The medical community focused on the topic of children and bipolar disorder in September with the news that there has been a 4,000 percent increase in the diagnosis in children since 1994. This increase occurred despite the fact that bipolar disorder is extremely difficult to diagnose in children. Its symptoms often mimic other, more common childhood disorders, especially attention deficit hyperactivity disorder. The increase in diagnosis of bipolar disorder in children alone raised some controversy. But the controversy about bipolar disorder in children escalated when the topic turned to treatment.
