Abstract:
Verst-Maldaun Language Assessment (VMLA) is a new intraoperative neuropsychological test (NT) within our local culture, e.g., native Portuguese speaking Brazilians. It aims to fill the specific need of an objective and dynamic approach for assessing the language network during awake craniotomies. The test includes object naming (ON) and semantic functions. This paper describes the process of validation, allowing for other centers to create their own language assessment. The validation process included 248 volunteers and the results were associated with age, gender and educational level (EL). The factor with the greatest impact was EL, followed by age. Intraoperative image learning by repetition is unlikely, since it is composed of 388 items and 70 combinations. The test will be available for free use under http://www.vemotests.com/ (beginning in February 2021).
