A new study comparing the benefits of second-generation antipsychotics (SGAs) with their older counterparts in patients with schizophrenia has yielded a surprising result. The study, funded by the UK National Health Service, found that the overall differences between first- and second-generation antipsychotics did not reach statistical significance.

Bipolar disorder is often seen as a perplexing illness by patients and clinicians alike. In recent years, there has been a growing appreciation in psychiatric circles of the disorder's prevalence. This increased attention has filtered its way down to the general public, which, in turn, has produced sometimes sensationalistic media portrayals of manic depression, a number of speculative books about historic figures and noted artists who purportedly had the illness, and an array of self-help books marketed to individuals (and their families) afflicted with the disorder.

Patients with a serious mental illness (SMI), such as schizophrenia or bipolar disorder, may underreport co-occurring medical conditions. Dr Amy Kilbourne and colleagues performed a cross-sectional analysis of 35,857 patients from the Department of Veterans Affairs (VA) National Registry to determine whether SMI patients were less likely to report a co-occurring medical condition. Results were published in the August 2006 issue of The Journal of Nervous and Mental Disease.

Analyzing data gathered in a 10-nation study of psychoses by the World Health Organization (WHO), Susser and Wanderling1 found that the incidence of nonaffective psychoses with acute onset and full recovery was about 10 times higher in premodern cultures than in modern cultures. Transient psychoses with full recovery were comparatively rare in modern cultures. Such a dramatic difference begs for explanation.

Mostly because of increased speed and decreased costs of communication and transportation, cities are growing increasingly diverse in their population. Consequently, cultural factors have taken center stage in the understanding of urban mental health. This article will focus on the main approaches to urban mental health and briefly summarize the 3 lines of research in this area. It will then discuss the main themes of a vast body of literature on the cultural aspects of urban mental health.

In a recent article on genetic counseling in psychiatry, Christine Finn, MD, and Jordan W. Smoller, MD, ScD, noted that family and twin studies have documented the familiality and heritability of schizophrenia, bipolar disorder, major depression, anxiety disorders, autism, attention-deficit/hyper- activity disorder (ADHD), and Tourette syndrome, among others, and that molecular genetic studies have begun to identify possible susceptibility loci for several of these disorders, most notably schizophrenia.

It may come as a surprise, especially given its low repute in the popular mind since the 1980s, but electroconvulsive therapy (ECT) is making a comeback, both as a recommended treatment for depression and in public awareness.

Initial studies-such as the stepped collaborative care intervention, Texas Medication Algorithm Project (TMAP), and German Algorithm Project (GAP) phase 2-predominantly investigated whether following an expert opinion–based clinical algorithm (irrespective of the content of the algorithm) led to a better outcome than treatment as usual did

In 1931, Gananath Sen and Kartick Chandra Bose reported on the use of an alkaloid extract from the Rauwolfia serpentina plant in the treatment of hypertension and "insanity with violent maniacal symptoms." They noted that dosages "of 20 to 30 grains of the powder twice daily produce not only a hypnotic effect but also a reduction of blood pressure and violent symptoms

Hundreds of uniquely adapted venomous marine cone snail species inhabit the coral reefs of the Indian and Pacific oceans. Researchers posit that each may be a virtual neurologic pharmacopoeia with potential value for the treatment of everything from diabetic neuropathy to schizophrenia. The venoms, known as conotoxins, selectively inhibit a wide range of ion channels involved in neuromuscular signaling.

The editors of Pediatric Neuropsychiatry must have drawn on their experiences and the feedback they received on their first book, Textbook of Pediatric Neuropsychiatry (American Psychiatric Press, 1998), for this text.

The need for better tools, as well as better use of existing tools, to measure treatment response in clinical trials was a principle focus of the 46th annual NIMH-sponsored NCDEU (New Clinical Drug Evaluation Unit) meeting, held June 12-15 in Boca Raton, Fla. Improved clinical research techniques are needed to better separate treatment effect from placebo response, to distinguish between active comparators, and to facilitate development of novel treatments, according to several presenters at the conference.

In its latest report on medication errors, a committee assembled by the Institute of Medicine (IOM) included some sidebars on psychiatric drugs. The report, issued in July, said that there is too little data on misadministration of psychiatric drugs and that clinical trials with psychiatric drugs have been small and incapable of providing pragmatic, comparative information.

Ampakines, agents that have been shown to enhance memory, appear to trigger endogenous brain-derived neurotrophic factor (BDNF), a natural mechanism in the brain that could restore neuronal viability and synaptic plasticity through increased trophic support.
