Which two disorders are classified under stress-related and trauma-related disorders?

Post-traumatic Stress Disorder (PTSD) and Acute Stress Disorder (ASD) are both classified under stress-related and trauma-related disorders due to their direct associations with exposure to traumatic events and the psychological impacts stemming from such experiences.

PTSD is characterized by persistent re-experiencing of trauma, avoidance of trauma-related stimuli, negative alterations in cognition and mood, and marked changes in arousal and reactivity following exposure to a traumatic event. This disorder can emerge after a traumatic experience, leading to significant distress and impairment in social, occupational, or other important areas of functioning.

Acute Stress Disorder shares many symptoms with PTSD but occurs in the immediate aftermath of a traumatic event, typically within three days to one month following the trauma. Symptoms can include intrusive memories, negative mood, dissociation, avoidance, and arousal. If these symptoms persist beyond a month, a diagnosis of PTSD may then be appropriate.

These two disorders reflect the psychological response to trauma and stress, highlighting the impact of severe stressors on mental health. The other disorders listed in the options do not fit this specific classification as they arise from different etiological factors and do not solely stem from trauma exposure.
