Brain imaging technology advances at a rapid pace. A new process, called "high definitiion fiber tracking," reveals areas of brain injury with more exactness than standard scans such as CT & MRI and even the newer DTI method.
Millions of Americans suffer a traumatic brain injury, or TBI, each year. Most TBIs are concussions or
The popularity of ATVs has grown tremendously over the years, reaching 9.5 million vehicles in 2007. Accordingly, the rate of traumatic brain and spinal injuries resulting from ATV accidents has also risen, especially in children. Between 1982 and 2007, nearly 9000 riders died in ATV accidents and approximately 40% of them were children under age
Following a recent threat by Air Canada to pull its sponsorship dollars, the NHL announced a revision of the NHL Protocol for Concussion Evaluation and Management. The Protocol now requires:
Array tomography is a state-of-the-art imaging system invented by Stanford University researchers. It allows researchers to count the myriad connections between nerve cells, as well as to catalog those connections’ surprising variety.
A typical healthy human brain contains about 200 billion nerve cells, or neurons, linked to one another via hundreds of trillions of tiny
“Second Impact Syndrome” refers to mild brain injuries suffered repeatedly within a short period (hours, days, or weeks). Although all brain injuries are serious, second impacts can be catastrophic or even fatal. The American Academy of Neurology has developed guidelines for deciding when it is safe to return to play after a first injury.
When a head is twisted violently, such as in a car crash, microscopic brain structures, called axons, can tear. The damage to the brain is a called a "diffuse axonal injury," or DAI. When the axons tear, chemicals that were contained in those structures can leak into the brain tissue. The torn axons and chemicals in the brain tissue
An impact on one side of the head can cause the pudding-like substance of the brain to hit the inside of the skull and then bounce back and hit the inside of the skull on the opposite side of the head. When the brain suffers two injuries from one impact, it is called a
