According to a BBC article, anyway. http://news.bbc.co.uk/2/hi/health/7813637.stm Apparently they showed some subjects traumatic video, then made them play Tetris. Flashbacks to the traumatic memories were reduced.
Someone in another IRC channel I hang out in actually linked this to me earlier. My response: Clearly they didn't play Death mode.

"Reduce trauma"? What the eff are you talkin' about? *plays TA Death* *flashbacks to horrible TA death runs, which recursively triggers more horrible flashbacks*
