Major Depression on the Rise in the United States
March 1st 2007Treatment interventions via telephone, Internet, and through other telemedical services are gaining popularity, especially in rural areas where licensed clinicians might not be available. Dr Per Carlbring and colleagues recently evaluated a 10-week, Internet-based, self-help program with weekly telephone calls for patients who had panic disorder with or without agoraphobia. The results were published in the December 2006 issue of the American Journal of Psychiatry.

Stroke Complications: Hiding in Plain Sight?
March 1st 2007Despite the enormous progress made in stroke diagnosis and treatment in recent years, patients continue to experience stroke-related deficits that clinicians-even those working on stroke rehabilitation units-do not always recognize or record. In a recent study of 53 patients who underwent screening tests within 10 days of admission to a stroke unit, every impaired patient had at least 1 undocumented cognitive or sensory deficit. The authors suggested that without formal testing with standardized assessments, much stroke-related impairment goes unrecognized and perhaps untreated.

The Neurobiology of Cocaine Dependence and Its Clinical Implications
March 1st 2007Cocaine dependence is a devastating disorder that is associated with a host of medical and psychosocial risks. This complex disorder is made up of distinct clinical components that are interwoven into a cycle of addiction (Figure 1). Cocaine activates ancient pleasure centers that dominate our thoughts, behaviors, and priorities, producing a pleasure-reinforced compulsion to use the drug. Repeated use dysregulates brain pleasure centers and paves the way to addiction through craving and impaired hedonic function.1 Euphoria and craving drive the cycle of addiction through positive and negative reinforcement, respectively, and they provide targets for pharmacological interventions.

Drug Therapies for the Neurobehavioral Sequelae of Traumatic Brain Injury
Traumatic brain injury (TBI) is one of the most common causes of morbidity and mortality, especially in young adults. Recognition and early accurate diagnosis of neurobehavioral TBI sequelae are important in reducing the severity of postinjury symptoms. Sequelae of TBI include cognitive impairments, personality changes, aggression, impulsivity, apathy, anxiety, depression, mania, and psychosis.

Treatment of Somatic Symptoms in Generalized Anxiety Disorder
March 1st 2007Generalized anxiety disorder (GAD) is characterized by excessive or unrealistic anxiety and worries about life circumstances. In the general population, the prevalence of GAD is 2% to 5%. It is the most frequent anxiety disorder seen in primary care, where 22% of patients complain of anxiety problems.1 DSM-IV lists 6 somatic symptoms associated with GAD: restlessness, increased fatigability, difficulty in concentrating, irritability, muscle tension, and sleep disturbance. These symptoms may present with hyperarousal, hypervigilance, and heightened muscle tension; autonomic symptoms are milder than in other anxiety disorders and can be absent.

Delirium: Emergency Evaluation and Treatment
March 1st 2007Delirium is a disorder that lies at the interface of psychiatry and medicine. It is an acute organic syndrome caused by an underlying medical condition and is defined clinically by disturbances in cognitive function, attention, and level of consciousness.1 Delirium is considered a syndrome because of the constellation of signs and symptoms associated with the disorder, coupled with a wide variety of potential etiologies.

What is the best approach for management of depression in a pregnant woman after a suicide attempt?
March 1st 2007Although suicidal ideation occurs in roughly 5% to 14% of pregnancies,1 suicide attempts are relatively rare (0.04%) and are associated with substance abuse and poor pregnancy outcome.2 After a suicide attempt, the clinician must first consider the possibility of recurrence of self-destructive behavior by assessing the woman's motivation, her attitude toward the pregnancy, and the severity of her depressive symptoms.

The Role of Population and ED Trends in Delirium Management
March 1st 2007In this issue, Drs Heinrich and Sponagle present a thorough overview of the challenges of detecting and treating delirium in the emergency care setting. They also address the high risks involved when the diagnosis is missed. The difficulties of identifying and appropriately managing delirium are not new. However, the importance of doing so is taking on a greater significance because of certain current and forecasted realities that will affect the nation's emergency departments (EDs).

