• A. Dissociative Amnesia
• B. Depersonalization/Derealization Disorder
• C. Acute Stress Disorder
• D. Posttraumatic Stress Disorder

Answer: (A)

The key idea is that this disorder centers on memory loss for personal life details. Dissociative amnesia is defined by an inability to recall important autobiographical information, usually after a traumatic or stressful event, that goes beyond ordinary forgetfulness and is not due to another medical condition or substance. This memory gap can be limited to a specific event or span a broader portion of the person’s life, and it may occur with or without other dissociative symptoms. Other disorders described here involve different core features—such as a sense of unreality in depersonalization/derealization, or the range of trauma-related symptoms like intrusion, avoidance, and hyperarousal found in acute stress disorder and PTSD—so they do not center on autobiographical memory loss. Therefore, the statement correctly identifies dissociative amnesia.
