Antidepressants are drugs used for the treatment of major depressive disorder and other conditions, including dysthymia, anxiety disorders, obsessive compulsive disorder, eating disorders, chronic pain, and neuropathic pain and, in some cases, dysmenorrhoea, snoring, migraines, attention-deficit hyperactivity disorder (ADHD), substance abuse and sleep disorders. They can be used alone or in combination with other medications. To establish efficacy, an antidepressant must show that it can produce a therapeutic effect for the condition for which it is taken. An antidepressant should be more efficacious than placebo to justify the risk associated with side effects. Between 30% and 50% of individuals treated with a given antidepressant do not show a response. In clinical studies, approximately one-third of patients achieve a full remission, one-third experience a response and one-third are nonresponders. Partial remission is characterized by the presence of poorly defined residual symptoms. These symptoms typically include depressed mood, psychic anxiety, sleep disturbance, fatigue and diminished interest or pleasure. It is currently unclear which factors predict partial remission. The therapeutic effects of antidepressants typically do not continue once the course of medication ends, resulting in a high rate of relapse. Controversy regarding the efficacy of antidepressants has arisen due to studies showing that antidepressants fail to provide significantly greater efficacy than placebo in some studies.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
