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?

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.
Research at the Crossroads of Genetics and Psychiatry
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.
Restraints and seclusion have been used for many years in emergency departments (EDs) and psychiatric emergency services (PESs), but anecdotal case reports and newspaper investigations as well as clinical advances have led to restrictions in their use.
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.
In an attempt to reframe the either-or debate over the impact of genetics versus environment on emotional makeup, a panel convened at the American Psychoanalytic Association’s Winter 2005 Meeting in New York City. This article highlights studies presented at the meeting.
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.
Proposed changes in the conceptualization of compulsivity and impulsivity in the DSM-V will have important implications in the way clinicians recognize and treat these disabling conditions.
One of this year’s recipients of the National Medal of Science sits down to talk with Psychiatric Times about his research, accomplishments and music.
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.
Comparative data are emerging on the metabolic effects of the second-generation antipsychotics on adolescents and children. Data presented at national meetings is discussed. When using these medications, the risks and benefits need to be carefully weighed until more definitive information is available.
On physical examination, the patient appeared well, except for the obvious diffuse rash. Erythematous macules, papules, and patches covered his extremities, face, trunk, palms, and soles. His conjunctivae, mucous membranes, and joints were normal, as were the results of cardiac, pulmonary, abdominal, and neurologic examinations. Several anterior and posterior cervical lymph nodes (0.5 to 1 cm) were present bilaterally.
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.
Psychiatrists have often turned to literature for theory building, clinical understanding and teaching. Hamlet is a common example, beginning with Freud. Most psychiatrists, like Freud, look at content (character and motivation) when using literature. However, the process (interaction between characters) can also teach us much about the psychiatrist-patient encounter.
Plenty of data show that a greater share of physicians practice in urban than in rural areas. The Council of Graduate Medical Education called it geographic maldistribution, "one of the most enduring features on the American health landscape," and said that it is likely to continue until universal health care is enacted.
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.
At first glance, PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection) has little in common with the cuddly bear that roams the bamboo forests of southwest China. But, in fact, they share 2 important features: both are rare and both are threatened with extinction.
Patients with chronic pain have always posed big challenges for neurologists, both in diagnosis and in treatment strategies. Why and how neurologists treat pain, however, is dynamically changing.
Can a common cough medicine contribute to effective treatment of symptoms in persons with neurologic disorders? The evidence is mounting in its favor. At the recent American Academy of Neurology annual meeting, research results were presented from a phase 3, double-blind, placebo-controlled, multicenter study into the safety and efficacy of a dextromethorphan/quinidine capsule in
Ever since antiquity, thinkers have associated creativity with psychopathology--the classic idea of the "mad genius."
When Gordon R. Kelley, MD, was called to the ICU in Kansas City, Mo, to evaluate a deteriorating patient who had apparently overdosed on methadone, he was puzzled. CT and MRI scans revealed an obstructive hydrocephalus associated with abnormal signals throughout the cerebellum, basal ganglia, and hippocampi. He knew that these findings were not consistent with a typical cerebrovascular injury, but he and other treating physicians were unsure of the cause of the findings. Reaching for his handheld computer, he entered several key words into his favorite program, NERVLINE: cerebellum . . . heroin . . . leukoencephalopathy
