Association of bipolar and substance use disorders in parents of adolescents with bipolar disorder.

BACKGROUND: We have previously shown that juvenile bipolar disorder (BPD) is a risk for substance use disorders (SUD). Here we examine the expression of both disorders in families of youth with BPD to evaluate the familial risk mechanism. METHODS: We studied 108 adolescent BPD probands with 187 parents (34 with SUD and 58 parents) and 96 control probands with 177 parents with structured interviews. We compared the prevalence of BPD and SUD with Cox proportional hazards models with time to onset of BPD or SUD as the dependent variable and proband diagnosis (Control, BPD, or BPD+SUD) as the independent variable. RESULTS: The parents of the proband youth with BPD (without SUD) and BPD+SUD were more likely to develop BPD than the parents of control subjects [omnibus test chi2=10.18, p=.006]; we found no differences between the two bipolar groups. Parents of proband youth with BPD and with BPD+SUD were more likely than relatives of control subjects to develop SUD [omnibus test chi2=14.69, p<.001]; however, we found no differences between the parents of the two proband bipolar groups. Within the parents of proband youth with BPD+SUD, we found higher risk of SUD in parents with BPD than in those without BPD [chi2=8.39, p=.004], although the frequency of BPD was low in this group of parents. CONCLUSIONS: Bipolar disorder and SUD are prevalent in the first-degree relatives of adolescents with BPD. Adults with BPD were more likely to manifest SUD with preliminary evidence of BPD and SUD cosegregation.     

Risk of substance use disorders in adolescents with bipolar disorder

OBJECTIVE: Previous work in adults and youths has suggested that juvenile onset bipolar disorder (BPD) is associated with an elevated risk of substance use disorders (SUD). Considering the public health importance of this issue, the authors now report on a controlled study of adolescents with and without BPD to evaluate the risk of SUD. METHOD: Probands with DSM-IV BPD (n=57, mean age +/- SD=13.3 +/- 2.4 years) and without DSM-IV BPD (n=46, 13.6 +/- 2.2 years) were studied. Structured psychiatric interviews and multiple measures of SUD were collected. RESULTS: Bipolar disorder was associated with a highly significant risk factor for SUD (32% versus 7%, Z=2.9, p=.004) that was not accounted for by conduct disorder (adjusted odds ratio=5.4, p=.018). Adolescent-onset BPD (> or =13 years) was associated with a higher risk of SUD compared with those with child-onset BPD (chi1=9.3, p=.002). CONCLUSIONS: These findings strongly indicate that BPD, especially adolescent onset, is a significant risk factor for SUD independently of conduct disorder.     

Post-traumatic stress disorder among adolescents with bipolar disorder and its relationship to suicidality

OBJECTIVES: The aims of this cross-sectional pilot study were to ascertain the rates of post-traumatic stress disorder (PTSD) among adolescents with bipolar disorder (BPD) and major depressive disorder (MDD) relative to a comparison group comprised of non-affectively ill patients, and to determine whether PTSD is related to suicidal ideation and attempts. The impetus for the study was born of clinical impressions derived in the course of routine clinical practice. METHODS: Patients were screened by a single interviewer for BPD, MDD and PTSD, panic disorder, obsessive-compulsive disorder (OCD) and social phobia using the apposite modules from the Structured Clinical Interview for DSM-IV (SCID) and histories of suicidal ideation and attempts. The data were subjected to analysis using a logistic regression model. RESULTS: The database included 34 patients with BPD, 79 with MDD and 26 with a non-affective disorder. The risk for PTSD for a patient with BPD significantly exceeded that for a patient with MDD [odds ratio (OR) = 4.9, 95% confidence interval (CI) = 1.9-12.2, p = 0.001]. Patients with PTSD had an insignificantly increased risk for suicidal ideation (OR = 2.8, 95% CI = 0.9-8.9, p = 0.069), and a 4.5-fold significantly increased risk of having had a suicide attempt (OR = 4.5, 95% CI = 1.7-11.7, p = 0.002). The relationship between PTSD and suicide attempts remained significant even after controlling for the confounding effects of concurrent panic disorder, OCD and social phobia (OR = 3.4, 95% CI = 1.1-10.0, p = 0.023). CONCLUSIONS: Patients with BPD have a greater risk for PTSD than those with MDD. Post-traumatic stress disorder is significantly related to history of suicide attempts.     

