深部脑刺激疗法激活三条白质通路或可治疗难治性抑郁症的研究发表在 2014 年4月11日的《生物精神病学杂志》(Biol Psychiatry)上。

针对抑郁症的治疗,深部脑刺激(DBS)电极放置的最佳位置仍然是未知的。为了解决这个悬而未决的问题,研究人员回顾了16例难治性抑郁症患者2年内的胼胝扣带白质双侧DBS的全脑激活体积成像结果。成像是在6个月和2年进行的。

术后6个月,6例显效(抑郁量表得分减少50%);术后2年,12例显效。结果表明,沿电极三个双侧通路均被激活:

•经胼胝体前部和内侧钩束到达内侧额叶皮质

•经扣带束到达吻侧、前背侧和中间扣带回

•经下行中线纤维到达皮质下核(伏隔核,尾状核,壳核,丘脑前部)

在6个月时未显效者没有表现出通路的激活,但随后在2年显效时表现出通路被激活。电极的确切位置与疗效不具有相关性。

Journal Watch评论

这些结果表明,DBS的抗抑郁疗效包括感知、行为和情感管理的多区域网络连接系统的调制。

这个网络在DBS后被激活,若无效可能与非神经生理因素相关,如社会心理因素。针对不典型被激活的患者也许可以通过改变电极的配置和位置得到更好的疗效。
