COGNITIVE NEUROSCIENCE AND NEUROIMAGING 2023; 8:909-917. [PMID: 34688924 PMCID: PMC9037993 DOI: 10.1016/j.bpsc.2021.10.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 10/05/2021] [Accepted: 10/05/2021] [Indexed: 04/23/2023]
Abstract
BACKGROUND Individuals with body dysmorphic disorder (BDD) misperceive that they have prominent defects in their appearance, resulting in preoccupations, time-consuming rituals, and distress. Previous neuroimaging studies have found abnormal activation patterns in the extrastriate visual cortex, which may underlie experiences of distorted perception of appearance. Correspondingly, we investigated gray matter volumes in individuals with BDD in the early extrastriate visual cortex using cytoarchitectonically defined maps that were previously derived from postmortem brains. METHODS We analyzed T1-weighted magnetic resonance imaging data from 133 unmedicated male and female participants (BDD: n = 65; healthy control subjects: n = 68). We used cytoarchitectonically defined probability maps for the early extrastriate cortex, consisting of areas corresponding to V2, V3d, V3v/VP, V3a, and V4v. Gray matter volumes were compared between groups, supplemented by testing associations with clinical symptoms. RESULTS The BDD group exhibited significantly larger gray matter volumes in the left and right early extrastriate cortex. Region-specific follow-up analyses revealed multiple subregions showing larger volumes in BDD, significant in the left V4v. There were no significant associations after corrections for multiple comparisons between gray matter volumes in early extrastriate cortex and BDD symptoms, comorbid symptoms, or duration of illness. CONCLUSIONS Greater volumes of the early extrastriate visual cortex were evident in those with BDD, which aligns with outcomes of prior studies revealing BDD-specific functional abnormalities in these regions. Enlarged volumes of the extrastriate cortex in BDD might manifest during neurodevelopment, which could predispose individuals to aberrant visual perception and contribute to the core phenotype of distortion of perception for appearance.

Abstract
Body dysmorphic disorder (BDD) is a mental disorder that involves a distressing preoccupation with a perceived defect in physical appearance, associated with excessive or repetitive behaviours or mental acts aimed at camouflaging, checking or 'improving' the perceived area of concern. BDD is relatively common, affecting at least 2% of the population world-wide, yet is poorly understood. Professor Susan Rossell has produced a substantial body of influential research, which has improved our understanding of BDD. This includes a more comprehensive understanding of the phenomenology, neurocognition and neurobiology, as well as significant treatment advances. This work will be reviewed in this commentary.

Abstract
Body dysmorphic disorder (BDD) is a debilitating mental health condition that presently affects ~2% of the general population. Individuals with BDD experience distressing preoccupations regarding one or more perceived defects in their physical appearance. These preoccupations and perceived distortions can have a profound impact on key areas of social functioning and psychological health. Individuals' BDD origins have not been explored in significant depth and have been, often unhelpfully, conflated with social media usage and exposure to idealistic imagery of the body. Such generalisations fail to acknowledge the complexity of BDD development and onset, highlighting the importance of moving towards an understanding of people's implicit theories regarding their own experience. It is therefore essential to gain insight into how individuals make sense of the experiences which they believe led to the development and onset of BDD. The aim of this exploratory study was to elicit and phenomenologically analyse the accounts of individuals with lived experience of BDD in order to examine their beliefs about its origins and understand how they navigate the world with a distorted sense of self. Participants provided written and verbal accounts regarding both their BDD onset and experiences of living with the disorder. Both components of the study were analysed using Interpretative Phenomenological Analysis. Four main themes were generated from the data: Exposure to bullying and external critique of appearance; Experiencing rejection, shame, and a sense of not being enough; Developing an awareness of the solidification of concerns, and Learning about and reflecting upon triggers. Participants attributed their BDD onset to adverse experiences such as childhood bullying, receiving appearance-focused criticism, rejection and being subjected to emotional and physical abuse. The findings from this study highlight the complexity of BDD development and onset in individuals, and the need for appropriate care and treatment for those affected by BDD.

