Abstract Investigations into the neurobiological substrates underlying urge are important for developing better understanding and treatment for impulse-control disorders. We characterize the phenomenon based on normal bodily (interoceptive) urges. Features include the following: a preceding awareness of an uncomfortable bodily sensation, a sense of urgency that action must be taken, rising distress when action is delayed, a temporary (e.g., a few minutes in length) ability to suppress or manifest the action voluntarily, subsequent relief once action is taken, association with an action that is necessary to survival. We compare and contrast these characteristics with those described by Tourette syndrome patients as the urge to tic, and highlight several unknowns which merit further investigation.
摘要 对冲动控制障碍进行神经生物学基础的研究对于更好地理解和治疗冲动至关重要。我们根据正常的身体（内感受）冲动来描述这种现象。其特征包括：对身体不适感觉的预先察觉，必须采取行动的紧迫感，行动延迟时痛苦加剧，暂时（例如几分钟）自愿抑制或表现出行动的能力，一旦采取行动就会得到缓解，以及与生存所必需的行动相关联。我们将这些特征与图雷特综合征患者描述的抽搐冲动进行了比较和对比，并强调了几个值得进一步研究的未知问题。
