[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
Several studies have shown that obsessive-compulsive disorder (OCD), eating disorders (ED), autism spectrum disorders (ASD) and body dysmorphic disorder (BDD) share obsessive-compulsive (OC) symptoms and often co-occur, which could be seen as indicative of a common etiological basis. In addition, they also appear to have similarities in executive functioning. The present study investigated disorder-specific symptoms and executive functioning as a possible joint factor in individuals with OCD (n=53), BDD (n=95), ED (n=171) and ASD (n=73), and in healthy controls (n=110). The participants completed online questionnaires measuring OCD, ED, ASD and BDD related symptoms as well as executive functioning. The clinical groups were first compared to the healthy controls. Subsequently, a network analysis was performed only with the OC-groups. This network approach assumes that psychopathological disorders are the result of causal symptom interactions. As expected, the healthy controls reported less severe symptoms compared to the OC patient groups. The network analysis suggested that the executive functioning skill set shifting/attention switching and the ASD symptoms, social and communication skills were the most central nodes in the model. Difficulty with cognitive flexibility and social factors are central in OC-spectrum disorders and may be perpetuating factors and thus a relevant focus of treatment.

Abstract
Skin-centered body dysmorphic disorder (BDD) and excoriation disorder (ED) are categorized under Obsessive Compulsive and Related Disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and are characterized by excessive or inappropriate skin picking. Patients with skin-centered BDD and ED often first present to dermatology. These conditions are important to recognize and appropriately diagnose, as perpetuation of the disorder is inevitable without appropriate psychiatric treatment. These conditions are associated with increased morbidity and BDD is associated with increased suicide risk. This review aims to present a combined dermatologic and psychiatric approach to diagnosing, differentiating, and managing skin-centered BDD and ED. Patient presentation, DSM-5 criteria, and management approaches are reviewed.

Abstract
Eating disorders are one of the most common causes of pediatric hospitalizations due to primary mental health diagnoses. The purpose of this article is to discuss the challenges clinical psychologists face in working with patients with eating disorders and their families during medical admissions. Using the Psychiatry Consultation Service at a tertiary pediatric academic medical center in the Northeast as a framework, authors present the responsibilities of clinical psychologists on this service and their role within the larger, interdisciplinary team. Topics addressed also include systemic challenges, medical and psychiatric comorbidities, and differential psychiatric diagnoses. Case examples are provided to highlight various challenges as well as potential solutions and approaches. Clinical implications, limitations, and directions for future research are also discussed.

Abstract
People with a body dysmorphic disorder (BDD) suffer from excessive preoccupation and anxiety about an imagined or to others a negligible defect in their appearance. They cannot bear to look at themselves, feel ugly, are convinced that their nose, their physique and their skin are disfiguring. The more concerned they become about their appearance, the more their attention is drawn to the ostensible blemishes and reinforces the impression of their own unattractiveness. Those affected do not consider themselves to be ill, but are convinced that it is a real physical defect which forces them again and again to stand in front of the mirror. Such patients may consult a dermatologist, some even a plastic surgeon, in order to get closer to their ideal of beauty, which perforce remains unattainable for patients because of a distorted perception of their body.

Abstract
Body dysmorphic disorder (BDD), also known as dysmorphophobia, is a condition that consists of a distressing or impairing preoccupation with imagined or slight defects in appearance, associated repetitive behaviors and where insight regarding the appearance beliefs is often poor. Despite the fact it is relatively common, occurs around the world and can have a significant impact on a sufferer's functioning, levels of distress, and risk of suicide, the diagnosis is often missed. In this review, we outline the clinical features of BDD including as characterized in the newly published World Health Organization's International Classification of Diseases 11, review the prevalence of BDD within different settings, and highlight the reasons why BDD may be underdiagnosed even within psychiatric settings. We additionally review the cultural considerations for BDD and finally discuss the evidence-based treatment approaches for BDD, particularly the use of serotonin reuptake inhibitor medication and cognitive behavioral therapy.

