Irritability without elation in a large bipolar youth sample: frequency and clinical description.

OBJECTIVE: To determine whether some children with bipolar disorder (BP) manifest irritability without elation and whether these children differ on sociodemographic, phenotypic, and familial features from those who have elation and no irritability and from those who have both. METHOD: Three hundred sixty-one youths with BP recruited into the three-site Course and Outcome of Bipolar Illness in Youth study were assessed at baseline and for most severe past symptoms using standardized semistructured interviews. Bipolar disorder subtype was identified, and frequency and severity of manic symptoms were quantified. The subjects were required to have episodic mood disturbance to be diagnosed with BP. The sample was then reclassified and compared based on the most severe lifetime manic episode into three subgroups: elated only, irritable only, and both elated and irritable. RESULTS: Irritable-only and elated-only subgroups constituted 10% and 15% of the sample, respectively. Except for the irritable-only subjects being significantly younger than the other two subgroups, there were no other between-group sociodemographic differences. There were no significant between-group differences in the BP subtype, rate of psychiatric comorbidities, severity of illness, duration of illness, and family history of mania in first- or second-degree relatives and other psychiatric disorders in first-degree relatives, with the exception of depression and alcohol abuse occurring more frequently in the irritability-only subgroup. The elated-only group had higher scores on most DSM-IV mania criterion B items. CONCLUSIONS: The results of this study support the DSM-IV A criteria for mania in youths. Irritable-only mania exists, particularly in younger children, but similar to elated-only mania, it occurs infrequently. The fact that the irritable-only subgroup has similar clinical characteristics and family histories of BP, as compared with subgroups with predominant elation, provides support for continuing to consider episodic irritability in the diagnosis of pediatric BP.

Symptom profiles in pediatric obsessive-compulsive disorder (OCD): the effects of comorbid grooming conditions.

This study sought to examine possible differences in phenomenological features and/or symptom severity of children diagnosed with obsessive-compulsive disorder (OCD) and a comorbid grooming condition (i.e., skin picking and trichotillomania). A total of 202 children receiving a primary diagnosis of OCD were classified into two distinct groups: (1) OCD alone (n=154) and (2) OCD plus a comorbid grooming condition (OCD+grooming; n=48). Analyses revealed that those children presenting with a comorbid grooming condition demonstrated different symptom profiles than those with OCD alone. In addition, parents of these children were more likely to report the presence of tactile/sensory sensitivity than those in the OCD alone group. However, no differences were found with respect to symptom severity via self-report (e.g., OCI) or semi-structured interview (e.g., CY-BOCS). Possible clinical and treatment implications, future areas of research, and limitations to the present study are discussed.

Predictors of spontaneous and systematically assessed suicidal adverse events in the treatment of SSRI-resistant depression in adolescents (TORDIA) study.

OBJECTIVE: The authors sought to identify predictors of self-harm adverse events in treatment-resistant, depressed adolescents during the first 12 weeks of treatment. METHOD: Depressed adolescents (N=334) who had not responded to a previous trial with an SSRI antidepressant were randomized to a switch to either another SSRI or venlafaxine, with or without cognitive behavior therapy. Self-harm events, i.e., suicidal and non-suicidal self-injury adverse events were assessed by spontaneous report for the first 181 participants, and by systematic weekly assessment for the last 153 participants. RESULTS: Higher rates of suicidal (20.8% vs. 8.8%) and nonsuicidal self-injury (17.6% vs. 2.2%), but not serious adverse events (8.4% vs. 7.3%) were detected with systematic monitoring. Median time to a suicidal event was 3 weeks, predicted by high baseline suicidal ideation, family conflict, and drug and alcohol use. Median time to nonsuicidal self-injury was 2 weeks, predicted by previous history of nonsuicidal self-injury. While there were no main effects of treatment, venlafaxine treatment was associated with a higher rate of self-harm adverse events in those with higher suicidal ideation. Adjunctive use of benzodiazepines, while in a small number of participants (N=10) was associated with higher rate of both suicidal and nonsuicidal self-injury adverse events. CONCLUSIONS: Since predictors of suicidal adverse events also predict poor response to treatment, and many of these events occurred early in treatment, improving the speed of response to depression, by targeting of family conflict, suicidal ideation, and drug use may help to reduce their incidence. The relationship of venlafaxine and of benzodiazepines to self-harm events requires further study and clinical caution.

