JAMA 子刊:D-环丝氨酸联合认知训练有效改善耳鸣患者认知障碍

2014-11-07 佚名 生物谷

一项最新研究表明,药物D-环丝氨酸(D-cycloserine,DCS),当配合一种基于计算机的认知训练时,可能有助于耳鸣(tinnitus)的管理。 DCS被认为作为大脑内NMDA(N-甲基-D-天冬氨酸)受体的部分激动剂发挥作用,能够提高长时程增强作用,从而强化新突触连接。以往的研究表明,DCS可能促进神经可塑性,使大脑回路能更好地重塑,或能够解决非理性恐惧及提高专注力、注意力和执行力。

一项最新研究表明,药物D-环丝氨酸(D-cycloserine,DCS),当配合一种基于计算机的认知训练时,可能有助于耳鸣(tinnitus)的管理。

DCS被认为作为大脑内NMDA(N-甲基-D-天冬氨酸)受体的部分激动剂发挥作用,能够提高长时程增强作用,从而强化新突触连接。以往的研究表明,DCS可能促进神经可塑性,使大脑回路能更好地重塑,或能够解决非理性恐惧及提高专注力、注意力和执行力。

在发表于JAMA Otolaryngology-Head & Neck Surgery杂志上的一项研究,接受DCS治疗的患者耳鸣并未表现出显著降低,但与耳鸣相关的认知障碍却得到了改善。该文章的作者称,鉴于对耳鸣相关认知障碍的高度关注,该研究的发现非常重要。

该项研究涉及34例患有主观、单侧或双侧、非搏动性耳鸣且耳鸣持续至少6个月的患者,年龄分布为35-65岁。研究中,患者接受了每周2次的基于计算机的认知训练,每次训练前口服250mg DCT或安慰剂,共进行5周。

数据显示,与安慰剂组相比,DCT组患者耳鸣功能指数平均得分从基线取得了更显著的下降(TFI变化 -5.8 vs -1.0),尽管这种差异具有统计学显著差异,但未达到13的值,这是最低限度的临床显著差异。此外,经过年龄和耳鸣持续时间调整后,这种统计学显著性消失了。

然而,该药也与患者自报的认知缺陷改善相关(CFQ问卷:分数变化,-4.5 vs -2.0)。经过其他因素调整后,仍然显著性相关。

结论:基于计算机的认知训练联合一种可能的神经可塑性增敏药——D-环丝氨酸,是一种可行且耐受性良好的策略。由于样本规模的限制,与安慰剂相比,D-环丝氨酸未能改善耳鸣,但在改善自报认知困难方面更有效。