Abstract
BACKGROUND What drives patients who are unhappy despite good results? Adverse childhood experiences are common, can impair adult health, and can cause body shame. Neither adverse childhood experiences nor body shame has been studied in surgical patients. The authors report adverse childhood experience prevalences in a plastic surgical population and investigate associations from adverse childhood experiences to body shame and to postoperative dissatisfaction. METHODS Two hundred eighteen consecutive patients (86 percent aesthetic and 14 percent reconstructive) completed the Adverse Childhood Experiences Survey and the Experience of Shame Scale. A one-sample test of proportions, logistic regression, and mediation analysis assessed outcomes. RESULTS Compared to the Kaiser/Centers for Disease Control and Prevention medical population, our patients had higher overall adverse childhood experience prevalences (79.8 percent versus 64 percent), emotional abuse (41 percent versus 11 percent), emotional neglect (38 percent versus 15 percent), family substance abuse (36 percent versus 27 percent), and family mental illness (29 percent versus 19 percent, all p < 0.001). Fifty-two percent of our patients had body shame. Adverse Childhood Experiences score predicted body shame (OR, 1.22; p = 0.003). Compared to unshamed patients, body shame was associated with more adverse childhood experiences (85 percent versus 72 percent), higher median Adverse Childhood Experiences score (3.5 versus 2), more cosmetic operations (three versus zero), more health problems (three versus two), higher antidepressant use (39 percent versus 19 percent), substance abuse history (16 percent versus 5 percent), and demands for additional pain medication (18 percent versus 5 percent). Body shame predicted requests for surgical revision (49 percent versus 17 percent; OR, 4.61; all p ≤ 0.0001). CONCLUSIONS Adverse childhood experience were common in our patients. Adverse Childhood Experiences score predicted body shame, which predicted revision requests. If body shame preceded and drove surgery, revision requests were likely. Patients desiring revisions had recognizable characteristics. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, III.

Abstract
Although there has been an increment in neuroimaging research in somatoform disorders (SD), to date little is known about the neural correlates of these diseases. Therefore, in this systematic, review we aimed at summarizing the existing evidence of structural brain alterations in SD as per DSM-IV and DSM-5 criteria. Three electronic databases (Scopus, PubMed and Web of Science) were searched. Only case-control studies using structural neuroimaging were included. Forty-five out of 369 articles fulfilled inclusion criteria and were reviewed. Compared to controls, subjects with SD showed morphological alterations encompassing motor, limbic and somatosensory circuits. Although far from being conclusive, the results suggested that SD are characterized by selective alterations of large-scale brain networks implicated in cognitive control, emotion regulation and processing, stress and somatic-visceral perception. This review highlights the need for further multimodal neuroimaging studies with longitudinal designs, in larger and better-characterized samples, to elucidate the temporal and causal relationship between neuroanatomical changes and SD, which is paramount for informing tailored treatments.

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 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
Bulimia nervosa (BN) is a psychiatric illness defined by preoccupation with body image (cognitive 'symptoms'), binge eating and compensatory behaviors. Although diagnosed BN has been related to grey matter alterations, characterization of brain structure in women with a range of BN symptoms has not been made. This study examined whether cortical thickness (CT) values scaled with severity of BN cognitions in 33 women with variable BN pathology. We then assessed global structural connectivity (SC) of CT to determine if individual differences in global SC relate to BN symptom severity. We used the Eating Disorder Examination Questionnaire (EDE-Q) as a continuous measure of BN symptom severity. EDE-Q score was negatively related to global CT and local CT in the left middle frontal gyrus, right superior frontal gyrus and bilateral orbitofrontal cortex (OFC) and temporoparietal regions. Moreover, cortical thinning was most pronounced in regions with high global connectivity. Finally, individual contributions to global SC at the group level related to EDE-Q score, where increased EDE-Q score correlated with reduced connectivity of the left OFC and middle temporal cortex and increased connectivity of the right superior parietal lobule. Findings represent the first evidence of cortical thinning that relates to cognitive BN symptoms.
