Bipolar I disorder is a condition that causes periods of severe changes in your mood, activity levels, energy, and ability to carry out everyday tasks. These changes are commonly called “mood episodes.”
Although you may feel like you’re the only one if it’s happening to you, there are millions of Americans affected by bipolar disorder each year.
While anyone can develop bipolar I disorder, it often starts in the late teen or early adult years and it lasts a lifetime. Children and older adults may develop bipolar I disorder as well.
Medical researchers believe that it can result from many factors, including an imbalance of certain chemicals in the brain called neurotransmitters, which may be too high or too low.
