Objective To assess standard of care neuropsychology testing across multiple level IV epilepsy centers

Background

Laser interstitial thermal therapy (LITT) is a minimally invasive epilepsy surgery option with increasing evidence regarding efficacy outcomes for seizure freedom and cognition. While post operative neuropsychology outcomes are long published for open resection, data are less available for LITT. The standard of care LAANTERN (Laser Ablation of Abnormal Neurological Tissue Using NeuroBlate System) Registry is an ongoing prospective multi-center study of LITT patients which did not include neuropsychological outcomes. Standard of care multicenter neuropsychology testing collection is complicated by differing testing protocols between centers.

Design/Methods Active epilepsy LITT sites within LAANTERN were identified. An electronic survey instrument that interrogated standard of care neuropsychological measures and timing of administration at each site was distributed to 17 LAANTERN sites.

Results Ten respondents (60% neuropsychologist, 20% epileptologist/neurologist, 20% epilepsy surgeon) at nine sites completed the survey instrument. All ten respondents regularly assess each cognitive domain. All sites perform comprehensive neuropsychology testing pre-LITT; however, no single neuropsychology test is performed across all centers. The Boston Naming, Digit Span, Grooved Pegboard, Trail Making Test A&B, and Wechler’s Memory Scale were done by nine of ten respondents. Two thirds of tests are done by >50% of respondents. Most (90%) repeat neuropsychology testing between six to 12 months following surgery.

Conclusions All responding LAANTERN sites perform comprehensive preoperative neuropsychological testing. Neuropsychological test selection ranges greatly between centers which can impact multicenter study design. Based on survey results, seven tests can be considered “preferred”, which include the above-mentioned tests as well as the Brief Visuospatial Memory Test-Revised and the Animal Naming Test. A multicenter study (NCT05075850) was initiated from these results to explore potential changes across cognitive domains and raw scores after LITT.
