Answer:
The correct answer is: Fugue state, dissociative fugue.
Step-by-step explanation:
Fugue state can be understood as a psychiatric disorder in which the individual who suffers from it has amnesia of his/her identity. (Personality, name, life, motivations, goals, likes, needs, wants).
While in a fugue state the person may feel confused, disoriented and may not recall who they are, why they are lost, what's their name, and what they are supposed to be doing.
In this particular case, Tonya was found by the police and she claimed that her name was mary and that she had no clear memory of her life or identity. Her symptoms best illustrate fugue state or dissociative fugue.
