Who develops bipolar disorder?
Anyone can develop bipolar disorder, including children and teens. However, most people with bipolar disorder develop it in their late teen or early adult years. The illness usually lasts a lifetime.
Why does someone develop bipolar disorder?
Doctors do not know what causes bipolar disorder, but several things may contribute to the illness. Family genes may be one factor because bipolar disorder sometimes runs in families. However, it is important to know that just because someone in your family has bipolar disorder, it does not mean other members of the family will have it as well.
Another factor that may lead to bipolar disorder is the brain structure or the brain function of the person with the disorder. Scientists are finding out more about the disorder by studying it. This research may help doctors do a better job of treating people. Also, this research may help doctors to predict whether a person will get bipolar disorder. One day, doctors may be able to prevent the illness in some people.
What are the symptoms of bipolar disorder?
Bipolar “mood episodes” include unusual mood changes along with unusual sleep habits, activity levels, thoughts, or behavior. In a child, these mood and activity changes must be very different from their usual behavior and from the behavior of other children. A person with bipolar disorder may have manic episodes, depressive episodes, or “mixed” episodes. A mixed episode has both manic and depressive symptoms. These mood episodes cause symptoms that last a week or two or sometimes longer. During an episode, the symptoms last every day for most of the day.
Children and teens having a manic episode may:
- Feel very happy or act silly in a way that’s unusual for them and for other people their age
- Have a very short temper
- Talk really fast about a lot of different things
- Have trouble sleeping but not feel tired
- Have trouble staying focused
- Talk and think about sex more often
- Do risky things
