The American Psychological Association defines posttraumatic stress disorder (PTSD) as a mental illness that may happen to people who have encountered or witnessed a traumatic event.
A traumatic event includes, but is not limited to, a natural calamity, accident, war, or situations in which you’re threatened with death, sexual violence, or serious injury.
Posttraumatic Stress Disorder (PTSD) was denoted as “shell shock” and “combat fatigue” during the historical World War. Military veterans manifested symptoms of PTSD, which, consequently, led to depression and suicide. People suffering from the illness may have intense, disrupting thoughts and feelings even after the traumatic event has ended. This stress-related disorder may also occur to people regardless of ethnicity, culture, or age.