Treatment of selective serotonin reuptake inhibitor-resistant depression in adolescents: predictors and moderators of treatment response.

OBJECTIVE: To advance knowledge regarding strategies for treating selective serotonin reuptake inhibitor (SSRI)-resistant depression in adolescents, we conducted a randomized controlled trial evaluating alternative treatment strategies. In primary analyses, cognitive-behavioral therapy (CBT) combined with medication change was associated with higher rates of positive response to short-term (12-week) treatment than medication alone. This study examines predictors and moderators of treatment response, with the goal of informing efforts to match youths to optimal treatment strategies. METHOD: Youths who had not improved during an adequate SSRI trial (N = 334) were randomized to an alternative SSRI, an alternative SSRI plus CBT, venlafaxine, or venlafaxine plus CBT. Analyses examined predictors and moderators of treatment response. RESULTS: Less severe depression, less family conflict, and absence of nonsuicidal self-injurious behavior predicted better treatment response status. Significant moderators of response to CBT + medication (combined) treatment were number of comorbid disorders and abuse history; hopelessness was marginally significant. The CBT/combined treatment superiority over medication alone was more evident among youths who had more comorbid disorders (particularly attention-deficit/hyperactivity disorder and anxiety disorders), no abuse history, and lower hopelessness. Further analyses revealed a stronger effect of combined CBT + medication treatment among youths who were older and white and had no nonsuicidal self-injurious behavior and longer prestudy pharmacotherapy. CONCLUSIONS: Combined treatment with CBT and antidepressant medication may be more advantageous for adolescents whose depression is comorbid with other disorders. Given the additional costs of adding CBT to medication, consideration of moderators in clinical decision making can contribute to a more personalized and effective approach to treatment.

Comparison of manic and depressive symptoms between children and adolescents with bipolar spectrum disorders.

OBJECTIVE: To compare the most severe lifetime (current or past) mood symptoms, duration of illness, and rates of lifetime comorbid disorders among youth with bipolar spectrum disorders [BP (bipolar-I, bipolar-II and bipolar-not otherwise specified)]. METHODS: A total of 173 children (<12 years) with BP, 101 adolescents with childhood-onset BP, and 90 adolescents with adolescent-onset BP were evaluated with standardized instruments. RESULTS: Depression was the most common initial and frequent episode for both adolescent groups, followed by mania/hypomania. Adolescents with childhood-onset BP had the longest illness, followed by children and then adolescents with adolescent-onset BP. Adjusting for sex, socioeconomic status, and duration of illness, while manic, both adolescent groups showed more 'typical' and severe manic symptoms. Mood lability was more frequent in childhood-onset and adolescents with early-onset BP. While depressed, both adolescent groups showed more severe depressive symptoms, higher rates of melancholic and atypical symptoms, and suicide attempts than children. Depressed children had more severe irritability than depressed adolescents. Early BP onset was associated with attention-deficit hyperactivity disorder, whereas later BP onset was associated with panic, conduct, and substance use disorders. Above-noted results were similar when each BP subtype was analyzed separately. CONCLUSIONS: Older age was associated with more severe and typical mood symptomatology. However, there were differences and similarities in type, intensity, and frequency of BP symptoms and comorbid disorders related to age of onset and duration of BP and level of psychosocial development. These factors and the normal difficulties youth have expressing and modulating their emotions may explain existing complexities in diagnosing and treating BP in youth, particular in young children, and suggest the need for developmentally sensitive treatments.

Prevalence and correlates of physical and sexual abuse in children and adolescents with bipolar disorder.

