Several mental health disorders such as Attention-Deficit Hyperactivity Disorder (ADHD), bipolar-disorder, and impulse-control disorders include impulsivity and lack of inhibition that are commonly associated with risky behavior. Individuals with impulse control disorders, substance use disorders, and certain personality disorders are commonly linked to impulsivity. Acting before thinking about potential consequences of behavior is something that we can all do at times, especially for young people whose brains are still developing.
