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.

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.

Recent imaging studies have shown that patients with autism spectrum disorders (ASDs) who were presented with images of human faces had lower responses in amygdala activity than controls. These studies strengthen the connection between the amygdala and the abnormal social-emotional behavior seen in patients with ASDs, said Chris Ashwin, PhD, senior research associate at the Autism Research Centre in the Department of Psychiatry at the University of Cambridge, UK.

PD is a common and challenging neurodegenerativemotor disorder, affecting at least a half millionpersons in the United States, according to the NationalInstitute of Neurological Disorders and Stroke. Withthe aging of the population, incidence is expected toincrease.

Patients 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

In a recent article on genetic counseling in psychiatry, Christine Finn, MD, and Jordan W. Smoller, MD, ScD, noted that family and twin studies have documented the familiality and heritability of schizophrenia, bipolar disorder, major depression, anxiety disorders, autism, attention-deficit/hyper- activity disorder (ADHD), and Tourette syndrome, among others, and that molecular genetic studies have begun to identify possible susceptibility loci for several of these disorders, most notably schizophrenia.

It may come as a surprise, especially given its low repute in the popular mind since the 1980s, but electroconvulsive therapy (ECT) is making a comeback, both as a recommended treatment for depression and in public awareness.

Prevalence 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.

Effective antiepileptic therapy depends on balancing seizure control and tolerability, said Manoj Raghavan, MD, PhD, during a presentation at the midyear meeting of the American Epileptic Society in Chicago this past June. Tolerability places a ceiling on how far you can go in controlling seizures using medications alone, he commented.
