RESUMEN

BACKGROUND: Olfactory reference syndrome (ORS) is an underrecognized, understudied, and often severe psychiatric disorder characterized by a prominent and distressing or impairing preoccupation with a false belief of emitting an offensive body odor. As this condition has only recently been recognized in the International Classification of Diseases (the 11th Edition), no empirical evidence exists about the underlying features and etiology of the disorder. OBJECTIVE: To examine the neuropsychological and olfactory functioning of individuals with ORS and address whether there is central nervous system or sensory dysfunction associated with the condition. METHODS: In this preliminary investigation, 9 consecutive participants with ORS completed a structured clinical interview and neuropsychological and olfaction evaluations. RESULTS: A proportion of individuals with ORS displayed deficits in aspects of cognitive functioning (i.e., processing speed, executive functioning, recognition memory bias for ORS-related words), olfaction functioning (i.e., odor detection and discrimination), and emotional processing. CONCLUSIONS: Based on these preliminary findings of cognitive, olfaction, and emotional processing deficits in individuals with ORS, further neuropsychological and olfaction studies are needed that better characterize this understudied patient group and address this study's limitations.

RESUMEN

Background: With the approval of disease-modifying treatments (DMTs) for early Alzheimer's disease (AD), there is an increased need for efficient and non-invasive detection methods for cerebral amyloid-ß (Aß) pathology. Current methods, including positron emission tomography (PET) and cerebrospinal fluid (CSF) analysis, are costly and invasive methods that may limit access to new treatments. Plasma tau phosphorylated at threonine-217 (P-tau217) presents a promising alternative, yet optimal cutoffs for treatment eligibility with DMTs like aducanumab require further investigation. This study evaluates the efficacy of one- and two-cutoff strategies for determining DMT eligibility at the Butler Hospital Memory & Aging Program (MAP). Methods: In this retrospective, cross-sectional diagnostic cohort study, we first developed P-tau217 cutoffs using site-specific training data and BioFINDER-2, which were then tested in potential DMT candidates from Butler MAP (total n = 150). ROC analysis was used to calculate the area under the curve (AUC) and accuracy of P-tau217 interpretation strategies, using Aß-PET/CSF testing as the standard of truth. Results: Potential DMT candidates at Butler MAP (n = 50), primarily diagnosed with mild cognitive impairment (n = 29 [58%]) or mild dementia (21 [42%]), were predominantly Aß-positive (38 [76%]), and half (25 [50%]) were subsequently treated with aducanumab. Elevated P-tau217 predicted cerebral Aß positivity in potential DMT candidates (AUC = 0.97 [0.92-1]), with diagnostic accuracy ranging from 0.88 (0.76-0.95, p = 0.028) to 0.96 (0.86-1, p < .001). When using site-specific cutoffs, a subset of DMT candidates (10%) exhibited borderline P-tau217 (between 0.273 and 0.399 pg/mL) that would have potentially required from confirmatory testing. Conclusions: This study, which included participants treated with aducanumab, confirms the utility of one- and two-cutoff strategies for interpreting plasma P-tau217 in assessing DMT eligibility. Using P-tau217 could potentially replace more invasive diagnostic methods, and all aducanumab-treated participants would have been deemed eligible based on P-tau217. However, false positives remain a concern, particularly when applying externally derived cutoffs that exhibited lower specificity which could have led to inappropriate treatment of Aß-negative participants. Future research should focus on prospective validation of P-tau217 cutoffs to enhance their generalizability and inform standardized treatment decision-making across diverse populations.

