Post-Traumatic Stress Disorder (PTSD) is a mental health condition that arises following the experience of one or more traumatic events. These incidents may include actual or perceived threats to life, serious injuries, instances of sexual violence, involvement in warfare—whether as a combatant or civilian—natural disasters, man-made catastrophes, or significant vehicular accidents.
While individuals may exhibit varying clinical manifestations of PTSD symptoms, a majority observe notable shifts in their cognitive processes, emotional states, and behaviours. In particular, they might encounter intrusive thoughts, engage in avoidance behaviour, experience negative mood changes, and show heightened brain arousal and activity.
In some cases, symptoms of PTSD may not manifest right away, but they can emerge within the first three months after exposure to trauma.
