A mood disorder primarily affects a person’s emotional state. It is a mental health problem in which a person experiences long periods of extreme happiness, extreme sadness, or both.
It is normal for someone’s mood to change, depending on the situation. However, to be diagnosed with a mood disorder, symptoms must be present for several weeks or longer. Mood disorders can cause changes in your behavior and can affect your ability to deal with routine activities, such as work or school.
