Clinical characteristics of probands with obsessive-compulsive disorder from simplex and multiplex families. Psychiatry Res 2024; 331:115627.

Abstract
Genetic and non-genetic factors contribute to obsessive-compulsive disorder (OCD), with strong evidence of familial clustering. Genomic studies in psychiatry have used the concepts of families that are "simplex" (one affected) versus "multiplex" (multiple affected). Our study compares demographic and clinical data from OCD probands in simplex and multiplex families to uncover potential differences. We analyzed 994 OCD probands (501 multiplex, 493 simplex) from the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders (C-TOC). Clinicians administered the Structured Clinical Interview for DSM-IV (SCID-IV) to diagnose, Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess severity, and Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS) to assess symptom dimensionality. Demographics, clinical history, and family data were collected. Compared to simplex probands, multiplex probands had earlier onset, higher sexual/religious and hoarding dimensions severity, increased comorbidity with other obsessive-compulsive-related disorders (OCRD), and higher family history of psychiatric disorders. These comparisons provide the first insights into demographic and clinical differences between Latin American simplex and multiplex families with OCD. Distinct clinical patterns may suggest diverse genetic and environmental influences. Further research is needed to clarify these differences, which have implications for symptom monitoring and management.

[PMID: 37793476 DOI: 10.1016/j.jad.2023.09.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 09/20/2023] [Accepted: 09/30/2023] [Indexed: 10/06/2023]
Abstract
BACKGROUND Dysmorphic concern (DC) is a symptom affecting both clinical and non-clinical populations, with a severe impact on individuals' physical and psychological well-being. While Childhood Trauma (CT) has been identified as a risk factor for DC, there is a lack of research on a specific form of CT, that is, parental overcontrol. Therefore, the current study aimed to investigate the association between DC and parental overcontrol in a community sample of adults, controlling for other forms of CT and potential confounding variables. METHOD 714 adults (508 females; mean age: 30.29 ± 11.67 years; age range: 18-77) participated in an online survey including the Body Image Concern Inventory (BICI), the Overcontrol subscale of the Measure Of Parental Style, and the Childhood Trauma Questionnaire - Short Form (CTQ-SF). RESULTS Parental overcontrol was independently associated with DC symptoms (β = 0.111; p = .005; CI = [0.119;0.666]), even after controlling for other forms of CT and sociodemographic and clinical confounding variables. LIMITATIONS The cross-sectional design of the study, the unbalanced sex ratio, the retrospective self-reported data about parental overcontrol and CT should be considered. CONCLUSIONS This finding suggests that parental overcontrol may play a role in the development and maintenance of DC symptoms, remarking the urge to take more into account parental overcontrol in the assessment of CT.

Abstract
OBJECTIVE To assess executive functions (EFs) in patients with body dysmorphic disorder (BDD) and obsessive-compulsive disorder (OCD) compared with healthy controls. METHODS Adults diagnosed with BDD (n = 26) or OCD (n = 29) according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and healthy controls (n = 28) underwent validated and computerized neuropsychological tests, spatial working memory (SWM), intra-extra-dimensional set shifting (IED), and stop signal task (SST), from the Cambridge Neuropsychological Test Automated Battery (CANTAB). Test performance was compared between groups, and correlated with standardized symptom severity of BDD and OCD. Significance level was set to P < .05. RESULTS There were no statistically significant between-group differences on key outcome measures in SWM, IED, or SST. There was a weak positive correlation between symptom severity and test errors on SWM and IED in both OCD and BDD groups; increased clinical severity was associated with more errors in these tests. Furthermore, there was a negative correlation between symptom severity and SST in the BDD group. CONCLUSIONS Patients with BDD or OCD did not differ from healthy control subjects in terms of test performance; however, there were several statistically significant correlations between symptom severity and performance in those with BDD or OCD. More studies on EFs in BDD and OCD are required to elucidate if there are differences in EFs between these two disorders.

