This experiment assesses the accuracy of a non-medically trained Spiritualist medium in her ability to identify a medically diagnosed disease. The case is also illustrative of the discovery of one earthbound attached spirit and one discarnate entity that uses energy for its own survival that is transmitted by a living human. The dynamic relationship between the disease and the discarnate entities is implied.

OBJECTIVE:Belief in demonic influence has repeatedly been described as a delusion in schizophrenic patients. The goal of this explorative study was to examine the frequency, as well as the psychodynamic and social functions of such beliefs in a sample of nondelusional patients.
The sample consisted of 343 psychiatric outpatients who described themselves as religious. In semistructured interviews they were asked to give their view of demonic causality of their illness.
A high prevalence of such beliefs was not only found in schizophrenic patients (56%) but also in the following groups of nondelusional patients: affective disorders (29%), anxiety disorders (48%), personality disorders (37%) and adjustment disorders (23%). Belief in demonic oppression tended to be associated with lower educational level and rural origin, and was significantly influenced by church affiliation.
Beliefs in possession or demonic influence are not confined to delusional disorders and should not be qualified as a mere delusion. Rather they have to be interpreted against the cultural and religious background which is shaping causal models of mental distress in the individual.
We studied the similarities and differences between Brazilian Spiritistic mediums and North American dissociative identity disorder (DID) patients. Twenty-four mediums selected among different Spiritistic organizations in São Paulo, Brazil, were interviewed using the Dissociative Disorder Interview Schedule, and their responses were compared with those of DID patients described in the literature. The results from Spiritistic mediums were similar to published data on DID patients only with respect to female prevalence and high frequency of Schneiderian first-rank symptoms. As compared with individuals with DID, the mediums differed in having better social adjustment, lower prevalence of mental disorders, lower use of mental health services, no use of antipsychotics, and lower prevalence of histories of physical or sexual childhood abuse, sleepwalking, secondary features of DID, and symptoms of borderline personality. Thus, mediumship differed from DID in having better mental health and social adjustment, and a different clinical profile.