Comorbidity of borderline personality disorder and posttraumatic stress disorder in the U.S. population

While placed on different axes of the DSM classification system, borderline personality disorder (BPD) and posttraumatic stress disorder (PTSD) have important relationships with trauma, and overlap between these disorders has long been recognized. The current study is the first to examine comorbidity of PTSD and BPD in a large nationally representative sample using a reliable and valid method of assessing Axis I and II mental disorders. Data came from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) Wave II (N = 34,653; response rate 70.2%). Multiple regression models were used to examine differences in psychopathology, traumatic events and health-related quality of life across individuals with PTSD alone (n = 1820), BPD alone (n = 1290) and those with comorbid PTSD–BPD (n = 643). The lifetime prevalence of PTSD and BPD were 6.6% and 5.9%, respectively. Of individuals with BPD, 30.2% were also diagnosed with PTSD, whereas 24.2% of individuals with PTSD were also diagnosed with BPD. Individuals with comorbid PTSD–BPD had a poorer quality of life, more comorbidity with other Axis I conditions, increased odds of a lifetime suicide attempt, and a higher prevalence of repeated childhood traumatic events than individuals with either condition alone. These results show that PTSD and BPD have a high degree of lifetime co-occurrence but are not entirely overlapping. Their concurrence is associated with poorer functioning compared to either diagnosis alone, emphasizing the clinical utility of diagnosing both conditions. Future research should explore the determinants of having either or both diagnoses with an aim toward improved identification, prevention, and intervention.     

Risk for substance use disorders in youths with child- and adolescent-onset bipolar disorder.

OBJECTIVE: Previous work in adults has suggested that early-onset bipolar disorder (BPD) is associated with an elevated risk for substance use disorders (SUD). To this end, the authors assessed the risk for SUD in child- versus adolescent-onset BPD with attention to comorbid psychopathology. METHOD: All youths (aged 13-18 years) with available structured psychiatric interviews were studied systematically. From clinic subjects (N = 333), 86 subjects with DSM-III-R BPD were identified. To evaluate the risk for SUD and BPD while attending to developmental issues, the authors stratified the BPD sample into those with child-onset BPD (< or = 12 years of age, n = 50) and those with adolescent-onset BPD (13-18 years of age, n = 36). RESULTS: In mid-adolescence, youths with adolescent-onset BPD were at significantly increased risk for SUD relative to those with child-onset BPD (39% versus 8%; p = .001). Compared with those with child-onset BPD, those with adolescent-onset BPD had 8.8 times the risk for SUD (95% confidence interval = 2.2-34.7; chi 7(2) = 9.7, p = .002). The presence of conduct disorder or other comorbid psychopathology within BPD did not account for the risk for SUD. CONCLUSIONS: Adolescent-onset BPD is associated with a much higher risk for SUD than child-onset BPD, which was not accounted for by conduct disorder or other comorbid psychopathology. Youths with adolescent-onset BPD should be monitored and educated about SUD risk. The identification and treatment of manic symptomatology may offer therapeutic opportunities to decrease the risk for SUD in these high-risk youths.

Bipolar Disord 2010: 12: 185–195.
© 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objective: To explore bidirectional comorbidity between bipolar disorder (BPD) and obsessive‐compulsive disorder (OCD) in youth and to examine the symptom profile and clinical correlates of both disorders in the context of reciprocal comorbidity and ascertainment status. Methods: Two samples of consecutively referred youth (ages 6–17 years) ascertained contemporaneously for respective studies of BPD and OCD were compared using clinical and scalar assessment and structured diagnostic interviews. Results: A total of 21% (17/82) of the BPD subjects and 15% (19/125) of the OCD subjects met DSM‐III‐R diagnostic criteria for both disorders. In the presence of BPD, youth with OCD more frequently experienced hoarding/saving obsessions and compulsions along with a clinical profile of greater comorbidity, poorer global functioning, and higher rate of hospitalization that is characteristic of BPD. Multiple anxiety disorders (≥ 3), especially generalized anxiety disorder and social phobia, were present at a higher frequency when OCD and BPD were comorbid than otherwise. In subjects with comorbid OCD and BPD, the primary disorder of ascertainment was associated with an earlier onset and more severe impairment. Conclusions: An unexpectedly high rate of comorbidity between BPD and OCD was observed in youth irrespective of primary ascertainment diagnosis. In youth with comorbid OCD and BPD, the clinical characteristics of each disorder run true and are analogues to their clinical presentation in youth without reciprocal comorbidity, with the exception of increased risk for obsessions and compulsions of hoarding/saving and comorbidity with other anxiety disorders.     

