Depression is one of the most common mental illnesses in the United States. In the U.S., 21 million adults , or 8.4% of the population, experienced at least one major depressive episode in the last year.1 Depression is both a disorder itself as well as a symptom of other disorders. Some people experience only depression, while others experience depression alongside other symptoms.
Additionally, there are different types of depression, and the magnitude of the diagnosis ranges from person to person. For example, some people experience only one intense depressive episode, while others live with chronic depression that significantly affects their quality of life. What are the different types of depression, some signs and symptoms, and how can you find help?
What is Unipolar Depression?
Unipolar depression is another term that describes major depressive disorder, also called clinical depression. Major depression is the most common form of depression and affects millions of people in the United States every year.2 Unipolar depression symptoms range from mild to severe.

What is Bipolar Depression?
Bipolar disorder is a condition that causes severe shifts in mood, activity, and energy levels. It consists of two primary mood states, or “episodes,”: manic episodes and depressive episodes. Bipolar depression refers to depressive episodes that are symptoms of bipolar disorder. These episodes differ from unipolar depression, though, because depressive episodes last for a few weeks before giving way to manic episodes.3
Signs and Symptoms of Bipolar
Signs and symptoms of bipolar depend on the type of episode a person is in. Symptoms of bipolar depression are similar to the unipolar depression symptoms listed above. On the other hand, symptoms of bipolar mania include:
- Feeling extremely high, elated, “up,” irritable, or agitated
- Feeling more active than normal
- Needing less sleep
- Fast-paced, racing thoughts
- Talking quickly about a lot of different ideas
- Inflated sense of confidence or self-importance
- Participating in risky or harmful behaviors, such as compulsive shopping, overeating, having unprotected sex, or excessive drug or alcohol use
