Regional brain function in hallucinations: a study of regional cerebral blood flow with 99m-Tc-HMPAO-SPECT in patients with auditory hallucinations, tactile hallucinations, and normal controls.

From the supposition that there exists a possible connection between certain psychopathological symptoms, and/or syndromes (e.g., hallucinations) and regional cerebral dysfunction, patients suffering from auditory and tactile hallucinations were investigated, in a symptom-oriented study, using the method of technetium-99m-Hexamethyl-propylenamine Oxime (99m-Tc-HMPAO)-Single Photon Emission Computed Tomography (SPECT) and compared with normal controls. The results support Jackson's hypothesis to the effect that hallucinatory phenomena will primarily occur when the normally inhibitive influence of the upper cortical centers over the lower brain structures diminishes, resulting in relative hyperactivity in the basal regions. In addition to the brain activity-changes generally observed in hallucinating patients, it was possible to identify regional cerebral blood flow (rCBF)-distribution patterns characteristic in certain forms of hallucinatory phenomena, i.e., a significant increase of activity in the hippocampal regions (including hippocampus, parahippocampus, and amygdala) only in patients with auditory hallucinations, and a significant reduction of rCBF in the inferior temporal regions in patients with tactile hallucinations.

Capgras syndrome and functional psychosis in 2 survivors of torture.

Functional psychosis has only rarely been described in context with extreme stressors, most studies focusing singularly on posttraumatic stress disorder symptoms. We report for the first time the case histories of 2 patients suffering from Capgras syndrome along with schizoaffective disorder and posttraumatic stress disorder after prior experience of prolonged torture. Interaction of personal life experience and psychiatric disorder are proposed as factors resulting in persistent changes in perception and affect.

Comparison of delusions among schizophrenics in Austria and in Pakistan.

One of the central purposes of cross-cultural psychiatry is to scrutinize the sociocultural influences on the phenomenology of psychiatric diseases. On the other hand it is possible to lay bare a nucleus of symptoms, common to all cultures, which, independently of all influences, occupies a central position for an understanding of the disease considered. In this study an attempt was made to approach this problem by means of investigating the contents of delusion of schizophrenic patients in Austria and Pakistan. The contents of delusion among 126 Austrian and 108 Pakistani patients diagnosed as having schizophrenia according to DSM-III-R (art. 295) were compared following the classification of Huber and Gross. Additionally the kind of persecution and the type of the persecutor were registered. However it appeared that only a few contents of delusion are frequent in both countries. In both countries persecution was the most frequently mentioned content of delusion. The comparison of the contents of delusion revealed significantly higher frequencies of delusions of grandeur, guilt and religious delusions in Austrian patients. Significant differences could also be found with the kind of persecution and the persecutor's type. Cultural factors seem to have a decisive influence on shaping the contents of delusion.