The 10-year course of PTSD in borderline patients and axis II comparison subjects

Zanarini MC, Hörz S, Frankenburg FR, Weingeroff J, Reich DB, Fitzmaurice G. The 10‐year course of PTSD in borderline patients and axis II comparison subjects. Objective: The first objective is to detail the prevalence of post‐traumatic stress disorder (PTSD) over a decade of follow‐up for those in both study groups. The second is to determine time‐to‐remission, recurrence, and new onset of PTSD, and the third is to assess the relationship between sexual adversity and the likelihood of remission and recurrence of PTSD. Method: The SCID I was administered to 290 borderline in‐patients and 72 axis II comparison subjects during their index admission and re‐administered at five contiguous 2‐year follow‐up periods. Results: The prevalence of PTSD declined significantly over time for patients with borderline personality (BPD) (61%). Over 85% of borderline patients meeting criteria for PTSD at baseline experienced a remission by the time of the 10‐year follow‐up. Recurrences (40%) and new onsets (27%) were less common. A childhood history of sexual abuse significantly decreased the likelihood of remission from PTSD, and an adult history of sexual assault significantly increased the likelihood of a recurrence of PTSD. Conclusion: Taken together, the results of this study suggest that PTSD is not a chronic disorder for the majority of borderline patients. They also suggest a strong relationship between sexual adversity and the course of PTSD among patients with BPD.     

Affect intensity and lability: the role of posttraumatic stress disorder symptoms in borderline personality disorder

Background: Emotion dysregulation is likely a core psychological process underlying the heterogeneity of presentations in borderline personality disorder (BPD) and is associated with BPD symptom severity. Emotion dysregulation has also been independently associated with posttraumatic stress disorder (PTSD), a disorder that has been found to co‐occur with BPD in 30.2% of cases in a nationally representative sample. However, relatively little is known about the specific relationships between emotion dysregulation and PTSD among those diagnosed with BPD. The purpose of this study was to evaluate relationships between PTSD symptom severity and negative affect intensity and affective lability among individuals with BPD. Method: Participants were 67 individuals diagnosed with BPD (79% women; M _age = 38, SD = 10), who reported one or more DSM‐IV PTSD Criterion A events. Results: Hierarchical multiple regression analyses indicated that when examined concurrently with BPD symptom severity, PTSD symptom severity, but not BPD symptom severity, was related to negative affect intensity and affective lability. Re‐experiencing symptoms uniquely predicted affective lability, and hyperarousal symptoms uniquely predicted negative affect intensity, lending additional support to emerging literature linking re‐experiencing and hyperarousal symptoms with emotion dysregulation. Conclusions: PTSD symptom severity among individuals with a BPD diagnosis is related to elevations in emotion dysregulation. It is important to evaluate whether early treatment of PTSD symptoms provided concurrently with BPD treatment leads to enhanced improvements in emotion regulation among individuals with co‐occurring PTSD and BPD.

