Abnormal patterns of impulsivity have also been noted instances of acquired brain injury and neurodegenerative diseases.

'When such actions have positive outcomes, they tend not to be seen as signs of impulsivity, but as indicators of boldness, quickness, spontaneity, courageousness, or unconventionality' Thus, the construct of impulsivity includes at least two independent components: first, acting without an appropriate amount of deliberation, which may or may not be functional and second, choosing short-term gains over long-term ones.Impulsivity is both a facet of personality and a major component of various disorders, including FASD, ADHD, substance use disorders, bipolar disorder, antisocial personality disorder, and borderline personality disorder. A functional variety of impulsivity has also been suggested, which involves action without much forethought in appropriate situations that can and does result in desirable consequences. Impulsivity can be classified as a multifactorial construct. Impulsive actions are typically 'poorly conceived, prematurely expressed, unduly risky, or inappropriate to the situation that often result in undesirable consequences,' which imperil long-term goals and strategies for success.

In psychology, impulsivity (or impulsiveness) is a tendency to act on a whim, displaying behavior characterized by little or no forethought, reflection, or consideration of the consequences. Wikipedia Rate this definition: 0.0 / 0 votes