Abstract
OBJECTIVE Aim: To find out the prevalence of body dysmorphic disorder among patients seeking facial cosmetic procedures, find out association of social demographic (age, gender, occupation, marital status, friends relationship, and dating status) ampatientsient with body dysmorphic disorder. PATIENTS AND METHODS Materials and Methods: A cross-sectional study was done on a sample of 100 patients from Al-waste Hospital and Ghazy Al-Hariri Hospital for surgical specialties in Baghdad by using a body dysmorphic disorder questionnaire to diagnose a probable case and then a semi-structured questionnaire based on DSM5 criteria to diagnose body dysmorphic disorder during the period extended from beginning of January 2019 to the end of April 2019. RESULTS Results: The chi-square test proved the association between female gender and body dysmorphic disorder is significant P=0.026. Significant associations were also noticed between single patients and body dysmorphic disorder 76.8% in comparison with married 37.8, and divorced or widowed 42.9% (P=0.001). It was found that 68.6% of unemployed patients think that they need to correct their body dysmorphic disorder so they attended the hospital while only 40% of employed persons did so P=0.008. The mean age of patients exposed to a second operation was significantly higher than the mean age of other patients P=0.022. CONCLUSION Conclusions: High prevalence of body dysmorphic disorder among patients seeking plastic surgery which is about 60%. Body dysmorphic disorder is more common among single and unemployment and among young adults and gender female. There is no significant association between the mean age of male and female patients of body dysmorphic disorder group.

Abstract
(1) Background: Even though the comorbidity of obsessive-compulsive disorder (OCD) and a psychotic disorder (PD), such as schizophrenia, is being increasingly recognized, the impact of this comorbidity on the clinical presentation, including insight into obsessive-compulsive symptoms and the functioning of OCD, remains unclear. (2) Methods: To investigate clinical differences between OCD patients with and without PD, 86 Japanese outpatients who met the DSM-IV-TR criteria for OCD were recruited and divided into two groups: 28 OCD patients with PD, and 58 OCD patients without PD. The two groups were cross-sectionally compared in terms of their sociodemographic profiles and clinical characteristics, including the DSM-IV-TR insight specifier and the Global Assessment of Functioning (GAF). (3) Results: The results showed that OCD patients with PD scored lower on both the insight and GAF assessments. (4) Conclusions: The present study suggests that comorbid PD in OCD is a clinical entity.

Abstract
This study explored the expression, occurrence, and treatment outcomes of comorbid body dysmorphic disorder (BDD) in 107 youth (7-17 years) seeking treatment for primary obsessive-compulsive disorder (OCD). In the overall sample, appearance anxiety (AA) was positively associated with OCD-related impairment, severity, symptom frequency, comorbid symptoms, and maladaptive emotion regulation. Comorbid BDD occurred in 9.35% of youth, equally affected males and females, and was associated with older age. AA negligibly reduced following treatment. Compared to those without (a) comorbid BDD and (b) without any comorbidity, youth with comorbid BDD reported greater social impairment and reduced global functioning but did not differ on the occurrence of comorbid anxiety and mood disorders. OCD response or remission rates did not differ. In youth with comorbid BDD, AA did not significantly reduce following treatment. Results suggest a more severe expression accompanies comorbid BDD in youth with OCD, with BDD persisting following OCD treatment.

Abstract
This review covers recent findings in the genomics of obsessive-compulsive disorder (OCD), obsessive-compulsive symptoms, and related traits from a dimensional perspective. We focus on discoveries stemming from technical and methodological advances of the past five years and present a synthesis of human genomics research on OCD. On balance, reviewed studies demonstrate that OCD is a dimensional trait with a highly polygenic architecture and genetic correlations to multiple, often comorbid psychiatric phenotypes. We discuss the phenotypic and genetic findings of these studies in the context of the dimensional framework, relying on a continuous phenotype definition, and contrast these observations with discoveries based on a categorical diagnostic framework, relying on a dichotomous case/control definition. Finally, we highlight gaps in knowledge and new directions for OCD genetics research.

