Schizophrenia/Psychosis

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.

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.
