The verbal output of patients with Parkinson's disease (PD) was analyzed for semantic and phonemic clusters on tasks of verbal fluency. One task required cued retrieval by semantic category (i.e. animals), and one required non-cued retrieval by initial letter (e.g. words beginning with 'F'). Nondemented PD patients (N = 25) produced significantly fewer words on the cued semantic retrieval task than age-, gender- and education-matched normal control subjects (N = 22), but were not impaired on the non-cued letter retrieval task. However, overall, PD patients were able to form more semantic clusters than phonemic clusters. These results are discussed in light of other studies of verbal fluency deficits in patients with PD.
对帕金森病（PD）患者的言语输出进行了分析，以研究其在言语流畅性任务中的语义和音素聚类情况。一项任务要求根据语义类别进行线索检索（即动物），另一项任务要求根据首字母进行非线索检索（例如以“F”开头的单词）。非痴呆的PD患者（N = 25）在有线索的语义检索任务中产生的单词明显少于年龄、性别和教育程度相匹配的正常对照受试者（N = 22），但在非线索字母检索任务中未受损。然而，总体而言，PD患者能够形成更多的语义聚类而非音素聚类。根据其他关于PD患者言语流畅性缺陷的研究对这些结果进行了讨论。
