Cerebral tumours presenting with psychiatric symptoms.

Four cases of cerebral tumours presenting with psychiatric symptoms were referred to the psychiatrist for management. They displayed some degree of cognitive impairment, notably impaired memory for recent events, and nominal aphasia. Clinical neurological examinations were generally unremarkable with no evidence of focal signs or features of raised intracranial pressure. CT scan demonstrated parietal lobe lesions in all four patients with two showing involvement of the frontal lobe, one the temporal lobe and another the occipital lobe as well. Only one patient was operated, two died and the last continued treatment elsewhere. Factors contributing to the psychiatric symptomatology of cerebral tumours are raised intracranial pressure, location of the tumour, nature of the tumour and the individual constitution and response of the patient.
