Abstract
INTRODUCTION Bipolar disorder (BD) hospitalization rates in children and adolescents vary greatly across place and over time. There are no population-based studies on youth BD hospitalizations in Spain. METHODS We identified all patients aged 10-19 hospitalized due to BD in Spain between 2000 and 2021, examined their demographic and clinical characteristics, and assessed temporal trends in hospitalizations - overall and stratified by age and presence of additional psychiatric comorbidity. We used Joinpoint regressions to identify inflection points and quantify whole-period and annual percentage changes (APCs) in trends. RESULTS Of 4770 BD hospitalizations in 10-19-year-olds between 2000 and 2021 (average annual rate: 4.8 per 100,000), over half indicated an additional psychiatric comorbidity, most frequently substance abuse (62.2%), mostly due to cannabis (72.4%). During the study period, admissions increased twofold with an inflection point: Rates increased annually only between 2000 and 2008, for APCs 34.0% (95% confidence interval: 20.0%, 71.1%) among 10-14-year-olds, 10.3% (6.4%, 14.3%) among 15-19-year-olds, and 15.5% (11.5%, 22.7%) among patients with additional psychiatric comorbidity. Between 2009 and 2021, rates decreased moderately among 10-14-year-olds - APC: -8.3% (-14.1%, -4.4%) and slightly among 15-19-year-olds without additional psychiatric comorbidity - APC: -2.6(-5.7, -1.0), remaining largely stable among 15-19-year-olds overall. CONCLUSIONS Recent trends in hospitalization due to BD in 10-19-year-olds in Spain indicate salient increases in the early 2000s - especially among (i) patients aged 10-14 (decreasing moderately after 2009 among 10-14-year-olds and plateauing among 15-19-year-olds) and (ii) patients with additional psychiatric comorbidity (i.e., cannabis use disorder). These findings suggest links with recent changes in clinical practices for children and recent trends in substance use among Spanish youth.

Abstract
AIMS This article examines the ongoing debate concerning the diagnosis of bipolar disorder in children and adolescents. This contentious issue has generated robust discussion over the past two decades without consensus, and as such the true prevalence of so-called paediatric bipolar disorder (PBD) remains unknown. In this article we offer a solution to break this deadlock. METHODS Recent meta-analyses and additional literature concerning the definition and prevalence of PBD was critically reviewed with a view to understanding the perspectives of those developing the taxonomy of PBD, and those engaged in research and clinical practice. RESULTS A key finding is the lack of iteration and meaningful communication between the various groups interested in PBD that stems from deep-seated problems within our classificatory systems. This undermines our research efforts and complicates clinical practice. These problems make the already difficult diagnosis of bipolar disorder in adults even more challenging to transpose to younger populations, and additional complexities arise when parsing clinical phenomenology from normative developmental changes in youth. Therefore, in those manifesting bipolar symptoms post-puberty, we argue for the use of adolescent bipolar disorder to describe bipolar symptoms whereas in pre-pubertal children, we propose a reconceptualisation that allows symptomatic treatment to be advanced whilst requiring critical review of these symptoms over time. CONCLUSION Significant changes in our current taxonomy are necessary and to be clinically meaningful, these revisions to our diagnoses need to be developmentally-informed.

Abstract
OBJECTIVES Paediatric bipolar disorder - bipolar disorder occurring in prepubertal children - is a diagnosis subject to considerable controversy. Whilst historically considered to be very rare, proponents since the 1990s have argued that mania can present differently in children and, as such, is much more common than previously thought. Such proposals raise questions about the validity of proposed phenotypes and potential risks of iatrogenic harm. METHODS I critically examine the construct of paediatric bipolar disorder using Robins and Guze's (1970, American Journal of Psychiatry126, 983-987) influential criteria for the validity of a psychiatric diagnosis. I review, in turn, evidence relating to its clinical description, delimitation from other conditions, follow-up studies, family studies, laboratory studies, and treatment response. RESULTS Across domains, existing research highlights significant challenges establishing the diagnosis. This includes significant heterogeneity in operationalising criteria for children; variable or poor inter-rater reliability; difficulty distinguishing paediatric bipolar disorder from other conditions; large differences in rates of diagnosis between the United States of America and other countries; limited evidence of continuity with adult forms; and a lack of evidence for proposed paediatric phenotypes in children at genetic high-risk of the condition. Laboratory and treatment studies are limited, but also do not provide support for the construct. CONCLUSIONS Evidence for the more widespread existence of paediatric bipolar disorder and its various proposed phenotypes remains weak. The ongoing popularity of the diagnosis, most evident in America, may reflect social pressures and broader limitations in psychiatric nosology. The uncertainty around the diagnosis highlights the need for careful longitudinal assessment of children potentially affected.

