BackgroundDespite knowledge of amygdala involvement in fear and anxiety, its contribution to the pathophysiology of obsessive–compulsive disorder (OCD) remains controversial. In the context of neuroimaging studies, it seems likely that the heterogeneity of the disorder might have contributed to a lack of consistent findings.AimsTo assess the influence of OCD symptom dimensions on amygdala responses to a well-validated emotional face-matching paradigm.MethodCross-sectional functional magnetic resonance imaging (fMRI) study of 67 patients with OCD and 67 age-, gender- and education-level matched healthy controls.ResultsThe severity of aggression/checking and sexual/religious symptom dimensions were significantly associated with heightened amygdala activation in those with OCD when responding to fearful faces, whereas no such correlations were seen for other symptom dimensions.ConclusionsAmygdala functional alterations in OCD appear to be specifically modulated by symptom dimensions whose origins may be more closely linked to putative amygdala-centric processes, such as abnormal fear processing.

Introduction: Obsessive-compulsive disorder has a broadly diverse clinical expression that reflects heterogeneity. Several studies have identified consistent symptom dimensions of obsessivecompulsive disorder. The purpose of this study was to conduct an exploratory symptoms analysis of obsessive-compulsive symptoms in adolescents and adults with obsessive-compulsive disorder. Methods: This was a cross-sectional study conducted in the Department of Psychiatry, National Medical College. This study examined lifetime occurrence of obsessive-compulsive symptoms included in the 13 symptom categories of the Yale–Brown Obsessive Compulsive Scale. Symptoms analysis was performed on 60 patients with obsessive-compulsive disorder. Eight categories of obsessions and six categories of compulsions from Yale–Brown Obsessive Compulsive Scale were included in the analyses. SPSS software package (version 16) was used to analyze the data and shown in the table. Results: Of 60 adolescents and adults, female and male were in the ratio of 1.2:1. Contamination was the most common occurring obsession followed by aggressive obsession. The most common occurring compulsion was checking followed by washing. Only a minority of patients (13.33%) presented predominantly with obsessions however 18.33% patients presented predominantly with compulsions. Certain obsessions and compulsions co-occur to form a cluster. Conclusions: In adolescents and adults, obsessive-compulsive disorder is a multidimensional disorder. Symptom dimensions are predominantly congruent with those described in similar studies of adults with obsessive-compulsive disorder. Keywords: compulsion; obsession; obsessive-compulsive disorder.

AbstractBackgroundObsessive–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.AimTo 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.MethodsCross-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.ResultsThere 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.ConclusionsSuicidality 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.

Background: Obsessive–compulsive disorder (OCD) is a very heterogeneous condition that frequently includes symptoms of the “symmetry dimension” (i.e., obsessions and/or compulsions of symmetry, ordering, repetition, and counting), along with aggressive, sexual/religious, contamination/cleaning, and hoarding dimensions. Methods: This cross-sectional study aimed to investigate the prevalence, severity, and demographic and clinical correlates of the symmetry dimension among 1001 outpatients from the Brazilian Research Consortium on Obsessive–Compulsive Spectrum Disorders. The main assessment instruments used were the Dimensional Yale–Brown Obsessive–Compulsive Scale, the Yale–Brown Obsessive–Compulsive Scale, the USP-Sensory Phenomena Scale, the Beck Depression and Anxiety Inventories, the Brown Assessment of Beliefs Scale, and the Structured Clinical Interview for DSM-IV Axis I Disorders. Chi-square tests, Fisher’s exact tests, Student’s t-tests, and Mann–Whitney tests were used in the bivariate analyses to compare patients with and without symptoms of the symmetry dimension. Odds ratios (ORs) with confidence intervals and Cohen’s D were also calculated as effect size measures. Finally, a logistic regression was performed to control for confounders. Results: The symmetry dimension was highly prevalent (86.8%) in this large clinical sample and, in the logistic regression, it remained associated with earlier onset of obsessive–compulsive symptoms, insidious onset of compulsions, more severe depressive symptoms, and presence of sensory phenomena. Conclusions: A deeper knowledge about specific OCD dimensions is essential for a better understanding and management of this complex and multifaceted disorder.

BackgroundExisting neuropsychological studies of obsessive–compulsive disorder (OCD) are cross-sectional and do not provide evidence of whether deficits are trait-related (antecedent and independent of symptomatology) or state-related (a consequence, dependent on symptomatology).AimsTo investigate whether there are premorbid neuropsychological deficits associated with adult OCD.MethodLongitudinal data were collected from participants of the Dunedin Multidisciplinary Health and Developmental study. Neuropsychological data collected at age 13 were linked with age 32 diagnosis of OCD.ResultsThe group who had OCD at age 32 differed significantly from the control group with no OCD on their performance at age 13 on neuropsychological tests of visuospatial, visuoconstructive and visuomotor skills, controlling for gender and socioeconomic status, but did not differ on tests of general IQ or verbal ability. Performance of the group with OCD on tests of executive functioning was mixed.ConclusionsIndividuals with OCD have premorbid impairment in visuospatial abilities and some forms of executive functioning, consistent with biological models of OCD.

Treatment Refractory

Object Recent findings have suggested a correlation between obsessive-compulsive disorder (OCD) symptom dimensions and clinical outcome after limbic system surgery for treatment-refractory patients. Based on previous evidence that the hoarding dimension is associated with worse outcome in conventional treatments, and may have a neural substrate distinct from OCD, the authors examined a large sample of patients undergoing limbic surgery (40 with capsulotomy, 37 with cingulotomy) and investigated if symptom dimensions, in particular hoarding, could influence treatment outcome. Methods Data from 77 patients from 3 different research centers at São Paulo (n = 17), Boston (n = 37), and Stockholm (n = 23) were analyzed. Dimensional Yale-Brown Obsessive Compulsive Scale (Y-BOCS; São Paulo) or Y-BOCS Symptom Checklist scores (Boston and Stockholm) were used to code the presence of 4 well-established symptom dimensions: forbidden thoughts, contamination/cleaning, symmetry/order, and hoarding. Reductions in YBOCS scores determined clinical outcome. Results Mean Y-BOCS scores decreased 34.2% after surgery (95% CI 27.2%–41.3%), with a mean follow-up of 68.1 months. Patients with hoarding symptoms had a worse response to treatment (mean Y-BOCS decrease of 22.7% ± 25.9% vs 41.6% ± 32.2%, respectively; p = 0.006), with no significant effect of surgical modality (capsulotomy vs cingulotomy). Patients with forbidden thoughts apparently also had a worse response to treatment, but this effect was dependent upon the co-occurrence of the hoarding dimension. Only the negative influence of the hoarding dimension remained when an ANOVA model was performed, which also controlled for preoperative symptom severity. Conclusions The presence of hoarding symptoms prior to surgery was associated with worse clinical outcome after the interventions. Patients with OCD under consideration for ablative surgery should be carefully screened for hoarding symptoms or comorbid hoarding disorder. For these patients, the potentially reduced benefits of surgery need to be carefully considered against potential risks.
