Stephen was recently involved in a car accident in which he was critically injured. He is unable to recall the events that led to the accident. Stephen is suffering from ________.

A) anterograde amnesia
B) retrograde amnesia
C) dissociative amnesia
D) infantile amnesia

Retrograde amnesia is a condition where an individual is unable to remember events that occurred before the onset of amnesia, such as Stephen’s inability to recall the events leading to the car accident. Anterograde amnesia is a condition where an individual is unable to form new memories after the onset of amnesia. Dissociative amnesia is a condition where an individual is unable to recall important personal information, usually due to a traumatic or stressful event, but it is not related to brain injury or disease. Infantile amnesia is a normal developmental process where individuals cannot remember events that occurred during infancy and early childhood.
