Final answer:

Retrograde amnesia affects memory of events before a specific time, demonstrated by real cases like Scott Bolzan. Anterograde amnesia, seen in patients like H. M., hinders the creation of new memories. Demarcus's amnesia is retrograde due to his inability to recall events before his lacrosse match.


Explanation:

Retrograde amnesia is a memory disorder where a person is unable to recall events that happened before a specific time, often due to a trauma like a concussion. This is exemplified by cases like former NFL player Scott Bolzan who lost memory of years of his life instantly due to a head injury.


On the other hand, anterograde amnesia is characterized by the inability to form new memories after a certain point of time, as depicted by patients like H. M. who couldn't create new declarative memories post his injury.


Thus, in Demarcus's case, his amnesia is retrograde because he can't remember events that occurred prior to his lacrosse match due to the concussion-induced memory loss.
