Clinical features and correlates of major depressive disorder in individuals with body dysmorphic disorder.

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.

Response to light therapy in seasonal affective disorder: personality disorders and temperament as predictors of outcome.

Outcome after 6 days of morning light therapy in subjects fulfilling criteria for winter seasonal affective disorder (SAD) was examined. Responders had significantly fewer previous episodes of SAD. Patients with a diagnosis of any DSM-III-R, axis II personality disorder, were significantly less likely to respond to light therapy than patients without axis II pathology. Poor treatment outcome was also significantly associated with: one or more personality disorders in cluster C, avoidant personality disorder, high number of positive criteria for self-defeating personality disorder and high score on the harm avoidance scale of the Tridimensional Personality Questionnaire. Temperament accounted for 25% of the variance in treatment outcome.

Outcome for adjustment disorder with depressed mood: comparison with other mood disorders.

BACKGROUND: A review of the research literature on the diagnostic category of adjustment disorder indicates that its construct validity has not been established. Nevertheless, the diagnosis is made frequently, with an estimated incidence of 5-21% in psychiatric consultation services for adults. METHODS: Retrospective data was used to evaluate the construct validity of the adjustment disorder diagnostic category. The data primarily consisted of SF-36 Health Status Survey responses by a large group of adult psychiatric outpatients before treatment and again six months after beginning treatment. Subjects were divided into five diagnostic groups, and MANOVA, MANCOVA and chi square were used to clarify relationships among diagnoses, sociodemographic data and SF-36 scores. RESULTS: Diagnostic categories were significantly different at baseline, but did not differ in terms of outcome at six-months follow-up. There was a significant gender difference at baseline and a significant difference in gender distribution across diagnostic categories. LIMITATIONS: Structured interviews were not used for initial diagnoses, nor is there an estimate of the reliability of diagnoses among the clinicians. The patient attrition rate for six-months follow-up data was about 50%. Finally, patients received individualized treatment, with some patients receiving both medication and psychotherapy. CONCLUSIONS: Female patients were significantly more likely to be diagnosed with major depression or dysthymia than with an adjustment disorder. Females were also more likely than males to score lower on the mental health related scales of the SF-36 at admission. Patients diagnosed with an adjustment disorder scored higher on all SF-36 scales than did the other diagnostic groups at baseline and again at follow-up. There was no significant difference among diagnostic groups with regard to treatment outcome, suggesting that the adjustment disorder group can benefit as much as the other groups from treatment.

Distinguishing generalized anxiety disorder, panic disorder, and mixed anxiety states in older treatment-seeking adults.

Eighty treatment-seeking adults age 60 or over with panic disorder, generalized anxiety disorder, and mixed anxiety states (generalized anxiety with panic attacks, panic disorder with secondary generalized anxiety) completed a clinical assessment and battery of self report measures. Several hypotheses were tested from the domains of distinguishing symptoms, associated features, and rates of comorbidity with other disorders. Greater between- than within-group variance was found on a subset of measures suggesting that the distinction between GAD and PD is generally valid in the older adult population. Higher scores on measures of sympathetic arousal, agoraphobic avoidance, and rates of comorbid somatization disorder and alcohol dependence distinguished those with PD from those with GAD. Higher scores on measures of depression and hostility, but not trait anxiety or worry, distinguished the GAD group. Results indicate that distinguishing features of GAD and PD in older treatment-seeking adults may be fewer and slightly different from those of younger adults.

The links between body dysmorphic disorder and eating disorders.

The aim of the study was to search for a body dysmorphic disorder (BDD) period preceding the symptoms meeting the criteria of either anorexia or bulimia nervosa, and an evaluation of the prevalence of BDD symptoms in a control group of girls without any eating disorder. Ninety-three girls (12-21 years old ) were included in the study (36 with anorexia nervosa, 17 with bulimia nervosa and 40 healthy controls). The Structured Clinical Interview (SCID), including the BDD module, and a novel questionnaire (for the presence of preceding life events) were used. We found the symptoms of BDD in 25% of anorexia nervosa sufferers for at least six months before observing a clear eating disorder picture. Moreover, other mental disorders were also present among these patients. The results may support the idea that BDD and anorexia nervosa both belong to either OCD or affective disorders spectra.

Social phobia and avoidant personality disorder: one spectrum disorder?

