Major Depressive Disorder

For both depression and anxiety disorders in youths, there is increasing evidence of clinical benefit from cognitive-behavioral therapy (CBT).

Obesity has emerged as a significant threat to public health throughout the developed world. The World Health Organization defines overweight as a body mass index of 25.0 to 29.9 kg/m2 and obesity as a BMI of 30.0 kg/m2 or greater.1 Nearly two-thirds of Americans are overweight or obese according to these criteria.2 Numerous health problems, including diabetes, cardiovascular disease, arthritis, and cancer, are associated with obesity. In addition, overweight and obese persons are more likely than their normal-weight peers to have a variety of psychiatric disorders.

New compounds and novel applications for established products were evaluated in many of the clinical trials reported at the recent 49th annual NIMH-sponsored New Clinical Drugs Evaluation Unit meeting.

Low levels of 3-methoxy-4-hydroxyphenylglycol (MHPG) in patients with major depressive disorder (MDD) or bipolar depression were shown to be associated with increased risk of suicide attempts. Hanga Galfalvy, PhD, assistant professor of clinical neurobiology at Columbia University and the New York State Psychiatric Institute, New York, and her colleagues found that patients with the lowest levels of MHPG at baseline were more likely to commit highly lethal suicidal acts.

All pregnant women should be screened for bipolar disorder, according to a recent article by Verinder Sharma, MB, BS, professor of psychiatry and obstetrics and gynecology at the University of Western Ontario, London, Ontario, and colleagues. This is because bipolar depression may be misdiagnosed as major depressive disorder in the postpartum period, resulting in delays in appropriate treatment.

More than a thousand articles on mental disorders are published in medical journals each month! Also, clinicians have limited training, time, and inclination to keep up with reading research articles critically on a regular basis. Thus, a disturbing disconnect (for which there are no easy solutions) exists between clinical research and usual clinical practice.

Pediatric bipolar disorder (PBD) is a serious psychiatric illness that impairs children’s emotional, cognitive, and social development. PBD causes severe mood instability that manifests in chronic irritability, episodes of rage, tearfulness, distractibility, grandiosity or inflated self-esteem, hypersexual behavior, a decreased need for sleep, and behavioral activation coupled with poor judgment. While research in this area has accelerated during the past 15 years, there are still significant gaps in knowledge concerning the prevalence, etiology, phenomenology, assessment, and treatment for PBD.

There has been much recent attention to the deleterious effects of natural disasters and war on children and adolescents.

The NIMH-sponsored New Clinical Drugs Evaluation Unit (NCDEU) meeting is a favored venue for reports and reviews of NIH-funded psychopharmacological studies, and this was true of the recent annual meeting in Hollywood, Fla. The meeting included a workshop on new investigations of antidepressant use in Alzheimer disease and a panel session on the safety of pharmacotherapy in older adults.

Repetitive transcranial magnetic stimulation (rTMS) may be an effective therapy for treatment-resistant bipolar depression, according to the results of a recent pilot study led by Guohua Xia, MD, PhD, assistant clinical professor of psychiatry at the University of California, Davis.

Major depressive disorder is common during childbearing. Depression that interferes with function develops in an estimated 14.5% of pregnant women. Some statistics are troubling in that only 13.8% of pregnant women who screen positive for depression actually receive treatment.

With billions of dollars for electronic health record (EHR) technology purchases hanging in the balance, psychiatrists need to be paying attention to the Department of Health and Human Services (HHS) deliberations on the definition of “meaningful use.”

The editors of Psychiatric Times interview Vladimir Maletic, MD, PA, clinical professor of neuropsychiatry and behavioral science at the University of South Carolina School of Medicine, Columbia; founding member of the Integrative Neurobiology Educational Alliance; and member of the U.S. Psychiatric and Mental Health Congress 2009 advisory board.

