People who are more vulnerable to post traumatic stress disorder (PTSD) have a more sensitive personality than those who do not develop this disorder.
PTSD occurs when a person goes through some type of trauma, causing suffering that impacts on various aspects of life. Post traumatic stress can occur from experiences such as violence, accidents, natural disasters and disease diagnosis.
Therefore, people who are more vulnerable to developing PTSD have a more sensitive personality than those who do not develop the disorder despite negative experiences.
Some symptoms associated with PTSD are recurrent reminders of the adverse experience, physical symptoms, and negative emotions.
It is necessary for the individual who identifies some symptoms related to trauma to seek professional help to identify the appropriate treatment to resolve this disorder.
