1. The leading causes of amnesia are either physical or psychological. In
2. antergrade amnesia, the subject is unable to recall the events that occur after
3. a shock or an injury to the brain; however, past memories will not be lost. In
4. retrograde amnesia, the patient is capable of recalling events that occur after the
5. trauma; interestingly enough, the information stored before the shock, is lost
6. and cannot be retrieved. In paraamnesia, established memories are contorted.
7. In psychogenic fugue, the subject may venture into a new lifestyle, trying to
8. repress memories which lead to trepidation. The events happening during
9. psychogenic fugue are non-retrievable. Nonetheless, the experiences that
10. happened before the onset can be recovered. Among the most popular
11. treatments for psychologically related amnesia are psychotherapy, the use of
12. drugs, and hypnosis.
