[Chronic schizophreniform psychosis in primary hyperparathyroidism].

We delineate the case history of a 74-year-old female patient. On the occasion of acute physically established psychoses in this case, we were able to detect a primary hyperparathyroidism due to adenoids of the epithelial body. This critical psychopathological condition developed from a psychosyndrome, most likely seeming as senile schizophrenia, and which had previously existed for four years. It will be discussed whether these chronic schizophrenia-like symptoms and signs can be explained by hyperparathyroidism.
