Measuring clinical outcomes in neuro-oncology. A battery to evaluate low-grade gliomas (LGG).

We describe how a neuropsychological evaluation in patients with brain tumors should be performed, specifically in the case of low-grade gliomas. Neuropsychological examination is crucial before starting any treatment as well as during the follow-up, since it can improve neurosurgery techniques and reveal potential cognitive effects of chemotherapy and radiotherapy, besides planning rehabilitation. We underline that sensitive and wide-ranging tests are required; specific tasks based on the lesion site should be added. Moreover, some tests can provide additional information about the evolution of the tumor. A careful, thorough examination improves quality of life.
