The problem with your analysis is that the evidence indicates that Cayce guided the doctors, not the other way around. For example, Cayce's most famous early cure was of Aime Dietrich, the daughter of Professor Charles Dietrich, the first commissioned officer to graduate from Ohio State University's military program and the former superintendent of schools of Hopkinsville, Ky. According to Professor Dietrich's October 8, 1910 affidavit, filed in Hamilton County, Ohio:
"March 1st, 1902, she [Aime] was taken to Dr. Hoppe of Cincinnati, O., who made a most thorough examination. He pronounced her a perfect specimen physically, except for the brain affection, concerning which he state that only nine cases of this peculiar type were reported in Medical Records, and every one of these had proved fatal. He told us that nothing could be done, except to give her good care, as her case was hopeless and she would die soon in one of these [epileptic] attacks.
"At this period our attention was called to Mr. Edgar Cayce, who was asked to diagnose the case. By auto-suggestion, he went into a sleep or trance and diagnosed her case as one of congestion at base of the brain, stating also minor details. He outlined to Dr. A. C. Layne [Al C. Layne, D.O.], now of Griffin, Ga., how to proceed to cure her. Dr. Layne treated her accordingly, every day for three weeks, using Mr. Cayce occasionally to follow up the treatment, as results developed. Her mind began to clear up about the eighth day and within three months she was in perfect health, and is so to this day. This case can be verified by many of the best citizens of Hopkinsville, Ky."
