It generally is a cyclical illness, so while most patients recover from their first depressive episode, the relapse rate is high—possibly as high as 60% inside two years and 75% inside 10 years. After 15 years, 90% of victims will experience a relapse or remission of depression.
Major depression, which affects greater than 16% of U.S. adults sooner or later of their lives, often occurs spontaneously and seemingly for no reason, or begins as a depressive response following a loss, trauma, or other major stressful event. In people who find themselves biologically vulnerable to developing a depressive illness, the initial depressive response may intensify and progress to a clinically full-blown depressive episode. The depressive episode may additionally resolve spontaneously, normally inside six to 12 months, although medications in addition to other types of treatment are sometimes obligatory to bring symptoms fully under control.
