Deep brain stimulation and continuous dopaminergic stimulation in advanced Parkinson's disease.
Patients receiving oral levodopa, the standard treatment for Parkinson's disease (PD), eventually develop motor fluctuations and dyskinesias. Treatment options for patients with these symptoms include high-frequency deep brain stimulation of the subthalamic nucleus (STN-DBS) or continuous dopaminergic stimulation (CDS). STN-DBS is the prevalent surgical therapy for PD and has shown efficacy, but behavioural disorders, including cognitive problems, depression and suicidality have been reported. CDS can be achieved with oral dopamine agonists with a long half-life, transdermal or subcutaneous delivery of dopamine agonists, or intestinal levodopa infusion. Of these, duodenal levodopa infusion appears to be the most promising option in terms of both efficacy and safety.
