Acute Stress Disorder is diagnosed 3 days after the occurrence of a traumatic event, and must be at least 3 days after the experiencing trauma. In certain cases, acute stress disorder can eventually lead to post-traumatic stress disorder if symptoms occur over one month. Acute stress disorder can remain constant, or become better or worse for an individual based on stressors occurring in one’s daily life or by experiencing future traumatic instances. Additionally, symptoms can vary across different age ranges and development. Children may experience certain symptoms but be unable to attribute their symptoms to the traumatic event.
