SUMMARY
The aim of the present study was to use the Iowa Gambling Task (IGT) to investigate differences in decision-making (DM) between patients who sustained TBI and healthy subjects, while controlling for age, education and gender.
METHODS
A hundred and ten participants, half of whom had severe or mild TBI, completed the IGT.
RESULTS
Differences between control participants and patients with TBI were found regarding total net score, block score, number of selections from each deck and classification of performance as impaired or unimpaired. No significant differences in IGT performance were found between patients with and without frontal lesions and between patients with mild and severe TBI.
CONCLUSIONS
Results indicate poor DM on the IGT in patients with TBI, regardless of lesion location and severity. The instrument proved to be equally sensitive to both frontal and extrafrontal lesions and did not differentiate between patients with mild and severe TBI.
摘要
本研究旨在使用爱荷华赌博任务（IGT），在控制年龄、教育程度和性别的同时，调查创伤性脑损伤（TBI）患者与健康受试者在决策（DM）方面的差异。
方法
110名参与者完成了IGT，其中一半患有重度或轻度TBI。
结果
在总净得分、组块得分、从每叠牌中选择的次数以及表现分类为受损或未受损方面，发现了对照组参与者与TBI患者之间的差异。在有和没有额叶病变的患者之间以及轻度和重度TBI患者之间，IGT表现没有显著差异。
结论
结果表明，无论病变位置和严重程度如何，TBI患者在IGT上的决策能力较差。该工具被证明对额叶和额叶外病变同样敏感，并且不能区分轻度和重度TBI患者。