RESUMEN

OBJECTIVE: Age at onset is an important clinical feature of all disorders. However, no prior studies have focused on this important construct in body dysmorphic disorder (BDD). In addition, across a number of psychiatric disorders, early age at disorder onset is associated with greater illness severity and greater comorbidity with other disorders. However, clinical correlates of age at onset have not been previously studied in BDD. METHODS: Age at onset and other variables of interest were assessed in two samples of adults with DSM-IV BDD; sample 1 consisted of 184 adult participants in a study of the course of BDD, and sample 2 consisted of 244 adults seeking consultation or treatment for BDD. Reliable and valid measures were used. Subjects with early-onset BDD (age 17 or younger) were compared to those with late-onset BDD. RESULTS: BDD had a mean age at onset of 16.7 (SD=7.3) in sample 1 and 16.7 (SD=7.2) in sample 2. 66.3% of subjects in sample 1 and 67.2% in sample 2 had BDD onset before age 18. A higher proportion of females had early-onset BDD in sample 1 but not in sample 2. On one of three measures in sample 1, those with early-onset BDD currently had more severe BDD symptoms. Individuals with early-onset BDD were more likely to have attempted suicide in both samples and to have attempted suicide due to BDD in sample 2. Early age at BDD onset was associated with a history of physical violence due to BDD and psychiatric hospitalization in sample 2. Those with early-onset BDD were more likely to report a gradual onset of BDD than those with late-onset in both samples. Participants with early-onset BDD had a greater number of lifetime comorbid disorders on both Axis I and Axis II in sample 1 but not in sample 2. More specifically, those with early-onset BDD were more likely to have a lifetime eating disorder (anorexia nervosa or bulimia nervosa) in both samples, a lifetime substance use disorder (both alcohol and non-alcohol) and borderline personality disorder in sample 1, and a lifetime anxiety disorder and social phobia in sample 2. CONCLUSIONS: BDD usually began during childhood or adolescence. Early onset was associated with gradual onset, a lifetime history of attempted suicide, and greater comorbidity in both samples. Other clinical features reflecting greater morbidity were also more common in the early-onset group, although these findings were not consistent across the two samples.

RESUMEN

The Brown Assessment of Beliefs Scale (BABS) is a widely used measure that assesses insight/delusionality-an important dimension of psychopathology-both dimensionally and categorically (e.g., delusional versus nondelusional). The BABS has been shown to have good psychometric properties in a number of disorders, but sample sizes were small. In the present study, 327 subjects with body dysmorphic disorder (BDD) were interviewed with the BABS to assess insight regarding appearance beliefs. Other measures were administered. Intraclass correlation coefficients demonstrated excellent interrater reliability and test-retest reliability; internal consistency was strong. Principal components factor analysis identified one factor accounting for 60% of the variance. Analyses with measures of severity of BDD, depressive symptoms, and general psychopathology indicated good discriminant validity. Among the treated subjects, the BABS was sensitive to change but not identical to improvement in symptom severity. These findings provide further evidence that the BABS is a reliable and valid measure of insight/delusionality.

RESUMEN

Because information technologies are increasingly used to improve clinical research and care, personal health information (PHI) has wider dissemination than ever before. The 21st Century Cures Act in the United States now requires patient access to many components of the electronic health record (EHR). Although these changes promise to enhance communication and information sharing, they also bring higher risks of unwanted disclosure, both within and outside of health systems. Having preclinical Alzheimer disease (AD), where biological markers of AD are identified before the onset of any symptoms, is sensitive PHI. Because of the melding of ideas between preclinical and "clinical" (symptomatic) AD, unwanted disclosure of preclinical AD status can lead to personal harms of stigma, discrimination, and changes to insurability. At present, preclinical AD is identified mainly in research settings, although the consensus criteria for a clinical diagnosis may soon be established. There is not yet adequate legal protection for the growing number of individuals with preclinical AD. Some PHI generated in preclinical AD trials has clinical significance, necessitating urgent evaluations and longitudinal monitoring in care settings. AD researchers are obligated to both respect the confidentiality of participants' sensitive PHI and facilitate providers' access to necessary information, often requiring disclosure of preclinical AD status. The AD research community must continue to develop ethical, participant-centered practices related to confidentiality and disclosure, with attention to sensitive information in the EHR. These practices will be essential for translation into the clinic and across health systems and society at large.

