The Interface Between Impulse-Control Disorders and Addictions: Are Pleasure Pathway Responses Shared Neurobiological Substrates?

The term “addiction” has been used to describe several Impulse-Control Disorders. Models that have been developed for Substance-Related Disorders suggest a more general applicability in understanding and treating Impulse-Control Disorders. Neurocircuits and the neurochemical mediation of pleasure responses may represent a shared neurobiological substrate, linking addictions of both types. In this review, Pathological Gambling, Kleptomania, Compulsive Buying, Pyromania, and Problematic Internet Use are examined from a neurobiological perspective, with a specific focus on pleasure pathway responses.
