Emergent suicidality in a clinical psychotherapy trial for adolescent depression.

OBJECTIVE: The authors' goal was to examine the incidence and predictors of emergent suicidality that occurred during a clinical trial of psychotherapy for adolescent depression. METHOD: The rates and predictors of emergent suicidality in 88 medication-free depressed adolescent outpatients who reported no current suicidality during an intake interview were assessed over 12 to 16 weeks of psychotherapy treatment. RESULTS: The incidence of emergent suicidality was 12.5% (11 of 88 subjects). Self-reported suicidal thoughts at intake were a significant predictor of emergent suicidality, even when suicidality was denied at intake interview. CONCLUSIONS: Emergent suicidality is a common occurrence in psychosocial treatment of adolescent depression, with rates similar to those reported recently in antidepressant trials. To evaluate accurately the role of treatment in emergent suicidality, it is important to assess self-reported suicidality at intake and to balance treatment groups on this key predictor of emergent suicidality.

Posttraumatic stress disorder comorbid with major depression: factors mediating the association with suicidal behavior.

OBJECTIVE: The purpose of the study was to determine if patients with a history of major depressive episode and comorbid posttraumatic stress disorder (PTSD) have a higher risk for suicide attempt and differ in other measures of suicidal behavior, compared to patients with major depressive episode but no PTSD. In addition, to explore how PTSD comorbidity might increase risk for suicidal behavior in major depressive episode, the authors investigated the relationship between PTSD, cluster B personality disorder, childhood sexual or physical abuse, and aggression/impulsivity. METHOD: The subjects were 230 patients with a lifetime history of major depressive episode; 59 also had lifetime comorbid PTSD. The demographic and clinical characteristics of subjects with and without PTSD were compared. Multivariate analysis was used to examine the relationship between suicidal behavior and lifetime history of PTSD, with adjustment for clinical factors known to be associated with suicidal behavior. RESULTS: Patients with a lifetime history of PTSD were significantly more likely to have made a suicide attempt. The groups did not differ with respect to suicidal ideation or intent, number of attempts made, or maximum lethality of attempts. The PTSD group had higher objective depression, impulsivity, and hostility scores; had a higher rate of comorbid cluster B personality disorder; and were more likely to report a childhood history of abuse. However, cluster B personality disorder was the only independent variable related to lifetime suicide attempts in a multiple regression model. CONCLUSIONS: PTSD is frequently comorbid with major depressive episode, and their co-occurrence enhances the risk for suicidal behavior. A higher rate of comorbid cluster B personality disorder appears to be a salient factor contributing to greater risk for suicidal acts in patients with a history of major depressive episode who also have PTSD, compared to those with major depressive episode alone.

Platelet serotonin reuptake inhibition and response to SSRIs in depressed adolescents.

OBJECTIVE: The authors examined platelet serotonin reuptake inhibition and response to selective serotonin reuptake inhibitor (SSRI) treatment in depressed adolescents. METHOD: Twenty-three depressed adolescents participating in pharmacokinetic studies of SSRIs had platelet serotonin reuptake measured before and after 14-28 days of treatment. The Clinical Global Impression (CGI) improvement rating was determined on the basis of all clinical information and was performed blind to the platelet data. RESULTS: Improvement in depressive symptoms as rated with the CGI improvement subscale was significantly associated with the percentage change in platelet serotonin reuptake inhibition from pre- to posttreatment. Improvement in depression was also associated with absolute decrease in platelet serotonin reuptake when adjusted for the magnitude of baseline reuptake. CONCLUSIONS: Platelet serotonin reuptake inhibition may be an appropriate surrogate biological marker for the pharmacodynamic activity of SSRIs in depressed adolescents.

Cingulate cortex anatomical abnormalities in children and adolescents with bipolar disorder.

