Mood disorders are among the most prevalent forms of mental illness. Serious depression is especially common; based on a face-to-face survey conducted from December 2001 to December 2002, the past-year prevalence rate of clinically significant major depressive disorder (MDD) was estimated to be 6.6%, affecting at least 13.1 to 14.2 million Americans.

Mood disorders are common in women and typically emerge during the childbearing years. While pregnancy has traditionally been considered a time of emotional well- being, recent data indicate that about 10% to 15% of women experience clinically significant depressive symptoms during pregnancy.

In this article, we use the example of major depressive disorder (MDD) to review research efforts to identify predictors of treatment response, both to antidepressant medications and to psychotherapy. We describe the promises and limitations of this research, with some emphasis on brain imaging studies, and then discuss how this work may be integrated into clinical practice in the future.

In lecturing to medical students, residents, and psychiatrists during the past several years, we have encountered widespread hesitancy in the use of MAOIs and even TCAs, mainly because of concerns about their safety but also because of doubts about their effectiveness compared with newer alternatives. Thus, it is timely to review the literature on the efficacy and safety of TCAs and MAOIs, with a view to maintaining an appropriate place for these 2 drug classes in the pharmacotherapy of depression.

Although cognitive therapy (CT) is the best-studied form of psychotherapy, its effectivenes compared with antidepressant medication remains controversial. Over the years, there has been some variability in the results of randomized controlled trials and other types of clinical trials, as well as meta-analyses.

Like medicine in general, psychiatry and psychotherapy have long focused on relieving illness and pain. Traditional psychotherapeutic approaches have often emphasized examination and understanding of painful experiences as a route toward obtaining relief from suffering.

This May, the FDA called for a black box warning on antidepressants to indicate that patients aged 18 to 24 years are at heightened risk for treatment-emergent suicidality. But a member of the FDA advisory committee that recommended that warning has issued his own warning, saying that the "real killer in this story is untreated depression and the possible risk from antidepressant treatment is dwarfed by that from the disease."

Democratic control of Congress may result in the dislodging of a long-stuck bill authorizing an unspecified amount of additional federal funding for research into postpartum depression. But in hearings in a House subcommittee recently, Republicans voiced an intention to add postabortion depression to the bill's focus.

Figures from the US Department of Justice indicate that more than half of prison and jail inmates have a mental health problem. Mental health courts (MHCs) were designed to divert mentally ill persons convicted of nonviolent crimes to supervised treatment instead of incarceration, but while the number of MHCs has grown substantially over the past decade, limited information has been available about outcomes and costs.

Traumatic experiences are linked with a continuum of mental disorders and physical complaints. In the United States, posttraumatic stress disorder (PTSD) occurs in approximately 8% of adults during their lifetime, with different trauma types associated with varying rates of illness. PTSD is commonly associated with comorbid mental conditions such as depressive disorders, other anxiety disorders, impulse control disorders, and alcohol abuse.
