Timeline of post-traumatic event symptoms. Post-trauma symptoms can occur at any time following a traumatic event. Symptoms may resolve at any point, spontaneously or with treatment. The presence of symptoms at one point does not necessarily predict future symptoms. Theoretically, interventions to manage symptoms can be applied at any point during or following the traumatic event. Although an ASR can be present up to 30 days following trauma exposure, the first 72 hours are of critical importance for military operations, are the least well- understood or studied, and occur within a period that ASD or PTSD cannot be diagnosed
