In the movies, people with amnesia forget who they are. Isn that a memory disorder?
This kind of memory loss is often called a “fugue state”. People who enter fugue state may completely forget their identities and personal histories. Fugue state is usually the result of psychological trauma (for example, witnessing a violent crime) and often resolves itself with time or with psychotherapy. Thus, it is a different kind of syndrome from memory disorders such as anterograde amnesia, which typically result from brain injury and which are typically permanent conditions.