Abstract
OBJECTIVE To examine patterns of remission of pediatric bipolar I (BP-I) disorder attending to syndromatic, symptomatic, and functional outcomes from childhood to adolescent and young adult years. METHODS We analyzed data from a six-year prospective follow-up study of youths aged 6-17 years with BP-I disorder. Subjects were comprehensively assessed at baseline and subsequently at four, five, and six years thereafter. Assessments included structured diagnostic interviews and measures of psychosocial and educational functioning. Patterns of remission were calculated attending to whether syndromatic, symptomatic, and functional remission were achieved. RESULTS Kaplan-Meier failure functions revealed that the probability of functional recovery from pediatric BP-I disorder was very low. Of the 88 youths assessed, only 6% (N = 5) of the sample were euthymic with normal functioning during the year prior to their last follow-up assessment (average follow-up time = 5.8 ± 1.8 years). CONCLUSIONS These results provide compelling evidence of the high level of persistence of pediatric BP-I disorder. Symptomatic and functional remission were uncommon and most subjects continued to demonstrate high morbidity into late adolescence and early adulthood.

Parry P, Allison S, Bastiampillai T. 'Pediatric Bipolar Disorder' rates are still lower than claimed: a re-examination of eight epidemiological surveys used by an updated meta-analysis. Int J Bipolar Disord 2021; 9:21. [PMID: 34170440 PMCID: PMC8233426 DOI: 10.1186/s40345-021-00225-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 04/15/2021] [Indexed: 01/20/2023] Open
Abstract
Background ‘Pediatric bipolar disorder’ (PBD) is a controversial diagnosis with varying rates of clinical diagnosis. A highly cited meta-analysis (Van Meter et al. 2011) of a dozen epidemiological surveys suggested a global community prevalence of PBD of 1.8%. This was updated to 3.9% with eight additional surveys (Van Meter et al. 2019a). In terms of the Cochrane Handbook for Systematic Reviews of Interventions, the heterogenous community surveys were arguably unsuitable for statistical meta-analysis and warranted a narrative analysis. A narrative analysis (Parry et al. 2018) of the original 12 surveys concluded rates of PBD were substantially lower than 1.8% and led to a nine-article debate on the validity, arguable overdiagnosis and iatrogenic aspects of the PBD diagnosis (e.g. Carlson and Dubicka Child Adolesc Mental Health 21:86–87, 2019). This article extends the narrative analysis to include the eight newer community surveys. Methods A narrative analysis of the methodologies and the prevalence rates reported by the epidemiological surveys. Results Across all twenty surveys there was significant variation in methodologies and reported prevalence rates. Of the eight newer surveys, five (two Brazilian, one English, one Turkish, one United States) provided information of pre-adolescent prevalence rates of bipolar spectrum disorder. These pre-adolescent rates were zero or close to zero. Rates of adolescent hypomania and mania were higher, but follow-up data in two studies suggested hypomania might sometimes achieve prolonged remission or not lead to adult bipolar disorder. Limitations Methods in the original surveys vary and criteria used for various bipolar diagnoses were not always fully described. This limitation applies to a narrative analysis but also to a statistical meta-analysis. Conclusion Bipolar disorder is very rare in childhood and rare in adolescence. PBD as a diagnostic construct fails to correlate with adult bipolar disorder and the term should be abandoned. Hypomanic syndromes in adolescence may not always progress to adult bipolar disorder. Early diagnosis of bipolar disorder is important, but over-diagnosis risks adverse iatrogenic consequences.

Abstract
BACKGROUND Evidence from epidemiological, clinical and high-risk studies has established that the peak period of risk for onset of bipolar disorder spans late adolescence and early adulthood. However, the proposal of the existence of a pre-pubertal form of bipolar disorder manifesting in early childhood created substantial debate. In this narrative review, the literature and contributing factors pertaining to the controversy surrounding the proposed pre-pubertal bipolar disorder subtype are discussed. The resolution of the debate and lessons learned are highlighted. MAIN BODY In the mid 1990s US researchers proposed that chronic irritability and explosive temper in pre-pubertal children with pre-existing ADHD and/or other learning and developmental disorders might represent a variant of mania. A number of factors contributed to this proposal including severely ill children with no diagnostic home given changes in the ADHD DSM diagnostic criteria and over-reliance on symptoms and structured interviews rather than on a clinical assessment incorporating developmental history, social context and clinical course. Prospective studies of children at high familial risk did not support the proposed pre-pubertal bipolar phenotype; but rather provided convergent evidence that bipolar disorder onset in adolescence and early adulthood not uncommonly preceded by sleep and internalizing symptoms and most often debuting as depression in adolescence (after puberty). Epidemiological studies of population and hospital discharge data provided evidence that the pre-pubertal bipolar phenotype was largely a US driven phenomenon. CONCLUSIONS Psychiatric diagnosis is particularly challenging given the current lack of objective biomarkers. However, validity and utility of clinical diagnoses can be strengthened if all available predictive information is used to formulate a diagnosis. As in other areas of medicine, critical information required to make a valid diagnosis includes developmental history, clinical course, family history and treatment response-weighed against the known trajectories of classical disorders. Moreover, given that psychiatric disorders are in evolution over childhood and adolescence and symptoms, in of themselves, are often non-specific, a thorough clinical assessment incorporating collateral history and psychosocial context is paramount. Such an approach might have avoided or at least brought a more timely resolution to the debate on pre-pubertal mania.