RESUMEN

Persons with body dysmorphic disorder (BDD) frequently seek surgical and minimally invasive (MI) treatments to improve their appearance, but few studies have evaluated patient characteristics and outcomes. Surgical/MI treatment histories of 200 persons with BDD were cross-sectionally/retrospectively evaluated. Clinical and demographic characteristics of persons who received such treatments (n = 42) were compared to those who had not (n = 158). Outcomes and reasons for nonreceipt of requested procedures were examined. Receivers of surgical/MI treatments reported less severe current BDD symptoms and delusionality than persons who did not receive such treatments. Surgical/MI treatments were more likely than other cosmetic procedures to decrease preoccupation with the treated body part; however, overall BDD severity improved with only 2.3% of treatments. Cost and physician refusal were the most common reasons requested treatment was not received. However, physicians were more likely to provide requested surgical/MI treatment than other types of requested cosmetic treatment, despite the poor longer-term outcome.

RESUMEN

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.

RESUMEN

The Sexual Homicide Crime Scene Rating Scale for Sexual Sadism (SADSEX-SH) is a rating scale which dimensionally measures the degree of offender sexual sadism in suspected sexual homicide cases. Scoring is accomplished using crime scene and related investigative information. Preliminary norms for the SADSEX-SH prototype indicate that it correctly classified offenders with and without sexual sadism. This study further assessed SADSEX-SH sensitivity, specificity, and inter-rater reliability by comparing a larger sample of male sexual homicide offenders with (n = 20) and without (n = 20) sexual sadism. Two items generally undetectable at crime scenes were removed from the originally proposed 10-item scale, resulting in a final 8-item version. SADSEX-SH total scores for the two groups significantly differed (7.7 ± 3.5, range = 2-14 vs. 2.6 ± 2.0, range = 0-7, t = 5.58, p < .001). Inter-rater reliability was excellent (intraclass correlation coefficients [ICCs] = 0.6-1.0). Using a revised cutoff score of 6, sensitivity was 70.0% and specificity was 90%. This revised scale may prove useful for investigators, clinicians, and institutional professionals in helping to identify and address sexual sadism in sexual homicide offenders.

RESUMEN

OBJECTIVE: Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with an imagined or slight defect in appearance, is an often-severe, understudied disorder. We determined BDD's prevalence and clinical features on a general adult psychiatric inpatient unit. To our knowledge, only one previous prevalence study has been done in this setting. METHOD: One hundred patients completed 3 self-report measures: the Body Dysmorphic Disorder Questionnaire (BDD-Q), Beck Anxiety Inventory (BAI) and Center for Epidemiologic Studies Depression Scale (CES-D). Those who screened positive for BDD were interviewed to confirm DSM-IV BDD and its clinical features. Charts were reviewed for demographic and clinical information. RESULTS: BDD was diagnosed in 16.0% (95% CI=8.7-23.3%) (n=16) of patients. A high proportion of those with BDD reported that BDD symptoms contributed to suicidality. Patients revealed BDD symptoms to a mean of only 15.1%+/-33.7% lifetime mental health clinicians; only one (6.3%) reported symptoms to his current inpatient psychiatrist. Most did not disclose their symptoms due to embarrassment. Those with BDD were younger (P=.008) and had higher CES-D scores (P=.008). The two groups did not significantly differ on BAI score, demographic characteristics or discharge diagnoses. CONCLUSIONS: BDD is relatively common but underdiagnosed in psychiatric inpatients and is associated with more severe depressive symptoms.

RESUMEN

OBJECTIVE: Body dysmorphic disorder (BDD) is relatively common and appears to be associated with marked impairment in psychosocial functioning. Previous reports, however, did not investigate occupational functioning in detail, assess impairment specifically in occupational functioning using standardized measures in a nontreatment seeking sample, or examine correlates of occupational impairment. METHODS: Occupational functioning and other clinical variables were assessed in 141 adults with BDD. Measures included the Range of Impaired Functioning Tool and other reliable and valid self-report and interviewer-administered measures. RESULTS: Fewer than half of subjects were working full-time, and 22.7% were receiving disability pay. Thirty-nine percent of the sample reported not working in the past month because of psychopathology. Of those subjects who worked in the past month, 79.7% reported impairment in work functioning because of psychopathology. Adults with BDD who were not working because of psychopathology were comparable to subjects who were working in most demographic variables, delusionality of BDD beliefs, and duration of BDD. However, compared to subjects who worked in the past month, those not currently working because of psychopathology had more severe BDD and more chronic BDD. They also were more likely to be male, had less education, and had more severe depressive symptoms, a higher rate of certain comorbid disorders, poorer current social functioning and quality of life, a higher rate of lifetime suicidality, and were more likely to have been psychiatrically hospitalized. CONCLUSIONS: A high proportion of individuals with BDD were unable to work because of psychopathology; most who worked reported impairment in occupational functioning. Certain clinical variables, including more severe and chronic BDD, were associated with not working.