The prevalence of depression in children and adolescents ranges from 2% to 8% in the general population, which indicates that depression in this population is a major public health concern.1-3 This is especially apparent when rates of depression are compared with other serious medical conditions in childhood, such as diabetes, which has a prevalence of 0.18%.4 The burden of depressive illness-including significant functional impairment in interpersonal relationships, school, and work-on the developing child has been well documented. Affected youths are frequently involved in the juvenile justice system.5-8 Furthermore, adolescents with depression are at increased risk for substance abuse, recurrent depression in adulthood, and attempted or completed suicide.3,9-15

Since the time of Homer, warriors have returned from battle with wounds both physical and psychological, and healers from priests to physicians have tried to relieve the pain of injured bodies and tormented minds.1 The soldier’s heartache of the American Civil War and the shell shock of World War I both describe the human toll of combat that since Vietnam has been clinically recognized as posttraumatic stress disorder (PTSD).2 The veterans of Operation Iraqi Freedom (OIF) and of Operation Enduring Freedom (OEF) share with their brothers and sisters in arms the high cost of war. As of August 2009, there have been 4333 confirmed deaths of US service men and women and 31,156 wounded in Iraq. As of this writing, 796 US soldiers have died in the fighting in Afghanistan.3

Restless legs syndrome (RLS) is a neurosensory disorder first described by Sir Thomas Willis in 1672. As early as the 19th century, Theodor Wittmaack observed the comorbidity of RLS with depression and anxiety. He termed this condition “anxietas tibiarum” and believed it to be a form of hysteria.

The validity of any study involves the sequential assessment of confounding bias, followed by chance, followed by causation.

In our last installment, we discussed a familiar finding from the National Comorbidity Survey Replication (NCS-R): the peak age of onset for any mental health disorder is about 14 years. In an attempt to explain these data, we are exploring some of the known developmental changes in the teenaged brain at the level of gene, cell, and behavior.

Self-administration of drugs of abuse often causes changes in the brain that potentiate the development or intensification of addiction. However, an addictive disorder does not develop in every person who uses alcohol or abuses an illicit drug. Whether exposure to a substance of abuse leads to addiction depends on the antecedent properties of the brain.

>I greatly enjoyed Dr Ron Pies’ editorial “What Should Count as a Mental Disorder in DSM-V?”1 in which he encouraged framers of DSM-V to critically examine the boundaries of mental illness and to more carefully distinguish between diseases, disorders, and syndromes. As I have noted elsewhere, current plans to integrate a “spectrum” approach into DSM-V require a careful consideration of these issues that must be defensible to critics of diagnostic expansion within psychiatry.2

What the New Mind-Body Science Tells Us About the Pathophysiology of Major Depression-Focus on Treatment

Historically, borderline patients were considered “help-rejecting complainers.” Clinicians should actively treat both mood/anxiety symptoms and BPD symptoms.

The articles in this Special Report reflect the growing recognition of the importance of the problem of treatment-resistant psychiatric disorders.

There is currently a small but impressive evidence base that shows that psychological and interpersonal factors play a pivotal role in pharmacological treatment responsiveness.

The chances for full recovery from major depressive disorder diminish the longer a patient remains depressed-a fact that lends a sense of urgency for appropriate therapy.

Since the inclusion of the borderline personality disorder (BPD) diagnosis in DSM, there have been multiple efforts to recast the disorder as part of an Axis I illness category. While the initial focus was on the schizophrenia spectrum, more recent authors have attempted to link BPD to mood disorders.

Many refugees have been victims of severe violence that has profoundly affected their physical, psychological, and spiritual lives.

Currently the Veterans Administration (VA) is the world’s largest recipient of per patient funding for PTSD. The VA treats 200,000 veterans with this diagnosis annually at a cost of $4 billion. But research calls into question the very existence of the “PTSD” syndrome, and its diagnostic formulation remains invalid. We do not minimize the suffering of those who experience trauma or the need for comfort and restitution. We seek only to reexamine research evidence, to clarify the impact of culture on diagnosis, to reevaluate the consequences of trauma, and to ensure optimal allocation of resources.

As we begin this brief review of the neurobiology of major depressive disorder (MDD), we face these fundamental questions

Four recent studies have shed light on the effects of early childhood mood and behavioral problems on adulthood.
