New findings on TBI causes

Ohio personal injury accident victims may want to be aware of new findings that contribute to the understanding of traumatic brain injuries. While the exact mechanics of TBIs remain unknown, scientists continue to attempt to find out in an effort to prevent such long-lasting injuries from occurring. One team of researchers believes that pressure waves caused by traumatic events, such as explosions, create small bubbles in the brain. These bubbles may lead to the type of damage that results in a TBI.

A Brown University researcher presented his team's TBI findings at the American Physical Society's Division of Fluid Dynamics meeting. According to the researchers, concussions most often result from head impacts in events such as contact sport collisions or auto accidents. Such trauma can kill individual neurons, but even stronger pressure waves may have other effects. Researchers grew neurons in a mix of proteins to mimic the surroundings of a brain. The neurons were not as closely packed as they would be in a brain, which made them easier to examine.

Researchers found a way to mimic the pressure waves of specific types of trauma with a powerful laser of adjusting intensity. The laser intensity in one experiment resulted in a bubble of steam that collapsed once the laser was off and caused the desired cellular damage. The research team suggests that the bubbles formed from such trauma cause water vapor to form inside the brain, degrading its delicate tissues. Future research is expected to determine if the development of bubbles, otherwise known as cavitation, leads to a distinct type of brain damage.

A head injury can have lasting medical consequences for the victim. Those who have suffered financial losses due to an inability to work and extensive medical bills as a result of an injury caused by the negligence of another party may want the assistance of a personal injury attorney in seeking compensation for such losses from the at-fault party.
