Impulsivity

Impulsivity is a tendency to act quickly without fully considering the consequences — such as interrupting, making rash decisions, or difficulty waiting.

Definition

Impulsivity involves acting on urges with little forethought. It is a feature of ADHD and can also appear in borderline personality traits and other conditions. Occasional impulsive choices are normal; frequent, impairing impulsivity may warrant screening and assessment.

What it can feel like

  • Interrupting others or blurting things out.
  • Making purchases or decisions on impulse.
  • Difficulty waiting your turn.
  • Acting on urges then regretting it later.
