Neuroplasticity enables the brain to adapt and recover after injury, emphasizing the importance of multidisciplinary rehabilitation for effective healing.
Battlefield TBI: Blast and Aftermath
August 1st 2007Civilian 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.

Mind Over Matter: BCIs on the Fast Track for the New Age
July 1st 2007In 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.

Antidepressants Evidence Salutary Effects for Stroke Patients
July 1st 2007The 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 Therapeutic Potential of Neural Stem Cells
May 1st 2007The 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.

Stroke Researchers Look to Corticospinal Tract to Identify Rehabilitation Potential
May 1st 2007Corticospinal 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.

Reducing the Risk of Addiction to Prescribed Medications
April 15th 2007Physicians 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.

Experts Wrangle With Conflict of Interest in Clinical Trials
April 1st 2007How 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.

When I was young and attended church services with the family, the sermons of a certain priest, who was a historian, consisted of anecdotes about desperation and compassion that occurred in such places as Nazi concentration camps, Hell's Kitchen or the Bowery in Depression-era New York, or Dickens-like orphanages somewhere. At the end of his anecdote, the priest would dolefully lilt, Examine your own conscience. It was the point during the sermon when a person might startle awake after nodding off.

Raising the Bar on ALS Care: It's Possible and Appreciated
March 1st 2007Presenting a diagnosis of amyotrophic lateral sclerosis (ALS) is one of the most difficult tasks that a neurologist may have to undertake. Despite the tragic quality of the news, experts in ALS care are exhorting fellow neurologists not to give up on patients in whom ALS is diagnosed.

The Clinical Management of Amyotrophic Lateral Sclerosis
March 1st 2007Amyotrophic lateral sclerosis (ALS) is a progressive, debilitating, fatal disease that involves degeneration of upper and lower motor neurons. Patients often initially present with limb or bulbar weakness, atrophy, and spasticity, followed by progressive loss of ambulation and, ultimately, respiratory failure, which is the most common cause of death.

Melanoma and PD: New Findings Absolve Levodopa, Warrant Cancer Screening
February 1st 2007The connection between Parkinson disease (PD) and melanoma is becoming increasingly apparent, leading some researchers to call for increased melanoma screening in the PD population. In addition, researchers are disproving previous theories that levodopa may be implicated in the link between melanoma and PD.

Melanoma and PD: New Findings Absolve Levodopa, Warrant Cancer Screening
February 1st 2007Patients with PD may be at more than twice the risk for the development of malignant melanoma than the general population, according to research by John M. Bertoni, MD, PhD, professor and chair of the Department of Neurology at Creighton University, Omaha, and colleagues.1 He presented the results of this research at the American Neurological Association's 131st Annual Meeting this past October in Chicago.

To evaluate the degree to which newer antipsychotic agents are implicated in parkinsonism and whether drug-induced parkinsonism (DIP) is being adequately recognized, Christine D. Esper, MD, clinical instructor in neurology, and Stewart A. Factor, DO, professor of neurology at Emory University in Atlanta, performed a retrospective review of 354 consecutive patients in whom parkinsonian symptoms were newly diagnosed at a movement disorders clinic in 2004-2005

Is the DSM the Bible of Psychiatry?
December 1st 2006A discussion of the intellectual, social, and historical similarities and differences between sacred texts and the DSM would require a full-length book, but we will concentrate here on 5 main aspects: controversy, communication, interpretation, change, and power.

Depression in Parkinson Disease
November 1st 2006Prevalence of depression in PD is estimated to range from 7% to 76%. The variation is largely attributed to the diversity of the populations under study, differences in the definition of depression, and the fact that some studies used point prevalence and other studies used monthly prevalence. Also, the prevalence of depression varies with fluctuations of cognitive status and other comorbidities that are an integral part of PD.

Depression in Patients With Alzheimer Dementia
November 1st 2006Alzheimer dementia (AD) represents a profound global health concern. By the year 2050, the prevalence of AD in the United States is expected to reach 15 million. At present, there are 4.5 million cases in the United States, which equals an estimated cost of $100 billion each year in medical and family expenses.

Pinpointing the Cause of Non-Alzheimer Dementia
November 1st 2006Many physicians, including psychiatrists, may shy away from seeing elderly patients with symptoms of dementia because they imagine that there are a large number of alternative diagnoses and that differential diagnosis is complicated. In fact, however, the number of possible diagnoses in most situations is relatively small and the diagnosis of dementia in older patients is certainly feasible in primary care psychiatry.

Cultural Issues in the Emergency Setting
November 1st 2006The setting of a fast-paced emergency department (ED) or psychiatric emergency service makes it especially difficult to sensitively elicit and address an individual patient's needs and concerns. When considering the myriad differences in culture that come into play between a patient and a psychiatrist or other mental health care clinician, optimal diagnosis and treatment can be even more challenging, as the cases described here illustrate. The important influence of culture cannot be stressed enough. Taking the time to understand "where the patient is coming from" can prevent an already stressful, highly emotionally charged situation from becoming even more convoluted.
