data on Quality of Life (QOL) in non-psychotic mental disorders. To assess the Quality of Life (QOL) in Obsessive Compulsive Disorder (OCD) and compare it with Dysthymic Disorder (DD). This hospital based cross-sectional study was conducted in 30 patients each diagnosed to have OCD and DD during October 2009 to September 2011 in a medical institution in Davanagere, Karnataka, India. DSM-IV-TR (Diagnostic statistical manual-IV-Text Revised) criteria was used for diagnosis of OCD and DD. Yale Brown Obsessive Compulsive Scale (Y-BOCS) and WHO QOL BREF (brief form) scales were used. Data was analysed by independent sample t-test. Overall QOL score was 51.07(SD=11.47) and 50.91(SD=7.41) in OCD and DD groups respectively. QOL score was comparatively low in psychological domain with score of 44.12(SD=14.14) and 45.10(12.35) in OCD and DD respectively. There was no significant difference in the QOL score of the two groups with respect to socio demographic variables in OCD group, but it was different with respect to place of residence in DD group (p0.05). Overall QOL score was average and there was no significant difference of QOL score between the OCD and DD groups implying that both these non-psychotic mental disorders may have same influence or effect on QOL of the subjects. Further analytical studies will explore the associated factors of QOL in OCD and DD.

    A body of evidence has supported that patients with obsessive-compulsive disorder (OCD) have increased rates of various neurological soft signs (NSS) compared to controls. Various lines of research has documented robust relationships between OCD and dissociative symptomatology. The study aimed to examine the associations between obsessive-compulsive symptoms, dissociative experiences alexithymia, and NSS. The study included thirty OCD patients and thirty healthy controls, matched for age, marital status, education, and income. The Neurological Evaluation Scale (NES), Padua Inventory-Revised (PI-R), Dissociative Experiences Scale (DES) and Toronto Alexithymia Scale (TAS-20) were administered. In comparison to healthy controls, patients with OCD had difficulty sequencing for complex motor acts and greater absorption/ imaginative involvement. Using latent class analysis, the study sample was classified into two homogenous subsets as mild NSS (n = 45) and severe NSS (n = 15). Majority of the participants who were grouped into severe NSS latent class were OCD patient (n = 14, 93.3%). Furthermore, those with severe NSS reported greater levels of alexithymia and more severe obsessive-compulsive symptoms, particularly precision. We concluded that relationships between OCD severity and NSS appear to be of crucial importance. Our data along with accumulated evidence suggest that OCD associated with pronounced NSS may represent a specific subtype of the disorder. Copyright © 2017 Elsevier B.V. All rights reserved.

    There is support for the role of gamma aminobutyric acid (GABA) in the etiology of mood disorders. Recent research has shown that hepatocyte growth factor (HGF) modulates GABAergic inhibition and seizure susceptibility. This study was designed to determine and correlate plasma levels of HGF and GABA as well as symptom severity in individuals with obsessive-compulsive disorder (OCD). Plasma from 15 individuals with OCD (9 males, 6 females;, mean age 38.7 years) and 17 neurotypical controls (10 males, 7 females; mean age 35.2 years) was assessed for HGF, GABA, urokinase plasminogen activator (uPA), and urokinase plasminogen activator receptor (uPAR) concentration using enzyme-linked immunosorbest assays ELISAs. Symptom severity was assessed in these OCD individuals and compared with HGF and GABA concentrations. In this preliminary study, individuals with OCD had significantly decreased HGF levels, decreased plasma levels of GABA and decreased uPA. We found that both uPA and uPAR levels correlate with HGF. Both low uPA and low uPAR levels correlate with high symptom severity in individuals with OCD. Low GABA levels in OCD individuals also correlate with high symptom severity. These results demonstrate a preliminary association between HGF, GABA, uPA levels, and OCD and suggest that plasma GABA and uPA levels are related to symptom severity in individuals with OCD.

    While there has been an abundance of quantitative studies that examine the clinical features and treatment modalities of obsessive-compulsive disorder (OCD), only a few qualitative research studies examining the experience of OCD have been documented. Our objectives were to explore and understand psychosocial aspects of OCD and to provide qualitative accounts of the condition and its treatment rather than concentrating on its psychopathology. We also wanted to locate the role cognitive behavioural therapy (CBT) played in the condition for our participants. Data for the study came from a series of nine semi-structured interviews carried out with individuals who self-identified as having OCD. Participants were recruited through two leading UK-based OCD charities. We used interpretative phenomenological analysis (IPA) to analyse the accounts and participants gave feedback as to the validity of the themes in early stages of analysis. We report two superordinate themes--Having OCD (with subordinate themes 'wanting to be normal and fit it', 'failing at life' and 'loving and hating OCD') and The Impact of Therapy (with subordinate themes of 'wanting therapy', 'finding the roots' and 'a better self'). Having OCD as a condition meant that individuals experienced a sense of overwhelming personal failure matched against age appropriate life cycle goals. This crisis of the self was bolstered by public and self-stigma about the condition. While clinical diagnosis and therapeutic interventions were significant, participants reported dialectical tensions experienced with OCD, pointing to the complexity of psychological functioning in the condition. © 2012 The British Psychological Society.

    Women with obsessive-compulsive disorder (OCD) often report that symptoms first appear or exacerbate during reproductive cycle events; however, little is known about these relationships. The goals of this study were to examine, in a US and a European female OCD sample, onset and exacerbation of OCD in reproductive cycle events, and to investigate the likelihood of repeat exacerbation in subsequent pregnancies and postpartum periods. Five hundred forty-two women (United States, n = 352; Dutch, n = 190) who met DSM-IV criteria for OCD, completed self-report questionnaires designed to assess OCD onset and symptom exacerbation associated with reproductive events. OCD onset occurred within 12 months after menarche in 13.0%, during pregnancy in 5.1%, at postpartum in 4.7%, and at menopause in 3.7%. Worsening of pre-existing OCD was reported by 37.6% of women at premenstruum, 33.0% during pregnancy, 46.6% postpartum, and 32.7% at menopause. Exacerbation in first pregnancy was significantly associated with exacerbation in second pregnancy (OR = 10.82, 95% CI 4.48-26.16), as was exacerbation in first postpartum with exacerbation in second postpartum (OR = 6.86, 95% CI 3.27-14.36). Results were replicated in both samples. Reproductive cycle events are periods of increased risk for onset and exacerbation of OCD in women. The present study is the first to provide significant evidence that exacerbation in or after first pregnancy is a substantial risk factor for exacerbation in or after a subsequent pregnancy. Further research is needed to identify factors related to exacerbation, so that physicians may provide appropriate recommendations to women regarding clinical issues involving OCD and reproductive cycle events. © 2014 Wiley Periodicals, Inc.

    Obsessive-compulsive disorder is a heterogeneous and debilitating condition, characterized by intrusive thoughts and compulsive repetition. Animal models of OCD are important tools that have the potential to contribute significantly to our understanding of the condition. Although there is consensus that pre-clinical models are valuable in elucidating the underlying neurobiology in psychiatric disorders, the current paper attempts to prompt ideas on how interpretation of animal behavior can be expanded upon to more effectively converge with the human disorder. Successful outcomes in psychopharmacology involves rational design and synthesis of novel compounds and their testing in well-designed animal models. As part of a special journal issue on OCD, this paper will 1) review the psycho-behavioral aspects of OCD that are of importance on how the above ideas can be articulated, 2) briefly elaborate on general issues that are important for the development of animal models of OCD, with a particular focus on the role and importance of context, 3) propose why translational progress may often be less than ideal, 4) highlight some of the significant contributions afforded by animal models to advance understanding, and 5) conclude by identifying novel behavioral constructs for future investigations that may contribute to the face, predictive and construct validity of OCD animal models. We base these targets on an integrative approach to face and construct validity, and note that the issue of treatment-resistance in the clinical context should receive attention in current animal models of OCD.

  10. From an animal model to human patients: An example of a translational study on obsessive compulsive disorder (OCD).

    The application of similar analyses enables a direct projection from translational research in animals to human studies. Following is an example of how the methodology of a specific animal model of obsessive-compulsive disorder (OCD) was applied to study human patients. Specifically, the quinpirole rat model for OCD was based on analyzing the trajectories of travel among different locales, and scoring the set of acts performed at each locale. Applying this analytic approach in human patients unveiled various aspects of OCD, such as the repetition and addition of acts, incompleteness, and the link between behavior and specific locations. It is also illustrated how the same analytical approach could be applicable to studying other mental disorders. Finally, it is suggested that the development of OCD could be explained by the four-phase sequence of Repetition, Addition, Condensation, and Elimination, as outlined in the study of ontogeny and phylogeny and applied to normal development of behavior. In OCD, this sequence is curtailed, resulting in the abundant repetition and addition of acts. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Background This study focused on hypotheses regarding the source of incompleteness in obsessive-compulsive disorder (OCD). For this, we had to document the behavioral manifestation of incompleteness in compulsive rituals, predicting that an exaggerated focus on acts that are appropriate for the task will support the hypothesis on heightened responsibility/perfectionism. In contrast, activity past the expected terminal act for the motor task would support the “stop signal deficiency” hypothesis. Methodology and Principal Findings We employed video-telemetry to analyze 39 motor OCD rituals and compared each with a similar task performed by a non-OCD individual, in order to objectively and explicitly determine the functional end of the activity. We found that 75% of OCD rituals comprised a “tail,” which is a section that follows the functional end of the task that the patients ascribed to their activity. The other 25% tailless rituals comprised a relatively high number and higher rate of repetition of non-functional acts. Thus, in rituals with tail, incompleteness was manifested by the mere presence of the tail whereas in tailless rituals, incompleteness was manifested by the reduced functionality of the task due to an inflated execution and repetition of non-functional acts. Conclusions The prevalence of activity after the functional end (“tail”) and the elevated non-functionality in OCD motor rituals support the “lack of stop signal” theories as the underlying mechanism in OCD. Furthermore, the presence and content of the tail might have a therapeutic potential in cognitive-behavior therapy. PMID:21966460

    Obsessive compulsive disorder (OCD) can be hugely disabling. Although very effective psychological treatments exist, many people delay years before seeking help or never seek treatment. There have been clinical observation and short questionnaire studies on why people delay, but little qualitative research exists on this complex subject. The present qualitative study aimed to identify the barriers to seeking treatment and the factors that encourage or push people to seek help for their OCD (positive and negative enablers). A qualitative, exploratory study using in-depth, individual, semi-structured interviews was conducted by a researcher with personal experience of OCD. Seventeen people with OCD, contacted through the charity OCD-UK, were interviewed about the factors that impacted on their decision to seek help or not. The interviews were analysed using thematic analysis. Barriers identified were stigma, 'internal / cognitive' factors, not knowing what their problem was, factors relating to their GP or treatment, and fear of criminalisation. Positive enablers identified were being supported to seek help, information and personal accounts of OCD in the media, and confidence in their GP. Negative enablers were reaching a crisis point and for some participants (whose intrusive thoughts were about harming children) feeling driven to seek treatment because of the nature of the thoughts, that is, seeking help to prevent the 'harm' they feared they were capable of doing. Participants identified a range of barriers and enablers that impacted on their decision to seek help or not. These give important indicators about the likely causes for delayed help seeking in OCD and ways in which people might be encouraged to seek help earlier. People with OCD may face a wide range of barriers to seeking help, including concern about the reaction of health professionals. The level of awareness, kindness, and understanding shown by first-line practitioners can be very important to

    Obsessive-compulsive disorder (OCD) is a distressing and often debilitating disorder characterized by obsessions, compulsions, or both that are time-consuming and cause impairment in social, occupational, or other areas of functioning. There are many published studies reporting higher risk of suicidality in OCD patients, as well as studies describing increased risk of suicidality in OCD patients with other comorbid psychiatric conditions such as major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). Existing case reports on OCD with suicide as the obsessive component describe patients with long standing diagnosis of OCD with suicidal ideations or previous suicide attempts. This report describes the case of a 28-year-old male, who works as a first responder, who presented with new onset symptoms characteristic of MDD and PTSD, with no past history of OCD or suicidality who developed OCD with suicidal obsessions. Differentiating between suicidal ideation in the context of other psychiatric illnesses and suicidal obsessions in OCD is critical to ensuring accurate diagnosis and timely provision of most appropriate treatment. The combination of exposure and response prevention therapy and pharmacotherapy with sertraline and olanzapine was effective in helping the patient manage the anxiety and distress stemming from the patient's OCD with suicidal obsession.

    Obsessive-compulsive disorder (OCD) is a debilitating mental health disorder that can substantially impact upon quality of life and everyday functioning. Guidelines recommend pharmacological and psychological treatments, using a cognitive behaviour therapy approach (CBT) including exposure and response prevention, but access has generally been poor. Low intensity psychological interventions have been advocated. The evidence base for these interventions is emerging but there is a paucity of information regarding practitioners' perceptions and experiences of supporting individuals with OCD using this approach. Qualitative interviews were undertaken with psychological wellbeing practitioners (PWPs) (n = 20) delivering low intensity psychological interventions for adults with OCD within the context of a large pragmatic effectiveness trial. Interviews explored the feasibility and acceptability of delivering two interventions; guided self-help and supported computerised cognitive behaviour therapy (cCBT), within Improving Access to Psychological Therapies (IAPT) services in NHS Trusts. Interviews were recorded with consent, transcribed and analysed using thematic analysis. PWPs acknowledged the benefits of low intensity psychological interventions for individuals experiencing OCD symptoms on an individual and population level. Offering low intensity support provided was perceived to have the opportunity to overcome existing service barriers to access treatment, improve patient choice and flexibility. Professional and service relevant issues were also recognised including self-beliefs about supporting people with OCD and personal training needs. Challenges to implementation were recognised in relation to practitioner resistance and intervention delivery technical complications. This study has provided insight into the implementation of new low intensity approaches to the management of OCD within existing mental health services. Benefits from a practitioner, service

    A large body of literature suggests that some symptoms of obsessive-compulsive disorder (OCD) result from mnemonic dysfunctions. The present study tested various formulations of the memory deficit hypothesis considering important moderators, such as depression and response slowing. Thirty-two OCD patients and 32 healthy controls were presented verbal or nonverbal instructions for actions (e.g. simple gestures). These actions should either be performed or imagined. For recognition, previously presented as well as novel actions were displayed. Decisions had to be made whether an action was previously displayed (verbally vs. nonverbally) or not and whether an action was performed or imagined (internal source memory). Moreover, both judgments required confidence ratings. Groups did not differ in memory accuracy and metamemory for verbally presented material. Patients displayed some impairment for nonverbally presented material and imagined instructions, which, however, could be fully accounted for by response slowing and depressive symptoms. The study challenges the view that primary memory deficits underlie OCD or any of its subtypes. We claim that research should move forward from the mere study of objective impairment to the assessment of cognitive performance in conjunction with personality traits such as inflated responsibility.

    Some individuals with obsessive-compulsive disorder (OCD) have autistic-like traits, including deficits in social and communication behaviors (pragmatics). The objective of this study was to determine if pragmatic impairment aggregates in OCD families and discriminates a clinically and genetically distinct subtype of OCD. We conducted clinical examinations on, and collected DNA samples from, 706 individuals with OCD in 221 multiply affected OCD families. Using the Pragmatic Rating Scale (PRS), we compared the prevalence of pragmatic impairment in OCD-affected relatives of probands with and without pragmatic impairment. We also compared clinical features of OCD-affected individuals in families having at least one, versus no, individual with pragmatic impairment, and assessed for linkage to OCD in the two groups of families. The odds of pragmatic impairment were substantially greater in OCD-affected relatives of probands with pragmatic impairment. Individuals in high-PRS families had greater odds of separation anxiety disorder and social phobia, and a greater number of schizotypal personality traits. In high-PRS families, there was suggestive linkage to OCD on chromosome 12 at marker D12S1064 and on chromosome X at marker DXS7132 whereas, in low-PRS families, there was suggestive linkage to chromosome 3 at marker D3S2398. Pragmatic impairment aggregates in OCD families. Separation anxiety disorder, social phobia, and schizotypal personality traits are part of a clinical spectrum associated with pragmatic impairment in these families. Specific regions of chromosomes 12 and X are linked to OCD in high-PRS families. Thus, pragmatic impairment may distinguish a clinically and genetically homogeneous subtype of OCD. © 2014 Wiley Periodicals, Inc.

    OCD? Not Me! is a novel, web-based, self-guided intervention designed to treat obsessive-compulsive disorder (OCD) in young people aged 12-18, using the principles of exposure and response prevention. The current paper presents the protocol for the development of the programme and for an open trial that will evaluate the effectiveness of this programme for OCD in young people, and associated distress and symptom accommodation in their parents and caregivers. We will measure the impact of the OCD? Not Me! programme on OCD symptoms using the Children's Florida Obsessive Compulsive Inventory (C-FOCI), and both the self-report and parent report of the Children's Obsessional Compulsive Inventory-Revised (ChOCI-R). The impact of the programme on OCD-related functional impairment will be measured using the parent report of the Child Obsessive-Compulsive Impact Scale-Revised (COIS-R). Secondary outcome measures include the Rosenberg Self-Esteem Scale and the Youth Quality of Life-Short Form (YQoL-SF). The 21-item Depression Anxiety Stress Scales (DASS-21) will be used to measure the impact of the programme on parent/caregiver distress, while the Family Accommodation Scale (FAS) will be used to measure change in family accommodation of OCD symptoms. Multilevel mixed effects linear regression will be used to analyse the impact of the intervention on the outcome measures. This study has been approved by the Curtin University Human Research Ethics Committee. The results of the study will be reported in international peer-reviewed journals.

    Obsessive-compulsive disorder (OCD) is characterized by recurrent obtrusive and repetitive acts typically occurred following anxiety. In the last two decades, studies done on the gene sequences, large-scale and point mutations and gene-gene, gene-environment and gene-drug interactions have led to the discovery of hundreds of genes associated with OCD. Although each gene in turn is a part of the etiology of this disorder; however, OCD, like other mental disorders is complex and a comprehensive and integrated view is necessary to understand its genetic basis. In this study, through an extensive review of existing published studies, all genes associated with OCD were found. Then, in order to integrate the results, all the interactions between these genes were explored and the achievement was represented as an interactive genetic network. Furthermore, the reconstructed network was analyzed. It was found that GRIN2A, GRIN2B and GRIA2 are the most central nodes in the network. Functional and pathway enrichment analysis showed that glutamate-related pathways are the main deficient systems in patients with OCD. By studying genes shared between OCD and other diseases, it was cleared that OCD, epilepsy and some types of cancer have the most number of shared genes. The results of this study, in addition to reviewing the available results as a comprehensive and integrated manner, provide new hypotheses for future studies.

    Greater obsessive-compulsive (OC) symptom severity may be associated with poor social adjustment. Rather than possessing deficits in social skill per se, OCD patients may be more socially isolative in the presence of normal controls. We aimed to apply a novel social interaction challenge (SIC) to an established animal model of OCD, viz., the deer mouse, to assess complex social behavior in animals by investigating group sociability and its response to chronic escitalopram treatment (50 mg/kg/day × 28 days), both within and between non (N)- (viz., normal) and high (H)- (viz., OCD-like) stereotypical cohorts. Using automated screening, we scored approach behavior, episodes of proximity, duration of proximity, and relative net weighted movement. H animals socialized more with one another within cohort in all of the above parameters compared to the within-cohort behavior of N animals. Furthermore, the social behavior of H animals toward one another, both within and between cohort demonstrated significant improvements following chronic escitalopram treatment. However, the study also demonstrates that the social interaction between H and N animals remain poor even after chronic escitalopram treatment. To conclude, findings from the current investigation support clinical data demonstrating altered sociability in patients with OCD.

    Semantic network models suggest that individuals with obsessive-compulsive disorder (OCD) process words with multiple meanings (e.g., "knife") more likely in an OC-related (i.e., "weapon") than in a neutral way (i.e., "cutlery"). Initial evidence was found in an online study. The aim of the current study was to investigate semantic networks in a clinical OCD sample and particularly to identify whether changes in semantic networks following the add-on intervention association splitting (AS) exceeded changes expected through cognitive behavioral therapy (CBT) alone. An association task was presented to 36 healthy controls and 70 OCD patients over a period of eight weeks with OCD patients receiving CBT and an add-on intervention (randomized allocation to either AS or a computerized cognitive training). Participants were asked to generate up to five associations to standardized (OC-relevant, negative, neutral) and individual cue words. Associations were rated with regard to OC-relevance and valence. Analyses revealed that OCD participants produced a) significantly more OC-relevant associations and b) more negative associations than controls for cue words. In the OCD sample, the OC-relevance and valence of associations changed after therapy for personal cue words. This effect was associated with AS at statistical trend level. No clinical control group was recruited; no inter-rater reliability was assessed for the association task. Further evidence for biased associative networks in OCD was found. Associations of individually chosen cue words proved to be modifiable by therapy. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Obsessive Compulsive Disorder (OCD) is a psychiatric disorder with considerable morbidity and mortality. This condition disables many individuals and is often refractory to treatment. Research suggests that serotonin plays a role in OCD symptom reduction. We present a case of an individual who successfully used psilocybin, a serotonergic agent, to reduce the core symptoms of OCD for several years. Although not endorsing this form of treatment, we feel that the successful use of this agent highlights the role of serotonergic factors in OCD and the need for further, legitimate research into the value of psilocybin in the treatment of anxiety disorders.

    Compulsive behaviors are driven by repetitive urges and typically involve the experience of limited voluntary control over these urges, a diminished ability to delay or inhibit these behaviors, and a tendency to perform repetitive acts in a habitual or stereotyped manner. Compulsivity is not only a central characteristic of obsessive-compulsive disorder (OCD) but is also crucial to addiction. Based on this analogy, OCD has been proposed to be part of the concept of behavioral addiction along with other non-drug-related disorders that share compulsivity, such as pathological gambling, skin-picking, trichotillomania and compulsive eating. In this review, we investigate the neurobiological overlap between compulsivity in substance-use disorders, OCD and behavioral addictions as a validation for the construct of compulsivity that could be adopted in the Research Domain Criteria (RDoC). The reviewed data suggest that compulsivity in OCD and addictions is related to impaired reward and punishment processing with attenuated dopamine release in the ventral striatum, negative reinforcement in limbic systems, cognitive and behavioral inflexibility with diminished serotonergic prefrontal control, and habitual responding with imbalances between ventral and dorsal frontostriatal recruitment. Frontostriatal abnormalities of compulsivity are promising targets for neuromodulation and other interventions for OCD and addictions. We conclude that compulsivity encompasses many of the RDoC constructs in a trans-diagnostic fashion with a common brain circuit dysfunction that can help identifying appropriate prevention and treatment targets.

    OCD is characterised by recurrent obsessions and compulsions that result in severe distress and increased risk for comorbidity. Recently published findings have indicated that the neuronal cadherin gene (CDH2) plays a role in the development of canine OCD, and led us to investigate the human ortholog, CDH2, in a human OCD cohort. Seven CDH2 polymorphisms were selected and genotyped in a South African Caucasian cohort of 234 OCD patients and 180 healthy controls using TaqMan assays. Polymorphisms were analysed in a single-locus and haplotypic context. Of the seven polymorphisms, two reached statistical significance for OCD under additive and codominant models of inheritance (rs1120154 and rs12605662). CDH2 SNP, rs1120154, C-allele carriers were found to be significantly associated with lower risk to develop OCD compared to TT-homozygotes (OR = 0.49; 95% CI: 0.32-0.75; p OCD compared to TT-homozygotes (OR = 0.46; 95% CI: 0.30-0.71; p OCD diagnosis (*rs8087457-rs1148374: A-T). Polymorphisms within the CDH2 gene are associated with susceptibility to OCD in a South African cohort.

    Background Although the relationship between obsessive compulsive disorder (OCD) and obsessive compulsive personality disorder (OCPD) has long been debated, clinical samples of OCD (without OCPD) and OCPD (without OCD) have never been systematically compared. We studied whether individuals with OCD, OCPD, or both conditions differ on symptomatology, functioning, and a measure of self-control: the capacity to delay reward. Methods 25 OCD, 25 OCPD, 25 comorbid OCD+OCPD, and 25 healthy controls (HC) completed clinical assessments and a validated intertemporal choice task that measures capacity to forego small immediate rewards for larger delayed rewards. Results OCD and OCPD subjects both showed impairment in psychosocial functioning and quality of life, as well as compulsive behavior, but only subjects with OCD reported obsessions. Individuals with OCPD, with or without comorbid OCD, discounted the value of delayed monetary rewards significantly less than OCD and HC. This excessive capacity to delay reward discriminates OCPD from OCD, and is associated with perfectionism and rigidity. Conclusions OCD and OCPD are both impairing disorders marked by compulsive behaviors, but they can be differentiated by the presence of obsessions in OCD and by excessive capacity to delay reward in OCPD. That individuals with OCPD show less temporal discounting (suggestive of excessive self-control) whereas prior studies have shown that individuals with substance use disorders show greater discounting (suggestive of impulsivity) supports the premise that this component of self-control lies on a continuum in which both extremes (impulsivity and overcontrol) contribute to psychopathology.

In this study, we compared the performances of OCD patients and normal subjects using a factorial interpretation of the Wechsler Memory Scale. Our results do not demonstrate significant memory impairment in OCD patients but point to the possibility of frontal lobe dysfunction as a factor in the pathophysiology of OCD.

Hence, to study and determine family factors like high expressed emotion (EE and family dysfunction are essential. These two factors play a significant role in the relapse and course of OCD. Aim: The aim was to study the relationship between family function, EE and OCD. Materials and Methods: The sample included 30 patients who were diagnosed with OCD using International Classification of Diseases-10 Diagnostic Criteria for Research criteria. Yale-Brown obsessive compulsive scale was used to assess the severity of OCD. EE was assessed in cases using Family Emotional Involvement and Criticism Scale and family function was assessed in cases using the family interaction pattern scale (FIPS. Statistical analysis was performed using Statistical Packages for Social Science. Patient and caregivers of the patients were assessed on self-developed socio-demographic proforma. Pearson co-relation co-efficient test was used to study the correlation between OCD, high EE and family dysfunction. Results: The result showed that there are significant correlations between high EE, family dysfunction and OCD. The Pearson correlation co-efficient between OCD and EE shows a significant correlation between the high EE of the caregiver and OCD with P < 0.01. The Pearson correlation co-efficient between OCD and Family Interaction Pattern Scale shows a significant correlation between the family dysfunction of the caregiver and OCD. Conclusion: Impaired family function and high EE in caregivers associated with OCD. Thus clinical interventions may improve the functional abilities of the caregivers.

    Clinical data are largely focused on depressive comorbidity in OCD. However in practice, treating resistant or severe OCD sufferers revealed many cases who seem to have an authentic OCD with a hidden comorbid bipolar disorder. Most reports had evaluated the OCD comorbidity in unipolar and bipolar mood disorders (Kruger et al., 1995; Chen et Dilsaver, 1995). The only investigation in clinical population focused on the reverse issue was conducted in Pisa. Perugi et al. (1997) have showed in a consecutive series of 315 OCD outpatients, that 15.7% presented a bipolar comorbidity, mostly with BP-II disorder. Further analyses suggested that when comorbidity occurs with bipolar and unipolar depression, it has a differential impact on the clinical picture and course of OCD. The rate of bipolar comorbidity in OCD was analyzed in a recent epidemiological survey undertaken by the French Association of patients suffering from OCD (FA-OCD or AFTOC in French). In a sample of 453 OCD patients, 76% had suffered from a major depression, 11% from bipolar disorder (DSM IV mania or hypomania), 30% from hypomania (cases that obtained a score > or = 10 on the self-rated Angst Hypomania Checklist). According to the score > or = 10 on Self-rated Questionnaire for Cyclothymic Temperament, 50% were classified as cyclothymic. The self-assessment of soft-bipolar dimensions, such as hypomania and cyclothymia was previously validated in a multi-site study in major depression (Hantouche et al., 1998). Further analyses showed that comorbidity with soft bipolarity was characterized by significant interactions with high levels of impulsivity, anger attacks and suicidal behavior. In order to confirm these data, another cohort (n = 175 patients treated by psychiatrists for OCD) was formed and named "PSY-OCD". Comparative analyses between the two populations allowed showing very few demographic and clinical differences. The frequency rate of "bipolar OCD" was equivalent in both populations: BP

  10. The link between ADHD-like inattention and obsessions and compulsions during treatment of youth with OCD.

    Attention-deficit/hyperactivity disorder (ADHD) has been found to be highly comorbid in children and adolescents with obsessive-compulsive disorder (OCD). Some have proposed, however, that obsessive anxiety may cause inattention and executive dysfunction, leading to inappropriate ADHD diagnoses in those with OCD. If this were the case, these symptoms would be expected to decrease following successful OCD treatment. The present study tested this hypothesis and evaluated whether ADHD symptoms at baseline predicted OCD treatment response. Obsessive-compulsive and ADHD symptoms were assessed in 50 youth enrolled in a randomized controlled trial investigating selective serotonin reuptake inhibitor and cognitive behavioral treatment. Repeated-measures analysis of variance (RMANOVA) revealed that ADHD symptoms at baseline do not significantly predict treatment outcome. A multivariate RMANOVA found that OCD treatment response moderated change in inattention; participants who showed greater reduction in OCD severity experienced greater reduction in ADHD-inattentive symptoms, while those with less substantial reduction in obsessions and compulsions showed less change. These findings suggest that children and adolescents with OCD and inattention may experience meaningful improvements in attention problems following OCD treatment. Thus, in many youth with OCD, inattention may be inherently tied to obsessions and compulsions. Clinicians may consider addressing OCD in treatment before targeting inattentive-type ADHD.

    Full Text Available Objective: To explore the effect of comorbid obsessive-compulsive personality disorder (OCPD on response inhibition functions in patients with obsessive-compulsive disorder (OCD. Methods: Forty-five obsessive-compulsive patients with obsessive-compulsive personality disorder (OCD + OCPD, 42 obsessive-compulsive patients without obsessive-compulsive personality disorder (OCD - OCPD and 54 healthy volunteers were selected for the stop-signal task. Results: Obsessive-compulsive patients with obsessive-compulsive personality disorder had a higher score of depression and anxiety and more severe obsessive-compulsive symptoms than that of obsessive-compulsive patients without obsessive-compulsive personality disorder. The two groups of obsessive-compulsive patients of had a greater stop-signal reaction time (SSRT during the inhibition process than the healthy volunteers of the control group (OCD + OCPD: 221.45 ± 31.78; OCD - OCPD: 218.36 ± 31.78; Controls: 199.29 ± 22.80; p < 0.05. However, no significant difference was found between the two groups of obsessive-compulsive patients. Conclusion: The findings show that the comorbid obsessive-compulsive personality disorder has no effect on response inhibition function of obsessive-compulsive patients.

    Previous research has demonstrated that comorbid obsessive-compulsive personality disorder (OCPD) in patients with obsessive-compulsive disorder (OCD) is associated with greater overall OCD severity, functional impairment, and poorer treatment outcomes (Coles et al., 2008; Lochner et al., 2010; Pinto, 2009). However, research has only examined the effects of OCPD categorically and has yet to thoroughly examine the impact of individual OCPD characteristics dimensionally. Thus, the present study sought to investigate the relationships between various OCPD-related dimensions (e.g., perfectionism, rigidity) and OCD symptomology and severity. The study recruited a sample of OCD patients (n=51) in the OCD units of two residential treatment facilities. Findings yielded significant relationships between OCD severity and the following OCPD dimensions: flexibility, doubts about actions (a dimension of perfectionism), and hoarding. Interpretations of these results and the implications for diagnosis, prognosis, and treatment outcome are discussed. Furthermore, the current study provides insight into a unique perspective which leaves room for more symptom overlap and variability between OCD and OCPD. Published by Elsevier Ltd.

    The overlap between obsessive compulsive personality disorder (OCPD) and obsessive compulsive disorder (OCD) has received increasing recognition and continues to be a source of much debate. With the advent of new research methodologies, researchers have attempted to distinguish whether OCPD and OCD are two distinct phenomena that can co-occur or whether they are similar, overlapping constructs. MEDLINE was used to systematically review the OCPD and OCD literature published between 1991 and 2004. Using the more stringent DSM-IV criteria, results from OCD clinical samples suggest that the majority of individuals with OCD (75%) do not have OCPD. Similarly, results from personality disorder samples suggest that the majority of individuals with OCPD (80%) do not have OCD. While there is evidence that OCD and OCPD are linked, the literature does not support either one as a necessary or sufficient component of the other.

    The present study examined whether the comorbidity of obsessive-compulsive personality disorder (OCPD) and obsessive-compulsive disorder (OCD) constitute a specific subtype of OCD. The study sample consisted of 146 consecutive outpatients with a DSM-IV diagnosis of OCD. Diagnoses were established using MINI, IPDE, YBOCS and YBOCS-SC. OCD patients with comorbid OCPD were compared with OCD patients without OCPD on various sociodemographic and clinical variables. Almost one third of the OCD subjects met criteria for comorbid OCPD. OCD+OCPD patients had a significantly earlier age at onset of initial OC symptoms, earlier age at onset of OCD and more obsessions and compulsions than pure obsessions compared to the patients with OCDOCPD. OCD+OCPD patients also had a higher rate of comorbidity with avoidant personality disorder and showed more impairment in global functioning. There were not differences between the two sub-groups on severity of OCD symptoms and also on type of OCD onset. Our results indicate that the comorbidity of OCD with OCPD is associated with a number of specific clinical characteristics of OCD. These findings in conjunction with of current clinical, family and genetic studies provide some initial evidence that OCD comorbid with OCPD constitute a specific subtype of OCD.

    Due to its heterogeneous phenomenology, obsessive-compulsive disorder (OCD) has been subtyped. However, these subtypes are not mutually exclusive. This study presents an alternative subtyping approach by deriving non-overlapping OCD subtypes. A pure compulsive and a mixed obsessive-compulsive subtype (including subjects manifesting obsessions with/without compulsions) were analyzed with respect to a broad pattern of psychosocial risk factors and comorbid syndromes/diagnoses in three representative Swiss community samples: the Zurich Study (n = 591), the ZInEP sample (n = 1500), and the PsyCoLaus sample (n = 3720). A selection of comorbidities was examined in a pooled database. Odds ratios were derived from logistic regressions and, in the analysis of pooled data, multilevel models. The pure compulsive subtype showed a lower age of onset and was characterized by few associations with psychosocial risk factors. The higher social popularity of the pure compulsive subjects and their families was remarkable. Comorbidities within the pure compulsive subtype were mainly restricted to phobias. In contrast, the mixed obsessive-compulsive subtype had a higher prevalence and was associated with various childhood adversities, more familial burden, and numerous comorbid disorders, including disorders characterized by high impulsivity. The current comparison study across three representative community surveys presented two basic, distinct OCD subtypes associated with differing psychosocial impairment. Such highly specific subtypes offer the opportunity to learn about pathophysiological mechanisms specifically involved in OCD.

    Cognitive neuroscience investigates neural responses to cognitive and emotional probes, an approach that has yielded critical insights into the neurobiological mechanisms of psychiatric disorders. This article reviews some of the major findings from neuroimaging studies using a cognitive neuroscience approach to investigate obsessive-compulsive disorder (OCD). It evaluates the consistency of results and interprets findings within the context of OCD symptoms, and proposes a model of OCD involving inflexibility of internally focused cognition. Although further research is needed, this body of work probing cognitive-emotional processes in OCD has already shed considerable light on the underlying mechanisms of the disorder.

    The authors assessed the prevalence of compulsive buying (CB) among patients presenting an obsessive-compulsive disorder (OCD). They compared the buying style of patients with and without CB. One thousand five hundred consecutive patients were assessed by a general practitioner in Paris (France). Sixty patients presenting with OCD were included. Patients with CB associated with OCD (n = 14) were compared with those with "pure" OCD (n = 46). Sixty patients paired for sex and age and free from OCD, depression, and anxiety were also recruited among the clients of the same general practitioner. We compared 3 groups: controls, patients with OCD, and patients with OCD + CB. Prevalence of CB was 23% (14 cases) among patients with OCD and 6% (4 cases) in controls (chi(2)(1) = 5.3, P = .02). Patients presenting with OCD + CB had a higher number of Diagnostic and Statistical Manual of Mental Disorders, Revised Fourth Edition diagnostic criteria for OCD than patients with pure OCD (6.1 and 5.4, respectively, P = .001). Depression was more frequent in the OCD + CB group (78%) than in the OCD group (42%) and in controls (10%) (P = .02). Patients from the OCD + CB group had higher score at the CAGE questionnaire than those of the OCD group (2 vs 0.7, P = .003). Patients with OCD + CB considered 42% of their purchases as occasions not to be passed up compared with 15.4% in the OCD group and 8.6% in controls. OCD+CD patients used the items they bought after a longer delay than controls and patients with pure OCD (8.2 vs 3 and 3.1 days, respectively). Compulsive buying is more frequent in OCD than in controls. Patients presenting with OCD + CB show more depressive disorders and drink more alcohol. They are more highly implicated in the items they buy and they are more often disappointed by the items once they possess them.

    Randomised and sham-controlled trials (RCTs) of repetitive transcranial magnetic stimulation (rTMS) in the treatment of obsessive-compulsive disorder (OCD) have yielded conflicting results, which may be due to the variability in rTMS parameters used. We performed an updated systematic review and meta-analysis on the effectiveness of rTMS for the treatment of OCD and aimed to determine whether certain rTMS parameters, such as cortical target, may be associated with higher treatment effectiveness. After conducting a systematic literature review for RCTs on rTMS for OCD through to 1 December 2016 using MEDLINE, PubMed, Web of Science, PsycINFO, Google, and Google Scholar, we performed a random-effects meta-analysis with the outcome measure as pre-post changes in Yale-Brown Obsessive Compulsive Scale (Y-BOCS) scores. To determine whether rTMS parameters may have influenced treatment effectiveness, studies were further analysed according to cortical target, stimulation frequency, and length of follow-up. Data were obtained from 18 RCTs on rTMS in the treatment of OCD. Overall, rTMS yielded a modest effect in reducing Y-BOCS scores with Hedge's g of 0.79 (95% CI = 0.43-1.15, p OCD. The therapeutic effects of rTMS also appear to persist post-treatment and may offer beneficial long-term effectiveness. With our findings, it is suggested that future large-scale studies focus on the supplementary motor area and include follow-up periods of 12 weeks or more.

    We assessed correlates of obsessive-compulsive (OCPD), schizotypal (SPD) and borderline (BPD) personality disorders in 110 obsessive-compulsive disorder (OCD) patients. We found OCD patients with OCPD (20.9%) to exhibit higher rates of hoarding and bipolar disorders, increased severity of hoarding and symmetry, lower prevalence of unacceptable thoughts involving sex and religion and less non-planning impulsivity. Conversely, OCD patients with SPD (13.6%) displayed more frequently bipolar disorder, increased severity of depression and OCD neutralization, greater prevalence of "low-order" behaviors (i.e., touching), lower low-planning impulsivity and greater "behavioral" compulsivity. Finally, in exploratory analyses, OCD patients with BPD (21.8%) exhibited lower education, higher rates of several comorbid psychiatric disorders, greater frequency of compulsions involving interpersonal domains (e.g. reassurance seeking), increased severity of depression, anxiety and OCD dimensions other than symmetry and hoarding, more motor and non-planning impulsivity, and greater "cognitive" compulsivity. These findings highlight the importance of assessing personality disorders in OCD samples. Copyright © 2015 Elsevier Ltd. All rights reserved.

    It has been proposed that certain Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders share overlapping clinical features, genetic contributions, and treatment response and fall within an "obsessive-compulsive" spectrum. Obsessive-compulsive personality disorder (OCPD) resembles obsessive-compulsive disorder (OCD) and other spectrum disorders in terms of phenomenology, comorbidity, neurocognition, and treatment response. This article critically examines the nosological profile of OCPD with special reference to OCD and related disorders. By viewing OCPD as a candidate member of the obsessive-compulsive spectrum, we gain a fresh approach to understanding its neurobiology, etiology, and potential treatments.

    Although the relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) has long been debated, clinical samples of OCD (without OCPD) and OCPD (without OCD) have never been systematically compared. We studied whether individuals with OCD, OCPD, or both conditions differ on symptomatology, functioning, and a measure of self-control: the capacity to delay reward. Twenty-five OCD, 25 OCPD, 25 comorbid OCD + OCPD, and 25 healthy control subjects completed clinical assessments and a validated intertemporal choice task that measures capacity to forego small immediate rewards for larger delayed rewards. OCD and OCPD subjects both showed impairment in psychosocial functioning and quality of life, as well as compulsive behavior, but only subjects with OCD reported obsessions. Individuals with OCPD, with or without comorbid OCD, discounted the value of delayed monetary rewards significantly less than OCD and healthy control subjects. This excessive capacity to delay reward discriminates OCPD from OCD and is associated with perfectionism and rigidity. OCD and OCPD are both impairing disorders marked by compulsive behaviors, but they can be differentiated by the presence of obsessions in OCD and by excessive capacity to delay reward in OCPD. That individuals with OCPD show less temporal discounting (suggestive of excessive self-control), whereas prior studies have shown that individuals with substance use disorders show greater discounting (suggestive of impulsivity), supports the premise that this component of self-control lies on a continuum in which both extremes (impulsivity and overcontrol) contribute to psychopathology. © 2013 Society of Biological Psychiatry Published by Society of Biological Psychiatry All rights reserved.

OCPD is statistically significantly more frequent in patients with OCD than in those with Panic and MDD. The distribution of single criteria of OCPD in the three groups does not differ significantly. Discriminant analysis selects a list of items that provide a correct classification rate of 66% based on OCPD criteria selected by canonical function. OCD patients with and without OCPD do not differ in sex, age of onset, duration of illness, positive family history for Tics disorder/Tourette syndrome (TS), or morbidity risk for OCD.

    In this study we examined the convergence between obsessive-compulsive personality disorder (OCPD) criteria and obsessive-compulsive disorder (OCD). Baseline assessments of 629 participants of the Collaborative Longitudinal Personality Disorders Study were used to examine the associations between OCPD criteria and diagnoses of OCD. Three of the eight OCPD criteria--hoarding, perfectionism, and preoccupation with details--were significantly more frequent in subjects with OCD (n = 89) than in subjects without OCD (n = 540). Logistic regressions were used to predict the probability of each OCPD criterion as a function of Axis I diagnoses (OCD, additional anxiety disorders, and major depressive disorder). Associations between OCD and these three OCPD criteria remained significant in the logistic regressions, showing unique associations with OCD and odds ratios ranging from 2.71 to 2.99. In addition, other anxiety disorders and major depressive disorder showed few associations with specific OCPD criteria. This study suggests variability in the strength of the relationships between specific OCPD criteria and OCD. The findings also support a unique relationship between OCPD symptoms and OCD, compared to other anxiety disorders or major depression. Future efforts to explore the link between Axis I and Axis II disorders may be enriched by conducting analyses at the symptom level.

