Abstract The authors assessed how family history loading affected the course of illness in patients from the United States. A total of 676 outpatients with bipolar disorder from the United States rated their illness and provided a parental and grandparental history of mood disorder, substance abuse, and other clinical conditions. A positive family history for each illness was associated with almost all of the seven poor prognosis factors established in the study (abuse in childhood, early onset, anxiety and substance abuse comorbidity, rapid cycling, multiple episodes, and worsening of severity or frequency of episodes). Family history for psychiatric difficulties in parents and grandparents was associated with a more complex and difficult course of bipolar illness.
