There have been several investigations of divalproex for the treatment of mood symptoms in children at familial risk for bipolar disorder (Chang et al., 2002; Findling et al., 2002). Chang et al., found a significant reduction in mood symptoms and improvement in overall functioning following treatment with divalproex in 23 children who did not have bipolar I disorder but who were diagnosed with mood symptoms/syndromes and who had a parent with bipolar disorder (Chang et al., 2002). Similarly, Findling et al. reported that children with mood symptoms and a multigenerational family history of bipolar disorder had a significant reduction in mood symptoms when treated with divalproex compared with placebo (Findling et al., 2002). To our knowledge, there have been no studies evaluating the use of atypical antipsychotics for the treatment of children at familial risk for developing bipolar disorder who are diagnosed with mood disorders other than bipolar I disorder.
