Abstract

Objective: Efficacy and safety of transcranial direct current stimulation (tDCS) in the treatment of obsessive-compulsive disorder (OCD) were explored by meta-analysis.

Method: Four electronic databases (Cochrane, PubMed, Embase, Web of Science) were retrieved at 25/06/23. From our inclusion criteria, seven studies (N = 201 patients) were included, and we performed a meta-analysis using Stata15.0.

Results: Results suggested that the total Y-BOCS (Yale-Brown obsessive com-pulsive scale) scale was significantly lower in patients with OCD after tDCS treatment [SMD= -0.46, 95%CI (-0.84, -0.07), I²=39%, p = 0.02, Grade: high]. Subgroup analysis showed statistically significant results when treatment duration ≤ 20 days [SMD= -0.95, 95%CI (-1.80, -0.10), p = 0.03]. Moreover, tDCS and sham tDCS-treated OCD patients showed neither significantly different depressive symptoms nor significantly different adverse events [RR= -0.21, 95%CI (-0.58, 0.15), p = 0.25, Grade: moderate] and [RR = 3.98, 95%CI (0.04, 374.99), p = 0.55, Grade: very low], respectively.

Conclusion: tDCS maybe reduce the Y-BOCS total scores in OCD patients and depressive symptoms, but for adverse reactions. the results are inconclusive.

强迫症患者经颅直流电刺激：随机对照试验的荟萃分析。

目的：通过荟萃分析探讨经颅直流电刺激（tDCS）治疗强迫症（OCD）的疗效和安全性。方法：于23年6月25日检索Cochrane、PubMed、Embase、Web of Science 4个电子数据库。从我们的纳入标准中，纳入了7项研究（N = 201例患者），我们使用Stata15.0进行了荟萃分析。结果：结果显示强迫症患者经tDCS治疗后Y-BOCS （Yale-Brown强迫症量表）总分明显降低[SMD= -0.46, 95%CI (-0.84, -0.07), I2=39%, p = 0.02，等级：高]。亚组分析显示，治疗时间≤20 d时，结果具有统计学意义[SMD= -0.95, 95%CI (-1.80, -0.10), p = 0.03]。此外，tDCS与假tDCS治疗强迫症患者的抑郁症状无显著差异，不良事件也无显著差异[RR= -0.21, 95%CI (-0.58, 0.15), p = 0.25，分级：中度]和[RR= 3.98, 95%CI (0.04, 374.99), p = 0.55，分级：极低]。结论：tDCS可降低强迫症患者的Y-BOCS总分和抑郁症状，但对不良反应无显著影响。结果尚无定论。
