Inflammation, Psychosis, and the Brain
July 11th 2009When the solution to a clinical or scientific puzzle eludes us for more than a century, as with schizophrenia, we need new methods to examine the pathology. If we want to make an impact on the disease we must shift research paradigms and focus on the early detection, early intervention, and new avenues of treatment that address different symptoms of schizophrenia.
Delirium With Catatonic Features: A New Subtype?
July 10th 2009Delirium has been recognized and described since antiquity. It is a brain disturbance manifested by a syndrome of diverse neuropsychiatric symptoms. Various terms have been used for delirium, such as acute brain disorder, metabolic encephalopathy, organic brain syndrome, and ICU psychosis.
PTSD Is a Valid Diagnosis: Who Benefits From Challenging Its Existence?
July 10th 2009PTSD filled a nosological gap by providing a way to characterize the long-lasting effects of trauma exposure.1 This led to a plethora of previously lacking scientific observations. Now the existence of PTSD is being called into question because some of the original assumptions that helped make the case for it have proved to be incorrect.2-4 However, it is possible to update some of the flawed assumptions of PTSD without rescinding the diagnosis. There is no reason to throw the baby out with the bathwater.
PTSD Has Unreliable Diagnostic Criteria
July 10th 2009Currently the Veterans Administration (VA) is the world’s largest recipient of per patient funding for PTSD. The VA treats 200,000 veterans with this diagnosis annually at a cost of $4 billion. But research calls into question the very existence of the “PTSD” syndrome, and its diagnostic formulation remains invalid. We do not minimize the suffering of those who experience trauma or the need for comfort and restitution. We seek only to reexamine research evidence, to clarify the impact of culture on diagnosis, to reevaluate the consequences of trauma, and to ensure optimal allocation of resources.
Complementary, Alternative, and Integrative Rx: Safety Issues
July 7th 2009Findings of a recent large population survey suggest that 1 in 3 adults in this country (approximately 72 million people) uses 1 or more complementary and alternative medicine (CAM) modalities during any given year.1 Many CAMs are widely regarded as safe on the basis of their established uses in traditional systems of medicine over centuries or longer and their current widespread use in the United States and other Western countries. Unfortunately, there is limited reliable information on potential risks associated with the majority of these approaches.
Inside the DSM-V Process: Issues, Debates, and Reflections
July 6th 2009Being a member of 1 of the 13 working groups of the DSM-V Task Force is, indeed, a unique experience. Having a large number of respected colleagues working diligently on areas that they have mastered with indisputable authority over the years is an intellectually fascinating experience.
Death of Psychiatrist and Other Soldiers Triggers Inquiry Into Military’s Mental Health Care
July 6th 2009Alarmed by the rising suicide rate among soldiers returning from Iraq and Afghanistan and “wanting to help,” Matthew “Matt” Houseal, MD, a psychiatrist with the Texas Panhandle Mental Health Mental Retardation Center (TPMHMR), reenlisted as an Army Reservist and volunteered to serve in Iraq.
A Visit to Auschwitz: Reflections on Biology and the Psychiatric Sequelae of Political Violence
July 3rd 2009If I closed my eyes, it would have been easy to imagine that I was visiting a peaceful city park. The sounds of birdsong and children’s laughter rang in the air, and the odor of freshly cut grass filled my nostrils. But the sweet smells and soothing sounds belied the horror of the place where I actually stood-inside the wrought iron gates of Auschwitz-Birkenau, the Holocaust’s most infamous concentration camp. Today the camp is a museum, and there is an eerie dissonance between the tranquility of its sprawling grounds and the mass murders that were carried out here almost 70 years ago. Like many visitors to Auschwitz, I experienced powerful emotions-a mixture of revulsion, anger, and a deep empathy for the millions of souls who suffered and perished there. I also felt a discomfiting sense of doubt about the goodness of humanity, including my own.
Functional Magnetic Resonance Imaging: Round 2
July 1st 2009This is the second installment in a 3-part series that discusses some of the mechanisms behind functional magnetic resonance imaging (fMRI) technology. As you may recall, the genesis for this series was reactive…I got mad while sitting on an airplane reading a magazine article about how fMRIs can predict everything from product preferences to political inclination. The article hinted at something I have been noticing with increasing alarm-the confusion about what fMRI can and cannot reveal about information processing in the brain. I decided to write this series hoping that knowledge of the basic science behind fMRI technology could contribute to making more nuanced conclusions about the data it reveals.
Development of a Transdiagnostic Unified Psychosocial Treatment for Emotional Disorders
Research emerging from the field of emotion science suggests that individuals who have anxiety and mood disorders tend to experience negative affect more frequently and more intensely than do healthy individuals, and they tend to view these experiences as more aversive, representing a common diathesis across anxiety and mood disorders.1-5 Deficits in the ability to regulate emotional experiences, resulting from unsuccessful efforts to avoid or dampen the intensity of uncomfortable emotions, have also been found across the emotional disorders and are a key target for therapeutic change.