    It is often suggested that, in general, co-morbid personality disorders are likely to interfere with CBT based treatment of Axis I disorders, given that personality disorders are regarded as dispositional and are therefore considered less amenable to change than axis I psychiatric disorders. The present study aimed to investigate the impact of co-occurring obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) on cognitive-behavioural treatment for OCD. 92 individuals with a diagnosis of OCD participated in this study. Data were drawn from measures taken at initial assessment and following cognitive-behavioural treatment at a specialist treatment centre for anxiety disorders. At assessment, participants with OCD and OCPD had greater overall OCD symptom severity, as well as doubting, ordering and hoarding symptoms relative to those without OCPD; however, participants with co-morbid OCD and OCPD demonstrated greater treatment gains in terms of OCD severity, checking and ordering than those without OCPD. Individuals with OCD and OCPD had higher levels of checking, ordering and overall OCD severity at initial assessment; however, at post-treatment they had similar scores to those without OCPD. The implications of these findings are discussed in the light of research on axis I and II co-morbidity and the impact of axis II disorders on treatment for axis I disorders.

    Studies have shown a high prevalence of autistic spectrum traits in both children and adults with psychiatric disorders; however the prevalence rate has not yet been investigated in young children with OCD. The aim of the current study was to (1) determine whether ASD traits indicated by the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS) were elevated in young children with OCD who do not have a specific ASD diagnosis and (2) determine if ASD traits were associated with OCD severity. Participants (N = 127) were children ages 5-8 years enrolled in the pediatric obsessive-compulsive disorder treatment study for young children (POTS Jr.). Results indicated that the SRS showed elevated autistic traits in the sample and was associated with OCD severity whereas the SCQ did not indicate heightened ASD symptoms. Implications of these results are discussed.

    Perfectionism and obsessionality are core features of eating disorders (ED), yet the nature of their relation remains unknown. Understanding the relation between these traits may enhance our ability to identify relevant behavioral endophenotypes for ED. Six-hundred seven individuals with anorexia and bulimia nervosa from the International Price Foundation Genetic Study were assessed for perfectionism, obsessive-compulsive personality disorder (OCPD), and obsessive-compulsive disorder (OCD). No differences were found across ED subtypes in the prevalence of OCPD and OCD, nor with the association between OCD and OCPD. Perfectionism scores were highest in individuals with OCPD whether alone or in combination with OCD. Perfectionism appears to be more closely associated with obsessive-compulsive personality symptoms rather than OCD. The pairing of perfectionism with OCPD may be a relevant core behavioral feature underlying vulnerability to ED. Copyright 2005 by Wiley Periodicals, Inc.

    Over the last years evidence on the overlap between tic-disorders (TD) and obsessive compulsive behavior/disorder (OCB/OCD) has increased. The main focus of research have been the phenomenological and epidemiological similarities and differences in samples of different age, primary diagnosis (TD vs. OCD) including the co-occurrence of both. Unfortunately, only a minority of studies included all three groups (TD, TD + OCD, OCD). Nevertheless, new insight concerning possible subtypes for both TD and OCD has been gained. While some authors concentrated on OCD with/without tics we will summarize the field of TD and OCB/OCD from the viewpoint of tics, since OCB plays an important role in patients with TD. Thereby we will not only sharpen the clinicans' awareness of known differences in phenomenology, epidemiology, genetics and neurobiology, aimed to improve their diagnoses and treatment but also highlight the gaps of knowledge and discuss possibilities for further research in this field.

    Obsessive-compulsive disorder (OCD) is a clinical syndrome whose hallmarks are excessive, anxiety-evoking thoughts and compulsive behaviors that are generally recognized as unreasonable, but which cause significant distress and impairment. When these are the exclusive symptoms, they constitute uncomplicated OCD. OCD may also occur in the context of other neuropsychiatric disorders, most commonly other anxiety and mood disorders. The question remains as to whether these combinations of disorders should be regarded as independent, cooccurring disorders or as different manifestations of an incompletely understood constellation of OCD spectrum disorders with a common etiology. Additional considerations are given here to two potential etiology-based subgroups: (i) an environmentally based group in which OCD occurs following apparent causal events such as streptococcal infections, brain injury, or atypical neuroleptic treatment; and (ii) a genomically based group in which OCD is related to chromosomal anomalies or specific genes. Considering the status of current research, the concept of OCD and OCD-related spectrum conditions seems fluid in 2010, and in need of ongoing reappraisal.

    Compulsive buying (CB) is currently classified as an impulse control disorder (ICD) not otherwise classified. Compulsive buying prevalence is estimated at around 5% of the general population. There is controversy about whether CB should be classified as an ICD, a subsyndromal bipolar disorder (BD), or an obsessive-compulsive disorder (OCD) akin to a hoarding syndrome. To further investigate the appropriate classification of CB, we compared patients with CB, BD, and OCD for impulsivity, affective instability, hoarding, and other OCD symptoms. Eighty outpatients (24 CB, 21 BD, and 35 OCD) who were neither manic nor hypomanic were asked to fill out self-report questionnaires. Compulsive buying patients scored significantly higher on all impulsivity measures and on acquisition but not on the hoarding subdimensions of clutter and "difficulty discarding." Patients with BD scored higher on the mania dimension from the Structured Clinical Interview for Mood Spectrum scale. Patients with OCD scored higher on obsessive-compulsive symptoms and, particularly, higher on the contamination/washing and checking dimensions from the Padua Inventory; however, they did not score higher on any hoarding dimension. A discriminant model built with these variables correctly classified patients with CB (79%), BD (71%), and OCD (77%). Patients with CB came out as impulsive acquirers, resembling ICD- rather than BD- or OCD-related disorders. Manic symptoms were distinctive of patients with BD. Hoarding symptoms other than acquisition were not particularly associated with any diagnostic group. Copyright © 2012 Elsevier Inc. All rights reserved.

    In DSM-III, DSM-III-R, and DSM-IV, obsessive-compulsive disorder (OCD) was classified as an anxiety disorder. In ICD-10, OCD is classified separately from the anxiety disorders, although within the same larger category as anxiety disorders (as one of the "neurotic, stress-related, and somatoform disorders"). Ongoing advances in our understanding of OCD and other anxiety disorders have raised the question of whether OCD should continue to be classified with the anxiety disorders in DSM-V. This review presents a number of options and preliminary recommendations to be considered for DSM-V. Evidence is reviewed for retaining OCD in the category of anxiety disorders, and for moving OCD to a separate category of obsessive-compulsive (OC)-spectrum disorders, if such a category is included in DSM-V. Our preliminary recommendation is that OCD be retained in the category of anxiety disorders but that this category also includes OC-spectrum disorders along with OCD. If this change is made, the name of this category should be changed to reflect this proposed change. (c) 2010 Wiley-Liss, Inc.

    There are ongoing uncertainties in the relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD). This study aimed to test the proposition that OCPD may be a marker of severity of OCD by comparing groups of OCD individuals with and without OCPD on a number of variables. A total of 148 adults with a principal diagnosis of OCD were administered the Mini International Neuropsychiatric Interview, Yale-Brown Obsessive-Compulsive Scale, Sheehan Disability Scale, Vancouver Obsessional Compulsive Inventory and Symptom Checklist 90-Revised. Participants with a DSM-IV diagnosis of OCPD were compared with those without OCPD. Some 70 (47.3%) participants were diagnosed with OCPD. The groups of participants with and without OCPD did not differ significantly with respect to any of the demographic variables, clinician-rated severity of OCD, levels of disability and mean age of onset of OCD. All self-rated OCD symptom dimensions except for contamination and checking were significantly more prominent in participants with OCPD, as were all self-rated dimensions of psychopathology. Participants with OCPD had significantly more frequent hoarding compulsions and obsessions involving a need to collect and keep objects. Of Axis I disorders, only panic disorder was significantly more frequent in participants with OCPD than in those without OCPD. A high frequency of OCPD among individuals with OCD suggests a strong, although not necessarily a unique, relationship between the two conditions. This finding may also be a consequence of the blurring of the boundary between OCD and OCPD by postulating that hoarding and hoarding-like behaviours characterise both disorders. Results of this study do not support the notion that OCD with OCPD is a marker of clinician-rated severity of OCD. However, individuals with OCPD had more prominent OCD symptoms, they were more distressed and exhibited various other psychopathological phenomena more intensely

    The relationship between Obsessive Compulsive Disorder (OCD) and Obsessive Compulsive Personality Disorder (OCPD) has been the subject of interest for some time due to the historical assumption that OCPD causes OCD. This study systematically examined the association between OCD and OCPD in terms of prevalence and clinical presentation. The specificity of the association between OCD and OCPD was investigated relative to another axis I anxiety disorder (Panic disorder). Data for this study were drawn from measures taken at initial assessment at a specialist treatment centre for anxiety disorders. Of the 359 participants included in this study, 189 had a principal diagnosis of OCD, while 170 had a principal diagnosis of Panic disorder. Measures included SCID I and II interview modules and self-report measures of anxiety, depression, and OCD syptomatology. Significantly elevated rates of OCPD were found in OCD relative to Panic disorder. Regardless of axis I disorder, individuals with comorbid OCPD reported more severe depression relative to those without. Participants with both OCD and OCPD had greater self-reported OCD symptom severity, doubting, ordering, and hoarding symptoms at assessment relative to those without OCPD. Participants with OCD and comorbid OCPD also reported significantly higher levels of alcohol consumption. There appears to be a significant and specific association between OCD and OCPD. Co-occurring OCD and OCPD is associated with greater severity of impairment in terms of certain OCD symptoms. The significant and specific association between OCD and OCPD suggests that OCPD occurs more frequently with OCD than previously suggested. A comorbid OCPD diagnosis is associated with a greater degree of depression, regardless of axis I disorder, either OCD or Panic disorder. This is an important consideration, as depression can interfere with therapeutic progress (Foa, 1979). Participants with OCD and OCPD had greater self-reported OCD severity, along

    This study was designed to assess the phenomenology, comorbidities, correlation with depressive disorders, and gender differences in obsessive-compulsive disorder (OCD) in Taiwan. Two hundred outpatients who fulfilled the diagnostic criteria of OCD according to DSM-IV were included. Patient characteristics, age at onset, symptom profile, and Axis I comorbidity were recorded. Gender differences, age at onset, and comorbidity of depressive disorders among different subtypes of OCD were compared. The most common obsession was contamination, followed by pathological doubt, and need for symmetry. The most common compulsion was checking, followed by washing, and orderliness compulsions. More men than women presented with the obsession of need for symmetry. Eighty-three (41.5%) subjects had comorbid depressive disorders. Women had more major depressive disorder. Patients with somatic obsessions were more likely to have major depressive disorder. Most clinical characteristics of OCD in Taiwan were similar to that of previous studies in other countries.

    Significant advances have been made in characterizing the phenomenology and psychobiology of obsessive-compulsive disorder (OCD) in recent years. In many ways, such advances suggest a conceptualization of OCD as a relatively homogeneous neuropsychiatric entity, underpinned by particular mechanisms that manifest in universal symptoms. Nevertheless, some data have pointed to the heterogeneity of this disorder. A computerized literature search (MEDLINE: 1964-2001) was used to collect studies addressing the heterogeneity of OCD. In addition, reviews of the phenomenology, psychobiology, family studies, and treatment of OCD were examined in an attempt to collate data addressing this issue. There is a growing consensus that some subtypes of OCD are valid and provide a useful means of integrating data on its symptomatology, neurobiology, and treatment response; for example, OCD with comorbid tics is characterized by earlier onset, a particular range of OCD symptoms, and worse response to selective serotonin reuptake inhibitors. The heterogeneity of OCD has important clinical and research implications.

    Resolving the entangled nosological dilemma of whether obsessive-compulsive disorder (OCD) with and without schizophrenia (schizo-OCD and OCD, respectively) are two independent entities or whether schizo-OCD is a combined product of its parent disorders. Studying motor activity in OCD and in schizo-OCD patients. Performance of the patients was compared with the performance of the same motor task by a matching control individual. Behavior in both schizo-OCD and OCD patients differed from controls in the excessive repetition and addition of acts, thus validating an identical OC facet. However, there was a significant difference in spatial behavior. Schizo-OCD patients traveled over a greater area with less focused activity as typical to schizophrenia patients and in contrast to OCD patients, who were more focused and traveled less in a confined area. While schizo-OCD and OCD patients share most of the OC ritualistic attributes, they differ in the greater spread of activity in schizo-OCD, which is related to schizophrenia disorder. It is suggested that the finding on difference in spatial behavior is a reflection of the mental differences between OCD and schizophrenia. In other words, this could be an overt and observable manifestation of the mental state, and therefore may facilitate the nosology of OC spectrum disorders and OCD. It seems as if both the OCD patients' focus on specific thoughts, and the contrasting wandering thoughts of schizophrenia patients, are reflected in the focused activity of the former and wandering from one place to the next of the latter.

    Obsessive-compulsive disorder (OCD) is frequently associated with mood disorders. However, to date, the co-occurrence of OCD with seasonal affective disorder (SAD) has not been investigated. We have aimed to estimate the prevalence of seasonal mood changes in patients with OCD and explore the contribution of seasonality in mood to the severity of OCD. The Seasonal Pattern Assessment Questionnaire (SPAQ), the Yale-Brown Obsession and Compulsion Scale (Y-BOCS), the Hamilton Depression Rating Scale-17 Items (HDRS-17), and the Beck Anxiety Inventory (BAI) were administered to patients with OCD (n=104) and controls (n=125). The degree of seasonality was measured by the Global Seasonality Score (GSS) calculated from the SPAQ. SAD and subsyndromal seasonal affective disorder (S-SAD) were significantly more prevalent in patients with OCD (53%, n=55) than controls (25%, n=31). When patients were assessed in the season in which SAD occurs, depression and compulsions (but not obsessions, OCD or anxiety) were more severe than those assessed in a season during which SAD does not occur. SAD frequently co-occurs with OCD and, given this co-occurrence, depression symptoms in some patients with OCD might be expected to vary on a seasonal basis. Copyright © 2016 Elsevier Ireland Ltd.

    The retrospective and subjective nature of clinical interviews is an important shortcoming of current psychiatric diagnosis. Consequently, there is a clear need for objective and standardized tools. Virtual reality (VR) can be used to achieve controlled symptom provocation, which allows direct assessment for the clinician. We developed a video VR game to provoke and assess obsessive-compulsive disorder (OCD) symptoms in a standardized and controlled environment. The first objective was to evaluate if the VR game is capable of provoking symptoms in OCD patients as opposed to healthy controls. The second objective was to evaluate the tolerability of the VR game in OCD patients. The VR game was created using a first-person perspective and confronted patients with 15 OCD-specific items, while simultaneously measuring OCD symptoms, including the number of compulsions, anxiety, tension, uncertainty, and urge to control. In this pilot study, eight patients and eight healthy controls performed the VR game. OCD patients performed significantly more compulsions (U = 5, p = 0.003) during the VR game. The anxiety, tension, uncertainty, and urge to control in response to the specific items were also higher for OCD patients, although significance was not yet reached because of the small sample. There were no substantial adverse effects. The results of this pilot study indicate that the VR game is capable of provoking a variety of OCD symptoms in OCD patients, as opposed to healthy controls, and is a potential valuable tool to objectify and standardize an OCD diagnosis.

    The identification of distinct subtypes based on comorbidity offers potential utility in understanding variations in the clinical expression of obsessive-compulsive disorder (OCD). Hence, we examined the hypothesis whether patients with OCD with major depressive disorder (MDD) or anxiety disorder comorbidity would differ from those without in terms of phenomenology. A total of 545 consecutive patients who consulted a specialty OCD clinic during the period 2004 to 2009 at a psychiatric hospital in India formed the sample. They were evaluated with the Yale-Brown Obsessive-Compulsive Scale (YBOCS), the Mini International Neuropsychiatric Interview, and the Clinical Global Impression scale. Among 545 patients, 165 (30%) had current MDD, and 114 (21%) had current anxiety disorder comorbidity. Patients with OCD with MDD were mostly women who had a greater severity of OCD symptoms, more of obsessions (especially religious), greater occurrence of miscellaneous compulsions (need to confess or need to touch), higher suicidal risk, and past suicidal attempts. Patients with OCD with anxiety disorder had an earlier onset of illness that was associated with prior life events, less of compulsions, more of aggressive and hoarding obsessions, pathologic doubts, checking, and cognitive compulsions. Obsessive-compulsive disorder, when comorbid with MDD, is more severe and is associated with higher suicidal risk. On the other hand, anxiety disorder comorbidity seems to influence not so much the morbidity but the phenotypic expression of OCD. Copyright © 2012 Elsevier Inc. All rights reserved.

    Most research on relations between Obsessive-Compulsive Disorder (OCD) and personality addresses only comorbidity rates between OCD and Obsessive-Compulsive Personality Disorder (OCPD). We first investigated empirical OCD-OCPD relations, but then also examined patterns of dimensional traits in OCD patients versus students and general outpatients. Results did not support a specific OCD-OCPD relation and the implications of this conclusion are discussed. Regarding traits, OCD patients shared with other patients elevated negative affectivity and lower positive affectivity. Differences on several lower order dimensions, including lower scores on manipulativeness, mistrust, and disinhibition distinguished the personality profile of OCD patients from others. Also noteworthy was a pattern of very low self-image for OCD patients, as suggested by the combination of low self-esteem and low entitlement scores. Overall, OCD patients showed a more specific pattern of personality pathology than did general outpatients, who were elevated more generally across personality disorders and negative affectivity scales.

    We evaluated whether traumatic events are associated with a distinctive pattern of socio-demographic and clinical features of obsessive-compulsive disorder (OCD). We compared socio-demographic and clinical features of 106 patients developing OCD after post-traumatic stress disorder (PTSD; termed post-traumatic OCD), 41 patients developing OCD before PTSD (pre-traumatic OCD), and 810 OCD patients without any history of PTSD (non-traumatic OCD) using multinomial logistic regression analysis. A later age at onset of OCD, self-mutilation disorder, history of suicide plans, panic disorder with agoraphobia, and compulsive buying disorder were independently related to post-traumatic OCD. In contrast, earlier age at OCD onset, alcohol-related disorders, contamination-washing symptoms, and self-mutilation disorder were all independently associated with pre-traumatic OCD. In addition, patients with post-traumatic OCD without a previous history of obsessive-compulsive symptoms (OCS) showed lower educational levels, greater rates of contamination-washing symptoms, and more severe miscellaneous symptoms as compared to post-traumatic OCD patients with a history of OCS.

    The present study examines the influence of diagnostic comorbidity on the demographic, psychiatric, and functional status of youth with a primary diagnosis of obsessive compulsive disorder (OCD). Two hundred and fifteen children (ages 5-17) referred to a university-based OCD specialty clinic were compared based on DSM-IV diagnostic profile: OCD without comorbid anxiety or externalizing disorder, OCD plus anxiety disorder, and OCD plus externalizing disorder. No age or gender differences were found across groups. Higher OCD severity was found for the OCD + ANX group, while the OCD + EXT group reported greater functional impairment than the other two groups. Lower family cohesion was reported by the OCD + EXT group compared to the OCD group and the OCD + ANX group reported higher family conflict compared to the OCD + EXT group. The OCD + ANX group had significantly lower rates of tic disorders while rates of depressive disorders did not differ among the three groups. The presence of comorbid anxiety and externalizing psychopathology are associated with greater symptom severity and functional and family impairment and underscores the importance of a better understanding of the relationship of OCD characteristics and associated disorders. Results and clinical implications are further discussed.

The purpose of this paper is to provide evidence for the relationship between personality disorders (PDs, obsessive compulsive disorder (OCD, and other anxiety disorders different from OCD (non-OCD symptomatology. Method. The sample consisted of a group of 122 individuals divided into three groups (41 OCD; 40 non-OCD, and 41 controls matched by sex, age, and educational level. All the individuals answered the IPDE questionnaire and were evaluated by means of the SCID-I and SCID-II interviews. Results. Patients with OCD and non-OCD present a higher presence of PD. There was an increase in cluster C diagnoses in both groups, with no statistically significant differences between them. Conclusions. Presenting anxiety disorder seems to cause a specific vulnerability for PD. Most of the PDs that were presented belonged to cluster C. Obsessive Compulsive Personality Disorder (OCPD is the most common among OCD. However, it does not occur more frequently among OCD patients than among other anxious patients, which does not confirm the continuum between obsessive personality and OCD. Implications for categorical and dimensional diagnoses are discussed.

    Background Obsessive–compulsive disorder (OCD) is probably an etiologically heterogeneous condition. Many patients manifest other psychiatric syndromes. This study investigated the relationship between OCD and co-morbid conditions to identify subtypes. Method Seven hundred and six individuals with OCD were assessed in the OCD Collaborative Genetics Study (OCGS). Multi-level latent class analysis was conducted based on the presence of eight co-morbid psychiatric conditions [generalized anxiety disorder (GAD), major depression, panic disorder (PD), separation anxiety disorder (SAD), tics, mania, somatization disorders (Som) and grooming disorders (GrD)]. The relationship of the derived classes to specific clinical characteristics was investigated. Results Two and three classes of OCD syndromes emerge from the analyses. The two-class solution describes lesser and greater co-morbidity classes and the more descriptive three-class solution is characterized by: (1) an OCD simplex class, in which major depressive disorder (MDD) is the most frequent additional disorder; (2) an OCD co-morbid tic-related class, in which tics are prominent and affective syndromes are considerably rarer; and (3) an OCD co-morbid affective-related class in which PD and affective syndromes are highly represented. The OCD co-morbid tic-related class is predominantly male and characterized by high conscientiousness. The OCD co-morbid affective-related class is predominantly female, has a young age at onset, obsessive–compulsive personality disorder (OCPD) features, high scores on the ‘taboo’ factor of OCD symptoms, and low conscientiousness. Conclusions OCD can be classified into three classes based on co-morbidity. Membership within a class is differentially associated with other clinical characteristics. These classes, if replicated, should have important implications for research and clinical endeavors. PMID:19046474

    Bipolar disorder (BD) is considered to be a common comorbid condition in subjects with obsessive-compulsive disorder (OCD), but there is limited literature on the prevalence of BD and its clinical correlates in those with a primary diagnosis of OCD. We studied the prevalence of BD in a sample of consecutively registered outpatients attending a specialty OCD clinic in India over a period of 13 months. One hundred and seventy-one patients with a primary diagnosis of OCD were assessed systematically using structured and semi-structured instruments. The prevalence of lifetime BD in OCD was 4%. The OCD + BD group had an episodic course of OCD and higher rate of lifetime suicide attempts. BD may not be as highly prevalent in OCD as reported in literature. Those with OCD seem to have only a marginally higher risk for developing BD than the general population. A diagnosis of BD seems to have a pathoplastic effect on the course of OCD. Patients with OCD-BD comorbidity have to be specifically assessed for suicide risk.

    Identifying risk factors of psychopathology has been an important research challenge. Prior studies examining the impact of childhood temperament on adult disorder have largely focused on undercontrolled and inhibited presentations, with little study of overcontrolled traits such as obsessive-compulsive personality traits (OCPTs). We compared rates of childhood OCPTs in adults with OCD (without OCPD) (n = 28) to adults with OCPD (without OCD) (n = 27), adults with both OCD and OCPD (n = 28), and healthy controls (HC) (n= 28), using the Childhood Retrospective Perfectionism Questionnaire, a validated measure of perfectionism, inflexibility, and drive for order. Adults with OCPD (both with and without comorbid OCD) reported higher rates of all three childhood OCPTs relative to HC. Individuals with OCD (without OCPD) reported higher rates of inflexibility and drive for order relative to HC, suggesting that these traits may presage the development of OCD, independent of OCPD. Childhood OCPTs were associated with particular OCD symptom dimensions in adulthood (contamination/cleaning, doubt/checking, and symmetry/ordering), independent of OCD onset age and OCPD diagnosis. Longitudinal prospective studies evaluating OCPTs in children are needed to better understand the progression of these traits from childhood to adulthood and their ability to predict future psychopathology.

    The evidence regarding whether co-morbid obsessive compulsive personality disorder (OCPD) is associated with treatment outcomes in obsessive compulsive disorder (OCD) is mixed, with some research indicating that OCPD is associated with poorer response, and some showing that it is associated with improved response. We sought to explore the role of OCPD diagnosis and the personality domain of conscientiousness on treatment outcomes for exposure and response prevention for OCD. The impact of co-morbid OCPD and conscientiousness on treatment outcomes was examined in a clinical sample of 46 participants with OCD. OCPD diagnosis and scores on conscientiousness were not associated with poorer post-treatment OCD severity, as indexed by Yale-Brown Obsessive Compulsive Scale (YBOCS) scores, although the relative sample size of OCPD was small and thus generalizability is limited. This study found no evidence that OCPD or conscientiousness were associated with treatment outcomes for OCD. Further research with larger clinical samples is required.

    Comorbidity of certain obsessive-compulsive spectrum disorders (OCSDs; such as Tourette's disorder) in obsessive-compulsive disorder (OCD) may serve to define important OCD subtypes characterized by differing phenomenology and neurobiological mechanisms. Comorbidity of the putative OCSDs in OCD has, however, not often been systematically investigated. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition , Axis I Disorders-Patient Version as well as a Structured Clinical Interview for Putative OCSDs (SCID-OCSD) were administered to 210 adult patients with OCD (N = 210, 102 men and 108 women; mean age, 35.7 +/- 13.3). A subset of Caucasian subjects (with OCD, n = 171; control subjects, n = 168), including subjects from the genetically homogeneous Afrikaner population (with OCD, n = 77; control subjects, n = 144), was genotyped for polymorphisms in genes involved in monoamine function. Because the items of the SCID-OCSD are binary (present/absent), a cluster analysis (Ward's method) using the items of SCID-OCSD was conducted. The association of identified clusters with demographic variables (age, gender), clinical variables (age of onset, obsessive-compulsive symptom severity and dimensions, level of insight, temperament/character, treatment response), and monoaminergic genotypes was examined. Cluster analysis of the OCSDs in our sample of patients with OCD identified 3 separate clusters at a 1.1 linkage distance level. The 3 clusters were named as follows: (1) "reward deficiency" (including trichotillomania, Tourette's disorder, pathological gambling, and hypersexual disorder), (2) "impulsivity" (including compulsive shopping, kleptomania, eating disorders, self-injury, and intermittent explosive disorder), and (3) "somatic" (including body dysmorphic disorder and hypochondriasis). Several significant associations were found between cluster scores and other variables; for example, cluster I scores were associated

    2008-09-01

    As a result of clinical, epidemiological, neuroimaging, and therapy studies that took place in the late 1980s, obsessive-compulsive disorder (OCD) has been well-characterized in the field of anxiety disorders. Other disorders attracted attention for their similarities to OCD, and were located in the orbit of the disorder. OCD has become known as the "primary domain" of a scientific "metaphor" comprising the putative cluster of OCD-related disorders (OCRDs). It is a "paradigm" with which to explore basal ganglia dysfunction. The OCRDs share common phenomenology, comorbidities, lifetime course, demographics, possible genetics, and frontostriatal dysfunction (particularly caudate hyperactivity.) The adoption of this metaphor analogy has proven useful. However, 15 years since its emergence, the spectrum of obsessive-compulsive disorders remains controversial. Questions under debate include whether OCD is a unitary or split condition, whether it is an anxiety disorder, and whether there exists only one spectrum or several possible spectrums. Further work is needed to clarify obsessive-compulsive symptoms, subtypes, and endophenotypes. There is need to integrate existing databases, better define associated symptom domains, and create a more comprehensive endophenotyping protocol for OCRDs. There is also a need to integrate biological and psychological perspectives, concepts, and data to drive this evolution. By increasing research in this field, the OCD spectrum may evolve from a fragmented level of conceptualization as a "metaphor" to one that is more comprehensive and structured.

    This review evaluates the evidence reporting an association of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD) with Tourette's syndrome or disorder (TS). Published reports in the literature describing a relationship between OCS-OCD and TS provided the data for the review. The methodological adequacy of the studies are discussed and rated on five criteria: adequacy of the experimental sample, presence and adequacy of the control sample, whether tics are defined as OCS-OCD, whether blind procedures are used to diagnose OCS-OCD in subjects and controls, and evidence for the reliability and validity of OCS-OCD measures. Although there are considerable clinical indications suggesting an association of OCS-OCD with TS and chronic motor tic disorder (CMT), and a possible overlap between OSC-OCD and TS, our evaluation of the evidence does not provide adequate support for an association between these disorders. To meaningfully evaluate the possible relationship between OCS-OCD and TS requires development of specific criteria for classification of OCS-OCD-TS symptoms, use of adequate experimental and control samples, blind evaluation, reliable and valid measures of OCS-OCD-TS, and appropriate statistical analysis. If such studies are performed, it is possible that the strong relationship reported between OCS-OCD and TS is more likely to be artifact than fact, and recent bandwagon effect rather than the latest breakthrough.

    This study introduces a laboratory model of compulsive behavior based on persistence in the context of rewarded spatial alternation. Rats were screened for spontaneous persistence during T-maze reinforced alternation. Experiment 1: One high and one low spontaneous persistence group (n = 8) received 20 injections of fluoxetine, a matched pair saline, both followed by 4 days of meta-chlorophenylpiperazine (mCPP) challenge. Experiment 2: Five matched groups of rats (n = 9) received pretreatment (20 injections) with fluoxetine, mCPP, desipramine, diazepam or saline, followed by 4 days of mCPP challenge (fluoxetine in mCPP group). After washout, animals received 2 days of naratriptan, followed by another 2-day mCPP challenge. In both experiments mCPP significantly increased persistence in saline controls. Fluoxetine also acutely increased persistence scores: after a gradual return to baseline, these scores showed tolerance to mCPP. Experiment 1: This pattern was significant in high but not low initial persistence groups. Experiment 2: Fluoxetine and mCPP showed cross-tolerance. Neither desipramine nor diazepam protected against mCPP challenge. Persistence scores returned to baseline during washout and naratriptan and were thereafter increased by another mCPP challenge in all but the fluoxetine and mCPP groups, suggesting 5-HT2C receptor mediation. This model is based on spontaneous persistence behavior showing pharmacological responses concordant with those of compulsive symptomatology.

    2011-12-01

    Full Text Available Obsessive-compulsive disorder (OCD is a neuropsychiatric disorder affecting approximately 1-3% of the population. OCD is probably an etiologically heterogeneous condition. Individuals with OCD frequently have additional psychiatric disorders concomitantly or at some time during their lifetime. Recently, some authors proposed an OCD sub-classification based on co-morbidity. An important issue in assessing comorbidity is the fact that the non-response to treatment often involves the presence of comorbid conditions. Non-responsive patients are more likely to meet criteria for comorbid axis I or axis II disorders and the presence of a specific comorbid condition could be a distinguishing feature in OCD, with influence on the treatment adequacy and outcome.

    Although traditionally obsessive-compulsive disorder (OCD) and impulse control disorders (ICD) have represented opposing ends of a continuum, recent research has demonstrated a frequent co-occurrence of impulsive and compulsive behaviours, which may contribute to a worse clinical picture of some psychiatric disorders. We hypothesize that individuals with 'impulsive' OCD as characterized by poor insight, low resistance, and reduced control towards their compulsions will have a deteriorative course, greater severity of hoarding and/or symmetry/ordering symptoms, and comorbid ICD and/or substance use disorders (SUD). The sample consisted of 869 individuals with a minimum score of 16 on the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Of these, 65 had poor insight, low resistance, and reduced control towards compulsions ('poor IRC') and 444 had preserved insight, greater resistance and better control over compulsions ('good IRC'). These two groups were compared on a number of clinical and demographic variables. Individuals with poor IRC were significantly more likely to have a deteriorative course (p disorder (p = 0.026), trichotillomania (p = 0.014) and compulsive buying (p = 0.040). Regression analysis revealed that duration of obsessions (p = 0.037) and hoarding severity (p = 0.005) were significant predictors of poor IRC. In the absence of specific measures for impulsivity in OCD, the study highlights the utility of simple measures such as insight, resistance and control over compulsions as a phenotypic marker of a subgroup of OCD with impulsive features demonstrating poor clinical outcome.

    Full Text Available Objectives: To estimate the prevalence of obsessive-compulsive symptoms (OCS and disorder (OCD among adolescents and to describe OCD characteristics according to gender. Methods: Participants were selected by cluster sampling at seven high-schools in southern Brazil. In the first stage, 2,323 students were screened for OCS; in the second stage, adolescents scoring ≥ 21 on the OCI-R scale were individually interviewed. OCD diagnosis was established using a semi-structured interview (Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version - K-SADS-PL. Results: The past-month estimated prevalence of OCS was 18.3%, and the point estimated prevalence of OCD, 3.3%. Girls showed higher scores (OCS: 24.8 vs. 14.4%; OCD: 4.9 vs. 1.4%; p < 0.001. Only 9.3% of OCD adolescents had been diagnosed and 6.7% received treatment. The most frequent/severe DY-BOCS dimensions were miscellaneous (86.7%; mean score 6.3±3.8 and symmetry (85.3%; 5.9±3.8. Female OCD adolescents predominantly showed depression (p = 0.032, and male adolescents, tic disorders (p = 0.006. Conclusions: OCD is underdiagnosed in adolescents, and few are treated. Future studies should investigate the relationship between OCS and the onset of OCD.

    As opposed to other psychiatric populations, subjects with obsessive-compulsive disorder (OCD) smoke less than the general population. The present study aims at further investigating the relationship between smoking in OCD subjects and personality traits. Sixty-four subjects with OCD were interviewed concerning their smoking habits. Personality traits were evaluated using the Karolinska Scales of Personality, and specific obsessive-compulsive personality traits were elicited through self-report questionnaires. Non-smokers were more easily fatigued, more inclined to worry, more remorseful, less self-confident, less impulsive and became uneasy more frequently when urged to speed up, than smokers with OCD. Additionally, non-smokers fulfilled significantly more obsessive-compulsive personality disorder criteria as compared to the smokers (P < 0.001). We propose a clinical subtype of OCD related to non-smoking, psychasthenia, anxiety, and pronounced obsessive-compulsive personality disorder traits.

    This study examines the obsessive-compulsive disorder (OCD) with normal and poor insight of illness and it detects the presence of autistic traits. The aim is to establish the relationship between OCD and Autistic Spectrum Disorder (ASD): comorbidity or subtype of OCD? The sample consists of 48 adolescents (aged 12-18) with a clinical diagnosis of OCD (according DSM-IV-TR). After administering the Children's Yale Brown Obsessive-Compulsive Scale (CYBOCS) and the Brown Assessement Beliefs Scale (BABS), the sample is divided into two groups according to insight of illness. Autism Diagnostic Observation Schedule (ADOS) and Social Communication Questionnaire (SCQ) were used to assist in the ASD diagnosis; Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II) was administered to assess personality disorders. 47% of subjects presents poor insight and 27% are included within the diagnostic criteria for autistic spectrum disorder. Poor insight in obsessive-compulsive symptoms is significantly associated with the presence of autistic traits. There is also a significant association between cluster hoarding and poor insight. This study suggests the existence of an obsessive autistic atypical subtype, where the compulsive dimension of repetitive behaviours vanishes in an autistic dimension with stereotyped manifestations. Further research should be conducted to better understand this obsessive autistic atypical subtype and to put it in the obsessive-compulsive spectrum in adolescence.

    Tourette syndrome/chronic tic disorder (TS/CT) and obsessive-compulsive disorder (OCD) overlap in their phenomenological features and often co-occur in affected individuals and families. Understanding how these disorders cluster in families provides important clinical information and is an important step in understanding the causes of these disorders. To determine familial recurrence for TS/CT and OCD using a national epidemiologic sample. We performed a population-based study of national health registries in Denmark, including all individuals (n = 1 741 271) born in Denmark from January 1, 1980, through December 31, 2007, and followed up through December 31, 2013. We identified those with TS/CT and/or OCD. The prevalence of TS/CT and OCD and relative recurrence risk (RRR) for TS/CT or OCD among individuals with an oldest sibling or a parent diagnosed as having TS/CT or OCD compared with individuals without an affected oldest sibling or an affected parent. In this sample, 5596 individuals were diagnosed as having TS/CT; 6191, OCD; and 412, both disorders. The overall cohort prevalence of TS/CT was 0.42% (95% CI, 0.41%-0.43%) and of OCD, 0.84% (95% CI, 0.81%-0.87%). The mean sibling recurrence risk for TS/CT across all birth years was 9.88% (95% CI, 8.02%-12.16%) and for OCD, 4.01% (95% CI, 2.78%-5.76%). The sibling RRR for TS/CT was 18.63 (95% CI, 15.34-22.63). In contrast, the sibling RRR for OCD was 4.89 (95% CI, 3.45-6.93). The parent-offspring RRR for TS/CT was 61.02 (95% CI, 44.43-83.82), whereas the parent-offspring RRR for OCD was 6.25 (95% CI, 4.82-8.11). The sibling and parent-offspring cross-disorder risks were also significant, ranging from 3.20 (95% CI, 2.22-4.62) to 10.27 (95% CI, 5.17-20.39). Tourette syndrome/CT and OCD cluster in families. The familial aggregation of TS/CT is profound and substantially higher than the familial aggregation for OCD. The recurrence risk estimates provide an important clinical framework for identifying

    Full Text Available Abstract Background Similarities between obsessive-compulsive disorder (OCD and trichotillomania (TTM have been widely recognized. Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions. Methods Two hundred and seventy eight OCD patients (n = 278: 148 male; 130 female and 54 TTM patients (n = 54; 5 male; 49 female of all ages were interviewed. Female patients were compared on select demographic and clinical variables, including comorbid axis I and II disorders, and temperament/character profiles. Results OCD patients reported significantly more lifetime disability, but fewer TTM patients reported response to treatment. OCD patients reported higher comorbidity, more harm avoidance and less novelty seeking, more maladaptive beliefs, and more sexual abuse. OCD and TTM symptoms were equally likely to worsen during menstruation, but OCD onset or worsening was more likely associated with pregnancy/puerperium. Conclusions These findings support previous work demonstrating significant differences between OCD and TTM. The classification of TTM as an impulse control disorder is also problematic, and TTM may have more in common with conditions characterized by stereotypical self-injurious symptoms, such as skin-picking. Differences between OCD and TTM may reflect differences in underlying psychobiology, and may necessitate contrasting treatment approaches.

    Background Similarities between obsessive-compulsive disorder (OCD) and trichotillomania (TTM) have been widely recognized. Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions. Methods Two hundred and seventy eight OCD patients (n = 278: 148 male; 130 female) and 54 TTM patients (n = 54; 5 male; 49 female) of all ages were interviewed. Female patients were compared on select demographic and clinical variables, including comorbid axis I and II disorders, and temperament/character profiles. Results OCD patients reported significantly more lifetime disability, but fewer TTM patients reported response to treatment. OCD patients reported higher comorbidity, more harm avoidance and less novelty seeking, more maladaptive beliefs, and more sexual abuse. OCD and TTM symptoms were equally likely to worsen during menstruation, but OCD onset or worsening was more likely associated with pregnancy/puerperium. Conclusions These findings support previous work demonstrating significant differences between OCD and TTM. The classification of TTM as an impulse control disorder is also problematic, and TTM may have more in common with conditions characterized by stereotypical self-injurious symptoms, such as skin-picking.

    The literature on subclinical autism spectrum (ASD) symptoms in pediatric obsessive-compulsive disorder (OCD) is scarce, and it remains unclear whether ASD symptoms are related to OCD severity. The aims of the present study were to assess the prevalence of ASD symptoms and age and sex differences in children and adolescents with OCD, and to explore the relation between ASD symptoms and OCD severity. This is the largest study of ASD symptoms in an OCD population to date, and the first directly aimed at elucidating sex and age differences in this matter. The study used baseline data from the Nordic Long-term OCD Treatment Study in which parents of 257 children and adolescents with OCD aged 7-17 completed the Autism Spectrum Screening Questionnaire. OCD severity was assessed with the Children's Yale-Brown Obsessive Compulsive Scale. Pediatric OCD patients were found to exhibit elevated rates of ASD symptoms compared to a norm group of school-age children. ASD symptoms were concentrated in a subgroup with a prevalence of 10-17 %. This subgroup was characterized by a male preponderance with a sex ratio of approximately 2.6:1, while children versus adolescents with OCD exhibited similar rates. Autism-specific social and communication difficulties were not related to OCD severity, while restricted repetitive behavior was positively related to OCD severity. The results indicate that clinicians need to be aware of ASD symptoms in children and adolescents with OCD since one out of ten exhibits such symptoms at a clinical sub-threshold.

  4. Goal-directed learning and obsessive–compulsive disorder

    2014-01-01

    Obsessive–compulsive disorder (OCD) has become a paradigmatic case of goal-directed dysfunction in psychiatry. In this article, we review the neurobiological evidence, historical and recent, that originally led to this supposition and continues to support a habit hypothesis of OCD. We will then discuss a number of recent studies that have directly tested this hypothesis, using behavioural experiments in patient populations. Based on this research evidence, which suggests that rather than goal-directed avoidance behaviours, compulsions in OCD may derive from manifestations of excessive habit formation, we present the details of a novel account of the functional relationship between these habits and the full symptom profile of the disorder. Borrowing from a cognitive dissonance framework, we propose that the irrational threat beliefs (obsessions) characteristic of OCD may be a consequence, rather than an instigator, of compulsive behaviour in these patients. This lays the foundation for a potential shift in both clinical and neuropsychological conceptualization of OCD and related disorders. This model may also prove relevant to other putative disorders of compulsivity, such as substance dependence, where the experience of ‘wanting’ drugs may be better understood as post hoc rationalizations of otherwise goal-insensitive, stimulus-driven behaviour.

    Obsessive-compulsive disorder (OCD) is a chronic illness that can cause marked distress and disability. It is a complex disorder with a variety of manifestations and symptom dimensions, some of which are underrecognized. Early recognition and treatment with OCD-specific therapies may improve outcomes, but there is often a delay in diagnosis. Patients can experience significant improvement with treatment, and some may achieve remission. Recommended first-line therapies are cognitive behavior therapy, specifically exposure and response prevention, and/or a selective serotonin reuptake inhibitor (SSRI). Patients with OCD require higher SSRI dosages than for other indications, and the treatment response time is typically longer. When effective, long-term treatment with an SSRI is a reasonable option to prevent relapse. Patients with severe symptoms or lack of response to first-line therapies should be referred to a psychiatrist. There are a variety of options for treatment-resistant OCD, including clomipramine or augmenting an SSRI with an atypical antipsychotic. Patients with OCD should be closely monitored for psychiatric comorbidities and suicidal ideation.

    2015-06-01

    Sleep problems are not a core feature of obsessive-compulsive disorder (OCD), but emerging empirical data indicate some form of sleep disruption to be highly common. Available research in both adult and child patients is limited in several important ways, including the use of subjective reports (particularly in children), high rates of comorbid depression, and concurrent use of psychotropic medication. The presence of sleep disruption in OCD patients may compound severity and impairment of the disorder. More research is needed to fully understand the nature and consequences of sleep-wake disruption in children with OCD. Copyright © 2015 Elsevier Inc. All rights reserved.

