RESUMO
BACKGROUND: Brain tumor location is related with specific, focal neurological impairment, but also with more diffuse, generalized and subtitle neurocognitive dysfunctions. For a better evaluation of these cases, we need a specific battery of tests. Beside the impact of preoperative status on surgical decision, the quantification of postoperative function alteration is essential in neurorehabilitation. PATIENTS, MATERIALS AND METHODS: We proposed a battery of tests to assess the neurocognitive function, with an accent on language adapted to Romanian population. The 43 cases included in the study were tested preoperatively, seven days postoperatively and at one month, and correlated with the images and histological results. RESULTS: At admission, from all participants, 11.6% were affected across all measured items and 6.9% on none of them. A rate of impairment significantly higher, four or more items, was observed in glioblastoma (GB) cases (23.3%) in contrast with low-grade glioma (LGG) (0%), meningioma (0%) and metastases (6.9%). From all cases, we performed seven awake craniotomies. At one-month evaluation, general decrease in neurocognitive function was observed in 20.93% cases, among them 88.88% being GB and favorable outcome in 32.55% patients with dominance of LGG and meningioma cases. CONCLUSIONS: A neurocognitive assessment of brain tumor patients is important for preoperative and postoperative evaluation and secondary adjustment of the surgical resection in order to improve or, at list, meantime the initial status. The role and the link between the histological type and tests alteration were observed. The results can be used for a better understanding and management of language area tumors.
