Naming assessment is a core component of neuropsychological evaluation, particularly in the surgical work up for patients with pharmacologically refractory epilepsy. Specifically, naming deficits are typically associated with left, but not right hemisphere epilepsy, thereby assisting with lateralization of seizure onset. We sought to determine whether bilingual (English as second language, ESL) and monolingual epilepsy patients with comparable education, intelligence, and objective vocabulary performance would perform similarly on standard naming measures, and whether ESL patients would demonstrate laterality effects in naming, similar to that observed in monolingual patients.
Participants were 242 adults with epilepsy (186 native, 56 ESL) who underwent neuropsychological evaluation and obtained normal range or higher scores on the Wechsler Adult Intelligence Scale (R/III/IV) Vocabulary subtest (scaled score≥8). Groups were compared on demographic factors and language performances (i.e., Boston Naming Test, Auditory & Visual Naming Test, word reading, fluency).
Groups did not differ with respect to age, education, FSIQ, vocabulary, reading, or verbal fluency. However, ESL speakers earned poorer scores than native English speakers on all naming measures. Moreover, among ESL participants with unilateral epilepsy, a significant proportion of right hemisphere patients scored below cutoff for impairment. This contrasted with the more typical finding among native English speakers, whereby a significant proportion of left patients demonstrated naming impairment.
These results underscore the complexity of verbal assessment in bilinguals, suggesting that naming performances by ESL individuals, even those considered proficient, with strong performances on other English verbal measures, cannot be interpreted by the same standards applied for native speakers.

命名评估是神经心理学评估的核心组成部分，特别是在药物难治性癫痫患者的手术准备中。具体而言，命名缺陷通常与左半球癫痫相关，而与右半球癫痫无关，从而有助于确定癫痫发作的偏侧化。我们试图确定具有相似教育程度、智力和客观词汇表现的双语（英语作为第二语言，ESL）和单语癫痫患者是否会在标准命名测量中表现相似，以及 ESL 患者是否会表现出命名的偏侧化效应，类似于单语患者观察到的效应。
参与者为 242 名患有癫痫的成年人（186 名母语为英语，56 名 ESL），他们接受了神经心理学评估，并在韦氏成人智力测验（R/III/IV）词汇分量表上获得了正常范围或更高的分数（量表得分≥8）。对两组在人口统计学因素和语言表现（即波士顿命名测验、听觉和视觉命名测验、单词阅读、流畅性）方面进行了比较。
两组在年龄、教育程度、FSIQ、词汇量、阅读或言语流畅性方面没有差异。然而，ESL 说话者在所有命名测量中得分均低于母语为英语者。此外，在单侧癫痫的 ESL 参与者中，相当一部分右半球患者的得分低于损伤的临界值。这与母语为英语者的更典型发现形成对比，其中相当一部分左半球患者表现出命名障碍。
这些结果强调了双语者言语评估的复杂性，表明即使是在其他英语言语测量中表现出色、被认为是熟练的 ESL 个体的命名表现，也不能用适用于母语为英语者的相同标准来解释。（JINS，2018，24，1057-1063）。
