The recent evolution of neuropsychiatry/behavioral neurology as a subspecialty represents a paradigmatic shift regarding the responsibility of psychiatrists in diagnosing and managing behavioral disorders with concomitant and demonstrable brain pathology such as dementia or head injury. This authors define the clinical usefulness of electroencephalography in evaluating neuropsychiatric disorders.

The FDA advisories warning of increased suicide risk among children and adolescents beginning antidepressant therapy have alarmed the health care community--but it may actually be a disservice to withhold these medications from those who need them.

As many as 90% of Americans are exposed to at least one traumatic event in the course of their lives. Many more are exposed to more than one traumatic event. Short- and long-term sequelae of traumatic exposure vary greatly and range from complete recovery, to severe and debilitating PTSD.

About 25% of patients seen in epilepsy clinics and monitoring units who do not respond to antiepileptic drugs (AEDs) have received a misdiagnosis.1-3 The eventual diagnosis for most of these patients will be psychogenic nonepileptic seizure (PNES)1,4-a somatoform conversion disorder. It is treatable, but diagnosis, delivery of the diagnosis, and management present significant challenges. A major barrier to care has been the stigma associated with the label "psychogenic."

Dementia is characterized as a progressive and chronic decline in cognitive function, not limited to memory impairment, which significantly interferes with baseline daily functioning and frequently involves behavioral disturbances. It is known that behavioral problems in dementia negatively affect patients and caregivers. These disturbances lead to institutionalization, increased costs and caregiver burden, and a poorer prognosis.

Anxiety disorders are the most common mental conditions in the general population, including in children and adolescents. Young people can present with a pattern of anxiety symptoms somewhat different from that typically seen in adults. One of the most common aspects of this difference is that children (especially younger ones) may not report overt worries or fears, but instead manifest pronounced physical symptoms.

Well into the 1970s, we psychiatrists believed that depression came from anger turned inward-and we acted on this notion. Psychiatrists spent countless hours trying to get depressed patients to talk about their anger. Enterprising psychologists and psychiatrists devised schemes to make such patients angry.

Schizophrenia poses a challenge for diagnosis and treatment at least in part because it remains a syndromal diagnosis without clearly understood neuropathological bases or treatments with clearly understood mechanisms of action. Neuroimaging research promises to advance understanding of the unique pathological processes that contribute to this syndrome, and to foster both better appreciation of how current treatments work, and how future treatments should be developed.

Although several clinical studies suggest that cognitive impairments in schizophrenia are associated with reduced stimulation of dopamine receptors in the prefrontal cortex, mounting evidence suggests that other monoaminergic neurotransmitter systems may also be involved. We provide an overview of neurotransmitters that hold promise as therapeutic interventions for the cognitive deficit in schizophrenia.

It was not too long ago that the management of schizophrenia focused primarily on symptom relief in inpatient and outpatient settings. Over the past two decades, there has been a paradigm shift in our approach in the overall management of schizophrenia, toward preventive and early interventions. What are some of these management techniques, and how well do they work?

Alcohol and substance use disorders take a tremendous toll on society as a whole and also require significant emergency department (ED) resources. Alcohol use and abuse in the United States accounts for over 100,000 deaths each year1 and costs more than $185 billion annually.2 A study of the effects of alcohol-related disease and injuries found that the number of patients who presented with these conditions increased by 18% from 1992 to 2000.3

The use of benzodiazepines in psychiatry and general medicine is fraught with controversy because of the potential for abuse and dependence. In daily practice, clinicians vary widely in their comfort level with prescribing this class of medications, whether for short-term relief of panic or for long-term prophylaxis of generalized anxiety. The use of benzodiazepines in acutely traumatized persons is particularly controversial.

Assessment and management of dual diagnosis--that is, the comorbidity of substance use disorder in persons with mental illness--is a major challenge for clinicians, especially in the emergency department (ED). It is widely accepted, but perhaps less well appreciated in the clinical realm, that substance abuse comorbidity is more the rule than the exception in persons with serious mental illness.

Proper evaluation of patients for alcohol and substance use disorders is usually time-consuming. When done in a busy emergency department (ED), assessment is often rushed, increasing the likelihood of misdiagnosis and, therefore, mismanagement. Because the evaluation is a patient's first step to effective therapy, it should be conducted as efficiently and effectively as possible.

If done properly, the assessment of alcohol and substance use disorders in the emergency department (ED) or psychiatric emergency service can be the first step toward recovery. A proper assessment, however, can be extremely taxing for both the clinician and the patient. This article offers a paradigm for performing a rapid and comprehensive evaluation in the ED of medically stable adults with alcohol and substance use disorders.

With its focus on both behavior modification and mindfulness training, dialectical behavior therapy has proven quite effective in treating patients with borderline personality disorder. This article provides a primer on a modified version of this outpatient treatment for borderline patients with substance use disorders, a comorbid condition that may affect as many as two-thirds of patients with BPD.

The U.S. Departments of Defense and Veterans Affairs have developed protocols for assessing soldiers returning from combat operations in Iraq and Afghanistan. With data showing that many veterans do not show psychiatric symptoms until three to six months after returning home, a new post-deployment assessment was created and is ready to roll out. In the meantime, a jump in PTSD cases led to an internal review at the VA.
