What are mood disorders?

Mood disorders are illnesses that affect the way you think and feel. The symptoms may be quite severe. In most cases, they won't go away on their own. The most common mood disorders are depression and bipolar disorder.

  • Depression. The main symptom of depression is a feeling of deep sadness. You may also feel hopeless. Or that life isn't worth living. At times you may think about suicide or death. Most people have some sadness in their lives. These feelings often lessen with time. But people with severe depression may not get better without treatment.

  • Bipolar disorder. Bipolar disorder is sometimes called manic-depressive illness. That's because it causes extreme mood swings. At times you may feel intensely happy and full of energy. These episodes are often followed by great despair. In some cases, you may have both extremes at once. It’s likely that you'll have phases when your mood shifts back and forth. You may have these mood swings just once in a while. Or they may happen a few times a year. Without treatment, they will likely keep happening for the rest of your life.

What causes mood disorders?

No one knows just what causes affective disorders. It is known they run in families. Changes in certain chemicals in your brain also may play a role. Major life changes, stress, trauma, certain physical illnesses, and medicines can each result in an affective disorder. These disorders affect both men and women. They also may strike people of every age, race, and income level.