OBJECTIVE: Adult bipolar disorder (BP) has been associated with lifetime history of physical and sexual abuse. However, there are no reports of the prevalence of abuse in BP youth. The objective of this study was to examine the prevalence and correlates of physical and/or sexual abuse among youth with BP spectrum disorders. METHODS: Four hundred forty-six youths, ages 7 to 17 years (12.7+/-3.2), meeting DSM-IV criteria for BP-I (n=260), BP-II (n=32) or operationalized definition of BP-NOS (n=154) were assessed using the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime version (K-SADS-PL). Abuse was ascertained using the K-SADS. RESULTS: Twenty percent of the sample experienced physical and/or sexual abuse. The most robust correlates of any abuse history were living with a non-intact family (OR=2.6), lifetime history of posttraumatic stress disorder (PTSD) (OR=8.8), psychosis (OR=2.1), conduct disorder (CD) (OR=2.3), and first-degree family history of mood disorder (OR=2.2). After adjusting for confounding demographic factors, physical abuse was associated with longer duration of BP illness, non-intact family, PTSD, psychosis, and first-degree family history of mood disorder. Sexual abuse was associated with PTSD. Subjects with both types of abuse were older, with longer illness duration, non-intact family, and greater prevalence of PTSD and CD as compared with the non-abused group. LIMITATIONS: Retrospective data. Also, since this is a cross-sectional study, no inferences regarding causality can be made. CONCLUSION: Sexual and/or physical abuse is common in youth with BP particularly in subjects with comorbid PTSD, psychosis, or CD. Prompt identification and treatment of these youth is warranted.

Phenomenology of Early Childhood Onset Obsessive Compulsive Disorder.

This paper describes the phenomenological features of early childhood onset obsessive compulsive disorder (OCD; defined as children meeting DSM-IV criteria for OCD with age of onset <8 years). Fifty-eight children (ages 4-8) were included in the sample. OCD and comorbid diagnoses were determined by structured interview, and OCD severity was measured using the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). Mean age of OCD onset was almost five, and mean age of presentation was between 6 and 7. Mean symptom severity was in the moderately severe range. Comorbidity and family history of OCD were common. Contamination and aggressive/catastrophic obsessions and washing and checking compulsions were endorsed most frequently. Results indicate that early childhood onset OCD may have a lower boy to girl ratio and lower rates of depressive disorders, but may be similar to later childhood onset OCD in terms of OCD symptom presentation and severity.

Preliminary findings regarding overweight and obesity in pediatric bipolar disorder.

OBJECTIVE: Overweight/obesity is highly prevalent among adults with bipolar disorder and has been associated with illness severity. Little is known regarding overweight/obesity among youth with bipolar disorder. METHOD: Subjects were 348 youths aged 7 to 17 years who met DSM-IV criteria for bipolar I or bipolar II disorder or study-operationalized criteria for bipolar disorder not otherwise specified and were enrolled in the Course and Outcome of Bipolar Illness in Youth study. Age- and sex-adjusted body mass index was computed according to International Obesity Task Force cut points, based on self- and parent-reported height and weight, to determine overweight/obesity. The study was conducted from October 2000 to July 2006. RESULTS: Overweight/obesity was prevalent among 42% of subjects. The most robust predictors of overweight/obesity in a logistic regression model were younger age, nonwhite race, lifetime physical abuse, substance use disorders, psychiatric hospitalizations, and exposure to ≥ 2 medication classes associated with weight gain. CONCLUSIONS: The prevalence of overweight/obesity among youth with bipolar disorder may be modestly greater than in the general population. Moreover, similar to adults, overweight/obesity among youth with bipolar disorder may be associated with increased psychiatric burden. These preliminary findings underscore the importance of early identification of overweight/obesity among youth with bipolar disorder. Future studies are needed to clarify the direction of the associations between overweight/obesity and the identified predictors and to compare the prevalence of overweight/obesity among youth with bipolar disorder versus other psychiatric disorders.

Significance of cigarette smoking among youths with bipolar disorder.

Cigarette smoking among adults with bipolar disorder (BP) correlates with psychosis, substance use disorders (SUD), and suicidality. Little is known regarding smoking among youths with BP. Youths with BP (n = 441) were divided into three smoking groups: Never, Ever, and Daily. Twenty-five percent reported any smoking (11% daily, 14% ever). Ever and Daily subjects had significantly greater lifetime prevalence of suicide attempts, physical abuse, conduct disorder, and SUD compared to Never subjects. Daily heavy smokers had greater prevalence of SUD and suicide attempts, and worse depression versus daily light smokers. Smoking among youths with BP is independently associated with suicide attempts and SUD.

