Naming outcomes of anterior temporal lobectomy in epilepsy patients: A systematic review of the literature

Ives-Deliperi V.L. ; Butler J.T. (2012)


Anterior temporal lobectomy (ATL) is the standard surgical treatment for medically intractable temporal lobe epilepsy (TLE). While seizure outcome is favorable, cognitive outcomes are a concern, particularly in respect of memory and naming. A systematic review of the literature on the naming outcomes of ATL is presented in this article. Searches were conducted on PubMed and PsycInfo, yielding a total of 93 articles, 21 of which met inclusion criteria. Declines in visual naming are common following ATL in the dominant hemisphere, and particularly, for naming living stimuli or famous faces. The Boston Naming Test (BNT) declines by a mean of 5.8 points, exceeding the Reliable Change Index (RCI). There are no reports of deficits in auditory naming following ATL, despite the fact that auditory naming has shown to be a more sensitive measure of dysnomia than the BNT in TLE patients. The absence of structural hippocampal pathology and late-onset epilepsy are the strongest predictors of naming decline. Recommendations are made for further study. © 2012 Elsevier Inc.
