PurposeThis study compared performance on three-word fluency measures among individuals with primary progressive aphasia（PPA）and primary progressive apraxia of speech（PPAOS），and examined the relationship between word fluency and other measures of language and speech.MethodThis study included 106 adults with PPA and 30 adults with PPAOS. PPA参与者被分为三个临床亚组：语义（svPPA），逻辑缺乏（lvPPA），和非流利/无语法伴或不伴言语失用症（nfPPA）。类别流畅性，字母流畅性，和行动/动词流畅性的任务进行了管理所有participant.ResultsThe四个临床组执行异常的字流畅性措施，虽然没有到一定程度，代表他们的PPA或PPAOS诊断的高灵敏度。在所有单词流畅性测量中，与PPAOS患者相比，所有PPA亚组产生的单词更少。中度之间的相关性被发现在一些临床groups.ConclusionsWord流畅性措施往往是具有挑战性的个人与PPA和PPAOS的失语症的严重程度和命名性能，但他们不是同等的困难，与字母流畅性是最困难的。单词流利性测试之间的差异也在一定程度上因临床组的不同而不同，PPAOS的损害最小。然而，本研究的结果并不支持统计学显着差异的PPA亚组之间的单词流畅性任务的表现。相关性表明，PPA中的单词流利性表现至少部分与失语症的严重程度有关。
PurposeThis study compared performance on three-word fluency measures among individuals with primary progressive aphasia (PPA) and primary progressive apraxia of speech (PPAOS), and examined the relationship between word fluency and other measures of language and speech.MethodThis study included 106 adults with PPA and 30 adults with PPAOS. PPA participants were divided into three clinical subgroups: semantic (svPPA), logopenic (lvPPA), and nonfluent/agrammatic with or without apraxia of speech (nfPPA). Category fluency, letter fluency, and action/verb fluency tasks were administered to all participants.ResultsThe four clinical groups performed abnormally on the word fluency measures, although not to a degree that represented high sensitivity to their PPA or PPAOS diagnosis. All PPA subgroups produced fewer words compared to individuals with PPAOS on all word fluency measures. Moderate correlations were found between word fluency and aphasia severity and naming performance in some of the clinical groups.ConclusionsWord fluency measures are often challenging for individuals with PPA and PPAOS, but they are not of equal difficulty, with letter fluency being the most difficult. Differences among word fluency tests also vary to some degree as a function of the clinical group in question, with least impairment in PPAOS. However, the findings of this study do not support statistically significant differences in word fluency task performance among the PPA subgroups. Correlations suggest that word fluency performance in PPA is at least partly related to aphasia severity.
