ABSTRACT

Background

The presence of naming difficulties in Parkinson’s Disease (PD), especially object naming difficulties, as well as the associated cognitive difficulties, remains a controversial topic.

Aims

This study assesses object naming capacities in PD patients and the cognitive impairment related to the patients,’ word naming difficulties, whether linguistic, executive or associated to slower cognitive processing speed.

Methods and Procedures

To that aim, 46 PD patients and 48 control participants were presented with a picture naming task of objects. Specific language difficulties were examined by analysing the naming errors, the effects of word frequency and length on naming performances, as well as the patients’ semantic performances in semantic matching and synonym judgment tasks. The executive assessment consisted of working memory, inhibition, flexibility and updating tasks, and cognitive processing speed was explored through an odd/even judgment task.

Outcomes and Results

The results show that PD patients have lower object naming scores. Regarding the associate cognitive impairment, the outcomes reveal that naming difficulties are related to updating difficulties and slower cognitive processing speed.

Conclusions

This study confirms the presence of object naming difficulties in PD. Moreover, the relationships between naming difficulties and executive deficits as well as slower processing speed are in line with many studies that also indicate relationships between executive dysfunction or slower processing speed and language difficulties in PD, but for other tasks.

帕金森病会影响对象命名能力吗？探索图片命名能力和相关的认知缺陷

摘要

背景

帕金森病 (PD) 中存在命名困难，尤其是对象命名困难，以及相关的认知困难，仍然是一个有争议的话题。

目标

本研究评估了 PD 患者的对象命名能力以及与患者相关的认知障碍、单词命名困难，无论是语言、执行还是与较慢的认知处理速度相关。

方法和程序

为此，向 46 名 PD 患者和 48 名对照参与者提供了对象的图片命名任务。通过分析命名错误、词频和长度对命名表现的影响，以及患者在语义匹配和同义词判断任务中的语义表现，检查了具体的语言困难。执行评估包括工作记忆、抑制、灵活性和更新任务，通过奇/偶判断任务探索认知处理速度。

结果和结果

结果表明，PD 患者的对象命名得分较低。关于关联认知障碍，结果表明命名困难与更新困难和认知处理速度较慢有关。

结论

这项研究证实了 PD 中存在对象命名困难。此外，命名困难和执行缺陷之间的关系以及较慢的处理速度与许多研究一致，这些研究也表明执行功能障碍或较慢的处理速度与 PD 中的语言困难之间的关系，但对于其他任务。