OBJECTIVE: In vivo imaging studies have suggested anatomical and functional abnormalities in the anterior cingulate in adults with mood disorders. This anatomical magnetic resonance imaging study examined the cingulate cortex in children and adolescents with bipolar disorder and matched healthy comparison subjects. METHOD: Sixteen patients (mean age=15.5 years, SD=3.4) with DSM-IV bipolar disorder and 21 matched healthy comparison subjects (mean age=16.9 years, SD=3.8) were studied. Three-dimensional gradient echo imaging was performed (TR=25 msec, TE=5 msec, slice thickness=1.5 mm) in a 1.5-T GE Signa magnet. Cingulate volumes were compared by using analysis of covariance, with age and intracranial volume as covariates. RESULTS: The patients with bipolar disorder had significantly smaller mean volumes relative to the healthy subjects in the left anterior cingulate (mean=2.49 cm(3 [SD=0.28] versus 3.60 cm3 [SD=0.12], respectively), left posterior cingulate (2.53 cm3 [SD=0.32] versus 2.89 cm3 [SD=0.09]), and right posterior cingulate (2.19 cm3 [SD=0.13] versus 2.28 cm3 [SD=0.08]). No significant between-group difference was found for the right anterior cingulate (2.64 cm3 [SD=0.21] versus 2.71 cm3 [SD=0.10]). CONCLUSIONS: The findings indicate smaller cingulate volumes in children and adolescents with bipolar disorder, suggesting that such abnormalities may be present early in the illness course.

Clinical differences between suicidal and nonsuicidal depressed children and adolescents.

OBJECTIVE: To examine the clinical symptoms and comorbid psychiatric disorders of depressed children and adolescents with and without clinically significant suicidal ideation. METHOD: Children and adolescents aged 7 to 17 years with current DSM-III-R major depressive disorder (MDD) (N = 135) were recruited between January 1987 and April 2002. Current MDD symptoms and lifetime comorbid psychiatric disorders were assessed using either a combination of the Schedule for Affective Disorders and Schizophrenia for School Age Children-Epidemiologic and -Present Episode versions or the -Present Lifetime version. Thirty-two percent (N = 43) of the depressed subjects were classified as suicidal (at least suicidal ideation with a plan). RESULTS: Depressed suicidal youth presented with a more severe episode (p = .001) and a poorer functional status (p = .019), were more hopeless (p = .001), and presented more frequently with insomnia (p = .011). There was an interaction between suicide x sex x pubertal status for severity of MDD (p = .013), the presence of hopelessness (p < .001), poor functional status (p = .023), and comorbidity with a lifetime history of any disruptive behavior (p = .019). Among pre-pubertal depressed males, suicidal boys had significantly increased severity of MDD (p = .025) and poorer functional status (p = .044) than non-suicidal boys. Among postpubertal depressed females, suicidal girls were more frequently hopeless (p = .008) and presented an increased severity of MDD (p = .022) and more frequent lifetime history of any disruptive behavior (p = .03) when compared with nonsuicidal girls. CONCLUSION: There appears to be a sex difference for some clinical features, particularly hopelessness, among depressed suicidal children and adolescents. Whether hopelessness is a sex-specific characteristic of depressed suicidal children and adolescents requires further study.

Cross-sectional study of abnormal amygdala development in adolescents and young adults with bipolar disorder.

BACKGROUND: In vivo imaging studies in adult bipolar patients have suggested enlargement of the amygdala. It is not known whether this abnormality is already present early in the illness course or whether it develops later in life. We conducted a morphometric MRI study to examine the size of specific temporal lobe structures in adolescents and young adults with bipolar disorder and healthy control subjects, as well as their relationship with age, to examine possible neurodevelopmental abnormalities. METHODS: Subjects included 16 DSM-IV bipolar patients (16 +/- 3 years) and 21 healthy controls (mean age +/- SD = 17 +/- 4 years). Measures of amygdala, hippocampus, temporal gray matter, temporal lobe, and intracranial volumes (ICV) were obtained. RESULTS: There was a trend to smaller left amygdala volumes in patients (mean volumes +/- SD = 1.58 +/- .42 mL) versus control subjects (1.83 +/- .4 mL; F = 3.87, df = 1,32, p = .06). Bipolar patients did not show significant differences in right or left hippocampus, temporal lobe gray matter, temporal lobe, or right amygdala volumes (analysis of covariance, age, gender, and ICV as covariates, p > .05) compared with healthy control subjects. Furthermore, there was a direct correlation between left amygdala volumes and age (r =. 50, p = .047) in patients, whereas in healthy controls there was an inverse correlation (r = -.48, p = .03). CONCLUSIONS: The direct correlation between left amygdala volumes and age in bipolar patients, not present in healthy control subjects, may reflect abnormal developmental mechanisms in bipolar disorder.

Abnormal left superior temporal gyrus volumes in children and adolescents with bipolar disorder: a magnetic resonance imaging study.

