About Bipolar Disorder
It is estimated that 27 million people worldwide(2) suffer from bipolar disorder, also known as manic-depressive disorder. It is characterized by debilitating mood swings, from extreme highs (mania) to extreme lows (depression). Signs of mania include euphoria, extreme irritability or rage, accelerated or disorganized thinking and an increase in risky behaviors. Signs of depression include intense sadness or despair, loss of energy, insomnia and suicidal thoughts.
A classification of patients identified as "rapid-cycling" and also having four or more episodes during the previous 12 months, is estimated to occur in approximately 10-20% of patients with bipolar disorder seen in mood disorder clinics. The types of mood episodes (manic, depressed, mixed) seen in these patients can occur in any pattern. The course of their illness is characterized by a requirement for more health care resources, more concomitant medications and poorer outcomes.(4)
