Answer:
Retrograde amnesia, anterograde amnesia
Explanation:
Retrograde amnesia: This type of amnesia occurs when a person is not able to remember memories or events. An individual is not able to recall past events, especially episodic events. On the other hand, anterograde amnesia occurs when a person is not able to create new memories. Amnesia is defined as the sudden loss of the memory in which a person loses the memory of what happened before the amnesia and what is currently going on in the life of a person. Retrograde amnesia is the failure to retrieve memory and anterograde amnesia is a failure to store memory.
