The ability to express oneself verbally is critical for success in academic, occupational, and social domains. Unfortunately, word-finding or "naming" difficulty is the most common cognitive complaint among individuals with temporal lobe epilepsy (TLE), and a substantial body of work over the past several decades has documented naming impairment in left (language-dominant) TLE, with further risk to naming ability following left temporal lobe resection for seizure control. With these findings well established, this paper reviews more recent work that has aimed to identify the neuroanatomical substrates of naming, understand how adverse structural and functional effects of TLE might impinge upon these brain regions, predict and potentially reduce the risk of postoperative naming decline, and begin to understand naming difficulty in TLE from a developmental perspective. Factors that have confounded interpretation and hindrances to progress are discussed, and suggestions are provided for improved empirical investigation and directions for future research.
语言表达能力对于在学术、职业和社交领域取得成功至关重要。不幸的是,找词困难或“命名”困难是颞叶癫痫(TLE)患者最常见的认知主诉,在过去几十年中,大量研究记录了左侧(语言优势侧)颞叶癫痫患者存在命名障碍,并且在为控制癫痫而进行左侧颞叶切除术后,命名能力面临进一步风险。鉴于这些发现已得到充分证实,本文回顾了最近的研究工作,这些研究旨在确定命名的神经解剖学基础,了解颞叶癫痫的不良结构和功能影响如何可能影响这些脑区,预测并潜在降低术后命名能力下降的风险,并开始从发育角度理解颞叶癫痫患者的命名困难。文中讨论了混淆解释的因素和进展的障碍,并为改进实证研究提供了建议以及未来研究的方向。
