Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity and bradykinesia and non-motor symptoms such as mood disorders, cognitive issues, and impulse control disorders (ICDs). ICDs are often associated with dopamine agonists (DAs), although this association is still debated. DAs are prescribed as an alternative or in combination with levodopa, to reduce levodopa-induced complications such as dyskinesia. Deep brain stimulation (DBS) proves to be a viable alternative: although it is invasive, being localized, it provides a more targeted effect. Moreover, some studies have shown that DBS has an improvement effect not only on motor symptoms but also on impulsive behavior.
