My mother had this and I'm aware of the reasons for fracturing into the various identities. I also have been diagnosed with the disorder by my psychologist , and am under medication from my psychiatrist. I also have physical brain damage from being hit as a pedestrian and landing on my head, and was treated by a neuropsychological doctor and rehabilitation clinic. I also know the various reasons
for my fracturing. I want to know if there is also a gene that was inherited. Another fact: I have leukaemia ,received extreme chemo for two years 1992-1993 and was cared for by Hospice, but somehow recovered.
