摘要 目的使用爱荷华赌博(iowa gambling task,IGT)试验明确缺血性脑白质疏松(ischemic Leukoaraiosis,ILA)患者是否有决策功能障碍及其程度。方法 22位ILA患者和22位健康志愿者(对照组)接受IGT和简易智能状态检查(mini-mental state examination,MMSE)量表评估。在IGT中,有高惩罚的高奖赏与低惩罚的低奖赏选择。受试者被鼓励尽可能赢取更多的钱。IGT被分5个阶段进行分析。结果 ILA患者MMSE评分(24.5±3.6),低于对照组的(28.9±1.2)(P<0.05)。在IGT中,对照组逐渐倾向于对自己有利的选择模式,而ILA组无有利选择倾向,在第3-5阶段ILA组得分分别为(-1.8±6.4),(1.9±4.6)和(1.5±4.9),明显低于对照组的(2.9±5.0),(5.5±3.7)和(5.3±4.4)(P<0.05)。结论 ILA患者因缺血性皮质下白质损害导致明显的决策功能障碍。
