Newly discovered brain injury in vets linked to PTSD

Correct, perhaps this is a jumping off point for them to figure out what changes could be seen in a living brain that would be a marker of this or some type of biopsy testing or gene mapping that shows changes.

last I heard was "Right now, the data on CTE is skewed. Being limited to donated brains means scientists are studying the brains of people whose relatives probably already suspected that something was wrong. One study, for example, showed that playing high school football, was not linked to cognitive problems later in life. So being able to diagnose people while they’re still alive could tell us a lot about how common CTE really is, and it could be crucial for developing treatment for players while they’re alive.

More studies are needed to confirm this method, according to the researchers, and some scientists are skeptical. Lili-Naz Hazrati, a neuroscience researcher at Toronto’s Hospital for Sick Children, told the Chicago Tribune that tau can be found in healthy brains, too. Having a robust way of detecting CTE may still be far off, but we may be one step closer. And if this pans out, it could be a game-changer for athletes."

They should R&D it when they find it and give the resource to the vA
