Main points of disagreements are:

1.  Whether MPD is a real disorder, or just a trend.

2. If it is real, is the appearance of multiple personalities real or delusional?

3. Whether it can be cured and should be cured.

4.  Whether it is invariably a disorder or simply a way of being.

5. Whether should define the experience or those who believe that they are “multiple” identities or personalities.

6. Whether it is based on contact with the outside world.