General population data was used to examine if empirically derived subtypes of social phobia with and without avoidant personality disorder (APD) could be differentiated on self-report measures of anxiety severity, level of global functioning and the number of fulfilled diagnostic criteria for other personality disorders. DSM-IV diagnoses of social phobia, APD and indices of other personality disorders were determined by means of a postal survey. The presence of APD was associated with compromised functional status and a higher frequency of fulfilled diagnostic criteria for additional personality disorders. However, APD did not modify the effect of social phobia subtypes on anxiety severity, level of global functioning or number of personality disorder indices. The presence of comorbid APD in social phobics seems to predict a global functioning decrement independent of anxiety severity. The results imply that social phobia and APD may represent different points on a severity continuum rather than easily defined discreet categories suggesting that social phobia and APD may represent a spectrum of anxiety symptoms related to social anxiety.

Is childhood oppositional defiant disorder a precursor to adolescent conduct disorder? Findings from a four-year follow-up study of children with ADHD.

OBJECTIVE: To evaluate the overlap between attention-deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD), addressing whether ODD is subsyndromal form of conduct disorder (CD) and, if so, whether it is a precursor or prodrome syndrome of CD. METHOD: Assessments from multiple domains were used to examine 140 children with ADHD and 120 normal controls at baseline and 4 years later. RESULTS: Of children who had ADHD at baseline, 65% had comorbid ODD and 22% had CD. Among those with ODD, 32% had comorbid CD. All but one child with CD also had ODD that preceded the onset of CD by several years. ODD+CD children had more severe symptoms of ODD, more comorbid psychiatric disorders, lower Global Assessment of Functioning Scale scores, more bipolar disorder, and more abnormal Child Behavior Checklist clinical scale scores compared with ADHD children with non-CD ODD and those without ODD or CD. In addition, ODD without CD at baseline assessment in childhood did not increase the risk for CD at the 4-year follow-up, by midadolescence. CONCLUSIONS: Two subtypes of ODD associated with ADHD were identified: one that is prodromal to CD and another that is subsyndromal to CD but not likely to progress into CD in later years. These ODD subtypes have different correlates, course, and outcome.

Sleep disorders in Taiwanese children with attention deficit/hyperactivity disorder.

To assess obstructive sleep apnea syndrome (OSAS) and periodic limb movement disorder (PLMD) in children with attention deficit/hyperactivity disorder (ADHD) compared with a control group. The ADHD was diagnosed based on Diagnostic and Statistical Manual, version IV (DSM-IV) criteria on successively seen elementary school children aged 6-12 years referred to a psychiatric clinic for suspected ADHD. A standardized interview (Kiddie-SADS-E), parents and teacher questionnaires, neuropsychological testing, and nocturnal polysomnography were completed for each child. Eighty-eight children (77 boys) with ADHD and 27 controls were involved in the study. Fifty children with ADHD (56.8%) had an apnea-hypopnea index (AHI) >1 event h(-1) and 17 (19.3%) had an AHI >5 event h(-1). Nine children (10.2%) had a periodic limb movement index (PLMI) >5 events h(-1). There is one child with AHI >1 and none with a PLMI > 5 in the control group. In the test of variables of attention (TOVA), the response time was significantly worse in ADHD with sleep disorders than those without them. The child behavior checklist (CBCL) showed a significant difference between groups in the hyperactivity subscale. The diagnostic criteria for ADHD based on DSM-IV do not differentiate between children with or without sleep disorders. Evaluation of sleep disorders should be considered before starting drug treatment for ADHD.

Conduct disorder and oppositional defiant disorder in a national sample: developmental epidemiology.

BACKGROUND: Despite an expanding epidemiological evidence base, uncertainties remain over key aspects of the epidemiology of the 'antisocial' disorders in childhood and adolescence. METHODS: We used cross-sectional data on a nationally representative sample of 10,438 5-15-year-olds drawn from the 1999 British Child Mental Health Survey to examine age trends, gender ratios and patterns of comorbidity in DSM-IV Conduct Disorder (CD) and Oppositional Defiant Disorder (ODD). RESULTS: CD was significantly more common in boys than girls, and increased in prevalence with age. Among children who met diagnostic criteria for CD, status violations and other non-aggressive conduct problems increased with age, while aggressive symptoms became less common. Gender differences in ODD varied by reporter. Estimates of age trends in ODD depended heavily on treatment of overlaps with CD. Following DSM-IV guidelines (where ODD is not diagnosed in the presence of CD), rates of ODD fell with age; if that constraint was released, clinically significant rates of oppositionality persisted at similar levels from early childhood to middle adolescence. CD and ODD showed high levels of overlap, and both diagnoses showed substantial comorbidity with other non-antisocial disorders. CONCLUSIONS: Results from this large-scale study confirm and extend previous findings in the epidemiology of the disruptive behaviour disorders.