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
This study tested the potential transdiagnostic nature of body dysmorphic disorder (BDD), obsessive-compulsive disorder (OCD), and social anxiety disorder (SAD) beliefs, in addition to testing the specificity of those beliefs, in predicting how individuals responded to symptom-specific stressors. Participants included 127 adults (75% women) with a broad range of symptom severity. Path analysis was used to evaluate whether specific maladaptive beliefs predicted distress in response to symptom-relevant stressors over and above other beliefs and baseline distress. SAD beliefs emerged as a significant predictor of distress in response to a mirror gazing (BDD-relevant), a thought (OCD-relevant), and a public speaking (SAD-relevant) task, controlling for other disorder beliefs and baseline distress. BDD beliefs were also a robust predictor of BDD stressor responding. Results suggest that social anxiety-relevant beliefs may function as a transdiagnostic risk factor that predicts in vivo symptoms across a range of problem areas.

Abstract
BACKGROUND Anorexia nervosa (AN) and body dysmorphic disorder (BDD) frequently co-occur, and have several overlapping phenomenological features. Little is known about their shared neurobiology. The aim of the study was to compare modular organization of brain structural connectivity. METHOD We acquired diffusion-weighted magnetic resonance imaging data on unmedicated individuals with BDD (n = 29), weight-restored AN (n = 24) and healthy controls (HC) (n = 31). We constructed connectivity matrices using whole-brain white matter tractography, and compared modular structures across groups. RESULTS AN showed abnormal modularity involving frontal, basal ganglia and posterior cingulate nodes. There was a trend in BDD for similar abnormalities, but no significant differences compared with AN. In AN, poor insight correlated with longer path length in right caudal anterior cingulate and right posterior cingulate. CONCLUSIONS Abnormal network organization patterns in AN, partially shared with BDD, may have implications for understanding integration between reward and habit/ritual formation, as well as conflict monitoring/error detection.

Abstract
BACKGROUND Body dysmorphic disorder (BDD) and anorexia nervosa (AN) are both characterized by distorted perception of appearance. Previous studies in BDD suggest abnormalities in visual processing of own and others' faces, but no study has examined visual processing of faces in AN, nor directly compared the two disorders in this respect. METHOD We collected functional magnetic resonance imaging data on 60 individuals of equivalent age and gender in each of three groups--20 BDD, 20 weight-restored AN, and 20 healthy controls (HC)--while they viewed images of others' faces that contained only high or low spatial frequency information (HSF or LSF). We tested hypotheses about functional connectivity within specialized sub-networks for HSF and LSF visual processing, using psychophysiological interaction analyses. RESULTS The BDD group demonstrated increased functional connectivity compared to HC between left anterior occipital face area and right fusiform face area (FFA) for LSF faces, which was associated with symptom severity. Both BDD and AN groups had increased connectivity compared to HC between FFA and precuneous/posterior cingulate gyrus for LSF faces, and decreased connectivity between FFA and insula. In addition, we found that LSF connectivity between FFA and posterior cingulate gyrus was significantly associated with thoughts about own appearance in AN. CONCLUSIONS Results suggest similar abnormal functional connectivity within higher-order systems for face processing in BDD and AN, but distinct abnormal connectivity patterns within occipito-temporal visual networks. Findings may have implications for understanding relationships between these disorders, and the pathophysiology underlying perceptual distortions.

Abstract
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.

Abstract
Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are psychiatric disorders that involve distortion of the experience of one's physical appearance. In AN, individuals believe that they are overweight, perceive their body as "fat," and are preoccupied with maintaining a low body weight. In BDD, individuals are preoccupied with misperceived defects in physical appearance, most often of the face. Distorted visual perception may contribute to these cardinal symptoms, and may be a common underlying phenotype. This review surveys the current literature on visual processing in AN and BDD, addressing lower- to higher-order stages of visual information processing and perception. We focus on peer-reviewed studies of AN and BDD that address ophthalmologic abnormalities, basic neural processing of visual input, integration of visual input with other systems, neuropsychological tests of visual processing, and representations of whole percepts (such as images of faces, bodies, and other objects). The literature suggests a pattern in both groups of over-attention to detail, reduced processing of global features, and a tendency to focus on symptom-specific details in their own images (body parts in AN, facial features in BDD), with cognitive strategy at least partially mediating the abnormalities. Visuospatial abnormalities were also evident when viewing images of others and for non-appearance related stimuli. Unfortunately no study has directly compared AN and BDD, and most studies were not designed to disentangle disease-related emotional responses from lower-order visual processing. We make recommendations for future studies to improve the understanding of visual processing abnormalities in AN and BDD.

