JAMA Neurol:帕金森病患者冻结步态与生活质量的研究

2014-06-03 佚名 丁香园

近期,法国图卢兹大学的Olivier Rascol教授等开展了一项关于帕金森病(PD)患者冻结步态(freezing of gait, FOG)发生率、影响因素以对患者生活质量影响的研究,该研究的结果发表于2014年5月的JAMA neurology杂志。冻结步态是帕金森病药物治疗时较为常见的一种不良反应,表现为行走过程中(特别是起始和转身时)突然发生的步态停滞,在症状波动的缓解期(“开”期)和(

冻结步态是帕金森病药物治疗时较为常见的一种不良反应,表现为行走过程中(特别是起始和转身时)突然发生的步态停滞,在症状波动的缓解期(“开”期)和(“关”期)加重期均可出现。FOG的存在可明显影响PD患者的生活质量。关于FOG和一些相关因素及生活质量、药物治疗策略等目前报道较少。



该研究以UPDRS量表条目14得分≥1分为界筛选出672名存在FOG的患者,并对其生活质量、PD症状特征以及用药情况等进行分析,以探索FOG与上述因素的潜在关系。

结果显示,治疗“开”期FOG的发生率为38.2%.FOG与较低的生活质量、PD病程长、日常功能和运动功能差、情感淡漠、左旋多巴用量大以及更为频繁使用抗胆碱能药有关。在出现症状波动的患者中,有85.2%的患者FOG症状随“关”期向“开”期的转换而得到改善,并且,年轻患者症状的改善更为明显。



该研究的新意在于分别对处于症状波动“开”期和“关”期患者的冻结步态情况进行了研究。此外,研究进一步强调了冻结步态对生活质量产生影响,而通过多巴胺治疗并避免使用抗胆碱能药可能减少发生冻结步态的风险,这为今后进一步优化PD的药物治疗策略提供了重要的依据。
