What are the categories of symptoms for Acute Stress Disorder?

Acute Stress Disorder (ASD) is characterized by a range of symptoms that arise in response to a traumatic event, typically occurring within three days to one month after the trauma. The correct categorization of its symptoms includes intrusion, mood changes, and dissociation.

Intrusion refers to the involuntary re-experiencing of the traumatic event through flashbacks, nightmares, or distressing memories. Mood changes can manifest as heightened emotional disturbances, which may include feelings of anxiety, sadness, irritability, or an overall change in emotional regulation following the trauma. Dissociation involves disruptions in consciousness, memory, identity, or perception of the environment, which can lead to feelings of detachment or unreality regarding one’s surroundings.

The other options do not accurately encapsulate the recognized symptom categories for ASD. For instance, avoidance and negative cognitive alterations are more closely associated with Post-Traumatic Stress Disorder (PTSD) rather than ASD. Therefore, the correct classification, which includes intrusion, mood changes, and dissociation, highlights the specific and transient symptomatology associated with Acute Stress Disorder.
