Which characterizes Dissociative Amnesia?

Dissociative Amnesia is primarily characterized by the inability to recall important personal information, often associated with traumatic or stressful events. This condition is not simply forgetfulness but rather a type of memory loss that is often linked to psychological factors, allowing individuals to dissociate from emotional memories that may be distressing or overwhelming.

The significant lapses in memory can affect various aspects of a person’s life, leading to gaps in memory for specific events or even personal identity information. This aligns with the core nature of Dissociative Amnesia, where the person's conscious memory is disrupted, often as a coping mechanism.

The other options include elements that may relate to different psychological conditions. Inability to recall traumatic events is a component of amnesia but is broader and not exclusive to dissociative amnesia. Involuntary movements are more characteristic of movement disorders, while heightened alertness in stressful situations typically pertains to anxiety conditions, rather than amnesia. Thus, the essence of Dissociative Amnesia is best captured by the lapses of significant personal information.
