unfortunately it does, and it is often misdiagnosed for many other illnesses before it is diagnosed correctly. the best thing to do is to screen professional before you go see them. both my psychiatrist and phd questions dissociative disorder but neither knew enough about it so just stuck with bipolar and ptsd which i have but despite three years of treatment i just got worse. i then found a trauma t that specialized in dissociation and things got much better. she diagnosed me right away. finding the right person that specializes is the key. good luck.