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.

Early childhood OCD: preliminary findings from a family-based cognitive-behavioral approach.

OBJECTIVE: To examine the relative efficacy of family-based cognitive-behavioral therapy (CBT) versus family-based relaxation treatment (RT) for young children ages 5 to 8 years with obsessive-compulsive disorder (OCD). METHOD: Forty-two young children with primary OCD were randomized to receive 12 sessions of family-based CBT or family-based RT. Assessments were conducted before and after treatment by independent raters blind to treatment assignment. Primary outcomes included scores on the Children's Yale-Brown Obsessive Compulsive Scale and Clinical Global Impressions-Improvement. RESULTS: For the intent-to-treat sample, CBT was associated with a moderate treatment effect (d = 0.53), although there was not a significant difference between the groups at conventional levels. For the completer sample, CBT had a large effect (d = 0.85), and there was a significant group difference favoring CBT. In the intent-to-treat sample, 50% of children in the CBT group achieved remission as compared to 20% in the RT group. In the completer sample, 69% of children in the CBT group achieved a clinical remission compared to 20% in the RT group. CONCLUSIONS: Results indicate that children with early-onset OCD benefit from a treatment approach tailored to their developmental needs and family context. CBT was effective in reducing OCD symptoms and in helping a large number of children achieve a clinical remission.

Switching to another SSRI or to venlafaxine with or without cognitive behavioral therapy for adolescents with SSRI-resistant depression: the TORDIA randomized controlled trial.

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 clinical sample of 334 patients aged 12 to 18 years with a primary diagnosis of major depressive disorder that had not responded to a 2-month initial treatment with an SSRI, conducted at 6 US academic and community clinics from 2000-2006. INTERVENTIONS: Twelve weeks of: (1) switch to a second, different SSRI (paroxetine, citalopram, or fluoxetine, 20-40 mg); (2) switch to a different SSRI plus cognitive behavioral therapy; (3) switch to venlafaxine (150-225 mg); or (4) switch to venlafaxine plus cognitive behavioral therapy. MAIN OUTCOME MEASURES: Clinical Global Impressions-Improvement score of 2 or less (much or very much improved) and a decrease of at least 50% in the Children's Depression Rating Scale-Revised (CDRS-R); and change in CDRS-R over time. RESULTS: Cognitive behavioral therapy plus a switch to either medication regimen showed a higher response rate (54.8%; 95% confidence interval [CI], 47%-62%) than a medication switch alone (40.5%; 95% CI, 33%-48%; P = .009), but there was no difference in response rate between venlafaxine and a second SSRI (48.2%; 95% CI, 41%-56% vs 47.0%; 95% CI, 40%-55%; P = .83). There were no differential treatment effects on change in the CDRS-R, self-rated depressive symptoms, suicidal ideation, or on the rate of harm-related or any other adverse events. There was a greater increase in diastolic blood pressure and pulse and more frequent occurrence of skin problems during venlafaxine than SSRI treatment. CONCLUSIONS: For adolescents with depression not responding to an adequate initial treatment with an SSRI, the combination of cognitive behavioral therapy and a switch to another antidepressant resulted in a higher rate of clinical response than did a medication switch alone. However, a switch to another SSRI was just as efficacious as a switch to venlafaxine and resulted in fewer adverse effects. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00018902.

Atomoxetine treatment of ADHD in children with comorbid Tourette syndrome.

OBJECTIVE: This study examines changes in severity of tics and ADHD during atomoxetine treatment in ADHD patients with Tourette syndrome (TS). METHOD: Subjects (7-17 years old) with ADHD (Diagnostic and Statistical Manual of Mental Disorders, DSM-IV) and TS were randomly assigned to double-blind treatment with placebo (n = 56) or atomoxetine (0.5-1.5 mg/kg/day, n = 61) for approximately 18 weeks. RESULTS: Atomoxetine subjects showed significantly greater improvement on ADHD symptom measures. Treatment was also associated with significantly greater reduction of tic severity on two of three measures. Significant increases were seen in mean pulse rate and rates of treatment-emergent nausea, decreased appetite, and decreased body weight. No other clinically relevant treatment differences were observed in any other vital sign, adverse event, laboratory parameter, or electrocardiographic measure. CONCLUSION: Atomoxetine is efficacious for treatment of ADHD and its use appears well tolerated in ADHD patients with comorbid TS.

