Mania and hypomania both involve periods when the individual feels excited or experiences an energized mood. They differ in how severe these mood changes are:
- Mania is a severe episode that may last for a week or more. A person may feel uncontrollably elated and very high in energy. These symptoms interfere with daily life, and in severe cases, a person may need to go to the hospital.
- Hypomania is an episode that lasts for a few days. People may feel very good and function well. Family or friends may notice mood or activity changes, while the person with the hypomania may not.
