Iatrogenic disease or doctor-patient collusion?

"Iatrogenic disease" may be a misnomer and would be better termed "syndyadogenic disease"--literally, a disease caused by two people working together. Most iatrogenic disease is a result of an unconscious coequal collusion between doctor and patient. Using the psychoanalytic concepts of transference and countertransference, three patterns of doctor-patient collusion are seen: the needy child-omnipotent parent posture, the Pollyanna posture and the persecutor-victim posture.
