Does the Diagnosis of Depression in Head and Neck Cancer Mask Organic Brain Disease?

Scant attention has been paid to emotional changes as possible symptoms of impaired cerebral functioning in cancer patients. A retrospective study was conducted to determine the variety of organic brain syndromes (OBS) that presented with depressive symptoms in 20 head and neck cancer patients. The impressions of referring surgeons were in error in 16 patients (80%). Twelve (60%) had unsuspected OBS, with treatment resulting in reversal of symptoms in almost half. Of the eight patients with functional disorders, four received a final diagnosis of depression. Head and neck surgeons should be aware that (1) emotional changes in their patients frequently reflect OBS, some potentially reversible, (2) because of the ages of the patients, senile dementia may be a more common occurrence in head and neck cancer than suspected, and (3) because of the difficulties of evaluating changes in higher mental functions, more neuropsychiatric consultations may be warranted for head and neck patients.
