Study Of Helmets With Face Shields

Study Of Helmets With Face Shields.
Adding expression shields to soldiers' helmets could truncate brain damage resulting from explosions, which account for more than half of all combat-related injuries unremitting by US troops, a new study suggests. Using computer models to simulate battlefield blasts and their chattels on brain tissue, researchers learned that the face is the strongest pathway through which an explosion's pressure waves reach the brain. According to the US Department of Defense, about 130000 US repair members deployed in Afghanistan and Iraq have sustained blast-induced injurious brain injury (TBI) from explosions.

The addition of a face shield made with transparent armor statistics to the advanced combat helmets (ACH) worn by most troops significantly impeded direct curse waves to the face, mitigating brain injury, said lead researcher Raul Radovitzky, an confidant professor at the Massachusetts Institute of Technology (MIT). "We tried to assess the physics of the problem, but also the biological and clinical responses, and bind it all together," said Radovitzky, who is also associate chief honcho of MIT's Institute for Soldier Nanotechnologies. "The key thing from our point of view is that we gnome the problem in the news and thought maybe we could make a contribution".

Researching the issue, Radovitzky created computer models by collaborating with David Moore, a neurologist at the Defense and Veterans Brain Injury Center at Walter Reed Army Medical Center in Washington, DC Moore old MRI scans to simulate features of the brain, and the two scientists compared how the brains would reply to a frontal destroy wave in three scenarios: a head with no helmet, a head wearing the ACH, and a prime minister wearing the ACH plus a face shield. The sophisticated computer models were able to fuse the force of blast waves with skull features such as the sinuses, cerebrospinal fluid, and the layers of gray and whey-faced matter in the brain. Results revealed that without the face shield, the ACH slightly delayed the burst wave's arrival but did not significantly lessen its effect on brain tissue. Adding a face shield, however, considerably reduced forces on the brain.

Even Easy Brain Concussion Can Lead To Serious Consequences

Even Easy Brain Concussion Can Lead To Serious Consequences.
Soldiers who experience submissive brain injuries from blasts have long-term changes in their brains, a meagre new study suggests. Diagnosing mild brain injuries caused by explosions can be challenging using prevailing CT or MRI scans, the researchers said. For their study, they turned to a unique type of MRI called diffusion tensor imaging. The technology was used to assess the brains of 10 American veterans of the wars in Iraq and Afghanistan who had been diagnosed with modest traumatizing brain injuries and a comparison group of 10 people without brain injuries.

The average occasion since the veterans had suffered their brain injuries was a little more than four years. The researchers found that the veterans and the resemblance group had significant differences in the brain's white matter, which consists mostly of signal-carrying nerve fibers. These differences were linked with publicity problems, delayed memory and poorer psychomotor examination scores among the veterans. "Psychomotor" refers to movement and muscle ability associated with intellectual processes.
