Anterograde v. Retrograde Amnesia

The difference between retrograde and anterograde amnesia lies in the types of memories affected:

• Retrograde Amnesia: This type of amnesia involves the loss of memories that were formed before the onset of the amnesia. Individuals may have difficulty recalling past events or information that was learned prior to the event that caused the amnesia.

• Anterograde Amnesia: In contrast, anterograde amnesia affects the ability to form new memories after the onset of the amnesia. Individuals with this condition have trouble remembering information or events that occur after the injury or incident that caused the amnesia, even though memories formed before the incident may remain intact.