Abnormalities in left superior temporal gyrus (STG) have been reported in adult bipolar patients. However, it is not known whether such abnormalities are already present early in the course of this illness. Magnetic resonance imaging (MRI) morphometric analysis of STG was performed in 16 DSM-IV children and adolescents with bipolar disorder (mean age+/-SD 15.5+/-3.4 years) and 21 healthy controls (mean age+/-SD 16.9+/-3.8 years). Subjects underwent a 3D spoiled gradient recalled acquisition MRI examination. Using analysis of covariance with age, gender and intra-cranial brain volume as covariates, we found significantly smaller left total STG volumes in bipolar patients (12.5+/-1.5 cm(3)) compared with healthy controls (13.6+/-2.5 cm(3)) (F=4.45, d.f.=1, 32, P=0.04). This difference was accounted for by significantly smaller left and right STG white matter volumes in bipolar patients. Decreased white matter connections may be the core of abnormalities in STG, which is an important region for speech, language and communication, and could possibly underlie neurocognitive deficits present in bipolar patients.

Phenomenology of panic disorder in youth.

We compared the demographic and clinical characteristics of youth with panic disorder (PD) (n=42), non-panic anxiety (n=407), and non-anxiety psychiatric disorders (n=1,576). Subjects were recruited from a mood and anxiety disorders clinic and assessed with the KSADS-P. In this large clinical sample, approximately 2% of the patients had PD. Most of these patients were adolescent, female, and Caucasian. PD was associated frequently with comorbid bipolar disorder, MDD, and other anxiety conditions, in particular general anxiety and separation anxiety disorders. Palpitations, chest pain, faintness, and trembling/shaking were the most frequent PD symptoms. In comparison with the other groups, youths with PD were significantly slightly older, Caucasian, and have more comorbid bipolar disorder. Subjects with both panic and non-panic anxiety disorders were more likely to have comorbid major depression and conduct disorders than those with other non-anxiety disorders.

Normal pituitary volumes in children and adolescents with bipolar disorder: a magnetic resonance imaging study.

The volume of the pituitary gland in adults with bipolar disorder has previously been reported to be smaller than that of healthy controls. Such abnormalities would be consistent with the HPA dysfunction reported in this illness. We conducted a study of children and adolescents with bipolar disorder to determine whether size abnormalities in the pituitary gland are already present early in illness course. Magnetic resonance imaging (MRI) morphometric analysis of the pituitary gland was carried out in 16 DSM-IV children and adolescents with bipolar disorder (mean age+/-sd=15.5+/-3.4 years) and 21 healthy controls (mean age+/-sd=16.9+/-3.8 years). Subjects underwent a 1.5 T MRI, with 3-D Spoiled Gradient Recalled (SPGR) acquisition. There was no statistically significant difference between pituitary gland volumes of bipolar patients compared to healthy controls (ANCOVA, age, gender, and ICV as covariates; F=1.77, df=1,32, P=.19). There was a statistically significant direct relationship between age and pituitary gland volume in both groups (r=.59, df=17, P=.007 for healthy controls; r=.61, df=12, P=.008 for bipolar patients). No evidence of size abnormalities in the pituitary gland was found in child and adolescent bipolar patients, contrary to reports involving adult bipolar patients. This suggests that anatomical abnormalities in this structure may develop later in illness course as a result of continued HPA dysfunction.

A practical guide to using ratings of depression and anxiety in child psychiatric practice.

The objective of this paper is to provide pragmatic information on commonly used rating scales of depression and anxiety disorders with established psychometric properties. A comprehensive Medline search on the rating scales of depression and anxiety was conducted. Relevant research findings were further synthesized where possible, with the information on clinical use of the scales from manuals. Research findings replicating original studies, strengths, weaknesses, and scoring information were summarized for each scale, and psychometric properties were tabulated. Several rating scales are available for screening, determining the severity, as well as estimating treatment effects in depression and anxiety. It is prudent to use more than two scales, especially a combination of self-rating scale and a clinician rating scale. It is recommended that the depression and anxiety scales are used in concert to aid in differentiating these two disorders. Several new and improved scales are available, although they await further replication.

Family-focused treatment for adolescents with bipolar disorder.

