What is the primary characteristic of Dissociative Amnesia with Fugue?

Dissociative Amnesia with Fugue is defined primarily by a sudden, unexpected travel away from home or customary work locations, accompanied by an inability to recall one’s past, particularly the personal history that is integral to the individual. This condition is characterized by memory loss that is not due to a medical condition or substance use, and it typically involves a disruption in identity, where the individual may assume a new identity while they are away. This travel is spontaneous and often occurs without prior planning.

In this context, the emphasis on "sudden travel with memory loss" accurately captures the essence of the disorder, differentiating it from other psychiatric conditions characterized by anxiety, depression, or nightmares. The other options pertain to symptoms that can occur in various psychiatric disorders but do not specifically define Dissociative Amnesia with Fugue. Therefore, the primary feature of this condition is indeed the combination of unexpected travel and significant gaps in memory surrounding the personal identity and background.
