What is the term for an inability to remember parts of a traumatic event?

The term for an inability to remember parts of a traumatic event is dissociative amnesia. This condition specifically refers to a type of memory loss that is triggered by traumatic or stressful experiences, resulting in the individual being unable to recall important personal information related to those events. This form of amnesia is often observed in individuals who have experienced psychological trauma, leading to a disconnect from the memories associated with the distressing experience.

Dissociative amnesia is different from general memory loss, which does not necessarily pertain to trauma or is not classified as a dissociative disorder. Post-traumatic amnesia generally refers to a period of confusion and disorientation following a head injury, rather than a memory loss related to emotional or psychological trauma. Repressed memory is a broader concept that involves the unconscious blocking of memories of traumatic events but does not specifically highlight the inability to recall parts of an event as seen in dissociative amnesia.
