[A Trial of Unified Management of Language Tasks Using a Tablet Device for Language Area Mapping].

Language tasks must be based on perioperative neuropsychological evaluation during intraoperative language area mapping for the resection of brain tumor near the language cortex under awake craniotomy. However, flexibility is needed during surgery, because actions during surgery must change based on neurological symptoms and the presence or absence of aphasia. Here, we developed software to assess patients' ability to complete language tasks during surgery by using a tablet device; these language tasks serve as indicators of changes in patient status. We examined its effectiveness through the use of the software. In this case, the patient was a 68-year-old female. Before the surgery, the patient exhibited transcortical sensory aphasia. However, 1 day before the surgery, she exhibited worsening of language symptoms. We prepared a language task on the tablet device based on the patient's ability to complete the task before the surgery. The patient's wakefulness baseline was different from that predicted before the surgery. However, we were able to modify the surgical plan by using the results of the language task on the tablet device. In addition, we were able to finish mapping in approximately 90 minutes.
