Schizophrenia/Psychosis

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?

Long recognized by peers and students alike for his teaching excellence, Henry Nasrallah, MD, was named Teacher of the Year at the 18th annual U.S. Psychiatric & Mental Health Congress. In an interview with PT, Nasrallah talks about his passion for the field of psychiatry and his clinical research in schizophrenia.

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.

Smokers with co-morbid psychiatric and substance use disorders smoke at a much higher rate and seem to have more difficulty quitting than those in the general population. Tobacco treatment that is integrated into mental health settings may lead to greater success than non-integrated treatment. As a result, mental health care providers can play a critical role by careful assessments of smoking, employment of motivational techniques and increasing access to pharmacological and behavioral treatments.

Treatment compliance is a crucial determinant of the outcome of any disease. Poor treatment compliance can worsen the prognosis and significantly increase health care costs. Effective methods to improve treatment compliance for individuals with comorbid mental illness and SUDs will translate in better outcome for the patients and significant health care cost savings.

Are all treatments for schizophrenia created equal? With Phase I of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study completed, five pharmacological options have been compared in an attempt to answer this question. Results from this portion of the trial have been released and are discussed.

Three psychiatrists give their perspective on helping victims of one of the nation's worst natural disasters.

A number of highly publicized cases in the lay press have underscored the significance of, and dangers associated with, perinatal psychiatric illness. Unfortunately, the field of psychiatry has failed to use these tragic cases to disseminate accurate information and educate the public about the high frequency of perinatal depression and anxiety, as well as the relative rarity of postpartum psychosis and infanticide. Moreover, psychiatrists continue to have difficulty in educating their medical colleagues about the need to screen for these illnesses, so most obstetricians and pediatricians still do not screen for perinatal depression and anxiety, much less manage it effectively. Decisions about appropriate treatment are further complicated by a lack of empiric outcome data.

Over the past decade, there has been increasing attention to the identification and management of mood and anxiety disorders related to childbearing. Emergen- cy physicians, including psychiatrists, primary care providers, obstetricians, gynecologists, and pediatricians, encounter women who are struggling with mental health issues in the context of reproductive events, such as pregnancy, pregnancy loss, and the postpartum adjustment period. In some cases, the reproductive event may precipitate a mental health crisis. In others, it may exacerbate an underlying mental health condition that, in turn, may need to be managed differently because of issues related to pregnancy or breast-feeding.

An expert in the topic explores the historical background that led to problems with boundary violations in psychotherapeutic practice and describes community standards for professional boundaries when practicing psychotherapy. The difference between boundary crossings and boundary violations is clarified and discussed, as are the psychological types most likely to violate those boundaries. Possibilities for rehabilitation and the format for rehabilitation are also provided.

Selective serotonin reuptake inhibitors have been shown effective in the treatment of depression with psychosis. This efficacy appears to correlate with the SSRIs’ level of affinity at the sigma-1 receptors in the brain. What role does the sigma-1 receptor play in psychotic depression? Based on this role, are there implications for other treatments?

New Clinical Drug Evaluation Unit presented new clinical data at their 45th annual meeting in Boca Raton, Fla. In the first of two articles, suicide studies, the effectiveness of antidepressants and the efficacy of drug combination therapy are explored.

The incidence of polypharmacy is on the rise, and with the increase comes a greater risk of drug-drug reactions. One survey estimated that patients seeing a psychiatrist may be six times more likely to receive multiple psychotropic medicines compared to patients seen by a primary care physician. This article provides an overview of the extent of polypharmacy, the factors driving the phenomenon and issues clinicians should consider when treating patients who are already taking medicines for other illnesses.

Comorbidity of Dysthymic Disorders in Children and Adolescents by Atilla Turgay, M.D. Many patients with dysthymic disorders also have associated comorbid disorders. A detailed history will provide insight into the comorbidity profile, cross-sectionally and developmentally. Dysthymic disorder should be addressed clinically, as it may cause long-term chronic unhappiness and poor quality of life for the patient.

Through the Times With Max Fink, M.D. by Arline Kaplan Long viewed as a pre-eminent researcher and advocate for electroconvulsive therapy, Max Fink, M.D., reflects on more than five decades of groundbreaking research.

Updates Show Progress in TMS for Depression and Schizophrenia by Arline Kaplan In research presented at the 2005 APA annual meeting, transcranial magnetic stimulation is showing efficacy in treating depression and schizophrenia in the research setting. The question of how to translate those findings to a real-world setting still remains.

The Emerging Role of GABAergic Mechanisms in Mood Disorders by Po W. Wang, M.D., and Terence A. Ketter, M.D. Gamma-aminobutyric acid is a major inhibitory neurotransmitter widely distributed in the mammalian central nervous system. Animal models of depression have pointed toward the importance of the GABA system in the pathophysiology of mood disorders. Thus, elucidating the GABAergic effects of benzodiazepines, mood stabilizers, antidepressants, and new anticonvulsants and antipsychotics may expand our understanding of mood disorder pathophysiology and potentially generate new targets for treatment.

Individuals with schizophrenia are at greater risk for weight gain than the general population. From recent research, it appears that some of the second-generation antipsychotics may be more likely to cause weight gain than others. Recommendations for treatment strategies are provided.

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.

Recent research has shown environmental factors may increase the risk of schizophrenia in persons who may already have a genetic predisposition toward the illness.
