INTRACRANIAL TUMORS WITH PSYCHIATRIC-DISORDERS AS THE 1ST MANIFESTATIONS

In addition to neurological deficits, headache, seizures, and intracranial hypertension, psychiatric disorders may occur as the first manifestation of intracranial tumor (13.6 % in the authors series). Seven cases with isolated or predominant psychiatric disorders at the time of diagnosis are reported. The pattern of psychiatric manifestations varied widely across patients and was not strongly related to the histological type or location of the tumor. An intracranial tumor should be looked for when isolated psychiatric disorders develop in the absence of a triggering factor in a patient with no history of psychiatric disease.
