Subthalamic nucleus deep brain stimulation (STN-DBS) is a surgical technique to treat motor symptoms in patients with Parkinson's disease (PD). Studies have shown that STN-DBS may cause a decline in verbal fluency performance. We aimed to verify the effects of STN-DBS on the performance of phonemic verbal fluency in Brazilian PD patients. Sixteen participants were evaluated on the Unified Parkinson's Disease Rating Scale - Part III and for phonemic fluency ("FAS" version) in the conditions of on- and off-stimulation. We identified two different patterns of phonemic verbal fluency outcomes. The results indicate that there may be no expected pattern of effect of bilateral STN-DBS in the phonemic fluency, and patients may present with different outcomes for some reason not well understood.
丘脑底核深部脑刺激术（STN-DBS）是一种治疗帕金森病（PD）患者运动症状的外科技术。研究表明，STN-DBS可能会导致言语流畅性表现下降。我们旨在验证STN-DBS对巴西PD患者音素言语流畅性表现的影响。16名参与者在统一帕金森病评定量表第三部分以及刺激开启和关闭状态下接受了音素流畅性（“FAS”版本）评估。我们识别出了两种不同的音素言语流畅性结果模式。结果表明，双侧STN-DBS在音素流畅性方面可能不存在预期的效应模式，并且患者可能由于某种尚未完全理解的原因而呈现出不同的结果。
