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.

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.

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.

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.

Heading the ball is a key soccer skill, but a new study finds that players who headed the ball frequently were more likely to suffer brain injury and damage their memory than their fellow players who were a little less headstrong, so to speak. While sports like football (the American variety) and ice hockey garner most of the attention when it comes to concussions and other forms of traumatic brain injury (TBI), soccer is an intense physical sport for which the head can be as important as the foot.
