“…Post-traumatic stress disorder (PTSD) is a common psychiatric disorder that occurs in some individuals after a traumatic event (Pietrzak, et al, 2012) and is diagnosed by mental health professionals based on the presentation of four symptom clusters -intrusions, avoidance, negative cognitions/mood, and hyperarousal (American Psychiatric Association, 2013).
