Background: The rate of switching from major depression to bipolar disorder is high in children. Predicting who is at risk for switching poses unique challenges and is of high clinical relevance. Our aim was to examine the existing scientific literature elucidating if certain clinical correlates predict ultimate bipolar switches in children initially presenting with a depressive episode.
Methods: We conducted a systematic literature search of studies assessing the risk factors for bipolar switching in youth. In all, seven studies fit our a priori criteria and were thus included in our qualitative review.
Results: Together, these papers found that manic switches in pediatric depression can be predicted by several risk factors, including positive family history of mood disorders, emotional and behavioral dysregulation, subthreshold mania, and psychosis.
Limitations: We identified only seven prospective informative studies for our review. The majority of subjects included in these studies were referred and Caucasian. Thus, the results may not generalize to other community samples and other ethnicities.
Conclusions: These findings can help alert clinicians of the risk of manic switches.
