A groundbreaking study on Canadian junior ice hockey uncovers alarming head injury/concussion data and trends that raise many questions about the safety and well being of teenagers and young adults who participate in this popular sport. This is a public health issue that needs to be taken more seriously by players, parents, coaches, and medical professionals. At stake is something more important than winning a game - the present and future health of thousands of young athletes.
Most people have habits that guide them through daily life — for example, their path to work in the morning, or their bedtime routine. The brain patterns that drive this behavior are not well-understood, but a new study from MIT’s McGovern Institute for Brain Research shows that habit formation appears to be an innate ability that is fine-tuned by experience — specifically, the costs and rewards of certain choices.
Scientists are closer to solving one of the many mysteries of multiple sclerosis and other demyelinating diseases, thanks to a recent study conducted at the Salk Institute for Biological Studies. The research revealed a previously unknown connection between two ion channels, which, when misaligned, can cause the many bizarre symptoms that characterize the condition.
Special eye-gaze technology now being used in the Department of Neurology at The Children’s Hospital at Montefiore (CHAM) is revealing the hidden, inner world of children who have Rett Syndrome, a rare and severe autism spectrum disorder that primarily affects little girls.
As anyone who as ever picked up a guitar or a tennis racket knows, precise timing is often an essential part of performing complex tasks. Now, by studying the brain circuits that control bird song, MIT researchers have identified a “chain reaction” of brain activity that appears to control the timing of song.
In a report published in the Oct. 20 issue of Science Translational Medicine, researchers at NewYork-Presbyterian Hospital/Weill Cornell Medical Center say animal and human data suggest gene therapy to the brain may be able to treat patients with major depression who do not respond to traditional drug treatment.
A dozen new epilepsy drugs are giving doctors and patients more options, but making treatment decisions more complex, a Loyola epilepsy specialist reports in the journal Neurologic Clinics.
For the first time, researchers have discovered a disease mechanism that links hereditary amyotrophic lateral sclerosis and the more common "sporadic" form of ALS -- and points to a possible therapeutic target.
Motherhood may actually cause the brain to grow, not turn it into mush, as some have claimed. Exploratory research found that the brains of new mothers bulked up in areas linked to motivation and behavior.
Chronic depression is an adaptive, reparative neurobiological process gone wrong, say two UC San Diego School of Medicine researchers, positing in a new theory that the debilitating mental state originates from more ancient mechanisms used by the body to deal with physical injury, such as pain, tissue repair and convalescent behavior.
Because of impairments in their insulin sensitivity, obese individuals demonstrate different brain responses than their normal-weight peers while completing a challenging cognitive task, according to new research by psychologists at The University of Texas at Austin.

Eleven years after the first edition, a new edition of the Sturge-Weber Syndrome textbook has been published by the Sturge-Weber Foundation in New Jersey. Co-author E. Steve Roach, MD, is chief of Neurology and vice-chair of Pediatrics at Nationwide Children’s Hospital.
New research provides evidence of the vicious cycle created when an obese individual overeats to compensate for reduced pleasure from food.
New research shows that an intravenous (IV) treatment may cut a person’s risk of dying from bacterial meningitis. The research is published in the September 29, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology. The treatment is called dexamethasone.
Tufts biologists have regenerated spinal cord and muscle by using a drug cocktail to trigger an influx of sodium ions into injured cells. This approach requires no gene therapy and can be administered after injury has occurred. The treatment applies most directly to spinal cord repair and limb loss. Proof of principle may apply to many tissues.
Fizzy beverages light up same pain sensors as mustard and horseradish, a new study shows. So why do we drink them?

Chronic subdural hematoma is a frequently encountered problem in neurosurgical practice and the perception is that it is a benign disease, with easy-to-treat lesions. Research showed that the mortality rate increased considerably at 6-month and 1-year follow-up, after what was considered successful treatment. The authors liken the continued increased mortality following treatment of CSDH to the similar and widely reported phenomenon in patients who have undergone successful surgery for hip fracture, surmising that CSDH unmasks underlying medical conditions and exacerbates them.
