Though little evidence exists in regard to the relationship to genetics and the development of the disorder, Yoichiro O. Fuji developed a hypothesis that family history may play a critical role in our understanding of the development dissociative identity disorder. Fuji compared the numbers of diagnosed cases in North America and India to the differences in Japan and found fair evidence in a link between hereditary factors to the disorder. In researching the background of each subject, the analysis of any prior schizophrenia or child abuse symptoms were evaluated. The study found that a very detailed record of life history beginning from infancy was gathered, which reflected diagnostic interaction with each patient and the family. With the emergence of DNA testing and advancement of medicine and science, evidence was supported to the findings that genetic mutations that are passed down from parent to child. (Fuji, 1998). In an article by Dr. Catherine Hayes titled Multiple Personality Disorder: an introduction for HCAs, Hayes states “…that there is a genetic predisposition to developing the condition, which certain environmental triggers then initiate (Bassett et al, 2010; Clarke et al, 2009 as cited in Hayes, 2014) It was also found that the condition was found to be present in late adolescence/early adult hood and impacted both men …show more content…
Childhood trauma, post-traumatic stress disorder (re-visited from the nurture perspective), increase in prevalence ratings, media influence and the sociocognitive theory provides a basis for this debate.
Childhood trauma is considered the number one factor in the likely causes of the development of dissociative identity disorder. It is believed that when a child suffers a traumatic event, such as sexual abuse or neglect, the child then copes with the experience by creating a different ‘identity’. Craig M. Traub accounts a theory that children whom experience trauma often dissociate or compartmentalize their distressing experiences and repress these memories. Dissociation and repression prevent the overwhelming intra-psychic distress by preventing traumatic memories from entering into the conscious awareness. (Ludwig, 1983 as cited in Traub, 2009) In order to validate childhood trauma as an etiology for the development of dissociative identity disorder, the abuse must be verified but has been found to be extremely difficult to do
