What Is Amnesia?
Amnesia is a condition involving partial or complete memory loss that affects a person’s ability to remember past events, form new memories, or both. It can develop suddenly after an injury or illness or gradually as part of certain neurological disorders. Amnesia affects memory but does not usually change intelligence, personality, or general awareness.
The severity and duration of amnesia vary depending on its underlying cause.