Abstract
Symmetry obsessions are a common symptom of obsessive-compulsive disorder (OCD) and have several demographic and clinical correlates. Appearance-related symmetry concerns appear common in body dysmorphic disorder (BDD); however, no published studies have examined this topic. This study examined the clinical features, prevalence, and correlates of symmetry concerns involving physical appearance in two BDD samples (N=160 and N=115). More than 25% of participants in each sample reported symmetry concerns for a body part with which they were preoccupied (total of 18 body parts in sample 1 and 18 in sample 2). In sample 1, BDD participants with appearance-related symmetry concerns were older than those without appearance-related symmetry concerns. In sample 2, those with appearance-related symmetry concerns reported poorer mental health-related quality of life, were more likely to have experienced lifetime suicidal ideation, had better BDD-related insight, and were less likely to have a lifetime eating disorder. In both samples, participants with appearance-related symmetry concerns were more likely to have lifetime OCD but not OCD-related symmetry obsessions. Thus, symmetry is a common appearance concern in BDD that is associated with comorbid OCD but not with OCD symmetry concerns specifically, suggesting that symmetry concerns may have a different mechanism/pathophysiology in BDD versus OCD.

Abstract
Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are severe body image disorders that highly impair individuals in their daily functioning. They are discrete but overlapping nosological entities. In this review, we examine similarities between AN and BDD with regard to clinical, personality and demographic aspects, such as comorbidity, phenomenology, and treatment outcome. The review suggests that the two disorders are highly comorbid, and show similar ages of onset, illness trajectories, and comparable clinical and personality characteristics. However, important differences emerge in their responsiveness to psychosocial and psychopharmacological treatment, which are discussed. Clinical implications of these findings are summarized and directions for future research are delineated, with a focus on how current treatment components from each disorder may inform new interventions for both disorders.

Abstract
Body dysmorphic disorder (BDD) shares many characteristics with social phobia (SP), including high levels of social anxiety and avoidance, but to our knowledge no studies have directly compared these disorders' demographic and clinical features. Demographic and clinical features were compared in individuals with BDD (n=172), SP (n=644), and comorbid BDD/SP (n=125). SP participants had a significantly earlier age of onset and lower educational attainment than BDD participants. BDD participants were significantly less likely to ever be married than SP participants, had a greater likelihood of ever being psychiatrically hospitalized, and had significantly lower mean GAF scores than SP participants. The two groups had different comorbidity patterns, which included a greater likelihood for BDD participants to have comorbid obsessive-compulsive disorder (OCD) or an eating disorder, vs. a greater likelihood for SP participants to have a comorbid non-OCD anxiety disorder. The comorbid BDD/SP group had significantly greater morbidity across several domains than the SP only group, but not the BDD only group. In summary, although BDD and SP were similar across many demographic and clinical features, they had important differences. Future studies are needed to confirm these findings and address similarities and differences between these disorders across a broader range of variables.

Abstract
OBJECTIVE Research on the prevalence of body dysmorphic disorder (BDD) in individuals with eating disorders (EDs) is scarce. Nonweight-related appearance concerns, which can be considered as variants of BDD concerns, have also rarely been examined in EDs. This study therefore investigates BDD prevalence and nonweight-related appearance concerns in EDs. METHOD One hundred individuals with EDs (49 inpatients with anorexia nervosa, 51 inpatients with bulimia nervosa) completed structured diagnostic interviews and self-report questionnaires. RESULTS Twelve individuals with EDs (12.0%) suffered from comorbid BDD, with their body dysmorphic concerns being unrelated to weight and shape. BDD lifetime-prevalence was 15.0%. There was a high prevalence of dissatisfaction with nonweight-related body features such as skin, hair, teeth, nose, and height (20.8 to 53.5%). DISCUSSION Findings indicate that BDD is a frequent comorbid disorder in individuals with EDs. Furthermore, along with weight and body shape, nonweight-related appearance concerns are also common in individuals with EDs.

