Early Impairment of Narrative Discourse Complexity in Parkinson Disease Patients without Mild Cognitive Impairment

This dataset was collected to investigate narrative discourse with the Cookie Theft (CT) picture in PD patients with and without MCI, in addition to other classical measures of language production. Moreover, the authors explore which components of language production are associated with the progression of neurological impairment and the diagnosis of MCI. Participants were evaluated with a set of linguistic instruments, including the CT picture, verbal fluency test (phonemic and semantic) and naming task. The data demonstrates that impairment in narrative discourse in PD can be present regardless of cognitive status and degree of neurological impairment, in contrast to other language production difficulties, which are associated with MCI diagnosis and disease progression.本数据集旨在借助偷饼干图片任务（Cookie Theft, CT），针对伴与不伴轻度认知障碍（Mild Cognitive Impairment, MCI）的帕金森病（Parkinson's Disease, PD）患者开展叙事话语研究，同时纳入其他经典语言产出测评工具。此外，本研究探究语言产出的哪些维度与神经功能损伤进展及轻度认知障碍的诊断存在关联。研究对象通过一系列语言测评工具完成评估，其中包括偷饼干图片任务、言语流畅性测验（语音性与语义性）以及命名任务。数据分析结果显示，帕金森病患者的叙事话语损伤可能独立于认知状态与神经功能损伤程度出现；而其他语言产出障碍则与轻度认知障碍诊断及疾病进展显著相关。
