Cerebral malignancy in psychiatry: EEG aspects

The prevalence of cerebral malignancy in psychiatric patients is investigated in our own clinical material and compared with literature data. The importance of cellular type and localization of the lesion is checked and related to clinical symptoms such as seizures and psychopathological symptoms. The recognition of cerebral malignancy in psychiatric patients, especially in the early stages when few or no neurological signs are present, is shown to be a complex clinical problem. The possibilities and restrictions of technical investigations in general and of the EEG in particular are stressed.