Low body weight in male children and adolescents with schizoid personality disorder or Asperger's disorder.

This study explored the hypothesis that body weight is reduced in male children and adolescents with schizoid personality disorder or Asperger's disorder. The body weights of 33 consecutively admitted male subjects with one of these disorders were retrospectively assessed with percentiles for the body mass index (BMI). The mean percentile (+/- SD) for the BMI was 31.6 +/- 27.6 and differed significantly from the expected value of 50 (P<0.001). Ten subjects had a BMI of < or = 10th age percentile. Post hoc comparisons revealed that BMI percentiles were (a) reduced to a similar extent in patients with schizoid personality disorder and Asperger's disorder and (b) reduced to a greater extent in patients with abnormal eating behaviour. During childhood and adolescence both diagnoses are associated with an increased risk of being underweight. Population-based BMI percentiles are useful for detecting associations between specific psychopathological syndromes and body weight.

Dependent personality disorder associated with phobic avoidance in patients with panic disorder.

Eighty-eight panic disorder patients were divided into three groups according to the extent of their phobic avoidance (none, limited, or extensive). These groups were compared on three personality disorder instruments: the Structured Interview for DSM-III Personality Disorders, the Personality Diagnostic Questionnaire, and the Millon Clinical Multiaxial Inventory. Phobic patients were found to have significantly more dependent personality disorder and DSM-III third-cluster personality disorders than nonphobic patients. A subgroup of patients with social phobic symptoms was found to resemble the rest of the phobic group in terms of personality.

Longitudinal course of posttraumatic stress disorder and posttraumatic stress disorder symptoms in a community sample of adolescents and young adults.

OBJECTIVE: Few studies have focused on the natural course of posttraumatic stress disorder (PTSD) and its determinants in samples of the general population. The authors examined determinants of remission and chronicity of PTSD and associations with other disorders in a prospective community sample. METHOD: The data were drawn from a prospective, longitudinal epidemiological study of adolescents and young adults (age 14-24 years) in Munich, Germany (N=2,548). The course of PTSD from baseline to follow-up 34-50 months later was studied in 125 respondents with DSM-IV PTSD or subthreshold PTSD at baseline. RESULTS: Although 52% of the PTSD cases remitted during the follow-up period, 48% showed no significant remission of PTSD symptoms. Respondents with a chronic course were more likely to experience new traumatic event(s) during follow-up (odds ratio=5.21, 95% confidence interval [CI]=1.95-13.92), to have higher rates of avoidant symptoms at baseline (odds ratio=10.16, 95% CI=1.73-59.51), and to report more help seeking (odds ratio=5.50, 95% CI=1.04-29.05), compared to respondents with remission. Rates of incident somatoform disorder (odds ratio=4.24, 95% CI=1.60-11.19) and other anxiety disorders (odds ratio=4.07, 95% CI=1.15-14.37) were also significantly associated with a chronic course. CONCLUSIONS: PTSD is often a persistent and chronic disorder. Specific symptom clusters--especially avoidant symptoms--might be associated with the course of PTSD. In addition, the occurrence of new traumatic events differentiates PTSD cases with a chronic course from those with remission.

Clinical impact of obsessive-compulsive disorder comorbidity in bipolar disorder: a systematic review and meta-analysis.

BACKGROUND: Bipolar disorder (BD) is commonly comorbid with other psychiatric conditions, such as obsessive-compulsive disorder (OCD). Despite increasing interest in this comorbidity, quantitative data on its clinical characteristics remain limited. This systematic review and meta-analysis aimed to evaluate the clinical impact of OCD comorbidity in BD by comparing individuals with BD and OCD (BD-OCD) to those with BD without OCD. METHODS: We systematically searched the PubMed/MEDLINE, Scopus, PsycINFO, and Web of Science databases up to April 15, 2024. Meta-analyses were conducted to compare BD-OCD and BD without OCD groups across multiple clinical domains. RESULTS: From 11,959 initial records screened, 26 studies were included in the qualitative synthesis, with 22 eligible for meta-analysis. Individuals with BD-OCD showed higher odds of experiencing chronic mood episodes (OR = 9.42; 95%CI = 2.23, 39.9), rapid cycling (OR = 1.92; 95%CI = 1.04, 3.53), comorbid eating disorders (OR = 3.37; 95%CI = 1.99, 5.7), panic disorder (OR = 3.3; 95%CI = 2.11, 5.2), substance use disorders (OR = 1.39; 95%CI = 1.02, 1.89), and lifetime suicide attempts (OR = 1.85; 95%CI = 1.21, 2.84). Additionally, they presented earlier onset of BD (SMD = -0.27; 95%CI = -0.52, -0.01) and reduced functioning (SMD = -0.42; 95%CI = -0.59, -0.24). Most data were derived from adult populations, limiting the evidence available for children and adolescents. CONCLUSIONS: BD-OCD presents a more severe and complex clinical profile, requiring specialized assessment and integrated treatment approaches. Identifying these features may support earlier recognition and inform personalized interventions for this population.

