Scientists trying to understand traumatic brain injury from bomb blasts are finding the wound more insidious than they once thought.
They find that even when there are no outward signs of injury from the blast, cells deep within the brain can be altered, their metabolism changed, causing them to die, says Geoff Ling, an advance-research scientist with the Pentagon.
The new findings are the result of blast experiments in recent years on animals, followed by microscopic examination of brain tissue. The findings could mean that the number of brain-injured soldiers and Marines — many of whom appear unhurt after exposure to a blast — may be far greater than reported, says Ibolja Cernak, a scientist with the Johns Hopkins University Applied Physics Laboratory....
