Bipolar mood disorder, commonly called bipolar, is a type of mood disorder. It used to be called manic
depression and the term is still often used. If you suffer from bipolar, you go from feeling sad,
hopeless, helpless and worthless (depression) to feeling on top of the world, hyperactive, creative, irritable and grandiose (mania) either very often, or within short periods of time. The disease is called bipolar mood disorder because your mood alternates between opposite poles, namely euphoric happiness and extreme sadness.
