Language testing in brain tumor patients.

Neuropsychological testing is not a luxury in the management of patients with brain tumors. Regardless of the therapeutic approach selected in each case (but, especially in the case of awake surgery), it provides information on the status of language and other cognitive functions. This information can be used preoperatively to identify eloquent areas and to provide a baseline against which further examinations can be evaluated, intraoperatively to identify eloquent areas, and post-operatively and at follow-up to ascertain the short-term and long-term consequences of surgery, as well as those of other treatments (chemotherapy and radiotherapy), and to plan and monitor rehabilitative treatments.