Factors associated with mental health service utilization among bipolar youth.

OBJECTIVES: This study aims to characterize patterns of mental health service utilization within a sample of bipolar youth. Demographic variables, youth bipolar characteristics, youth comorbid conditions, and parental psychopathology were examined as predictors of treatment utilization across different levels of care. METHODS: A total of 293 bipolar youth (aged 7-17 years) and their parents completed a diagnostic interview, family psychiatric history measures, and an assessment of mental health service utilization. Demographic and clinical variables were measured at baseline and mental health service use was measured at the six-month follow-up. RESULTS: Approximately 80% of bipolar youth attended psychosocial treatment services over the span of 6 months. Of those who attended treatment, 67% attended only outpatient services, 22% received inpatient/partial hospitalization, and 12% received residential/therapeutic school-based services. Using multinomial logistic regression, older age, female gender, and bipolar characteristics, including greater symptom severity and rapid cycling, were found to predict higher levels of care. Youth suicidal and non-suicidal self-injurious behavior, comorbid conduct disorder, and parental substance use disorders also predicted use of more restrictive treatment settings. CONCLUSIONS: Results underscore the importance of assessing for and addressing suicidality, comorbid conduct disorder, and parental substance use disorders early in the treatment of bipolar youth to potentially reduce the need for more restrictive levels of care.

Cognitive behavioral treatment for young children with obsessive-compulsive disorder.

Obsessive-compulsive disorder (OCD) is a distressing and functionally impairing disorder that can emerge as early as age 4. Cognitive behavior therapy (CBT) for OCD in youth shows great promise for amelioration of symptoms and associated functional impairment. However, the empirical evidence base for the efficacy of CBT in youth has some significant limitations, particularly as related to treating the very young child with OCD. This report includes a quantitative review of existing child CBT studies to evaluate evidence for the efficacy of CBT for OCD. It identifies gaps in the literature that, when addressed, would enhance the understanding of effective treatment in pediatric OCD. Finally, it presents a proposed research agenda for addressing the unique concerns of the young child with OCD.

Tics moderate treatment outcome with sertraline but not cognitive-behavior therapy in pediatric obsessive-compulsive disorder.

BACKGROUND: The presence of a comorbid tic disorder may predict a poorer outcome in the acute treatment of pediatric obsessive-compulsive disorder (OCD). METHODS: Using data from the National Institute of Mental Health (NIMH)-funded Pediatric OCD Treatment Study (POTS) that compared cognitive-behavior therapy (CBT), medical management with sertraline (SER), and the combination of CBT and SER (COMB), to pill placebo (PBO) in children and adolescents with OCD, we asked whether the presence of a comorbid tic disorder influenced symptom reduction on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) after 12 weeks of treatment. RESULTS: Fifteen percent (17 of 112) of patients exhibited a comorbid tic disorder. In patients without tics, results replicated previously published intent-to-treat outcomes: COMB > CBT > SER > PBO. In patients with a comorbid tic disorder, SER did not differ from PBO, while COMB remained superior to CBT and CBT remained superior to PBO. CONCLUSIONS: In contrast to CBT outcomes, which are not differentially impacted, tic disorders appear to adversely impact the outcome of medication management of pediatric OCD. Children and adolescents with obsessive-compulsive disorder and a comorbid tic disorder should begin treatment with cognitive-behavior therapy alone or the combination of cognitive-behavior therapy plus a serotonin reuptake inhibitor.

Childhood-onset bipolar disorder: Evidence for increased familial loading of psychiatric illness.

