How is bipolar disorder diagnosed?

An experienced doctor will carefully examine your child. There are no blood tests or brain scans that can diagnose bipolar disorder. Instead, the doctor will ask questions about your child's mood and sleeping patterns. The doctor will also ask about your child's energy and behavior. Sometimes doctors need to know about medical problems in your family, such as depression or alcoholism. The doctor may use tests to see if an illness other than bipolar disorder is causing your child's symptoms.
