Filling the gap: brief neuropsychological assessment protocol for glioma patients undergoing awake surgeries.

Introduction: The literature lacks a concise neurocognitive test for assessing primary cognitive domains in neuro-oncological patients. This study aims to describe and assess the feasibility of the Ohy-Maldaun Fast Track Cognitive Test (OMFTCT), used to pre- and post-operatively evaluate patients undergoing brain tumor surgery in language eloquent areas. The cognitive diagnosis was used to safely guide intraoperative language assessment.

Methodology for creating and validating object naming and semantic tests used by Verst-Maldaun Language Assessment during awake craniotomies.

Verst-Maldaun Language Assessment (VMLA) is a new intraoperative neuropsychological test (NT) within our local culture, e.g., native Portuguese speaking Brazilians.

Monopolar 250-500 Hz language mapping: Results of 41 patients.

Objectives: To determine whether high-frequency 250-500 Hz monopolar stimulation is effective for mapping cortical and subcortical language structures during brain tumor resection.

Methods: Using high-frequency monopolar stimulation, we mapped the speech areas of 41 awake patients undergoing brain tumor resection in the dominant hemisphere, subject to risk of lesions in the cortical and subcortical speech tracts. Patients were tested for object naming, semantic and other language tasks.

"Next Door" intraoperative magnetic resonance imaging for awake craniotomy: Preliminary experience and technical note.

Background: During glioma surgery "maximal safe resection" must be the main goal. Intraoperative magnetic resonance imaging (iMRI) associated with awake craniotomy (AC) is a valuable tool to achieve this objective. In this article, AC with a "next-door" iMRI concept is described in a stepwise protocol.
