Symptoms can range from mild to the more severe cases that affect social, school and home life.

Bipolar Disorder Look for these signs and symptoms:
Bipolar disorder, also known as manic-depressive illness, is a medical illness that causes shifts in a person's mood, energy, and ability to function. Different from the normal ups and downs that everyone experiences, the symptoms of bipolar disorder are severe.

Bipolar disorder causes dramatic mood swings from overly "high," and/or irritable to sad and hopeless, and then back again, often with periods of normal mood in between. Severe changes in energy and behavior go along with these changes in mood. The periods of highs and lows are called episodes of mania and depression.

Dysthymic disorder is characterized by “bad mood.” It is different from major depressive disorder in that it is a low-grade depressive syndrome that persists over a period of many months, sometimes for years. It can remain undetected for a long time. The symptoms are not as dramatic as major depressive disorder, but it can be just as dangerous. Dysthymic disorder has been diagnosed in children as young as 5.
