In which Dissociative Disorder does an individual have an inability to form new memories after the condition producing the amnesia occurs?

Anterograde amnesia is characterized by the inability to form new memories following the onset of the amnesia-inducing condition. This means that while memories prior to the event or condition may remain intact, the individual struggles to retain new experiences or information after the event occurs. This form of amnesia can be a result of various medical conditions, trauma, or psychological stress, but it is specifically related to the inability to create new long-term memories.

In contrast, retrograde amnesia involves a loss of memories that were formed before the onset of amnesia, affecting past experiences but allowing for future memory formation post-event. Dissociative Identity Disorder and Dissociative Fugue are distinct dissociative conditions that relate to identity fragmentation and bewilderment about one's identity respectively, rather than focusing on the capacity to form new memories. Therefore, anterograde amnesia specifically addresses the inability to form new memories after the onset of the condition, making it the correct answer.
