There is great confusion about the concept of impulsivity despite its important clinical use. Limits with others symptoms or behaviors, like aggressiveness, are imprecise, and we find no general agreement on the definition of impulsivity in the present literature. From the point of view of neurosciences, adequate identification and measurement of a symptom as impulsivity could increase the validity of syndromic diagnoses, improve the development of animal models and genetic studies, and improve the treatment of several psychiatric disorders. Based on this perspective, the overall goals of this review article are: a) to establish the historical evolution of term, concept and behavior that we presently identify as impulsivity, starting from the classical psychopathology of the will; b) to review several concepts of impulsivity described in the scientific literature, and c) to provide basic guidelines for an operative definition, just as some authors have proposed, to create research lines and understand various discoveries that basic sciences have contributed.
尽管冲动性这一概念在临床应用中非常重要，但人们对它仍存在很大的困惑。冲动性与其他症状或行为（如攻击性）之间的界限并不明确，而且我们发现目前的文献中对于冲动性的定义尚未达成普遍共识。从神经科学的角度来看，对冲动性这一症状进行充分的识别和测量，可能会提高综合征诊断的有效性，促进动物模型和基因研究的发展，并改善几种精神疾病的治疗。基于这一观点，本文综述的总体目标如下：a）从经典的意志精神病理学出发，确立我们目前所认定的冲动性这一术语、概念和行为的历史演变；b）回顾科学文献中描述的几种冲动性概念；c）正如一些作者所提议的，为操作性定义提供基本指导方针，以创建研究方向并理解基础科学所做出的各种发现。