Abstract
BACKGROUND The prevalence, sociodemographic aspects, and clinical features of body dysmorphic disorder (BDD) in patients with obsessive-compulsive disorder (OCD) have been previously addressed in primarily relatively small samples. METHODS We performed a cross-sectional demographic and clinical assessment of 901 OCD patients participating in the Brazilian Research Consortium on Obsessive-Compulsive Spectrum Disorders. We used the Structured Clinical Interview for DSM-IV Axis I Disorders; Yale-Brown Obsessive-Compulsive Scale; Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS); Brown Assessment of Beliefs Scale; Clinical Global Impression Scale; and Beck Depression and Anxiety Inventories. RESULTS The lifetime prevalence of BDD was 12.1%. The individuals with comorbid BDD (OCD-BDD; n = 109) were younger than were those without it. In addition, the proportions of single and unemployed patients were greater in the OCD-BDD group. This group of patients also showed higher rates of suicidal behaviors; mood, anxiety, and eating disorders; hypochondriasis; skin picking; Tourette syndrome; and symptoms of the sexual/religious, aggressive, and miscellaneous dimensions. Furthermore, OCD-BDD patients had an earlier onset of OC symptoms; greater severity of OCD, depression, and anxiety symptoms; and poorer insight. After logistic regression, the following features were associated with OCD-BDD: current age; age at OCD onset; severity of the miscellaneous DY-BOCS dimension; severity of depressive symptoms; and comorbid social phobia, dysthymia, anorexia nervosa, bulimia nervosa, and skin picking. CONCLUSIONS Because OCD patients might not inform clinicians about concerns regarding their appearance, it is essential to investigate symptoms of BDD, especially in young patients with early onset and comorbid social anxiety, chronic depression, skin picking, or eating disorders.

Abstract
BACKGROUND Body integrity identity disorder (BIID) is a rare and unusual psychiatric condition characterized by a persistent desire to acquire a physical disability (e.g., amputation, paraplegia) since childhood that to date has not been formally described in the psychiatric nosology. Most BIID sufferers experience a chronic and dysphoric sense of inappropriateness regarding their being able-bodied, and many have been driven to actualize their desired disability through surreptitious surgical or other more dangerous methods. This review aims to characterize the history and phenomenology of this condition, to present its differential diagnosis, and to consider possible etiologies, treatment options, and ethical considerations. SAMPLING AND METHOD Review of the psychiatric and neurological literature. RESULTS A growing body of data suggests the existence of a discrete entity with onset by early adolescence and a negative impact on functioning. Parallel neurological conditions and preliminary experimental investigations suggest a possible neurobiological component in at least a portion of cases. While attempts at treatment have been described, no systematic evidence for efficacy has emerged. DISCUSSION BIID is a unique nosological entity with significant consequences for its sufferers and as such may warrant inclusion in some form in the forthcoming DSM-5 and ICD-11.

Abstract
This report prospectively examines the course of body dysmorphic disorder (BDD) for up to 8 years in a sample of 514 participants in the Harvard/Brown Anxiety Research Project, a naturalistic, longitudinal study of anxiety disorders. Diagnostic and Statistical Manual of Mental Disorders (4th ed.) BDD was assessed with a reliable semi-structured measure. For participants with BDD, severity of BDD symptoms was assessed with the Longitudinal Interval Follow-up Evaluation Psychiatric Status Rating scale. At the initial assessment, 17 participants (3.3%; 95% confidence interval = 1.8%-4.8%) had current BDD; 22 (4.3%; 95% confidence interval = 2.6%-6.1%) had lifetime BDD. Participants with BDD had significantly lower Global Assessment Scale scores than those without BDD, indicating poorer functioning. The probability of full recovery from BDD was 0.76, and probability of recurrence, once remitted, was 0.14 over the 8 years. In conclusion, among individuals ascertained for anxiety disorders, the probability of recovering from BDD was relatively high and probability of BDD recurrence was low.

Abstract
Obsessive-compulsive (OC)-spectrum conditions consist of neurological-motoric conditions, impulse-control disorders, and disorders associated with bodily preoccupation. This article is a review of some understudied OC-spectrum conditions, with particular focus on phenomenology and overlap with obsessive-compulsive disorder, etiology, treatment outcome, treatment refractory issues, and new developments in treatment research. The focus will be on representative disorders from each related area, namely, Tourette's syndrome, trichotillomania, skin-picking, and body dysmorphic disorder. Similarities among the disorders and areas in need of more research are discussed.

Abstract
Social anxiety disorder (SAD) and body dysmorphic disorder (BDD) are two separate, but conceptually overlapping nosological entities. In this review, we examine similarities between SAD and BDD in comorbidity, phenomenology, cognitive biases, treatment outcome, and cross-cultural aspects. Our review suggests that SAD and BDD are highly comorbid, show a similar age of onset, share a chronic trajectory, and show similar cognitive biases for interpreting ambiguous social information in a negative manner. Furthermore, research from treatment outcome studies have demonstrated that improvements in SAD were significantly correlated with improvements in BDD. Findings from cross-cultural research suggest that BDD may be conceived as a subtype of SAD in some Eastern cultures. Directions for future research and clinical implications of these findings are discussed.

