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.
