Objective.双语已被证明有利于执行功能（EF）和延迟阿尔茨海默病的发作。本研究旨在探讨双语优势是否适用于帕金森病（PD）的EF。法在一个横断面的门诊队列单语英语（n = 57）和双语威尔士/英语（n = 46）扬声器与PD我们评估的影响，双语与单语EF任务的性能相比。在双语者中，我们还评估了每种语言的日常使用程度和双语程度的影响。结果单语者在语言测试中表现出优势。单语者和双语者的EF测试性能没有差异。那些在日常生活中较少使用威尔士语的人在一次英语词汇测试中表现更好。双语能力的程度与非语言推理测试和工作记忆测试相关，但与其他EF测试无关。讨论没有发现威尔士-英语双语PD患者EF预期获益的原因，需要进一步研究。未来的PD研究应包括其他语言对，双语程度的影响分析，以及认知下降或痴呆的纵向分析与结构或功能神经影像学。
Objective. Bilingualism has been shown to benefit executive function (EF) and delay the onset of Alzheimer's disease. This study aims at examining whether a bilingual advantage applies to EF in Parkinson's disease (PD). Method. In a cross-sectional outpatient cohort of monolingual English (n = 57) and bilingual Welsh/English (n = 46) speakers with PD we evaluated the effects of bilingualism compared with monolingualism on performance on EF tasks. In bilinguals we also assessed the effects of the degree of daily usage of each language and the degree of bilingualism. Results. Monolinguals showed an advantage in performance of language tests. There were no differences in performance of EF tests in monolinguals and bilinguals. Those who used Welsh less in daily life had better performance on one test of English vocabulary. The degree of bilingualism correlated with one test of nonverbal reasoning and one of working memory but with no other tests of EF. Discussion. The reasons why the expected benefit in EF in Welsh-English bilinguals with PD was not found require further study. Future studies in PD should include other language pairs, analysis of the effects of the degree of bilingualism, and longitudinal analysis of cognitive decline or dementia together with structural or functional neuroimaging.