Examining the nature of the comorbidity between pediatric attention deficit/hyperactivity disorder and post‐traumatic stress disorder

Biederman J, Petty CR, Spencer TJ, Woodworth KY, Bhide P, Zhu J, Faraone SV. Examining the nature of the comorbidity between pediatric attention deficit/hyperactivity disorder and post‐traumatic stress disorder. Objective: This study sought to address the link between attention deficit/hyperactivity disorder (ADHD) and post‐traumatic stress disorder (PTSD) in youth by providing a comprehensive comparison of clinical correlates of ADHD subjects with and without PTSD across multiple non‐overlapping domains of functioning and familial patterns of transmission. Method: Participants were 271 youths with ADHD and 230 controls without ADHD of both sexes along with their siblings. Participants completed a large battery of measures designed to assess psychiatric comorbidity, psychosocial, educational, and cognitive parameters. Results: Post‐traumatic stress disorder was significantly higher in ADHD probands vs. controls (5.2% vs. 1.7%, χ²₍₁₎ = 4.36, P = 0.04). Irrespective of the comorbidity with PTSD, ADHD subjects had similar ages at onset of ADHD, similar type and mean number of ADHD symptoms, and similar ADHD‐associated impairments. PTSD in ADHD probands was significantly associated with a higher risk of psychiatric hospitalization, school impairment, poorer social functioning and higher prevalences of mood, conduct disorder, and anxiety disorders. The mean onset of PTSD (12.6 years) was significantly later than that of ADHD and comorbid disorders (all P < 0.05). Siblings of ADHD and ADHD + PTSD probands had higher prevalences of ADHD vs. siblings of controls (35% vs. 18%, z = 4.00, P < 0.001 and 67% vs. 18%, z = 4.02, P < 0.001 respectively) and siblings of ADHD+PTSD probands had a significantly higher prevalence of PTSD compared with the siblings of ADHD and control probands (20% vs. 3% and 3%, z = 2.99, P = 0.003 and z = 2.07, P = 0.04 respectively). Conclusion: Findings indicate that the comorbidity with PTSD in ADHD leads to greater clinical severity as regards psychiatric comorbidity and psychosocial dysfunction. ADHD is equally familial in the presence of PTSD in the proband indicating that their co‐occurrence is not owing to diagnostic error.     

The spectrum of substance abuse in bipolar disorder: reasons for use, sensation seeking and substance sensitivity

OBJECTIVES: To examine the spectrum of alcohol and substance abuse, including reasons for use, in patients with bipolar I disorder, compared with patients with substance use disorder and healthy controls, with a specific focus on the relationship between substance use, substance sensitivity, other comorbid psychiatric symptoms and traits related to sensation seeking. METHODS: This study included 104 patients with bipolar I disorder (BPD I), of whom 57 (54.8%) met DSM-IV criteria for lifetime alcohol or substance use disorder (BPD + SUD), 35 patients with substance use disorder (SUD) and no psychiatric disorder and 50 healthy controls. Assessments included the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) and the Structured Clinical Interview for the Spectrum of Substance Use (SCI-SUBS). RESULTS: Patients with BPD + SUD and SUD had significantly higher scores on the SCI-SUBS domains of self-medication, substance sensitivity and sensation seeking compared with patients with BPD and healthy controls. Reasons for substance use did not differ between patients with BPD + SUD and patients with SUD. Those most frequently cited were: improving mood; relieving tension; alleviating boredom; achieving/maintaining euphoria; and increasing energy. CONCLUSIONS: Recourse to substances is associated with increased mood and anxiety symptoms, substance sensitivity, and sensation seeking among patients with BPD + SUD and SUD. Substance sensitivity and sensation seeking traits should be investigated in all patients with BPD as possible factors associated with a development of SUD, in order to warn patients of the specific risks related to improper use of medications and substances.     

