Kriss Erickson is a victim of DID, but seems to lead a normal life….
“I do freelance writing and artwork and sing original songs in local coffee shops and outdoor fairs. I do excellent work but have a very hard time promoting myself. I’m fortunate to have been married to my husband for almost twenty-three years now. He has provided me a stable life, a nice home and a wonderful yard where I can commune with nature.”
Every alter knows to some degree what each alter and the host personality are doing or thinking.
Orbitofrontal Cortex
Neuroimaging studies has identified this area of the brain,
The Orbitofrontal Cortex
in particular, functions differently in DID patients.
Interesting fact: People began to take notice of dissociative identity disorder when the movie, "Three Faces Of Eve" was a major motion film. It sparked an interest and curiosity to both the common people and doctors.
Their Brain
MOST EXTREME kind of dissociation

Different identities, alters, may exhibit differences in:
speech, mannerisms, attitudes, thoughts, and gender orientation, etc.
"physical" properties
allergies, right-or-left handedness, etc.

Usually one of the sub-personalities – called the primary, or host, personality – appears more often than the others
A Multiple Presents HER view of DID: "We do not SUFFER FROM MPD. We SURVIVE because of MPD."
In a study, the brain's supply of blood flow in patients diagnosed with DID was decreased in the Orbitofrontal Cortex regions bilaterally,
which could explain why the patients have a lack of normal behavior.
The Orbitofrontal Cortex is involved with drive and with compulsive repetitive behaviors.
Mary was a quiet 30-year-old woman who was meek and reticent and had many avoidant traits. She was talking about some of the events of her past, which included severe sexual abuse starting at the age of 20 months. She began to tell the psychiatrist about a crying voice she heard constantly:
Mary: Baby cries all the time—Baby—I hear her. She is sad all the time. She can’t talk, but she cries all the time. (Mary stops speaking. Her demeanor and posture were now so different the psychiatrist was startled. It really felt as though a different person was in the room.)
Psychiatrist: Who? Baby?Mary (now Edith): Mary. She’s a wimp.Psychiatrist: What about Baby?Mary (now Edith): What are you talking about?Psychiatrist: May I speak to Mary?Mary (now Edith): She doesn’t have the guts to come here.
Mary (now Edith): She is a wimp. I would never put up with any of that sh--. I’ll kill him. I’ll kill him. I’ll kill you too and she deserves to die.