Abstract
Body dysmorphic disorder (BDD) is a relatively common disorder that consists of a distressing or impairing preoccupation with imagined or slight defects in appearance. BDD is commonly considered to be an obsessive-compulsive spectrum disorder, based on similarities it has with obsessive-compulsive disorder. It is important to recognize and appropriately treat BDD, as this disorder is associated with marked impairment in psychosocial functioning, notably poor quality of life, and high suicidality rates. In this review, we provide an overview of research findings on BDD, including its epidemiology, clinical features, course of illness, comorbidity, psychosocial functioning, and suicidality. We also briefly review recent research on neural substrates and cognitive processing. Finally, we discuss treatment approaches that appear efficacious for BDD, with a focus on serotonin-reuptake inhibitors and cognitive-behavioral therapy.

Abstract
Cosmetic concerns are becoming increasingly common in view of the obsession with the perfect body and skin. Dermatologists are often seen to evaluate and treat these conditions. Therefore, it is important to acknowledge the existence of Body Dysmorphic Disorder, also known as dysmorphophobia. Despite being relatively common, this disorder has not been well researched. Sometimes causing impairment, the disease involves a distorted body image perception characterized by excessive preoccupation with a perceived defect. Most of the patients experience some degree of impairment in social or occupational functioning and, as a result of their obsessive concerns, they may develop compulsive behaviors. In severe cases, there is a risk of suicide. Most individuals do not acknowledge that their defect is minimal or nonexistent and seek out cosmetic treatments for a psychiatric disorder. The prevalence of this disorder among the general population ranges from 1 to 2 % and in dermatological and cosmetic surgery patients, from 2.9 to 16%. The training of professionals to systematically investigate, diagnose, and refer these patients to adequate psychiatric treatment is essential, considering the high prevalence of Body Dysmorphic Disorder in dermatological patients and the fact that cosmetic treatments rarely improve their condition.

Abstract
The obsessive-compulsive (OC) spectrum has been discussed in the literature for two decades. Proponents of this concept propose that certain disorders characterized by repetitive thoughts and/or behaviors are related to obsessive-compulsive disorder (OCD), and suggest that such disorders be grouped together in the same category (i.e. grouping, or "chapter") in DSM. This article addresses this topic and presents options and preliminary recommendations to be considered for DSM-V. The article builds upon and extends prior reviews of this topic that were prepared for and discussed at a DSM-V Research Planning Conference on Obsessive-Compulsive Spectrum Disorders held in 2006. Our preliminary recommendation is that an OC-spectrum grouping of disorders be included in DSM-V. Furthermore, we preliminarily recommend that consideration be given to including this group of disorders within a larger supraordinate category of "Anxiety and Obsessive-Compulsive Spectrum Disorders." These preliminary recommendations must be evaluated in light of recommendations for, and constraints upon, the overall structure of DSM-V.

Abstract
Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, has been described for more than a century and increasingly studied over the past several decades. This article provides a focused review of issues pertaining to BDD that are relevant to DSM-V. The review presents a number of options and preliminary recommendations to be considered for DSM-V: (1) Criterion A may benefit from some rewording, without changing its focus or meaning; (2) There are both advantages and disadvantages to adding a new criterion to reflect compulsive BDD behaviors; this possible addition requires further consideration; (3) A clinical significance criterion seems necessary for BDD to differentiate it from normal appearance concerns; (4) BDD and eating disorders have some overlapping features and need to be differentiated; some minor changes to DSM-IV's criterion C are suggested; (5) BDD should not be broadened to include body integrity identity disorder (apotemnophilia) or olfactory reference syndrome; (6) There is no compelling evidence for including diagnostic features or subtypes that are specific to gender-related, age-related, or cultural manifestations of BDD; (7) Adding muscle dysmorphia as a specifier may have clinical utility; and (8) The ICD-10 criteria for hypochondriacal disorder are not suitable for BDD, and there is no empirical evidence that BDD and hypochondriasis are the same disorder. The issue of how BDD's delusional variant should be classified in DSM-V is briefly discussed and will be addressed more extensively in a separate article.

