fMRI helps finds brain biomarkers linked to severe PTSD
By Erik L. Ridley
Using functional MRI (fMRI) and measurements of skin conductance, researchers have found that combat veterans with severe post-traumatic stress disorder (PTSD) have distinct patterns in how their brains and bodies respond to danger and safety. These brain biomarkers could help identify those at risk of severe PTSD.
