Impulse control disorders (ICDs), including compulsive gambling, buying, sexual behaviour and eating, are not only a severe disorder that can affect the general, non‐clinical population, but also a serious, increasingly recognized psychiatric complication in Parkinson's disease (PD). Previous research detected some risk factors for their occurrence in PD patients and in the general population, including impulsivity. However, impulsivity is a multidimensional construct that comprises several aspects, including reflection impulsivity and delay discounting. The present work assessed different facets of impulsivity in both PD patients and in the healthy controls (HCs) to examine whether they scored differently, and if the occurrence of ICDs in PD patients and in the HCs was predicted by different aspects of impulsivity. The results showed that ICDs in PD patients were predicted by a strong preference for immediate rewards, whereas ICDs in the HCs were predicted by a deficient reflective ability. The present findings may help clinicians in the early identification of PD patients who could develop ICDs by simply assessing their impulsivity in terms of delay discounting. Furthermore, this work contributed to identify another risk factor for ICDs in the non‐clinical population.

帕金森氏病与健康对照组的冲动控制障碍:不同的预测模型。

冲动控制障碍(ICD),包括强迫性赌博,购买,性行为和进食,不仅是可以影响普通非临床人群的严重疾病,而且还是帕金森氏病(PD)中日益严重的公认的精神科并发症。先前的研究发现了在PD患者和一般人群中发生冲动的一些危险因素,包括冲动性。但是,冲动性是一个多维构造,包括几个方面,包括反射冲动性和延迟折现。目前的工作评估了PD患者和健康对照组(HCs)冲动的不同方面,以检查他们的得分是否不同,以及PD患者和HCs中ICD的发生是否由冲动的不同方面预测。结果表明,PD患者的ICD强烈期望立即获得奖励,而HCs的ICD通过缺乏反射能力来预测。目前的发现可能有助于临床医生通过简单地根据延迟贴现评估其冲动性,从而早期识别可能发展为ICD的PD患者。此外,这项工作有助于确定非临床人群中ICD的另一个危险因素。
