Actress Patty Duke and journalist Jane Pauley are among the nearly six million American adults who have bipolar disorder, a brain condition that causes unusual shifts in mood, energy and ability to function, according to the National Institute of Mental Health (NIMH). It’s an illness with an impact that can range from minimal to life-threatening, depending on its severity, how well it is treated and lifestyle habits. Yet many people with bipolar disorder don’t even know they have it. Take this quiz to learn about your own risk for bipolar disorder. Just remember: A quiz is not a diagnosis! The only way to be diagnosed correctly is to consult with your family doctor and/or a psychiatrist. If you suspect you may have bipolar disorder, make an appointment right away.
