Montreal, October 3, 2012 – With immigration on the rise, the use of English as a second language is sweeping the world. People who have grown up speaking French, Italian, Mandarin or any other language are now expected to be able to communicate effectively using this new lingua franca. How understandable are they in this second language?

EAST LANSING, Mich. — Genetics may make some women more vulnerable to the pressure of being thin, according to a paper led by Michigan State University researchers that is sure to make biologists cringe.

From size-zero models to airbrushed film stars, thinness is portrayed as equaling beauty across Western culture, and it's an ideal often cited as a cause of eating disorder symptoms in young women.

PROVIDENCE, R.I. – Epileptic and psychogenic nonepileptic seizures (PNES) may look similar, but actually have different causes and treatments. Up to 20 percent of patients diagnosed with epilepsy actually have PNES, which are not treated by antiepileptic drugs (AEDs). According to a new study by Rhode Island Hospital researcher W. Curt LaFrance Jr., M.D., M.P.H., director of neuropsychiatry and behavioral neurology, increasing access to video electroencephalography (video-EEG) may aid in distinguishing between epilepsy and PNES.

Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found. By altering activity of the macrophage cells that respond to injuries, researchers dramatically increased the rate at which nerve processes regrew.

Chevy Chase, MD— Low serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) are associated with Alzheimer's Disease in men, but not women, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Low blood levels of vitamin D are associated with an increased number of brain lesions and signs of a more active disease state in people with multiple sclerosis (MS), a new study finds, suggesting a potential link between intake of the vitamin and the risk of longer-term disability from the autoimmune disorder.

CHICAGO --- It was a study everyone thought couldn't be done -- tracking, locating and interviewing nearly 2,000 youths up to five years after they were released from juvenile detention in Chicago to assess their mental health.

CHICAGO – A study of juveniles detained in Chicago suggests that more than 45 percent of males and nearly 30 percent of females had one or more psychiatric disorders with associated impairment five years after detention, according to a report published in the October issue of Archives of General Psychiatry, a JAMA Network publication.

"Betcha can't eat just one!" For obese people trying to lose weight, the Lays potato chip advertising slogan hits a bit too close to home as it describes the daily battle to resist high calorie foods.

But new research by Terry Davidson, director of American University's Center for Behavioral Neuroscience, indicates that diets that lead to obesity—diets high in saturated fat and refined sugar—may cause changes to the brains of obese people that in turn may fuel overconsumption of those same foods and make weight loss more challenging.

It is widely believed that adolescents engage in risky behaviors because of an innate tolerance for risks, but a study by researchers at New York University, Yale's School of Medicine, and Fordham University has found this is not the case.

When people – and monkeys – look at faces, a special part of their brain that is about the size of a blueberry "lights up." Now, the most detailed brain-mapping study of the area yet conducted has confirmed that it isn't limited to processing faces, as some experts have maintained, but instead serves as a general center of expertise for visual recognition. Neuroscientists previously established that this region, which is called the fusiform face area (FFA) and is located in the temporal lobe, is responsible for a particularly effective form of visual recognition.

Diseases that progressively destroy nerve cells in the brain or spinal cord, such as Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS), are devastating conditions with no cures.

A seemingly unique part of the human and mammalian brain is the neocortex, a layered structure on the outer surface of the organ where most higher-order processing is thought to occur. But new research at the University of Chicago has found the cells similar to those of the mammalian neocortex in the brains of birds, sitting in a vastly different anatomical structure.

PHILADELPHIA — Whether human or baboon, it helps to have friends. For both species, studies have shown that robust social networks lead to better health and longer lives. Now, a team of University of Pennsylvania researchers has helped show that baboon personality plays a role in these outcomes, and, like people, some baboons' personalities are better suited to making and keeping friends than others.

BOSTON, Mass.-- Fluoxetine was the first drug approved by the FDA for major depressive disorder (MDD) in children and adolescents, and to this date, it remains one of only two selective serotonin reuptake inhibitors (SSRIs) registered for treatment of MDD in children and adolescents, despite reports that indicate this class of drugs is associated with side effects, such as agitation, hostility and aggression.
