In their first year of life, babies who will go on to develop autism already show different brain responses when someone looks at or away from them. Although the researchers are careful to say that the study, reported online on January 26 in the Cell Press journal Current Biology, is only a first step toward earlier diagnosis, the findings do suggest that direct brain measures might help to predict the future development of autism symptoms in infants as young as six months.

Neurologists should ask patients about abuse
A new position statement issued by the American Academy of Neurology calls on neurologists to begin screening their patients for abusive or violent treatment by family, caretakers or others. The position statement is published in the January 25, 2012, online issue of Neurology.. Types of abuse include elder abuse, child abuse, sexual abuse, financial abuse, emotional abuse, bullying, cyberbullying and violence.
Study: Men at higher risk for mild memory loss than women
Men may be at higher risk of experiencing mild cognitive impairment (MCI), or the stage of mild memory loss that occurs between normal aging and dementia, than women, according to a study published in the January 25, 2012, online issue of Neurology.
Optical Illusion experiment shows higher brain functions involved in pupil size control
(Medical Xpress) — We all know that our pupils contract when our eyes are exposed to increases in the brightness of light. The reason is to both protect the delicate inner workings of our eyes and to help provide for optimum viewing based on available light. But we also know that our pupils dilate, or become larger when we are aroused, regardless of the reason, which means that pupil size is not always just a reaction to lighting conditions. Now, new research by Bruno Laeng and Tor Endestad from the Department of Psychology at the University of Oslo, shows that our pupils also react based on what we think we see sometimes, rather than what is actually there. In their paper, published in the Proceedings of the National Academy of Sciences, the two show that pupil constriction occurs when viewing an optical illusion that at first makes us believe one image is brighter than another, when in reality, they are the same.
New deep brain stimulation device shows promising results
(Medical Xpress) — A multi-site study of a new deep brain stimulation device for people with Parkinsons disease has found the device to provide benefits to patients, potentially paving the way for unprecedented competition in the area of neurostimulation technology.
