One model holds that verbal delayed recall is hippocampal dependent, whereas verbal paired associate learning relies on adjacent rhinal cortex. We test this by examining the relationship between task performance and regional temporal lobe volumes in individuals with temporal lobe epilepsy and hippocampal sclerosis (TLE\u2010HS).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Retrospective analysis of 99 surgically na\u00efve TLE patients (12 bilateral TLE\u2010HS, 35 left TLE\u2010HS, 28 right TLE\u2010HS, and 24 MRI\u2010negative left TLE) with contemporaneous neuropsychological and T1\u2010weighted MRI data. Delayed recall was operationalized using the Rey Auditory Verbal Learning Test, and arbitrary associative learning with the Paired Associates Learning subtest. Linear regressions assessed associations between memory performance and temporal lobe volumes. We also studied a cohort with nonlesional left TLE to better distinguish the relative impact on verbal memory of left temporal onset seizures versus the structural integrity of the left mesial temporal lobe.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Patients with left\u2010sided TLE\u2010HS (unilateral\/bilateral) performed significantly worse on both memory measures compared to right TLE\u2010HS and MRI\u2010negative left TLE (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).

Associations with the temporal pole and inferior temporal regions suggest additional contributions from extrahippocampal areas. Left hippocampal atrophy exacerbates verbal memory impairment beyond what would be expected from seizure activity alone.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Plain Language Statement<\/jats:title>\n                    <jats:p>The results of this study show that the ability to learn semantically unrelated information and recall unstructured information after a period of delay is particularly compromised in individuals with left hippocampal atrophy. These impairments were strongly associated with reduced left hippocampal volume. In contrast, volumes of the adjacent rhinal cortex were not related to memory performance. These findings underscore the central role of the left hippocampus in supporting verbal memory in temporal lobe epilepsy.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/epi4.70195","type":"journal-article","created":{"date-parts":[[2026,3,26]],"date-time":"2026-03-26T09:33:17Z","timestamp":1774517597000},"page":"764-776","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluating the task\u2010specificity model of verbal memory: Regional volumetric analyses in temporal lobe epilepsy with hippocampal sclerosis"],"prefix":"10.1002","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0484-2830","authenticated-orcid":false,"given":"Andy","family":"Sitoh","sequence":"first","affiliation":[{"name":"School of Psychological Sciences University of Melbourne  Melbourne Victoria Australia"},{"name":"Department of Clinical Neuropsychology Austin Health  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Weintrob","sequence":"additional","affiliation":[{"name":"Department of Clinical Neuropsychology Austin Health  Melbourne Victoria Australia"},{"name":"Bladin\u2010Berkovic Comprehensive Epilepsy Program, Department of Neurology Austin Health  Melbourne Victoria Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacqueline F.
