Does your teen go through extreme changes in mood and behavior?
Does your teen get much more excited or much more irritable than other kids? Do you notice that your teen goes through cycles of extreme highs and lows more often than other children? Do these mood changes affect how your child acts at school or at home?
Some children and teens with these symptoms may have bipolar disorder, a brain disorder that causes unusual shifts in mood, energy, activity levels, and day-to-day functioning. With treatment, children and teens with bipolar disorder can get better over time.
What is bipolar disorder?
Bipolar disorder is a mental disorder that causes people to experience noticeable, sometimes extreme, changes in mood and behavior. Sometimes children with bipolar disorder feel very happy or “up” and are much more energetic and active than usual. This is called a manic episode. Sometimes children with bipolar disorder feel very sad or “down” and are much less active than usual. This is called a depressive episode.
Bipolar disorder, which used to be called manic-depressive illness or manic depression, is not the same as the normal ups and downs every child goes through. The mood changes in bipolar disorder are more extreme, often unprovoked, and accompanied by changes in sleep, energy level, and the ability to think clearly. Bipolar symptoms can make it hard for young people to perform well in school or to get along with friends and family members. Some children and teens with bipolar disorder may try to hurt themselves or attempt suicide.
Most people are diagnosed with bipolar disorder in adolescence or adulthood, but the symptoms can appear earlier in childhood. Bipolar disorder is often episodic, but it usually lasts a lifetime.
Signs and symptoms of bipolar disorder may overlap with symptoms of other disorders that are common in young people, such as attention-deficit/hyperactivity disorder (ADHD), conduct problems, major depression, and anxiety disorders. Diagnosing bipolar disorder can be complicated and requires a careful and thorough evaluation by a trained, experienced mental health professional.
With treatment, children and teens with bipolar disorder can manage their symptoms and lead successful lives.
What causes bipolar disorder?
The exact causes of bipolar disorder are unknown, but several factors may contribute to the illness.
For example, researchers are beginning to uncover genetic mechanisms that are linked to bipolar disorder and other mental disorders. Research shows that people’s chance of having bipolar disorder is higher if they have a close family member with the illness, which may be because they have the same genetic variations. However, just because one family member has bipolar disorder, it does not mean that other members of the family will have it. Many genes are involved in the disorder, and no single gene causes it.
Research also suggests that adversity, trauma, and stressful life events may increase the chances of developing bipolar disorder in people with a genetic risk of having the illness.
Some research studies have found differences in brain structure and function between people who have bipolar disorder and those who do not. Researchers are studying the disorder to learn more about its causes and effective treatments.
What are the symptoms of bipolar disorder?
Mood episodes in bipolar disorder include intense emotions along with significant changes in sleep habits, activity levels, thoughts, or behaviors. 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 often last for several days or weeks. During an episode, the symptoms last every day for most of the day.
These mood and activity changes are very different from the child’s usual behavior and from the behavior of healthy children and teens.
Children and teens having a manic episode may:
- Show intense happiness or silliness for long periods of time.
- Have a very short temper or seem extremely irritable.
- Talk fast about a lot of different things.
- Have trouble sleeping but not feel tired.
- Have trouble staying focused, and experience racing thoughts.
- Seem overly interested or involved in pleasurable but risky activities.
- Do risky or reckless things that show poor judgment.
Children and teens having a depressive episode may:
- Feel frequent and unprovoked sadness.
- Show increased irritability, anger, or hostility.
- Complain a lot about pain, such as stomachaches and headaches.
- Have a noticeable increase in amount of sleep.
- Have difficulty concentrating.
- Feel hopeless and worthless.
- Have difficulty communicating or maintaining relationships.
- Eat too much or too little.
- Have little energy and no interest in activities they usually enjoy.
- Think about death, or have thoughts of suicide.
Can children and teens with bipolar disorder have other problems?
Young people with bipolar disorder can have several problems at the same time. These include:
- Misuse of alcohol and drugs. Young people with bipolar disorder are at risk of misusing alcohol or drugs.
- Attention-deficit/hyperactivity disorder (ADHD). Children and teens who have both bipolar disorder and ADHD may have trouble staying focused.
- Anxiety disorders. Children and teens with bipolar disorder also may have an anxiety disorder.
Sometimes extreme behaviors go along with mood episodes. During manic episodes, young people with bipolar disorder may take extreme risks that they wouldn’t usually take or that could cause them harm or injury. During depressive episodes, some young people with bipolar disorder may think about running away from home or have thoughts of suicide.
