Neuropsychiatry

The FDA has cleared the first transcranial magnetic stimulation (TMS) device (Neuro-Star) for the treatment of major depressive disorder in adults who show no improvement after an adequate trial of a single antidepressant.

Our returning military veterans remind us dramatically of the importance to consider traumatic brain injury (TBI) as a potential comorbid illness in cases of posttraumatic stress disorder (PTSD). The common causes of comorbid TBI and PTSD are assault and battery to the head, head trauma (personal or work-related injuries), civilian or military explosions, inflicted head trauma in children, motor vehicle accidents, and suicide attempts by jumping. Prevalence figures for comorbid TBI and PTSD historically have been lacking

In the new century, the dementias will probably become 1 of the 2 or 3 dominant behavioral health problems in the United States. This article provides an overview of the major clinical features of these cognitive loss syndromes and emphasizes the perspective of the practicing psychiatrist.

Neuroimaging is often used in clinical psychiatry to rule out medical and neurological conditions that can mimic psychiatric disease rather than for the diagnosis of specific psychiatric disorders.

Unipolar major depressive disorder is a debilitating condition with a lifetime prevalence of 17%. Recent epidemiological evidence indicates that MDD is the fourth leading cause of disease burden and the leading cause of disability-adjusted life years.

Universal prevention has been a focus of psychiatric research for the past 4 decades. Using a public health approach, research has shown that mitigating major risk factors, such as poverty and early life stress, and promoting protective factors can improve behavioral outcomes.

Depression complicates medical illnesses and their management, and it increases health care use, disability, and mortality. This article focuses on the recent research data on diagnosis, etiopathogenesis, treatment, and prevention in unipolar, bipolar, psychotic, and subsyndromal depression.

Traumatic brain injury (TBI) is the major cause of death and disability among young adults. In spite of preventive measures, the incidence of a TBI associated with motor vehicle accidents, falls, assault, and high-contact sports continues to be alarmingly high and constitutes a major public health concern. In addition, the recent military operations in Iraq and Afghanistan have resulted in a large number of persons with blast injuries and brain trauma. Taking into account that cognitive and behavioral changes have a decisive influence in the recovery and community reintegration of patients with a TBI, there is a renewed interest in developing systematic studies of the frequency, mechanism, and treatment of the psychopathological alterations observed among these patients.

The mind-brain dichotomy has been on a roller-coaster ride over the past few hundred years. Clinically astute European neuropsychiatrists in the 18th and 19th centuries described various neuropsychiatric disorders based on observations of their patients.

Despite an abundance of studies linking both traumatic experiences and anxiety disorders with eating disorders, relatively little has been reported on the prevalence of associated posttraumatic stress disorder (PTSD) or partial PTSD in patients with eating disorders.

The Psychodynamic Diagnostic Manual1 (PDM) was created by a task force chaired by child psychiatrist Stanley Greenspan, MD, in cooperation with the American Psychoanalytic Association, the International Psychoanalytical Association, the Division of Psychoanalysis of the American Psychological Association, the American Academy of Psychoanalysis and Dynamic Psychiatry, and the National Membership Committee on Psychoanalysis in Clinical Social Work.

From Our Readers

In recent years, we have learned a great deal about posttraumatic stress disorder (PTSD) and its public health implications. From 9/11 to Katrina and the present Iraq war, PTSD has been in the forefront of health concerns and public policy.

It is my great honor and pleasure as a psychiatric educator to teach many excellent medical students and residents. These young and not-so-young men and women are by and large diligent, highly professional, and caring.

Evidence for Use of Neurostimulating Techniques

The adage has it that the road to hell is paved with good intentions. It is evident from this revealing portrait of neurologist Walter Freeman--the originator of the infamous "ice pick" lobotomy--that good intentions without sober analysis can indeed have hellish consequences.

Parkinson disease (PD) is a progressive neurodegenerative disorder affecting 1% of people 65 years and older. The core symptoms include the motor manifestations of tremor, bradykinesia, and rigidity.

