The relative fluency with which 15 patients with Alzheimer-type dementia (DAT) retrieved words with specified first letters and belonging to semantically defined categories was assessed. Patients with DAT were always less fluent than controls but, like the 12 normal elderly subjects, they were more efficient in accessing words belonging to semantic categories. Their deficit in retrieving words with specified first letters was greater than that predicted on the basis of verbal intellectual ability. No differences in word fluency were detected in presenile and senile patients. These data support the conclusion that word fluency may prove useful in the detection of early dementia.
评估了15名阿尔茨海默型痴呆（DAT）患者提取以特定首字母开头且属于语义定义类别的单词的相对流畅程度。DAT患者的流畅程度总是低于对照组，但与12名正常老年受试者一样，他们在获取属于语义类别的单词时效率更高。他们在提取以特定首字母开头的单词方面的缺陷比基于言语智力能力预测的更大。早老性和老年性患者在单词流畅性方面未检测到差异。这些数据支持这样的结论：单词流畅性可能在早期痴呆的检测中有用。
