Recognizing PTSD and the associated triggers is not an easy task. Each individual has their own triggers, which also bring about a vast possibilities for reaction as a coping mechanism. I have found that if you approach the individual off to the side and away from earshot of the other students, it is easier for the affected individual to relay some of their anxiety to you as the instructor. Veterans are primarily associated with PTSD, but are not the only ones dealing with it. If you are attentive and have had some training on signs to watch for, it makes recognition of it a little easier if you observe the class and how the individuals participate in the classroom.