Substance use disorders among adolescents with bipolar spectrum disorders

Objective: We set out to examine the prevalence and correlates of substance use disorders (SUD) in a large sample of adolescents with bipolar disorder (BP). Methods: Subjects were 249 adolescents ages 12 to 17 years old who fulfilled DSM‐IV criteria for bipolar I disorder [(BPI), n = 154], or bipolar II disorder [(BPII), n = 25], or operationalized criteria for BP not otherwise specified [(BP NOS), n = 70], via the Schedule for Affective Disorders and Schizophrenia for School‐Aged Children (K‐SADS). As part of the multi‐site Course and Outcome of Bipolar Youth study, demographic, clinical, and family history variables were measured via intake clinical interview with the subject and a parent/guardian. Results: The lifetime prevalence of SUD among adolescents with BP was 16% (40/249). Results from univariate analyses indicated that subjects with, as compared to without, SUD were significantly less likely to be living with both biological parents, and that there was significantly greater lifetime prevalence of physical abuse, sexual abuse, suicide attempts, conduct disorder, and posttraumatic stress disorder among subjects with SUD. Subjects with SUD reported significantly greater 12‐month prevalence of trouble with police, and females with SUD reported significantly greater 12‐month prevalence of pregnancy and abortion. Significant predictors of SUD in a logistic regression model included living with both biological parents (lower prevalence), conduct disorder and suicide attempts (increased prevalence). In logistic regression analyses controlling for demographic differences and conduct disorder, SUD remained significantly associated with trouble with police, whereas the association of SUD with pregnancy and abortion was reduced to a statistical trend. The prevalence of SUD was not significantly different among child‐ versus adolescent‐onset BP subjects. Conclusions: SUD among adolescents with BP is associated with profound hazards including suicide attempts, trouble with police, and teenage pregnancy and abortion.     

Response to second generation antipsychotics in youth with comorbid bipolar disorder and autism spectrum disorder

Objective: To assess the impact of comorbid autism spectrum disorders (ASD) on the response to second‐generation antipsychotics (SGA) in pediatric bipolar disorder (BPD). Methods: Secondary analysis of identically designed 8‐week open‐label trials of SGA monotherapy (risperidone, olanzapine, quetiapine, ziprasidone, or aripiprazole) in youth with BPD. Results: Of the 151 BPD subjects 15% (n= 23) met criteria for comorbid ASD. There were no differences in the rate of antimanic response (YMRS change ≥30% or CGI‐Improvement ≤2: 65% vs. 69%; P= 0.7) in the presence of comorbid ASD. Conclusion: No difference observed in the rate of antimanic response or tolerability to SGA monotherapy in the presence of ASD comorbidity.     

Impact of behavioral/developmental disorders comorbid with conduct disorder

Aims: The aim of the present study was to verify the comorbidity of conduct disorder (CD) and behavioral/developmental disorders in children and adolescents, and to examine the traits of CD comorbid with them. Methods: Subjects were 64 children (60 boys, four girls) who were resident at three institutions for delinquent children or who were conduct‐disordered outpatients of a university hospital aged under 18 years. A diagnostic interview was carried out by experienced child psychiatrists and the intelligence score and the Adverse Childhood Experiences score were measured by a licensed psychologist. Results: A total of 57 children were diagnosed as having CD, of whom 26 (45.6%) were diagnosed with comorbid attention‐deficit–hyperactivity disorder (ADHD), 12 were diagnosed with comorbid pervasive developmental disorder (PDD, 21,1%), and 19 (33.3%) had no comorbidity of either disorder. Six children (18.8% of CD comorbid with ADHD) met the criteria for both ADHD and PDD. The group with comorbid PDD was significantly younger at onset (F = 6.51, P = 0.003) and included unsocialized type more frequently (χ² = 6.66, P = 0.036) compared with the other two groups. Conclusions: Clinicians should be aware that not only ADHD but also PDD may be comorbid with CD. Establishment of the correct diagnosis is important because recognizing the presence of PDD will enable us to provide appropriate treatment and guidance, which may improve prognosis.     

Psychiatric comorbidity associated with co-occurring autism spectrum disorder and substance use disorder

BackgroundAlthough both autism spectrum disorder (ASD) and substance use disorder (SUD) are both commonly comorbid with other psychiatric conditions, there is a paucity of research on the overlap of these disorders. The primary aim of the present study was to identify the prevalence of psychiatric comorbidities in young adults with SUD and ASD compared to those with ASD only.MethodMultivariate logistic regression controlling for age was used to compare the prevalence of psychiatric disorders in a sample of treatment-seeking adult outpatients with a) ASD without SUD and b) ASD with SUD. Psychiatric and SUD diagnoses were determined by semi-structured interview (SCID for DSM IV).ResultsThe sample included 42 patients with ASD only (mean age ± SD = 26.2 ± 8.9 years) and 21 with ASD and SUD (35.2 ± 12.6). High rates of psychopathology were found in both groups. Comorbid conduct disorder (CD) was significantly more prevalent in the ASD + SUD group (25 %) compared to those without SUD (5%; p < 0.05). There were no other significant differences between groups in the rates of non-conduct comorbid psychopathology.ConclusionIn both groups, rates of psychopathology were high with CD being significantly more common in young adults with ASD and SUD. These findings highlight the importance of screening for CD in individuals with ASD to mitigate the potential development of comorbid SUD. Further research is needed to determine if CD is a true risk factor for SUD in the ASD population and identify other risk factors.     

