Acute stress disorder (ASD) is brought upon by experiencing one or more traumatic events, such as the death of a loved one, witnessing an accident or suicide, the threat of death or serious injury, sexual assault. ASD is diagnosed by a person displaying nine or more symptoms of ASD within one month of the traumatic event. If symptoms present for over a month, a mental health professional may evaluate for PTSD. Treatment for ASD may involve CBT, mindfulness, and/or medication. Having forms of support through friends, family, therapist and community members may help a person manage and process their experience and heal.