RESUMEN

BACKGROUND: Body dysmorphic disorder (BDD) and major depressive disorder (MDD) appear highly comorbid. However, MDD in individuals with BDD has received little investigation. METHODS: The prevalence and characteristics of comorbid MDD were assessed in 178 BDD subjects. BDD subjects with current comorbid MDD (n=68) were compared to BDD subjects without current comorbid MDD (n=96) on demographic and clinical characteristics. Predictors of current MDD were determined using logistic regression. RESULTS: 74.2% of subjects had lifetime MDD, and 38.2% had current MDD. The melancholic subtype was most common, and a majority of depressed subjects had recurrent episodes. Mean onset of BDD occurred at a younger age than MDD. Subjects with current comorbid MDD had many similarities to those without MDD, although those with comorbid MDD had more severe BDD. Subjects with comorbid MDD were also more likely to have an anxiety or personality disorder, as well as a family history of MDD. They also had greater social anxiety, suicidality, and poorer functioning and quality of life. Current MDD was independently predicted by a personality disorder and more severe BDD. LIMITATIONS: It is unclear how generalizable the results are to the community or to subjects ascertained for MDD who have comorbid BDD. The study lacked a comparison group such as MDD subjects without BDD. CONCLUSIONS: MDD is common in individuals with BDD. Individuals with current MDD had greater morbidity in some clinically important domains, including suicidality, functioning, and quality of life. A personality disorder and more severe BDD independently predicted the presence of current MDD.

RESUMEN

OBJECTIVE: To determine the prevalence of weight concerns in individuals with BDD, and to examine similarities and differences between those with and those without weight concerns. METHOD: We assessed 200 participants with BDD for clinically significant weight concerns and compared those with weight concerns (in addition to other body area concerns) to those without weight concerns on measures of BDD symptoms, other symptom severity, comorbidity, suicidality, functioning, and quality of life. RESULTS: 58 (29.0%) participants had weight concerns. Participants with weight concerns were younger, more likely to be female, and had more body areas of concern; a higher frequency of certain BDD behaviors, suicide attempts, and comorbidity; greater body image disturbance and depression; and poorer social functioning. The two groups were similar on other measures. DISCUSSION: Weight concerns in BDD deserve further study, as they appear relatively common and are associated with greater symptom severity and psychopathology in several domains.

RESUMEN

OBJECTIVE: Cross-sectional/retrospective data have indicated that individuals with body dysmorphic disorder (BDD) have high rates of suicidal ideation and attempts. However, no study, to the authors' knowledge, has prospectively examined suicidality in BDD. METHOD: In the first prospective study of BDD's course, the authors examined suicidality in 185 subjects for up to 4 years. RESULTS: Suicidal ideation was reported by a mean of 57.8% of the subjects per year, and a mean of 2.6% attempted suicide per year. Two subjects (0.3% per year) completed suicide. CONCLUSIONS: Individuals with BDD have high rates of suicidal ideation and attempts. The completed suicide rate is preliminary but suggests that the rate of completed suicide in BDD is markedly high.

