What are the symtops of multiple personality disorder?

DID: Currently called dissociative identity disorder (did), psychiatrists and clinical psychologists can diagnose this condition. However it often takes time to clarify the diagnosis. At first, the condition may present as a memory problem and extreme mood changes.

2 or more identities: Aka dissociative identity disorder, multiple personality disorder is characterized by 2 or more distinct identities or personality states "taking control" of a person’s behavior and by an inability to recall important personal information that isn't explained by forgetfulness. Each personality has its own pattern of perceiving, relating to, and thinking about the environment and self.

Multiple personality: MPD, now called dissociative identity disorder is characterized by two or more distinct identity states known as alters in addition to the patient him/her self. These identity states will seem fragmentary and partially unaware of the others, each with varying degrees of disturbance, The alters tend to be more active and aggressive, while the patient's core personality will be more passive.
