JNNP:强迫症患者丘脑底核的脑深部刺激:一个开放、前瞻性、观察队列的长期随访

强迫症(OCD)是西方国家致残的主要原因,是严重影响生活质量的因素。约10%的患者有严重的强迫症症状,需要创新性的医学治疗方式,如深部脑刺激(DBS)。在可能的靶点中,非运动性丘脑底核(STN)是基底神经节回路的关键节点,与强迫症(OCD)相关的边缘皮质区紧密相连。

方法:采用前瞻性、观察性、单中心、开放性队列研究方法,对19例难治性强迫症(OCD)患者在单中心连续手术的慢性非运动性STN-DBS治疗效果进行分析。强迫症严重程度采用耶鲁和布朗强迫量表(YBOCS)进行评估。术后6、12、24个月YBOCS评分与基线比较。应答者由YBOCS评分改善>35%确定。全球评估功能(GAF)量表用于评估改进的影响。

结果:随访24个月,YBOCS评分由33.3±3.5提高到15.8±9.1,提高了53.4%(95%CI 11.2-20.4;p<0.0001)。19例患者中有14例被认为有效,19例中有5例改善超过75%,10例超过50%。GAF评分从34.1±3.9提高到66.4±18.8(95%CI 56.7-76.1;p=0.0003),提高了92%。最常见的不良事件包括短暂性焦虑和轻度焦虑。

结论:非运动性STN慢性DBS是一种有效且相对安全的方法,可用于治疗对常规治疗耐药的重症强迫症。