    Previous research has shown that among the various subtypes of obsessive-compulsive disorder (OCD), adults (e.g. Frost, Krause & Steketee, 1996) and older children and adolescents (Bloch et al., 2009; Storch et al., 2007) with problematic hoarding have distinct features and a poor treatment prognosis. However, there is limited information on the phenomenology and prevalence of hoarding behaviors in young children. The present study characterizes children ages 10 and under who present with OCD...

    2003-08-01

    The cross-sectional comorbidity of child and adolescent inpatients with obsessive-compulsive disorder (OCD) was assessed. The hospital records of all inpatients treated for OCD since 1976 (31 girls, 46 boys) were compared with data from a prospective epidemiological longitudinal study (90 girls, 84 boys) in two age cohorts ( or = 15 years) with regard to comorbid psychiatric diagnoses. Additionally, psychiatric Axis I diagnoses of patients with a supplementary diagnosis of compulsive symptoms (n = 45) were descriptively assessed in the client population. In the subgroup of OCD patients tic disorders. OCD girls > or = 15 years showed a tendency toward more frequent comorbid affective disorders and a significant result regarding concurrent eating disorders. Eighteen of 27 female patients with supplementary compulsive symptoms requiring clinical intervention had an Axis I diagnosis of eating disorder. Due to different criteria of classification, diverging definitions of comorbidity and different age cohorts and samples, studies on comorbidity in OCD patients are difficult to compare. The frequency of comorbid psychiatric disorders may be over-estimated if the general prevalence of psychiatric disorders in terms of gender and age is not taken into account.

    Full Text Available Objective. The purpose of this study was to compare the prevalence of comorbid eating disorders in Obsessive-Compulsive Disorder (OCD and other common anxiety disorders. Method. 179 patients from the same geographical area with a diagnosis of OCD or an anxiety disorder were divided into two groups based on their primary diagnosis. The prevalence of a comorbid eating disorder was calculated in both groups. Results. There was no statistically significant difference in the prevalence of comorbid eating disorders between the OCD and other anxiety disorders group. Conclusions. These results suggest that the prevalence of comorbid eating disorders does not differ in anxiety disorders when compared with OCD. However, in both groups, it remains statistically higher than that of the general population.

    2014-01-01

    Compulsive buying disorder (CBD) refers to the chronic purchasing of unneeded or unwanted items, causing significant negative consequences. There are no established criteria for CBD, and operational definitions have relied on similarities with OCD, substance use disorders, and impulse control disorders. Compulsive buying disorder is common, affecting 5.8% of the general population, according to one study. Typically, CBD has early onset, frequent comorbidities, and a chronic course. The etiology of CBD is unknown, with biological, psychological and sociocultural factors proposed as likely contributors. Treatment data are limited and suggest addressing comorbid conditions and considering cognitive behavioral therapy, financial and family counseling, selective serotonin reuptake inhibitors, and naltrexone, among other possible interventions, to target CBD. Beyond treatment, educational, legislative and family-based public policy initiatives can likely help individuals with CBD and other excessive spenders.

    We examined whether the patients with Bipolar Disorder (BD) and Obsessive-Compulsive Disorder (OCD) comorbidity may represent a distinct form of BD. The subjects diagnosed with BD (n=48), OCD (n=61), and BD with OCD (n=32) were compared in terms of several socio-demographic and clinical characteristics. Previous history of suicidal attempts was more likely to be higher in BD-OCD group compared to the other two groups. A more episodic course of OCD, higher rates of rapid cycling, and the seasonality were found in BD-OCD patients. The frequency of bipolar II and NOS subtypes was more prevalent in patients with BD-OCD than in OCD patients. The first diagnosed illness was BD in the majority of BD-OCD cases. It was found that first affective episode was major depression in half of BD-OCD patients. Age at onset of BD was found to be earlier in BD-OCD group compared to pure BD patients. Bipolarity may not have a specific effect on the phenomenology of OC symptoms. The episodic course of OCD, seasonality, rapid cycling, earlier onset of BD, and impulsivity in BD-OCD patients may be indicative for a distinct form of BD. Copyright © 2015 Elsevier Ireland Ltd.

    While behavioral and psychopharmacological approaches are the most effective interventions for treating obsessive-compulsive disorder (OCD), psychodynamically oriented play therapy can enhance the treatment of children with this disorder. Play therapy techniques are useful in addressing treatment resistance, feelings of shame around OCD symptoms, negative self-concept, and issues of psychosocial adjustment. A case study illustrates this integrated approach to treatment.

    Obsessive-compulsive disorder (OCD) in childhood and adolescence is an impairing condition, associated with a specific set of distressing symptoms incorporating repetitive, intrusive thoughts (obsessions) and distressing, time-consuming rituals (compulsions). This review considers current knowledge of causes and mechanisms underlying OCD, as well as assessment and treatment. Issues relating to differential diagnosis are summarised, including the challenges of distinguishing OCD from autism spectrum disorders and tic disorders in youth. The recommended treatments, namely cognitive behaviour therapy and serotonin reuptake inhibiting/selective serotonin reuptake inhibitor medications, are outlined along with the existing evidence-based and factors associated with treatment resistance. Finally, novel clinical developments that are emerging in the field and future directions for research are discussed. Published by the BMJ Publishing Group Limited.

    Little is known about personality disorders and normal personality dimensions in relatives of patients with obsessive-compulsive disorder (OCD). To determine whether specific personality characteristics are part of a familial spectrum of OCD. Clinicians evaluated personality disorders in 72 OCD case and 72 control probands and 198 case and 207 control first-degree relatives. The selfcompleted Revised NEO Personality Inventory was used for assessment of normal personality dimensions. The prevalence of personality disorders and scores on normal personality dimensions were compared between case and control probands and between case and control relatives. Case probands and case relatives had a high prevalence of obsessive-compulsive personality disorder (OCPD) and high neuroticism scores. Neuroticism was associated with OCPD in case but not control relatives. Neuroticism and OCPD may share a common familial aetiology with OCD.

    2011-01-01

    Background It seems that the core neural regions and cognitive processes implicated in obsessive-compulsive disorder (OCD) pathophysiology may overlap with those involved in humor appreciation. However, to date, there have been no studies that have explored humor appreciation in OCD. The purpose of the present work was to investigate humor appreciation in a group of patients with OCD. Methods We examined 25 patients with OCD and 25 healthy controls, matched by age, education, and gender. We administered Penn's Humor Appreciation Test (PHAT), a computerized test comprising captionless cartoons by Mordillo. Each set of stimuli consisted of two almost identical drawings, one of which was funny due to the alteration of a detail in the cartoon, whereas the other was not funny. Severity of psychopathology was evaluated with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS). Results No significant effect for group, gender or group × gender interaction was found on the PHAT scores. In OCD patients, humor appreciation was not significantly associated with age of onset, duration of illness, and obsessions, but correlated significantly with compulsions. Conclusions Humor appreciation, based on captionless cartoons in OCD, does not seem to be deficient compared to healthy subjects but may be related to illness characteristics. PMID:22103926

    Error monitoring, cognitive control and motor inhibition control are proposed as cognitive alterations disrupted in obsessive-compulsive disorder (OCD). OCD has also been associated with an increased sensitivity to social evaluations. The effect of a social simulation over electrophysiological indices of cognitive alterations in OCD was examined. A case-control cross-sectional study measuring event-related potentials (ERP) for error monitoring (Error-Related Negativity), cognitive control (N2) and motor control (LRP) was conducted. We analyzed twenty OCD patients and twenty control participants. ERP were recorded during a social game consisting of a visual discrimination task, which was performed in the presence of a simulated superior or an inferior player. Significant social effects (different ERP amplitudes in Superior vs. Inferior player conditions) were found for OCD patients, but not for controls, in all ERP components. Performing the task against a simulated inferior player reduced abnormal ERP responses in OCD to levels observed in controls. The hierarchy-induced ERP effects were accompanied effects over reaction times in OCD patients. Social context modulates signatures of abnormal cognitive functioning in OCD, therefore experiencing a social superiority position impacts over cognitive processes in OCD such as error monitoring mechanisms. These results open the door for the research of new therapeutic choices.

    2018-06-01

    This study examined the hypothesis that participants diagnosed with obsessive-compulsive disorder (OCD) show a selective deficit in inductive reasoning but are equivalent to controls in deductive reasoning. Twenty-five participants with OCD and 25 non-clinical controls made inductive and deductive judgments about a common set of arguments that varied in logical validity and the amount of positive evidence provided (premise sample size). A second inductive reasoning task required participants to make forced-choice decisions and rate the usefulness of diverse evidence or non-diverse evidence for evaluating arguments. No differences in deductive reasoning were found between participants diagnosed with OCD and control participants. Both groups saw that the amount of positive evidence supporting a conclusion was an important guide for evaluating inductive arguments. However, those with OCD showed less sensitivity to premise diversity in inductive reasoning than controls. The findings were similar for both emotionally neutral and OCD-relevant stimuli. The absence of a clinical control group means that it is difficult to know whether the deficit in diversity-based reasoning is specific to those with OCD. People with OCD are impaired in some forms of inductive reasoning (using diverse evidence) but not others (use of sample size). Deductive reasoning appears intact in those with OCD. Difficulties using evidence diversity when reasoning inductively may maintain OCD symptoms through reduced generalization of learned safety information. Copyright © 2017 Elsevier Ltd.

    Paediatric obsessive-compulsive disorder (OCD) and tic disorders (TD) often present together. However, there has been relatively little research on whether comorbid tic disorders influence response to cognitive behaviour therapy (CBT) for OCD. This study aimed to examine the outcomes of CBT for paediatric patients with OCD and a tic disorder compared to a matched group of children with OCD and no tics. Outcomes were compared post-treatment and at 3 or 6 month follow-up. Participants were 29 young people with tic disorders and OCD (OCD + TD) and 29 young people with OCD without tic disorders (OCD-TD) who were matched according to age, gender and baseline OCD symptom severity. All participants received a course of CBT and outcomes were assessed using the Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS). OCD symptoms reduced over the course of CBT to an equivalent extent in the OCD + TD and OCD-TD groups. Response or remission rates did not differ significantly at either post-intervention or follow-up between those with OCD + TD and those with OCD-TD. For both groups, response rates were high - 72% of both groups were classified as responders post-intervention and, at follow-up, 81% of the OCD + TD group and 82% of the OCD no tics group responded. Those with OCD + TD responded in significantly fewer sessions than those with OCD without tics. A number of potential confounding factors were not assessed and therefore could not be controlled for, such as other comorbidities and stability of medication. Paediatric patients with OCD and tic disorders respond equally well to standard CBT for OCD as compared to those with OCD and no tics. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2013-01-01

    Eating disorders and obsessive-compulsive disorder (OCD) commonly co-occur, but there is little data for how to treat these complex cases. To address this gap, we examined the naturalistic outcome of 56 patients with both disorders, who received a multimodal treatment program designed to address both problems simultaneously. A residential treatment program developed a cognitive-behavioral approach for patients with both OCD and an eating disorder by integrating exposure and response prevention (ERP) treatment for OCD with ERP strategies targeting eating pathology. Patients also received a supervised eating plan, medication management, and social support. At admission and discharge, patients completed validated measures of OCD severity (the Yale-Brown Obsessive-Compulsive Scale--Self Report [Y-BOCS-SR]), eating disorder severity (the Eating Disorders Examination-Questionnaire), and depressive severity (the Beck Depression Inventory II [BDI-II]). Body mass index (BMI) was also measured. Paired-sample t-tests examined change on these measures. Between 2006 and 2011, 56 individuals completed all study measures at admission and discharge. Mean length of stay was 57 days (SD = 27). Most (89%) were on psychiatric medications. Significant decreases were observed in OCD severity, eating disorder severity, and depression. Those with bulimia nervosa showed more improvement than those with anorexia nervosa. BMI significantly increased, primarily among those underweight at admission. Simultaneous treatment of OCD and eating disorders using a multimodal approach that emphasizes ERP techniques for both OCD and eating disorders can be an effective treatment strategy for these complex cases.

    2015-01-01

    The core symptoms of obsessive-compulsive personality disorder (OCPD) often lead to interpersonal difficulties. However, little research has explored interpersonal functioning in OCPD. This study examined interpersonal problems, interpersonal sensitivities, empathy, and systemizing, the drive to analyze and derive underlying rules for systems, in a sample of 25 OCPD individuals, 25 individuals with comorbid OCPD and obsessive-compulsive disorder (OCD), and 25 healthy controls. We found that OCPD individuals reported hostile-dominant interpersonal problems and sensitivities with warm-dominant behavior by others, whereas OCPD+OCD individuals reported submissive interpersonal problems and sensitivities with warm-submissive behavior by others. Individuals with OCPD, with and without OCD, reported less empathic perspective taking relative to healthy controls. Finally, we found that OCPD males reported a higher drive to analyze and derive rules for systems than OCPD females. Overall, results suggest that there are interpersonal deficits associated with OCPD and the clinical implications of these deficits are discussed.

    The core symptoms of obsessive-compulsive personality disorder (OCPD) often lead to interpersonal difficulties. However, little research has explored interpersonal functioning in OCPD. The current study examined interpersonal problems, interpersonal sensitivities, empathy, and systemizing, the drive to analyze and derive underlying rules for systems, in a sample of 25 OCPD individuals, 25 individuals with comorbid OCPD and obsessive-compulsive disorder (OCD), and 25 healthy controls. We found that OCPD individuals reported hostile-dominant interpersonal problems and sensitivities with warm-dominant behavior by others while OCPD+OCD individuals reported submissive interpersonal problems and sensitivities with warm-submissive behavior by others. Individuals with OCPD, with and without OCD, reported less empathic perspective taking relative to healthy controls. Finally, we found that OCPD males reported a higher drive to analyze and derive rules for systems than OCPD females. Overall, results suggest that there are interpersonal deficits associated with OCPD and the clinical implications of these deficits are discussed. PMID:25046040

    The social attitudes and interpersonal relationships of patients with obsessive-compulsive disorder (OCD) are subject to a longstanding controversy. Whereas cognitive-behavioural researchers emphasize exaggerated pro-social attitudes in OCD like inflated responsibility and worry for other people (especially significant others), dynamic theories traditionally focus on anti-social attitudes such as latent aggression and hostility. In two recent studies, we gathered support not only for a co-existence of these seemingly opposing attitudes in OCD, but also for a functional connection: inflated responsibility in part appears to serve as a coping strategy (or “defense”) against negative interpersonal feelings. In the present study, we tested a shortened version of the Responsibility and Interpersonal Behaviours and Attitudes Questionnaire (RIBAQ-R). The scale was administered to 34 participants with OCD and 34 healthy controls. The questionnaire concurrently measures pro-social and anti-social interpersonal attitudes across three subscales. In line with our prior studies, patients displayed higher scores on both exaggerated pro-social attitudes (e.g. “I suffer from a strict conscience concerning my relatives”) as well as latent aggression (e.g. “Sometimes I would like to harm strangers on the street“) and suspiciousness/distrust (e.g. “I cannot even trust my own family”). A total of 59% of the patients but only 12% of the healthy controls showed marked interpersonal ambivalence (defined as scores higher than one standard deviation from the mean of the nonclinical controls on both the prosocial and at least one of the two anti-social subscales). The study asserts high interpersonal ambivalence in OCD. Further research is required to pinpoint both the dynamic and causal links between opposing interpersonal styles. Normalization and social competence training may prove beneficial to resolve the apparent problems of patients with OCD regarding anger

    It has been hypothesized that parents of patients with obsessive compulsive disorder exhibit specific traits. 320 consecutive inpatient admissions who met criteria for OCD, depression, and panic disorder checked a list of adjectives to describe their parents. Patients with OCD were 1) less likely to perceive their mothers as disorganized than depressives, 2) more likely to perceive their mothers as overprotective than depressives and 3) less likely to perceive their fathers as demanding than patients with panic.

    Behavioral inhibition is frequently cited as a vulnerability factor for development of anxiety. However, few studies have examined the unique relationship between behavioral inhibition and obsessive-compulsive disorder (OCD). Therefore, the current study addressed the relationship between behavioral inhibition and OCD in a number of ways. In a large unselected student sample, frequency of current OC symptoms was significantly correlated with retrospective self-reports of total levels of childhood behavioral inhibition. In addition, frequency of current OC symptoms was also significantly correlated with both social and nonsocial components of behavioral inhibition. Further, there was evidence for a unique relationship between behavioral inhibition and OC symptoms beyond the relationship of behavioral inhibition and social anxiety. In addition, results showed that reports of childhood levels of behavioral inhibition significantly predicted levels of OCD symptoms in adulthood. Finally, preliminary evidence suggested that behavioral inhibition may be more strongly associated with some types of OC symptoms than others, and that overprotective parenting may moderate the impact of behavioral inhibition on OC symptoms. The current findings suggest the utility of additional research examining the role of behavioral inhibition in the etiology of OCD.

    Obsessive-compulsive disorder (OCD) and symptoms (OC symptoms) are associated with tic disorders and share an aetiological relationship. The extent to which OCD/OC symptoms are correlated with other hyperkinetic movement disorders is unclear. The aim of this review was to investigate this co-occurrence and the extent to which OCD/OC symptoms and hyperkinetic movement disorders share a neurobiological basis. A systematic review was performed, specifically searching for OCD/OC symptom comorbidity in hyperkinetic movement disorders using case control studies, longitudinal studies and family based studies. The literature search was conducted using PubMed and PsycINFO databases. Heterogeneity of measurement instruments to detect OCD diagnosis and OC symptoms decreased comparability between studies. The most convincing evidence for a relationship was found between the choreas (Huntington's disease and Sydenham's chorea) and OCD/OC symptoms. Furthermore, elevated frequencies of OC symptoms were found in small case control series of dystonias. Small family based studies in dystonia subtypes modestly suggest shared familial/genetic relationships between OC symptoms and dystonia. Current data indicate a relationship between OCD/OC symptoms and the choreas. As OCD and the choreas have been associated with dysfunctional frontal-striatal circuits, the observed relationships might converge at the level of dysfunctions of these circuits. However, paucity of longitudinal and family studies hampers strong conclusions on the nature of the relationship. The relationship between OCD and movement disorders needs further elaboration using larger family based longitudinal studies and sound instruments to characterise OC symptomatology. This could lead to better understanding of the shared pathology between OCD and hyperkinetic movement disorders.

    Body dysmorphic disorder (BDD) and obsessive compulsive disorder (OCD) are associated with elevated depression, suicidality, functional impairment, and days housebound, yet little research has identified risk factors for these outcomes. Using path analysis, the present study examined anxiety and shame as risk factors for these outcomes across Internet-recruited self-report groups (BDD [n = 114], OCD [n = 114], and healthy control [HC; n = 133]). Paths from anxiety and shame to outcomes were similar and mostly significant across BDD and OCD, compared to non-significant paths for HCs, with one exception: the path from shame to depression was significant in the BDD group (b = 0.32) but non-significant in the OCD group (b = 0.07). Findings underscore similarities in BDD and OCD, supporting their reclassification into the same Obsessive Compulsive Related Disorders category. Results emphasize the importance of targeting shame, in addition to anxiety, in treatments for BDD and OCD.

    Patients with obsessive compulsive disorder (OCD) frequently show traits of autism spectrum disorders (ASD). This is one of the first studies to explore the clinical impact of the overlap between OCD and ASD as a categorical diagnosis. A cross-sectional survey in 73 adult outpatients with DSM-IV OCD. Autistic traits were measured using the Autism-Spectrum Quotient (AQ). A clinical estimate ASD diagnosis was made by interview using DSM-IV-TR criteria. OCD patients with and without autistic traits or ASD were compared on demographic and clinical parameters and level of OCD treatment-resistance based on treatment history. Thirty-four (47%) patients scored above the clinical threshold on the AQ (≥26) and 21 (27.8%) met diagnostic criteria for ASD. These diagnoses had not been made before. Patients with autistic traits showed a borderline significant increase in OCD symptom-severity (Yale-Brown Obsessive Compulsive Scale (Y-BOCS); p = .054) and significantly increased impairment of insight (Brown Assessment of Beliefs Scale; p = .01). There was a positive correlation between AQ and Y-BOCS scores (p = .04), but not with OCD treatment resistance. There is a high prevalence of previously undiagnosed ASD in patients with OCD. ASD traits are associated with greater OCD symptom-severity and poor insight.

    Full Text Available Background: Obsessive-compulsive disorder (OCD is a clinically heterogeneous disorder. The previous studies have been conducted to elucidate visuospatial and nonverbal memory deficits in OCD patients. However, they did not reach equivocal results which need to be replicated. Objectives: The current study examines the visuospatial memory in male patients with OCD as compared to normal healthy controls. Materials and Methods: It is a cross-sectional hospital-based study, in which 15 OCD patients and 15 age-, sex-, and education-matched normal healthy controls were chosen by purposive sampling technique. All the participants underwent the Extended Complex Figure Test (ECFT for the assessment of visuospatial memory. Results: Significant difference was found between OCD patients and normal healthy controls on various domains of ECFT. OCD patients performed poorly on copy condition (t = −4.46; P< 0.001, immediate recall (t = −5.20; P< 0.001, delayed recall (t = −5.18; P< 0.001, recognition task (P < 0.001, and matching task (P < 0.001 than the controls. Conclusion: Visuospatial memory was significantly impaired in OCD that included disturbed encoding and impaired visuospatial functioning. Hence, it is important to understand the significance of visuospatial memory in the pathophysiology for OCD diagnosis and therapeutic decision.

    2011-08-01

    Despite elevated rates of obsessive compulsive personality disorder (OCPD) in patients with obsessive compulsive disorder (OCD), no study has specifically examined comorbid OCPD as a predictor of exposure and ritual prevention (EX/RP) outcome. Participants were adult outpatients (n = 49) with primary OCD and a Yale-Brown Obsessive Compulsive Scale (YBOCS) total score ≥ 16 despite a therapeutic serotonin reuptake inhibitor dose for at least 12 weeks prior to entry. Participants received 17 sessions of EX/RP over 8 weeks. OCD severity was assessed with the YBOCS pre- and post-treatment by independent evaluators. At baseline, 34.7% of the OCD sample met criteria for comorbid DSM-IV OCPD, assessed by structured interview. OCPD was tested as a predictor of outcome both as a diagnostic category and as a dimensional score (severity) based on the total number of OCPD symptoms coded as present and clinically significant at baseline. Both OCPD diagnosis and greater OCPD severity predicted worse EX/RP outcome, controlling for baseline OCD severity, Axis I and II comorbidity, prior treatment, quality of life, and gender. When the individual OCPD criteria were tested separately, only perfectionism predicted worse treatment outcome, over and above the previously mentioned covariates. These findings highlight the importance of assessing OCPD and suggest a need to directly address OCPD-related traits, especially perfectionism, in the context of EX/RP to minimize their interference in outcome.

Objective: We aimed to determine the empirical evidence regarding the potential relationship between BDD and obsessive-compulsive disorder (OCD based on the prevalence data, etiopathogenic pathways, and clinical characterization of patients with both disorders. Method: A comprehensive search of databases (PubMed and PsycINFO was performed. Published manuscripts between 1985 and May 2015 were identified. Overall, 53 studies fulfilled inclusion criteria. Results: Lifetime comorbidity rates of BDD–OCD are almost three times higher in samples with a primary diagnosis of BDD than those with primary OCD (27.5% vs 10.4%. However, other mental disorders, such as social phobia or major mood depression, are more likely among both types of psychiatric samples. Empirical evidence regarding the etiopathogenic pathways for BDD–OCD comorbidity is still inconclusive, whether concerning common shared features or one disorder as a risk factor for the other. Specifically, current findings concerning third variables show more divergences than similarities when comparing both disorders. Preliminary data on the clinical characterization of the patients with BDD and OCD indicate that the deleterious clinical impact of BDD in OCD patients is greater than vice versa. Conclusion: Despite the recent inclusion of BDD within the OCDRD, data from comparative studies between BDD and OCD need further evidence for supporting this nosological approach. To better define this issue, comparative studies between BDD, OCD, and social phobia

    Full Text Available Background: Psychological disorders can have a direct impact on family functioning. Family dysfunction is an indirect factor leading to the relapse of psychological disorders. Literature on family dysfunction in anxiety disorder is limited. Role of family and its functioning in obsessive-compulsive disorder (OCD may help in better understanding of the role of social factors in OCD. Aim: The aim was to compare family functions in patients with OCD and compare with controls. Materials and Methods: The sample included 30 cases and 30 age and sex-matched controls. The patients were diagnosed as having OCD using ICD-10 DCR criteria. Yale-Brown Obsessive Compulsive Scale was used to assess the severity of OCD among patients. General Health Questionnaire was used as screening instruments for psychiatric disorder among the control population. Family function was assessed in cases and control using the Family Interaction Patterns Schedule (FIPS. Statistical analysis was performed using SPSS software. Results: Obsessive compulsive disorder patients in comparison controls had significantly increased total FIPS score (P = 0.001. Conclusion: Families with OCD are more significantly impaired in multiple domains of family dynamics than families without member suffering from OCD. It is, therefore, essential that family-based structure effective assessment be sought in the psychosocial management of OCD.

    Background Hoarding behavior may indicate a clinically and possibly etiologically distinct subtype of obsessive compulsive disorder (OCD). Empirical evidence supports a relationship between hoarding and emotional over-attachment to objects. However, little is known about the relationship between hoarding and parental attachment in OCD. Method The study sample included 894 adults diagnosed with DSM-IV OCD who had participated in family and genetic studies of OCD. Participants were assessed for Axis I disorders, personality disorders, and general personality dimensions. The Parental Bonding Instrument (PBI) was used to assess dimensions of perceived parental rearing (care, overprotection, and control). We compared parental PBI scores in the 334 hoarding and 560 non-hoarding participants, separately in men and women. We used logistic regression to evaluate the relationship between parenting scores and hoarding in women, adjusting for other clinical features associated with hoarding. Results In men, there were no significant differences between hoarding and non-hoarding groups in maternal or paternal parenting scores. In women, the hoarding group had a lower mean score on maternal care (23.4 vs. 25.7, poverprotection, and maternal overcontrol are associated with hoarding in women with OCD. Parenting dimensions are not related to hoarding in men. These findings provide further support for a hoarding subtype of OCD and for sex-specific differences in etiologic pathways for hoarding in OCD. PMID:27915218

  19. Inverse reasoning processes in obsessive-compulsive disorder.

    Science.gov (United States)

    Wong, Shiu F; Grisham, Jessica R

    2017-04-01

    The inference-based approach (IBA) is one cognitive model that aims to explain the aetiology and maintenance of obsessive-compulsive disorder (OCD). The model proposes that certain reasoning processes lead an individual with OCD to confuse an imagined possibility with an actual probability, a state termed inferential confusion. One such reasoning process is inverse reasoning, in which hypothetical causes form the basis of conclusions about reality. Although previous research has found associations between a self-report measure of inferential confusion and OCD symptoms, evidence of a specific association between inverse reasoning and OCD symptoms is lacking. In the present study, we developed a task-based measure of inverse reasoning in order to investigate whether performance on this task is associated with OCD symptoms in an online sample. The results provide some evidence for the IBA assertion: greater endorsement of inverse reasoning was significantly associated with OCD symptoms, even when controlling for general distress and OCD-related beliefs. Future research is needed to replicate this result in a clinical sample and to investigate a potential causal role for inverse reasoning in OCD. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The purpose of this study was to determine the neural correlates of excessive habit formation in obsessive-compulsive disorder (OCD). The authors aimed to test for neurobiological convergence with the known pathophysiology of OCD and to infer, based on abnormalities in brain activation, whether these habits arise from dysfunction in the goal-directed or habit system. Thirty-seven OCD patients and 33 healthy comparison subjects learned to avoid shocks while undergoing a functional MRI scan. Following four blocks of training, the authors tested whether the avoidance response had become a habit by removing the threat of shock and measuring continued avoidance. Task-related differences in brain activity in three regions of interest (the caudate, the putamen, and the medial orbitofrontal cortex) were tested at a statistical threshold set at habit formation in OCD patients, which was associated with hyperactivation in the caudate, was observed. Activation in this region was also associated with subjective ratings of increased urge to perform habits. The OCD group, as a whole, showed hyperactivation in the medial orbitofrontal cortex during the acquisition of avoidance; however, this did not relate directly to habit formation. OCD patients exhibited excessive habits that were associated with hyperactivation in a key region implicated in the pathophysiology of OCD, the caudate nucleus. Previous studies indicate that this region is important for goal-directed behavior, suggesting that habit-forming biases in OCD may be a result of impairments in this system, rather than differences in the buildup of stimulus-response habits themselves.

    Previous research has suggested that a deficit in working memory might underlie the difficulty of obsessive-compulsive disorder (OCD) patients to control their thoughts and actions. However, a recent meta-analyses found only small effect sizes for working memory deficits in OCD. Recently, a distinction has been made between declarative and procedural working memory. Working memory in OCD was tested mostly using declarative measurements. However, OCD symptoms typically concerns actions, making procedural working-memory more relevant. Here, we tested the operation of procedural working memory in OCD. Participants with OCD and healthy controls performed a battery of choice reaction tasks under high and low procedural working memory demands. Reaction-times (RT) were estimated using ex-Gaussian distribution fitting, revealing no group differences in the size of the RT distribution tail (i.e., τ parameter), known to be sensitive to procedural working memory manipulations. Group differences, unrelated to working memory manipulations, were found in the leading-edge of the RT distribution and analyzed using a two-stage evidence accumulation model. Modeling results suggested that perceptual difficulties might underlie the current group differences. In conclusion, our results suggest that procedural working-memory processing is most likely intact in OCD, and raise a novel, yet untested assumption regarding perceptual deficits in OCD.

    Research suggests that obsessive-compulsive disorder (OCD) is not a unitary entity, but rather a highly heterogeneous condition, with complex and variable clinical manifestations. The aims of this study were to compare clinical and demographic characteristics of OCD patients with early and late age of onset of obsessive-compulsive symptoms (OCS); and to compare the same features in early onset OCD with and without tics. The independent impact of age at onset and presence of tics on comorbidity patterns was investigated. Three hundred and thirty consecutive outpatients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for OCD were evaluated: 160 patients belonged to the "early onset" group (EOG): before 11 years of age, 75 patients had an "intermediate onset" (IOG), and 95 patients were from the "late onset" group (LOG): after 18 years of age. From the 160 EOG, 60 had comorbidity with tic disorders. The diagnostic instruments used were: the Yale-Brown Obsessive Compulsive Scale and the Dimensional Yale-Brown Obsessive Compulsive Scale (DY-BOCS), Yale Global Tics Severity Scale, and Structured Clinical Interview for DSM-IV Axis I Disorders-patient edition. Statistical tests used were: Mann-Whitney, full Bayesian significance test, and logistic regression. The EOG had a predominance of males, higher frequency of family history of OCS, higher mean scores on the "aggression/violence" and "miscellaneous" dimensions, and higher mean global DY-BOCS scores. Patients with EOG without tic disorders presented higher mean global DY-BOCS scores and higher mean scores in the "contamination/cleaning" dimension. The current results disentangle some of the clinical overlap between early onset OCD with and without tics.

    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.

    Cognitive functioning in individuals with Obsessive Compulsive Disorder (OCD) and with Obsessive Compulsive Personality Disorder (OCPD) has not been adequately studied. Examine the cognitive flexibility and planning ability of individuals with OCD and OCPD. Twenty patients with OCD and 25 patients with OCPD who had not taken medication in the previous two weeks were identified in an outpatient psychology clinic in Tehran, and 25 healthy control subjects were identified from the university staff and local community residents. All participants were administered the 28-item version of the General Health Questionnaire (GHQ-28), the Wisconsin Card Sorting Test (WCST), and the Tower of London (TOL) test. Two measures of the WCTS (number of perseverative errors and number of categories completed) were used to assess cognitive flexibility and three measures of the TOL (total number of moves in 12 trials, total response time, and planning time) were used to assess planning ability. The level of current psychological distress in the two patient groups was significantly greater than that in the control group. After adjusting for demographic variables and the level of psychological distress, both OCD patients and OCPD patients made more perseverative errors on the WCST than control subjects, and the OCD patients (but not the OCPD patients) completed significantly fewer categories than the control subjects. Both the OCD patients and OCPD patients required significantly more moves than control subjects to complete the 12 TOL tasks and OCD patients took significantly longer than both OCPD patients and control subjects to complete the tasks. Individuals with OCD and OCPD have impaired cognitive flexibility and planning ability compared to healthy controls, and there are some differences in these measures of cognitive functioning between OCD and OCPD.

    Hypochondriasis is a heterogeneous disorder. This was well demonstrated in the study by Kellner et al, which showed that patients with high levels of disease fear tended to be more anxious or phobic, whereas patients with high levels of disease conviction tended to have more and more severe somatic symptoms. Little comorbidity exists to support the statement that hypochondriasis is an obsessive-compulsive spectrum disorder. Although patients exist whose hypochondriac concerns are identical in quality to the intrusive thoughts of patients with OCD, as a group, patients with hypochondriasis do not share a comorbidity profile comparable with that of patients with OCD. The data support a closer relationship between hypochondriasis and somatization disorder than between hypochondriasis and OCD. The family history data is limited by the lack of adequate studies. Using comparable methods of the family history approach, Black's study reported a higher frequency of GAD but not OCD among the relatives of OCD patients--a finding similar to what Noyes found among the relatives of hypochondriac patients; however, using the direct interview method, somatization disorder was the only statistically more common disorder, among relatives of female hypochondriac patients. Therefore, although the parallel in overlap with GAD is suggestive of a commonality between OCD, GAD, and hypochondriasis, the finding of a greater frequency of somatization disorder leans against the hypothesis that hypochondriasis is best considered an OCD spectrum disorder. The pharmacologic treatment data are the one type of biologic evidence that supports a bridge to OCD. The pharmacologic studies suggest that for patients with general hypochondriasis, TCAs are not effective and that higher dosages and longer trials of the SRIs are needed. These pharmacologic observations are comparable with the ones made for patients with OCD but dissimilar to the observations made for depression. The benefit of imipramine

    The emotion of guilt plays a pivotal role in the genesis and maintenance of Obsessive-Compulsive Disorder (OCD). But what kind of guilt do OC patients want to prevent? Several studies suggest the existence of two different types of guilt emotions, namely deontological and altruistic guilt. This research suggests that the former, more than the latter, is involved in OCD. Studies in which people must hypothetically choose between killing one person to save a few (consequentialist choice) or take no action and allow things to take their course (omission choice), have found that the latter is consistent with the "Do not play God" moral principle whereas the former is consistent with altruistic motivations. This paper is aimed at verifying whether both OC patients, with no induction, and nonclinical participants, after the induction of deontological guilt prefer omission more often than a consequentialist option. It is hypothesized that people with OCD will be motivated to avoid feeling deontological guilt and thus will be more likely to opt for omission. Similarly, nonclinical participants who receive a deontological guilt induction will also be more likely to choose omission. In two studies participants were given seven scenarios (four moral dilemmas, three control scenarios). Twenty patients with OCD, 20 anxious controls, and 20 healthy participants took part in study 1. In study 2, we recruited 70 healthy participants who were randomly assigned to receive a deontological guilt or a control induction. Consistent with hypotheses, in Study 1 OC patients preferred omission, instead of the consequentialist option, moreso than did the clinical and nonclinical controls. In Study 2, the group receiving the deontological guilt induction preferred omission to a greater extent than did the altruistic group. The present study cannot establish that the goal of preventing or neutralizing deontological guilt actually drives obsessions and compulsions. These results provide further

    Full Text Available Obsessive–compulsive disorder (OCD is a neuropsychiatric illness that often develops in childhood, affects 1%–2% of the population, and causes significant impairment across the lifespan. The first step in identifying and treating OCD is a thorough evidence-based assessment. This paper reviews the administration pragmatics, psychometric properties, and limitations of commonly used assessment measures for adults and youths with OCD. This includes diagnostic interviews, clinician-administered symptom severity scales, self-report measures, and parent/child measures. Additionally, adjunctive measures that assess important related factors (ie, impairment, family accommodation, and insight are also discussed. This paper concludes with recommendations for an evidence-based assessment based on individualized assessment goals that include generating an OCD diagnosis, determining symptom severity, and monitoring treatment progress.

    Obsessive compulsive disorder (OCD) and attention deficit hyperactivity disorder (ADHD) are two of the most common neuropsychiatric diseases in paediatric populations. The high comorbidity of ADHD and OCD with each other, especially of ADHD in paediatric OCD, is well described. OCD and ADHD often follow a chronic course with persistent rates of at least 40-50 %. Family studies showed high heritability in ADHD and OCD, and some genetic findings showed similar variants for both disorders of the same pathogenetic mechanisms, whereas other genetic findings may differentiate between ADHD and OCD. Neuropsychological and neuroimaging studies suggest that partly similar executive functions are affected in both disorders. The deficits in the corresponding brain networks may be responsible for the perseverative, compulsive symptoms in OCD but also for the disinhibited and impulsive symptoms characterizing ADHD. This article reviews the current literature of neuroimaging, neurochemical circuitry, neuropsychological and genetic findings considering similarities as well as differences between OCD and ADHD.

It has been suggested that the reduced cognitive inhibition observed in both schizotypy and OCD may result in the frequent entry into awareness of unacceptable urges and intrusive thoughts. The aim of this study was to investigate the relationship between the severity of obsession or compulsion and schizotypy in OCD.Patients and methods: Sixty subjects (25 males and 35 females who were OCD outpatients in the University Hospital at the Kyoto Prefectural University of Medicine during the period 2008–2010 were enrolled in the study. Assessments of these patients were made using the Yale–Brown Obsessive Compulsive Scale (Y-BOCS, the Schizotypal Personality Questionnaire (SPQ, the Hamilton Depression Rating Scale (HAM-D, and the Hamilton Anxiety Rating Scale (HAM-A. The Pearson correlation coefficients between Y-BOCS and SPQ scores were calculated. Furthermore, hierarchical multiple linear regression analyses were conducted to assess whether schizotypy predicted the severity of obsession and compulsion.Results: By calculating the Pearson correlation coefficient, it was found that the Y-BOCS obsession score, not the Y-BOCS compulsion score, was correlated with the SPQ total score. Results of the hierarchical multiple linear regression analysis showed that SPQ total score was a significant predictor of the Y-BOCS obsession score, after accounting for control

    Full Text Available Abstract Objective The study aimed to investigate phenomenology, psychiatric comorbidity, and family history of obsessive-compulsive disorder (OCD in a clinical sample of normally developing preschool children with OCD. Method Subjects in this study were recruited from a clinical sample of preschool children (under 72 months of age who were referred to a university clinic. Subjects with a normal developmental history and significant impairment related to OCD symptoms were included in the study. Children’s Yale-Brown Obsessive-Compulsive Scale was used to assess OCD symptoms. Each subject was assessed for comorbid DSM-IV psychiatric disorders using a semi-structured interview. Parents were evaluated for lifetime history of OCD in individual sessions. Results Fifteen boys and ten girls (age range: 28 to 69 months; 54.12±9.08 months were included. Mean age of onset of OCD was 35.64±13.42 months. All subjects received at least one comorbid diagnosis. The most frequent comorbid disorders were non-OCD anxiety disorders (n=17; 68.0%, attention-deficit hyperactivity disorder (ADHD (n=15; 60.0%, oppositional defiant disorder (ODD (n=12; 48.0%, and tic disorders (n=6; 24.0%. Mean number of comorbid disorders was 3.65 and 2.35 for boys and girls, respectively. At least one parent received lifetime OCD diagnosis in 68 percent of the subjects. Conclusions The results indicated that OCD in referred preschool children is more common in males, highly comorbid with other psychiatric disorders, and associated with high rates of family history of OCD. Given the high rates of comorbidity and family history, OCD should be considered in referred preschool children with disruptive behavior disorders and/or with family history of OCD.

    Full Text Available Kelda H Walsh, Christopher J McDougleDepartment of Psychiatry, Indiana University School of Medicine, Indianapolis, IN, USAAbstract: Obsessive-compulsive disorder (OCD is a chronic anxiety disorder. While medication and psychotherapy advances have been very helpful to patients, many patients do not respond adequately to initial trials of serotonergic medication or cognitive-behavioral therapy (CBT and require multiple treatment trials or combination therapies. Comorbidity may also influence treatment response. The role of streptococcal infections in pediatric OCD has become an area of intense scrutiny and controversy. In this article, current treatment methods for OCD will be reviewed, with special attention to strategies for treating OCD in children and in patients with comorbid tic disorders. Alternative psychotherapy strategies for patients who are highly anxious about starting CBT, such as cognitive therapy or augmentation with D-cycloserine, will be reviewed. Newer issues regarding use of antibiotics, neuroleptics, and glutamate modulators in OCD treatment will also be explored.Keywords: OCD, exposure/response prevention therapy, PANDAS, tic disorder

    Full Text Available The comorbidity of bipolar disorder and anxiety disorders is a well known concept. Obsessive-compulsive disorder is the most commonly seen comorbid anxiety disorder in bipolar patients. Some genetic variants, neurotransmitters especially serotonergic systems and second-messenger systems are thought to be responsible for its etiology. Bipolar disorder alters the clinical aspects of obsessive compulsive disorder and is associated with poorer outcome. The determination of comorbidity between bipolar disorder and obsessive compulsive disorder is quite important for appropriate clinical management and treatment.

    To evaluate the clinical features of obsessive-compulsive disorder (OCD) patients with comorbid tic disorders (TD) in a large, multicenter, clinical sample. A cross-sectional study was conducted that included 813 consecutive OCD outpatients from the Brazilian OCD Research Consortium and used several instruments of assessment, including the Yale-Brown Obsessive-Compulsive Scale, the Dimensional Yale-Brown Obsessive-Compulsive Scale, the Yale Global Tic Severity Scale (YGTSS), the USP Sensory Phenomena Scale, and the Structured Clinical Interview for DSM-IV Axis I Disorders. The sample mean current age was 34.9 years old (SE 0.54), and the mean age at obsessive-compulsive symptoms (OCS) onset was 12.8 years old (SE 0.27). Sensory phenomena were reported by 585 individuals (72% of the sample). The general lifetime prevalence of TD was 29.0% (n = 236), with 8.9% (n = 72) presenting Tourette syndrome, 17.3% (n = 141) chronic motor tic disorder, and 2.8% (n = 23) chronic vocal tic disorder. The mean tic severity score, according to the YGTSS, was 27.2 (SE 1.4) in the OCD + TD group. Compared to OCD patients without comorbid TD, those with TD (OCD + TD group, n = 236) were more likely to be males (49.2% vs. 38.5%, p disorders in general: separation anxiety disorder, social phobia, specific phobia, generalized anxiety disorder, post-traumatic stress disorder, attention-deficit hyperactivity disorder, impulse control disorders in general, and skin picking. Also, the "aggressive," "sexual/religious," and "hoarding" symptom dimensions were more severe in the OCD + TD group. Tic-related OCD may constitute a particular subgroup of the disorder with specific phenotypical characteristics, but its neurobiological underpinnings remain to be fully disentangled.

