This study investigated the effects of seizure laterality and language dominance on material-specific memory in temporal lobe epilepsy (TLE). Left TLE (LTLE) patients with left-hemisphere language dominance (LHLD) showed significantly higher nonverbal than verbal memory capacity, whereas right TLE patients with LHLD showed significantly better verbal than nonverbal memory capacity. LTLE patients with non-left-hemisphere language dominance (NLHLD) showed significantly better verbal memory capacity compared with LTLE patients with LHLD. Thus, selective verbal or nonverbal memory deficits that are dependent on side of seizure onset were apparent in patients with LHLD but not in patients with NLHLD. Relative sparing of verbal memory capacity in LTLE patients with NLHLD may reflect interhemispheric reorganization of verbal memory function.
本研究调查了发作侧别和语言优势对颞叶癫痫（TLE）患者特定材料记忆的影响。左侧颞叶癫痫（LTLE）且具有左侧半球语言优势（LHLD）的患者，其非言语记忆能力显著高于言语记忆能力，而右侧颞叶癫痫且具有LHLD的患者，其言语记忆能力显著优于非言语记忆能力。与具有LHLD的LTLE患者相比，非左侧半球语言优势（NLHLD）的LTLE患者表现出显著更好的言语记忆能力。因此，在具有LHLD的患者中，明显存在依赖于发作起始侧别的选择性言语或非言语记忆缺陷，而在具有NLHLD的患者中则不存在。NLHLD的LTLE患者言语记忆能力的相对保留可能反映了言语记忆功能的半球间重组。
