The incidence and prevalence of mental diseases are growing throughout the world and their causes are not yet clearly established in spite of the recent advances in modern psychiatry. By using mediumnistic techniques, or the human ability to enter spiritual reality in an objective manner, we have come into contact with spirits and spiritual contexts that have a well defined relationship with each patient. This has happened in healing sessions in Spiritist Centers for patients with different mental diseases, such as depression, autism, schizophrenia and panic disorder.

The diagnostic approach to uncover the spiritual aspects of each case happened with the aid of a team of doctors-mediums. In all cases the spirits were of human beings who had lived their lives in the past such as we live ours in the present. They were now in a spiritual reality that is a world parallel to ours. They interfered psychically in the lives of the patients, causing harm and maintaining the symptoms of specific mental diseases.

The ties between these spirits and the patients were established in previous lives and old reincarnations. In a non-controlled prospective study of 48 patients with the mental diseases mentioned above, we were able to perceive them and to act in a psychotherapeutic manner with them such that we were able to undo the spiritual ties of each case. This resulted in an evident improvement of a significant percentage of the cases and even resulted in the complete and sustained recovery of many of them.
