Women receive DID diagnoses at nine times the rate of men, with researchers believing that the disorder often stems from serious past abuse, notes MedicineNet.com. Trauma during an individual's formative years, at and around the age of six, such as the loss of a parent or sexual assault is particularly impactful, explains Medical Daily. Including borderline personality disorder and schizophrenia, over 9 percent of all American adults ultimately receive a dissociative disorder diagnosis at some point.
