Youth with bipolar disorder experience unusually intense emotional states that occur in distinct periods called "mood episodes." An overly joyful or overexcited state is called a manic episode, and an extremely sad or hopeless state is called a depressive episode. Sometimes, a mood episode includes symptoms of both mania and depression. This is called a mixed state. People with bipolar disorder also may be explosive and irritable during a mood episode.
Extreme changes in energy, activity, sleep, and behavior go along with these changes in mood. Symptoms of bipolar disorder are described below.

It's normal for almost every child or teen to have some of these symptoms sometimes. These passing changes should not be confused with bipolar disorder.
Symptoms of bipolar disorder are not like the normal changes in mood and energy that everyone has now and then. Bipolar symptoms are more extreme and tend to last for most of the day, nearly every day, for at least one week. Also, depressive or manic episodes include moods very different from a child's normal mood, and the behaviors described in the chart above may start at the same time. Sometimes the symptoms of bipolar disorder are so severe that the child needs to be treated in a hospital.
In addition to mania and depression, bipolar disorder can cause a range of moods, as shown on the scale below. One side of the scale includes severe depression, moderate depression, and mild low mood. Moderate depression may cause less extreme symptoms, and mild low mood is called dysthymia when it is chronic or long-term. In the middle of the scale is normal or balanced mood.
Sometimes, a child may have more energy and be more active than normal, but not show the severe signs of a full-blown manic episode. When this happens, it is called hypomania, and it generally lasts for at least four days in a row. Hypomania causes noticeable changes in behavior, but does not harm a child's ability to function in the way mania does.
