Abstract
We have experienced two cases admitted to a mental hospital in a prolonged condition of schizophrenia. They experienced morbid images like transient disturbances of consciousnesses, such as disorientation, amnesia and incoherence. After recovery from these symptoms, they experienced other images that suggested an organic defect. From the findings, it was presumed that increasing the dose of antipsychotic drugs leads to exacerbation of the symp-toms, and decrease or discontinuance of antipsychotics or treatment with agents for improving cerebral metabolism and circulation is effective. W e concluded that organic lesion may not always be caught macroscopically, and the presence of multiple infarctions as well as arteriosclerosis and minimal infarction occurring in early stages must not be ignored.
