Effective Treatments Are Available Depression is more than the blues. Depression is not a personal weakness. Depression is a treatable illness. Without treatment, the symptoms can last for months, years, or a lifetime.
Some depressive episodes occur suddenly for no apparent reason.
A good diagnosis involves a complete physical checkup and family history of health problems. Symptoms can be relieved, usually in a matter of weeks. In severe depression, medication is usually required. People with severe depression respond more rapidly and more consistently to medication. Those with recurring depression, including bipolar disorder, may need to stay on medication to prevent or lessen further episodes.
