Heavily traumatized people such as refugees fleeing war, torture and natural catastrophes may not necessarily develop posttraumatic stress disorder (PTSD), a new study reveals.
Dr Simon Hanslmayr, Reader in Cognitive Neuroscience at the University of Birmingham, commented: ”Difficulties experienced by people with severe PTSD symptoms when attempting to suppress bad memories is linked to the ability to regulate gamma frequency brain activity.
”This novel biomarker could help identify risks posed to PTSD patients by memory suppression techniques and assist in adapting and developing psychotherapeutic methods. Our study certainly raises concerns about unwary use of memory suppression in treating PTSD sufferers.”
