Dopamine, reward, and frontostriatal circuitry in impulse control disorders in Parkinson's disease: insights from functional imaging.


Dopamine agonists have been implicated in the development of impulse control disorders (ICDs). This may be due to the ability of agonists to tonically stimulate dopamine receptors. Recent neuroimaging data provided evidence that dopamine agonists induce significant changes in those frontostriatal circuits that process reward and mediate our ability to… (More)