    The Internet is increasingly used as a source of information for mental health issues. The burden of obsessive compulsive disorder (OCD) may lead persons with diagnosed or undiagnosed OCD, and their relatives, to search for good quality information on the Web. This study aimed to evaluate the quality of Web-based information on English-language sites dealing with OCD and to compare the quality of websites found through a general and a medically specialized search engine. Keywords related to OCD were entered into Google and OmniMedicalSearch. Websites were assessed on the basis of accountability, interactivity, readability, and content quality. The "Health on the Net" (HON) quality label and the Brief DISCERN scale score were used as possible content quality indicators. Of the 235 links identified, 53 websites were analyzed. The content quality of the OCD websites examined was relatively good. The use of a specialized search engine did not offer an advantage in finding websites with better content quality. A score ≥16 on the Brief DISCERN scale is associated with better content quality. This study shows the acceptability of the content quality of OCD websites. There is no advantage in searching for information with a specialized search engine rather than a general one. The Internet offers a number of high quality OCD websites. It remains critical, however, to have a provider-patient talk about the information found on the Web.

    Previous studies show that individuals with obsessive compulsive disorder (OCD) accord more importance than healthy controls (HC) to alternative conclusions, resulting in increased doubt regarding an initial conclusion. The goal of the present study was to replicate and extend this finding. Eighteen participants diagnosed with OCD and 16 HC completed the Reasoning with Inductive Arguments Task (RIAT), which operationalizes doubt as change in confidence towards a conclusion after alternative conclusions are presented. To examine conditions that facilitate doubt, the impact of alternative conclusions that both supported and contradicted the initial conclusion was compared, as well as the effect of neutral and OCD-relevant item content. Both the OCD and HC groups decreased confidence after contradicting conclusions, but only the HC group increased confidence when presented with supporting conclusions. Furthermore, decrease in confidence in the OCD group correlated with OCD symptom severity. The RIAT could be adapted to better take into account of OCD subtypes.

    Obsessive-compulsive disorder (OCD) is a severe psychiatric condition that is, among other features, characterized by marked impairment in social functioning. Although theoretically plausible with regard to neurobiological underpinnings of OCD, there is little research about possible impairments in social cognitive and meta-cognitive abilities and their connections with social functioning in patients with OCD. Accordingly, we sought to examine social cognitive skills and metacognition in OCD. Twenty OCD patients and age-, sex-, and education-matched 20 healthy controls were assessed using neurocognitive and diverse social cognitive skills including the Ekman 60 Faces test, the Hinting Task, the faux pas test, and a proverb test. In addition, the Metacognition Questionnaire-30 was administered to both the OCD and the control groups. Social functioning was measured using the Personal and Social Performance Scale. Symptom severity in patients was determined by the Yale-Brown Obsessive-Compulsive Scale and the Maudsley Obsessive-Compulsive Inventory. No group differences emerged in basic social cognitive abilities. In contrast, compared to controls, OCD patients scored higher on all MCQ dimensions, particularly negative beliefs about worry, uncontrollability, and danger; beliefs about need to control thoughts; and cognitive self-consciousness. There were no significant correlations between social or metacognitive parameters and OCD symptom severity. However, in the patient group, depression and metacognition predicted social functioning. OCD patients show normal basal social cognitive abilities, but dysfunctional metacognitive profiles, which may contribute to their psychosocial impairment.

    The error-related negativity (ERN) is a negative deflection in the event-related potential after an incorrect response, which is often increased in patients with obsessive-compulsive disorder (OCD). However, the relation of the ERN to comorbid tic disorders has not been examined in patients with OCD. This study compared ERN amplitudes in patients with tic-related OCD, patients with non-tic-related OCD, and healthy controls. The ERN, correct response negativity, and error number were measured during an Eriksen flanker task to assess performance monitoring in 44 youth with a lifetime diagnosis of OCD and 44 matched healthy controls ranging in age from 10 to 19 years. Nine youth with OCD had a lifetime history of tics. ERN amplitude was significantly increased in patients with OCD compared with healthy controls. ERN amplitude was significantly larger in patients with non-tic-related OCD than in patients with tic-related OCD or controls. ERN amplitude had a significant negative correlation with age in healthy controls but not in patients with OCD. Instead, in patients with non-tic-related OCD, ERN amplitude had a significant positive correlation with age at onset of OCD symptoms. ERN amplitude in patients was unrelated to OCD symptom severity, current diagnostic status, or treatment effects. The results provide further evidence of increased error-related brain activity in pediatric OCD. The difference in the ERN between patients with tic-related and those with non-tic-related OCD provides preliminary evidence of a neurobiological difference between these two OCD subtypes. The results indicate the ERN is a trait-like measurement that may serve as a biomarker for non-tic-related OCD. Copyright © 2012 American Academy of Child and Adolescent Psychiatry.

    Although an inflated sense of responsibility, thought-action fusion, and thought suppression are influential factors in cognitive models of obsessive-compulsive disorder (OCD), their impact on OCD has generally been demonstrated in samples from Western countries. The aim of the present study is to evaluate these cognitive factors in Turkish patients with OCD, other anxiety disorders, and community controls. Group comparisons showed that responsibility based on self-dangerousness and thought suppression significantly distinguished OCD patients from patients with other anxiety disorders and controls. Moreover, correlation and discriminant function analyses indicated that thought-action fusion in morality and likelihood was also associated with OCD symptoms. The present findings provide support for the international validity and specificity of cognitive factors and model for OCD.

    The present study aims to compare the unwanted intrusions experienced by obsessive-compulsive (OCD) and eating disorder (ED) patients, their appraisals, and their control strategies and analyse which variables predict the intrusions' disruption and emotional disturbance in each group. Seventy-nine OCD and 177 ED patients completed two equivalent self-reports designed to assess OCD-related and ED-related intrusions, their dysfunctional appraisals, and associated control strategies. OCD and ED patients experienced intrusions with comparable frequency and emotional disturbance, but OCD patients experienced greater disruption. Differences appeared between groups on some appraisals and control strategies. Intolerance to uncertainty (OCD group) and thought importance (ED group) predicted their respective emotional disturbance and disruption. Additionally, control importance (OCD group) and thought-action fusion moral (OCD and ED groups) predicted their emotional disturbance. OCD and ED share the presence of intrusions; however, different variables explain why they are disruptive and emotionally disturbing. Cognitive intrusions require further investigation as a transdiagnostic variable. Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.

    Although central to any exhaustive theory of human subjectivity, the relationship between dream and waking consciousness remains uncertain. Some findings suggest that dream consciousness can be influenced by severe disorders of thought content. The suppression of unwanted thoughts has been shown to influence dream content in healthy individuals. In order to better define this phenomenon, we evaluated the persistence of obsessive/compulsive themes across the dream and waking cognition of OCD patients and in a control group of healthy subjects. Participants were administered a shortened version of the Thematic Apperception Test to produce a waking fantasy narration, and were trained to keep a dream diary. Dream and waking narrative contents were analyzed in order to recognize obsessive/compulsive themes, and to calculate Mean Dream Obsession/Compulsion (MDO, MDC) and Mean TAT Obsession/Compulsion (MTO, MTC) parameters. No differences were found between the two populations in terms of MDO, MDC, MTO, nor MTC. Density of obsessive and compulsive themes were significantly higher in dream reports than in waking narratives for both groups. No correlation was observed between MDO/MDC scores and Y-BOCS obsession/compulsion scores in the OCD group. These findings strengthen the discontinuity hypothesis, suggesting that ruminative aspects of cognition are somehow interrupted during dream activity. Copyright © 2016 Elsevier Ireland Ltd.

  4. Early childhood experiences shaping vulnerability to Obsessive-Compulsive Disorder

    Full Text Available According to the literature, inflated responsibility/sensitivity to guilt play a pivotal role in both the genesis and maintenance of Obsessive-Compulsive Disorder (OCD. They may be learned in childhood and adolescence, through particular experiences and parental rearing styles, involving criticism, excessively high standards, and social moralization. Preliminary data on the role of dysfunctional beliefs in the development/maintenance of OCD also show that non-affected family members of OC individuals score higher than controls in domains concerning responsibility, suggesting it might represent a candidate endophenotype for the disorder. Compulsive conducts, that far from being mechanical reactions are instead clearly goal-oriented, may be triggered by the need of preventing responsibility/guilt. Therefore, useful psychological interventions aimed at not only reappraising meanings associated with the specific early experiences connected to hyper-sensitivity to guilt, but also at developing a more general compassionate and forgiving stance towards oneself, may prove particularly effective.

    Background With the advent of the fifth edition of Diagnostic and Statistical Manual of Mental Disorders, body dysmorphic disorder (BDD) has been subsumed into the obsessive-compulsive disorders and related disorders (OCDRD) category. Objective We aimed to determine the empirical evidence regarding the potential relationship between BDD and obsessive-compulsive disorder (OCD) based on the prevalence data, etiopathogenic pathways, and clinical characterization of patients with both disorders. Method A comprehensive search of databases (PubMed and PsycINFO) was performed. Published manuscripts between 1985 and May 2015 were identified. Overall, 53 studies fulfilled inclusion criteria. Results Lifetime comorbidity rates of BDD–OCD are almost three times higher in samples with a primary diagnosis of BDD than those with primary OCD (27.5% vs 10.4%). However, other mental disorders, such as social phobia or major mood depression, are more likely among both types of psychiatric samples. Empirical evidence regarding the etiopathogenic pathways for BDD–OCD comorbidity is still inconclusive, whether concerning common shared features or one disorder as a risk factor for the other. Specifically, current findings concerning third variables show more divergences than similarities when comparing both disorders. Preliminary data on the clinical characterization of the patients with BDD and OCD indicate that the deleterious clinical impact of BDD in OCD patients is greater than vice versa. Conclusion Despite the recent inclusion of BDD within the OCDRD, data from comparative studies between BDD and OCD need further evidence for supporting this nosological approach. To better define this issue, comparative studies between BDD, OCD, and social phobia should be carried out. PMID:26345330

    Various studies have shown that obsessive-compulsive symptoms exist as part of not only obsessive-compulsive disorder (OCD) but also obsessive-compulsive personality disorder (OCPD). Despite these shared characteristics, there is an ongoing debate on the inclusion of OCPD into the recently developed DSM-5 obsessive-compulsive and related disorders (OCRDs) category. The current study aims to clarify whether this inclusion can be justified from an item response theory approach. The validity of the continuity model for understanding the association between OCD and OCPD was explored in 787 Dutch community and referred adolescents (70% female, 12-20 years old, mean = 16.16, SD = 1.40) studied between July 2011 and January 2013, relying on item response theory (IRT) analyses of self-reported OCD symptoms (Youth Obsessive-Compulsive Symptoms Scale [YOCSS]) and OCPD traits (Personality Inventory for DSM-5 [PID-5]). The results support the continuity hypothesis, indicating that both OCD and OCPD can be represented along a single underlying spectrum. OCD, and especially the obsessive symptom domain, can be considered as the extreme end of OCPD traits. The current study empirically supports the classification of OCD and OCPD along a single dimension. This integrative perspective in OC-related pathology addresses the dimensional nature of traits and psychopathology and may improve the transparency and validity of assessment procedures. © Copyright 2014 Physicians Postgraduate Press, Inc.

    This article examines whether self-worth contingencies in the personal domains of cleanliness, morality, hoarding, certainty, accuracy, religion and respect for others have specific associations with obsessive symptoms and cognitions in individuals with obsessive-compulsive disorder (OCD). Fifty-seven patients with a primary diagnosis of OCD completed the Obsessional Concerns and Self Questionnaire (OCSQ), designed to assess the extent to which respondents consider OCD content domains relevant to their self-worth, along with a battery of other instruments. Results indicate that the OCSQ is more associated with OCD than with non-OCD anxiety symptoms, and that it is also associated with comorbid depressive symptoms in OCD patients. Moreover, the OCSQ-Order and Cleanliness and Hoarding dimensions are associated with their symptom counterparts (i.e., contamination, checking, order, hoarding and neutralizing). OCSQ domains were highly associated with dysfunctional beliefs about obsessions. However, only the OCSQ scores, but not the dysfunctional beliefs, predicted OCD symptoms. These results support cognitive conceptualizations implicating self-concept in OCD development, and they suggest the need to further analyze the influence of self-worth in OCD development and maintenance.

    Irritable bowel syndrome (IBS) occurs more frequently in psychiatric patients, especially those with anxiety and mood disorders. We sought to determine the prevalence and phenomenology of IBS in patients diagnosed with obsessive-compulsive disorder (OCD). A semi-structured diagnostic interview was administered to patients seeking treatment for OCD in outpatient settings. Structured questions regarding gastrointestinal functioning and IBS symptoms were administered. IBS was diagnosed by a gastroenterologist using Rome I criteria. Thirty-seven patients (35.1%) with OCD met criteria for IBS. Of these, 53.8% had IBS with both diarrhea and constipation, 30.8% had diarrhea-predominant IBS, and 15.4% had constipation-predominant IBS. The prevalence rate of IBS in an age- and sex-matched control group (n=40) of medical patients in a family practice was 2.5%. IBS prevalence rates were significantly higher for OCD patients than control subjects (P=.0002). IBS and psychiatric illness have high rates of bi-directional comorbidity. This study shows that 35.1% of patients with OCD satisfied criteria for IBS in contrast to 2.5% of the controlled subjects. In most patients the IBS was characterized by both diarrhea and constipation. While taking the initial history clinicians should inquire about bowel symptoms in patients presenting with psychiatric illnesses, including OCD. SSRIs could potentially worsen such symptoms and lead to non-adherence.

    2018-05-01

    Cognitive theorists posit that inflated responsibility beliefs contribute to the development of obsessive compulsive disorder (OCD). Salkovskis et al. (1999) proposed that experiencing heightened responsibility, overprotective parents and rigid rules, and thinking one influenced or caused a negative life event act as 'pathways' to the development of inflated responsibility beliefs, thereby increasing risk for OCD. Studies in adults with OCD and non-clinical adolescents support the link between these experiences and responsibility beliefs (Coles et al., 2015; Halvaiepour and Nosratabadi, 2015), but the theory has never been tested in youth with current OCD. We provided an initial test of the theory by Salkovskis et al. (1999) in youth with OCD. We predicted that childhood experiences proposed by Salkovskis et al. (1999) would correlate positively with responsibility and harm beliefs and OCD symptom severity. Twenty youth with OCD (age 9‒16 years) completed a new child-report measure of the experiences hypothesized by Salkovskis et al. (1999), the Pathways to Inflated Responsibility Beliefs Scale-Child Version (PIRBS-CV). Youth also completed the Obsessive Beliefs Questionnaire-Child Version (Coles et al., 2010) and the Obsessive Compulsive Inventory-Child Version (Foa et al., 2010). Consistent with hypotheses, the PIRBS-CV was significantly related to responsibility and harm beliefs and OCD symptom severity. Results provide initial support for the theory proposed by Salkovskis et al. (1999) as applied to youth with OCD. Future studies are needed to further assess the model in early-onset OCD.

    Conclusion: High prevalence of sexual dysfunction in OCD women and significant correlation between male sexual dysfunction and OCD (r= -481.0 between total score of OCI-R with erectile dysfunction and r= -458.0 between total score of OCI-R and sexual satisfaction could confirm a relation between OCD and sexual disorders. So, evaluation of sexual function in all patients with OCD is recommended.

    The present study attempted to assess the dissociative symptoms and overall dissociative disorder comorbidity in patients with obsessive-compulsive disorder (OCD). In addition, we examined the relationship between the severity of obsessive-compulsive symptoms and dissociative symptoms. All patients admitted for the first time to the psychiatric outpatient unit were included in the study. Seventy-eight patients had been diagnosed as having OCD during the 2-year study period. Patients had to meet the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for OCD. Most (76.9%; n = 60) of the patients were female, and 23.1% (n = 18) of the patients were male. Dissociation Questionnaire was used to measure dissociative symptoms. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Dissociative Disorders interviews and Yale-Brown Obsessive Compulsive Checklist and Severity Scale were used. Eleven (14%) of the patients with OCD had comorbid dissociative disorder. The most prevalent disorder in our study was dissociative depersonalization disorder. Dissociative amnesia and dissociative identity disorder were common as well. The mean Yale-Brown score was 23.37 ± 7.27 points. Dissociation Questionnaire scores were between 0.40 and 3.87 points, and the mean was 2.23 ± 0.76 points. There was a statistically significant positive correlation between Yale-Brown points and Dissociation Questionnaire points. We conclude that dissociative symptoms among patients with OCD should alert clinicians for the presence of a chronic and complex dissociative disorder. Clinicians may overlook an underlying dissociative process in patients who have severe symptoms of OCD. However, a lack of adequate response to cognitive-behavioral and drug therapy may be a consequence of dissociative process. Copyright © 2012 Elsevier Inc. All rights reserved.

    Recent studies have challenged the anxiety-avoidance model of obsessive-compulsive disorder (OCD), linking OCD to impulsivity, risky-decision-making and reward-system dysfunction, which can also be found in addiction and might support the conceptualization of OCD as a behavioral addiction. Here, we conducted an exploratory investigation of the behavioral addiction model of OCD by assessing whether OCD patients are more impulsive, have impaired decision-making, and biased probabilistic reasoning, three core dimensions of addiction, in a sample of OCD patients and healthy controls. We assessed these dimensions on 38 OCD patients and 39 healthy controls with the Barratt Impulsiveness Scale (BIS-11), the Iowa Gambling Task (IGT) and the Beads Task. OCD patients had significantly higher BIS-11 scores than controls, in particular on the cognitive subscales. They performed significantly worse than controls on the IGT preferring immediate reward despite negative future consequences, and did not learn from losses. Finally, OCD patients demonstrated biased probabilistic reasoning as reflected by significantly fewer draws to decision than controls on the Beads Task. OCD patients are more impulsive than controls and demonstrate risky decision-making and biased probabilistic reasoning. These results might suggest that other conceptualizations of OCD, such as the behavioral addiction model, may be more suitable than the anxiety-avoidance one. However, further studies directly comparing OCD and behavioral addiction patients are needed in order to scrutinize this model.

    The use of computers, especially for virtual reality (VR), to understand, assess, and treat various mental health problems has been developed for the last decade, including application for phobia, post-traumatic stress disorder, attention deficits, and schizophrenia. However, the number of VR tools addressing obsessive-compulsive disorder (OCD) is still lacking due to the heterogeneous symptoms of OCD and poor understanding of the relationship between VR and OCD. This article reviews the empirical literatures for VR tools in the future, which involve applications for both clinical work and experimental research in this area, including examining symptoms using VR according to OCD patients' individual symptoms, extending OCD research in the VR setting to also study behavioral and physiological correlations of the symptoms, and expanding the use of VR for OCD to cognitive-behavioral intervention.

  15. Glutamate abnormalities in obsessive compulsive disorder: neurobiology, pathophysiology, and treatment.

    Obsessive compulsive disorder is prevalent, disabling, incompletely understood, and often resistant to current therapies. Established treatments consist of specialized cognitive-behavioral psychotherapy and pharmacotherapy with medications targeting serotonergic and dopaminergic neurotransmission. However, remission is rare, and more than a quarter of OCD sufferers receive little or no benefit from these approaches, even when they are optimally delivered. New insights into the disorder, and new treatment strategies, are urgently needed. Recent evidence suggests that the ubiquitous excitatory neurotransmitter glutamate is dysregulated in OCD, and that this dysregulation may contribute to the pathophysiology of the disorder. Here we review the current state of this evidence, including neuroimaging studies, genetics, neurochemical investigations, and insights from animal models. Finally, we review recent findings from small clinical trials of glutamate-modulating medications in treatment-refractory OCD. The precise role of glutamate dysregulation in OCD remains unclear, and we lack blinded, well-controlled studies demonstrating therapeutic benefit from glutamate-modulating agents. Nevertheless, the evidence supporting some important perturbation of glutamate in the disorder is increasingly strong. This new perspective on the pathophysiology of OCD, which complements the older focus on monoaminergic neurotransmission, constitutes an important focus of current research and a promising area for the ongoing development of new therapeutics.

    It is known that obsessive-compulsive disorder (OCD) patients with poor insight display more severe neuropsychological impairments than other patients with OCD. There are limited studies of OCD and theory of mind (ToM). To investigate ToM skills in patients with OCD and the relationship between insight and ToM skills by comparing OCD patients with good and poor insight. Eighty patients with OCD and 80 healthy controls completed the structured clinical interview for DSM-IV axis I disorders, the Yale Brown Obsessive-Compulsive Scale, the Beck Anxiety and Beck Depression Inventories, and the Brown Assessment of Beliefs Scale. To assess ToM skills, first- and second-order false-belief tests, a hinting test, a faux pas test, a reading the mind in the eyes test, and a double-bluff test were administered. Patients with OCD had poorer ToM abilities than healthy controls. All ToM scores were significantly lower in the poor insight group than in the good insight group (p insight than in OCD with good insight may contribute to the idea of OCD with poor insight being a subtype with different clinical and neuropsychological characteristics.

    This paper examines the contribution of incompleteness/'not just right experiences' (NJREs) to an understanding of the relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality traits (OCPTs). It investigates the association of specific OCD symptom dimensions with OCPTs, conceptualized as continuous phenomena that are also observable below the diagnostic threshold. As empirical findings and clinical observation suggest that incompleteness feelings/NJREs may play a significant affective and motivational role for certain OCD subtypes, but also for patients with accentuated OCPTs, we hypothesized that OCPTs are selectively linked with incompleteness-associated OCD symptom dimensions (ordering, checking, hoarding and counting). Moreover, we assumed that this selective relationship cannot be demonstrated any more after statistical control of incompleteness, whereas it is preserved after statistical control of anxiety, depression, pathological worry and harm avoidance. Results from a study with a large clinical sample (n = 185) partially support these hypotheses and suggest that NJREs may be an important connecting link between specific OCD symptom dimensions, in particular ordering and checking, and accentuated OCPTs. Obsessive-compulsive personality traits (OCPTs) are positively related to obsessive-compulsive disorder symptom dimensions (ordering, checking, hoarding and counting) hypothesized or found to be associated with incompleteness/'not just right experiences' (NJREs), but not to washing and obsessions. This positive relationship, which is strongest for ordering and checking, is eliminated when NJREs are statistically controlled. Ordering, checking and accentuated OCPTs may share NJREs as a common affective-motivational underpinning.Dysfunctional behaviour patterns of people with accentuated OCPTs or obsessive-compulsive personality disorder (OCPD) may be viewed as efforts to avoid or reduce subjectively intolerable NJREs

    2000-01-01

    In this article, which is the first in a three-part series, the authors provide an overview of the current state of our knowledge of the phenomenology, etiology, and diagnosis of OCD. The DSM-IV criteria for OCD are presented and explicated. Disorders that are commonly comorbid with OCD (e.g., major depressive disorder, other anxiety dis-orders, Tourette's disorder) are described. The authors also discuss disorders such as body dysmorphic disorder that may be related to OCD and are often termed OCD spectrum disorders. OCD is likely to have multiple causes and the authors discuss behavioral, neuroanatomical, and neurochemical theories of OCD. Two treatments have demonstrated efficacy in OCD, cognitive-behavioral therapy and pharmacotherapy with serotonergic reuptake inhibitors, and the authors discuss how these treatments may work in light of what is known about the etiology of the disorder. The different subtypes of OCD that have been proposed are described along with their implications for treatment. The article concludes with a discussion of diagnosis that provides specific guidance for the clinician on how to assess a patient for possible OCD. The next two articles in this series will cover cognitive-behavioral and medication treatment in detail.

    The aim of this study was to investigate the inductive and deductive reasoning abilities of people with obsessive-compulsive disorder (OCD). Following previous research, it was predicted that people with OCD would show different abilities on inductive reasoning tasks but similar abilities to controls on deductive reasoning tasks. A two-group comparison was used with both groups matched on a range of demographic variables. Where appropriate, unmatched variables were entered into the analyses as covariates. Twenty-three people with OCD and 25 control participants were assessed on two tasks: an inductive reasoning task (the 20-questions task) and a deductive reasoning task (a syllogistic reasoning task with a content-neutral and content-emotional manipulation). While no group differences emerged on several of the parameters of the inductive reasoning task, the OCD group did differ on one, and arguably the most important, parameter by asking fewer correct direct-hypothesis questions. The syllogistic reasoning task results were analysed using both correct response and conclusion acceptance data. While no main effects of group were evident, significant interactions indicated important differences in the way the OCD group reasoned with content neutral and emotional syllogisms. It was argued that the OCD group's patterns of response on both tasks were characterized by the need for more information, states of uncertainty, and doubt and postponement of a final decision.

    The current study examined the validity of using comorbid obsessive-compulsive personality disorder (OCPD) to identify a subtype of individuals with obsessive-compulsive disorder (OCD). Data for the current study were drawn from an ongoing, longitudinal study of the course of OCD and include intake assessments for 238 subjects with primary and current DSM-IV OCD who were treatment seeking. More than one fourth of the subjects (N=65, 27%) met criteria for comorbid OCPD. As compared to OCD-OCPD subjects, the OCD+OCPD subjects had a significantly younger age at onset of first OC symptoms (p=0.013), and a higher rate of symmetry and hoarding obsessions, and cleaning, ordering, repeating, and hoarding compulsions (all p'sOCPD had higher rates of comorbid anxiety disorders (p=0.007) and avoidant personality disorder (p=0.006). The OCD+OCPD subjects also had significantly lower ratings of global functioning (p=0.001) and more impaired social functioning (p=0.004), despite a lack of significant differences on overall severity of OCD symptoms. Our findings indicate that individuals with both OCD and OCPD have distinct clinical characteristics in terms of age at onset of initial OC symptoms, the types of obsessions and compulsions they experience, and psychiatric comorbidity. Our findings, coupled with data from family studies showing a higher than expected frequency of OCPD in first degree relatives of OCD probands, suggest that OCD associated with OCPD may represent a specific subtype of OCD. Additional research is warranted to further establish the validity of this subtype.

The burden of obsessive compulsive disorder (OCD may lead persons with diagnosed or undiagnosed OCD, and their relatives, to search for good quality information on the Web. This study aimed to evaluate the quality of Web-based information on English-language sites dealing with OCD and to compare the quality of websites found through a general and a medically specialized search engine. Methods: Keywords related to OCD were entered into Google and OmniMedicalSearch. Websites were assessed on the basis of accountability, interactivity, readability, and content quality. The "Health on the Net" (HON quality label and the Brief DISCERN scale score were used as possible content quality indicators. Of the 235 links identified, 53 websites were analyzed. Results: The content quality of the OCD websites examined was relatively good. The use of a specialized search engine did not offer an advantage in finding websites with better content quality. A score ≥16 on the Brief DISCERN scale is associated with better content quality. Conclusion: This study shows the acceptability of the content quality of OCD websites. There is no advantage in searching for information with a specialized search engine rather than a general one. Practical implications: The Internet offers a number of high quality OCD websites. It remains critical, however, to have a provider–patient talk about the information found on the Web. Keywords: Internet, quality indicators, anxiety disorders, OCD, search engine

    Full Text Available Attention is an important factor in information processing; obsessive- compulsive disorder (OCD and generalized anxiety disorder (GAD are two main emotional disorders with a chronic course. This research examined the relationship among attentional control and intrusive thoughts (worry, rumination and obsession in these disorders. It was hypothesized that attentional control is a common factor in OCD and GAD. In addition, we compared worry, rumination and obsession among OCD, GAD and non- clinical participants.The research sample included three groups: OCD (n = 25, GAD (n = 30 and non- clinical samples (n = 56. Data were collected using the Attentional Control Scale (ACS, Rumination Response Scale (RRS, Pennsylvania State Worry Questionnaire (PSWQ, Beck Depression Inventory (BDI, Beck Anxiety Inventory (BAI, Obsessive-Compulsive Inventory-Revised (OCI-R and General Health Questionnaire (GHQ-28. Data were analyzed using MANOVA and MANCOVA by SPSS-17.Multivariate Analysis of Variance revealed that the OCD and GAD groups reported greater deficits in attentional control, higher obsessive-compulsive symptoms, rumination, worry, anxiety and depression compared to the control group.This research indicated a great attentional deficit in obsessive- compulsive disorder and generalized anxiety disorder. However, no significant difference was found between these two disorders.

  6. Cognitive inflexibility in Obsessive-Compulsive Disorder.

    Gruner, Patricia; Pittenger, Christopher

    2017-03-14

    Obsessive-Compulsive Disorder (OCD) is characterized by maladaptive patterns of repetitive, inflexible cognition and behavior that suggest a lack of cognitive flexibility. Consistent with this clinical observation, many neurocognitive studies suggest behavioral and neurobiological abnormalities in cognitive flexibility in individuals with OCD. Meta-analytic reviews support a pattern of cognitive inflexibility, with effect sizes generally in the medium range. Heterogeneity in assessments and the way underlying constructs have been operationalized point to the need for better standardization across studies, as well as more refined overarching models of cognitive flexibility and executive function (EF). Neuropsychological assessments of cognitive flexibility include measures of attentional set shifting, reversal and alternation, cued task-switching paradigms, cognitive control measures such as the Trail-Making and Stroop tasks, and several measures of motor inhibition. Differences in the cognitive constructs and neural substrates associated with these measures suggest that performance within these different domains should be examined separately. Additional factors, such as the number of consistent trials prior to a shift and whether a shift is explicitly signaled or must be inferred from a change in reward contingencies, may influence performance, and thus mask or accentuate deficits. Several studies have described abnormalities in neural activation in the absence of differences in behavioral performance, suggesting that our behavioral probes may not be adequately sensitive, but also offering important insights into potential compensatory processes. The fact that deficits of moderate effect size are seen across a broad range of classic neuropsychological tests in OCD presents a conceptual challenge, as clinical symptomatology suggests greater specificity. Traditional cognitive probes may not be sufficient to delineate specific domains of deficit in this and other

    This study tested the hypothesis that people with obsessive-compulsive disorder (OCD) show an inductive reasoning style distinct from people with generalized anxiety disorder (GAD) and from participants in a non-anxious (NA) control group. The experimental procedure consisted of administering a range of six deductive and inductive tasks and a probabilistic task in order to compare reasoning processes between groups. Recruitment was in the Montreal area within a French-speaking population. The participants were 12 people with OCD, 12 NA controls and 10 people with GAD. Participants completed a series of written and oral reasoning tasks including the Wason Selection Task, a Bayesian probability task and other inductive tasks, designed by the authors. There were no differences between groups in deductive reasoning. On an inductive "bridging task", the participants with OCD always took longer than the NA control and GAD groups to infer a link between two statements and to elaborate on this possible link. The OCD group alone showed a significant decrease in their degree of conviction about an arbitrary statement after inductively generating reasons to support this statement. Differences in probabilistic reasoning replicated those of previous authors. The results pinpoint the importance of examining inference processes in people with OCD in order to further refine the clinical applications of behavioural-cognitive therapy for this disorder.

  8. The presence of magical thinking in obsessive compulsive disorder.

    2004-05-01

    Two research groups have raised the possibility that magical ideation may be a fundamental feature of obsessive-compulsive disorder. It has been proposed to underlie thought action fusion and superstitious beliefs. In this study, the Magical Ideation scale, the Lucky Behaviours and Lucky Beliefs scales, the Thought Action Fusion-Revised scale, the Padua Inventory, and the Obsessive Compulsive Inventory-Short Version were completed by 60 obsessive compulsive patients at a hospital clinic. Of all the measures, the Magical Ideation (MI) scale was found to be the most strongly related to obsessive compulsive symptoms. Large and significant relationships between MI scores and the measures of OCD were obtained even when alternative constructs (Lucky Behaviours, Lucky Beliefs, Thought Action Fusion-Revised scales) were held constant. No other variable remained significantly related to the Obsessive Compulsive Inventory-Short Version when magical ideation scores were held constant. The findings suggest that a general magical thinking tendency may underpin previous observed links between superstitiousness, thought action fusion and OCD severity.

    Tourette syndrome (TS) and obsessive-compulsive disorder (OCD) both are neuropsychiatric disorders associated with abnormalities in dopamine neurotransmission. Aims of this study were to quantify striatal D2/3 receptor availability in TS and OCD, and to examine dopamine release and symptom severity changes in both disorders following amphetamine challenge. Changes in [(11)C]raclopride binding potential (BP(ND)) were assessed using positron emission tomography before and after administration of d-amphetamine (0.3 mg kg(-1)) in 12 TS patients without comorbid OCD, 12 OCD patients without comorbid tics, and 12 healthy controls. Main outcome measures were baseline striatal D2/3 receptor BP(ND) and change in BP(ND) following amphetamine as a measure of dopamine release. Voxel-based analysis revealed significantly decreased baseline [(11)C]raclopride BP(ND) in bilateral putamen of both patient groups vs. healthy controls, differences being more pronounced in the TS than in the OCD group. Changes in BP(ND) following amphetamine were not significantly different between groups. Following amphetamine administration, tic severity increased in the TS group, which correlated with BP(ND) changes in right ventral striatum. Symptom severity in the OCD group did not change significantly following amphetamine challenge and was not associated with changes in BP(ND). This study provides evidence for decreased striatal D2/3 receptor availability in TS and OCD, presumably reflecting higher endogenous dopamine levels in both disorders. In addition, it provides the first direct evidence that ventral striatal dopamine release is related to the pathophysiology of tics. Copyright © 2013 Elsevier B.V. and ECNP. All rights reserved.

    To compare patterns of temperament and character and the prevalence of Obsessive-Compulsive Personality Disorder (OCPD) and OCPD traits in parents of children with OCD and parents of healthy controls. TCI and SCID-II were administered to 63 parents of 32 children with OCD and 63 parents of age- and sex-matched controls with no psychiatric diagnosis. Interviewers were not blind to proband status. Personality dimension scores and frequencies of OCPD criteria in both groups were compared after excluding parents with a diagnosis of OCD. Relationships between TCI dimensions and OCPD symptoms in parents and the clinical characteristics of OCD children were also studied. Parents of OCD children presented significantly higher scores in harm avoidance and lower scores in self-directedness, cooperativeness and reward dependence than parents of healthy children. A higher incidence of OCPD was found in parents of probands (pOCPD criteria in these parents in comparison to parents of healthy children highlight the importance of the role of personality factors in familial OCD.

    Surgical therapies for treatment-refractory obsessive-compulsive disorder (OCD), such as deep brain stimulation or psychosurgery, remain unattainable for many patients. Despite the long-held view that electroconvulsive therapy (ECT) is an ineffective treatment for OCD, there is no systematic review to support or refute this claim, which is the basis of the current review. A systematic search of MEDLINE, Web of Science, Scopus, and LILACS databases was conducted on December 22, 2013, using the terms obsessive-compulsive disorder and electroconvulsive therapy. Reference lists, specific journals, and clinical trial registries were also scrutinized. No date or language limitation was imposed on the search. After irrelevant and redundant records from the 500 identified titles were excluded, the 50 articles reporting the acute treatment effects of ECT in OCD and related constructs (involving a total of 279 patients) were analyzed for this study. The relevant sociodemographic, clinical, and outcome data of individual cases were extracted. Data from individual cases were used to compare the characteristics of responders versus nonresponders to ECT. Most selected records were case reports/series; there were no randomized controlled trials. A positive response was reported in 60.4% of the 265 cases in which individual responses to ECT were available. ECT responders exhibited a significantly later onset of OCD symptoms (P = .003), were more frequently nondepressed (P = .009), more commonly reported being treated with ECT for severe OCD (P = .01), and received a fewer number of ECT sessions (P = .03). ECT responders were also less frequently previously treated with adequate trials of serotonin reuptake inhibitors (P = .05) and cognitive-behavioral therapy (P = .005). Although 60% of the reported cases reviewed exhibited some form of a positive response to ECT, it cannot be stated that this provides evidence that ECT is indeed effective for OCD. © Copyright 2015 Physicians

    Three to four million individuals struggle with obsessive-compulsive disorder (OCD) in the United States at any given time. OCD can be a debilitating disorder associated with significant quality-of-life and occupational impairment. First-line treatments for OCD (selective serotonin reuptake inhibitors and exposure and response prevention therapy) have been shown to be effective; yet, many individuals suffering from OCD experience multiple barriers to accessing these treatments. In fact, it can take as many as 17 years from onset of symptoms to effective treatment. Given the need to increase access to and utilization of effective treatments, direct-to-consumer marketing in the context of OCD appears crucial. The International OCD Foundation (formerly the Obsessive Compulsive Foundation) was established as a nonprofit organization with a mission to educate the public and mental health professionals about appropriate practice guidelines, raise awareness of the disorder, and ensure that individuals looking for treatment find the necessary resources. This paper reviews the obstacles those struggling with OCD face in their attempts to alleviate suffering, as well as the direct-to-consumer strategies and tactics used by the International OCD Foundation to improve access to empirically supported, effective treatment.

    In the past twenty years functional brain imaging has advanced to the point of tackling the differential diagnosis, prognosis and therapeutic response in Neurology and Psychiatry. Psychiatric disorders were rendered 'functional' a century ago; however nowadays they can be seen by means of brain imaging. Functional images in positron emission tomography (PET) and single photon emission tomography (NEUROSPET) show in non-invasive fashion the state of brain functioning. PET does this assessing glucose metabolism and NEUROSPET by putting cerebral blood flow in images. Prevalence of OCD is clearly low (2 to 3%), but comorbidity with depression, psychoses, bipolar disorder and schizophrenia is high. Furthermore, it is not infrequent with autism, attention disorder, tichotillomany, borderline personality disorders, in pathological compulsive spending, sexual compulsion and in pathological gambling, in tics, and in Gilles de la Tourette disorder, NEUROSPET and PET show hypoperfusion in both frontal lobes, in their prefrontal dorsolateral aspects, in their inferior zone and premotor cortex, with hyperperfusion in the posterior cingulum and hypoperfusion in basal ganglia (caudate nucleus). Cummings states that hyperactivity of the limbic system might be involved in OCD. Thus, brain imaging in OCD is a diagnostic aid, allows us to see clinical imagenological evolution and therapeutic response and, possibly, it is useful predict therapeutic response (Au)

    Some studies have shown that children and adolescents with obsessive-compulsive disorder (OCD) and co-morbid tics differ from those without co-morbid tics in terms of several demographic and clinical characteristics. However, not all studies have confirmed these differences. This study examined children and adolescents with OCD and with possible or definite tic specifiers according to the DSM-5 in order to see whether they differ from patients without any tic symptoms regarding clinical presentation and outcome of cognitive behavioral therapy (CBT). The full sample included 269 patients (aged 7-17) with primary DSM-IV OCD who had participated in the Nordic Long-term Treatment Study (NordLOTS). Symptoms of tics were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). One or more tic symptoms were found in 29.9% of participants. Those with OCD and co-morbid tic symptoms were more likely male, more likely to have onset of OCD at an earlier age, and differed in terms of OCD symptom presentation. More specifically, such participants also showed more symptoms of OCD-related impairment, externalization, autism spectrum disorder (ASD), social anxiety, and attention-deficit/hyperactivity disorder (ADHD). However, the two groups showed no difference in terms of OCD severity or outcome of CBT. Children and adolescents with OCD and co-morbid tic symptoms differ from those without tic symptoms in several aspects of clinical presentation, but not in their response to CBT. Our results underscore the effectiveness of CBT for tic-related OCD. Nordic Long-term Obsessive-Compulsive Disorder (OCD) Treatment Study; www.controlled-trials.com ; ISRCTN66385119.

    Obsessive-compulsive disorder is a common and often chronic psychiatric illness that significantly interferes with the patient´s functioning and quality of life. The disorder is characterized by excessive intrusive and inappropriate anxiety evoking thoughts as well as time consuming compulsions that cause significant impairment and distress. The symptoms are often accompanied by shame and guilt and the knowledge of the general public and professional community about the disorder is limited. Hence it is frequently misdiagnosed or diagnosed late. There are indications that the disorder is hereditary and that neurobiological processes are involved in its pathophysiology. Several psychological theories about the causes of obsessive-compulsive disorder are supported by empirical evidence. Evidence based treatment is either with serotoninergic medications or cognitive behavioral therapy, particularly a form of behavioral therapy called exposure response prevention. Better treatment options are needed because almost a third of people with obsessive-compulsive disorder respond inadequatly to treatment. In this review article two cases of obsessive-compulsive disorder are presented. The former case is a young man with typical symptoms that respond well to treatment and the latter is a middle aged lady with severe treatment resistant symptoms. She underwent stereotactic implantation of electrodes and received deep brain stimulation, which is an experimental treatment for severe obsessive-compulsive disorder that does not respond to any conventional treatment.

    The aim of the study is to evaluate the relationship between obsessive-compulsive disorder (OCD) symptoms and dissociative experiences and the effect of childhood traumatic experiences on this relationship in OCD patients. Fifty consecutive OCD patients and 50 healthy controls are enrolled for this study. Sociodemographic and Clinical Data Form, Dissociative Experiences Scale (DES), Padua Inventory (PI) and Childhood Trauma Questionnaire (CTQ) are applied to participants. Average DES total score in the patient group is 20.58 and in the control group it is 4.87. In the patient group, when we evaluate the relation strengths of DES total and subscale scores with PI total score, we found out that amnesia subscale has r=0.361 ( p controls. Among dissociative experiences, absorption has stronger relation with OCD symptoms. The relation between OCD and dissociation is independent from and stronger than the relation between childhood traumatic experiences and OCD.

    Family accommodation describes ways in which parents modify their behavior to help a child avoid or alleviate distress caused by emotional disorders. Accommodation is associated with increased symptom severity, lower functioning, and poorer treatment outcomes. Accommodation is prevalent in childhood obsessive-compulsive disorder (OCD) and anxiety disorders (ADs) but no studies have compared accommodation in these groups or compared them to healthy controls to ascertain if accommodation is prevalent in the general population. This study addresses these gaps by comparing patterns of accommodation, factors that maintain accommodation, and its relation to symptom severity in OCD and AD, relative to healthy controls. We directly compared reports of accommodation to childhood OCD (N = 26) and AD (N = 31), and a comparison group of nonanxious (NA) children (N = 30). Mothers completed measures of accommodation (Family Accommodation Scale (FAS)/Family Accommodation Scale-Anxiety (FASA)), anxiety (Screen for Childhood Anxiety Related Emotional Disorders-Parent Report (SCARED-PR)), and OCD (Children's Yale-Brown Obsessive Compulsive Scale (CYBOCS)). Family accommodation is prevalent among mothers of children with OCD and AD. Few differences were found between the two clinical groups who reported more accommodation (F[2,84] = 23.411, P anxiety in AD (r = .426, P = .017) and OCD (r = .465, P = .017), but not in the NA group. Findings highlight family accommodation as a phenomenon that applies broadly and in a similar manner to children with AD and OCD. Evaluating accommodation provides useful information for clinical care and is an important part of the assessment of children with AD and OCD. © 2014 Wiley Periodicals, Inc.