BACKGROUND: Research has begun to elucidate the optimal pharmacological treatments for pediatric-onset bipolar patients, but few studies have examined the role of psychosocial interventions as adjuncts to pharmacotherapy in maintenance treatment. This article describes an adjunctive family-focused psychoeducational treatment for bipolar adolescents (FFT-A). The adult version of FFT has been shown to be effective in forestalling relapses in two randomized clinical trials involving bipolar adults. METHODS: FFT-A is administered to adolescents who have had an exacerbation of manic, depressed, or mixed symptoms within the last 3 months. It is given in 21 outpatient sessions of psychoeducation, communication enhancement training, and problem solving skills training. We describe modifications to the adult FFT model to address the developmental issues and unique clinical presentations of pediatric-onset patients. RESULTS: An open treatment trial involving 20 bipolar adolescents (11 boys, 9 girls; mean age 14.8+/-1.6) found that the combination of FFT-A and mood stabilizing medications was associated with improvements in depression symptoms, mania symptoms, and behavior problems over 1 year. LIMITATIONS: These early results are based on a small-scale open trial. CONCLUSIONS: Results from an ongoing randomized controlled trial will clarify whether combining FFT-A with pharmacotherapy improves the 2-year course of adolescent bipolar disorder. If the results are positive, then a structured manual-based psychosocial approach will be available for clinicians who treat adolescent bipolar patients in the community.

Clinical presentation and course of depression in youth: does onset in childhood differ from onset in adolescence?

OBJECTIVE: To simultaneously and prospectively compare the clinical presentation, course, and parental psychiatric history between children and adolescents with major depressive disorder. METHOD: A group of prepubertal children (n = 46) and postpubertal adolescents (n = 22) were assessed with structured interviews for psychopathology and parental psychiatric history and followed once every 2 years for approximately 5 years. RESULTS: With the exception of more depressive melancholic symptoms in the adolescents, both groups had similar depressive symptomatology, duration (average 17 months), severity of the index episode, rates of recovery (85%) and recurrence (40%), comorbid disorders, and parental psychiatric history. Female sex, increased guilt, prior episodes of depression, and parental psychopathology were associated with worse longitudinal course. CONCLUSIONS: In general, major depressive disorder is manifested similarly in children and adolescents, and both groups have a protracted clinical course and high family loading for psychiatric disorders.

First episode of depression in children at low and high familial risk for depression.

OBJECTIVE: To examine the development of first-onset major depressive disorder (MDD) in children at high and low familial risk for depression in a prospective study. METHOD: High-risk children (n = 76) who were free of any lifetime affective disorder and had at least one first-degree and one second-degree relative with a lifetime history of childhood-onset, recurrent, bipolar, or psychotic depression were included. Low-risk children (n = 63) were included if they were free of any lifetime psychiatric disorder and had no first-degree relatives and fewer than 20% of their second-degree relatives with a lifetime affective disorder. Children and their parents were assessed in a prospective design using the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Epidemiologic version (K-SADS-E). The average interval between follow-up interviews was 18 months, and the average follow-up period was 6 years. RESULTS: High-risk children had approximately a threefold increased risk of developing first-onset MDD compared with low-risk children (odds ratio = 3.21). The average age of new-onset MDD was 14.0 +/- 2.9 years (range 9.5-19.5 years). Above and beyond the familial loading for MDD, mother's lifetime anxiety disorder (odds ratio = 2.84) and lifetime behavioral disorder (odds ratio = 3.25) in the child significantly added to the risk of developing a first-onset MDD. CONCLUSIONS: Having high familial loading for affective disorders, a mother with and anxiety disorder, and a behavioral disorder in the child all significantly contributed to the risk of developing depression.

Psychosocial functioning in youths at high risk to develop major depressive disorder.

OBJECTIVE: To compare the psychosocial functioning of children and adolescents at high risk of major depressive disorder with youths with acute major depressive disorder and healthy controls. METHOD: High-risk (n = 57), major depressive disorder (n = 71), and healthy control (n = 48) youths and their families were recruited from 1987 to 1996 and assessed for psychopathology using standardized instruments. Except for 16 children who had disruptive disorders, the high-risk children were free of psychopathology. A parent completed the Psychosocial Schedule to evaluate the mother-child, father-child, marital relationships, and child-friend relationships and the child's school performance. RESULTS: Overall, high-risk and healthy controls had similar psychosocial functioning. Marital relationships were worse in the high-risk children with psychopathology. Youths with major depressive disorder had significantly more psychosocial problems and school difficulties than those at high risk and healthy controls in most domains measured. Controlling for age, pubertal stage, race, sex, family composition, current and lifetime parental depression, and current and lifetime parental nonmood psychopathology yielded similar results. CONCLUSIONS: The family and peer interactions of high-risk youths were similar to the interactions of healthy controls. Although family dysfunctional patterns seem to mainly depend on the child's depressive symptoms, longitudinal studies are needed to establish causality.

