Dissociative amnesia: Dissociative amnesia is a psychological disorder characterized by sudden and extensive memory gaps typically related to traumatic events.
Traumatic brain injury (TBI): TBI refers to any damage caused by an external force applied to the head, resulting in cognitive impairments including memory problems.
