The aim of this study was to generalize the positive impact of auditory-visual bimodality on lexical retrieval in Alzheimer's disease (AD) patients. In practice, the naming skills of healthy elderly persons improve when additional sensory signals are included. The hypothesis of this study was that the same influence would be observable in AD patients. Sixty elderly patients separated into three groups (healthy subjects, stage 1 AD patients, and stage 2 AD patients) were tested with a battery of naming tasks comprising three different modalities: a visual modality, an auditory modality, and a visual and auditory modality (bimodality). Our results reveal the positive influence of bimodality on the accuracy with which bimodal items are named (when compared with unimodal items) and their latency (when compared with unimodal auditory items). These results suggest that multisensory enrichment can improve lexical retrieval in AD patients.
本研究的目的是概括视听双模态对阿尔茨海默病（AD）患者词汇检索的积极影响。实际上，当纳入额外的感官信号时，健康老年人的命名技能会有所提高。本研究的假设是，在AD患者中也能观察到同样的影响。60名老年患者被分为三组（健康受试者、1期AD患者和2期AD患者），接受了一系列命名任务测试，这些任务包括三种不同的模态：视觉模态、听觉模态以及视觉和听觉模态（双模态）。我们的结果揭示了双模态对双模态项目命名准确性（与单模态项目相比）及其潜伏期（与单模态听觉项目相比）的积极影响。这些结果表明，多感官强化可以改善AD患者的词汇检索。
