Is there a cure for diss-associative personality disorder? what medications are most commonly used and effective for this disease?

No cure: It's rare and controversial and as all personality disorders, w/out cure. Medications are used for symptom relief. Believed to often have roots in severe childhood abuse, best results are from extensive psychotherapy.