Clinical Assessment and Management of Pathological Gambling
March 1st 2007Pathological gambling (PG) is characterized by persistent and recurrent maladaptive patterns of gambling behavior (eg, a preoccupation with gambling, the inability to control gambling behavior, lying to loved ones, illegal acts, and impaired social and occupational functioning).1 With past-year prevalence rates similar to those of schizophrenia and bipolar disorder,2 it is apparent that PG has become a significant public health issue. The aim of this article, therefore, is to introduce clinicians to the assessment and treatment of PG with the hope that early interventions will reduce the considerable personal and social costs associated with the disorder.

Finessing the Fine Line Between Pain Management and Opioid Addiction
February 1st 2007Up to 30% of patients for whom opioids are prescribed for chronic pain show an escalating pattern of opioid abuse characterized by taking more opioids than prescribed, seeking early refills, and finding additional sources of opioids. Although many of these drug-seeking patients are addicted to opioids, some are suffering not from addiction but from inadequate pain management, according to Martha Wunsch, MD, chair of Addiction Medicine and associate professor of pediatrics at Edward Via Virginia College of Osteopathic Medicine (VCOM) in Blacksburg.

Clinical Pearls on the Management of Parkinson Disease
February 1st 2007The ideal medication for Parkinson disease (PD) would reduce disability and halt or slow disease progression without intolerable adverse effects. Although such an agent is not yet available, current treatments offer significant symptom control for most patients. The decision about when to start therapy is highly individual; however, delaying treatment because of fear of adverse effects may not be in the patient's best interest.

Stroke Rare in Absence of Known Risks
January 6th 2007The reason a person has a stroke is no mystery. Results of a Danish study, reported at the 10th Congress of the European Federation of Neurological Societies in Glasgow, Scotland, held September 2 to 5, confirmed that risk factors could be identified in 98.5% of acute ischemic stroke patients.

Depression in Epilepsy: Chipping Away at Obstacles to Diagnosis and Care
January 1st 2007Clinical depression is an increasingly well-recognized sequela of epilepsy (see "Optimizing Treatment of Seizures by Addressing Psychiatric Comorbidities," Applied Neurology, August 2006, pages 41-42). Questions are therefore surfacing as to whether patients with epilepsy are being adequately identified and treated.

The Link Between Psychotic Disorders and Substance Use
January 1st 2007Psychotic disorders are a group of syndromes characterized by positive symptoms, including hallucinations, delusions, and thought disorder; and negative symptoms, including mood symptoms, social withdrawal, and reduced motivation. Cognitive deficits also appear with psychotic disorders. Psychotic disorders rank 22nd in the World Health Organization's list of worldwide causes of disability. This ranking is adjusted for the relatively low lifetime prevalence rate for psychosis; the perceived burden of the disease on those affected with psychotic disorders, as well as their relatives and caregivers, is much higher.

Psychiatric Disorders and Substance Abuse
January 1st 2007Substance use disorder (SUD) plays a prominent role in the epidemiology, cause, and course of mental illness.

Schizophrenia and Substance Abuse: Is There a Role for Atypical Antipsychotics?
January 1st 2007The prevalence of substance use disorders in patients with schizophrenia is greater than the rate observed in the general population, with a dramatic increase since the 1970s. Several theories exist to explain the high rate of comorbidity. The "self-medication" hypothesis suggests that persons may abuse substances to treat underlying psychotic symptoms or adverse effects of medications commonly used to treat schizophrenia.

School Shootings and What Psychiatrists Can Do to Prevent Them
January 1st 2007Psychiatrists certainly do not know all the answers when it comes to the recent spate of school shootings, but we do know some of the most pressing questions. For example, is there a difference in the psychological makeup of adult shooters versus student, or juvenile, shooters? To what degree does untreated psychosis or depression play a part in the shooter's seemingly inexplicable behavior? How important is bullying in motivating some students to seek revenge on their peers? What are the earliest warning signs of an impending attack by an assailant of any age?
