Schizophrenia/Psychosis

New tests approved by the FDA can allow clinicians to genetically test for patients who may be low- or high-responders to certain drugs. How effective are these tests and what might the ethical implications be?

Ever since antiquity, thinkers have associated creativity with psychopathology--the classic idea of the "mad genius."

During a trip to Beijing on behalf of the World Psychiatric Association, Dr. Stone witnessed up close how the psychiatry is practiced in today's China. What he found may surprise you--it certainly surprised him.

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.

"Pseudodementia" needs a third look. Always a "soft" diagnosis, it has never had objective, explicit diagnostic criteria or a spot in an official nomenclature.

More than 100 neurologic diseases, injuries, and intoxications are known to prominently or exclusively involve the white matter of the brain.

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.

The post-stroke patient is at significant risk for various psychiatric syndromes. The most commonly reported of these in the literature are post-stroke depression (PSD) and post-stroke dementia (PSDem), which may present simultaneously with overlapping mood and cognitive symptoms. In this article, we offer a review of current literature on post-stroke psychiatric syndromes and an integrated clinical approach to screening, diagnosis, and pharmacologic intervention.

Clinical Trial Enrollments

Tricyclic antidepressants and antipsychotics are known to prolong cardiac repolarization and induce QTC interval prolongation, possibly putting patients with mental disorders at higher risk of cardiovascular diseases. The mechanism of gender difference in vulnerability for cardiovascular diseases is still unclear, but the role of hormones is one of possible explanatory factors.

What special issues do psychiatrists face when treating women, children and adolescents, and elderly people with schizophrenia? Are there recommendations for care and monitoring strategies to maintain patients on effective, long-term treatment regimens?

Are the metabolic side effects of the atypical antipsychotics fueling the next round of malpractice suits being filed against psychiatrists? Guidelines are being created, but how can clinicians protect themselves and their patients, while continuing to give their patients the best care available?

Migraine affects approximately 12% of the population, and a high percentage of these patients have comorbid psychiatric disorders. Knowing more about the interaction between headache and psychiatric factors can assist in evaluating and treating these patients.

Despite the fact that awareness of HIV and AIDS transmission is pervasive, risky sexual behavior has been increasing in many parts of the world in recent years, with a concomitant rise in new cases of HIV and other sexually transmitted diseases.

The diagnosis of bipolar disorder in children remains controversial. One of the more disturbing facets of its presentation in such young patients is the presence of hypersexual behavior. How can these behaviors be differentiated from the effects of abuse and other psychiatric disorders?

Given that a substantial minority of patients don't respond to monotherapy, clinicians may have to consider combined or augmentation therapy. According to the research, which drugs are most effective, and in which combinations?

A greater understanding of how the brain works, including the effect of environment on it development, has led to advances in diagnosing and treating psychopathology. The latest findings will be presented at an international meeting, along with a discussion of how much work is to be done and the great need for qualified child psychiatrists, especially in developing countries.

According to the World Health Organization, five of the 10 leading causes of disabilities worldwide are psychiatric conditions. More than 450 million people worldwide suffer from mental and brain disorders, and nearly 1 million people commit suicide each year. Because of this, many health care organizations and governments are forging partnerships to combat the daunting talk of providing quality health care around the globe.

Evidence-based treatment has not always been a common model in the field of psychiatry. Its popularity has grown over the last five years, though, as the body of scientific evidence into mental health has grown as well.

The number of magnetic resonance spectroscopy studies that assess the levels of different neurochemicals in bipolar disorder has increased considerably in recent years. Abnormalities were reported mainly in the brain regions implicated in the pathophysiology of BD: the dorsolateral prefrontal cortex, cingulated gyrus, hippocampus and basal ganglia. Although these findings are not diagnostic, future research in this area may help to elucidate the pathophysiology of BD and monitor treatment effects.

Although eating disorders have been considered to be largely sociocultural in origin, findings from family, twin and molecular genetic studies conducted during the last decade are refuting that perspective. Recent studies have had significant success in isolating specific chromosome regions that may harbor susceptibility loci for anorexia and bulimia nervosa and are helping to shed light on the degree of heritability of eating disorders.

Transcranial magnetic stimulation has been applied in a growing number of psychiatric disorders as a putative treatment. As a focal intervention that may exert lasting effects, TMS offers the hope of targeting underlying circuitry and ameliorating the effects of psychiatric disorders. The ultimate success of such an approach depends upon our knowledge of the neural circuitry involved, on how TMS exerts its effects and on how to control its application to achieve the desired effects. Current challenges in the field include determining how to enhance the efficacy of TMS in these disorders and how to identify patients for whom TMS may be efficacious.

Assessing and treating patients with suicidal behavior is not an easy task. Acts of suicide cannot be predicted; the best a psychiatrist can hope for is the ability to identify a patient's risk factors and reduce them. With the publication of a new practice guideline, it is hoped that psychiatrists will be better equipped to deal with this particularly vexing challenge.

Borderline personality disorder is a complex, disabling disorder. The chairperson for the American Psychiatric Association workgroup for the evidence-based practice guideline on its treatment gives an overview of this disorder's etiologies, neurobiology, longitudinal course and recommended treatments. Future directions for both treatments and research are also discussed.
