Addiction & Substance Use

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

Are juveniles mature enough to receive the death penalty? No, according to a ruling by the U.S. Supreme Court. Medical, psychiatric, psychological and brain-imaging data all supported the decision to ban execution of juvenile death-row inmates.

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.

The FDA has issued a "black box" warning about the use of all antidepressants in the pediatric population due to a 1.8-fold increase in suicidality on drug compared to placebo. Yet these medications can be an effective tool in treating depression. How should parents and patients be educated, considering this information?

Autism is a highly prevalent, highly heterogeneous disorder of unknown etiology. Studies to clearly establish the efficacy of various classes of psychoactive drugs are scarce. Nonetheless, available findings do support the efficacy of atypical antipsychotics and antidepressants in treating the core symptoms of repetitive behavior.

Heavy smoking and caffeine intake are highly prevalent in patients with psychiatric disorders, both of which significantly impact the metabolism of a number of psychotropic medications. Hence, these factors should be routinely considered in making prescribing decisions.

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.

The dozens of journalists killed while covering the current war in Iraq gives currency to the dangers encountered by those who bring us the news from the world's conflict zones. Despite the risks inherent in their profession, it is only recently that the psychological health of war reporters has been captured in a systematic and empirical manner.

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.

Youth gangs are a recognized risk factor for adolescent violence and delinquency. This article reviews recent research on these topics, including the prevalence, characteristics and influence of youth gangs, and discusses the implications of those findings for clinical practice.

Dr. Gabbard discusses using psychotherapy and psychiatry combined, how media portray psychiatrists and why Tony Soprano does the things he does.

Mental illness occurs more frequently among people infected with HIV. In addition, individuals with mental illnesses are at greater risk for contracting HIV. Therefore, psychiatry has a great deal to offer in the management of patients with HIV--whether through proper patient education or safe and effective psychopharmacology.
