We evaluated the feasibility of the Bonn Leistungs Tracking Test (BLTT), a time-efficient screening tool assessing episodic memory, semantic memory, and executive functions in patients with high-grade temporal lobe gliomas. Methods: Twenty patients undergoing resection of temporal high-grade glioma between 2019 and 2022 underwent preoperative cognitive assessment using either the BLTT or a comprehensive neuropsychological battery routinely applied in temporal lobe epilepsy surgery. Results: Twelve patients (60%) underwent the BLTT, and eight (40%) underwent the standard neuropsychological test battery. The BLTT was feasible in all 12 individuals (0% drop-out), whereas only four of eight patients (50% drop-out) were able to complete the standard battery. The mean BLTT total score was 69.3 (SD 4.5), indicating impaired neurocognitive performance relative to normative data. The BLTT provided evaluable domain-specific measures across episodic memory, semantic memory, and executive functioning despite the high discontinuation rate observed with standard testing. Conclusions: The BLTT showed high feasibility for preoperative neurocognitive testing in patients with temporal high-grade gliomas. Its brief administration time and consistent applicability across relevant cognitive domains support its utility for routine neurocognitive assessment.<\/jats:p>","DOI":"10.3390\/neurosci7040091","type":"journal-article","created":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T09:30:53Z","timestamp":1787131853000},"page":"91","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The BLTT (Bonn Leistungs Tracking Test) in Patients with Temporal Lobe Gliomas\u2014Feasibility of a Novel Neurocognitive Test Battery"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-4987-4946","authenticated-orcid":false,"given":"Sarah-Marie","family":"Gallert","sequence":"first","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"},{"name":"Tumor Translational Research Group, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3593-8192","authenticated-orcid":false,"given":"Julia","family":"Taube","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Epileptology, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5710-6557","authenticated-orcid":false,"given":"Anna-Laura","family":"Potthoff","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"},{"name":"Tumor Translational Research Group, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-2919-8622","authenticated-orcid":false,"given":"Thomas","family":"Zeyen","sequence":"additional","affiliation":[{"name":"Clinic for Neuro-Oncology, Center for Neurology and Integrated Oncology (CIO), University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5905-4121","authenticated-orcid":false,"given":"Valeri","family":"Borger","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4828-7496","authenticated-orcid":false,"given":"Motaz","family":"Hamed","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3177-8582","authenticated-orcid":false,"given":"Rainer","family":"Surges","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Epileptology, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hartmut","family":"Vatter","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Helmstaedter","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Epileptology, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6025-7479","authenticated-orcid":false,"given":"Matthias","family":"Schneider","sequence":"additional","affiliation":[{"name":"Clinic and Polyclinic for Neurosurgery, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"},{"name":"Tumor Translational Research Group, University Hospital Bonn, University of Bonn, 53127 Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"574","DOI":"10.1001\/jama.2023.0023","article-title":"Glioblastoma and Other Primary Brain Malignancies in Adults: A Review","volume":"329","author":"Schaff","year":"2023","journal-title":"JAMA"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"323","DOI":"10.1007\/s11060-016-2114-0","article-title":"Neurocognitive Functioning in Patients with Glioma of the Left and Right Temporal Lobes","volume":"128","author":"Noll","year":"2016","journal-title":"J.
