A researcher is developing a simple new way to test for PTSD using samples of saliva. This would allow doctors to prevent PTSD from even developing and only treat those that actually suffer from PTSD. This would save a huge amount of time and resources and directly help soldiers suffering from PTSD. The study was conducted on mice as well as people and researchers are moving forward with its clinical trials. By developing this noninvasive test, medical professionals hope to be able to accurately diagnose PTSD from the start, leading to faster recoveries for soldiers.
