Abstract
Purpose: Patients with localized refractory temporal lobe epilepsy (TLE) enrolled in the presurgical workout protocol at Ghent University Hospital undergo, among many investigations, extensive neuropsychological assessment including auditory and visual naming tests. We developed dutch adaptations of these tests to presurgically asses visual object naming and auditory description naming in surgical candidates with lateralized refractory TLE. Both tests will eventually be adapted to be incorporated in the presurgical neurostimulation mapping protocol. Method: Auditory and visual naming target words were matched controlling for word frequency and word length, resulting in two equally difficult naming tasks. Stimuli were based on Snodgrass and Vanderwart pictures and dictionary definitions. Both naming tasks were administered to left and right lateralized TLE patients and the performance of both groups in both tasks was compared. Results: Patients with left lateralized focal TLE performed significantly worse on the auditory version of the naming task compared to the visual alternative. This pattern was also seen in the right lateralized group, but less pronounced. Also, the left lateralized group performed worse on the auditory naming test compared to the right lateralized group, while their results on the visual naming task were less differentiated. Conclusion: The inclusion of auditory and visual naming tasks in presurgical neuropsychological assessment of refractory epilepsy patients is a valuable tool in the prediction of possible naming decline after surgical intervention. Particularly, the inclusion of an auditory naming task proves to be a valuable addition because of its unique capability to capture subtle naming deficits in patients with left TLE. Auditory naming characterizes and lateralizes left TLE-associated language dysfunction better, compared to the visual alternative.
