My ability to sit peacefully day after day and write about health or enjoy my family owes more than I’ll ever know to the hard work and sacrifice of generations of American men and women who served in the Armed Forces. On behalf of my colleagues at Harvard Health Publications: Thank you for your service.
One of the challenges faced by many servicemen and servicewomen returning from war is post-traumatic stress disorder, or PTSD.
In a nutshell, post-traumatic stress disorder is a lasting and exaggerated reaction to a terrifying or life-threatening event. It makes a person feel like he or she is living through the event over and over again. PTSD shows itself in three main ways:
Re-experiencing. People with PTSD mentally relive the triggering trauma in daytime flashbacks, nightmares, or inescapable thoughts about the event. Sights, sounds, smells, or other stimuli can bring the event to life.

Flashbacks are vivid, recurring, intrusive, and unwanted mental images of a past traumatic experience. They are a sine qua non of post-traumatic stress disorder (PTSD). Although drugs and cognitive behavioral interventions are available to treat PTSD, clinicians would prefer to utilize some sort of early intervention to prevent flashbacks from developing in the first place.
Well, researchers at Oxford University appear to have found one. Remarkably, all it takes is playing Tetris. Yes, Tetris!
The team responsible for the discovery was led by Emily Holmes. The writeup appears in the November issue of PLoS ONE. Holmes and colleagues had reasoned that the human brain has a limited capacity to process memories, and that memory consolidation following a traumatic experience is typically complete within six hours after the event. Holmes’ team also knew that playing Tetris involved the same kind of mental processing as that involved with flashback formation. So they figured if they had people play Tetris during that six-hour window after the traumatic event, it might interfere with memory consolidation of the traumatic experience. That, in turn, would reduce or eliminate the flashbacks. The idea worked like a charm. Read more »