Abstract
OBJECTIVES Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder, often complicated with comorbidities. Social phobia (SP) is the most frequent co-occurring anxiety disorder in OCD, associated with increased clinical severity. However, no study had examined the relevance of interpersonal processes in this comorbidity, which are at the core of SP. This study characterized the clinical (i.e., symptom profile, age of onset, chronicity, and comorbidity), vulnerability (i.e., childhood trauma, negative life events), and interpersonal (attachment style, expressed emotion, and social support) correlates of comorbid SP in a large sample of OCD patients. METHODS We analysed the data of 382 OCD patients participating in the Netherlands Obsessive Compulsive Disorder Association (NOCDA) study. We examined the correlates of SP in OCD using self-report questionnaires and structured clinical interviews. In addition, data of 312 non-OCD SP patients were drawn from the Netherlands Study of Depression and Anxiety (NESDA), to compare the age of onset of SP between groups. Descriptive univariate analyses were followed by backward stepwise logistic regression analyses. RESULTS Social phobia was present among approximately 20% of OCD patients. Social phobia in OCD was associated with increased depression severity and decreased ratings of secure attachment style. Among OCD patients, SP had a significantly earlier age onset as compared to SP in non-OCD patients. CONCLUSION Social phobia in OCD might render a vulnerable clinical picture, characterized with early onset of SP symptoms, insecure attachment style, and increased depressive symptoms. Future studies should use prospective designs to better understand the nature of comorbid SP in OCD. PRACTITIONER POINTS Approximately one fifth of OCD patients were diagnosed with comorbid social phobia in a large representative clinical sample. OCD patients with comorbid social phobia presented with a vulnerable clinical picture, characterized with increased depression severity and decreased ratings of secure attachment style. Social phobia in OCD was associated with an earlier AOO as compared to the AOO of social phobia without OCD. The findings are limited by a cross-sectional design; thus, causality could not be assessed. Research is needed to further examine the mechanisms of comorbid social phobia in OCD.

Abstract
We report the case of an adolescent with hypohidrotic ectodermal dysplasia, who had obsessive-compulsive disorder and was later diagnosed with body dysmorphic disorder (BDD). BDD is a highly distressing, adolescent-onset disorder that may lead to social isolation, the development of comorbid mental health disorders and suicidality. Patients typically lack insight into their BDD and frequently present to dermatologists for medical treatment. In this paper, we address the challenges faced when working with patients with BDD.

Abstract
Obsessive-compulsive disorder (OCD) is a chronic psychiatric disorder that is characterized by obsessions and compulsions. Obsessions are uncontrollable distressful thoughts. Compulsions are recurrent behaviors or thoughts performed in an attempt to decrease the anxiety of the obsessions. Body dysmorphic disorder (BDD) is a mental disorder characterized by a distressful preoccupation with a perceived defect in appearance. The perceived flaw in appearance is minimal or unnoticed by others. BDD was considered an anxiety disorder in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV). In the DSM-V, it was added to the obsessive-compulsive and related disorders category. The objective of this literature review was to explore the psychiatric comorbidities and the risk of suicide associated with OCD and BDD. Our study results showed OCD and BDD share common genetic and environmental risk factors, clinical features, and sociodemographic profiles. Both OCD and BDD are related disorders that commonly coexist. The suicide risk in OCD is increased as the intensity of the obsessions, trait perfectionism, and alexithymia increases. The suicide risk in BDD is increased by the presence of other disorders such as substance use disorder, major depressive disorder, eating and personality disorders. People with comorbid OCD-BDD have high morbidity, a decrease in insight and poor psychosocial functions. They have higher rates of anxiety, schizotypal features, and suicidal ideation compared to those with BDD or OCD alone.

Abstract
Body dysmorphic disorder (BDD), together with its subtype muscle dysmorphia (MD), has been relocated from the Somatoform Disorders category in the DSM-IV to the newly created Obsessive-Compulsive and Related Disorders category in the DSM-5. Both categorizations have been criticized, and an empirically derived classification of BDD is lacking. A community sample of N = 736 participants completed an online survey assessing different psychopathologies. Using a structural equation modeling approach, six theoretically derived models, which differed in their allocation of BDD symptoms to various factors (i.e. general psychopathology, somatoform, obsessive-compulsive and related disorders, affective, body image, and BDD model) were tested in the full sample and in a restricted sample (n = 465) which indicated primary concerns other than shape and weight. Furthermore, measurement invariance across gender was examined. Of the six models, only the body image model showed a good fit (CFI = 0.972, RMSEA = 0.049, SRMR = 0.027, TLI = 0.959), and yielded better AIC and BIC indices than the competing models. Analyses in the restricted sample replicated these findings. Analyses of measurement invariance of the body image model showed partial metric invariance across gender. The findings suggest that a body image model provides the best fit for the classification of BDD and MD. This is in line with previous studies showing strong similarities between eating disorders and BDD, including MD. Measurement invariance across gender indicates a comparable presentation and comorbid structure of BDD in males and females, which also corresponds to the equal prevalence rates of BDD across gender.

