Bipolar disorder is an illness that causes extreme mood changes. It used to be called manic-depressive disorder. A person with bipolar disorder swings between a manic episode and a depressive episode. In a manic episode, they have very high energy and activity. In a depressive episode, they have extreme lows where they feel depressed and have no interest in anything. The timing and intensity of the two episodes varies greatly from person to person.
This illness can be so serious that the person cannot function at work, school, home, or in the community. It is important for that person to know that they are not alone and to talk with others who suffer from bipolar disorder and learn there is hope. Treatment can help them get back in control and feel better.
