PTSD has been around since war began, and it is often associated with the trauma that soldiers had experienced in battles. However, it could also be apart of other problems that cause injury. PTSD stands for post-traumatic stress disorder. Another disorder similar to PTSD is called ASD, and it stands for acute stress disorder.
Even though the similarities include mainly the results by getting help, many symptoms are not experienced by both ASD and PTSD. Therefore, the symptoms have some variation when comparing PTSD and ASD. PTSD seems to have the symptoms of feeling that time is slowing down, more self-destructive activities, hypervigilance, and negative beliefs, whereas ASD does not have those symptoms. However, they have more nightmares than PTSD.
