Evidence indicates that dysfunction of the dopamine system can be both a cause and consequence of stimulant use and that this bi-directional relationship may be mediated by the ability of individuals to ... In addition to providing evidence that many of the neural alterations detected in stimulant-dependent individuals can emerge solely through experience with drugs, these studies have identified potential ...

Dopaminergic changes, such as increased dopamine release, reduced dopamine transporter activity and other changes, have been shown to be a consistent feature of ICDs in PD. ... Impulse control disorders (ICDs) may arise in Parkinson's disease (PD) in relation to the use of dopamine agonists (DA). A dysfunction of reward circuits is considered the main underlying mechanism. ... Acknowledgments This work was supported by Canadian Institutes of Health Research (MOP 136778).
