In June 1970, Michel had a third
seizure at the psychiatric hospital where she had been staying. She was prescribed anti-convulsion drugs for the first time, including
Dilantin, which did not alleviate the problem. She described seeing "devil faces" at various times of the day. Michel's treatment in a psychiatric hospital did not improve her health and her depression worsened. Long-term treatment did not help, either, and she grew increasingly frustrated with her medical care after having taken pharmacological drugs for five years. Her escort in Piacenza was convinced that she was suffering from demonic possession because she was unable to walk past a crucifix and refused to drink the water of a Christian
holy spring. Michel believed she could communicate with
Mary, mother of Jesus. Michel's family and community became convinced that she was possessed and consulted several priests to request an
exorcism. The priests declined, recommended the continuation of medical treatment and informed the family that exorcisms required the bishop's permission. In the
Catholic Church, official approval for an exorcism is granted when the subject strictly meets the set criteria and is considered to be suffering from possession () and under demonic control. Intense dislike for religious objects and supernatural powers are some of the first indications. Michel worsened physically and displayed aggression, injured herself, drank her own urine and ate insects. In November 1973, Michel began treatment with
Tegretol, an anti-seizure drug and
mood stabilizer. She was prescribed
antipsychotic drugs during the course of the religious rites and consumed them frequently until some time before her death. Despite taking these
neuroleptic medications, Michel's symptoms worsened and she began "growling obscenities, screaming guttural curses, and raving wildly." ==Exorcism==