    Full Text Available BACKGROUND: Pathological gambling (PG and obsessive-compulsive disorder (OCD are conceptualized as a behavioral addiction, with a dependency on repetitive gambling behavior and rewarding effects following compulsive behavior, respectively. However, no neuroimaging studies to date have examined reward circuitry during the anticipation phase of reward in PG compared with in OCD while considering repetitive gambling and compulsion as addictive behaviors. METHODS/PRINCIPAL FINDINGS: To elucidate the neural activities specific to the anticipation phase of reward, we performed event-related functional magnetic resonance imaging (fMRI in young adults with PG and compared them with those in patients with OCD and healthy controls. Fifteen male patients with PG, 13 patients with OCD, and 15 healthy controls, group-matched for age, gender, and IQ, participated in a monetary incentive delay task during fMRI scanning. Neural activation in the ventromedial caudate nucleus during anticipation of both gain and loss decreased in patients with PG compared with that in patients with OCD and healthy controls. Additionally, reduced activation in the anterior insula during anticipation of loss was observed in patients with PG compared with that in patients with OCD which was intermediate between that in OCD and healthy controls (healthy controls < PG < OCD, and a significant positive correlation between activity in the anterior insula and South Oaks Gambling Screen score was found in patients with PG. CONCLUSIONS: Decreased neural activity in the ventromedial caudate nucleus during anticipation may be a specific neurobiological feature for the pathophysiology of PG, distinguishing it from OCD and healthy controls. Correlation of anterior insular activity during loss anticipation with PG symptoms suggests that patients with PG fit the features of OCD associated with harm avoidance as PG symptoms deteriorate. Our findings have identified functional disparities and

    Obsessive-compulsive disorder (OCD) is a complex and severe psychiatric disorder whose pathogenesis is not fully understood. Recent studies have shown white matter (WM) alterations in adults with OCD, but the results have been inconsistent. The present study investigated WM structure in OCD patients with the hypothesis that large-scale brain networks may be disrupted in OCD. A total of 24 patients with OCD and 23 healthy controls (HCs) were scanned with diffusion tensor imaging. A tract-based spatial statistics (TBSS) approach was used to detect differences across the whole brain in patients with OCD vs HCs; post hoc fiber tractography was applied to characterize developmental differences between the two groups. Relative to HCs, patients with OCD had lower fractional anisotropy (FA) values in the corpus callosum (CC), left anterior corona radiata (ACR), left superior corona radiata (SCR) and left superior longitudinal fasciculus (SLF), and higher radial diffusivity in the genu and body of CC. Among the TBSS de-projected region of interest results, compared with HCs, patients with OCD showed lower of the mean FA values of fiber bundles passing though the SLF, and shorter lengths of ACR, SCR and CC. In conclusion, this study provides novel evidence of widespread microstructural alterations in OCD and suggests that OCD may involve abnormalities affecting a broader network of regions than commonly believed.

    Full Text Available Umberto Albert, Alessandra Baffa, Giuseppe Maina Rita Levi Montalcini Department of Neuroscience, A.O.U. San Luigi Gonzaga, University of Turin, Turino, Italy Abstract: The term accommodation has been used to refer to family responses specifically related to obsessive–compulsive (OC symptoms: it encompasses behaviors such as directly participating in compulsions, assisting a relative with obsessive–compulsive disorder (OCD when he/she is performing a ritual, or helping him/her to avoid triggers that may precipitate obsessions and compulsions. At the opposite side, family responses to OCD may also include interfering with the rituals or actively opposing them; stopping accommodating OC symptoms or actively interfering with their performance is usually associated with greater distress and sometimes even with aggressive behaviors from the patients. This article summarizes progress of the recent research concerning family accommodation in relatives of patients with OCD. Family accommodation is a prevalent phenomenon both among parents of children/adolescents with OCD and relatives/caregivers of adult patients. It can be measured with a specific instrument, the Family Accommodation Scale, of which there are several versions available for use in clinical practice. The vast majority of both parents of children/adolescents with OCD and family members of adult patients show at least some accommodation; providing reassurances to obsessive doubts, participating in rituals and assisting the patient in avoidance are the most frequent accommodating behaviors displayed by family members. Modification of routine and modification of activities specifically due to OC symptoms have been found to be equally prevalent. Specific characteristics of patients (such as contamination/washing symptoms and of relatives (the presence of anxiety or depressive symptoms or a family history positive for another anxiety disorder are associated with a higher degree of family

    Full Text Available Anxiety disorders have been linked to a hyperactivated cortico-amygdalar circuitry. Recent findings highlight the amygdala's role in mediating elevated anxiety in obsessive–compulsive disorder (OCD. However, modulation of amygdala hyperactivation by attentional distraction – an effective emotion regulation strategy in healthy individuals – has not yet been examined. While undergoing functional magnetic resonance imaging twenty-one unmedicated OCD patients and 21 controls performed an evaluation and a distraction task during symptom provocation with individually tailored OCD-relevant pictures. To test the specificity of responses, additional aversive and neutral stimuli were included. Significant group-by-picture type interactions were observed within fronto–striato–limbic circuits including the amygdala. In these regions patients showed increased BOLD responses during processing of OCD triggers relative to healthy controls. Amygdala hyperactivation was present across OCD symptom dimensions indicating that it represents a common neural correlate. During distraction, we observed dampening of patients' amygdala hyperactivity to OCD-relevant stimuli. Augmented amygdala involvement in patients during symptom provocation, present across OCD symptom dimensions, might constitute a correlate of fear expression in OCD linking it to other anxiety disorders. Attentional distraction seemed to dampen emotional processing of disorder-relevant stimuli via amygdala downregulation. The clinical impact of this strategy to manage anxiety in OCD should be further elucidated.

    Obsessive-compulsive disorder (OCD) is phenomenologically heterogeneous, and findings of underlying structure classification based on symptom grouping have been ambiguous to date. Variable-centered approaches, primarily factor analysis, have been used to identify homogeneous groups of symptoms; but person-centered latent methods have seen little use. This study was designed to uncover sets of homogeneous groupings within 1611 individuals with OCD based on symptoms. Latent class analysis models using 61 obsessive-compulsive symptoms collected from the Yale-Brown Obsessive-Compulsive Scale were fit. Relationships between latent class membership and treatment response, sex, symptom severity, and comorbid tic disorders were tested for relationship to class membership. Latent class analysis models of best fit yielded 3 classes. Classes differed only in frequency of symptom endorsement. Classes with higher symptom endorsement were associated with earlier age of onset, being male, higher Yale-Brown Obsessive-Compulsive Scale symptom severity scores, and comorbid tic disorders. There were no differences in treatment response between classes. These results provide support for the validity of a single underlying latent OCD construct, in addition to the distinct symptom factors identified previously via factor analyses.

    Comorbidity of obsessive-compulsive disorder (OCD) with other mental disorders has been demonstrated repeatedly. Few longitudinal studies, however, have evaluated the temporal association of prior OCD and subsequent mental disorders across the age period of highest risk for first onset of mental disorders. We examined associations between prior OCD and a broad range of subsequent mental disorders and simulated proportions of new onsets of mental disorders that could potentially be attributed to prior OCD, assuming a causal relationship. Data from 3,021 14- to 24-year-old community subjects were prospectively collected for up to 10 years. DSM-IV OCD and other DSM-IV mental disorders were assessed with the Munich-Composite International Diagnostic Interview. We used adjusted time-dependent proportional hazard models to estimate the temporal associations of prior OCD with subsequent mental disorders. Prior OCD was associated with an increased risk of bipolar disorders (BIP; [hazard ratio, HR = 6.9, 95% confidence interval, CI, (2.8,17.3)], bulimia nervosa [HR = 6.8 (1.3,36.6)], dysthymia [HR = 4.4 (2.1,9.0)], generalized anxiety disorder (GAD; [HR = 3.4 (1.1,10.9)], and social phobia [HR = 2.9 (1.1,7.7)]). Of these outcome disorders, between 65 and 85% could be attributed to OCD in the exposed group, whereas between 1.5 and 7.7% could be attributed to OCD in the total sample. This study provides strong evidence that prior OCD is associated with an increased risk of subsequent onset of BIP, bulimia nervosa, dysthymia, GAD, and social phobia among adolescents and young adults. Future studies should evaluate if early treatment of OCD can prevent the onset of these subsequent mental disorders. © 2018 Wiley Periodicals, Inc.

    Full Text Available Introduction: Obsessive-compulsive disorder (OCD, even if the patient’s obsession content is not related to sexuality, may be a problem in the sexual lives of individuals. In this article, sexual function in obsessive compulsive disorder patients is discussed based on an OCD case. Case: Male 36 years old and female 32 years old couple. Man had complaints of lack of control of ejaculation and woman had complaints of lack of orgasm. Man was diagnosed with premature ejaculation and woman was diagnosed with aversion and anorgasmia according to DSM-IV (Diagnostic and Statistical Manual Of Mental Disorders criteria. During therapy, the female patient was diagnosed with OCD as well. Loss of control was not acceptable to the patient. Thus she was avoiding from exhilarating stimuli. After cognitive restructuring of her evaluations about control, sex therapy was continued. At the end of the therapy the avoidance of the patient disappeared and anorgasmia was treated and ejeculation time of the male patient was 15 minutes. Conclusion: Sexual dysfunction is a common problem in patients with OCD. Patient may have avoidance that may adversely affect her sexuality. If a patient has avoidance about sexuality, the reason of this avoidance may or may not be the usual and expected thought content like avoidance of contamination. The evaluations of OCD patients about control may also adversely affect their sexuallity. The thought leading to avoidance behavior, may vary from patient to patient. However, to identify these thoughts with cognitive interventions and work with them will improve.the patient.

    Obsessive compulsive symptoms are commonly reported in those with schizophrenia. Clozapine has previously been reported to induce, aggravate and alleviate these symptoms. It is unclear if these are similar to the symptoms experienced by those with obsessive compulsive disorder. This study describes the obsessive compulsive symptom profile of a population of patients with schizophrenia treated with clozapine (n = 62) and compares this with patients with Obsessive Compulsive Disorder (n = 35). All participants were attending an outpatient community mental health service. The Obsessive Compulsive Inventory (which measures the frequency and associated distress of a range of "behavioural" and "cognitive" symptoms), the Hospital Anxiety and Depression Scale and a demographic questionnaire were completed. In addition the schizophrenia group treated with clozapine completed the Brief Psychiatric Rating Scale. The OCD group reported significantly more symptoms for all OCI subscales compared to the clozapine group. Overall fourteen (22%) of the schizophrenia treated with clozapine group had clinically significant total OCI scores. Two (3%) had documented OCS pre clozapine. De novo OCS was reported in twelve (19%) cases. Nine (11%) had documented OC symptoms pre-clozapine while only two (3%) had symptoms after clozapine was initiated. In terms of OC symptom profile, the clozapine group scored highest on the Doubting scale, a cognitive symptom whereas the OCD group scored highest on Washing, a behavioural symptom. Both groups reported greater distress with cognitive rather than behavioural symptoms. Medication including clozapine dose was not correlated with symptom severity. Anxiety correlated highly with obsessive compulsive symptoms in the Clozapine group but not the OCD group. Within the Clozapine group, Obsessing correlated highly with Unusual Thought Content. Findings suggest that obsessive compulsive symptoms in the Clozapine group may reflect a subtype of \\'schizo

    Pediatric obsessive-compulsive disorder (OCD) and tic disorders (TD) are often associated with attention-deficit hyperactivity disorder (ADHD). In order to clarify the role of attention and inhibitory control in pediatric OCD and TD, a continuous performance test (CPT) was administered to a cohort of children and adolescents with OCD alone, TD alone, and OCD+TD. A clinical cohort of 48 children and adolescents with OCD alone (n=20), TD alone (n=15), or OCD+TD (n=13) was interviewed clinically and administered the Conners Continuous Performance Test II (CPT-II). The Conners CPT-II is a 14-minute normed computerized test consisting of 6 blocks. It taps into attention, inhibitory control, and sustained attention cognitive domains. Key parameters include errors of omission (distractability), commission (inhibitory control), and variable responding over time (sustained attention). Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) criteria were applied in a best-estimate process to diagnose OCD, TD, ADHD, and anxiety disorders. Children with OCD+TD had more errors of omission (p=0.03), and more hit RT block change (p=0.003) and hit SE block change (p=0.02) than subjects with OCD alone and TD alone. These deficits in sustained attention were associated with younger age and hoarding tendencies. A clinical diagnosis of ADHD in the OCD+TD group also determined worse sustained attention. A deficit in sustained attention, a core marker of ADHD, is also a marker of OCD+TD, compared to OCD alone and TD alone. Biological correlates of sustained attention may serve to uncover the pathophysiology of OCD and TD through genetic and imaging studies.

    Full Text Available OBJECTIVE: This study aims to evaluate the process of decision-making in patients with obsessive-compulsive disorder (OCD using the Iowa Gambling Task (IGT. In addition, we intend to expand the understanding of clinical and demographic characteristics that influence decision-making. METHOD: Our sample consisted of 214 subjects (107 diagnosed with OCD and 107 healthy controls who were evaluated on their clinical, demographic and neuropsychological features. Moreover, the Iowa Gambling Task (IGT, a task that detects and measures decision-making impairments, was used. RESULTS: We found that OCD patients performed significantly worse on the IGT. Furthermore, features such as symptoms of anxiety did not influence IGT performance. CONCLUSION: Impaired decision-making seems to be a key feature of OCD. Given that OCD is a complex heterogeneous disorder, homogeneous groups are necessary for an accurate characterization of our findings.

    Thought-action fusion (TAF) is a cognitive bias presumed to underlie the development of obsessional problems (i.e. obsessive-compulsive disorder; OCD). Previous studies have found that TAF is related to not only OCD, but also to other anxiety disorders. In the present study we compared levels of TAF in OCD patients and in patients with other anxiety disorders, depression, and healthy controls to examine whether TAF is characteristic of individuals with emotional distress in general, as opposed to anxiety disorders per se. We also examined whether negative affect (i.e. anxiety and depression) mediates the relationship between OCD and TAF. Results indicated that OCD patients were characterized by higher scores on likelihood-self and likelihood-other TAF, but that this difference was predominately due to differences in negative affect. These findings support a model in which negative affect mediates the relationship between OCD and TAF.

    Full Text Available Abstract Background Cognitive behavior therapy (CBT is widely regarded as an effective treatment for obsessive compulsive disorder (OCD, but access to CBT therapists is limited. Internet-based CBT (ICBT with therapist support is a way to increase access to CBT but has not been developed or tested for OCD. The aim of this study was to evaluate ICBT for OCD. Method An open trial where patients (N = 23 received a 15-week ICBT program with therapist support consisting of psychoeducation, cognitive restructuring and exposure with response prevention. The primary outcome was the Yale-Brown Obsessive Compulsive Scale (Y-BOCS, which was assessed by a psychiatrist before and immediately after treatment. Secondary outcomes were self-rated measures of OCD symptoms, depressive symptoms, general functioning, anxiety and quality of life. All assessments were made at baseline and post-treatment. Results All participants completed the primary outcome measure at all assessment points. There were reductions in OCD symptoms with a large within-group effect size (Cohen's d = 1.56. At post-treatment, 61% of participants had a clinically significant improvement and 43% no longer fulfilled the diagnostic criteria of OCD. The treatment also resulted in statistically significant improvements in self-rated OCD symptoms, general functioning and depression. Conclusions ICBT with therapist support reduces OCD symptoms, depressive symptoms and improves general functioning. Randomized trials are needed to confirm the effectiveness of this new treatment format. Trial Registration ClinicalTrials.gov: NCT01348529

    Lower performance on memory tests in obsessive-compulsive disorder (OCD) has been repeatedly observed. However, the origins of these performance deficits are not sufficiently explained. In this study we tested if OCD-related extensive focus of attention on thoughts (heightened self-consciousness) could be an explanatory mechanism for lower memory performance. Heightened situational self-consciousness was manipulated by instructing participants to either monitor neutral thoughts or to monitor OCD-related thoughts. We included a Behavioral Avoidance Task based on individual obsessions and compulsions to induce OCD-related thoughts. Participants were asked to perform these monitoring tasks in parallel to a taxing verbal memory task, resulting in learning under divided attention. The two conditions of learning under divided attention were compared to a single-task condition. Twenty-four participants with OCD and 24 healthy controls took part in these three learning conditions. The results indicate that in both groups memory performance deteriorated in the two conditions with divided attention compared to the single task condition. In the OCD-related thought monitoring condition (OTM) self-consciousness and Behavioral Avoidance Task-induced stress and fear were particularly increased and memory performance further deteriorated in the OCD group. This finding highlights an important and underestimated mechanism (personal involvement) which might serve to better understand lower memory performance in OCD. Copyright © 2017 Elsevier Ltd.

    Obsessive-compulsive disorder (OCD) and Tourette's syndrome are highly heritable neurodevelopmental disorders that are thought to share genetic risk factors. However, the identification of definitive susceptibility genes for these etiologically complex disorders remains elusive. The authors report a combined genome-wide association study (GWAS) of Tourette's syndrome and OCD. The authors conducted a GWAS in 2,723 cases (1,310 with OCD, 834 with Tourette's syndrome, 579 with OCD plus Tourette's syndrome/chronic tics), 5,667 ancestry-matched controls, and 290 OCD parent-child trios. GWAS summary statistics were examined for enrichment of functional variants associated with gene expression levels in brain regions. Polygenic score analyses were conducted to investigate the genetic architecture within and across the two disorders. Although no individual single-nucleotide polymorphisms (SNPs) achieved genome-wide significance, the GWAS signals were enriched for SNPs strongly associated with variations in brain gene expression levels (expression quantitative loci, or eQTLs), suggesting the presence of true functional variants that contribute to risk of these disorders. Polygenic score analyses identified a significant polygenic component for OCD (p=2×10(-4)), predicting 3.2% of the phenotypic variance in an independent data set. In contrast, Tourette's syndrome had a smaller, nonsignificant polygenic component, predicting only 0.6% of the phenotypic variance (p=0.06). No significant polygenic signal was detected across the two disorders, although the sample is likely underpowered to detect a modest shared signal. Furthermore, the OCD polygenic signal was significantly attenuated when cases with both OCD and co-occurring Tourette's syndrome/chronic tics were included in the analysis (p=0.01). Previous work has shown that Tourette's syndrome and OCD have some degree of shared genetic variation. However, the data from this study suggest that there are also distinct

    Previous studies have shown differences in clinical features of obsessive-compulsive disorder (OCD) between men and women, including mean age at onset of obsessive-compulsive symptoms (OCS), types of OCS, comorbid disorders, course, and prognosis. The aim of this study was to compare male and female Brazilian patients with OCD on several demographic and clinical characteristics. Three hundred thirty outpatients with OCD (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition [DSM-IV], criteria) who sought treatment at 3 Brazilian public universities and at 2 private practice clinics in the city of São Paulo were evaluated. The assessment instruments used were the Yale-Brown Obsessive-Compulsive Scale to evaluate OCD severity and symptoms, the Beck Depression and Anxiety Inventories, the Yale Global Tic Severity Scale, and the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I Disorders to assess psychiatric comorbidity. Fifty-five percent of the patients (n = 182) were men who were significantly more likely than women to be single and to present sexual, religious, and symmetry obsessions and mental rituals. They also presented earlier onset of OCS and earlier symptom interference in functioning, and significantly more comorbid tic disorders and posttraumatic stress disorder. Women, besides showing significantly higher mean scores in the Beck Depression and Anxiety Inventories, were more likely to present comorbid simple phobias, eating disorders in general and anorexia in particular, impulse control disorders in general, and compulsive buying and skin picking in particular. No significant differences were observed between sexes concerning family history of OCS or OCD, and global symptoms severity, either in obsession or compulsive subscale. The present study confirms the presence of sex-related differences described in other countries and cultures. The fact that the OCS start earlier and

    There were demonstrated capabilities of the Memory Function Formalism (MFF) in analyzing cross correlations in human brain bioelectric activity at obsessive-compulsive disorder (OCD). To extract the information about collective phenomena in (electroencephalogram) EEG brain activity we use the power spectra of memory functions and the memory quantifiers. We discover the pairs of the electrodes with the greatest differences in dynamic and stochastic parameters for patients with the different condition. The high OCD condition is characterized by the influence of the memory effects. The MFF cross correlation analysis allow to describe the collective phenomena in EEG dynamics at OCD including the dynamic, spectral and stochastic behavior. (paper)

    Obsessive compulsive disorder (OCD) is associated with a moderate degree of underperformance on cognitive tests, including deficient processing speed. However, despite little research focusing on Intelligence Quotient (IQ) in OCD, it has long been speculated that the disorder is associated with elevated intellectual capacity. The present meta-analytic study was, therefore, conducted to quantitatively summarize the literature on IQ in OCD systematically. We identified 98 studies containing IQ data among individuals with OCD and non-psychiatric comparison groups, and computed 108 effect sizes for Verbal IQ (VIQ, n = 55), Performance IQ (PIQ, n = 13), and Full Scale IQ (FSIQ, n = 40). Across studies, small effect sizes were found for FSIQ and VIQ, and a moderate effect size for PIQ, exemplifying reduced IQ in OCD. However, mean IQ scores across OCD samples were in the normative range. Moderator analyses revealed no significant moderating effect across clinical and demographic indices. We conclude that, although lower than controls, OCD is associated with normative FSIQ and VIQ, and relatively lowered PIQ. These results are discussed in light of neuropsychological research in OCD, and particularly the putative impact of reduced processing speed in this population. Recommendations for utilization of IQ tests in OCD, and directions for future studies are offered.

Previous work has shown that TS and OCD have some degree of shared genetic variation. However, the data from this study suggest that there are also distinct components to the genetic architectures of TS and OCD. Furthermore, OCD with co-occurring TS/CT may have different underlying genetic susceptibility compared to OCD alone. PMID:25158072

    Obsessive-compulsive disorder (OCD) is a heterogeneous condition, comprised of multiple symptom domains. This study used aggregate composite scales representing three core OCD dimensions (Checking, Cleaning, Rituals), as well as Hoarding, to examine the discriminant validity, diagnostic specificity, and predictive ability of OCD symptom scales. The core OCD scales demonstrated strong patterns of convergent and discriminant validity – suggesting that these dimensions are distinct from other self-reported symptoms – whereas hoarding symptoms correlated just as strongly with OCD and non-OCD symptoms in most analyses. Across analyses, our results indicated that Checking is a particularly strong, specific marker of OCD diagnosis, whereas the specificity of Cleaning and Hoarding to OCD was less strong. Finally, the OCD Checking scale was the only significant predictor of OCD diagnosis in logistic regression analyses. Results are discussed with regard to the importance of assessing OCD symptom dimensions separately and implications for classification. PMID:23026094

    OBJECTIVE Anterior capsulotomy (AC) is sometimes used as a last resort for treatment-refractory obsessive-compulsive disorder (OCD). Previous studies assessing neuropsychological outcomes in patients with OCD have identified several forms of cognitive dysfunction that are associated with the disease, but few have focused on changes in cognitive function in OCD patients who have undergone surgery. In the present study, the authors investigated the effects of AC on the cognitive function of patients with treatment-refractory OCD. METHODS The authors selected 14 patients with treatment-refractory OCD who had undergone bilateral AC between 2007 and 2013, 14 nonsurgically treated OCD patients, and 14 healthy control subjects for this study. The 3 groups were matched for sex, age, and education. Several neuropsychological tests, including Similarities and Block Design, which are subsets of the Wechsler Abbreviated Scale of Intelligence; Immediate and Delayed Logical Memory and Immediate and Delayed Visual Reproduction, which are subsets of the Wechsler Memory Scale-Revised; and Corrects, Categories, Perseverative Errors, Nonperseverative Errors, and Errors, subtests of the Wisconsin Card Sorting Test, were conducted in all 42 subjects at baseline and after AC, after nonsurgical treatment, or at 6-month intervals, as appropriate. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to measure OCD symptoms in all 28 OCD patients. RESULTS The Y-BOCS scores decreased significantly in both OCD groups during the 12-month follow-up period. Surgical patients showed higher levels of improvement in verbal memory, visual memory, visuospatial skills, and executive function than the nonsurgically treated OCD patients. CONCLUSIONS The findings of this study suggest that AC not only reduces OCD symptoms but also attenuates moderate cognitive deficits.

    Obsessive--compulsive disorder (OCD) is a severe, highly prevalent and often chronically disabling illness with frequent onset in childhood and adolescence. This underscores the importance of studying the illness during childhood near the onset of illness to minimize potential confounds of long-term illness duration and treatment intervention as well as to examine the developmental underpinnings of the illness. In this review, the authors focus on an integrated series of brain-imaging studies in paediatric OCD suggesting a reversible glutamatergically mediated thalamo-cortical--striatal dysfunction in OCD and their relevance for improved diagnosis and treatment of the condition. Developmental neurobiological models for OCD are presented and particular attention is devoted to evaluating neuroimaging studies designed to test these models and how they may help predict treatment response in paediatric OCD.

    Obsessive-compulsive disorder (OCD) is a chronic and impairing condition. A very small percentage of patients become asymptomatic after treatment. The purpose of this paper was to review the alternative therapies available for OCD when conventional treatment fails. Data were extracted from controlled clinical studies (evidence-based medicine) published on the MEDLINE and Science Citation Index/Web of Science databases between 1975 and 2012. Findings are discussed and suggest that clinicians dealing with refractory OCD patients should: 1) review intrinsic phenomenological aspects of OCD, which could lead to different interpretations and treatment choices; 2) review extrinsic phenomenological aspects of OCD, especially family accommodation, which may be a risk factor for non-response; 3) consider non-conventional pharmacological approaches; 4) consider non-conventional psychotherapeutic approaches; and 5) consider neurobiological approaches.

    The cerebral metabolic rate for glucose was studied in 18 adults with childhood-onset obsessive-compulsive disorder (OCD) and in age- and sex-matched controls using positron emission tomography and fludeoxyglucose F 18. Both groups were scanned during rest, with reduced auditory and visual stimulation. The group with OCD showed an increased glucose metabolism in the left orbital frontal, right sensorimotor, and bilateral prefrontal and anterior cingulate regions as compared with controls. Ratios of regional activity to mean cortical gray matter metabolism were increased for the right prefrontal and left anterior cingulate regions in the group with OCD as a whole. Correlations between glucose metabolism and clinical assessment measures showed a significant relationship between metabolic activity and both state and trait measurements of OCD and anxiety as well as the response to clomipramine hydrochloride therapy. These results are consistent with the suggestion that OCD may result from a functional disturbance in the frontal-limbic-basal ganglia system

    We dedicated our work to study the socio-demographic aspect of obsessive compulsive disorder (OCD) patients seeking psychiatric treatment in the outpatient clinic of Hamad General Hospital for a duration of approximately 5 years of continuous follow-up. Out of 8878 individual patients who attended the psychiatric outpatient clinic of Hamad General Hospital in Qatar, during the period from August 1996 to December 2001, we reviewed a total number of 348 patients with the diagnosis of OCD (according to International Classification of Diseases-10 diagnostic criteria). We divided them according to their age, sex, nationality, duration of illness, occupation and marital status. Each patient was interviewed using a structured interview technique and evaluated by a psychiatrist in one session at the psychiatric outpatient clinic. We found that the disorder is more prevalent among non-Qatari people (52%) (Arabs 36.2%, non-Arabs 15.8%) than Qatari people (48%); more common at the age groups of 31-45 years (44.8%); more frequent in the category that visited the outpatient clinic for a period of 1-4 years (60%). We found that the married females (34.5%) are affected more than the married male patients (24.7%). It was also found that in the diagnosis of OCD predominantly obsessional thoughts were 54.9%; more frequent in the sample than the other diagnosis. In the State of Qatar, where expatriates usually outnumber Qatari patients, we discovered that non-Qatari patients are affected more with OCD than the natives. Sex, marital status and occupation also proved to be important factors. From our study, in the female married group, being a housewife seems to pose a greater risk in developing OCD. Predominantly obsessional thought was the most common sub-type of OCD affecting the patients in Qatar.

    Obsessive-compulsive disorder (OCD) is known as a clinically heterogeneous disorder characterized by symptom dimensions. Although substantial numbers of neuroimaging studies have demonstrated the presence of brain abnormalities in OCD, their results are controversial. The clinical heterogeneity of OCD could be one of the reasons for this. It has been hypothesized that certain brain regions contributed to the respective obsessive-compulsive dimensions. In this study, we investigated the relationship between symptom dimensions of OCD and brain morphology using voxel-based morphometry to discover the specific regions showing alterations in the respective dimensions of obsessive-compulsive symptoms. The severities of symptom dimensions in thirty-three patients with OCD were assessed using Obsessive-Compulsive Inventory-Revised (OCI-R). Along with numerous MRI studies pointing out brain abnormalities in autistic spectrum disorder (ASD) patients, a previous study reported a positive correlation between ASD traits and regional gray matter volume in the left dorsolateral prefrontal cortex and amygdala in OCD patients. We investigated the correlation between gray and white matter volumes at the whole brain level and each symptom dimension score, treating all remaining dimension scores, age, gender, and ASD traits as confounding covariates. Our results revealed a significant negative correlation between washing symptom dimension score and gray matter volume in the right thalamus and a significant negative correlation between hoarding symptom dimension score and white matter volume in the left angular gyrus. Although our result was preliminary, our findings indicated that there were specific brain regions in gray and white matter that contributed to symptom dimensions in OCD patients.

    Obsessive-compulsive disorder (OCD) is difficult to model in animals due to the involvement of both mental (obsessions) and physical (compulsions) symptoms. Due to limitations of using animals to evaluate obsessions, OCD models are limited to evaluation of the compulsive and repetitive behaviors of animals. Of these, models of adjunctive behaviors offer the most value in regard to predicting efficacy of anti-OCD drugs in the clinic. Adjunctive behaviors are those that are maintained indirectly by the variables that control another behavior, rather than directly by their own typical controlling variables. Schedule-induced polydipsia (SIP) is an adjunctive model in which rats exhibit exaggerated drinking behavior (polydipsia) when presented with food pellets under a fixed-time schedule. The polydipsic response is an excessive manifestation of a normal behavior (drinking), providing face validity to the model. Furthermore, clinically effective drugs for the treatment of OCD decrease SIP. This protocol describes a rat SIP model of OCD and provides preclinical data for drugs that decrease polydipsia and are clinically effective in the treatment of OCD.

    Social phobia is a frequent co-occurring diagnosis with obsessive-compulsive disorder (OCD); however, co-occurring OCD in those with social phobia is less common. Genetic, environmental, and cognitive traits are common risk factors for anxiety disorders broadly. It is plausible that shared variables related to OCD and/or social phobia could provide insight into the co-occurrence of these two disorders. The current study explored differences in fear of negative evaluation (FNE) and perfectionism among four groups: those with (1) elevated social phobia symptoms, (2) elevated OCD symptoms, (3) elevated symptoms of OCD and social phobia, and those who were (4) asymptomatic as a control group. A non-clinical sample of 196 participants completed several online questionnaires about social phobia and OCD symptomology. Results identified three cognitive variables (i.e., FNE, total perfectionism, and concern over mistakes) as differential variables in comorbid symptom presentation of OCD and social phobia. A fourth variable (i.e., doubts about actions) was identified as a potential dual risk factor, and four subsequent variables (i.e., parental criticism, personal standards, parental expectations, and organization) were not implicated in differential symptom presentation. Given the different rates of OCD and social phobia co-occurrence, identification of differentiating variables could aid in better understanding of potential risk factors, which may enhance preventative and therapeutic techniques. Study implications, limitations, and future recommendations are discussed.

    Full text: Obsessive-Compulsive Disorder (OCD) is an anxiety disorder which is increasingly being recognised as a neurobiological disorder. While serotonergic mechanisms have been proposed, the major competing theory in the pathophysiology of OCD involves the neurotransmitter dopamine. The Dopamine D1 receptor is implicated in OCD following the finding of specific spatial working memory abnormalities in a series of neuropsychological studies. Spatial working memory is known to depend on the integrity of D1 receptor function in the Dorso-lateral Prefrontal Cortex (DLPFC) of primates. This study aims to examine the role of dopamine in patients with OCD and in particular to test the hypothesis that there is an upregulation of dopamine D1 receptors in the DLPFC which correlates with spatial working memory deficits in OCD. Three OCD patients and three normal controls underwent Positron Emission Tomography (PET) following intravenous injection of the D1 antagonist PET ligand SCH23390. Reconstructed PET images were co registered with subject Magnetic Resonance Images (MRI) and regions of interest drawn manually. We will present the analysis of the Binding Potentials of SCH23390 in the regions of interest of the first three OCD patients and compare them with three normal control patients. In conclusion Dopamine-Serotonergic interactions are involved in the pathophysiology of OCD. Copyright (2000) The Australian and New Zealand Society of Nuclear Medicine Inc

    Deep brain stimulation (DBS) has been established as a safe, effective therapy for movement disorders (Parkinson's disease, essential tremor, etc.), and its application is expanding to the treatment of other intractable neuropsychiatric disorders including depression and obsessive-compulsive disorder (OCD). Several published studies have supported the efficacy of DBS for severely debilitating OCD. However, questions remain regarding the optimal anatomic target and the lack of a bedside programming paradigm for OCD DBS. Management of OCD DBS can be highly variable and is typically guided by each center's individual expertise. In this paper, we review the various approaches to targeting and programming for OCD DBS. We also review the clinical experience for each proposed target and discuss the relevant neuroanatomy. A PubMed review was performed searching for literature on OCD DBS and included all articles published before March 2012. We included all available studies with a clear description of the anatomic targets, programming details, and the outcomes. Six different DBS approaches were identified. High-frequency stimulation with high voltage was applied in most cases, and predictive factors for favorable outcomes were discussed in the literature. DBS remains an experimental treatment for medication refractory OCD. Target selection and programming paradigms are not yet standardized, though an improved understanding of the relationship between the DBS lead and the surrounding neuroanatomic structures will aid in the selection of targets and the approach to programming. We propose to form a registry to track OCD DBS cases for future clinical study design. © 2013 International Neuromodulation Society.

    Obsessive-compulsive disorder (OCD) is characterized as significant impairment of cognitive-behavioral inhibition, which is causally associated with cognitive processes evoking anxiety, along with increased desire for perfect control over the possible harm, at least in typical OCD patients who have compulsions in response to obsessions. However, OCD has been well conceptualized as a multidimensional and heterogeneous disorder apparently comprising a number of potentially valid subtypes. For example, OCD can be diagnosed by either obsessions or compulsions, and a certain type of OCD patient has only compulsions in response to rules that must be applied rigidly. They often become stuck as a result of rigid rules in every step of their daily working and social life. This type of compulsive behavior is often triggered by specific sensory phenomena such as sight, touch, or personal expression (e. g. need to express himself precisely in written or spoken words). Thus, such OCD patients usually perform their compulsions in order to relieve sensory phenomena such as feelings of incompleteness and urges to reach a specific sensation of feeling "just right", and are less likely to have obsessions or cognitive processes preceding the repetitive behaviors. This type of OCD has also been characterized as "tic-related" and tends to have comorbid conditions such as tic disorders, ADHD or skin picking. Indeed, there are some crucial and significant differences in the psychopathology, phenomenology, and putative biological bases between OCD patients with obsession-related compulsions (cognitive type) and those with compulsions repeated according to rigid rules (motoric type). Because of the substantial heterogeneity of OCD, it seems to be beyond the traditional learning model in which anxiety-driven obsessions entrain neutralizing compulsions and also beyond the essential features of anxiety disorders commonly characterized by psychopathological characteristics such as marked and

    The relationship between obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder (OCPD) has not yet been fully clarified. The aim of the present study was to analyze DSM-IV OCPD prevalence rates in OCD and panic disorder (PD) patients to test for the specificity of the OCPD-OCD link, and to compare them to OCPD prevalence in a control group of subjects without any psychiatric disorder. A total of 109 patients with a principal diagnosis of DSM-IV (SCID-I) OCD and 82 with PD were interviewed using the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) in order to assess the prevalence of OCPD. All patients with a coexisting axis I diagnosis were excluded from the study to eliminate confounding factors when evaluating the association between prevalence rates of OCPD and anxiety disorder diagnoses. An exclusion criteria was also a Hamilton Depression Rating Scale (HAM-D) score >/=16. A sample of comparison subjects (age 18 to 65 years) without any psychiatric disorder was recruited from people registered with two general practitioners (GPs), whether or not they consulted the doctor, in order to evaluate OCPD prevalence rate in the community. A significant difference was found between the prevalence of OCPD in OCD (22.9%) and in PD (17.1%) on one hand, and that in the comparison sample (3.0%) on the other. No differences were found between the two psychiatric groups, even when splitting the samples according to gender. Our study failed to support the hypothesis of a specific relationship between OCPD and OCD; we confirmed the higher prevalence rate of this personality disorder in OCD subjects with regard to the general population, but we also confirmed the higher rate of OCPD in another anxiety disorder which is phenomenologically well characterized and different from OCD, such as PD.

    Full Text Available The care of patients with obsessive-compulsive disorder (OCD has raised quality of life (QOL issues. The purpose of this study was to compare the level of QOL between patients with and without OCD, and to examine the associations between QOL and sociodemographic data, course of illness, psychopathology, perceived social support, and treatment characteristics. The QOL levels measured with the Taiwan version of the Short Form of the World Health Organization Questionnaire on Quality of Life were compared between 57 subjects with OCD and 106 subjects without OCD. The correlates of QOL were examined among subjects with OCD. The analysis revealed that QOL scores for the general, physical, psychological and social relationship domains were lower in the OCD group than in the control group; however, no difference in the environmental domain was found. Multiple factors were associated with poor QOL in subjects with OCD, including comorbid depression, severe obsession symptoms, perceived low social support, severe adverse effects of medication, combined use of mood stabilizers, and low social status. Different domains of QOL are differently affected by OCD. The QOL of subjects with OCD was correlated to multiple factors that were specific to individual subjects and influenced by interactions with treatment and the social environment.

    There are limited data on neurobiological correlates of poor insight in obsessive-compulsive disorder (OCD). This study explored whether specific changes occur in small-world network (SWN) properties in the brain functional network of OCD patients with poor insight. Resting-state electroencephalograms (EEGs) were recorded for 12 medication-free OCD patients with poor insight, 50 medication-free OCD patients with good insight, and 36 healthy controls. Both of the OCD groups exhibited topological alterations in the brain functional network characterized by abnormal small-world parameters at the beta band. However, the alterations at the theta band only existed in the OCD patients with poor insight. A relatively small sample size. Subjects were naïve to medications and those with Axis I comorbidity were excluded, perhaps limiting generalizability. Disrupted functional integrity at the beta bands of the brain functional network may be related to OCD, while disrupted functional integrity at the theta band may be associated with poor insight in OCD patients, thus this study might provide novel insight into our understanding of the pathophysiology of OCD.

    Progress in psychiatry depends on accurate definitions of disorders. As long as there are no known biologic markers available that are highly specific for a particular psychiatric disorder, clinical practice as well as scientific research is forced to appeal to clinical symptoms. Currently, the nosology of obsessive-compulsive disorder is being reconsidered in view of the publication of DSM-V. Since our diagnostic entities are often simplifications of the complicated clinical profile of patients, definitions of psychiatric disorders are imprecise and always indeterminate. This urges researchers and clinicians to constantly think and rethink well-established definitions that in psychiatry are at risk of being fossilised.

    SERT I425V, an uncommon missense single nucleotide polymorphism producing a gain-of-function of the serotonin transporter (SERT), was originally found to segregate with a primarily obsessive-compulsive disorder (OCD) but complexly comorbid phenotype in two unrelated families. As two individuals with SERT I425V and OCD also had Asperger syndrome (AS), an autism spectrum disorder, and as other rare SERT variants have recently shown significant associations with autism, we set out to extend our original OCD study by genotyping additional autism/AS and OCD samples. Case-control association study of SERT I425V in 210 AS/autism probands and 215 controls, plus 335 OCD probands and their family members. SERT I425V was not found in any of the individuals with AS/autism, OCD alone or OCD comorbid with AS and other disorders, or in controls. This results in new estimates of SERT I425V having a 1.5% prevalence in 530 individuals with OCD from five unrelated families genotyped by us and by one other group and a 0.23% frequency in four control populations totaling 1300 individuals, yielding a continuing significant OCD-control difference (Fisher's exact test corrected for family coefficient of identity P=0.004, odds ratio=6.54). As several other uncommon, less well quantitated genetic variations occur with an OCD phenotype, including chromosomal anomalies and some other rare gene variants (SGCE, GCH1 and SLITRK1), a tentative conclusion is that OCD resembles other complex disorders in being etiologically heterogeneous and in having both highly penetrant familial subtypes associated with rare alleles or chromosomal anomalies, as well as having a more common, polygenetic form that may involve polymorphisms in such genes as BDNF, COMT, GRIN2beta, TPH2, HTR2A and SLC1A1.

    Full Text Available Abstract Background Obsessive-compulsive disorder (OCD affects young adults and has great impact on the social, emotional and work spheres. Methods We measured perceived quality of life (QOL in OCD patients, in order to analyse socio-demographic and clinical factors that may be associated with QOL perception. 64 OCD outpatients were assessed with the Mini International Neuropsychiatric Interview for DSM-IV, the Yale-Brown Obsessions and Compulsions scale (Y-BOCS, Hamilton's depression scale and the SF-36 self-administered global QOL perception scale. Results We found a correlation among Hamilton's scale scores and all SF-36 subscales. The severity of the obsessive-compulsive disorder was correlated with all SF-36 subscales and with the highest scores in Hamilton's scale. The obsessions subscale was correlated to all SF-36 subscales, while the compulsions subscale was correlated only to social functioning, emotional role, mental health and vitality. Compulsions were not related to general health perception. There were significant differences between OCD patients and the Spanish general population in all SF-36 subscales except those related to physical health and pain. Gender, age, age of onset of the disorder, years of evolution and marital status of the patients did not significantly affect quality of life perception. Being employed was related to better scores in the subscale of physical role. Patients with medical comorbidity scored lower in the subscales of general health, social functioning and mental health. Patients with comorbid psychiatric disorders had worse scores in the subscales of pain, general health, social functioning and mental health. Conclusion Quality of life perception was different in OCD patients and the general population. Quality of life perception was related to severity of the disorder, physical and psychiatric comorbidity and employment status.

