Define and describe three dissociative disorders. Explain how these disorders differ from one another.

The three dissociative disorders are $\textbf{dissociative amnesia}$, $\textbf{dissociative fugue}$ and $\textbf{dissociative identity disorder}$.

$\textbf{Dissociative amnesia}$ is an inability to remember certain information and it is usually caused by traumatic experience. It is important to differentiate this type of amnesia from other types with different causes.

$\textbf{Dissociative fugue}$, also called traveling amnesia, is amnesia plus escape to a different location away from home. There is no way of knowing how long will the amnesia last so a person may start a new life in a new location without remembering anything from the life before.

Finally, $\textbf{dissociative identity disorder}$ can be described as multiple personalities in one person or a fragmented personality. Each personality can take over at a different time.

All of the three disorders are a way of escaping from something the people who suffer from them cannot deal with. The difference between them is that in dissociative amnesia the persons forget certain information, events, but they remain themselves. In dissociative fugue a person may create the entirely new identity while in dissociative personality disorder a person keeps his or hers personality but it is not their only identity.
