The most common PTSD symptoms are:
Nightmares of the traumatic event
Avoiding situations that may trigger memories of the traumatic event
Depression
always being over-alert
Troubled sleeping
Increased anger and irritability
Knowing who is more likely to get PTSD after a car accident is almost impossible. Both children and adults can experience the aforementioned symptoms. However, it is known that the longer the person experiences the traumatic event, the more likely they are to develop PTSD. For example, someone that was trapped inside their car during a overturn for a long time, rather than being quickly rescued.
