Here's a novel idea, given that American parents send almost 4 million of their children out to play tackle football every year, despite mounting concerns about youth concussions: Maybe the helmets their kids wear should be tested and ranked on how well they prevent concussion. A study to be presented at a meeting of the American Academy of Neurology attempts to do exactly that, comparing 10 of the most widely used football helmets in drop tests designed to measure the kinds of forces that are most likely to result in concussion.

Scientists have used a simple training program to break through what was believed to be a fundamental limitation of the human brain - the ability to perceive two items when they are presented in rapid succession, less than half a second apart. The findings suggest new treatments for those with attentional deficits following a brain injury or during the progression of a neurodegenerative disease. They could also lead to a way for people with normal attention to perceive the world better.

Albert Einstein had a colossal corpus callosum. And when it comes to this particular piece of neural real estate, it's pretty clear that size matters. Chances are, that brawny bundle of white matter cleaving the Swiss physicist's brain from front to back is part of what made his mind so phenomenally creative. The corpus callosum carries electrical signals between the brain's right hemisphere and its left. Stretching nearly the full length of the brain from behind the forehead to the nape of the neck, the corpus callosum is the dense network of neural fibers that make brain regions with very different functions work together.

Michael Butcher has applied for at least 25 jobs since injuries he suffered in Iraq forced him to leave the Army three years ago. "I was even turned down by McDonald's," said the 29-year-old San Diego native. The military is known for developing leadership, adaptability, loyalty and teamwork. But Butcher said when he tells employers he needs time off to see therapists for post-traumatic stress disorder and a brain injury, they don't call back. "They think you are mental," he said.

New research from Canada has found that roughly 1 in 5 adolescents has probably suffered a traumatic brain injury--a figure that suggests severe concussion among children and adolescents may be far more common than has been estimated. The new study also hints at a troubling link between a history of traumatic brain injury and poorer grades, underage drinking and use of illicit drugs. In Ontario, Canada, 62% of students in grades seven through 12 anonymously completed a computerized questionnaire administered during the school day, which gauged their drug and alcohol consumption patterns and a wide range of health-related behaviors.

Reporting from Glendale, Ariz. — "I look completely normal, right?" a completely normal-looking Taylor Twellman says. It's something he asks often, and the response is always the same: nodding heads, words of affirmation, smiles. In reality, though, Twellman is far from normal. Three and a half years ago, the then-New England Revolution forward and former Major League Soccer most valuable player was accidentally punched in the jaw by Galaxy goalkeeper Steve Cronin while scoring on a header.

Laura Gagliardi awoke from a coma on her 17th birthday, three months after she suffered traumatic brain injury in a car accident. It was an event her family and doctors had hoped for but did not expect. Gagliardi had arrived at the hospital unconscious and unresponsive. But rather than battling to keep the teenager out of a coma, Dr.

In the wake of a traumatic brain injury, a victim may have more to worry about than lingering headaches, dizziness or inability to concentrate: A new study finds that the risk of ischemic stroke -- in which blood flow to the brain is blocked or reduced -- rises in the years that follow. That finding, published this week in the journal Neurology, may help explain the incidence of stroke in patients under 65 and in patients without some of stroke's known risk factors, such as hypertension, Type 2 diabetes or atrial fibrillation.
