The U.S. Food and Drug Administration has a resource page that provides an overview of bipolar I and bipolar II disorders. Symptoms, FDA-approved treatments, what to do if you suspect bipolar disorder to be the cause of your symptoms, what to do if you’re in crisis, and other considerations are all discussed on the FDA’s website. Ups and downs in mood, such as alternating between feeling depressed and excited, could point to this brain disorder, so it is important to learn more and seek help from medical and mental health professionals.