    Guilt plays a significant role in the occurrence and maintenance of obsessive-compulsive disorder (OCD). Two major types of guilt have been identified: one deriving from the transgression of a moral rule (deontological guilt DG), another (altruistic guilt AG), relying on the assumption of having compromised a personal altruistic goal. Clinical evidence suggests that OCD patients are particularly sensitive to DG, but not AG. In this functional magnetic resonance imaging (fMRI) study, we investigated brain response of OCD patients while processing DG and AG stimuli. A previously validated fMRI paradigm was used to selectively evoke DG and AG, and anger and sadness, as control emotions in 13 OCD patients and 19 healthy controls. Patients' behavioral results showed a prominent attitude to experience guilt, compared to controls, while accomplishing task. fMRI results revealed that patients have reduced activation in the anterior cingulate (ACC) and frontal gyrus when experiencing guilt, regardless of its specific type (DG or AG). When separately considering each type of guilt (against each of its control), patients showed decreased activation in the ACC, the insula and the precuneus, for DG. No significant differences were observed between groups when processing AG, anger or sad stimuli. This study provides evidence for an abnormal processing of guilt, and specifically DG, in OCD patients. We suggest that decreased activation may reflect patients' cerebral efficiency, which derives from their frequent exposure to guilty feelings ("neural efficiency hypothesis"). In conclusion, our study confirms a selective abnormal processing of guilt, and specifically DG, in OCD.

    Objective Obsessive-compulsive disorder (OCD) and Tourette syndrome (TS) are heritable, neurodevelopmental disorders with a partially shared genetic etiology. This study represents the first genome-wide investigation of large (>500kb), rare (<1%) copy number variants (CNVs) in OCD and the largest genome-wide CNV analysis in TS to date. Method The primary analyses utilized a cross-disorder design for 2,699 patients (1,613 ascertained for OCD, 1,086 ascertained for TS) and 1,789 controls. Parental data facilitated a de novo analysis in 348 OCD trios. Results Although no global CNV burden was detected in the cross-disorder analysis or in secondary, disease-specific analyses, there was a 3.3-fold increased burden of large deletions previously associated with other neurodevelopmental disorders (p=.09). Half of these neurodevelopmental deletions were located in a single locus, 16p13.11 (5 patient deletions: 0 control deletions, p=0.08 in current study, p=0.025 compared to published controls). Three 16p13.11 deletions were confirmed de novo, providing further support to the etiological significance of this region. The overall OCD de novo rate was 1.4%, which is intermediate between published rates in controls (0.7%) and in autism or schizophrenia (2–4%). Conclusion Several converging lines of evidence implicate 16p13.11 deletions in OCD, with weaker evidence for a role in TS. The trend toward increased overall neurodevelopmental CNV burden in TS and OCD suggests that deletions previously associated with other neurodevelopmental disorders may also contribute to these phenotypes.

    The following review is focusing on results of functional neuroimaging. After some introductory remarks on the phenomenology, epidemiology, and psychotherapy approaches of obsessive-compulsive disorders (OCD) the most important OCD-related brain regions are presented. Obviously, not only the prominent cortico-striato-thalamo-cortical feedback loops are involved, as functional brain imaging studies tell us, but also other regions as the inferior parietal lobe, the anterior and posterior cingulate gyrus, insula, amygdala, cerebellum, and others. Subclassifications using factor-analysis methods support the hypothesis, that most important subtypes ("washing/contamination fear", "obsessions/checking", "symmetry/ordering", "hoarding") involve different, but partially overlapping brain areas. Stimulation paradigms in fMRI-research are commonly based on symptom provocation by visual or tactile stimuli, or on action-monitoring and error-monitoring tasks. Deficits in action-monitoring and planning are discussed to be one of the basic dysfunctions of OCD. Finally, results of psychotherapeutic induced variations of brain activations in OCD are presented.

    The aspects of cultural identity and its impact on obsessive-compulsive disorder (OCD) have been un-derstudied. There are different opinions, ranging from the idea that culture does not affect the symptoms of this condition to the idea that cultures with high religiosity may have more severity of OCD. Also, the concept of OCD has considerably var-ied across history and cultures, from being considered an issue related to lack of control of blasphemous ideas, and a part of anxious issues, to the description of complex neurobiological systems in its causation. The aim of this review was to address OCD as a well-characterized disorder with a proposed neurobiological ba-sis which may or may not have variations depending on cultural diversity. The question that was asked in this review is whether or not there are cultural differences in the manifestations of the OCD symptomatology and which factors of cultural diversity have a major influence on such manifestations along with the differences among some cultures regarding OCD is-sues, where the difference among countries has also been highlighted. A review of the literature was conducted that includes the following words: obsessive-compulsive disorder, cul-ture, cultural identity and religion in a period of 10 years. Cultural variations do not seem to differ from symptomatic clusters of OCD, which may be indicating that a se-ries of adaptive behaviors is evolutionarily evolving to be constantly altered, perhaps by well-determined pathophysiological mechanisms. Some aspects that have been related to some dimensions of OCD symptomatology are religion and religiosity, affecting the content of obsessions and the severity of manifestations. Properly evaluating the education background, access to health services, food, and the genetic structure of populations, using investigational instruments sensitive to these cultural elements, will increase our understanding of the importance of culture on OCD and its treatment.

    Despite having a univocal definition, obsessive-compulsive disorder (OCD) shows a remarkably phenotypic heterogeneity. The published reports show impaired decision-making in OCD patients, using tasks such as the Iowa Gambling Task (IGT). We wanted to verify the hypothesis of an IGT worse performance in a large sample of OCD patients and healthy control (HC) subjects and to examine the relation between neuropsychological performance in IGT and the OCD symptoms heterogeneity. Binary data from the Yale-Brown Obsessive Compulsive Scale collected on a large sample of OCD patients were analyzed using a multidimensional item response theory model to explore the underlying structure of data, thus revealing latent factors. Factor scores were categorized into quartiles. Then, for each factor, we identified patients respectively with the highest versus lowest score. We evaluated whether symptom dimensions affect the probability of a correct answer over time generalized, during IGT performance, fitting a generalized linear mixed model. We found a general deficit in ambiguous decision-making in OCD compared to HC. Moreover, our findings suggested that OCD symptoms heterogeneity affects decision-making learning abilities during IGT. In fact, while 'Symmetry' and 'Washing' patients showed a learning curve during the task, other subgroups did not. Our study confirmed previous findings suggesting that OCD is characterized by a deficit in decision-making under uncertainty. Moreover, our study gave evidence about biological specificity for each symptom dimension in OCD. Data were discussed in the context of the somatic marker hypothesis, which was hypothesized to be reduced in OCD patients. © 2014 The Authors.

    Sexual behavior and formation of sexuality in men with obsessive-compulsive disorder is one of the pressing issues in contemporary medicine. Obsessive-compulsive disorder is characterized by the development of intrusive thoughts, memories, movements and actions, as well as a variety of pathological fears (phobias). Increase in the number of patients with this pathology in modern clinical practice of neurotic disorders, the young age of the patients and as a result violation of interpersonal, communicational and sexual nature is quite apparent. The study involved 35 men aged 23 to 47 years with clinical signs of OCD. We determined the severity of obsessive-compulsive symptoms using the Yale-Brown scale. We established the presence of a mild degree of disorder in 34,3% of cases; in 48,6% of cases disorder of moderate severity was diagnosed; remaining 17.1% were assessed subclinical condition of OCD at the applicable scale. The system of motivational maintenance of sexual behavior in men with obsessive-compulsive disorders is investigated. Motives of sexual behavior of the investigated men with the pathology are determined. The presented research in men with OCD have established multidimensionality and complexity of motivational ensuring of sexual behavior.

    Obsessive-compulsive personality disorder (OCPD) traits and obsessive-compulsive disorder (OCD) are commonly associated with patients with Anorexia Nervosa (AN). The aim of this review was to systematically search the literature to examine whether OCPD and OCD are positively associated with excessive exercise in patients with AN. A systematic electronic search of the literature (using PsycInfo, Medline and Web of Knowledge) was undertaken to identify relevant publications until May 2012. A total of ten studies met criteria for inclusion in the review. The design of the studies varied from cross-sectional to retrospective and quasi-experimental. Seven out of the ten studies reviewed demonstrated a positive relationship between OCPD and/or OCD in AN patients who exercise excessively, whilst three studies found a lack of relationship, or a negative relationship, between these constructs. There is evidence from the literature to suggest that there is a positive relationship between OCPD and excessive exercise in patients with AN. However, the relationship between OCD and excessive exercise is less clear and further research is required to qualify the strength of such relationships. Future research should utilise the most comprehensive and reliable clinical assessment tools, and address prognostic factors, treatment factors and specific interventions for patients with OCPD and/or OCD and excessive exercise.

    Full Text Available Obsessive-compulsive disorder (OCD is a prevalent psychiatric disorder of unknown etiology. However, there is some evidence that the immune system may play an important role in its pathogenesis. In the present study, two polymorphisms (rs1800795 and rs361525 in the promoter region of the cytokine tumor necrosis factor-alpha (TNFA gene were genotyped in 183 OCD patients and in 249 healthy controls. The statistical tests were performed using the PLINK® software. We found that the A allele of the TNFA rs361525 polymorphism was significantly associated with OCD subjects, according to the allelic χ² association test (p=0.007. The presence of genetic markers, such as inflammatory cytokines genes linked to OCD, may represent additional evidence supporting the role of the immune system in its pathogenesis.

    Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder that often runs a chronic unremitting course. Treatment outcomes can be unsatisfactory despite the availability of various somatic and psychological therapies. Psychodynamic psychotherapy in combination with cognitive behavioral therapy (CBT) with exposure and response prevention (ERP) could help patients with treatment-resistant OCD achieve better outcomes. An integrative approach can help patients gain insight, strengthen the therapeutic alliance, improve treatment adherence, and provide symptomatic relief when other treatments seem insufficient or have failed. We describe the treatment process of a person with treatment-resistant OCD who received pharmacotherapy, concurrent CBT/ERP, and a brief course of psychodynamic psychotherapy. Case formulations from cognitive behavioral and psychodynamic perspectives are presented. The authors discuss the advantages of doing a psychodynamic assessment and formulation in treatment refractory cases and the wisdom of integrating psychotherapy interventions for OCD, as well as the unique clinical features of cases that warrant a multimodal treatment approach.

    To determine possible dimensions that underlie obsessive-compulsive personality disorder (OCPD) and to investigate their clinical correlates, familiality, and genetic linkage. Participants were selected from 844 adults assessed with the Structured Instrument for the Diagnosis of DSM-IV Personality Disorders (SIDP) in the OCD Collaborative Genetics Study (OCGS) that targeted families with obsessive-compulsive disorder (OCD) affected sibling pairs. We conducted an exploratory factor analysis, which included the eight SIDP-derived DSM-IV OCPD traits and the indecision trait from the DSM-III, assessed clinical correlates, and estimated sib-sib correlations to evaluate familiality of the factors. Using MERLIN and MINX, we performed genome-wide quantitative trait locus (QTL) linkage analysis to test for allele sharing among individuals. Two factors were identified: Factor 1: order/control (perfectionism, excessive devotion to work, overconscientiousness, reluctance to delegate, and rigidity); and Factor 2: hoarding/indecision (inability to discard and indecisiveness). Factor 1 score was associated with poor insight, whereas Factor 2 score was associated with task incompletion. A significant sib-sib correlation was found for Factor 2 (rICC = .354, P OCPD, order/control and hoarding/indecision. The hoarding/indecision factor is familial and shows modest linkage to a region on chromosome 10. © 2015 Wiley Periodicals, Inc.

    Obsessive Compulsive Disorder (OCD) is a disorder with heterogeneous clinical presentations. To advance our understanding of this heterogeneity we investigated the prevalence and clinical features associated with incompleteness (INC), a putative underlying core feature of OCD. We predicted INC would be prominent in individuals with OCD and associated with greater severity and impairment. We examined the impact of INC in 307 adults with primary OCD. Participants with clinically significant INC (22.8% of the sample) had significantly greater OCD severity, greater rates of comorbidity, poorer ratings of functioning, lower quality of life, and higher rates of unemployment and disability. Participants with clinically significant INC were also more likely to be diagnosed with OCPD and to endorse symmetry/exactness obsessions and ordering/arranging compulsions than those who reported low INC. Our findings provide evidence that INC is associated with greater severity, comorbidity, and impairment, highlighting the need for improved assessment and treatment of INC in OCD.

    Full Text Available Abstract Background Estimates of the annual prevalence for Obsessive Compulsive Disorder (OCD were consistent across the international sites range, 1.9% – 2.5%. The nine population surveys, which used Diagnostic Interview Schedule, estimated a six-month prevalence of OCD ranging from 0.7% to 2.1%. This study performed in order to determine the prevalence of OCD in a population-based study among Iranian adults aged 18 and older and to study the association of them with factors such as sex, marital status, education, type of occupation and residential area. Methods A cross-sectional nationwide epidemiological study of the Iranian population aged 18 and older was designed to estimate the prevalence of psychiatric disorders and their association with the above mentioned factors. 25180 individuals were selected and interviewed through a randomized systematic and cluster sampling method from all Iranian households. Schedule for Affective Disorders and Schizophrenia (SADS and Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV criteria were used in diagnosis of OCD. 250 clinical psychologists interviewed the selected subjects face to face at their homes. Results The prevalence of OCD in Iran is 1.8% (0.7% and 2.8% in males and females; respectively. 50.3% of the survey sample were men, 49.9% women, 29.1% single, 67.45% married, 0.4% separated or divorced, 2.5% widow/widower and 4% undetermined. All of the above-mentioned factors were examined in the univariate and multivariate logistic regression models. Although the data did not fit the models well, but in univariate models, sex, the category "single" of marital status, age, the categories "business" and "housewife" and residential areas showed significant effect adjusting for the factors, but the models didn't fit the data properly. Conclusion The study suggests that the prevalence of OCD is not rare in the community of Iran and is within the range of other countries. Similar to prior

    2010-01-01

    Purpose Obsessive-compulsive disorder (OCD) is a chronic anxiety disorder of unknown aetiology. The purpose of the study is to evaluate the changes of brain function in patients with OCD. Methods: Regional cerebral perfusion was investigated using SPECT in 25 patients with OCD. The mean ages of the patients were 29.04 (1 8-46) years old. The clinical symptom consists of repeating thinking (suspect, worry, nervous) and repeating action (checking, washing, counting, making telephone calls) principally. After administration of 740-925 MBq (20-25 mCi) 99mTc-ECD a single photon emission tomography study was performed and then transaxial, sagittal and coronal slices were obtained. For the semiquantitative analysis of the data Results: 92 per cent of patients (23125) had relative hypoperfusions in some cerebral regions. The patients had a significant decrease of rCBF in the frontal lobes, temporal lobes, basal ganglia, thalamus, and cingulate gyrus. There were no correlation between the change of rCBF and age of age or course of disease. But there were some correlation with clinical symptom. Conclusion: Obsessive-compulsive disorder (OCD) has been linked to a dysfunction of brain orbitofrontal-striatum-pallidum-thalamus networks that were confirmed by PET SPECT functional imaging studies. These study indicated hypoperfusion in frontal lobes, basal ganglion, thalamus in OCD patients, and suggests a reduced serotonergic input into the fronto-subcortical circuits in OCD, thereby diminishing the inhibitory regulation of serotonin on these circuits. According to our results, patients with OCD had profound dysfunction of the frontal and temporal cortices, and basal ganglia. These may reflect a fundamental feature of clinical neuropathophysiology in OCD, and support previous findings about dysfunction of frontal-subcortical circuits in this disorder. (authors)

    Problematic Internet use is a worldwide social issue and it can be found in any age, social, educational, or economic range. In some countries like China and South Korea internet addiction (IA) is considered a public health condition and this governments support research, education and treatment. Internet addiction has been associated with others psychiatric disorders. Panic disorder (PD) and Obsessive Compulsive Disorder (OCD) are anxiety disorders that involve a lot of damages in patient's life. We report a treatment of a patient with Panic Disorder and Obsessive Compulsive Disorder and internet addition involving pharmacotherapy and Cognitive Behavioral Therapy (CBT). The Cognitive Behavioral Therapy was conducted 1 time per week during 10 weeks and results suggest that the treatment was an effective treatment for the anxiety and for the internet addiction.

    2008-01-01

    INTRODUCTION: There is a substantial body of evidence that obsessive-compulsive disorder (OCD) symptoms can be grouped into a series of discrete dimensions, and some evidence that not all OCD symptom dimensions respond equally well to pharmacologic or psychotherapeutic intervention. The response...... of individual Yale-Brown Obsessive-Compulsive Scale items yielded 5 factors (contamination/cleaning, harm/checking, hoarding/symmetry, religious/sexual, and somatic/hypochondriacal). Analyses of covariance including all the subscales demonstrated that escitalopram was more effective than placebo....... There was a significant interaction for the hoarding/symmetry factor, which was associated with a poor treatment response. CONCLUSION: Escitalopram shows good efficacy across the range of OCD symptom dimensions. Nevertheless, hoarding/symmetry was associated with a poorer treatment response. Hoarding/symmetry may...

    This study examined the frequency and sociodemographic and clinical correlates of suicidal ideation in a sample of children and adolescents with obsessive-compulsive disorder (OCD). Fifty-four youth with OCD and their parent(s) were administered the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime, Children’s Yale-Brown Obsessive Compulsive Scale, and Children’s Depression Rating Scale-Revised. Children completed the Suicidal Ideation Questionnaire - Junior, Child Obsessive Compulsive Impact Scale–Child, and Multidimensional Anxiety Scale for Children; parents completed the Child Obsessive Compulsive Impact Scale–Parent, Swanson, Nolan, and Pelham–IV Parent Scale, and Young Mania Rating Scale–Parent Version. Seven youth endorsed clinically significant levels of suicidal ideation on the Suicidal Ideation Questionnaire - Junior. Suicidal ideation was significantly related to clinician-rated depressive symptoms, age, child-rated impairment and anxiety symptoms, and symmetry, sexuality/religiosity and miscellaneous symptom dimensions. There was no significant association between suicidal ideation and obsessive-compulsive symptom severity, comorbidity patterns, or several parent-rated indices (e.g., impairment, impulsivity). These results provide initial information regarding the frequency and correlates of suicidal ideation in treatment-seeking youth with OCD. Clinical implications are discussed, as well as directions for future research. PMID:24682580

    The tic-related subtype of obsessive-compulsive disorder (OCD) has a distinct clinical profile. The course of tic-related OCD has previously been investigated in treatment studies, with inconclusive results. This study aimed to compare clinical profiles between tic-related and tic-free OCD patients and to establish the influence of tics on the 2-year natural course in adult OCD patients. Within the Netherlands OCD Association cohort, 377 patients with a current DSM-IV diagnosis of OCD were divided into a tic-related group (28%) and a tic-free group and compared on clinical variables with t tests or χ² tests. Linear mixed-model analyses were used to compare the 2-year course between the groups, with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) as primary outcome measure. Data were collected from 2005 to 2007 and from 2007 to 2009. Compared to patients with tic-free OCD, those with tic-related OCD reported earlier disease onset (P = .009) and more symmetry/ordering symptoms (P = .002). Overall symptom severity was similar in both groups. Patients with tic-related OCD reported increased traits of attention-deficit hyperactivity (P tic-free OCD group. Clinical improvement at 2-year follow-up (mean = 5.3-point decrease on the Y-BOCS, P tic status (P = .24). This remained unchanged after correcting for baseline differences. Tics do not critically affect the 2-year course of adult OCD, but tic-related OCD shows differences from tic-free OCD, such as early onset and increased autism and ADHD traits, that may indicate a neurodevelopmental subtype. © Copyright 2016 Physicians Postgraduate Press, Inc.

  18. Differential diagnosis between obsessive compulsive disorder and restrictive and repetitive behavioural patterns, activities and interests in autism spectrum disorders.

    Paula-Pérez, Isabel

    2013-01-01

    The obsessive compulsive disorder (OCD) and the restricted and repetitive patterns of behavior, interests and activities inherent to autism spectrum disorders (ASD) share a number of features that can make the differential diagnosis between them extremely difficult and lead to erroneous overdiagnosis of OCD in people with autism. In both cases there may appear to have a fixation on routine, ritualized patterns of verbal and nonverbal behavior, resistance to change, and highly restrictive interests, which becomes a real challenge for differentiating rituals, stereotypes and adherence to routines in ASD from obsessions and compulsions in OCD. This article provides key points to clarify this differential diagnosis through the analysis of emotional valence, content, function and psychological theories that explain the obsessions and compulsions in OCD, and the desire for sameness, stereotyped movements and limited interest in autism. The terms "obsession" and "compulsion" should no longer be used when referring to patterns of behavior, interests or restricted and repetitive activities in autism due to syntonic characteristics, low perception of personal responsibility and low neutralizing efforts. Treatment focuses on changing the environment, the use of socio-communicative compensatory strategies and behavioral modification techniques to improve cognitive and behavioral flexibility. When there is comorbidity between, exposure behavioral and response prevention techniques are then used, followed by others of more cognitive orientation if necessary. Copyright © 2012 SEP y SEPB.

    Full Text Available Whether Obsessive Compulsive Disorder (OCD is associated with an increased attentional bias to emotive stimuli remains controversial. Additionally, it is unclear whether comorbid depression modulates abnormal emotional processing in OCD. This study examined attentional bias to OC-relevant scenes using a visual search task. Controls, non-depressed and depressed OCD patients searched for their personally selected positive images amongst their negative distractors, and vice versa. Whilst the OCD groups were slower than healthy individuals in rating the images, there were no group differences in the magnitude of negative bias to concern-related scenes. A second experiment employing a common set of images replicated the results on an additional sample of OCD patients. Although there was a larger bias to negative OC-related images without pre-exposure overall, no group differences in attentional bias were observed. However, OCD patients subsequently rated the images more slowly and more negatively, again suggesting post-attentional processing abnormalities. The results argue against a robust attentional bias in OCD patients, regardless of their depression status and speak to generalized difficulties disengaging from negative valence stimuli. Rather, post-attentional processing abnormalities may account for differences in emotional processing in OCD.

    Aberrant functional connectivity within the default network is generally assumed to be involved in the pathophysiology of obsessive compulsive disorder (OCD); however, the genetic risk of default network connectivity in OCD remains largely unknown. Here, we systematically investigated default network connectivity in 15 OCD patients, 15 paired unaffected siblings and 28 healthy controls. We sought to examine the profiles of default network connectivity in OCD patients and their siblings, exploring the correlation between abnormal default network connectivity and genetic risk for this population. Compared with healthy controls, OCD patients exhibited reduced strength of default network functional connectivity with the posterior cingulate cortex (PCC), and increased functional connectivity in the right inferior frontal lobe, insula, superior parietal cortex and superior temporal cortex, while their unaffected first-degree siblings only showed reduced local connectivity in the PCC. These findings suggest that the disruptions of default network functional connectivity might be associated with family history of OCD. The decreased default network connectivity in both OCD patients and their unaffected siblings may serve as a potential marker of OCD.

    Full Text Available Background: Studies have shown that in obsessive-compulsive disorder (OCD, there is impairment of neurocognitive functioning during the symptomatic phase. However, studies that explore the "state or trait" dependent nature of these neurocognitive deficits are largely lacking. By comparing the neuropsychological functions of the clinical and subclinical group of OCD patients and healthy controls; we tried to establish whether neuropsychological deficits in OCD were "state" dependent or independent. Materials and Methods: Twenty "mild to moderate" OCD patients, 15 subclinical (remitted OCD patients, and 20 matched healthy controls were compared and assessed on computerized battery of neuropsychological tests including Wisconsin card sorting test, continuous performance test, and spatial working memory test. The observations were statistically analyzed. Results: Executive functions in both the subclinical and clinical groups performed poorly when compared to healthy controls. The patient groups made significantly more wrong responses, more missed responses and took more time to respond. On the test of spatial working memory, the mild to moderate OCD patients showed significant impairment, but not the subclinical patients group. Conclusion: Thus, we conclude that cognitive dysfunctions are core and enduring deficits of OCD, they seem to continue into the subclinical- well state. Certain cognitive deficits, depending on their presence or absence in subclinical cases, may be identified as "state" or "trait" markers of OCD.

    Obsessive-compulsive disorder (OCD) often emerges in childhood or adolescence. The aim of the present study was to evaluate whether adult patients with prepuberal onset differ from subjects with later onset in terms of personality disorder comorbidity. The Structured Clinical Interview for DSM-IV Axis II Disorders was used to assess 148 patients with a principal diagnosis of OCD according to the Structured Clinical Interview for DSM-IV Axis I Disorders. The following two subgroups of subjects were selected according to the age at onset of symptomatology: patients with an early-onset ( or =17 years). Of the 148 patients screened for the present study, 33 (22.3%) had an early onset and 1369 (46.6%) had a later onset. With regard to personality disorders, early-onset patients showed more OC personality disorders (OCPD) than later onset patients. Our finding suggests that OCD in childhood increases the risk for developing OCPD in adulthood, or that early-onset OCD and OCPD share a common pathogenesis.

    Ethological methods used to analyze human obsessive-compulsive disorder (OCD) rituals demonstrated excess of unnecessary repetitions as well as irrelevant, idiosyncratic acts (additions) compared to normal activity. A question that still remains is whether these well-known repetitions and additions are manifested in behaviors unrelated to the OCD rituals. Our objectives were to: (1) assess whether OCD-related repetitions and additions as found in previous studies also affect the patients' activity of filling out questionnaires and (2) evaluate the specificity of these behaviors to OCD as opposed to other anxiety disorders and healthy controls. Several standardized disorder-specific self-report questionnaires were used in order to assess the patient's psychopathologies. The style of filling-out these questionnaires by OCD and non-OCD anxiety outpatients and normal controls was analyzed. Four categories were used: omissions, repetitions, corrections, and additions. The OCD group scored significantly higher on the number of additions as compared with both the anxiety group and the nonclinical group, and significantly higher on the number of corrections and repetitions as compared with the nonclinical group. The hallmarks of OCD, repetitions and additions, are manifested not only in the patient's rituals and thoughts, but in apparently "neutral" tasks that do not a priori involve the intrusive thoughts, urges, and images typical of obsessive-compulsive behavior. Additions seem to be more specific to OCD than repetitions. These two executive faults impede routine functionality of OCD patients in tasks related and unrelated to their rituals. Our study delineates simple, observable behavioral characteristics that distinguish between OCD and non-OCD anxiety patients as well as healthy individuals. These symptomatic behaviors may offer a clue to personality traits or deficits in executive functions that possibly play a part in the pathophysiology of OCD. Our results are an

    The basic concepts underlying compulsive, impulsive and addictive behaviours overlap, which may help explain why laymen use these expressions interchangeably. Although there has been a large research effort to better characterize and disentangle these behaviours, clinicians and scientists are still unable to clearly differentiate them. Accordingly, obsessive-compulsive disorder (OCD), impulse control disorders (ICD) and substance-related disorders (SUD) overlap on different levels, including phenomenology, co-morbidity, neurocircuitry, neurocognition, neurochemistry and family history. In this review we summarize these issues with particular emphasis on the role of the opioid system in the pathophysiology and treatment of OCD, ICD and SUD. We postulate that with progression and chronicity of OCD, the proportion of the OCD-related behaviours (e.g. checking, washing, ordering and hoarding, among others) that are driven by impulsive 'rash' processes increase as involvement of more ventral striatal circuits becomes prominent. In contrast, as SUD and ICD progress, the proportion of the SUD- and ICD-related behaviours that are driven by compulsive 'habitual' processes increase as involvement of more dorsal striatal circuits become prominent. We are not arguing that, with time, ICD becomes OCD or vice versa. Instead, we are proposing that these disorders may acquire qualities of the other with time. In other words, while patients with ICD/SUD may develop 'compulsive impulsions', patients with OCD may exhibit 'impulsive compulsions'. There are many potential implications of our model. Theoretically, OCD patients exhibiting impulsive or addictive features could be managed with drugs that address the quality of the underlying drives and the involvement of neural systems. For example, agents for the reduction or prevention of relapse of addiction (e.g. heavy drinking), which modulate the cortico-mesolimbic dopamine system through the opioid (e.g. buprenorphine and naltrexone

    While initial studies supported the hypothesis that cognitive characteristics that capture cognitive resources act as underlying mechanisms in memory deficits in obsessive-compulsive disorder (OCD), the influence of those characteristics on selective attention has not been studied, yet. In this study, we examined the influence of cognitive self-consciousness (CSC), rumination and worrying on performance in selective attention in OCD and compared the results to a depressive and a healthy control group. We found that 36 OCD and 36 depressive participants were impaired in selective attention in comparison to 36 healthy controls. In all groups, hierarchical regression analyses demonstrated that age, intelligence and years in school significantly predicted performance in selective attention. But only in OCD, the predictive power of the regression model was improved when CSC, rumination and worrying were implemented as predictor variables. In contrast, in none of the three groups the predictive power improved when indicators of severity of obsessive-compulsive (OC) and depressive symptoms and trait anxiety were introduced as predictor variables. Thus, our results support the assumption that mental characteristics that bind cognitive resources play an important role in the understanding of selective attention deficits in OCD and that this mechanism is especially relevant for OCD.

    Few studies have used neuroimaging to characterize treatment-refractory obsessive-compulsive disorder (OCD). This study sought to explore gray matter structure in patients with treatment-refractory OCD and compare it with that of healthy controls. A total of 18 subjects with treatment-refractory OCD and 26 healthy volunteers were analyzed by MRI using a 3.0-T scanner and voxel-based morphometry (VBM). Diffeomorphic anatomical registration using exponentiated Lie algebra (DARTEL) was used to identify structural changes in gray matter associated with treatment-refractory OCD. A partial correlation model was used to analyze whether morphometric changes were associated with Yale-Brown Obsessive-Compulsive Scale scores and illness duration. Gray matter volume did not differ significantly between the two groups. Treatment-refractory OCD patients showed significantly lower gray matter density than healthy subjects in the left posterior cingulate cortex (PCC) and mediodorsal thalamus (MD) and significantly higher gray matter density in the left dorsal striatum (putamen). These changes did not correlate with symptom severity or illness duration. Our findings provide new evidence of deficits in gray matter density in treatment-refractory OCD patients. These patients may show characteristic density abnormalities in the left PCC, MD and dorsal striatum (putamen), which should be verified in longitudinal studies. © 2013. Published by Elsevier Inc.

    Previous studies have indicated that a parental rearing style showing a low level of care on the parental bonding instrument (PBI) is a risk factor for depression, and that there is a relationship between the overprotective rearing style on the PBI and obsessive-compulsive disorder (OCD). However, there is no study on the parental rearing attitudes in depressive patients divided into two groups based on their obsessive traits. In this study, we evaluated the parental rearing attitudes and examined the differences among four groups: depressive patients with severe obsessive traits, depressive patients with mild obsessive traits, OCD patients, and healthy volunteers. We divided the depressive patients into severe and mild groups based on their obsessive traits on the Mausdley Obsessional-Compulsive Inventory (MOCI). We compared PBI scores among four groups of 50 subjects matched for age and sex: depressive patients with severe obsessive traits, depressive patients with mild obsessive traits, OCD patients, and healthy volunteers. The paternal protection scores in the depressive patients with severely obsessive traits and the OCD patients were significantly higher than those in the depressive patients with mildly obsessive traits and healthy volunteers. This study indicated that the depressive patients with severe obsessive traits and the OCD patients have similar paternal controlling and interfering rearing attitudes. We conclude that the paternal controlling and interfering rearing attitudes are linked to the development of OCD and depression with obsessive traits, and are not linked to the development of depression itself.

    Some yoga-based practices have been found to be useful for patients with obsessive compulsive disorder (OCD). The authors could not find a validated yoga therapy module available for OCD. This study attempted to formulate a generic yoga-based intervention module for OCD. A yoga module was designed based on traditional and contemporary yoga literature. The module was sent to 10 yoga experts for content validation. The experts rated the usefulness of the practices on a scale of 1-5 (5 = extremely useful). The final version of the module was pilot-tested on patients with OCD (n = 17) for both feasibility and effect on symptoms. Eighty-eight per cent (22 out of 25) of the items in the initial module were retained, with modifications in the module as suggested by the experts along with patients' inputs and authors' experience. The module was found to be feasible and showed an improvement in symptoms of OCD on total Yale-Brown Obsessive-Compulsive Scale (YBOCS) score (p = 0.001). A generic yoga therapy module for OCD was validated by experts in the field and found feasible to practice in patients. A decrease in the symptom scores was also found following yoga practice of 2 weeks. Further clinical validation is warranted to confirm efficacy.

    Altered reward processing and cognitive deficits are often observed in patients with obsessive-compulsive disorder (OCD); however, whether the imbalance in activity between reward circuits and the cognitive control (CC) system is associated with compulsive behavior remains unknown. Sixty-eight OCD patients and 33 cognitively normal (CN) healthy subjects participated in this resting-state functional magnetic resonance imaging study. Alterations in the functional connectivity between reward circuits and the CC system were quantitatively assessed and compared between the groups. A Granger causality analysis was used to determine the causal informational influence between and within reward circuits and the CC system across all subjects. OCD patients showed a dichotomous pattern of enhanced functional coupling in their reward circuits and a weakened functional coupling in their CC system when compared to CN subjects. Neural correlates of compulsive behavior were primarily located in the reward circuits and CC system in OCD patients. Importantly, the CC system exerted a reduced interregional causal influence over the reward system in OCD patients relative to its effect in CN subjects. The limitations of this study are that it was a cross-sectional study and the potential effects of environmental and genetic factors were not explored. OCD patients showed an imbalance in the functional link between reward circuits and the CC system at rest. This bias toward a loss of control may define a pathological state in which subjects are more vulnerable to engaging in compulsive behaviors.

  12. Effects of Anterior Capsulotomy on Decision Making in Patients with Refractory Obsessive–Compulsive Disorder

    Full Text Available Despite various lines of evidence implicating impaired decision-making ability in individuals with obsessive–compulsive disorder (OCD, neuropsychological investigation has generated inconsistent findings. Although the cortico-striato-thalamo-cortical (CSTC circuitry has been suggested, the involvement of the cortex has not yet been fully demonstrated. Moreover, it is unknown whether surgical intervention on the CSTC circuitry results in a predicted improvement of decision-making ability of OCD. Here we present a study of decision making based on the Iowa Gambling Task (IGT to investigate decision making in a large sample of individuals with treatment-resistant OCD with and without anterior capsulotomy (AC. Task performance was evaluated in healthy subjects, individuals with OCD that had not undergone surgery, and postsurgical OCD patients with AC. The latter group was further divided into a short-term postsurgical group and a long-term postsurgical group. We found that the OCD patients without surgery performed significantly worse than the healthy controls on the IGT. There were no significant differences in decision-making between the presurgical OCD patients and those at the short-term postsurgical follow-up. Decision-making ability of the long-term postsurgical OCD patients was improved to the level comparable to that of healthy controls. All clinical symptoms (OCD, depression, and anxiety assessed by psychiatric rating scales were significantly alleviated post-surgically, but exhibited no correlation with their IGT task performance. Our findings provide strong evidence that OCD is linked to impairments in decision-making ability; that impaired CSTC circuitry function is directly involved in the manifestation of OCD; and that AC related improvements in cognitive functions are caused by long-term plasticity in the brain circuitry.

    Full Text Available Objective: To explore the relationship between regional cerebral blood flow (CBF and cognitive function in obsessive-compulsive disorder (OCD. Method: Single-photon emission computed tomography (SPECT was performed for 139 OCD patients and 139 controls, and the radioactivity rate (RAR was calculated. Cognitive function was assessed by the Wisconsin Card Sorting Test (WCST. Results: The RARs of the prefrontal, anterior temporal, and right occipital lobes were higher in patients than controls. For the WCST, correct and classification numbers were significantly lower, and errors and persistent errors were significantly higher in OCD patients. Right prefrontal lobe RAR was negatively correlated with correct numbers, right anterior temporal lobe RAR was positively correlated with errors, and the RARs of the right prefrontal lobe and left thalamus were positively correlated with persistent errors. Conclusion: OCD patients showed higher CBF in the prefrontal and anterior temporal lobes, suggesting that these areas may be related with cognitive impairment.

    Two methods for predicting remissions in obsessive-compulsive disorder (OCD) treatment are evaluated. Y-BOCS measurements of 88 patients with a primary OCD (DSM-III-R) diagnosis were performed over a 16-week treatment period, and during three follow-ups. Remission at any measurement was defined as a Y-BOCS score lower than thirteen combined with a reduction of seven points when compared with baseline. Logistic regression models were compared with a Cox regression for recurrent events model. Logistic regression yielded different models at different evaluation times. The recurrent events model remained stable when fewer measurements were used. Higher baseline levels of neuroticism and more severe OCD symptoms were associated with a lower chance of remission, early age of onset and more depressive symptoms with a higher chance. Choice of outcome time affects logistic regression prediction models. Recurrent events analysis uses all information on remissions and relapses. Short- and long-term predictors for OCD remission show overlap.

    Full Text Available Obsessive-compulsive disorder (OCD is among the most debilitating psychiatric disorders. Comorbid autism spectrum disorder (ASD or autistic traits may impair treatment response in OCD. To identify possible neurostructural deficits underlying autistic traits, we performed white matter tractography on diffusion tensor images (DTI and assessed autistic trait severity using the Autism-Spectrum Quotient (AQ in 33 OCD patients. Correlations between AQ and the DTI parameters, fractional anisotropy (FA, mean diffusivity (MD, axial diffusivity (AD, and radial diffusivity (RD were examined in major white matter tracts that were suggested to be altered in previous OCD studies. We found a negative correlation between AQ and FA and positive correlations between AQ and MD, AD and RD in the left uncinate fasciculus using age, Beck Depression Inventory, Yale-Brown Obsessive-Compulsive Scale, intelligence quotient and medication as covariates. However, we could not detect the significant results between AQ and all DTI parameters when adding gender as a covariate. In addition, in the ASD comorbid group, FA in the left uncinate fasciculus was significantly lower than in the non-ASD comorbid group and MD and RD were significantly higher than in the non-ASD group. These results did not survive correction for multiple comparisons. In ASD, the socio-emotional dysfunction is suggested to be related to the alteration of white matter microstructure in uncinate fasciculus. Our results suggest that variations in white matter features of the left uncinate fasciculus might be partly explained by autistic traits encountered in OCD patients.

    Factor analyses indicate that hoarding symptoms constitute a distinctive dimension of obsessive-compulsive disorder (OCD), usually associated with higher severity and limited insight. The aim was to compare demographic and clinical features of OCD patients with and without hoarding symptoms. A cross sectional study was conducted with 1001 DSM-IV OCD patients from the Brazilian Research Consortium of Obsessive-Compulsive Spectrum Disorders (CTOC), using several instruments. The presence and severity of hoarding symptoms were determined using the Dimensional Yale-Brown Obsessive-Compulsive Scale. Statistical univariate analyses comparing factors possibly associated with hoarding symptoms were conducted, followed by logistic regression to adjust the results for possible confounders. Approximately half of the sample (52.7%, n = 528) presented hoarding symptoms, but only four patients presented solely the hoarding dimension. Hoarding was the least severe dimension in the total sample (mean score: 3.89). The most common lifetime hoarding symptom was the obsessive thought of needing to collect and keep things for the future (44.0%, n = 440). After logistic regression, the following variables remained independently associated with hoarding symptoms: being older, living alone, earlier age of symptoms onset, insidious onset of obsessions, higher anxiety scores, poorer insight and higher frequency of the symmetry-ordering symptom dimension. Concerning comorbidities, major depressive, posttraumatic stress and attention deficit/hyperactivity disorders, compulsive buying and tic disorders remained associated with the hoarding dimension. OCD hoarding patients are more likely to present certain clinical features, but further studies are needed to determine whether OCD patients with hoarding symptoms constitute an etiologically discrete subgroup.

    Obsessive-compulsive disorder (OCD) is a serious condition that remains understudied in ethnoracial minority populations. The presence of OCD and the individual, familial, and cultural factors that influence this condition can interfere with healthy development and cause lifelong disability. To date, there has not been a single published research article focused on OCD in African American youth. Ethnic and racial minorities with OCD are underrepresented or altogether absent from treatment centers and research studies, although evidence suggests that OCD may be particularly persistent in these populations. This article reviews risk factors, protective factors, and barriers to treatment in African American children and adolescents with OCD. This review conceptualizes cultural differences in symptomology, low income, reduced access to care, racism, and mental health stigma, as risk factors. Also discussed are the roles of family factors in the development and maintenance of the disorder, including family accommodations, conflictual family communication, and parenting styles. Potential protective factors are also examined, including a positive ethnic identity, social support, present-centered time orientation, and religious communities. Implications of findings are discussed. There is an urgent need for research to understand the needs of African American children and adolescents with OCD.

    A significant number of obsessive-compulsive disorder (OCD) patients continue to experience symptoms that interfere with their functioning following cognitive behavioural therapy (CBT). Providing an additional augmentation treatment following CBT could help reduce these residual symptoms. Mindfulness interventions that facilitate less reactivity to thoughts and feelings may be helpful for patients suffering from residual OCD symptoms. The purpose of the current randomized waitlist control trial was to evaluate the feasibility and impact of providing an 8-week mindfulness-based cognitive therapy (MBCT) intervention following completion of a CBT intervention to OCD patients who continued to suffer from significant symptoms. Results indicated that compared to the waitlist control group, MBCT participants reported decreases in OCD symptoms (d = 1.38), depression symptoms (d = 1.25), anxiety symptoms (d = 1.02), and obsessive beliefs (d = 1.20) along with increases in self-compassion (d = 0.77) and mindfulness skills (d = 0.77). Additionally, participants reported high levels of satisfaction with the MBCT intervention. The results suggest that the use of MBCT for OCD as an augmentation therapy is acceptable to patients who continue to suffer from OCD symptoms after completing CBT and provides some additional relief from residual symptoms. Mindfulness interventions teach skills that facilitate disengaging from cognitive routines and accepting internal experience, and these skills may be valuable in treating obsessive-compulsive disorder (OCD), as individuals describe getting "stuck" in repetitive thoughts and consequent rituals. The results of this study suggest that teaching mindfulness skills using an 8-week mindfulness-based cognitive therapy (MBCT) intervention provides an added benefit (decreases in OCD, depression, and anxiety symptoms) for patients with OCD who have completed a cognitive behavioural therapy intervention and continued to suffer from

    Full Text Available In obsessive-compulsive disorder (OCD, individuals feel compelled to repeatedly perform security-related behaviors, even though these behaviours seem excessive and unwarranted to them. The present research investigated two alternative ways of explaining such behavior: (1 a dysfunction of activation--a starting problem--in which the level of excitation in response to stimuli suggesting potential danger is abnormally strong; versus (2 a dysfunction of termination--a stopping problem--in which the satiety-like process for shutting down security-related thoughts and actions is abnormally weak.In two experiments, 70 patients with OCD (57 with washing compulsions, 13 with checking compulsions and 72 controls were exposed to contamination cues--immersing a hand in wet diapers--and later allowed to wash their hands, first limited to 30 s and then for as long as desired. The intensity of activation of security motivation was measured objectively by change in respiratory sinus arrythmia. Subjective ratings (e.g., contamination and behavioral measures (e.g., duration of hand washing were also collected.Compared to controls, OCD patients with washing compulsions did not differ significantly in their levels of initial activation to the threat of contamination; however, they were significantly less able to reduce this activation by engaging in the corrective behavior of hand-washing. Further, the deactivating effect of hand-washing in OCD patients with checking compulsions was similar to that for controls, indicating that the dysfunction of termination in OCD is specific to the patient's symptom profile.These results are the first to show that OCD is characterized by a reduced ability of security-related behavior to terminate motivation evoked by potential danger, rather than a heightened initial sensitivity to potential threat. They lend support to the security-motivation theory of OCD (Szechtman & Woody, 2004 and have important implications both for

    Full Text Available Obsessive-compulsive personality disorder (OCPD is an early-onset disorder characterized by perfectionism, need for control, and cognitive rigidity. Its nosological status is currently under review. Historically, OCPD has been conceptualized as bearing a close relationship with obsessive-compulsive disorder (OCD. In this article, we discuss the diagnosis of OCPD in anticipation of its review for the ICD-11, from the perspective of clinical utility, global applicability, and research planning. Considering the recent establishment of an obsessive-compulsive and related disorders (OCRD category in DSM-5, we focus on the relationship between OCPD and the disorders that are currently thought to bear a close relationship with OCD, including DSM-5 OCRD, and other compulsive disorders such as eating disorder and autistic spectrum disorder (that were not included in the DSM-5 OCRD category, as well as with the personality disorders, focusing on nosological determinants such as phenomenology, course of illness, heritability, environmental risk factors, comorbidity, neurocognitive endophenotypes, and treatment response. Based on this analysis, we attempt to draw conclusions as to its optimal placement in diagnostic systems and draw attention to key research questions that could be explored in field trials.

