TBI and suicide link in soldiers
Unless you live under a rock, you've likely heard about the large number of soldiers returning from war with traumatic brain injuries (TBIs).
Whereas doctors used to believe that you had to be right next to an explosion (or in a Humvee accident, etc.) to get a head injury, we now know that soldiers can be quite a distance away and get TBIs from blast shockwaves.
Which is what makes it even scarier that there's a strong link between TBIs and suicide risk. In fact, not only does the incidence of suicidal thoughts or behaviors increase with the number of TBIs a soldier experiences, but also the severity of symptoms (think headache, depression, etc.).
In a recent study of 161 military personnel who were suspected to have head injuries, researchers at the National Center for Veterans Studies in Salt Lake City reported these stats regarding incidence of lifetime suicidal thoughts or behaviors and suicidal ideatio within the past year:
No TBIs = 0 %
One TBI = 6.9%
Multiple TBIs = 21.7%