The clinical diagnosis of Pick disease can be one of the most difficult facing the neurologist. Those patients found to have lobar atrophy usually present clinically with bouts of irrational behavior, bulimia, marked reductions in speech, abulia, and apathy.

During the past decade, a great deal of research has been undertaken to better understand the pathogenesis of neurodegenerative diseases. Data from stroke models has shown that the semisynthetic tetracycline antibiotic minocycline can mediate neuroprotection in neurodegenerative diseases by inhibiting caspase-1 and inducible nitric oxide synthase (iNOS) activity.

Book Review

Epidemiological studies report a lifetime prevalence rate of 24.9% for (any) anxiety disorder. Feelings of anxiety can also be related to normal fear of pain, loneliness, ridicule, illness, injury, grief, or death. In both these types of situations, anxiety can be difficult to deal with. Consequently, benzodiazepines, which offer almost immediate symptomatic relief for anxiety, can be quite appealing to many persons.

Civilian cases of traumatic brain injury (TBI) account for more than 50,000 deaths annually and represent about 50% of deaths attributed to physical injury. These injuries are a significant medical and socioeconomic burden and represent one of the leading public health problems in the United States. However, thanks to injury prevention and changes in hospital admission practices, a decline of almost 50% in civilian hospitalizations for TBI has been observed since 1980, with many patients now treated on an outpatient basis.

Involuntary Emotional Expression Disorder Often Misdiagnosed and Untreated

In past discussions on brain-computer interfaces (BCIs), parallels were drawn between emerging applications and the idea of the "bionic man." However, a presentation by John P. Donoghue, PhD, during a "Hot Topics" plenary session on May 2 at the 59th Annual Meeting of American Academy of Neurology in Boston suggests that current neural interface technology is much more about the marvels of the human neuron and will than about machinery.

The results of two recent studies suggest that antidepressant medication may have an expanded role in the management of stroke patients. Prophylactic use of antidepressants following stroke appeared in a meta-analysis to be effective in fending off depression, and a short course of antidepressants in a placebo-controlled study was associated with long-term restoration of executive function, independent of depressive symptoms.

The following must be one of the strangest comments I have ever heard on television. An Iraqi businessman uttered it shortly after a wave of missile strikes during the Gulf War. "The rocket flew down my street and took a left," he said in English. It had smashed into its target, a nearby building--leaving his adjacent shop completely undisturbed.

Corticospinal tract (CST) integrity may predict the potential for clinical improvement in chronic stroke patients, according to a recent study. Winston Byblow, MSc, PhD, associate professor and director of the Movement Neuroscience Laboratory in the Department of Sport & Exercise Science at the University of Auckland, Australia, and colleagues used transcranial magnetic stimulation (TMS) and MRI to determine factors that predict functional improvement in a patient's upper limbs.1 In patients with motor-evoked responses (MEPs) to TMS, researchers found that meaningful gains were still possible 3 years after stroke, although the capacity for improvement declined with time. The researchers also created an algorithm to predict functional potential for upper limb recovery in this patient population.

Physicians are often conflicted regarding prescription medications for pain, especially pain complicated by insomnia and anxiety. Concerns that patients may become addicted to medications, exacerbated by limited time available to get to know patients, can lead to underprescribing of needed medications, patient suffering, and needless surgery. At the other extreme, pressure to alleviate patients' distress can lead to overprescribing, needless side effects, and even addiction.

How is conflict of interest-or the perception of it-to be addressed when academia and industry collaborate on drug development? This was the question posed by Cheryl Bushnell, MD, assistant professor of neurology at Duke Medical Center in Durham, North Carolina, who chaired a brainstorming session on the issue at the 9th annual meeting of the American Society for Experimental Neurotherapeutics (ASENT), which took place March 8-10 in Washington, DC.

Essential tremor significantly compromises patients' professional and personal lives.