    Obsessive-compulsive personality disorder (OCPD) is an early-onset disorder characterized by perfectionism, need for control, and cognitive rigidity. Its nosological status is currently under review. Historically, OCPD has been conceptualized as bearing a close relationship with obsessive-compulsive disorder (OCD). In this article, we discuss the diagnosis of OCPD in anticipation of its review for the ICD-11, from the perspective of clinical utility, global applicability, and research planning. Considering the recent establishment of an obsessive-compulsive and related disorders (OCRD) category in DSM-5, we focus on the relationship between OCPD and the disorders that are currently thought to bear a close relationship with OCD, including DSM-5 OCRD, and other compulsive disorders such as eating disorder and autistic spectrum disorder (that were not included in the DSM-5 OCRD category), as well as with the personality disorders, focusing on nosological determinants such as phenomenology, course of illness, heritability, environmental risk factors, comorbidity, neurocognitive endophenotypes, and treatment response.

    Full Text Available Objective: Obsessive-compulsive disorder (OCD is characterized by anxiety-provoking, obsessive thoughts (i.e., obsessions which patients react to with compulsive behaviors (i.e., compulsions. Due to the transient feeling of relief following the reduction of obsession-induced anxiety, compulsions are often described as relieving or even rewarding. Several studies investigated functional activation during reward processing in OCD, but findings are heterogeneous up to now and little is known about potential alterations in functional connectivity.Method: Against this background we studied OCD patients (n = 44 and healthy controls (n = 37 during the receipt of monetary reward by assessing both activation and functional connectivity.Results: Patients showed a decreased activation in several frontal regions and the posterior cingulate (PCC, BA31 together with a stronger connectivity between the PCC and the vmPFC (BA10.Conclusion: Present findings demonstrate an increased connectivity in patients within major nodes of the default mode network (DMN—a network known to be involved in the evaluation of internal mental states. These results may indicate an increased activity of internal, self-related processing at the expense of a normal responsiveness toward external rewards and incentives. This, in turn, may explain the constant urge for additional reinforcement and patients' inability to inhibit their compulsive behaviors.

    Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder causing intrusive thoughts or repetitive behaviors. Serotonin reuptake inhibitors are used for OCD treatment, but 40%-60% of patients do not respond to them adequately. In this study, the associations of serotonin receptor 2a polymorphisms rs6311 and rs6313 with OCD, its familial form and fluvoxamine treatment response in Iranian population were investigated. Association analyses were conducted in 293 OCD cases fulfilling the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR and 245 controls. Pharmacotherapy was defined as 12 weeks of treatment with fluvoxamine (150-300 mg). Treatment response was considered as >25% reduction in Yale-Brown Obsessive Compulsive Scale score. Genotyping was performed by means of PCR-RFLP. The results showed no association of rs6311 or rs6313 with OCD, but their haplotypes had different distribution patterns in cases and controls. Moreover, rs6313 was associated with the familial form of OCD in females significantly ( P =0.005) under the recessive genetic model. Moreover, rs6311-rs6313 haplotypes were associated with fluvoxamine treatment response in OCD patients with more AC and less AT in responders. HTR2A haplotypes are associated with OCD and its treatment response with a fluvoxamine in Iranian patients. Furthermore, the observed association of rs6313 with the familial form of OCD in females suggests different genetic background of OCD familial and non-familial forms, which needs further investigation.

The increased risk of manic/hypomanic switch hinders the use of antidepressants for managing coexisting OCD symptoms in BD patients. We herein present a case of a patient with BD–OCD comorbidity, who was successfully treated with mood stabilizers and aripiprazole augmentation. The young female patient reported recurrent depressive episodes and aggravating compulsive behaviors before hospitalization. Of note, the patient repetitively attempted suicide and reported dangerous driving because of intolerable mental sufferings. The preexisting depressive episode and OCD symptoms prompted the use of paroxetine, which consequently triggered the manic switching. Her diagnosis was revised into bipolar I disorder. Minimal response with mood stabilizers prompted the addition of aripiprazole (a daily dose of 10 mg, which helped to achieve significant remission in emotional and obsessive–compulsive symptoms. This case highlights the appealing efficacy of a small dose of aripiprazole augmentation for treating BD–OCD comorbidity. Well-designed clinical trials are warranted to verify the current findings.

    The objectives of this study were to identify unique clinical characteristics of children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) compared with a control group of children with non-PANDAS obsessive-compulsive disorder (OCD) with respect to ancillary symptoms, types of obsessions and compulsions, symptom severity, and co-morbid DSM-IV diagnoses. Classification of PANDAS was based on review of pediatric and psychiatric records using the criteria developed by Swedo and colleagues. Children aged 6-14 with PANDAS (n = 21) and non-PANDAS OCD (n = 18) were assessed by blind independent evaluators using the PANDAS Questionnaire, Children's Yale-Brown Obsessive Compulsive Scale, Yale Global Tic Severity Scale, and Anxiety Disorders Interview Schedule for DSM-IV. PANDAS children were significantly more likely to present with separation anxiety, urinary urgency, hyperactivity, impulsivity, deterioration in handwriting, and decline in school performance during their initial episode of neuropsychiatric illness compared with children with OCD. Total tics and vocal tics were more severe in PANDAS children. Separation anxiety disorder and social phobia were more prevalent in non-PANDAS OCD children. Children with non-PANDAS OCD were significantly more likely to include others in their rituals. There were no significant differences between groups on demographics or severity of OCD. Distinguishing clinical characteristics in PANDAS, which included urinary urgency, hyperactivity, impulsivity, and deterioration in handwriting, are linked to basal ganglia functions. These clinical characteristics will aid in the differentiation of PANDAS children for research and clinical purposes and ultimately advance our understanding and treatment of this disorder.

    To our knowledge, no psychotherapy treatment studies for compulsive buying have been published. The authors conducted a pilot trial comparing the efficacy of a group cognitive behavioral intervention designed for the treatment of compulsive buying to a waiting list control. Twenty-eight subjects were assigned to receive active treatment and 11 to the waiting list control group. The results at the end of treatment showed significant advantages for cognitive behavioral therapy (CBT) over the waiting list in reductions in the number of compulsive buying episodes and time spent buying, as well as scores on the Yale-Brown Obsessive Compulsive Scale--Shopping Version and the Compulsive Buying Scale. Improvement was well-maintained at 6-month follow-up. The pilot data suggests that a cognitive behavioral intervention can be quite effective in the treatment of compulsive buying disorder. This model requires further testing.

  9. Obsessive-compulsive Disorder patients have a reduced sense of control on the illusion of control task

    Full Text Available There is disagreement regarding then role of perceived control in obsessive-compulsive disorder (OCD. The present study used a traditional illusion of control paradigm (Alloy & Abramson, 1979 to empirically test control estimation in OCD. Twenty-six OCD patients and 26 matched comparison subjects completed an illusion of control task wherein their goal was to attempt to exert control over a light bulb. The density of reinforcement (high, low and the valence of trials (gain, loss were experimentally manipulated within subjects. Unbeknownst to participants, the illumination of the light bulb was predetermined and irrespective of their behavior. OCD patients exhibited lower estimates of control compared with healthy comparison subjects. There were no interactions between group and outcome density or group and valence. We found that OCD patients endorse lower estimates of control than comparison subjects. This finding highlights a potential role for contingency learning in the disorder.

    Full Text Available The direct estimation of heritability from genome-wide common variant data as implemented in the program Genome-wide Complex Trait Analysis (GCTA has provided a means to quantify heritability attributable to all interrogated variants. We have quantified the variance in liability to disease explained by all SNPs for two phenotypically-related neurobehavioral disorders, obsessive-compulsive disorder (OCD and Tourette Syndrome (TS, using GCTA. Our analysis yielded a heritability point estimate of 0.58 (se = 0.09, p = 5.64e-12 for TS, and 0.37 (se = 0.07, p = 1.5e-07 for OCD. In addition, we conducted multiple genomic partitioning analyses to identify genomic elements that concentrate this heritability. We examined genomic architectures of TS and OCD by chromosome, MAF bin, and functional annotations. In addition, we assessed heritability for early onset and adult onset OCD. Among other notable results, we found that SNPs with a minor allele frequency of less than 5% accounted for 21% of the TS heritability and 0% of the OCD heritability. Additionally, we identified a significant contribution to TS and OCD heritability by variants significantly associated with gene expression in two regions of the brain (parietal cortex and cerebellum for which we had available expression quantitative trait loci (eQTLs. Finally we analyzed the genetic correlation between TS and OCD, revealing a genetic correlation of 0.41 (se = 0.15, p = 0.002. These results are very close to previous heritability estimates for TS and OCD based on twin and family studies, suggesting that very little, if any, heritability is truly missing (i.e., unassayed from TS and OCD GWAS studies of common variation. The results also indicate that there is some genetic overlap between these two phenotypically-related neuropsychiatric disorders, but suggest that the two disorders have distinct genetic architectures.

    Background Exaggerated amygdala activation to threatening faces has been detected in adults and children with anxiety disorders, compared to healthy comparison subjects. However, the profile of amygdala activation in response to facial expressions in obsessive-compulsive disorder (OCD) may be a distinguishing feature; a prior study found that compared with healthy adults, adults with OCD exhibited less amygdala activation to emotional and neutral faces, relative to fixation (Cannistraro et al., 2004). Methods In the current event-related functional magnetic resonance imaging (fMRI) study, a pediatric OCD sample (N=12) and a healthy comparison sample (HC, N=17) performed a gender discrimination task while viewing emotional faces (happy, fear, disgust) and neutral faces. Results Compared to the HC group, the OCD group showed less amygdala/hippocampus activation in all emotion and neutral conditions relative to fixation. Conclusions Like previous reports in adult OCD, pediatric OCD may have a distinct neural profile from other anxiety disorders, with respect to amygdala activation in response to emotional stimuli that are not disorder-specific.

    At least 10% of patients with Obsessive-compulsive Disorder (OCD) are refractory to psychopharmacological treatment. The emergence of new technologies for the modulation of altered neuronal activity in Neurosurgery, deep brain stimulation (DBS), has enabled its use in severe and refractory OCD cases. The objective of this article is to review the current scientific evidence on the effectiveness and applicability of this technique to refractory OCD. We systematically reviewed the literature to identify the main characteristics of deep brain stimulation, its use and applicability as treatment for obsessive-compulsive disorder. Therefore, we reviewed PubMed/Medline, Embase and PsycINFO databases, combining the key-words 'Deep brain stimulation', 'DBS' and 'Obsessive-compulsive disorder' 'OCS'. The articles were selected by two of the authors independently, based on the abstracts, and if they described any of the main characteristics of the therapy referring to OCD: applicability; mechanism of action; brain therapeutic targets; efficacy; side-effects; co-therapies. All the information was subsequently extracted and analysed. The critical analysis of the evidence shows that the use of DBS in treatment-resistant OCD is providing satisfactory results regarding efficacy, with assumable side-effects. However, there is insufficient evidence to support the use of any single brain target over another. Patient selection has to be done following analyses of risks/benefits, being advisable to individualize the decision of continuing with concomitant psychopharmacological and psychological treatments. The use of DBS is still considered to be in the field of research, although it is increasingly used in refractory-OCD, producing in the majority of studies significant improvements in symptomatology, and in functionality and quality of life. It is essential to implement random and controlled studies regarding its long-term efficacy, cost-risk analyses and cost/benefit. Copyright

    Obsessive-compulsive disorder (OCD) is a severely distressing disorder represented by obsessions and compulsions. A significant proportion of OCD patients fail to improve with conventional treatment methods. Repetitive transcranial magnetic stimulation (rTMS) has been proposed as an alternative for OCD treatment. Functional neuroimaging studies indicate that OCD is associated with increased activity in the supplementary motor area (SMA), a region that plays an important role in the pathophysiology of this disorder. In this study, we assessed the efficacy of augmentation with 1Hz rTMS over the SMA in treatment-resistant OCD patients. The participants received 1Hz rTMS over the SMA in 20 daily sessions for 4weeks. We observed significant reduction in Yale-Brown Obsessive Compulsive Scale (Y-BOCS) score at the 4th week of the treatment. Reduction in compulsion contributed to the reduction of global Y-BOCS whereas there was no significant reduction in obsession. Clinical global impression-global improvement also showed significant change at the 2nd and 4th week of the treatment. No additional significant changes or significant adverse effects were seen. These findings suggest that 1Hz rTMS over the SMA can be an efficient and safe add-on therapeutic method in treatment-resistant patients with OCD. Further controlled studies in larger samples are required to confirm the effect of 1Hz rTMS over the SMA in OCD. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Previous research has shown that among the various subtypes of obsessive-compulsive disorder (OCD), adults (e.g. Frost, Krause & Steketee, 1996) and older children and adolescents (Bloch et al., 2009; Storch et al., 2007) with problematic hoarding have distinct features and a poor treatment prognosis. However, there is limited information on the phenomenology and prevalence of hoarding behaviors in young children. The present study characterizes children ages 10 and under who present with OCD and hoarding behaviors. Sixty-eight children received a structured interview-determined diagnosis of OCD. Clinician administered, parent-report, and child-report measures on demographic, symptomatic, and diagnostic variables were completed. Clinician ratings of hoarding symptoms and parent and child endorsement of the hoarding item on the CY-BOCS checklist (Scahill, Riddle, McSwiggin-Hardin, & Ort, 1997) determined inclusion in the hoarding group ( n =33). Compared to children without hoarding symptoms ( n =35), the presence of hoarding symptoms was associated with an earlier age of primary diagnosis onset and a higher proportion of ADHD and provisional anxiety diagnoses. These results are partially consistent with the adult literature and with findings in older children (Storch et al., 2007). Additional data on clinical presentation and phenomenology of hoarding are needed to form a developmentally appropriate definition of the behavior.

    The etiology of obsessive-compulsive disorder (OCD) is assumed to involve interactions between genetically determined vulnerability factors and significant environmental features. Here, we aim to investigate how the personality trait harm avoidance and the experience of childhood adversities contribute to OCD. A total of 169 patients with OCD, 157 healthy comparison subjects, and 57 unaffected first-degree relatives of patients with OCD participated in the study. Harm avoidance was assessed using the Temperament and Character Inventory, and the severity of childhood adversities was measured with the Childhood Trauma Questionnaire. Both patients with OCD and relatives showed elevated levels of harm avoidance compared to controls. Furthermore, patients exhibited significantly higher scores than relatives. This linear pattern was observed throughout all subscales of harm avoidance, and remained stable after controlling for the severity of depressive and obsessive-compulsive symptoms. With regard to childhood adversities, patients with OCD reported higher levels than relatives and controls. Our results provide further evidence for a diathesis-stress model of OCD. While patients and unaffected relatives share elevated levels of harm avoidance, supporting the role of harm avoidance as an endophenotype of OCD, a heightened severity of childhood adversity was only observed in patients. The assumed biological underpinnings of these findings are discussed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Previous neuropsychological studies produced inconsistent results with tasks tapping short-term verbal and visual-spatial memory and executive functions in obsessive compulsive disorder (OCD). The aim of this study was to investigate the presence of deficits in these cognitive domains. A further goal was to describe the distribution of patients in different impairment ranges for all functions, and clarify the relationship between symptom severity and cognitive impairments. Thirty patients with OCD (DSM-IV) and 30 healthy volunteers were compared using well-known neuropsychological tasks. We assessed short-term verbal memory with the Digit Span Forward and Digit Span Backward Tasks, short-term visual-spatial memory with the Corsi Block Tapping Task, while we measured the level of executive functions with the StroopTask and the Wisconsin Card Sorting Test (WCST). Compared with a matched healthy control group, the performance of OCD patients was in the impaired range only in the two executive tasks. We find a significant positive correlations between the Y-BOCS (Yale-Brown Obsessive Compulsive Scale) total scores and the number of perseverative responses (r(28) = 0.409, p short-term memory is intact in OCD. This is in line with neuropsychological model of OCD that the deficit of cognitive and behavioral inhibition are responsible for the main cognitive findings of this disorder, most prevalently the deficit in set shifting and prepotent response inhibition.

    State-of-the-art treatment of anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) often proves ineffective. Both disorders have common features, and anterior capsulotomy is a last-resort treatment for OCD. We document the effect of bilateral anterior capsulotomy in a patient with comorbid AN and OCD. A 38-year-old woman with life-threatening, chronic, treatment-refractory AN and OCD underwent anterior capsulotomy. Psychiatric and neuropsychological evaluations at baseline and at follow-up document the severity and progress of the case. Bilateral anterior capsulotomy resulted in normalization of eating pattern and weight and a significant decrease of food-related and overall obsessive-compulsive symptoms. Psychiatric evaluations and exposure to food cues confirmed the clinical improvement that was evident immediately after surgery and sustained at 3-month follow-up. This case report suggests that bilateral anterior capsulotomy can be a therapeutic option for patients with comorbid AN and OCD. However, a well-controlled study is warranted.

    Social phobia and obsessive-compulsive disorder (OCD) share several similarities: both are categorized as anxiety disorders, avoidant personality disorder and depression are common in both, they have a similar age of onset and course, and both disorders respond to treatments with serotonin reuptake inhibitors and cognitive behavioural therapy. However, OCD and social phobia differ in respect to their relation to autism spectrum disorders (ASD; i.e. Asperger's syndrome, autism, pervasive disorder not otherwise specified). Findings that suggest a link between OCD and ASD have no parallel in social phobia. Moreover, obsessive-compulsive, paranoid and schizotypal personality disorders are prevalent in OCD and in ASD, but not in social phobia. Individuals with ASD are known to be frequent targets of bullying. We hypothesised that individuals with autistic traits would have been frequent targets for bullies during their childhood, as opposed to people without such traits. Adult patients with social phobia (n = 63) or OCD (n = 65) were assessed regarding autistic traits, and interviewed about being bullied at school. A reference group (n = 551) responded to questions about being bullied. There was a significant difference in the prevalence of being bullied between OCD (50%), social phobia patients (20%) and the reference group (27%). Autistic traits were more common in OCD than in social phobia. A history of being bullied was related to autistic traits among patients. Falling victim to bullying is not a random event. Autistic traits, i.e. low social skills, may be a predictor of being bullied in school. The high rate of bullying victims in persons who later develop OCD is suggested to be related to the overlap between OCD and ASD. Copyright 2009 S. Karger AG, Basel.

    Prior research has identified OCD subtypes or "clusters" of symptoms that differentially relate to clinical features of the disorder. Given the high comorbidity between OCD and anxiety, OCD symptom clusters may more broadly associate with fear and/or distress internalizing constructs. This study examines fear and distress dimensions, including physical concerns (fear), separation anxiety (fear), perfectionism (distress), and anxious coping (distress), as predictors of previously empirically-derived OCD symptom clusters in a sample of 215 youth diagnosed with primary OCD (ages 7-17, mean age = 12.25). Self-reported separation fears predicted membership in Cluster 1 (aggressive, sexual, religious, somatic obsessions, and checking compulsions) while somatic/autonomic fears predicted membership in Cluster 2 (symmetry obsessions and ordering, counting, repeating compulsions). Results highlight the diversity of pediatric OCD symptoms and their differential association with fear, suggesting the need to carefully assess both OCD and global fear constructs that might be directly targeted in treatment.

    Immunological factors are increasingly recognized as being important in a range of neuropsychiatric disorders. We aimed to summarize the disperse and often conflicting literature on the potential association between autoimmune diseases (ADs) and obsessive-compulsive disorder (OCD) and tic disorders. We searched PubMed, EMBASE, and PsycINFO for original studies evaluating the relationship between ADs and OCD/tic disorders until July, 13th 2016. Seventy-four studies met inclusion criteria. Overall, the studies were of limited methodological quality. Rates of OCD were higher in rheumatic fever patients who were also affected by its neurological manifestation, Sydenham's chorea. The literature on other ADs was scarce and the findings inconclusive. Few studies examined the association between ADs and tic disorders. A handful of family studies reported elevated rates of ADs in first-degree relatives of individuals with OCD/tic disorders, and vice versa, potentially suggesting shared genetic and/or environmental mechanisms. In conclusion, at present, there is modest evidence for a possible association and familial co-aggregation between ADs and OCD/tic disorders. We offer some suggestions for future research.

    2016-08-01

    Obsessive-compulsive disorder (OCD) has been recognized as mainly characterized by compulsivity rather than anxiety and, therefore, was removed from the anxiety disorders chapter and given its own in both the American Psychiatric Association (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the Beta Draft Version of the 11th revision of the World Health Organization (WHO) International Classification of Diseases (ICD-11). This revised clustering is based on increasing evidence of common affected neurocircuits between disorders, differently from previous classification systems based on interrater agreement. In this article, we focus on the classification of obsessive-compulsive and related disorders (OCRDs), examining the differences in approach adopted by these 2 nosological systems, with particular attention to the proposed changes in the forthcoming ICD-11. At this stage, notable differences in the ICD classification are emerging from the previous revision, apparently converging toward a reformulation of OCRDs that is closer to the DSM-5.

    Obsessive-compulsive disorder (OCD) has a heterogeneous and complex phenomenological picture, characterized by different symptom dimensions and comorbid psychiatric disorders, which frequently co-occur or are replaced by others over the illness course. To date, very few studies have investigated the associations between specific OCD symptom dimensions and comorbid disorders. Cross-sectional, multicenter clinical study with 1001 well-characterized OCD patients recruited within the Brazilian Research Consortium on Obsessive-Compulsive and Related Disorders. The primary instruments were the Dimensional Yale-Brown Obsessive Compulsive Scale (DY-BOCS) and the Structured Clinical Interview for DSM-IV Axis I Disorders. Bivariate analyses between symptom dimensions and comorbidities were followed by logistic regression. The most common comorbidities among participants (56.8% females) were major depression (56.4%), social phobia (34.6%), generalized anxiety disorder (34.3%), and specific phobia (31.4%). The aggressive dimension was independently associated with posttraumatic stress disorder (PTSD), separation anxiety disorder, any impulse-control disorder and skin picking; the sexual-religious dimension was associated with mood disorders, panic disorder/agoraphobia, social phobia, separation anxiety disorder, non-paraphilic sexual disorder, any somatoform disorder, body dysmorphic disorder and tic disorders; the contamination-cleaning dimension was related to hypochondriasis; and the hoarding dimension was associated with depressive disorders, specific phobia, PTSD, impulse control disorders (compulsive buying, skin picking, internet use), ADHD and tic disorders. The symmetry-ordering dimension was not independently associated with any comorbidity. Cross-sectional design; participants from only tertiary mental health services; personality disorders not investigated. Different OCD dimensions presented some specific associations with comorbid disorders, which may influence

    The study aimed to compare male and female patients with obsessive-compulsive disorder (OCD) across symptom dimensions, clinical course and comorbidity. A cross-sectional study was undertaken with 858 adult OCD patients (DSM-IV) from the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. Patients were evaluated using structured interviews, including the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) and the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I). The sample was composed of 504 women (58.7%) and 354 men (41.3%) with a mean age of 35.4 years-old (range: 18-77). Men were younger, more frequently single and presented more tics, social phobia and alcohol use disorders. Among men, symptom interference occurred earlier and symptoms of the sexual/religious dimension were more common and more severe. Conversely, women were more likely to present symptoms of the aggressive, contamination/cleaning and hoarding dimension and comorbidity with specific phobias, anorexia nervosa, bulimia, trichotillomania, skin picking and "compulsive" buying. In the logistic regression, female gender remained independently associated with the aggressive and contamination/cleaning dimensions. In both genders the aggressive dimension remained associated with comorbid post-traumatic stress disorder, the sexual/religious dimension with major depression and the hoarding dimension with tic disorders. Gender seems to be relevant in the determination of OCD clinical presentation and course and should be considered an important aspect when defining more homogeneous OCD subgroups.

    Overestimation of threat (OET) has been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). The present study deconstructed this complex concept and looked for specific deviances in OCD relative to controls. A total of 46 participants with OCD and 51 nonclinical controls were asked: (a) to estimate the incidence rate for 20 events relating to washing, checking, positive, or negative incidents. Furthermore, they were required (b) to assess their personal vulnerability to experience each event type, and (c) to judge the degree of accompanying worry. Later, participants were confronted with the correct statistics and asked (d) to rate their degree of worry versus relief. OCD participants did not provide higher estimates for OCD-related events than healthy participants, thus rendering a knowledge deficit unlikely. The usual unrealistic optimism bias was found in both groups but was markedly attenuated in OCD participants. OCD-related events worried OCD participants more than controls. Confrontation with the correct statistics appeased OCD participants less than healthy participants. Even in the case of large initial overestimations for OCD-related events, correct information appeased OCD participants significantly less than healthy participants. Our results suggest that OCD is not associated with a knowledge deficit regarding OCD-related events but that patients feel personally more vulnerable than nonclinical controls.

    Obsessive-compulsive disorder (OCD) is characterized by repetitive intrusive thoughts and compulsive time-consuming behaviors classified into three to five distinct symptom dimensions including: (1) aggressive/somatic obsessions with checking compulsions; (2) contamination concerns with washing compulsions; (3) symmetry obsessions with counting/ordering compulsions; (4) hoarding obsessions with collecting compulsions; and (5) sexual/religious concerns. Phenomenologically, OCD could be thought of as the irruption of internal signals centered on the erroneous perception that "something is wrong" in a specific situation. This generates severe anxiety, leading to recurrent behaviors aimed at reducing the emotional tension. In this paper, we examine how the abnormalities in brain activity reported in OCD can be interpreted in the light of physiology after consideration of various approaches (phenomenology, neuropsychology, neuroimmunology and neuroimagery) that contribute to proposing the central role of several cortical and subcortical regions, especially the orbitofrontal cortex (OFC), the anterior cingulate cortex (ACC), the dorsolateral prefrontal cortex (DLPC), the head of the caudate nucleus and the thalamus. The OFC is involved in the significance attributed to the consequences of action, thereby subserving decision-making, whereas the ACC is particularly activated in situations in which there are conflicting options and a high likelihood of making an error. The DLPC plays a critical part in the cognitive processing of relevant information. This cortical information is then integrated by the caudate nucleus, which controls behavioral programs. A dysfunction of these networks at one or several stages will result in the emergence and maintenance of repetitive thoughts and characteristic OCD behavior. Copyright 2004 Elsevier Ltd.

    Internet use is pervasive in many cultures. Little is known about the impact of obsessive-compulsive personality disorder (OCPD) symptoms on impulsive and compulsive psychopathologies in people who use the Internet. Adult Internet users (N = 1,323) completed an online questionnaire quantifying OCPD symptoms, likely occurrence of select mental disorders (obsessive-compulsive disorder, attention-deficit/hyperactivity disorder [ADHD], problematic Internet use, generalized anxiety disorder), and personality questionnaires of impulsivity and compulsivity. Predictors of the presence of OCPD symptoms (endorsement of at least 4 of 8 DSM-5 criteria) were identified using binary logistic regression. In regression (P OCPD symptoms were significantly associated with (in order of decreasing effect size) lower non-planning impulsivity, higher ADHD symptoms, problematic Internet use, avoidant personality disorder, female sex, generalized anxiety disorder, and some types of compulsions (checking, dressing/washing). These data suggest that OCPD symptoms, defined in terms of at least 4 of 8 DSM criteria being met, are common in Internet users. OCPD symptoms were associated with considerably higher levels of psychopathology relating to both impulsive (ADHD) and compulsive (OCD-related and problematic Internet use) disorders. These data merit replication and extension using standard in-person clinical assessments, because the current study relied on self-report over the Internet.

    Obsessive-compulsive disorder (OCD) is a leading cause of disability worldwide, however for reasons that are poorly understood ethnic minority groups are not well represented in clinical research studies. Thus, although African Americans experience equivalent rates of OCD according to epidemiological surveys, the generalizability of findings from clinical trials remains unknown. Research designed to improve identification, assessment and treatment of OCD is an important public health priority. The purpose of this study is to report outreach methods used to recruit African American adults for participation in an OCD research study. A variety of methods were employed, including radio advertisements, public transportation advertising, community outreach, and online advertising. A total of 83 African American adult participants were recruited over a 9.5 month period at the University of Pennsylvania in Philadelphia, and given comprehensive psychiatric assessments. African Americans with OCD symptoms were reliably identified and assessed, for a total of 75 with lifetime OCD (4 past and 71 current diagnoses). There was variability in the success and cost effectiveness of study recruitment methods. Radio ads were the most expensive means of recruitment, newspaper ads accounted for the largest number of eligible participants, and no cost methods such as Craig's List and word of mouth were also effective. The authors conclude that, with focused efforts, there are many effective methods for recruiting African Americans with OCD. Guidelines for recruitment are discussed, with a focus on cultural considerations. Copyright © 2011 Elsevier Inc. All rights reserved.

    The current study is a preliminary test of a virtual reality (VR) anxiety-provoking tool using a sample of participants with obsessive-compulsive disorder (OCD). The tasks were administrated to 33 participants with OCD and 30 healthy control participants. In the VR task, participants navigated through a virtual environment using a joystick and head-mounted display. The virtual environment consisted of three phases: training, distraction, and the main task. After the training and distraction phases, participants were allowed to check (a common OCD behavior) freely, as they would in the real world, and a visual analogy scale of anxiety was recorded during VR. Participants' anxiety in the virtual environment was measured with a validated measure of psychiatric symptoms and functions and analyzed with a VR questionnaire. Results revealed that those with OCD had significantly higher anxiety in the virtual environment than did healthy controls, and the decreased ratio of anxiety in participants with OCD was also higher than that of healthy controls. Moreover, the degree of anxiety of an individual with OCD was positively correlated with a his or her symptom score and immersive tendency score. These results suggest the possibility that VR technology has a value as an anxiety-provoking or treatment tool for OCD.

    Full Text Available Aim. Recent research implicated place of an immune mechanism in the pathophysiology of obsessive-compulsive disorder (OCD. Despite increasing evidence involvement of cytokine release in OCD, results of the studies are inconsistent. The aim of this study was to evaluate the plasma levels of the cytokines; tumor necrosis factor-alpha (TNF-α and interleukin-6 (IL-6 in OCD patients. Methods. Plasma concentrations of TNF-α and IL-6 were measured in 31 drug-free outpatients with OCD, and 31-year age and sex-matched healthy controls. TNF-α and IL-6 concentrations in blood were determined by enzyme-linked immunosorbent assay (ELISA. Results. Both TNF-α and IL-6 levels showed statistically significant increases in OCD patients compared to controls (P<.000, P<.001, resp.. In addition, the age of onset was negatively correlated with TNF-α level (r=−.402, P=.025 and duration of illness was weakly correlated with IL-6 levels (r:.357; P:.048 in patients group. Conclusion. OCD patients showed increases in TNF-α and IL-6 levels compared to the healthy controls. This study provides evidence for alterations in the proinflamatory cytokines which suggest the involvement of the immune system in the pathophysiology of OCD.

    Obsessive-compulsive disorder (OCD) is a neuropsychiatric condition that affects men and women equally, but with a sexually dimorphic pattern of development. Reproductive cycle events can influence symptom severity of OCD in females, indicating that ovarian hormones or their interaction with distinct neurotransmitter systems may play a role in OCD pathophysiology. Clinical studies and animal models have confirmed the importance of the serotonergic (5-HT) system in the neurobiology and treatment of OCD. Accordingly, the non-selective 5-HT2c agonist, meta-chlorophenylpiperazine (mCPP), exacerbates symptoms in untreated OCD patients. In rodents, it evokes repetitive behaviors that engage brain areas that are homologous with those found to be dysfunctional in OCD patients. These regions, including the medial prefrontal and anterior cingulate cortices, are also involved in fear inhibition, which is impaired in OCD. Here, we treated rats with mCPP (0.5 and 3.0 mg/kg) to evaluate its influence on self-grooming behavior and assess potential fear extinction retention deficits, taking into account sex differences and females' estrous cycle. We found that mCPP exacerbated grooming in male and female rats, irrespective of the estrous cycle phase. Fear extinction retention, however, was impaired only in females. Moreover, females undergoing fear extinction training during the metestrus/diestrus phases of the estrous cycle were more sensitive to the impairments induced by mCPP. Our results indicate that mCPP can induce OCD-like symptoms, exacerbating self-grooming and impairing fear extinction. It suggests that changes in 5-HT signaling through 5-HT2c receptors may have an important role in the OCD pathophysiology and that the influence of gonadal hormones in OCD should be further investigated.

    Full Text Available Abstract Background Many students who begin university at risky periods for OCD development cannot meet the new challenges successfully. They often seek help and apply to the university health center for psychiatric distress. We aimed to determine the prevalence and associated factors of Obsessive Compulsive Disorder (OCD at students of the Cukurova University in this cross sectional study. Methods This study was performed in the Cukurova University Faculty of Education with a population of 5500 students; the representative sample size for detecting the OCD prevalence was calculated to be 800. After collecting sociodemographic data, we questioned the students for associated factors of OCD. The General Health Questionnaire-12 (GHQ-12 and Composite International Diagnostic Interview (CIDI, Section K were used for psychiatric evaluation. Logistic regression analysis was performed to evaluate the linkage between OCD and associated factors. Results A total of 804 university students were included in this study. The GHQ-12-positive students (241 students, 29.9% were interviewed using Section K of the CIDI (222 students, 27.6%. OCD was diagnosed in 33 (4.2% students. The Logistic regression analysis of the data showed significant associations between OCD and male gender (p:0.036, living on government dormitory (p: 0.003, living on students' house/parental house (p:0.006, having private room in the parental house (p:0.055 and verbal abuse in the family (p:0.006. Conclusion This study demonstrates a higher prevalence of OCD among a group of university students compared to other prevalence studies of OCD in Turkish society. Furthermore, our findings also suggest relationships between OCD and sociodemographic factors, as well as other environmental stress factors.

    Objective To examine family conflict, parental blame, and poor family cohesion as predictors of treatment outcome for youth receiving family-focused cognitive behavioral therapy (FCBT) for obsessive compulsive disorder (OCD). Methods We analyzed data from a sample of youth who were randomized to FCBT (n = 49; 59% male; mean age = 12.43 years) as part of a larger randomized clinical trial. Youngsters and their families were assessed by an independent evaluator (IE) pre- and post- FCBT using a standardized battery of measures evaluating family functioning and OCD symptom severity. Family conflict and cohesion were measured via parent self-report on the Family Environment Scale (FES; Moos & Moos, 1994) and parental blame was measured using parent self-report on the Parental Attitudes and Behaviors Scale (PABS; Peris, 2008b). Symptom severity was rated by IE’s using the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS; Scahill et al., 1997). Results Families with lower levels of parental blame and family conflict and higher levels of family cohesion at baseline were more likely to have a child who responded to FCBT treatment even after adjusting for baseline symptom severity compared to families who endorsed higher levels of dysfunction prior to treatment. In analyses using both categorical and continuous outcome measures, higher levels of family dysfunction and difficulty in higher number of domains of family functioning were associated with lower rates of treatment response. In addition, changes in family cohesion predicted response to FCBT controlling for baseline symptom severity. Conclusions Findings speak to the role of the family in treatment for childhood OCD and highlight potential targets for future family interventions. PMID:22309471

    Full Text Available Objective:Evidence suggests that early-onset obsessive-compulsive disorder (OCD is an etiologically distinct subtype of OCD. The objective of the present work was to search for neurocognitive endophenotypes of early-onset OCD based on assessments of attention, memory, and executive function in patients with the disorder and their unaffected siblings.Methods:We compared the performance of 40 adult patients with early-onset OCD, 40 of their unaffected siblings, and 40 unrelated healthy controls on a neuropsychological battery designed for this study. We searched for associations among test performance, demographic variables (age, sex and years of education and clinical symptoms of early-onset OCD.Results:Patients performed significantly worse than healthy controls on the Tower of Hanoi, and the Stroop and Wisconsin tests, indicating impairments in planning, mental flexibility and inhibitory control. The performance of the unaffected first-degree siblings of patients with early-onset OCD on the Stroop and Wisconsin tests also differed from that of healthy controls. Symptom severity in early-onset OCD was strongly correlated with performance on the Tower of Hanoi.Conclusions:Our findings support the existence of specific executive function deficits in patients with early-onset OCD. Relatives presented an intermediate phenotype between patients and controls, suggesting that executive functions such as mental flexibility and response inhibition may be considered candidate endophenotypes of early-onset OCD.

    Distressing symptom-related anxiety is difficult to study in obsessive-compulsive disorder (OCD) due to the disorder's heterogeneity. Our aim was to develop and validate a set of pictures and films comprising a variety of prominent OCD triggers that can be used for individually tailored symptom provocation in experimental studies. In a two-staged production procedure a large pool of OCD triggers and neutral contents was produced and preselected by three psychotherapists specialized in OCD. A sample of 13 OCD patients and 13 controls rated their anxiety, aversiveness and arousal during exposure to OCD-relevant, aversive and neutral control stimuli. Our findings demonstrate differences between the responses of patients and controls to OCD triggers only. Symptom-related anxiety was stronger in response to dynamic compared with static OCD-relevant stimuli. Due to the small number of 13 patients included in the study, only tentative conclusions can be drawn and this study merely provides a first step of validation. These standardized sets constitute valuable tools that can be used in experimental studies on the brain correlates of OCD symptoms and for the study of therapeutic interventions in order to contribute to future developments in the field.

    Borderline personality disorder, conversion disorder and obsessive compulsive disorder frequently have dissociative symptoms. The literature has demonstrated that the level of dissociation might be correlated with the severity of obsessive compulsive disorder (OCD) and that those not responding to treatment had high dissociative symptoms. The structured clinical interview for DSM-IV dissociative disorders, dissociation questionnaire, somatoform dissociation questionnaire and dissociative experiences scale can be used for screening dissociative symptoms and detecting dissociative disorders in patients with OCD. However, a history of neglect and abuse during childhood is linked to a risk factor in the pathogenesis of dissociative psychopathology in adults. The childhood trauma questionnaire-53 and childhood trauma questionnaire-40 can be used for this purpose. Clinicians should not fail to notice the hidden dissociative symptoms and childhood traumatic experiences in OCD cases with severe symptoms that are resistant to treatment. Symptom screening and diagnostic tools used for this purpose should be known. Knowing how to treat these pathologies in patients who are diagnosed with OCD can be crucial.

    Abstract The concept of comorbidity between attention deficit/hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD) has been discussed for two decades. No review, however, has examined this question in light of the stark contrast in disorder-specific phenomenology and neurobiology. We review reported prevalence rates and the methodological, phenomenological, and theoretical issues concerning concomitant ADHD-OCD. Reported co-occurrence rates are highly inconsistent in the literature. Studies aimed at examining the potential for comorbidity have suffered from various methodological problems, including the existence of very few community samples, highly variable exclusionary criteria, and possible clinical misinterpretation of symptoms. Despite numerous studies suggesting an ADHD-OCD comorbidity, thus far etiological (i.e., genetic) backing has been provided only for a pediatric comorbidity. Additionally, inflated rates of ADHD-OCD co-occurrence may be mediated by the presence of tic disorders, and evidence of impaired neuronal maturational processes in pediatric OCD may lead to possibly transient phenotypical expressions that resemble ADHD symptomatology. Thus, clinicians are encouraged to consider the possibility that ADHD-like symptoms resulting from OCD-specific symptomatology may be misdiagnosed as ADHD. This suggestion may account for the lower co-occurrence rates reported in adolescents and adults and for the lack of a theoretical account for comorbidity in these age groups. Existing literature is summarized and critically reviewed, and recommendations are made for future research. PMID:26052877

    While there is a plethora of evidence for the efficacy of cognitive-behavioural therapy (CBT) in obsessive-compulsive disorder (OCD), studies on change factors of the therapeutic process that account for this success are scarce. In the present study, 155 participants with primary OCD were investigated during CBT inpatient treatment. The Yale-Brown Obsessive-Compulsive Scale-SR served as a measure of symptom severity. In addition, the following process change factors were measured: therapeutic relationship, experience of self-esteem during therapy, experience of mastery, problem actualization and clarification. All variables were assessed on a weekly basis for seven weeks. Linear mixed growth curve analyses were conducted to model the decrease of symptoms over time and to analyse whether the change factors predicted symptom reduction. The analyses revealed a linear decrease of symptoms with high inter-individual variation. Results further showed that increase in self-esteem and mastery experiences as well as the initial score on mastery experience and clarification predicted decrease on the Y-BOCS. We conclude that CBT therapists should focus on clarification in the very first sessions, and try to boost self-esteem and self-efficacy, which is related to mastery, throughout the treatment of OCD.

    There are reasons for thinking that obsessive-compulsive disorder (OCD) and drug dependence, although conventionally distinct diagnostic categories, might share important cognitive and neurobiological substrates. We tested this hypothesis directly by comparing brain functional connectivity measures between patients with OCD, stimulant dependent individuals (SDIs; many of whom were non-dependent users of other recreational drugs) and healthy volunteers. We measured functional connectivity between each possible pair of 506 brain regional functional MRI time series representing low frequency (0.03-0.06 Hz) spontaneous brain hemodynamics in healthy volunteers (N=18), patients with OCD (N=18) and SDIs (N=18). We used permutation tests to identify i) brain regions where strength of connectivity was significantly different in both patient groups compared to healthy volunteers; and ii) brain regions and connections which had significantly different functional connectivity between patient groups. We found that functional connectivity of right inferior and superior orbitofrontal cortex (OFC) was abnormally reduced in both disorders. Whether diagnosed as OCD or SDI, patients with higher scores on measures of compulsive symptom severity showed greater reductions of right orbitofrontal connectivity. Functional connections specifically between OFC and dorsal medial pre-motor and cingulate cortex were attenuated in both patient groups. However, patients with OCD demonstrated more severe and extensive reductions of functional connectivity compared to SDIs. OCD and stimulant dependence are not identical at the level of brain functional systems but they have some important abnormalities in common compared with healthy volunteers. Orbitofrontal connectivity may serve as a human brain systems biomarker for compulsivity across diagnostic categories. Copyright © 2011 Elsevier Inc. All rights reserved.

