Towards achieving remission in the treatment of depression

The burden of depressive illness constitutes a major public health issue. Despite real progress and better tolerance of new antidepressant medications, a significant number of depressed patients still suffer from rather severe residual depressive symptoms.This relative lack of efficacy clearly interferes with their psychosocial functioning and their quality of life. In addition, it is now well-recognized that the failure to reach full clinical remission after antidepressant treatment involves a high risk of relapse or recurrence in patients suffering from major depression. This paper reviews the concept of remission across different definitions, and the potential risk factors associated with the failure to reach clinical remission. The identification of specific residual symptoms in nonremitted patients is also of great importance, in order to assess the predictive value of those symptoms in relation to relapse and recurrence. Some methodological issues are also discussed, as well as various therapeutic strategies aimed at relieving residual depressive symptoms. Clinical remission remains a qold standard and a primary objective of modem antidepressant therapy.
