Is the U.S. Army overhyping its 'breakthrough' brain-injury test?
Army brass declared a triumph over diagnosing traumatic brain injuries last week, hyping a simple new blood test they say can catch the trauma before it becomes more severe, before telltale symptoms manifest, or before troops sustain a second concussion. But with one small study and a history of expensive, underperforming "breakthrough" treatments for brain injuries, this latest test still has a ways to go before it'll be worth bragging about. "This is a breakthrough," Col. Dallas Hack, director of the Army's Combat Casualty Care Research Program, told CNN. "It can make a significant benefit for mankind."
