Major Depressive Disorder

Treating bipolar disorder in young patients can often result in aggravation, irritability or even reactivation depending on the type of medication used. What are typical examples of medication-induced rebound and what are the implications of these types of responses in children?

A discussion about new depression treatments with the chairperson of Stanford University’s department of psychiatry, Alan Schatzberg, M.D.

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.

Posttraumatic stress disorder is one of the most devastating psychiatric disorders. Research has shown that a combination of multiple genes can lead to conditions for PTSD. Environmental factors, as well as comorbidities, must also be considered when looking for genetic conditions of PTSD.

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.

"Chemobrain," a term coined by patients in breast cancer support groups to describe cognitive impairment associated with chemotherapy, is becoming a subject of research.

Sensitivity and specificity of a new bipolar spectrum diagnostic scale.

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

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?

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.

With one in six Iraqi War veterans exhibiting mental health problems, psychiatrists are faced with the challenge of reducing or averting the psychological wounds of war and preventing long-term, service-connected disabilities. At the 13th Annual Medicine Meets Virtual Reality Conference, new therapies using virtual reality were put to the test.

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.

Traumatic events affect individuals as well as entire communities. In this Special Report on trauma and violence, a number of often forgotten traumatic experiences are described. The individuals exposed to these events are at increased risk of several psychiatric disorders, as well as behavioral changes such as increased alcohol use or cigarette smoking.

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

Is the HAM-D still viable? What are its flaws and is it possible to compensate for them?

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.

Prostate cancer, the second leading cause of cancer death in men, is the most common cancer in males in the United States. Out of an estimated 230,000 new cases in 2004, more than 70% will occur in men over age 65. Close liaison between urologists, prostate oncologists, radiation oncologists and psychiatrists allows for improved information transfer and proper referrals, as well as improved identification of the symptoms as being either physical, psychological or both.

Multiple studies show that diabetes approximately doubles the risk of comorbid depression. Furthermore, major depressive disorder is a risk factor for the subsequent development of type 2 diabetes mellitus. Treatments for depression in the setting of diabetes must be evaluated for their effects on blood glucose levels, propensity for weight gain, possible concomitant use for diabetic neuropathy and potential drug interactions.

Comorbid substance use disorders may complicate treatment for both the hepatologist and psychiatrist. Comprehensive assessment of psychiatric illness and psychopharmacological management may be critical.

Attempts have been made to integrate psychiatry and medicine as far back as Benjamin Rush, a physician and signer of the Declaration of Independence. Recent advances in research, clinical practice and organizational makeup, however, now make integration seem more plausible than ever. Find out what's happening to bring these two fields closer together.

Three recently published studies uncovered some answers to the genetic underpinnings of depression. Familial vulnerability was shown to increase with each generation affected by depression. Two genetic variants pointed in opposite directions: one showed an increase risk of depression and the other predicted responsiveness to antidepressants.

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.

It’s a classic risk/benefit dilemma: Does preventing suicidality-assuming suicidality can predict suicide-justify scaring some doctors away from prescribing antidepressants for young patients?

The prevalence of major depression following stroke ranges from 10% to 40%. Other psychiatric disorders, including anxiety disorders, apathy and cognitive impairment are also common. Psychiatrists need to be on the lookout for symptoms not just immediately poststroke, but up to six months after the event.

In the second part of this series, read about the special issues psychiatrists face when treating women, children and adolescents, and elderly people with bipolar disorder and dementia. What are the recommendations for care and monitoring strategies to maintain patients on effective, long-term treatment regimens?

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.

Although a lot remains to be learned, much is already known about the early childhood characteristics that predispose children to antisocial behavior and violence in adolescence and early adulthood, an expert in psychopathology said recently at a National Institutes of Health conference.

It has been well established that there is a high incidence of depression in conjunction with Alzheimer's disease and other forms of dementia. What are the best assessment and diagnostic methods, and which treatments will produce the best results?

The relationship between depression and epilepsy is bidirectional as not only are patients with epilepsy at higher risk of developing depression but patients with depression have a three- to sevenfold higher risk of developing epilepsy. Several studies have found that the presence of depression in patients with intractable epilepsy was a stronger predictor of poor quality of life than the frequency and severity of seizures. The principles of managing depression in epilepsy are reviewed in this article.