RESUMEN

OBJECTIVE: This study investigated the course of body dysmorphic disorder (BDD), a relatively common and severe disorder, in the first prospective follow-up study, to the authors' knowledge. METHOD: In this study, the authors obtained data with the Longitudinal Interval Follow-Up Evaluation on weekly BDD symptom status and treatment received over 1 year for 183 broadly ascertained subjects. Probabilities of full remission, partial remission, and relapse during this year were examined. Full remission was defined as minimal or no BDD symptoms and partial remission, as meeting less than full DSM-IV criteria for at least 8 consecutive weeks. Relapse was defined as meeting full BDD criteria for at least 2 consecutive weeks after attaining partial or full remission from BDD. RESULTS: Over 1 year, the probability of full remission from BDD was only 0.09, and the probability of partial remission was 0.21. Although 84.2% of the subjects received mental health treatment during the 1-year period, mean BDD severity scores during the year reflected full DSM-IV criteria for BDD, and the mean proportion of time that the subjects met full BDD criteria was 80%. Gender and ethnicity did not significantly predict remission from BDD. Among the subjects whose BDD symptoms partially or fully remitted, the probability of relapse was 0.15. CONCLUSIONS: These findings indicate that BDD tends to be chronic. Remission probabilities were lower than reported for mood disorders, most anxiety disorders, and personality disorders in studies with similar methods.

RESUMEN

OBJECTIVE: The objective of this study was to examine the prevalence and clinical correlates of pathological skin picking (PSP) in a large sample of individuals with body dysmorphic disorder (BDD). METHOD: One hundred seventy-six individuals with BDD (71.0% women; mean age, 32.5+/-12.3 years) were assessed with respect to comorbidity, BDD severity, delusionality (insight), quality of life and social/occupational functioning, using reliable and valid measures. All variables were compared in BDD subjects with and without lifetime PSP. RESULTS: About 44.9% of subjects reported lifetime PSP, and 36.9% reported current PSP secondary to BDD. BDD subjects with PSP were more likely to be female, to have skin preoccupations, to have comorbid trichotillomania or a personality disorder, to camouflage with makeup and to seek and receive nonpsychiatric (e.g., dermatological) treatment for their skin preoccupations. CONCLUSION: There is a high prevalence of PSP among individuals with BDD, and clinicians should be aware of the clinical correlates of this problematic behavior.

RESUMEN

Body dysmorphic disorder (BDD) usually begins during adolescence, but its clinical features have received little investigation in this age group. Two hundred individuals with BDD (36 adolescents; 164 adults) completed interviewer-administered and self-report measures. Adolescents were preoccupied with numerous aspects of their appearance, most often their skin, hair, and stomach. Among the adolescents, 94.3% reported moderate, severe, or extreme distress due to BDD, 80.6% had a history of suicidal ideation, and 44.4% had attempted suicide. Adolescents experienced high rates and levels of impairment in school, work, and other aspects of psychosocial functioning. Adolescents and adults were comparable on most variables, although adolescents had significantly more delusional BDD beliefs and a higher lifetime rate of suicide attempts. Thus, adolescents with BDD have high levels of distress and rates of functional impairment, suicidal ideation, and suicide attempts. BDD's clinical features in adolescents appear largely similar to those in adults.

RESUMEN

OBJECTIVE: No published studies have examined childhood abuse and neglect in body dysmorphic disorder (BDD). This study examined the prevalence and clinical correlates of abuse and neglect in individuals with this disorder. METHODS: Seventy-five subjects (69.3% female, mean age=35.4+/-12.0) with DSM-IV BDD completed the Childhood Trauma Questionnaire and were interviewed with other reliable and valid measures. RESULTS: Of these subjects, 78.7% reported a history of childhood maltreatment: emotional neglect (68.0%), emotional abuse (56.0%), physical abuse (34.7%), physical neglect (33.3%), and sexual abuse (28.0%). Forty percent of subjects reported severe maltreatment. Among females (n=52), severity of reported abuse and neglect were .32-.57 standard deviation units higher than norms for a health maintenance organization (HMO) sample of women. Severity of sexual abuse was the only type of maltreatment significantly associated with current BDD severity (r=.23, p=.047). However, severity of sexual abuse did not predict current BDD severity in a simultaneous multiple regression analysis with age and current treatment status. There were other significant associations with childhood maltreatment: history of attempted suicide was related to emotional (p=.004), physical (p=.014), and sexual abuse (p=.038). Childhood emotional abuse was associated with a lifetime substance use disorder (r=.26, p=.02), and physical abuse was negatively associated with a lifetime mood disorder (r=-.37, p=.001). CONCLUSIONS: A high proportion of individuals with BDD reported childhood abuse and neglect. Certain types of abuse and neglect appear modestly associated with BDD symptom severity and with gender, suicidality, and certain disorders.

