Post-traumatic stress disorder (PTSD)
An event that is traumatic or terrifying can lead to PTSD, a mental health disorder. An assault, an attack, a natural disaster, a serious accident, are all examples of traumatic events. PTSD can cause nightmares or flashbacks during which one relives the experience. These are vivid memories of the event that evoke fear. These can cause problems with sleep.
The effects of PTSD can vary from person to person. It can have an adverse effect on your work and school performance, as well as on your relationships with friends and family.
