A team of neuroscientists from Purdue University and Nagoya University in Nagoya, Japan, has identified acrolein as a key neurotoxin in the neurodegenerative process that follows traumatic spinal cord injury. Acrolein, a toxic industrial by-product, naturally occurs in the body in negligible quantities as free radical molecules. However, it can quickly accrue to toxic levels in response to trauma, stress, or exposure to environmental carcinogens. Carriage

Celebrity Triggers Tumult Over Psychiatric Care: Did the News Media Make Things Worse? by Michael Jonathan Grinfeld When Tom Cruise accused Brooke Shields of being irresponsible by taking antidepressants after the birth of her baby, psychiatry was momentarily thrust into the spotlight. How did journalists and scientists handle the situation, and how can they do better in the future?
The Emerging Role of GABAergic Mechanisms in Mood Disorders by Po W. Wang, M.D., and Terence A. Ketter, M.D. Gamma-aminobutyric acid is a major inhibitory neurotransmitter widely distributed in the mammalian central nervous system. Animal models of depression have pointed toward the importance of the GABA system in the pathophysiology of mood disorders. Thus, elucidating the GABAergic effects of benzodiazepines, mood stabilizers, antidepressants, and new anticonvulsants and antipsychotics may expand our understanding of mood disorder pathophysiology and potentially generate new targets for treatment.

Antiepilepsy drug use in children presents special challenges because, unlike adults, treatment-emergent neuropsychological deficits occur against the backdrop of cognitive and psychosocial development, with treatment decisions having lifelong implications.
This article will provide an overview of treatment modalities, with emphasis on the future direction of interventions targeting aggression in children with autism.
Treating bipolar disorder in young patients can often result in aggravation, irritability or even reactivation depending on the type of medication used. What are typical examples of medication-induced rebound and what are the implications of these types of responses in children?
A discussion about new depression treatments with the chairperson of Stanford University’s department of psychiatry, Alan Schatzberg, M.D.
Individuals with schizophrenia are at greater risk for weight gain than the general population. From recent research, it appears that some of the second-generation antipsychotics may be more likely to cause weight gain than others. Recommendations for treatment strategies are provided.
Posttraumatic stress disorder is one of the most devastating psychiatric disorders. Research has shown that a combination of multiple genes can lead to conditions for PTSD. Environmental factors, as well as comorbidities, must also be considered when looking for genetic conditions of PTSD.
Although lithium is still a first-line treatment for bipolar disorder, many psychiatrists are reluctant to use it due to blood monitoring requirements. The FDA has approved an in-office blood test that allows lithium blood levels to be obtained in minutes. The test is similar to glucose monitoring devices used for diabetes, and experts on BD are hoping it will increase the use of lithium, which has also been shown to lower the suicide rate among patients with this disorder.

While the utilization of clinical genotyping to determine drug response and dosage has been anticipated for many years, the actual utilization of screening for atypical drug metabolizers has only recently become a reality. What is the promise of this technology, as well as the limitations?
New research into the genetic basis and possible genetic markers for attention-deficit/hyperactivity disorder may open the door for new treatments. There is a clear concordance between twins who have ADHD, as well as siblings. What can genetic mapping tell us about treating ADHD?

"The use of restraints . . . may have catastrophic impact on outpatient treatment compliance, leading to a vicious cycle of noncompliance followed by admission to a PES, with the possibility of repeated use of restraints."

An estimated 1,368,000 new cases of invasive cancer were diagnosed and 563,700 cancer-related deaths occurred in the United States in 2004
The infamous trial of People v Schmidt, presided over by Justice Benjamin Cardozo, provides a cautionary tale for forensic psychiatrists. In his commentary on a biography of the celebrated judge, Stone assesses the quest to clarify the meaning and scope of the insanity defense.
Suicidal behavior is a complex and multi-factorial phenomenon for which epidemiological genetics suggests a genetic basis that may be specific and independent from those implicated in the vulnerability to the psychiatric disorders associated with SB. Recently, new molecular biology tools have been designed to identify predisposition factors to complex disorders. One of the main goals of current studies is to specify the suicidal phenotype, as well as the intermediate phenotypes associated with these genes.
