This page contains the basic information about Major Depression .
On average, untreated episodes last several months. However, episodes of major depression can last any length of time. And symptoms can vary in intensity during an episode.
If depression is not treated, it can become chronic (long-lasting). Treatment can shorten the length and severity of a depressive episode.
