Question

which is an example of retrograde amnesia?
an individual remembers their adult children, but cannot create new memories.
an individual cannot remember their wedding, which occurred 20 years ago and cannot learn new things.
an individual cannot remember who they are after a traumatic accident.
an individual is able to learn new things, but is unable to remember who their adult children are.

Explanation:

Retrograde amnesia is defined as the inability to recall memories formed before the onset of amnesia, while the ability to form new memories remains intact. Let's analyze each option:

1. The first option describes anterograde amnesia (cannot create new memories, retains old ones).
2. The second option combines both retrograde and anterograde amnesia (loses old memories and can't form new ones).
3. The third option describes a more severe global amnesia or identity loss, not specific retrograde amnesia.
4. The fourth option correctly fits: the person can learn new things (preserved anterograde memory) but cannot recall existing old memories (their adult children, formed before the amnesia onset).

Answer:

D. An individual is able to learn new things, but is unable to remember who their adult children are.