OBJECTIVE: To determine whether childhood-onset bipolar disorder (BP) is associated with an increased psychiatric family history compared with adolescent-onset BP. METHOD: Semistructured psychiatric interviews were conducted for 438 youth with BP spectrum disorders. To evaluate the effects of age at onset and psychiatric family history, the sample was divided into childhood-onset BP (age and BP onset <12 years; n = 192), adolescents with early-onset BP (age > or =12 years and BP onset <12 years; n = 136), and adolescents with late-onset BP (age and BP onset > or =12 years; n = 110). Lifetime family history of psychiatric illness was ascertained for first- and second-degree relatives through both direct interview of caretakers and the Family History Screen. RESULTS: After significant demographic and clinical factors were controlled for, children and adolescents with childhood-onset BP showed higher percentages of positive first-degree family history for depression, anxiety, attention-deficit/hyperactivity, conduct, and substance dependence disorders and suicidal behaviors compared with adolescents with late onset. Subjects with childhood-onset BP also showed elevated familial loading for depression and attention-deficit/hyperactive disorder in second-degree relatives. CONCLUSIONS: These data support a model that postulates a higher density of familial risk for a broad range of psychopathology in childhood-onset BP.

Triple board training and new "portals" into child psychiatry training.

Originally an experiment in medical training, the triple board program has established itself as a permanent and successful training program. It offers a viable 5-year alternative to the traditional 7 to 8 years of residency training required for board eligibility in pediatrics, general psychiatry, and child and adolescent psychiatry. One primary objective of this course was to address for workforce shortage of child psychiatrists by recruiting medical students who may otherwise have pursued general pediatrics. The second objective was to bridge the gap between child psychiatry and pediatrics by training physicians proficient in the culture, language, and content of both specialty fields. Although the shortage crisis continues, both objectives were met. The success of the triple board experiment has facilitated further consideration and support for the development of other novel training portals into child psychiatry.

Phenomenology of children and adolescents with bipolar spectrum disorders.

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 primary caretaker. SETTING: Outpatient and inpatient units at 3 university centers. PARTICIPANTS: A total of 438 children and adolescents (mean +/- SD age, 12.7 +/- 3.2 years) with BP-I (n = 255), BP-II (n = 30), or BP-NOS (n = 153). MAIN OUTCOME MEASURES: Lifetime psychiatric history and family history of psychiatric disorders. RESULTS: Youth with BP-NOS were not diagnosed as having BP-I primarily because they did not meet the DSM-IV duration criteria for a manic or mixed episode. There were no significant differences among the BP-I and BP-NOS groups in age of onset, duration of illness, lifetime rates of comorbid diagnoses, suicidal ideation and major depression, family history, and the types of manic symptoms that were present during the most serious lifetime episode. Compared with youth with BP-NOS, subjects with BP-I had more severe manic symptoms, greater overall functional impairment, and higher rates of hospitalization, psychosis, and suicide attempts. Elevated mood was present in 81.9% of subjects with BP-NOS and 91.8% of subjects with BP-I. Subjects with BP-II had higher rates of comorbid anxiety disorders compared with the other 2 groups and had less functional impairment and lower rates of psychiatric hospitalization than the subjects with BP-I. CONCLUSIONS: Children and adolescents with BP-II and BP-NOS have a phenotype that is on a continuum with that of youth with BP-I. Elevated mood is a common feature of youth with BP-spectrum illness.

Pediatric bipolar disease: current and future perspectives for study of its long-term course and treatment.

AIM AND METHODS: Findings from recent long-term, prospective longitudinal studies of the course, outcome and naturalistic treatment of adults with bipolar illness are highlighted as background for long-term developmental study of pediatric bipolar illness. RESULTS: Accumulating knowledge of bipolar illness in adults underscores a high risk for multiple recurrences through the lifespan, significant medical morbidity, high rates of self-harm, economic and social burden and frequent treatment resistance with residual symptoms between major episodes. At present, there is no empirical foundation to support any assumption about the long-term course or outcome of bipolar illness when it arises in childhood or adolescence, or the effects of conventional pharmacotherapies in altering its course and limiting potentially adverse outcomes. The proposed research articulates specific descriptive aims that draw on adult findings and outlines core methodological requirements for such an endeavor. CONCLUSIONS: Innovations in the description and quantitative analysis of prospective longitudinal clinical data must now be extended to large, systematically ascertained pediatric cohorts recruited through multicenter studies if there is to be a meaningful scientific advance in our knowledge of the enduring effects of bipolar illness and the potential value of contemporary approaches to its management.
