Amnesia
refers to the loss of memories, such as facts, information and experiences. Though forgetting your identity is a common plot device in movies and television, that's not generally the case in real-life amnesia.
Instead, people with amnesia ( also called amnestic syndrome ) usually know who they are. But, they may have trouble learning new information and forming new memories.