Age at onset in 3014 Sardinian bipolar and major depressive disorder patients

Tondo L, Lepri B, Cruz N, Baldessarini RJ. Age at onset in 3014 Sardinian bipolar and major depressive disorder patients. Objective: To test if onset age in major affective illnesses is younger in bipolar disorder (BPD) than unipolar‐major depressive disorder (UP‐MDD), and is a useful measure. Method: We evaluated onset‐age for DSM‐IV‐TR major illnesses in 3014 adults (18.5% BP‐I, 12.5% BP‐II, 69.0% UP‐MDD; 64% women) at a mood‐disorders center. Results: Median and interquartile range (IQR) onset‐age ranked: BP‐I = 24 (19–32) < BP‐II = 29 (20–40) < UP‐MDD = 32 (23–47) years (P < 0.0001), and has remained stable since the 1970s. In BP‐I patients, onset was latest for hypomania, and depression presented earlier than in BP‐II or UP‐MDD cases. Factors associated with younger onset included: i) being unmarried, ii) more education, iii) BPD‐diagnosis, iv) family‐history, v) being employed, vi) ever‐suicidal, vii) substance‐abuse and viii) ever‐hospitalized. Onset‐age distinguished BP‐I from UP‐MDD depressive onsets with weak sensitivity and specificity. Conclusion: Onset age was younger among BPD than MDD patients, and very early onset may distinguish BPD vs. UP‐MDD with depressive‐onset.     

Aggression and substance abuse in bipolar disorder

Objectives:  The goal of this retrospective study was to examine factors differentiating persons with bipolar disorder who did or did not have comorbid lifetime substance use disorders (SUD) at an index assessment. We also explored the chronology of onset of mood and SUD.
Methods:  We studied 146 subjects with DSM-defined bipolar disorder. Subgroups with and without lifetime SUD were compared on demographic and clinical measures.
Results:  Substance abuse disorders in this bipolar sample were associated with male sex, impulsive-aggressive traits, comorbid conduct and Cluster B personality disorders, number of suicide attempts and earlier age at onset of a first mood episode. In a multivariable logistic regression analysis, male sex and aggression and possibly earlier age at mood disorder onset were associated with SUD. In those with or without SUD, the first mood episode tended to be depressive and to precede the onset of SUD.
Conclusions:  In persons with bipolar disorder, an earlier age of onset and aggressive traits appear to be factors associated with later development of comorbid SUD.     

Psychiatric comorbidity in older adults with bipolar disorder

INTRODUCTION: Comorbidity patterns and correlates among older adults with bipolar disorder (BPD) are not well understood. The aim of this analysis was to examine the prevalence of comorbid PTSD and other anxiety disorders, substance abuse and dementia in a population of 16,330 geriatric patients with BPD in a Veterans Health Administration administrative database. METHODS: Patients were identified from case registry files during Federal Fiscal Year 2001(FY01). Comorbidity groups were compared on selected clinical characteristics, inpatient and outpatient health resource use, and costs of care. RESULTS: Four thousand six hundred and sixty-eight geriatric veterans with BPD were comorbid for either substance abuse, PTSD and other anxiety disorder, or dementia (28.6% of all veterans with BPD age 60 or older). Mean age of all veterans in the four comorbidity groups was 70.0 years (+/-SD 7.2 years). Substance abuse was seen in 1,460 (8.9%) of elderly veterans with BPD, while PTSD was seen in 875 (5.4%), other anxiety disorders in 1592 (9.7%), and dementia in 741 (4.5%) of elderly veterans. Individuals with substance abuse in this elderly bipolar population are more likely to be younger, minority, unmarried and homeless compared to elderly bipolar populations with anxiety disorders or dementia. Inpatient use was greatest among geriatric veterans with BPD and dementia compared to veterans with BPD and other comorbid conditions. CONCLUSION: Clinical characteristics, health resource use and healthcare costs differ among geriatric patients with BPD and comorbid anxiety, substance abuse or dementia. Additional research is needed to better understand presentation of illness and modifiable factors that may influence outcomes.     