Association of antisocial personality disorder with psychiatric morbidity among patients with substance use disorder.

OBJECTIVES: The aims were to determine among patients with Substance Use Disorder (SUD) whether patients with Antisocial Personality Disorder (ASPD) manifest less, the same, or more of the following: (1) psychiatric symptoms, (2) family history of psychiatric disorder, (3) psychiatric disorders and morbidity, and (4) psychiatric treatment, as compared to patients without ASPD. DESIGN & DEFINITION: Scheduled interview using DSM-III-R criteria for ASPD, with blinded interviewers making the ASPD classification vs. other assessments. SETTINGS: Alcohol-drug treatment programs located in two university medical centers. SUBJECTS: Six hundred and six voluntary patients aged 18 and older meeting diagnostic criteria for SUD. RESULTS: SUD patients with ASPD reported more family history of non-SUD psychiatric diagnoses and endorsed more hostility symptoms. Demographic characteristics, psychiatric disorder, and past psychiatric treatment did not differ in association with ASPD.

Psychotic subtyping of major depressive disorder and posttraumatic stress disorder.

BACKGROUND: Many studies have established that a large percentage of patients with posttraumatic stress disorder (PTSD) have comorbid major depressive disorder. Other studies have found that patients with PTSD or a history of childhood trauma have an increased rate of psychotic symptoms. In the present report from the Rhode Island Methods to Improve Diagnosis and Services project, we examine whether an association exists between psychotic subtyping of major depressive disorder and PTSD. METHOD: Five hundred psychiatric outpatients were interviewed with the Structured Clinical Interview for DSM-IV. RESULTS: Almost half of the 500 patients had nonbipolar major depressive disorder (N = 235, 47.0%), 45 (19.1%) of whom had PTSD. Nineteen patients had psychotic depression, 216 had nonpsychotic depression. Compared with patients with nonpsychotic depression, the patients with psychotic depression were nearly 4 times more likely to have PTSD (57.9% vs. 15.7%, Fisher exact test, p = .0001). CONCLUSION: The results of the present study suggest that the presence of psychosis in psychiatric outpatients with major depressive disorder is associated with concurrent PTSD. It is hypothesized that the poorer longitudinal course of psychotic versus nonpsychotic depression may be due to the underrecognition of PTSD in psychotically depressed patients.

[High functioning pervasive developmental disorder: coexistence with other clinical disorders].

We examined 50 children in high functioning pervasive developmental disorder (HFPDD) to study the comorbidity with other clinical disorders by questionnaires. Seventy-two percentage of them met the criteria for attention deficit hyperactivity disorder (AD/HD). The majority of the children had intelligence quotient less than 90. Learning problems, motor control problems, abnormal responses to sensory stimuli and anxiety disorder frequently coexisted in the children. Since clinical symptoms of HFPDD so diverse, it is possible that some children with HFPDD may be overlooked and diagnosed as having its coexisting disorders.

An independent analysis of the Copenhagen sample of the Danish adoption study of schizophrenia. III. The relationship between paranoid psychosis (delusional disorder) and the schizophrenia spectrum disorders.

To genetic relationship between paranoid psychosis (delusional disorder) and schizophrenia spectrum disorders (schizophrenia and schizotypal personality disorder) is examined by a blind independent diagnostic evaluation of the interviews of relatives from the greater Copenhagen sample of the Danish Adoption Study of Schizophrenia. While cases of schizophrenia spectrum disorders are strongly concentrated in the biologic relatives of the schizophrenic adoptees, this pattern is not found for delusional disorder. These results suggest that from a genetic perspective, delusional disorder is not part of the schizophrenia spectrum.
