    CONTEXT: Only about 60% of adolescents with depression will show an adequate clinical response to an initial treatment trial with a selective serotonin reuptake inhibitor (SSRI). There are no data to guide clinicians on subsequent treatment strategy.

    OBJECTIVE: To evaluate the relative efficacy of 4 treatment strategies in adolescents who continued to have depression despite adequate initial treatment with an SSRI.

    DESIGN, SETTING, AND PARTICIPANTS: Randomized controlled trial of a ...

    CONTEXT: There was a paucity of comparative pharmacological research for initial treatment of bipolar I disorder, manic or mixed phase, in children and adolescents.

    OBJECTIVE: To investigate which medication to administer first to antimanic medication-naive subjects.

    DESIGN, SETTING, AND PARTICIPANTS: The Treatment of Early Age Mania (TEAM) study recruited 6- to 15-year-old children and adolescents with DSM-IV bipolar I disorder (manic or mixed phase) at 5 US sites from 2003 to 2008 into ...

    OBJECTIVE: The aim of the Longitudinal Assessment of Manic Symptoms (LAMS) study is to examine differences in psychiatric symptomatology, diagnoses, demographics, functioning, and psychotropic medication exposure in children with elevated symptoms of mania (ESM) compared to youth without ESM. This article describes the initial demographic information, diagnostic and symptom prevalence, and medication exposure for the LAMS cohort that will be followed longitudinally.

    OBJECTIVE: Anxiety disorders are among the most common comorbid conditions in youth with bipolar disorder. We aimed to examine the prevalence and correlates of comorbid anxiety disorders among youth with bipolar disorder.

    METHOD: As part of the Course and Outcome of Bipolar Youth study, 446 youth, ages 7 to 17 years, who met DSM-IV criteria for bipolar I disorder (n = 260) or bipolar II disorder (n = 32) or met operationalized criteria for bipolar disorder not otherwise specified (n = ...

    OBJECTIVE: To compare the psychopathology and longitudinal course of attention-deficit/hyperactivity disorder (ADHD) symptomatology and global functioning between the offspring with ADHD of parents with bipolar disorder and the offspring with ADHD of community control parents.

    METHOD: One hundred twenty-two offspring with ADHD of parents with bipolar disorder and 48 offspring with ADHD of control parents from the Pittsburgh Bipolar Offspring Study (BIOS) were included. DSM-IV lifetime ...

    CONTEXT: Children and adolescents who present with manic symptoms frequently do not meet the full DSM-IV criteria for bipolar I disorder (BP-I).

    OBJECTIVE: To assess the clinical presentation and family history of children and adolescents with BP-I, bipolar II disorder (BP-II), and bipolar disorder not otherwise specified (BP-NOS).

    DESIGN: Subjects and their primary caretaker were assessed by semistructured interview, and family psychiatric history was obtained from interview of the ...

    OBJECTIVE: The purpose of this study was to report on the outcome of participants in the Treatment of Resistant Depression in Adolescents (TORDIA) trial after 24 weeks of treatment, including remission and relapse rates and predictors of treatment outcome.

    METHOD: Adolescents (ages 12-18 years) with selective serotonin reuptake inhibitor (SSRI)-resistant depression were randomly assigned to either a medication switch alone (alternate SSRI or venlafaxine) or a medication switch plus ...

    OBJECTIVE: To evaluate parent-child bonding and familial functioning in depressed children, children at high risk for depression, and low-risk controls.

    METHOD: Diagnoses of children and their relatives were obtained via structured interviews with all available informants. Depressed children (n = 54) received a diagnosis of current major depressive disorder (MDD). The high-risk children (n = 21) had no lifetime diagnoses of mood disorders, but at least one first-degree relative with a ...

    OBJECTIVE: Anxiety disorders are among the most common comorbid conditions in youth with bipolar disorder, but, to our knowledge, no studies examined the course of anxiety disorders in youth and adults with bipolar disorder.

    METHOD: As part of the Course and Outcome of Bipolar Youth study, 413 youth, ages 7 to 17 years who met criteria for Diagnostic and Statistical Manual, Fourth Edition (DSM-IV) bipolar I disorder (n = 244), bipolar II disorder (n = 28), and operationally defined ...

    OBJECTIVE: The Child Behavior Checklist is sometimes used to assess sleep disturbance despite not having been validated for this purpose. This study examined associations between the Child Behavior Checklist sleep items and other measures of sleep.

    METHOD: Participants were 122 youth (61% female, aged 7 through 17 years) with anxiety disorders (19%), major depressive disorder (9%), both anxiety and depression (26%), or a negative history of any psychiatric disorder (46%). Parents ...

    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 ...

    OBJECTIVE: Sleep problems are a cardinal symptom of depression in children and adolescents and caffeine use is a prevalent and problematic issue in youth; yet little is known about caffeine use and its effects on sleep in youth with depression. We examined caffeine use and its relation to sleep and affect in youth's natural environments.

    METHODS: Thirty youth with major depressive disorder (MDD) and 23 control youth reported on caffeine use, sleep, and affect in their natural environment ...

    Offspring of depressed parents are at risk for depression and recent evidence suggests that reduced positive affect (PA) may be a marker of risk. We investigated whether self-reports of PA and fMRI-measured striatal response to reward, a neural correlate of PA, are reduced in adolescent youth at high familial risk for depression (HR) relative to youth at low familial risk for depression (LR). Functional magnetic resonance imaging assessments were conducted with 14 HR and 12 LR youth. All ...

    CONTEXT: Despite the high morbidity associated with bipolar disorder (BP), few studies have prospectively studied the course of this illness in youth.

    OBJECTIVE: To assess the longitudinal course of BP spectrum disorders (BP-I, BP-II, and not otherwise specified [BP-NOS]) in children and adolescents.

    DESIGN: Subjects were interviewed, on average, every 9 months for an average of 2 years using the Longitudinal Interval Follow-up Evaluation.

    SETTING: Outpatient and inpatient units at 3 ...

    First-degree (N = 195) and second-degree (N = 785) adult relatives of prepubertal children with major depression (N = 48), children with nonaffective psychiatric disorders (N = 20), and normal children (N = 27) were assessed by the Family History-Research Diagnostic Criteria method (FH-RDC), except for the adult informant (usually the mother), who was directly interviewed. Compared with normal controls, prepubertal children with major depressive disorder (MDD) had significantly higher ...