Familial transmission of mood disorders: convergence and divergence with transmission of suicidal behavior.

OBJECTIVE: Both mood disorder and suicidal behavior are familial. In this study, the authors examine the factors associated with the familial transmission of these two related conditions to learn which are shared or unique risk factors for familial transmission. METHOD: The 285 offspring of 141 probands with mood disorder were studied. Proband and offspring characteristics associated with offspring mood disorder were examined by univariate statistics, logistic and Cox regression, and path analysis. RESULTS: Parental history of sexual abuse was associated with an increased risk of offspring mood disorder. The relationship between parent sexual abuse and offspring mood disorder was mediated by offspring impulsive aggression, sexual abuse, and anxiety disorder. In offspring, higher levels of impulsive aggression were associated with earlier age at onset of mood disorder. Offspring suicide attempt was mainly related to offspring mood disorder, with additional contributions from offspring sexual abuse and impulsive aggression. CONCLUSIONS: The pathways associated with the familial transmission of mood disorder and of suicide attempt are similar but not identical. Prevention of early-onset mood disorder by targeting high- risk families may help to prevent the transmission of suicidal behavior. Because these data are cross-sectional, these results must be confirmed by prospective follow-up.

Citalopram treatment of pediatric recurrent abdominal pain and comorbid internalizing disorders: an exploratory study.

OBJECTIVE: To assess the potential efficacy, tolerability, and safety of citalopram in the treatment of functional pediatric recurrent abdominal pain and comorbid internalizing disorders. METHOD: Twenty-five clinically referred children and adolescents with recurrent abdominal pain aged 7 to 18 years, inclusive, participated in a 12-week, flexible-dose, open-label trial of citalopram. Primary outcome measure was the Clinical Global Impression Scale-Improvement, with responders defined by ratings of 1 (very much improved) or 2 (much improved). Secondary measures included self- and parent reports of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment. Side effects were assessed using a standardized checklist. Data were analyzed using an intent-to-treat format and the last observation carried forward procedure. RESULTS: Twenty-one subjects (84%) were classified as responders (Clinical Global Impression Scale-Improvement score < or =2). Citalopram was generally well tolerated. Four subjects withdrew prematurely, one due to reported visual side effects. Ratings of abdominal pain, anxiety, depression, other somatic symptoms, and functional impairment all improved significantly over the course of the study compared with baseline. CONCLUSIONS: Citalopram is a promising treatment for functional pediatric recurrent abdominal pain and deserves additional study with a randomized, placebo-controlled clinical trial.

Screening for childhood anxiety symptoms in primary care: integrating child and parent reports.

OBJECTIVE: Parents' concerns typically determine the focus of a primary care visit. This study examined which information is lost if child reports are excluded from screening for anxiety. It also explores the use in primary care of the Screen for Child Anxiety Related Emotional Disorders (SCARED) and the Pediatric Symptom Checklist (PSC-17). METHOD: Two hundred thirty-six children (8-12 years 11 months) and their parents completed SCARED and PSC-17 before a primary care visit occurring during discrete periods between June 1999 and March 2001. RESULTS: Child reports yielded higher SCARED scores than parent reports (mean=18.12, SD=12.14 versus 14.43, SD=10.34, p <.001). Somatic/panic and separation anxiety accounted for 73.8% of the excess score from children's reports. The level of parent-reported symptoms did not vary with demographics. Female gender and younger age predicted greater excess reporting by children. Parent and child scores were moderately to highly correlated (R=0.55 total score; 0.40-0.58 subfactors). CONCLUSIONS: There are discrete anxiety domains in which children's reports are likely to yield more information than that of parents. This phenomenon is almost entirely attributable to variations in the level of symptoms reported by children. Studies are needed to design brief screening procedures that integrate parent and child reports and carry age- and gender-adjusted thresholds.
