Amnesia

The leading causes of amnesia健忘症 are either physical or psychological.

In antergrade amnesia, the subject is unable to recall the events that occur after a shock or an injury to the brain; however, past memories will not be lost.

In retrograde amnesia, the patient is capable of recalling events that occur after the trauma; interestingly enough, the information stored before the shock, is lost and cannot be retrieved.

In paraamnesia, established memories are contorted. In psychogenic fugue, the subject may venture into a new lifestyle, trying to repress memories which lead to trepidation. The events happening during psychogenic fugue are non-retrievable. Nonetheless, the experiences that happened before the onset can be recovered.