Abstract
Background and Objectives:
Body Dysmorphic Disorder (BDD) is characterized
by an abnormal preoccupation with alleged misshapen body parts. There is often poor insight
and effort is made to hide the imagined defects, and consultation may be sought seeking
unnecessary cosmetic surgery or procedures. It is underdiagnosed and established treatment
protocols are lacking. The disease has a chronic and undulating course and is seriously
compromises quality of life. Despite the fact that the prime age of onset of BDD is during
adolescence relatively little has been written about it during this phase of life. This review
aims to comprehensively cover the present understanding of BDD, including clinical
features, epidemiology, psychopathology, nomenclature, comorbidity and management.
Methods:
A literature search was undertaken using suitable key words on Google Scholar,
MEDLINE & PsychoINFO up to June 2018 limited to articles in English.
Results:
he prevalence of BDD is variable in the general and psychiatric population with
equal gender distribution. Both sexes are equally affected. It is associated with poor
functioning and a chronic course. There is considerable comorbidity and diagnostic overlap
between BDD and obsessive-compulsive disorder, major depressive disorder, social anxiety
disorder, anorexia nervosa, schizophrenia spectrum disorders and personality disorders.
Psychiatric consultation is often late. Selective Serotonin Reuptake Inhibitors (SSRIs) and
Cognitive Behavior Therapy (CBT) are currently the first line modalities for treatment.
Internet based CBT, Acceptance and commitment therapy, and repetitive Transcranial
Magnetic Stimulation (rTMS) are emerging treatment options.
Conclusions:
BDD is a complex disorder with still lot of uncertainty about its diagnostic
placement, treatment approaches, especially for refractory patients, and prognosis. Further
study is needed to clarify its prevalence, especially in adolescents; to fully understand its
neurobiological aspects, to determine its exact relation to obsessive compulsive related
disorders, and to develop better treatment approaches.

Abstract
OBJECTIVE Current nosology conceptualises body dysmorphic disorder as being related to obsessive-compulsive disorder, but the direct evidence to support this conceptualisation is mixed. In this systematic review, we aimed to provide an integrated overview of research that has directly compared body dysmorphic disorder and obsessive-compulsive disorder. METHOD The PubMed database was searched for empirical studies which had directly compared body dysmorphic disorder and obsessive-compulsive disorder groups across any subject matter. Of 379 records, 31 met inclusion criteria and were reviewed. RESULTS Evidence of similarities between body dysmorphic disorder and obsessive-compulsive disorder was identified for broad illness features, including age of onset, illness course, symptom severity and level of functional impairment, as well as high perfectionism and high fear of negative evaluation. However, insight was clearly worse in body dysmorphic disorder than obsessive-compulsive disorder, and preliminary data also suggested unique visual processing features, impaired facial affect recognition, increased social anxiety severity and overall greater social-affective dysregulation in body dysmorphic disorder relative to obsessive-compulsive disorder. CONCLUSION Limitations included a restricted number of studies overall, an absence of studies comparing biological parameters (e.g. neuroimaging), and the frequent inclusion of participants with comorbid body dysmorphic disorder and obsessive-compulsive disorder. Risks of interpreting common features as indications of shared underlying mechanisms are explored, and evidence of differences between the disorders are placed in the context of broader research findings. Overall, this review suggests that the current nosological status of body dysmorphic disorder is somewhat tenuous and requires further investigation, with particular focus on dimensional, biological and aetiological elements.

Abstract
Currently, all second-generation antipsychotics are approved for schizophrenia. Many are also approved for bipolar disorder, with some also approved as adjunctive treatment for depression and autism-related irritability. Second-generation antipsychotics are increasingly being prescribed for indications other than those approved by the Food and Drug Administration, such as in dementia, anxiety, and post-traumatic stress disorder to name a few. Obsessive-compulsive and related disorders are a group of disorders characterized by preoccupation and repetitive behaviors. According to the latest edition of the Diagnostic and Statistical Manual of Mental Disorders, obsessive-compulsive disorder, body dysmorphic disorder, trichotillomania, hoarding disorder, and excoriation, the latter two being newly designated disorders, fall under obsessive-compulsive and related disorders. Due to a lack of well designed clinical studies specifically addressing the use of second-generation antipsychotics in obsessive-compulsive and related disorders, it is unknown whether these agents are clinically beneficial. Current research describing the pathophysiology of these disorders shows the involvement of similar brain regions and neurotransmitters across the five obsessive-compulsive and related disorders. Despite differences in the receptor binding profiles, second-generation antipsychotics share many common pharmacodynamics properties. This review sought to examine all the published reports of second-generation antipsychotics being used in the management of symptoms of the aforementioned diseases and compile evidence for clinicians who encounter patients who are unresponsive to standard treatment.