RESUMEN

OBJECTIVE: Body dysmorphic disorder is common, distressing, and often severely impairing. Serotonin reuptake inhibitors appear efficacious, but the few existing pharmacotherapy studies were short term (≤4 months), and no relapse prevention studies or continuation phase studies have been conducted to the authors' knowledge. The authors report results from the first relapse prevention study in body dysmorphic disorder. METHOD: Adults (N=100) with DSM-IV body dysmorphic disorder received open-label escitalopram for 14 weeks (phase 1); 58 responders were then randomized to double-blind continuation treatment with escitalopram versus switch to placebo for 6 months (phase 2). Reliable and valid outcome measures were utilized. RESULTS: In phase 1, 67.0% of treated subjects and 81.1% of subjects who completed phase 1 responded to escitalopram. Body dysmorphic disorder severity (in both the intent-to-treat and the completer groups) and insight, depressive symptoms, psychosocial functioning, and quality of life significantly improved from baseline to end of phase 1. In phase 2, time to relapse was significantly longer with escitalopram than with placebo treatment (hazard ratio=2.72, 95% CI=1.01-8.57). Phase 2 relapse proportions were 18% for escitalopram and 40% for placebo. Among escitalopram-treated subjects, body dysmorphic disorder severity significantly decreased over time during the continuation phase, with 35.7% of subjects showing further improvement. There were no significant group differences in body dysmorphic disorder severity or insight, depressive symptoms, psychosocial functioning, or quality of life. CONCLUSIONS: Continuation-phase escitalopram delayed time to relapse, and fewer escitalopram-treated subjects relapsed than did placebo-treated subjects. Body dysmorphic disorder severity significantly improved during 6 additional months of escitalopram treatment following acute response; more than one-third of escitalopram-treated subjects experienced further improvement.

RESUMEN

OBJECTIVE: Because suicidality in body dys-morphic disorder (BDD) has received little investigation, this study examined rates, correlates, predictors, and other aspects of suicidal ideation and suicide attempts in this disorder. METHOD: From January 2001 to June 2003, 200 subjects with DSM-IV BDD recruited from diverse sources were assessed with standard measures. RESULTS: Subjects had high rates of lifetime suicidal ideation (78.0%) and suicide attempts (27.5%). Body dysmorphic disorder was the primary reason for suicidal ideation in 70.5% of those with a history of ideation and nearly half of subjects with a past attempt. Suicidal subjects often did not reveal their BDD symptoms to their clinician. In univariate analyses, both suicidal ideation and suicide attempts were associated with lifetime functional impairment due to BDD (p < .001), current functional impairment (p < .001 to < .05), lifetime bipolar disorder (p < .05), any personality disorder (p < .05 to .001), and comorbid borderline personality disorder (p < .01 to < .001). A history of suicidal ideation (but not suicide attempts) was additionally associated with comorbid lifetime major depression (p = .001). A history of suicide attempts (but not suicidal ideation) was additionally associated with delusional appearance beliefs (p = .01) and lifetime posttraumatic stress disorder (PTSD), an eating disorder, or a substance use disorder (p < .001 to < .05). In logistic regression analyses, suicidal ideation was significantly predicted by comorbid major depression (p = .010) and greater lifetime impairment due to BDD (p = .003); suicide attempts were significantly predicted by PTSD (p = .011), a substance use disorder (p = .011), and greater lifetime impairment due to BDD (p = .005). CONCLUSION: Individuals with BDD have high rates of suicidal ideation and suicide attempts. Lifetime impairment due to BDD and certain comorbid disorders are associated with suicidality.
