Key Features of Dissociative Amnesia:

1. Memory Loss: Sudden, extensive inability to recall autobiographical information (e.g., name, address, past experiences).

2. Localized Amnesia: Most common; inability to remember events from a specific period (e.g., after a car crash).

3. Selective Amnesia: Some parts of a traumatic event are forgotten, while others are remembered.

4. Generalized Amnesia: Rare; complete loss of identity and life history.

5. Systematized Amnesia: Loss of memory for a specific category of information (e.g., all memories about a person or childhood abuse).

6. Dissociative Fugue (Specifier): In some cases, the person may travel or wander in a confused state and may assume a new identity temporarily.
