## Core Concept
The question describes a person with symptoms of wandering away from home, loss of recent memory, and depersonalization. These symptoms are characteristic of a specific psychiatric condition that involves sudden, unexpected travel away from home or work, often accompanied by a loss of memory for one's past and partial or complete adoption of a new identity.

## Why the Correct Answer is Right
The symptoms described - wandering away from home, loss of recent memory, and depersonalization - are classic features of **Dissociative Fugue**, now more commonly referred to under the umbrella of **Dissociative Amnesia** with fugue state being a subtype. This condition is part of the dissociative disorders in the DSM-5. It involves sudden travel away from home or work with an inability to recall one's past and confusion about the partial or complete adoption of a new identity.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incorrect because it does not specify the condition described.
- **Option B:** This option is incorrect as it does not match the description provided for the condition.
- **Option C:** Although not directly addressed, any option not aligning with dissociative fugue or amnesia would be incorrect based on the symptoms provided.

## Clinical Pearl / High-Yield Fact
A key point to remember is that **Dissociative Amnesia**, particularly with a fugue state, is often associated with significant psychological trauma. The condition is relatively rare and usually presents with sudden onset. Clinicians must consider underlying psychological issues when diagnosing and managing such cases.

## Correct Answer: D. Dissociative Fugue (or Dissociative Amnesia with Fugue State).