    Depression frequently co-occurs with paediatric obsessive-compulsive disorder (OCD), yet the clinical correlates and impact of depression on CBT outcomes remain unclear. The prevalence and clinical correlates of depression were examined in a paediatric specialist OCD-clinic sample (N = 295; Mean = 15 [7 - 18] years, 42 % female), using both dimensional (Beck Depression Inventory-youth; n = 261) and diagnostic (Development and Wellbeing Assessment; n = 127) measures of depression. The impact of depressive symptoms and suspected disorders on post-treatment OCD severity was examined in a sub-sample who received CBT, with or without SSRI medication (N = 100). Fifty-one per-cent of patients reported moderately or extremely elevated depressive symptoms and 26 % (95 % CI: 18 - 34) met criteria for a suspected depressive disorder. Depressive symptoms and depressive disorders were associated with worse OCD symptom severity and global functioning prior to CBT. Individuals with depression were more likely to be female, have had a psychiatric inpatient admission and less likely to be attending school (ps depressive symptom severity significantly decreased after CBT. Depressive symptoms and depressive disorders predicted worse post-treatment OCD severity (βs = 0.19 and 0.26, ps Depression is common in paediatric OCD and is associated with more severe OCD and poorer functioning. However, depression severity decreases over the course of CBT for OCD and is not independently associated with worse outcomes, supporting the recommendation for treatment as usual in the presence of depressive symptoms.

    Full Text Available Few studies have explored the neurobiological basis of insight level in obsessive-compulsive disorder (OCD, though the salience network (SN has been implicated in insight deficits in schizophrenia. This study was then designed to investigate whether resting-state (rs functional connectivity (FC of SN was associated with insight level in OCD patients. We analyzed rs-functional magnetic resonance imaging (fMRI data from 21 OCD patients with good insight (OCD-GI, 19 OCD patients with poor insight (OCD-PI, and 24 healthy controls (HCs. Seed-based whole-brain FC and ROI (region of interest-wise connectivity analyses were performed with seeds/ROIs in the bilateral anterior insula (AI and dorsal anterior cingulate cortex (dACC. The right AI-right medial orbital frontal cortex (mOFC connectivity was found to be uniquely decreased in the OCD-PI group, and the value of this aberrant connectivity correlated with insight level in OCD patients. In addition, we found that the OCD-GI group had significantly increased right AI-left dACC connectivity within the SN, relative to HCs (overall trend for groups: OCD-GI > OCD-PI > HC. Our findings suggest that abnormal right AI-right mOFC FC may mediate insight deficits in OCD, perhaps due to impaired encoding and integration of self-evaluative information about OCD-related beliefs and behaviors. Our findings indicate a SN connectivity dissociation between OCD-GI and OCD-PI patients and support the notion of considering OCD-GI and OCD-PI as two distinct disorder subtypes.

    Full Text Available Background: Obsessive-compulsive disorder (OCD is a chronic disorder that strongly affects one's life and social, emotional, and occupational functioning. Due to the effect of religious beliefs on phenomenology of OCD, in this paper, we assess the effectiveness of religious cognitive behavioral therapy (CBT within 3 and 6 months follow-up. Materials and Methods: This study is a clinical trial with follow-ups which last 2 months consisting eight sessions of 1.5 h of religious CBT. The research is conducted in a group of 40, with pre- and post-test after 3 and 6 months. Used Yale-Brown OCD symptom scale, before, the end, after 3 months and after 6 months of intervention. Treatment is carried out by a psychiatrist and a clergyman through religious CBT. The trial is held in OCD clinic affiliated with Noor Hospital. Results are analyzed by ANOVA repeated measure with SPSS18. Results: The results showed a considerable decrease in OCD symptoms which remained almost persistent after 3 and 6 months (F = 3/54. P = 0/024. It also shows that religious CBT can leave substantial effect on OCD symptoms; permanency of this intervention after 3 and 6 months is noticeable (P < 0/001. In Conclusion this therapy could be helpful for OCD patients with religious content. Conclusion: RCBT have a positive effect on people with religious obsessive -compulsive.

    Full Text Available Obsessive compulsive disorder (OCD is a common disorder characterised by persistent and unwanted intrusive thoughts, images, and urges and repetitive behaviours or mental acts and can cause pervasive impairments. In Bangladesh, the prevalence of OCD among children is 2% which is higher than in previous reporting. This study was aimed at looking into the type, frequency, and severity of symptoms of OCD and comorbidity among children and adolescents. A consecutive 60 OCD cases from a child mental health service with age range of 5–18 years were recruited and divided into below and above 12 years of age group. The assessment was carried out using standardized Bangla version of Development and Wellbeing Assessment and Children’s Yale-Brown Obsessive Compulsive Scale was administered. Of the obsession, contamination was the highest followed by doubt, and of the compulsion, washing/cleaning was the highest followed by checking, repeating, and ordering rituals. More than half of the subjects had severe OCD and comorbidity was present in 58% subjects. Specific phobia, social phobia, major depressive disorder, and tic disorder were more prevalent. These symptoms and comorbidity profile can serve the baseline data for a country like Bangladesh and further large scale study would better generalize the study results.

    Attitudes towards risk are highly consequential in clinical disorders thought to be prone to "risky behavior", such as substance dependence, as well as those commonly associated with excessive risk aversion, such as obsessive-compulsive disorder (OCD) and hoarding disorder (HD). Moreover, it has recently been suggested that attitudes towards risk may serve as a behavioral biomarker for OCD. We investigated the risk preferences of participants with OCD and HD using a novel adaptive task and a quantitative model from behavioral economics that decomposes risk preferences into outcome sensitivity and probability sensitivity. Contrary to expectation, compared to healthy controls, participants with OCD and HD exhibited less outcome sensitivity, implying less risk aversion in the standard economic framework. In addition, risk attitudes were strongly correlated with depression, hoarding, and compulsion scores, while compulsion (hoarding) scores were associated with more (less) "rational" risk preferences. These results demonstrate how fundamental attitudes towards risk relate to specific psychopathology and thereby contribute to our understanding of the cognitive manifestations of mental disorders. In addition, our findings indicate that the conclusion made in recent work that decision making under risk is unaltered in OCD is premature. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available The research aims to establish the main characteristics of subjects prone to compulsive overeating (experimental group, EG, and the differences between them and the girls who are not prone to any kind of eating disorders (control group, CG. The results of the research are in accordance with the expectations. Girls from the EG exhibit personality characteristics which are signifficantly different from the girls in the CG. These characteristics may be either possible predispositions for development of overeating, or they may already be the consequences of the girls' struggles with overeating and their perception of being overweight. The responses given by the girls from the EG confirm the generaly accepted characteristics of overeating individuals. It can be said that the girls from the ES show the pre-clinical picture of overeating, while some of them have already developed the clinical picture. The results of the research strongly support the view that overeating must be defined as a form of eating disorder just as important as anorexia and bulimia nervosa.

    Background Temporal discounting refers to the tendency for rewards to lose value as the expected delay to receipt increases. Individuals with anorexia nervosa (AN) have been found to show reduced temporal discounting rates, indicating a greater preference for delayed rewards compared to healthy peers. Obsessive–compulsive disorder (OCD) and social anxiety disorder (SAD) commonly co-occur with AN, and anxiety has been related to development and prognosis of AN. We examined whether reduced temporal discounting is present across these potentially related disorders, and explored the relationship between temporal discounting and anxiety trans-diagnostically. Methods One hundred ninety six individuals (75 healthy controls (HC); 50 OCD; 27 AN; 44 SAD) completed two temporal discounting tasks in which they chose between smaller-sooner and larger-later monetary rewards. Two measures of discounting—discount rate and discount factor—were compared between diagnostic groups, and associations with anxious traits were examined. Results Individuals with AN showed decreased temporal discounting compared to HC. OCD and SAD groups did not differ significantly from HC. Across the sample, anxiety was associated with decreased discounting; more anxious individuals showed a greater preference for delayed reward. Conclusions We replicated the findings that individuals with AN show an increased preference for delayed reward relative to HC and that individuals with OCD do not differ from HC. We also showed that individuals with SAD do not differ from HC in discounting. Across this large sample, two measures of anxious temperament were associated with temporal discounting. These data raise new questions about the relationship between this dimensional trait and psychopathology. PMID:28009473

    Full Text Available streptococcus infections in the development of tic and obsessive compulsive disorders (OCD is controversial. The autoimmune hypothesis states that during infection, formation of autoantibodies leads to an autoimmune disorder, which in turn results in movement disorders, tic disorders and/or OCD. In order to test this hypothesis, we assayed these antibodies in children and adolescents diagnosed with tic disorders and/or OCD.Material and Methods: Children and adolescents who were diagnosed with either tic disorders or OCD according to DSM-IV criteria (n=28, were compared with healthy controls (n=15 having similar age and gender characteristics. Regardless of a streptococcus infection history, serum samples of all patients and controls underwent antinuclear, cytoskeletal, and antineuronal antibody assay using indirect immunofluorescence.Results: The rates of antinuclear antibody positivity were 21% and 20% in the patient and control groups respectively (p>0.05. Antineuronal antibody was positive in 2 (7% of 28 patients versus in 1 (6% of 15 controls (p>0.05.Conclusion: These results suggest that such antibodies may not be involved in the pathogenesis of tic disorders/OCD.

    Adult patients with Obsessive Compulsive Disorder (OCD) have been shown to have gray matter (GM) volume differences from healthy controls in multiple regions - the orbitofrontal cortex (OFC), anterior cingulate cortex (ACC), medial frontal gyri (MFG), striatum, thalamus, and superior parietal lobule. However, there is paucity of data with regard to juvenile OCD. Hence, we examined GM volume differences between juvenile OCD patients and matched healthy controls using voxel based morphometry (VBM) with the above apriori regions of interest. Fifteen right handed juvenile patients with OCD and age- sex- handedness- matched healthy controls were recruited after administering the Mini International Neuropsychiatric Interview-KID and the Children's Yale-Brown Obsessive Compulsive Scale, and scanned using a 3 Tesla magnetic resonance imaging scanner. VBM methodology was followed. In comparison with healthy controls, patients had significantly smaller GM volumes in left ACC. YBOCS total score (current) showed significant negative correlation with GM volumes in bilateral OFC, and left superior parietal lobule. These findings while reiterating the important role of the orbito-fronto-striatal circuitry, also implicate in the parietal lobe - especially the superior parietal lobule as an important structure involved in the pathogenesis of OCD.

    Full Text Available Background: There is paucity of information on the relationship of quality of life (QOL in obsessive compulsive disorder (OCD and dysthymic disorder (DD with disability grade in India. Aim: To assess the relation of QOL with disability level in OCD and DD. Materials and Methods: This hospital based study was conducted in a medical institution in Davanagere, Karnataka, India. Data was collected by using Diagnostic and Statistical Manual IV Text Revision (DSM IV TR criteria, WHO QOL BREF and IDEAS. Relationship between disability grade and QOL was assessed by independent sample t test. Results: Mild disabled OCD patients had a significantly better QOL in the Q1 domain i.e. perception on quality of life as compared to moderately disabled patients ( P 0.05. But, QOL score in physical domain showed significant difference across disability grades (56.00, SD = 6.89; 48.50, SD = 12.28 in DD, but not in other domains. Conclusion: Perception of QOL is better in those with mild disability in OCD, but in DD, physical domain of QOL score is more in mild disability compared to moderate disability.

    The neurocognitive deficits that underlie the unique features of obsessive-compulsive disorder (OCD) are not yet completely understood. This paper reviews the main neuropsychological findings in memory and executive functioning in this disorder, and examines a number of challenges facing this area of research. A selective review of the neuropsychological literature on OCD was conducted using MEDLINE and drawing on literature known to the authors. The neuropsychological profile of OCD appears to be one of primary executive dysfunction. Although memory functioning may be affected, these deficits appear secondary to an executive failure of organizational strategies during encoding. On tasks of executive functioning patients with OCD demonstrate increased response latencies, perseveration of responses, and difficulties utilizing feedback to adapt to change. A statistical meta-analysis was not performed and only the cognitive domains of memory and executive functioning were examined. Given the prominence of chronic doubt and indecision in clinical settings, it is surprising that decision making as a cognitive construct as related to OCD has not received greater attention in the neuropsychological literature. On the basis of emerging literature we suggest that it is a potential area of dysfunction and one that warrants further investigation as it may assist in enhancing our understanding of the pathophysiology of OCD.

    Both obsessive-compulsive disorder (OCD) and social phobia are common in community and clinical settings, and it should be expected that a proportion of patients with one of these conditions will also fulfill either current or lifetime criteria for the other condition. However, comorbid social phobia is more common among patients with a primary diagnosis of OCD than is comorbid OCD in patients with a primary diagnosis of social phobia. This article explores the extent of the association of OCD and social phobia in epidemiological studies, and examines the possible role of underlying depression and other disorders in mediating the appearance of the comorbid condition. Although there have been no published randomized controlled trials in patients with this particular pattern of co-morbidity, it seems sensible to adopt pharmacologic and psychologic treatment approaches which have been found efficacious in both OCD and social phobia. Pharmacologic management therefore centers on first-line treatment with a selective serotonin reuptake inhibitor. Psychologic intervention should draw on the range of cognitive and behavioral approaches required for optimal outcomes in OCD and social phobia, as discrete conditions.

    Thought-action fusion (TAF) refers to the tendency to assume incorrect causal relationship between one's own thoughts and external reality, in which, thoughts and actions are treated as equivalents. This construct is present to development and maintenance of many psychological disorders. The aim of the present study was to predict obsessive-compulsive disorder (OCD) and its types, and major depressive disorder (MDD) with TAF and its levels. Two groups, included 50 persons with OCD and MDD, respectively, were selected by convenience sampling method in private and governmental psychiatric centers in Ardabil, Iran. Then, they responded to Beck Depression Inventory, Padua Inventory and TAF scale. Data were analysed using multiple regressions analysis by stepwise method. TAF or its subtypes (moral TAF, likelihood-self TAF and likelihood-others TAF) can explain 14% of MDD variance (p < 0.01), 15% of OCD variance (p < 0.01), and 8-21% of OCD types variance (p < 0.05). Moral TAF had high levels in OCD and MDD. The construct of TAF is not specific factor for OCD, and it is present in MDD, too. None.

However, although many studies have investigated event-related potentials (ERPs in patients with OCD compared with healthy control subjects, it is currently unknown whether ERP changes reflect pharmacological and psychotherapeutic effects. As such, the current study examined the neurocognitive components of OCD to elucidate the pathophysiological abnormalities involved in the disorder, including the frontal-subcortical circuits.Methods: The Yale-Brown Obsessive-Compulsive Scale was used to evaluate 14 adult patients with OCD. The present study also included ten age-, sex-, and IQ-matched controls. The P300 and mismatch negativity (MMN components during an auditory oddball task at baseline for both groups and after 1 year of treatment for patients with OCD were measured.Results: Compared with controls, P300 amplitude was attenuated in the OCD group at Cz and C4 at baseline. Pharmacotherapy and psychotherapy treatment for 1 year reduced OCD symptomology. P300 amplitude after 1 year of treatment was significantly increased, indicating normalization compared with baseline at Fz, Cz, C3, and C4. We found no differences in P300 latency, MMN amplitude, or MMN latency between baseline and after one year of treatment.Conclusion: ERPs may be a useful tool for evaluating pharmacological and cognitive behavioral therapy in adult patients with OCD.

    Obsessive compulsive personality disorder (OCPD) is characterized by perfectionism, need for control, and cognitive rigidity. Currently, little neuropsychological data exist on this condition, though emerging evidence does suggest that disorders marked by compulsivity, including obsessive-compulsive disorder (OCD), are associated with impairment in cognitive flexibility and executive planning on neurocognitive tasks. The current study investigated the neurocognitive profile in a nonclinical community-based sample of people fulfilling diagnostic criteria for OCPD in the absence of major psychiatric comorbidity. Twenty-one nonclinical subjects who fulfilled Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for OCPD were compared with 15 healthy controls on selected clinical and neurocognitive tasks. OCPD was measured using the Compulsive Personality Assessment Scale (CPAS). Participants completed tests from the Cambridge Automated Neuropsychological Test Battery including tests of set shifting (Intra-Extra Dimensional [IED] Set Shifting) executive planning (Stockings of Cambridge [SOC]), and decision making (Cambridge Gamble Task [CGT]). The OCPD group made significantly more IED-ED shift errors and total shift errors, and also showed longer mean initial thinking time on the SOC at moderate levels of difficulty. No differences emerged on the CGT. Nonclinical cases of OCPD showed significant cognitive inflexibility coupled with executive planning deficits, whereas decision-making remained intact. This profile of impairment overlaps with that of OCD and implies that common neuropsychological changes affect individuals with these disorders.

    The statistical estimates of the prevalence of Obsessive Compulsive Disorder (OCD) in the general population have increased dramatically in recent years. "Blasphemous" obsessions and religious compulsions dominate the clinical picture of many sufferers of OCD. Freud proposed that religion might be a contributing factor for many patients with mental illness. He hedged, however, that observation--something that many of his followers have not done. Others have noted the pathoplasticity of strict religious upbringing and images of God as vindictive or otherwise harsh. Only recently--since the 1970s--has much clinical attention been focused on this disorder by the other disciplines within the mental health community. The church, however, is ahead of the curve in diagnosis and treatment of scrupulosity. It has long been a concern for pastoral counselors--particularly pre-Vatican II Roman Catholic priests. Pathological religion influences OCD and pastoral counseling, the author proposes, can contributes to recovery.

    Individuals with body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD) are categorized within the same major diagnostic group and both show regional brain hyperactivity in the orbitofrontal cortex (OFC) and the basal ganglia during symptom provocation. While recent studies revealed that degree connectivity of these areas is abnormally high in OCD and positively correlates with symptom severity, no study has investigated degree connectivity in BDD. We used functional magnetic resonance imaging (fMRI) to compare the local and distant degree of functional connectivity in all brain areas between 28 unmedicated BDD participants and 28 demographically matched healthy controls during a face-processing task. Correlational analyses tested for associations between degree connectivity and symptom severity assessed by the BDD version of the Yale-Brown obsessive-compulsive scale (BDD-Y-BOCS). Reduced local amygdalar connectivity was found in participants with BDD. No differences in distant connectivity were found. BDD-Y-BOCS scores significantly correlated with the local connectivity of the posterior-lateral OFC, and distant connectivity of the posterior-lateral and post-central OFC, respectively. These findings represent preliminary evidence that individuals with BDD exhibit brain-behavioral associations related to obsessive thoughts and compulsive behaviors that are highly similar to correlations previously found in OCD, further underscoring their related pathophysiology. This relationship could be further elucidated through investigation of resting-state functional connectivity in BDD, ideally in direct comparison with OCD and other obsessive-compulsive and related disorders.

    This paper attempts to explore the brain activity of patients with obsessive-compulsive disorder (OCD) and its correlation with the disease at resting duration in patients with first-episode OCD, providing a forceful imaging basis for clinic diagnosis and pathogenesis of OCD. Twenty-six patients with first-episode OCD and 25 healthy controls (HC group; matched for age, sex, and education level) underwent functional magnetic resonance imaging (fMRI) scanning at resting state. Statistical parametric mapping 8, data processing assistant for resting-state fMRI analysis toolkit, and resting state fMRI data analysis toolkit packages were used to process the fMRI data on Matlab 2012a platform, and the difference of regional homogeneity (ReHo) values between the OCD group and HC group was detected with independent two-sample t -test. With age as a concomitant variable, the Pearson correlation analysis was adopted to study the correlation between the disease duration and ReHo value of whole brain. Compared with HC group, the ReHo values in OCD group were decreased in brain regions, including left thalamus, right thalamus, right paracentral lobule, right postcentral gyrus, and the ReHo value was increased in the left angular gyrus region. There was a negative correlation between disease duration and ReHo value in the bilateral orbitofrontal cortex (OFC). OCD is a multifactorial disease generally caused by abnormal activities of many brain regions at resting state. Worse brain activity of the OFC is related to the OCD duration, which provides a new insight to the pathogenesis of OCD.

    Visuospatial working memory (VSWM) is the ability of the brain to transiently store and manipulate visual information. VSWM deficiencies have been reported in obsessive-compulsive disorder (OCD), but not consistently, perhaps due to variability in task design and clinical patient factors. To explore this variability, this study assessed effects of the design factors task difficulty and executive organizational strategy and of the clinical factors gender, OCD symptom dimension, and duration of illness on VSWM in OCD. The CANTAB spatial working memory, spatial recognition memory, delayed matching to sample, and stop signal tasks were administered to 42 adult OCD patients and 42 age- and sex-matched healthy controls. Aims were to detect a possible VSWM deficit in the OCD sample, to evaluate influences of the above task and patient factors, to determine the specificity of the deficit to the visuospatial subdomain, and to examine effects of sustained attention as potential neurocognitive confound. We confirmed previous findings of a VSWM deficit in OCD that was more severe for greater memory load (task difficulty) and that was affected by task strategy (executive function). We failed to demonstrate significant deficits in neighboring or confounding neurocognitive subdomains (visual object recognition or visual object short-term memory, sustained attention). Notably, the VSWM deficit was only significant for female patients, adding to evidence for sexual dimorphism in OCD. Again as in prior work, more severe OCD symptoms in the symmetry dimension (but no other dimension) significantly negatively impacted VSWM. Duration of illness had no significant effect on VSWM. VSWM deficits in OCD appear more severe with higher task load and may be mediated through poor task strategy. Such deficits may present mainly in female patients and in (male and female) patients with symmetry symptoms.

    Full Text Available There is currently a lack of understanding how surgical menopause can influence obsessions, compulsions and associated affective and cognitive functions in female OCD patients. Early menopause in women due to surgical removal of ovaries not only causes dramatic hormonal changes, but also may induce affective and cognitive disorders. Here, we tested if surgical removal of ovaries (ovariectomy, OVX, which mimics surgical menopause in humans, would result in exacerbation of compulsive, affective and cognitive behaviors in mice strains that exhibit a spontaneous compulsive-like phenotype. Female mice from compulsive-like BIG, non-compulsive SMALL and randomly-bred Control strains were subjected to OVX or sham-surgery. After seven days animals were tested for nest building and marble burying to measure compulsive-like behavior. The elevated plus maze and open field tests measured anxiety-like behaviors, while memory was assessed by the novel object recognition. Acute OVX resulted in exacerbation of compulsive-like and anxiety-like behaviors in compulsive-like BIG mice. No significant effects of OVX were observed for the non-compulsive SMALL and Control strains. Object recognition memory was impaired in compulsive-like BIG female mice compared to the Control mice, without an effect of OVX on the BIG mice. We also tested whether 17 β-estradiol (E2 or progesterone (P4 could reverse the effects of OVX. E2, but not P4, attenuated the compulsive-like behaviors in compulsive-like BIG OVX female mice. The actions of the sex steroids on anxiety-like behaviors in OVX females were strain and behavioral test dependent. Altogether, our results indicate that already existing compulsions can be worsened during acute ovarian deprivation concomitant with exacerbation of affective behaviors and responses to hormonal intervention in OVX female mice can be influenced by genetic background.

  9. High-Dose Glycine Treatment of Refractory Obsessive-Compulsive Disorder and Body Dysmorphic Disorder in a 5-Year Period

    Full Text Available This paper describes an individual who was diagnosed with obsessive-compulsive disorder (OCD and body dysmorphic disorder (BDD at age 17 when education was discontinued. By age 19, he was housebound without social contacts except for parents. Adequate trials of three selective serotonin reuptake inhibitors, two with atypical neuroleptics, were ineffective. Major exacerbations following ear infections involving Group A -hemolytic streptococcus at ages 19 and 20 led to intravenous immune globulin therapy, which was also ineffective. At age 22, another severe exacerbation followed antibiotic treatment for H. pylori. This led to a hypothesis that postulates deficient signal transduction by the N-methyl-D-aspartate receptor (NMDAR. Treatment with glycine, an NMDAR coagonist, over 5 years led to robust reduction of OCD/BDD signs and symptoms except for partial relapses during treatment cessation. Education and social life were resumed and evidence suggests improved cognition. Our findings motivate further study of glycine treatment of OCD and BDD.

    Research among youths with obsessive compulsive disorder (OCD) has shown a significant relationship between illness severity, treatment outcome, and the family environment yet little work has been undertaken among the broader class of obsessive compulsive and related disorders (OCRDs) - Trichotillomania, body dysmorphic disorder (BDD), skin picking disorder (SPD), and hoarding. The aim of this study was to (1) review the family functioning literature among paediatric OCRDs, (2) address limitations to previous studies, and (3) highlight areas in need of further research. A review of the literature was conducted using several databases (i.e., Google Scholar, PubMed, ScienceDirect) and employing key search terms (e.g., 'family functioning', 'paediatric OCD'). The resultant articles examined several domains subsumed under the broader heading of family environment including parental mental health, parenting practices, family dynamics, family involvement with symptoms, and family emotional climate. The literature reviewed demonstrated a strong relationship between paediatric OCD and adverse family functioning (e.g., parental symptoms of anxiety and depression, family accommodation, family strain and stress, parental guilt and fear) in all identified domains. While family functioning research in paediatric HPD was relatively scant, research suggested similar familial dysfunction (e.g., limited independence, low family cohesion, family violence). Collectively, only 1 article, examining BDD, assessed family functioning within other OCRDs. This review supports the need for further research in the OCRDs. Limitations to the available literature and targeted suggestions for future research are discussed. The domains of family environment in this study indicate specific family functioning deficits that may serve as aetiological and/or maintenance factors in paediatric OCRDs, possibly contributing to the understanding of these complex disorders.

    Our aim was to investigate the impact of comorbid body dysmorphic disorder (BDD) on the response to sequential pharmacological trials in adult obsessive-compulsive disorder (OCD) patients. The sequential trial initially involved fluoxetine monotherapy followed by one of three randomized, add-on strategies: placebo, clomipramine or quetiapine. We included 138 patients in the initial phase of fluoxetine, up to 80 mg or the maximum tolerated dosage, for 12 weeks. We invited 70 non-responders to participate in the add-on trial; as 54 accepted, we allocated 18 to each treatment group and followed them for an additional 12 weeks. To evaluate the combined effects of sex, age, age at onset, initial severity, type of augmentation and BDD on the response to sequential treatments, we constructed a model using generalized estimating equations (GEE). Of the 39 patients who completed the study (OCD-BDD, n = 13; OCD-non-BDD, n = 26), the OCD-BDD patients were less likely to be classified as responders than the OCD-non-BDD patients (Pearson Chi-Square = 4.4; p = 0.036). In the GEE model, BDD was not significantly associated with a worse response to sequential treatments (z-robust = 1.77; p = 0.07). The predictive potential of BDD regarding sequential treatment strategies for OCD did not survive when the analyses were controlled for other clinical characteristics. © The Author(s) 2013.

    Significant differences in clinical profile and comorbidity patterns have been observed between "juvenile-onset" and "adult-onset" obsessive-compulsive disorder (OCD). There is little systematic research on onset of OCD after the fourth decade. The current study aims to compare the demographic, clinical, and comorbidity patterns of patients with "juvenile-onset" (OCD. Eight hundred two consecutive patients who consulted a specialty OCD clinic at a tertiary care hospital in India were evaluated with the Mini International Neuropsychiatric Interview, the Yale-Brown Obsessive-Compulsive Scale, and the Clinical Global Impression scale. 37.4%, 57.4%, and 5.2% of patients had juvenile-, adult-, and late-onset OCD, respectively. Late-onset OCD was associated with female gender (χ2=42, pOCD in first-degree relatives (χ2=20.4, pOCD was significantly associated with female gender, collecting compulsions, and less aggressive obsessions, in comparison with adult-onset OCD. In comparison with juvenile-onset, late-onset OCD was significantly associated with female gender, presence of precipitating factors, and less aggressive obsessions, sexual obsessions, and repeating compulsions. Late-onset OCD is characterized by female gender, lesser familial loading for OCD, and presence of precipitating factors, suggesting that it may have a distinct pathophysiology compared to juvenile- and adult-onset OCD. Systematic research is required to understand the family-genetic, neuropsychological, and neurobiological correlates of late-onset OCD.

    There have been reports of obsessive-compulsive disorder (OCD) patients with comorbid paraphilias. In this paper, two cases of comorbidity between OCD and transvestism are reported with the aim of discussing possible explanations for this association. Longitudinal case studies of two patients with OCD and tranvestism according to the DSM-IV were assessed using semi-structured interviews. Both patients presented with OCD and comorbid transvestism with different clinical features and treatment response. The case whose cross-dressing was more egodystonic responded better to treatment. It is possible that some cases of transvestism are OCD-related while others are more related to a gender identity disorder. A dimensional approach focusing on common phenomenological and neurobiological substrates is suggested as particularly useful for clinical management and future research of both disorders.

    Prior research supports the distinction between tic-related and non-tic-related obsessive-compulsive disorder (OCD) based on phenomenologic, etiologic, and neurobehavioral data. The present study examines whether response to psychosocial treatment differs in adolescents, depending on the presence of comorbid tics. Nineteen adolescents, 12-17 years of age, participated in 7-week, uncontrolled trial of group cognitive-behavioral treatment (CBT) for OCD. Eight of the patients had tic-related and eleven had non-tic-related OCD. The group CBT program included psycho-education, exposure and response prevention, cognitive strategies, and family involvement. Significant improvement was observed for all subjects on the Yale-Brown Obsessive Compulsive Scale ratings of obsessions, compulsions, and total OCD symptoms. Outcomes were similar for subjects with tic-related and non-tic-related OCD. These preliminary results suggest that the presence of comorbid tic disorders may not attenuate response to behavioral group treatment among adolescents. Copyright 2003 Wiley-Liss, Inc.

    Bulimia nervosa (BN) and obsessive-compulsive disorder (OCD) co-occur at greater rates than chance and may have shared mechanisms of dysfunction. One of these proposed mechanisms is a hyper-responsive aversive system as indicated by heightened startle response to aversive stimuli. The present study examined this hypothesis using 2 types of aversive stimuli: disorder specific (e.g., high-caloric food pictures for BN, contamination pictures for OCD) and nondisorder specific (e.g., knife). Temporal parameters of aversive responding were also examined by assessing startle response in anticipation of and following picture presentation. The sample consisted of 114 undergraduate women selected to have a broad range of BN and/or OCD symptomatology. OCD symptoms were associated with increased startle potentiation during the anticipation and presentation of contamination pictures, and BN symptoms were associated with increased startle potentiation during disorder-related contamination pictures (e.g., sink, toilet). BN symptoms were also associated with increased startle potentiation during and following the presentation of food pictures (though the former effect was only a trend). Additionally, the interaction of BN and OCD symptoms was associated with elevated startle responding during the presentation of contamination and threat stimuli. Overall, the present study provides evidence that BN and OCD symptoms are associated with heightened aversive responding to disorder-specific stimuli, and comorbid BN and OCD symptoms are associated with heightened aversive responding across disorder-specific and nonspecific aversive stimuli. Clinical and theoretical implications are discussed. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Religious symptoms have been recognized as a presentation of obsessive-compulsive disorder (OCD) for centuries. The two main treatment strategies for OCD, cognitive behavior therapy (exposure and response prevention [ERP]), and SSRIs have been shown to be effective in religious OCD. The presentation of religious OCD within formal prayer, reported in Judaism and Islam, poses special challenges of inaccessibility of personal prayer, sanctity of the symptom, and the status of the therapist. A method of guided-prayer repetition, a variant of ERP, is described, and its successful application is reported in three cases of ultra-orthodox Jewish men with prayer as the main symptom of their religious OCD.

    Although an attentional bias for threat has been implicated in obsessive-compulsive disorder (OCD), evidence supporting such a bias has been inconsistent. Furthermore, few studies have made distinctions between attentional capture vs. attentional disengagement and the extent to which different emotional content modulates attention in OCD also remains unclear. To address these issues, we examined patients with OCD (n = 30) and controls (n = 30) during an emotional attentional blink paradigm in which participants searched for a target embedded within a series of rapidly presented images. Critically, an erotic, fear, disgust, or neutral distracter image appeared 200 ms or 800 ms before the target. Impaired target detection was observed among OCD patients relative to controls following erotic distracters, but only when presented 800 ms, and not 200 ms, prior to the target, indicating difficulty with attentional disengagement. Difficulty disengaging from erotic images was significantly correlated with OCD symptoms in the full sample but not with symptoms of trait anxiety. These data delineate a specific information processing abnormality in OCD. PMID:21801779

    Patients with obsessive-compulsive disorder (OCD) experience abnormally high levels of uncertainty, and unpredictability is evaluated negatively and not well tolerated. The current study examined neural correlates of attentional processing in response to experimentally induced uncertainty in OCD. Twenty-four OCD patients and 24 healthy controls performed a task where neutral and negative pictures were preceded by a cue, either being predictive (certain condition) or nonpredictive (uncertain condition) of subsequent picture valence. We examined prepicture anticipatory attention through α (∼8-12 Hz) suppression, and attentional allocation during picture presentation with the P1, N1, P2, N2, and late positive potential (LPP) of the event-related potential. Additionally, we tested how clinical measures related to these attentional markers. Subjectively, patients overestimated the frequency of negative pictures after nonpredictive cues. Patients, but not controls, showed upper α(10-12 Hz) suppression after nonpredictive and predictive negative cues relative to predictive neutral cues. Only patients showed increased P2 and decreased N2 amplitudes for pictures after nonpredictive cues, and, whereas both groups showed increased LPP amplitudes for pictures after nonpredictive cues, this modulation was more pronounced in OCD during the early LPP (pictures were associated positively with anxiety and negatively with depression. These results suggest that OCD patients process anticipation of inevitable and potential threat similarly and highlight the substantial motivational impact of uncertain events to OCD patients. Finally, the correlation with anxiety implies that anxiety represents the source of hypervigilance during uncertainty resolution. © 2017 Wiley Periodicals, Inc.

    Altered brain activities in the cortico-striato-thalamocortical (CSTC) circuitry are implicated in the pathophysiology of obsessive-compulsive disorder (OCD). However, whether the underlying changes occur only within this circuitry or in large-scale networks is still not thoroughly understood. This study performed voxel-based functional connectivity analysis on resting-state functional magnetic resonance imaging (fMRI) data from thirty OCD patients and thirty healthy controls to investigate whole-brain intrinsic functional connectivity patterns in OCD. Relative to the healthy controls, OCD patients showed decreased functional connectivity within the CSTC circuitry but increased functional connectivity in other brain regions. Furthermore, decreased left caudate nucleus-thalamus connectivity within the CSTC circuitry was positively correlated with the illness duration of OCD. This study provides additional evidence that CSTC circuitry may play an essential role and alteration of large-scale brain networks may be involved in the pathophysiology of OCD.

    Previous neuropsychological studies of obsessive-compulsive disorder (OCD) have indicated impaired executive functioning and nonverbal memory. The extent to which impaired executive functioning impacts nonverbal memory has not been established. The current study investigated the mediating effects of organizational strategies used when copying a figure on subsequent nonverbal memory for that figure. We examined neuropsychological performance in 20 unmedicated subjects with OCD and 20 matched normal control subjects. Subjects were administered the Rey-Osterrieth Complex Figure Test (RCFT) and neuropsychological tests assessing various aspects of executive function. OCD subjects differed significantly from healthy control subjects in the organizational strategies used to copy the RCFT figure, and they recalled significantly less information on both immediate and delayed testing. Multiple regression analyses indicated that group differences in immediate percent recall were significantly mediated by copy organizational strategies. Further exploratory analyses indicated that organizational problems in OCD may be related to difficulties shifting mental and/or spatial set. Immediate nonverbal memory problems in OCD subjects were mediated by impaired organizational strategies used during the initial copy of the RCFT figure. Thus, the primary deficit was one affecting executive function, which then had a secondary effect on immediate memory. These findings are consistent with current theories proposing frontal-striatal system dysfunction in OCD.

    Cognitive-behavioral therapy (CBT), which encompasses exposure with response prevention (ERP) and cognitive therapy (CT), has demonstrated efficacy in the treatment of obsessive-compulsive disorder (OCD). However, the samples studied (reflecting the heterogeneity of OCD), the interventions examined (reflecting the heterogeneity of CBT), and the definitions of treatment response vary considerably across studies. This review examined the meta-analyses conducted on ERP and cognitive therapy (CT) for OCD. Also examined was the available research on long-term outcome associated with ERP and CT. The available research indicates that ERP is the first line evidence based psychotherapeutic treatment for OCD and that concurrent administration of cognitive therapy that targets specific symptom-related difficulties characteristic of OCD may improve tolerance of distress, symptom-related dysfunctional beliefs, adherence to treatment, and reduce drop out. Recommendations are provided for treatment delivery for OCD in general practice and other service delivery settings. The literature suggests that ERP and CT may be delivered in a wide range of clinical settings. Although the data are not extensive, the available research suggests that treatment gains following ERP are durable. Suggestions for future research to refine therapeutic outcome are also considered.

    Objective: To evaluate the therapeutic effect of surgery in obsessive-compulsive disorder (OCD) patients with 18 F-FDG PET imaging. Methods: 18 F-fluorodeoxyglucose (FDG)-PET images were obtained in 9 patients with OCD (6 male and 3 female) before and after 3 to 4 weeks of bilateral capsulotomy, PET images were also performed in 10 controls. Each OCD patient was also evaluated both before and after the surgery by various neuropsychiatric tests including Y-BOCS, HAMA and HAMD. Results: Compare with normal controls, 9 cases of OCD demonstrated high 18 F-FDG uptake in frontal, cingulate, orbital gyri, caudate and thalamus. After capsulotomy, 6 of 9 cases showed better results, the metabolic ratios were also significant decreased in the following areas: anterior cingule gyrus: right (P < 0.001) left (P < 0.05), caudate nuclei: right (P < 0.01) left (P < 0.05), anterolateral orbital frontal cortex: right (P < 0.01) left (P < 0.05), there is no significant changes in bilateral thalamus. Meanwhile, the OCD scales also have significant decreased values in Y-BOCS (P < 0.05) and HARS (P < 0.001). Conclusions: These results indicated that cingule-striatum-pallidum-thalamic circuit is closely related to OCD, and glucose metabolism in these areas decreases significantly after bilateral capsulotomy

    The aim of the current paper is to provide the first comparison of computational mechanisms and neurofunctional substrates in adolescents with attention-deficit/hyperactivity disorder (ADHD) and adolescents with obsessive-compulsive disorder (OCD) during decision making under ambiguity. Sixteen boys with ADHD, 20 boys with OCD, and 20 matched control subjects (12-18 years of age) completed a functional magnetic resonance imaging version of the Iowa Gambling Task. Brain activation was compared between groups using three-way analysis of covariance. Hierarchical Bayesian analysis was used to compare computational modeling parameters between groups. Patient groups shared reduced choice consistency and relied less on reinforcement learning during decision making relative to control subjects, while adolescents with ADHD alone demonstrated increased reward sensitivity. During advantageous choices, both disorders shared underactivation in ventral striatum, while OCD patients showed disorder-specific underactivation in the ventromedial orbitofrontal cortex. During outcome evaluation, shared underactivation to losses in patients relative to control subjects was found in the medial prefrontal cortex and shared underactivation to wins was found in the left putamen/caudate. ADHD boys showed disorder-specific dysfunction in the right putamen/caudate, which was activated more to losses in patients with ADHD but more to wins in control subjects. The findings suggest shared deficits in using learned reward expectancies to guide decision making, as well as shared dysfunction in medio-fronto-striato-limbic brain regions. However, findings of unique dysfunction in the ventromedial orbitofrontal cortex in OCD and in the right putamen in ADHD indicate additional, disorder-specific abnormalities and extend similar findings from inhibitory control tasks in the disorders to the domain of decision making under ambiguity.

    Full Text Available Background: Research on anger attacks has been mostly limited to depression, and only a few studies have focused on anger attacks in obsessive compulsive disorder. Materials and Methods: In a cross-sectional study all new obsessive compulsive disorder patients aged 20-60 years attending an outpatient clinic were assessed using the anger attack questionnaire, irritability, depression and anxiety scale (for the direction of the aggressive behavior and quality of life (QOL. Results: The sample consisted of 42 consecutive subjects with obsessive compulsive disorder, out of which 21 (50% had anger attacks. The obsessive compulsive disorder subjects with and without anger attacks did not show significant differences in terms of sociodemographic variables, duration of illness, treatment, and family history. However, subjects with anger attacks had significantly higher prevalence of panic attacks and comorbid depression. Significantly more subjects with anger attacks exhibited aggressive acts toward spouse, parents, children, and other relatives in the form of yelling and threatening to hurt, trying to hurt, and threatening to leave. However, the two groups did not differ significantly in terms of QOL, except for the psychological domain being worse in the subjects with anger attacks. Conclusion: Anger attacks are present in half of the patients with obsessive compulsive disorder, and they correlate with the presence of comorbid depression.

    Recent acceptance that obsessive-compulsive disorder (OCD) represents a heterogeneous phenomenon has underscored the need for dimensional approaches to this disorder. However little is known about the relation between neuropsychological functions and symptom dimensions. The purpose of this study was to identify the cognitive deficits correlated with specific symptom dimensions. Thirteen categories in the Yale-Brown Obsessive Compulsive Scale symptom checklist from 144 patients with OCD were analyzed by principal component analysis. Correlations between identified symptom dimensions and neuropsychological functioning, measured by the Boston Qualitative Scoring System, were analyzed. Five factors or dimensions were identified: contamination/cleaning, hoarding, symmetry/ordering, obsessions/checking, and repeating/counting. Dysfunctions in nonverbal memory and organizational strategies were related to the symmetry/ordering dimension and the obsessions/checking dimension, respectively. The results of the present study support a transculturally stable symptom structure for OCD. They also suggest the possibility that nonverbal memory dysfunction and organizational impairment are mediated by distinct obsessive-compulsive dimensions. Copyright © 2010 Elsevier Ltd.

    Objective: To assess the changes in regional glucose metabolism following bilateral capsulotomy in patients with medically intractable obsessive-compulsive disorder (OCD). Methods: Eight OCD patients underwent bilateral anterior capsulotomy. 18 F-fluorodeoxyglucose (FDG) PET data obtained before and after operation were subjected to statistical parameter mapping (SPM) . Results: The glucose metabolism decrease was found in the left cingulategyrus, caudatum, left and right thalamic nucleus medialis dorsalis nuclei, bilateral medial and inferior frontal white matter. Conclusion: SPM analysis showed the significant change of cingulate-striatum-thalamic circuits in OCD patients after operation, and the findings implicate that the decreased cerebral metabolism in cingulate gyrus, striatum, and thalamus could be related to bilateral capsulotomy which blocks the abnormal functional connection of corticolimbic loop
