Depression

Depression is primarily a mood disorder, but it can also be viewed as a cognitive disorder for many older adults.

Although the Washington Report used the term "postabortion depression," this is a term to which the APA objected. There is no credible scientific evidence for such a diagnostic category or for a causal relationship between abortion and mental illness.

Early relapse is a limiting defect in electroconvulsive therapy (ECT). Although more than 80% of patients with a severe depressive illness who complete an acute course of ECT are relieved within three weeks, up to 60% relapse within six months, despite continuation treatments with antidepressant medications.1,2 In a large, government-supported, collaborative study led by the Columbia University Consortium (CUC), patients with unipolar major depression that had failed to respond to multiple trials of medications were treated with ECT to clinical remission and then randomly assigned to one of three continuation treatments--placebo, nortriptyline (Aventyl, Pamelor) alone, or the combination of nortriptyline and lithium (Eskalith, Lithobid). The patients were monitored for adequacy of blood levels.1 Within the six-month follow-up period, 84% of patients treated with placebo, 60% of patients treated with nortriptyline, and 39% of patients treated with the combination medications had relapsed.

Bone mineral density (BMD) was reduced at a greater rate in older women when they had symptoms of depression, according to one recent report from the Study of Osteoporotic Fractures Research Group, while another report implicated treatment with SSRI antidepressants.

The Treatment for Adolescents With Depression Study (TADS) represents the single largest and potentially most informative clinical trial of adolescents with depressive illness. The overall aim of the study was to investigate the effectiveness of standard interventions for adolescent outpatients with moderate to severe depression.

Major depression is at once simple and complex. At one level, the treatment of this disorder is straightforward. Yet, at a multitude of other levels, it is a complex condition for which available treatments remain suboptimal.

If clinical trials data are any indication, the potential impact of placebo treatment on depression outcomes may be potent. Placebo response rates in clinical trials for depression average approximately 30%, with a top range beyond 50%-and the trend is upward.

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.

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.

Adherence, in a medical context, refers to the degree to which a patient follows the treatment plan that has been agreed on between the prescriber (usually, but not always, a physician) and the patient.

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.

Major depressive disorder (MDD) affects a large proportion of the world's population, but much still needs to be done to categorically improve the lives of people with this condition.

Treatment-resistant unipolar major depression appears to be the rule rather than the exception. This view is supported by data from the STAR*D program, a multilevel treatment trial for major depression.

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.

Response to SSRIs, the most frequently used first-line agents for major depression, tends to be slow, and full remission is obtained by fewer than half of treated patients.

In what was billed as the first randomized controlled study to simultaneously evaluate antidepressant therapy and short-term psychotherapy for depressed patients with coronary artery disease (CAD), treatment with an SSRI led to significant improvement, while addition of interpersonal psychotherapy provided no added benefit.

Asthma is one of the most impairing diseases of childhood, affecting more than 6% of children. Each year, it is responsible for 14 million lost school days and $3 billion in treatment costs.

Compared with schizophrenia, adherence behavior has been relatively overlooked in depression and other mood disorders. Major depression is increasingly thought of as a chronic illness. In most chronic illnesses, ideal concordance is the exception, not the rule.

Although treatment-resistant depression is defined in terms of a person's depression being resistant to medication, it usually also means that the patient has been unresponsive to whatever psychotherapy has been tried along the way. What might not be clear from the above but is known by all clinicians is that patients with TRD experience much internal suffering and misery.

Treatment interventions via telephone, Internet, and through other telemedical services are gaining popularity, especially in rural areas where licensed clinicians might not be available. Dr Per Carlbring and colleagues recently evaluated a 10-week, Internet-based, self-help program with weekly telephone calls for patients who had panic disorder with or without agoraphobia. The results were published in the December 2006 issue of the American Journal of Psychiatry.

I was disappointed to see the Figure titled Olanzapine and fluoxetine in the treatment of TRD in the article Treatment-Resistant Depression: Strategies for Management" ( Psychiatric Times, page 34) in the October 2006 special bonus edition.

The construct of bipolar spectrum disorder remains a work in progress. Its precise boundaries are still a matter of considerable debate. Some psychiatrists are convinced that it is widely overdiagnosed. It is possible that depending on the clinician and the clinical setting both views are correct.

Despite the clinician's goal of treating the depressed patient to the point of remission, this state is generally achieved in only 15% to 30% of patients. Another 10% to 30% of patients respond poorly to antidepressant treatment, while 30% to 40% have a remitting and relapsing course.1 Patients without a major depressive disorder are likely to be treated successfully by primary care physicians and/or other mental health professionals, which leaves psychiatrists to treat patients who have forms of depression that are less responsive to treatment.

Although suicidal ideation occurs in roughly 5% to 14% of pregnancies,1 suicide attempts are relatively rare (0.04%) and are associated with substance abuse and poor pregnancy outcome.2 After a suicide attempt, the clinician must first consider the possibility of recurrence of self-destructive behavior by assessing the woman's motivation, her attitude toward the pregnancy, and the severity of her depressive symptoms.
