Lifetime PTSD is associated with impaired emotion recognition in veterans and their offspring

PTSD is associated with emotion dysregulation. Studies have found inconsistent impaired facial emotion recognition ability (ERA) in patients with PTSD and intergenerational transmission of PTSD has been reported, although no studies exist regarding ERA. Our objective was to characterise the facial ERA of a group of traumatised war veterans with, and without lifetime PTSD, and also of their respective adult offspring. Sixty-one veterans with, and without lifetime PTSD and 73 offspring were tested for ERA of seven basic facial emotions expressions, 40 years after veterans had been exposed to war-related trauma. Veterans with lifetime PTSD showed impairment of recognition of all emotions, irrespective of the type, when compared with veterans without PTSD. This result was maintained after adjusting for potential confounders-including depressive symptoms. Offspring of veterans with lifetime PTSD also showed impaired recognition of all emotions, including after adjustment for the same variables. Offspring of veterans with lifetime PTSD also showed specific impairment in recognising the emotions of happiness and disgust. These results confirm that PTSD has negative effects with regards to emotion regulation and also on the next generation. This could result in this population being at increased risk of suffering from relationship problems and psychopathology.
