To improve validity, we proposed extending the current MDD bereavement exclusion-which excludes “uncomplicated” (relatively brief, lacking certain severe symptoms) depressive bereavement from diagnosis-to also exclude uncomplicated reactions to other major stressors, such as romantic breakups, job loss, and serious medical diagnoses.

Social anxiety disorder (SAD), also referred to as social phobia, is a chronic and potentially disabling anxiety disorder characterized by the intense and persistent fear of being scrutinized or negatively evaluated by others. At its core, people with this disorder fear and/or avoid the scrutiny of others. Symptoms may occur only in circumscribed situations, such as a fear of speaking in formal or informal situations, or eating or drinking in front of others.

For many antidepressants, the issue of brand-name versus generic has no practical significance. Elavil was first marketed almost a half century ago, and its patent has long expired. It lives on, however, but as generic amitriptyline. Today, only a few antidepressants are still fully protected by patents, namely, Cymbalta (2010), Lexapro (2012), and Pristiq (2022) for major depressive disorder (MDD); and Seroquel (2011) and Symbyax (2017) for bipolar depression.

Lecturing around the country has left us with the powerful impression that both psychiatrists and primary care physicians are hungry for new ways to think about and treat depression and the myriad symptoms and syndromes with which it is associated-including attention deficit disorder, insomnia, chronic pain conditions, substance abuse, and various states of disabling anxiety. Primary care physicians also seem especially excited to learn that depression is not just a psychiatric illness but a behavioral manifestation of underlying pathophysiological processes that promote most of the other conditions they struggle to treat-including cardiovascular disease, diabetes, cancer, and dementia.1,2

Autism spectrum disorders (ASDs) are a group of 5 neuro developmental conditions (autism, Asperger syndrome, pervasive developmental disorder not otherwise specified [PDD-NOS], Rett syndrome, and disintegrative childhood disorder).1 Once thought to be rare, the incidence of these disorders is now estimated to be 1 in 150 children in the general population.2 Furthermore, the number of recognized cases has increased markedly in recent years.

Allegations of suppressed research, promotion of drugs for unapproved uses, payment of kickbacks to physicians, and ghostwriting of a major journal article surfaced recently when the Department of Justice unsealed a civil complaint against Forest Laboratories and Forest Pharmaceuticals, Inc.

Subjective complaints of impaired concentration, memory, and attention are common in people with major depressive disorder (MDD), and research shows that a variety of structural brain abnormalities are associated with MDD.1 These findings have intensified the interest in quantitative assessment of cognitive and neuropsychological performance in patients with mood disorders. Many studies that used standardized cognitive tests have found that mild cognitive abnormalities are associated with MDD and that these abnormalities are more pronounced in persons who have MDD with melancholic or psychotic features

Generalized anxiety disorder (GAD) is a prevalent, chronic, debilitating mental illness associated with marked impairment in daily functioning.1 An ongoing evolution of the definition of GAD has resulted in a bifurcation of the historical anxiety neurosis designation.2 A diagnosis of GAD currently implies chronic, excessive worry lasting at least 6 months and 3 of the possible 6 somatic or psychological symptoms (restlessness, fatigue, muscle tension, irritability, difficulty concentrating, and sleep disturbance).3 GAD typically presents in an episodic pattern of moderate improvement or remission and relapse characterized by a chronic and complicated clinical course.

The cardiovascular properties of serotonin (5-HT) have been known for some time-its name reflects its presence in serum and its action in increasing vascular tone. Serotonergic medications are routinely used to treat depressive and anxiety disorders, and the association of depression with cardiovascular disease has become well established.2 Recent studies have confirmed the colloquial wisdom that anxiety (especially panic) and hypertension are linked.

It has been a relatively short time between clinical use of the term anxiety neurosis-which included worry, panic, and obsessions-and the advent of recent DSM-defined categorical diagnoses of panic disorder, generalized anxiety disorder, social anxiety disorder, posttraumatic stress disorder, and obsessive-compulsive disorder. It seems that we have moved from a symptom-oriented approach in treating anxiety to a syndromal approach in which the patient has to accumulate enough symptoms and impairment to have a more definable illness or disorder.

Does adoption pose psychological risks? University of Minnesota researchers revisited this controversial issue recently and found that common DSM-IV childhood disorders are more prevalent in adoptees than nonadoptees.

Suicide risk assessment is a core competency that all psychiatrists must have.1 A competent suicide assessment identifies modifiable and treatable protective factors that inform patient treatment and safety management.2 Psychiatrists, unlike other medical specialists, do not often experience patient deaths, except by suicide. Patient suicide is an occupational hazard. A clinical axiom holds that there are 2 kinds of psychiatrists: those who have had patients commit suicide-and those who will.

Although most studies have focused on the risk of metabolic syndrome for patients with schizophrenia exposed to atypical antipsychotics, other psychiatric patients appear to be at risk for metabolic disturbances as well.7-9 Major depressive disorder (MDD) may be of particular interest because it is much more common than schizophrenia and is treated with a broad range of psychotropics.

A large percentage of youths use and abuse psychoactive substances. According to the 2007 Monitoring the Future (MTF) survey, the percentage of US adolescents who used illicit drugs or drank alcohol continued a decade-long drop, revealing that 19% of 8th grad­ers, more than 36% of 10th graders, and 47% of all 12th graders have taken an illicit drug (other than alcohol) during their lifetime.1 According to the National Survey on Drug Use and Health, the rate was 3.3% for misuse or nonmedical use of prescription drugs.2 The misuse of prescription drugs among adolescents was second only to marijuana use. In fact, prescription drugs increasingly have become a part of the repertoire of drug-using adolescents.

The substantial and often recurrent distress and impairment associated with major depressive disorder (MDD) in youth has prompted increased interest in the identification and dissemination of effective treatment models. Evidence supports the use of several antidepressant medications, specific psychotherapies, and, in the largest treatment study of depressed teenagers, the combination of fluoxetine and cognitive-behavioral therapy (CBT) as effective treatments.1-3 CBT is the most extensively tested psychosocial treatment for MDD in youth, with evidence from reviews and meta-analyses that supports its effectiveness in that population.3-5
