Diagnoses are currently made on the basis of a constellation of symptoms that include sadness, fatigue, insomnia and suicidal thoughts. The diagnostic manual used by doctors says that anyone who has at least five such symptoms for as little as two weeks may be clinically depressed. Only in the case of someone grieving over the death of a loved one is it normal for symptoms to last as long as two months, the manual says.
The new study, however, found that extended periods of depression-like symptoms are common in people who have been through other life stresses such as a divorce or a natural disaster and that they do not necessarily constitute illness.
The study also suggested that drug treatment may often be inappropriate for people who are experiencing painful -- but normal -- responses to life's stresses. Supportive therapy, on the other hand, may be useful -- and may keep someone who has been through a divorce or has lost a job from going on to develop full-blown depression.
