背景：很少有研究涉及语义性痴呆的康复治疗。一种有潜力的方法是形式语义疗法，它由呈现概念名称及其语义特征的任务组成。它还可以通过间隔提取来增强，这是一种学习方法，通过在增加回忆间隔后回忆信息来提高记忆力。目的：本研究探讨形式-语义疗法和间隔提取方法对修复语义性痴呆女性脑干脑病患者丢失概念的效果。方法：形式-语义疗法包括给予TBO语义反馈，然后使用提示技术来促进命名。将简单重复的形式语义疗法与间隔提取的形式语义疗法进行了比较。在整个研究过程中，通过图片命名和词汇属性的生成来衡量TBO的表现。两份未经训练的清单也被用来衡量泛化效果。结果结果：结果表明，治疗后，任务型教师可以说出训练项目的3/8，而未训练项目列表上没有项目。她还显示，在概念的特定语义属性的唤起方面的表现有所提高，达到了正确回答的6/8。此外，在研究结束后的5周内，她一直保持着自己的表现。最后，与简单的重复练习相比，间隔提取没有提高学习效果，也没有观察到训练过的类别和未训练过的类别之间的概括。结论：与最近文献报道的结果一起，TBO的结果证实，语义性痴呆患者可以通过训练提高他们的命名成绩，但这是有限的。然而，形式-语义疗法在重新训练特定的语义属性方面似乎非常有希望。我们建议，语义性痴呆的治疗方法应该旨在恢复特定的和功能相关的概念，使个体在日常生活中更具自主性，而不是专注于命名。
Background: Few studies have addressed rehabilitation in semantic dementia. A potentially promising method is formal-semantic therapy, which consists of tasks in which the names of concepts and their semantic characteristics are presented. It could also be enhanced by spaced retrieval, a learning method improving retention through recalling information after increasing recall intervals. Aims: This study explores the efficacy of both a formal-semantic therapy and the spaced retrieval method to restore lost concepts in TBo, a woman with semantic dementia. Methods Procedures: The formal-semantic therapy consisted of giving TBo semantic feedback followed by a cueing technique to facilitate naming. Formal-semantic therapy with simple repetition was compared to formal-semantic therapy with spaced retrieval. TBo's performance was measured throughout the study with picture naming and generation of verbal attributes. Two untrained lists were also measured for generalisation effects. Outcomes Results: Results indicate that, after therapy, TBo could name 3/8 of the trained items, compared to no items on the untrained lists. She also showed an increase in performance for the evocation of specific semantic attributes of concepts, reaching 6/8 of correct responses. Moreover, she maintained her performance up to 5 weeks after the end of the study. Finally, when compared to simple repeated practice, spaced retrieval did not enhance learning and no generalisation was observed between trained and non-trained categories. Conclusions: Along with recent results reported in the literature, TBo's results confirm that people with semantic dementia can improve their naming performance with training but that this is limited. However, formal-semantic therapy seems very promising for retraining specific semantic attributes. Instead of focusing on naming, we suggest that therapies used in semantic dementia should aim at restoring specific and functionally relevant concepts to enable the individuals to be more autonomous in daily living.
