Major Depressive Disorder

Here I will discuss several examples of recent, reasonable depictions of ECT in the media, and I will suggest how they could represent a shift in the way that this “controversial” therapy is regarded. I use the word “controversial” advisedly, because even on the day I write this, a newspaper article on deep-brain stimulation, in which ECT is described, reads: “New reports this month show that some worst-case patients-whose depression wasn’t relieved by medication, psychotherapy, or even controversial shock treatment-are finding lasting relief.

This article focuses on recent innovations in diagnostic issues, tactics, and strategy, and takes a brief look at the future.

The fact that treatment with interferon (IFN)-α has become the world’s foremost human model for studying how the innate immune system promotes depression points to a disturbing clinical truth: patients who elect to receive (IFN)-α therapy for any of the several disease states to which it is applied face a high likelihood of experiencing a multitude of psychiatric symptoms severe enough to affect their social and occupational functioning and overall well-being.1

Recent research emphasizes our need for better understanding of the interface between the specialties of psychiatry and medicine. Psychiatrists need to monitor emerging work that highlights the need for both a neuroscientific and medical perspective in the management of complex disorders.

Universal prevention has been a focus of psychiatric research for the past 4 decades. Using a public health approach, research has shown that mitigating major risk factors, such as poverty and early life stress, and promoting protective factors can improve behavioral outcomes.

he key manifestations of DSM-IV somatoform disorder are unexplained physical symptoms or complaints that tend to coexist with other psychiatric syndromes or are linked to psychological issues. These symptoms typically lead to repeated medical or emergency department visits; are associated with serious discomfort, dysfunction, and disability; and lead to significant health expenditures.

Polypharmacy is used increasingly in the treatment of depression.1 Although it can be beneficial-and at times may even be unavoidable-it can also be overused, resulting in drug-drug interactions, accumulation of adverse effects, reduced treatment adherence, and unnecessary increases in the cost of health care.2 This article describes current trends in psychiatric polypharmacy in the treatment of depression along with ways to use polypharmacy to optimize treatment outcomes.

This review provides an overview of the efficacy, safety, and mechanisms of action in the treatment of depression.

While tremendous therapeutic advancements have been made, patients with rheumatoid arthritis (RA) have a myriad of comorbidities, including fatigue, depression, and sleep disturbances. Data on the comorbidity of psychiatric disorders with arthritis are also striking: according to the NIMH Catchment Area program, the lifetime prevalence of psychiatric disorders among patients with RA is 63%.

Depression is a risk factor for cardiovascular disease and death in many ways, directly and indirectly. It is independently linked to smoking, diabetes, and obesity-all of which are risk factors for coronary heart disease (CHD).1 Depressed patients are more likely to be noncompliant with treatment recommendations, including diet, medications, and keeping appointments, and are more likely to delay presentation for treatment with an acute coronary event.2-4

Depression complicates medical illnesses and their management, and it increases health care use, disability, and mortality. This article focuses on the recent research data on diagnosis, etiopathogenesis, treatment, and prevention in unipolar, bipolar, psychotic, and subsyndromal depression.

Contemporary Western psychiatry subsumes diverse perspectives on the so-called mind-body problem, but there is still no consensus on a single best or most complete explanatory model of mind-body interactions. Western psychiatry describes brain function in terms of dynamic properties of neurotransmitters and electromagnetic energy fields.

The rising prevalence and dispersion of obesity in North America in the past decade is analogous to a communicable disease epidemic. Longitudinal and cross-sectional associations between major depressive disorder, schizophrenia, and obesity have been established. Existing evidence also indicates that there is an association between bipolar disorder and obesity.

The loss of a loved one is one of the most traumatic events in a person’s life. In spite of this, most people cope with the loss with minimal morbidity. Approximately 2.5 million people die in the United States every year, and each leaves behind about 5 bereaved people.

Older adults can present with anxiety or worries about physical health (illness, changes in vision or hearing), cognitive difficulties, finances, and changes in life status (widowhood, care-giving responsibilities, retirement). Clinicians need to be aware that older adults may deny psychological symptoms of anxiety (fear, worry) but endorse similar emotions with different words (worries, concerns).

Despite its wretched history, psychosurgery is back with a new name-neurosurgery for mental disorders-and with renewed confidence in its benefits.1 Two technologies are now available that produce small lesions in the brain: stereotactic microablation and gamma knife radiation (no burr holes necessary). Concomitant functional imaging allows for precision targeting that makes these procedures state of the art, but it is possible that deep brain stimulation (DBS), which has shown early promise in clinical trials and is an exciting research tool, may replace ablative procedures that destroy brain cells. Both new stereotactic neurosurgery and old psychosurgery were the focus of recent mass media reports.

In clinical medicine, the term recovery connotes the act of regaining or returning to a normal or usual state of health. However, there is lack of consensus about the use of this term (which may indicate both a process and a state), as well as of the related word remission, which indicates a temporary abatement of symptoms. Such ambiguities also affect the concepts of relapse (the return of a disease after its apparent cessation) and recurrence (the return of symptoms after a remission).

As an intern fulfilling my internal medicine outpatient rotation requirement, I worked in an urgent care walk-in clinic. One afternoon, I entered the waiting room to meet my last patient of the day. He was a 65-year-old white man who was receiving a workup for renal carcinoma.

He was in his early 60s and a master carpenter who had helped build our house in the east Texas piney woods some 20 years ago. When I asked him about his cousin who had helped him with the house, he paused and then said sadly, "Doc, he just lost his spit."

A number of studies have found decreased scores on quality-of-life scales in persons with insomnia, which is associated with a wide assortment of daytime impairments, some intuitive and some startling.

There is substantial comorbidity with oppositional defiant disorder (ODD) and conduct disorder (CD) in children with attention-deficit/hyperactivity disorder (ADHD). It is important to determine the effect of comorbid ODD and CD on the clinical course in youth with ADHD. Biederman and associates1 recently published clinical findings from a 10-year prospective, longitudinal study of boys with ADHD, following them into early adulthood.

Traumatic brain injury (TBI) is the major cause of death and disability among young adults. In spite of preventive measures, the incidence of a TBI associated with motor vehicle accidents, falls, assault, and high-contact sports continues to be alarmingly high and constitutes a major public health concern. In addition, the recent military operations in Iraq and Afghanistan have resulted in a large number of persons with blast injuries and brain trauma. Taking into account that cognitive and behavioral changes have a decisive influence in the recovery and community reintegration of patients with a TBI, there is a renewed interest in developing systematic studies of the frequency, mechanism, and treatment of the psychopathological alterations observed among these patients.

Everyone is unique at the level of social, cultural, psychological, biological, and possibly "energetic" functioning. By extension, in every person, the complex causes or meanings of symptoms are uniquely determined. The diversity and complexity of factors that contribute to mental illness often make it difficult to accurately assess the underlying causes of symptoms and to identify treatments that most effectively address them.

What is the effectiveness (if any) of antidepressants in bipolar depression? What is the risk of manic switching? How effective are antidepressants in preventing relapse of bipolar depression? Insights here.

As psychiatrists we need to clarify within our profession and with our patients what therapies actually treat an illness and what therapies help one learn to function better.