Abstract
OBJECTIVE The objective is to evaluate the prevalence and associated clinical characteristics of eating disorders (ED) in patients with obsessive-compulsive disorder (OCD). METHOD This is a cross-sectional study comparing 815 patients with OCD. Participants were assessed with structured interviews and scales: SCID-I, Y-BOCS, Dimensional Y-BOCS, BABS, Beck Depression and Anxiety Inventories. RESULTS Ninety-two patients (11.3%) presented the following EDs: binge-eating disorders [= 59 (7.2%)], bulimia nervosa [= 16 (2.0%)], or anorexia nervosa [= 17 (2.1%)]. Compared to OCD patients without ED (OCD-Non-ED), OCD-ED patients were more likely to be women with previous psychiatric treatment. Mean total scores in Y-BOCS, Dimensional Y-BOCS, and BABS were similar within groups. However, OCD-ED patients showed higher lifetime prevalence of comorbid conditions, higher anxiety and depression scores, and higher frequency of suicide attempts than did the OCD-Non-ED group. Primarily diagnosed OCD patients with comorbid ED may be associated with higher clinical severity. DISCUSSION Future longitudinal studies should investigate dimensional correlations between OCD and ED.

Abstract
INTRODUCTION Body dysmorphic disorder (BDD) is an often severe disorder, but few treatment studies have been conducted. OBJECTIVE This pilot study explored the efficacy and safety of the antiepileptic medication levetiracetam for BDD. METHODS Seventeen subjects with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition BDD participated in a 12-week open-label levetiracetam trial. Subjects were assessed at regular intervals with standard measures. RESULTS In intent-to-treat analyses, scores on the Yale-Brown Obsessive Compulsive Scale Modified for BDD (BDD-YBOCS), the primary outcome measure, decreased from 32.5+/-4.7 at baseline to 21.5+/-11.0 at endpoint (P<.001). Approximately 60% (n=9) of subjects were responders (>30% decrease on the BDD-YBOCS). The mean time to response was 4.6+/-2.8 (range: 2-10) weeks. Scores also significantly improved on the Brown Assessment of Beliefs Scale, the Hamilton Rating Scale for Depression, the Global Assessment of Functioning Scale, and the Social and Occupational Functioning Assessment Scale. Scores did not significantly improve on the Quality of Life Enjoyment and Satisfaction Questionnaire, the Beck Anxiety Inventory, or the Social Phobia Inventory. The mean endpoint dose of levetiracetam was 2,044.1+/-1,065.2 (range: 250-3,000) mg/day, and it was relatively well-tolerated. CONCLUSION Randomized, double-blind placebo-controlled studies of levetiracetam for BDD are needed to confirm these preliminary findings.

Abstract
Knowledge concerning the classification of mental disorders progressed substantially with the use of DSM III-IV and IDCD 10 because it was based on observed data, with precise definitions. These classifications a priori avoided to generate definitions related to etiology or treatment response. They are based on a categorical approach where diagnostic entities share common phenomenological features. Modifications proposed or discussed are related to the weak validity of the classification strategy described above. (a) Disorders are supposed to be independent but the current coexistence of two or more disorders is the rule; (b) They also are supposed to have stability, however anxiety disorders most of the time precede major depression. For GAD age at onset, family history, biology and symptomatology are close to those of depression. As a consequence broader entities such as depression-GAD spectrum, panic-phobias spectrum and OCD spectrum including eating disorders and pathological gambling are taken into consideration; (c) Diagnostic categories use thresholds to delimitate a border with normals. This creates "subthreshold" conditions. The relevance of such conditions is well documented. Measuring the presence and severity of different dimensions, independent from a threshold, will improve the relevance of the description of patients pathology. In addition, this dimensional approach will improve the problems posed by the mutually exclusive diagnoses (depression and GAD, schizophrenia and depression); (d) Some disorders are based on the coexistence of different dimensions. Patients may present only one set of symptoms and have different characteristics, evolution and response to treatment. An example would be negative symptoms in Schizophrenia; (e) Because no etiological model is available and most measures are subjective, objective measures (cognitive, biological) and genetics progresses created important hopes. None of these measures is pathognomonic and most appear to be related to risk factors especially at certain periods when associated with environmental events. One of the major aims for a classification of patients is to identify groups to whom a best possible therapeutic strategy can be proposed. Drugs may improve fear extinction while the genetic and/or acquired avoidance may be called phobia. The basic mechanism and or the corresponding phenotype should appear in the classification. Progresses in early identification of disturbances by taking into account all the information available (prodromal symptoms, cognitive, biological, imaging, genetic, family information) are crucial for the future therapeutic strategy: prevention.
