How does major depression happen?

ANSWER

Major depression, which affects more than 16% of U.S. adults, often happens for reasons that aren’t clear, or it can begin as a depressive reaction after a loss, trauma, or other stressful event. For some people, the first depressive reaction can become a full-blown depressive episode. That episode may disappear in 6 to 12 months, though treatment is often needed to control symptoms. Because it can be disabling and can bring a risk of suicide, major depression often needs medical treatment.
