Lithium Effective for Maintenance Treatment of Childhood-Onset Bipolar Disorder
Evidence has been accumulating that lithium is effective in the treatment of young people with bipolar disorder. In a study by Robert Findling and colleagues published in the Journal of the American Academy of Child and Adolescent Psychiatry in 2018, participants aged 7–17 who responded well to lithium during a 24-week study were then randomized to receive either lithium continuation (17 participants) or placebo (14 participants) for 28 more weeks.
Those who continued lithium treatment were more likely to stay in the study. Participants who discontinued the study mostly reported that they did so due to re-emergence of their mood symptoms (mostly in the placebo group).
Lithium was well-tolerated and was not associated with any more weight gain than placebo. This study adds to the growing literature on the effectiveness and tolerability of lithium both acutely and in maintenance treatment in childhood bipolar disorder.
