The impact of subthalamic nucleus (STN) deep brain stimulation (DBS) on neuropsychiatric fluctuations in Parkinson´s disease (PD) remains unclear. The Neuropsychiatric Fluctuations Scale (NFS) can help to fill this gap, directly measuring fluctuations between the OFF- and ON-medication conditions. The NFS provides NFS-plus (hyperdopaminergic) and NFS-minus (hypodopaminergic) sub-scores. Based on these, the NFS global scores express the overall magnitude of neuropsychiatric symptoms in both the OFF- and ON-medication states. The total fluctuation score (TFS) represents the difference between ON- vs. OFF-medication NFS global scores, thus assessing fluctuations amplitude. The NFS was used to evaluate changes in neuropsychiatric fluctuations between the OFF- and ON-medication conditions before and 1-year after bilateral STN-DBS in 45 PD patients (32 males; mean age, 61.3 ± 7.2 years; PD duration, 10.2 ± 3.0 years). After surgery, the amplitude of neuropsychiatric fluctuations was significantly reduced (p < 0.001), confirming the efficacy of STN-DBS on these symptoms.
丘脑底核（STN）深部脑刺激（DBS）对帕金森病（PD）神经精神波动的影响仍不明确。神经精神波动量表（NFS）有助于填补这一空白，它能直接测量服药期和未服药期之间的波动情况。NFS提供NFS加（多巴胺能亢进）和NFS减（多巴胺能减退）两个子分数。基于这些，NFS总分表示未服药和服药状态下神经精神症状的总体严重程度。总波动分数（TFS）代表服药与未服药时NFS总分之间的差异，从而评估波动幅度。在45例PD患者（32例男性；平均年龄61.3±7.2岁；PD病程10.2±3.0年）中，使用NFS评估双侧STN-DBS术前及术后1年服药期和未服药期神经精神波动的变化。术后，神经精神波动幅度显著降低（p<0.001），证实了STN-DBS对这些症状的疗效。