Obstetrical complications in children at high risk for bipolar disorder

OBJECTIVE: To examine obstetrical complications as a risk factor for developing bipolar disorder (BPD). We hypothesized that children with a bipolar parent would be at greater risk for obstetrical complications than demographically matched children of healthy adults. Additionally, within this "at-risk" (AR) sample, we hypothesized that obstetrical complications would be associated with the development of psychiatric disorders. METHODS: The Washington University in St. Louis Kiddie-Schedule for Affective Disorders and Schizophrenia (WASH-U KSADS) was administered to children (AR) who had at least one parent with BPD (N=36) and children of healthy parents (HC) (N=27), by raters who were blind to diagnostic category. To assess obstetrical risk history, the Rochester Research Obstetrical Scale (ROS) was administered to parents of AR and HC children. RESULTS: Children at familial risk for BPD had greater total (p=0.02) and prenatal (p=0.006) obstetrical complication scores than children of healthy parents. However, obstetrical complications were not associated with the development of affective, anxiety, or disruptive behavioral disorders within the at-risk group. CONCLUSION: Our data suggest that compared with children of families without BPD, children of parents with BPD may be at greater risk for obstetrical complications, particularly those that occur during the prenatal period; however, at this early follow-up period factors other than obstetrical complications appear to contribute to the differences in rates of psychiatric disorders between these groups.     

Substance use disorders in an obsessive compulsive disorder clinical sample

The prevalence and clinical correlates of substance use disorders (SUDs) were examined in a clinical sample of Obsessive Compulsive Disorder (OCD). As part of their intake interview into an observational study of the course of OCD, 323 participants completed a battery of standardized measures. Twenty-seven percent of the sample met lifetime criteria for a SUD. 70% of participants with comorbid SUDs reported that OCD preceded SUD onset by at least one year. Younger age at OCD onset and presence of Borderline Personality Disorder (BPD) were each associated with increased risk of alcohol use disorders but only BPD was associated with increased risk of drug use disorders. SUDs affect more than one-quarter of individuals who seek treatment for OCD. Individuals with a juvenile-onset of OCD or comorbid BPD may be especially vulnerable to SUDs. Further research is needed to identify risk factors for SUDs and to better understand their impact on OCD course.     

Implementation and clinical characteristics of a posttraumatic stress disorder brain collection

A postmortem human brain collection to study posttraumatic stress disorder (PTSD) is critical for uncovering the molecular mechanisms that contribute to this psychiatric disorder. We describe here the PTSD brain collection at the Lieber Institute for Brain Development in Baltimore, Maryland, consisting of postmortem brain donations acquired between 2012 and 2017. Thus far, 87 brains from individuals meeting DSM‐5 criteria for PTSD were collected after consent was obtained from legal next‐of‐kin, and subsequently clinically characterized for molecular studies. PTSD brain donors had high rates of comorbid diagnoses, including depression (62.1%), substance abuse (74.7%), drug‐related death (69.0%), and suicide completion (17.2%). PTSD cases were subdivided into two categories: combat‐related PTSD (n = 24) and noncombat/domestic PTSD (n = 63). The major differences between the combat‐related and domestic PTSD cohorts were sex, drug‐related death, and the prevalence of bipolar disorder (BPD) comorbidity. The combat‐related group was entirely male, with only one BPD subject (4.2%), and had significantly fewer drug‐related deaths (45.8%) in contrast to the domestic group (31.8% male, 36.5% bipolar, and 77.8% drug‐related deaths). Medical examiners' offices, particularly in areas with higher military populations, are an excellent source for PTSD brain donations of both combat‐related and domestic PTSD.
