Healthy Living: Brain Scan For PTSD

Posted: Updated:

All U.S. soldiers have cleared out of Iraq... and as they head stateside, a lot have trouble leaving the battlefield behind. PTSD is hitting troops hard. At any given time, more than 13 million Americans are affected by it. Now, for the first time ever, there could be a definitive way to find out who has it and help treat it. Robyn Haines has today's Healthy Living.

 

93 year old John Cicha has vivid memories as a POW during WWII. John still lives with post traumatic stress disorder. Psychologist Brian Engdahl says John's reaction to loud noises is a hallmark of the condition. He's heading a two year study on Magnetoencephalography, or MEG to see PTSD.

 

MEG measures magnetic fields in the brain.  It shows patterns of miscommunication that identify PTSD. Another new study testing vets with the imaging system asks them to do different tasks while in an MEG. The brain activity of PTSD vets is then compared to the results of vets without it. The main goal is to define PTSD bio-markers to diagnose it, treat it quickly and track responses to treatment. While Engdahl isn't involved in this particular study, he's excited about MEG's possibilities.

 

The year long MEG study is a collaboration between the VA and researchers at Wake Forest Baptist Medical Center. The project's also testing the technology on vets with traumatic brain injuries.
