“It is unlikely that one ANP will serve as a constant throughout the person's life. Your client is, therefore, likely to have others besides the ones you know, or several who you might think of as "the host". Adults with dissociative disorders often have several ANPs from earlier stages of life inside. They usually have the same name but are of different ages. Sometimes, there are several current ANPs, each of whom assumes she or he is the "real" person and is amnesiac for the existence of the others. Their current knowledge and experience may overlap, while their other characteristics differ somewhat. This makes them glide easily from one to the other, and the therapist can easily miss the switch. p22”
