Question

Quizplus · Accepted Answer

Retrograde amnesia is the loss of memory for events that occurred before an injury or traumatic event. T.J's inability to remember the accident and events leading up to it suggest retrograde amnesia. Anterograde amnesia, on the other hand, pertains to the inability to form new memories after an injury or traumatic event. Alzheimer's disease is a degenerative brain disorder characterized by progressive memory loss and cognitive decline, whereas infantile amnesia pertains to the lack of memories from early childhood.