Abstract
Body dysmorphic disorder is a challenging disorder that manifests as erroneously perceived flaws in one’s physical appearance and repetitive behaviors in response to appearance concerns. This disorder is also frequently comorbid with other psychiatric disorders, including major depressive disorder and autism spectrum disorder. It is currently understood to arise from a combination of biological, psychological, and environmental factors. Treatment of body dysmorphic disorder typically consists of a combination of pharmacotherapy and cognitive behavioral therapy. However, not all patients respond to treatment, and BDD symptoms remain even in those who do respond. This review outlines current pharmacological and neuromodulation treatments for body dysmorphic disorder and suggests directions for future studies of novel treatments such as augmentation with atypical antipsychotics and the use of intranasal oxytocin in cases of body dysmorphic disorder that show residual symptomatology even with tailored monotherapy. There is emerging evidence suggesting that non-invasive neurostimulatory techniques, such as repetitive transcranial magnetic stimulation, may be of value in treatment-resistant cases.

Abstract
BACKGROUND Body dysmorphic disorder (BDD) was categorised in DSM-5 within the newly created 'obsessive-compulsive and related disorders' chapter, however this classification remains subject to debate. Confirmatory factor analysis was used to test competing models of the co-occurrence of symptoms of BDD, obsessive-compulsive disorder, unipolar depression, anxiety, and eating disorders in a community sample of adolescents, and to explore potential sex differences in these models. METHODS Self-report questionnaires assessing disorder symptoms were completed by 3149 Australian adolescents. The fit of correlated factor models was calculated separately in males and females, and measurement invariance testing compared parameters of the best-fitting model between males and females. RESULTS All theoretical models of the classification of BDD had poor fit to the data. Good fit was found for a novel model where BDD symptoms formed a distinct latent factor, correlated with affective disorder and eating disorder latent factors. Metric non-invariance was found between males and females, and the majority of factor loadings differed between males and females. Correlations between some latent factors also differed by sex. LIMITATIONS Only cross-sectional data were collected, and the study did not assess a broad range of DSM-5 defined eating disorder symptoms or other disorders in the DSM-5 obsessive-compulsive and related disorders chapter. CONCLUSIONS This study is the first to statistically evaluate competing models of BDD classification. The findings highlight the unique features of BDD and its associations with affective and eating disorders. Future studies examining the classification of BDD should consider developmental and sex differences in their models.

Abstract
INTRODUCTION In DSM-5, body dysmorphic disorder (BDD) was reclassified under the obsessive-compulsive and related disorders (OCRDs), but little is known about the nature of BDD beliefs. This study aimed to compare level of insight in BDD and consider related implications for DSM-5 classification. METHOD Participants were 27 BDD, 19 obsessive-compulsive disorder (OCD), and 20 psychosis (SZ) participants as well as 42 non-clinical controls (NC), who completed the Brown Assessment of Beliefs Scale (BABS) and Peters Delusions Inventory (PDI). RESULTS For total (and most individual) BABS items, BDD and SZ participants scored significantly higher than OCD and NC participants. On the PDI, there were significant group differences in number of questions endorsed, with clinical groups scoring significantly higher than the NC group on dimensions of distress and preoccupation, but not conviction. CONCLUSION These findings suggest appearance-related concerns in BDD somewhat resemble delusions seen in psychosis (and not OCD), and convey important nosological and therapeutic implications.

Abstract
The aim of this article is to raise awareness of the underdiagnosis of body dysmorphic disorder (BDD) in clinical practice and provide suggestions to overcome key barriers to BDD detection. Disclosure of BDD symptoms is uncommon during routine assessments but can be increased by asking specifically about such symptoms. When BDD symptoms are present, it is important to differentiate them from anxiety, depression, obsessive-compulsive disorder, and eating disorders, which may present with some similarities and are commonly comorbid with BDD. Assessment of BDD should be sensitive to issues of poor insight, elevated suicide risk, subthreshold BDD presentations, and the possibility of BDD by proxy. Furthermore, assessment should consider the potential impact of age, gender, ethnicity, and minor physical defects on the presentation of BDD. Improving the assessment of BDD in routine clinical practice will enhance disclosure, improve case conceptualization, and provide the opportunity to deliver appropriate treatment for this underdiagnosed and often serious disorder.
