Area of Science:

  • Neuroscience
  • Psychiatry
  • Clinical Psychology

Background:

  • The clinical concept of impulsivity is poorly defined, leading to diagnostic and research challenges.
  • Lack of a precise definition hinders the development of animal models and genetic studies for psychiatric disorders.

Purpose of the Study:

  • To provide a historical overview of the concept of impulsivity.
  • To review various scientific definitions of impulsivity.
  • To propose guidelines for an operational definition of impulsivity.

Main Methods:

  • Literature review of historical psychopathology and contemporary scientific articles on impulsivity.
  • Analysis of different conceptualizations of impulsivity across disciplines.
  • Synthesis of existing proposals for an operational definition.

Main Results:

  • Impulsivity has evolved from early concepts of 'will' to complex neuroscientific constructs.
  • Multiple, often conflicting, definitions of impulsivity exist in current literature.
  • There is a need for a unified, operational definition to advance research.

Conclusions:

  • Clarifying the definition of impulsivity is crucial for advancing psychiatric diagnostics and treatment.
  • A neuroscientifically-informed operational definition will facilitate research, including animal models and genetic studies.
  • This review provides a foundation for developing standardized research approaches to impulsivity.
