Major Depressive Disorder

This article discusses the role of µ-opioid receptors (MORs) in antidepressant treatment and major depressive disorder (MDD). Specifically, it focuses on how the endogenous opioid system affects response to pharmaceuticals.

Since the discovery of dopamine as a neurotransmitter in the late 1950s, schizophrenia has been associated with changes in the dopaminergic system. However, the dopamine hypothesis of schizophrenia cannot explain all the symptoms associated with this disorder. Therefore, research has also focused on the role of other neurotransmitter systems, including glutamate, g-aminobutyric acid, serotonin, and acetylcholine (ACh) in schizophrenia.

The modern era of psychopharmacology is only 60 years old, having begun with the discovery of the psychotherapeutic benefits of reserpine, lithium, monoamine oxidase inhibitors, and chlorpromazine in the late 1940s and early 1950s, which was followed a few years later by the synthesis and testing of the tricyclic antidepressants and benzodiazepines.

An international team of experts recently proposed expanding the diagnostic criteria for several subtypes of bipolar disorder, adding a pediatric bipolar disorder category and eliminating the schizoaffective disorder category.

Why is it that experiencing a new love relationship or coping with a severe crisis has such different outcomes for different persons?

Evidence-based medicine (EBM) is rapidly becoming the norm. It is taught in medical schools and is encouraged by both government agencies and insurance plan providers. Yet, there is little proof that this model can be adapted to fit psychiatry.

In the second century ad, a brilliant physician had a powerful idea: 4 humours, in varied combinations, produced all illness. From that date until the late 19th century, Galen's theory ruled medicine. Its corollary was that the treatment of disease involved getting the humours back in order; releasing them through bloodletting was the most common procedure and was often augmented with other means of freeing bodily fluids (eg, purgatives and laxatives).

Parkinson disease (PD) is a progressive neurodegenerative disorder that is characterized by its motor signs, including resting tremor, rigidity, bradykinesia, and postural instability. PD is more common in the elderly, and there is usually no family history of the disease.

On October 20, 2007, leading researchers in the fields of mood disorders and meditation discussed the promise-and limitations-of meditation for the prevention and treatment of major depression. Participating in a day-long symposium titled "Mindfulness, Compassion, and the Treatment of Depression" was His Holiness the Dalai Lama.

Major depressive disorder (MDD) in pediatric populations represents a significant public health concern. Rates of MDD rise dramatically in adolescence, with an estimated lifetime prevalence of 15% in adolescents aged 15 to 18.

Concern about the rising number of preschool-age children receiving atypical antipsychotics, α-agonists, or other psychotherapeutic medications recently motivated pediatric mental health professionals to develop best-practice algorithms for psycho-pharmacological treatment of young children. It also prompted some states and mental health providers to initiate medication monitoring and consultation programs.

Reading crystal balls has always been difficult. Nevertheless, it may be a worthwhile exercise to stop and make some educated guesses about where the field of psychopharmacology will stand 10 years from now--knowing full well that insights and discoveries we cannot predict or anticipate now may pop up to dramatically change the course and direction of clinical psychopharmacology.

Anxiety disorders are the most prevalent disorders among children and adolescents in both community and clinical settings. The high prevalence of anxiety disorders in children and adolescents leads to increased interest in the development and implementation of effective treatments.

The FDA recently approved the use of aripiprazole (Abilify) in combination with antidepressant medication for the treatment of major depression in adults. Although a variety of agents have been used in efforts to augment the effect of antidepressants, this first approved adjunct is likely to increase this use of atypical antipsychotics.

For many years, research on mood disorders has focused on neurotransmitters, particularly on the monoamines (serotonin, norepinephrine, and dopamine) and their action at the neuronal junction, or synapse. Although the monoamine theory helps explain the action of tricyclics, monoamine oxidase inhibitors, and SSRIs, it fails to account for many other things.

Both cognitive-behavioral and pharmacological treatments for panic disorder have been found to be effective over the short term. Not all patients, however, can tolerate or fully respond to these approaches, and the effectiveness of these interventions over the long term remains unclear.

It is my great honor and pleasure as a psychiatric educator to teach many excellent medical students and residents. These young and not-so-young men and women are by and large diligent, highly professional, and caring.

A Public Health Approach to Intervening With Youth in Schools

Evidence for Use of Neurostimulating Techniques

Public concern about the use of anabolic androgenic steroids by athletes and others has led to enhanced testing for these drugs as well as an improved understanding of their medical and psychiatric effects. This article reviews the pharmacology of these compounds, the prevalence and effects of their use among athletes, and the basics of steroid testing, and it concludes with treatment recommendations. Even though athletes may use other illicit substances, such as stimulants, human growth hormone, and erythropoietin, this article focuses only on anabolic androgenic steroids. Review articles on the psychiatric effects of the other performance-enhancing substances are available elsewhere.1,2

A recent longitudinal study examined the potential relationship between social anxiety disorder during adolescence and young adulthood and the subsequent development of depression.1

From 1826 to 1827, the great philosopher and political scientist John Stuart Mill was stricken with a devastating bout of depression. Although the genesis of his affliction is far from clear, Mill was able to find a fitting description of his mood in Coleridge's poem, "Dejection": A grief without a pang, void, dark, and drear; A stifled, drowsy, unimpassioned grief Which finds no natural outlet, no relief In word, or sigh, or tear.1

Comorbidity of psychiatric syndromes is quite common-in a 12-month period, almost 50% of adults in the United States with any psychiatric disorder had 2 or more disorders.

She was 57 years old, widowed with 2 grown children, and was being evaluated as an aspirant for the Episcopal diaconate. An open, warm, and articulate woman, she described the major turning point in her life as her husband's sudden cardiac death when he was 42 and she was 37. "It came out of the blue," she said. "One moment he was here and the next moment he was gone."
