The United States has the highest occurrence of Bipolar disorder according to a worldwide study released in March, that surveyed people from 11 nations as part of the World Health Organization's World Mental Health Survey Initiative.
Current information suggests that 2.4 percent of people worldwide have suffered from the disorder at some point in their lives. The United States came in with almost double the average number with 4.4 percent of people claiming to have experienced bipolar symptoms within their lifetime.
Most concerning, according to information collected between 2002 and 2007 the Archives of General Psychiatry found that, one in every five persons with bipolar disorder have made suicide attempts.
Despite the growing number of cases of bipolar disorder within the United States, those who said they had the disorder within the past 12 months declined to 2.8 percent.
"Treatment needs for bipolar spectrum disorder are often unmet," said the LA Times, "Particularly in low-income countries."
