The studies include children adopted into bipolar households, and they do not develop bipolar disorder as often as biological children; and also children of parents with bipolar disorder adopted by non-bipolar and relatively healthy families that develop bipolar disorder nonetheless.

If both parents have bipolar disorder, the likelihood of their child developing bipolar disorder rises to 40%.
