Schizophrenia/Psychosis

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.

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).

The brutal murder of New York psychologist Kathryn Faughey and attempted murder of psychiatrist Kent Shinbach this past February has provoked warnings to psychiatrists about personal safety and overreliance on clinical judgment. David Tarloff, a person with schizophrenia, was indicted for the attacks. According to press reports, Tarloff blamed Shinbach for having him institutionalized in 1991. While he was wait-ing to see Shinbach, Tarloff allegedly entered Faughey's nearby office and slashed her to death with a meat cleaver and knives. Shinbach heard her screams, tried to rescue her, and was assaulted and robbed.

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.

The mind-brain dichotomy has been on a roller-coaster ride over the past few hundred years. Clinically astute European neuropsychiatrists in the 18th and 19th centuries described various neuropsychiatric disorders based on observations of their patients.

Psychiatry has gone wrong by being too symptom-focused, too brain-oriented, and riddled with misdiagnoses. It should go back to seeking the "meaning" of things in patients' subjective experiences. This is the main theme of this short polemic based on case studies. The author selectively cites studies or opinions to make his point rather than trying to get at the truth by offering other perspectives. As George Orwell pointed out, books are of 2 types: those that seek to justify an opinion and those that seek the truth.

Prognostication is a major part of what physicians do in many fields of medicine, and it is particularly relevant when a treatment or procedure is controversial or anxiety-provoking. Being able to accurately tell a prospective ECT patient how likely he or she is to respond would be helpful.

Psychiatry has seen a transition from art to science in the past century and, largely because of 2 developments in the past several decades, this has also been the case for the field of eating disorders.

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 vesicular monoamine transporter (VMAT) is a membrane-embedded protein that transports monoamine neurotransmitter molecules into intraneuronal storage vesicles to allow subsequent release into the synapse.1,2 By accumulating both newly synthesized neurotransmitter molecules and freshly returned neurotransmitter molecules from the synapse, VMAT function plays a critical role in the signaling process between monoamine neurons. The VMAT exists in 2 distinct forms: VMAT1 and VMAT2.3

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.

The expression "quality of life" is an intuitively familiar and popular concept, and it epitomizes the public's hopes and expectations. In clinical settings, it demands the inclusion of patients' feelings, attitudes, and opinions in medical decision making.

Vietnamese Amerasians and the former political prisoners of South Vietnam are living legacies of the Vietnam War. Now that many live in the United States, it is important for psychiatrists to have an understanding of their life experiences and be able to recognize psychiatric disorders that are common among them.

Suicide is a devastating, tragically frequent outcome for persons with varying psychiatric conditions, including schizophrenia. An estimated 5% to 10% of persons with schizophrenia commit suicide and 20% to 50% attempt suicide during their lifetime.1,2 Patients with schizophrenia have more than an 8-fold increased risk of completing suicide (based on the standardized mortality ratio) than the general population.3

The 1994 death of Nicole Brown Simpson and the subsequent highly publicized murder trial of her ex-husband, O.J. Simpson, brought increasing national attention to the problems of domestic violence and intimate partner murder. In 2000, there were 1247 female victims of intimate partner murder in the United States.1 Fully one third of female murder victims were killed by an intimate partner.1 On the positive side, rates of female victimization by intimate partner violence and murder appear to have decreased in the recent past.

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.

Recently, a number of studies have examined the characteristics of early-onset schizophrenia spectrum disorders and medication treatment for youths with schizophrenia.

The Supreme Court's 2006 decision in Clark v Arizona1 was one of the most unexpected defeats the American Psychiatric Association (APA) has had since it began regularly submitting amicus briefs to the Court 35 years ago.

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).

In 2006, substance dependence or abuse was diagnosed in about 22.6 million persons in the United States.1 Addiction-related morbidity and mortality pose a major burden to society, costing our economy more than $500 billion annually: about $181 billion for illicit drugs,2 $168 billion for tobacco,3 and $185 billion for alcohol.4

New research is examining the link between schizophrenia/psychosis and select infections affecting the CNS. Two reports investigated this link in children and military personnel in the January 2008 issue of the American Journal of Psychiatry.

It is a pleasure to introduce this series of 4 special articles on schizophrenia. As industry support has shaped postgraduate psychiatric education, the quantity of educational programs has grown dramatically while the breadth of topics has not.

Each year more than 440,000 people in the United States die of smoking-related illness, and nearly half a billion dollars in health-related economic losses are directly attributable to smoking.

In recent years, we have learned a great deal about posttraumatic stress disorder (PTSD) and its public health implications. From 9/11 to Katrina and the present Iraq war, PTSD has been in the forefront of health concerns and public policy.

Extensive evidence supports the importance of the involvement of families in the mental health care of patients with schizophrenia and other serious mental illnesses. Family involvement is endorsed by the President's New Freedom Commission and the American Psychiatric Association Practice Guidelines on schizophrenia.

The number of prescriptions for antipsychotic treatment of teenagers has increased sharply in office-based medical practice. Adolescents with psychotic symptoms frequently present for clinical evaluation, and early-onset schizophrenia spectrum disorders (onset of psychotic symptoms before the age of 18 years) represent an important consideration in the differential diagnosis in these youths

Treatment of negative symptoms of schizophrenia -- eg, problems with motivation, social withdrawal, diminished affective responsiveness, speech, and movement -- is associated with a variety of improved functional outcomes and is a vital unmet clinical need.

Congress substituted a 0.5% increase in Medicare fees for the first 6 months of 2008 for the 10% reduction that would otherwise have been enacted. That reduction in what is called the Medicare fee "update" was predetermined by a formula Congress itself put in place.
