Impulsivity is a complex and important phenomenon in mood disorders. Impulse control disorders, as defined in DSM, are more frequent in mood disorders especially in Bipolar Disorder type I, and are associated with a more severe course of illness. Dimensional studies demonstrate that impulsivity is a core manifestation of bipolar disorder both as state- and trait-dependent markers in patients. Comorbid substance use disorders are often associated with a higher level of impulsivity whereas the relation between suicidal behaviors and higher impulsivity remains uncertain. Moreover, neuropsychological tests were used to study correlation between clinical impulsivity and laboratory measurements of impulsivity. Level of correlation remains weak and several explanations are proposed in the literature.
冲动性是情绪障碍中一种复杂且重要的现象。《精神疾病诊断与统计手册》（DSM）中定义的冲动控制障碍在情绪障碍中更为常见，尤其是在I型双相情感障碍中，并且与更严重的病程相关。维度研究表明，冲动性是双相情感障碍的核心表现，在患者中既是状态依赖型又是特质依赖型标记。共病物质使用障碍通常与更高水平的冲动性相关，而自杀行为与更高冲动性之间的关系仍不确定。此外，神经心理学测试被用于研究临床冲动性与冲动性实验室测量之间的相关性。相关程度仍然较弱，文献中提出了几种解释。
