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.

Many physicians who work in the emergency department (ED) consider the agitated patient the bane of their existence. These patients are frequently difficult to deal with, are uncooperative, and can bring an already busy ED to its knees. Although it is easy to understand why severely agitated patients are commonly placed in restraints or seclusion, it is essential that cooler minds prevail when an agitated patient presents to the ED. The patient should be treated with dignity, respect, and understanding. Because these patients often cannot express their feelings adequately, many who work in the ED do not realize that these patients do not like the feeling of being out of control.

The use of restraint and seclusion remains a controversial issue, and emergency care providers must remain absolutely current on it. We can come under criticism both for using too much coercion and for not using enough. Restraint and seclusion exist at an intersection of science, government policy, and public perception. These seemingly straightforward forms of medical coercion are still, in actuality, far from straightforward.

Impulsive behaviors play an important role in both bipolar and substance abuse disorders. However, results of studies investigating this link are often ambiguous, in part, due to the multidimensional nature of the impulsivity construct and the fact that many studies use a single measurement technique. We describe a model of impulsivity characterized by three components: response initiation, response inhibition and consequence sensitivity. How these components differ from one another in terms of their use, behavioral theory and biological function is discussed, along with measurement techniques.

Marijuana is the number one illegal drug of abuse in the United States; in second place is the nonmedical use of prescription medications such as pain relievers, tranquilizers, stimulants and sedatives. The National Institute on Drug Abuse is intensifying its research in understanding mechanisms that underlie the reinforcing, addictive and toxic properties of prescription medications, and developing medications with less abuse potential.

In a variety of creative fields, psychiatrists have been portrayed in many ways. This Special Report is psychiatry's turn to address creativity with offerings as diverse as the creative arts themselves. From Shakespeare to rock 'n' roll, there's something for everyone.

Sometimes it pays to look at something in a different way. Growing up in rural Georgia, I hated kudzu. My disdain began as soon as I was old enough to mow the lawn. The creeping vines relentlessly tried to expand from their ceded territory and take over the civilized section of my parents' property.

Diagnosis of the two main major eating disorders, anorexia nervosa and bulimia nervosa, can be difficult because of denial of symptomatology by the patients and problems with some of the diagnostic criteria. Although CBT has been the most effective, there are no treatments available that can guarantee a cure for either disorder. Medication is only a helpful adjunct to the treatment of anorexia, while many controlled studies that show antidepressant medications are effective in reducing binge/purge behavior in bulimia.

Psychiatric evaluation of juveniles who commit murder is perhaps one of the most difficult tasks in forensic psychiatry. A study has shown that these inmates are more likely to have been abused, be addicted to drugs or alcohol, or have a serious psychiatric disorder. Additionally, they are more likely to engage in risky behavior without thinking about the consequences.

Alzheimer disease (AD) affects between 6% and 8% of Americans older than 65 years. As the population of older adults increases, the number of persons with AD is expected to rise from 4.5 million in 2000 to 13.2 million by 2050.1 This disease is important not only because of the number of patients affected but also because it leads to significant physical and emotional burdens on families and caregivers.

Sildenafil (Viagra, Pfizer) may help patients recover from stroke by aiding regeneration of brain cells. After successfully proving that the drug stimulates cortical neurogenesis in experimental models of stroke, researchers from the Henry Ford Hospital in Detroit have now embarked on a clinical trial of sildenafil and plan to recruit 84 patients who have suffered a moderate stroke within 72 hours of entering the study.

Osteoporosis is a disorder characterized by low bone mass and microarchitectural deterioration with resulting compromised bone strength and increased risk of fracture.1 The World Health Organization defines osteoporosis based on T-scores, which reflect bone mineral density (BMD) relative to mean BMD for healthy 25-year-old same-sex populations. A T-score between 0 and 21 is considered normal density, a score between 21 and 22.5 indicates osteopenia, and a score of less than 22.5 signifies osteoporosis.2 Severe osteoporosis is defined as a T-score of less than 22.5 combined with a fragility fracture.2

Little attention has been paid to the prevalence of sexual assault and its sequelae among military men. The past-year prevalence of sexual assault among enlisted men ranges from 0.4% to 3.7%, a figure equal to or exceeding the lifetime prevalence among civilian men in some studies. Increased awareness and understanding of male sexual assault as well as routine screening of all patients, regardless of gender, for exposure to sexual victimization will enhance their recovery.

Road rage is well known in popular culture and to many people it is a common and dangerous experience. Alcohol problems, illicit drug use and general psychiatric distress are associated with road rage perpetration. Road rage incidents may also result in psychiatric distress. Although treatment for road rage has received little research attention, encouraging results have been reported from specialized programs.

Traumatic events affect individuals as well as entire communities. In this Special Report on trauma and violence, a number of often forgotten traumatic experiences are described. The individuals exposed to these events are at increased risk of several psychiatric disorders, as well as behavioral changes such as increased alcohol use or cigarette smoking.
