Zusammenfassung:Patients with advanced Parkinson's disease (PD) and contraindications for subthalamic nucleus deep brain stimulation (DBS) could particularly benefit from subcutaneous infusion therapy with apomorphine. This original study was designed to evaluate the general efficacy of add-on apomorphine in motor and nonmotor symptoms in advanced PD, while characterizing the changes induced in brain glucose metabolism. The aim was to look at the underlying anatomical-functional pathways. 12 patients with advanced PD were assessed before and after 6months of add-on apomorphine, using resting-state 18F-fluorodeoxyglucose positron emission tomography and exhaustive clinical assessments. After 6months of therapy, oral treatment was significantly reduced. Both motor and nonmotor scores improved, with a beneficial effect on executive functions, quality of life and apathy. Significant metabolic changes were observed, with overall increases in the right fusiform gyrus and hippocampus, alongside a decrease in the left middle frontal gyrus. Consistent correlations between significant changes in clinical scores and metabolism were established. Well tolerated, add-on apomorphine appears to be an interesting option for patients with fluctuations and contra-indications for DBS. Changes in brain metabolism, with beneficial effects on motor and nonmotor symptoms were observed after 6months. These preliminary results have to be confirmed by further studies. •An extensive study of 12 parkinsonian patients treated with apomorphine is proposed.•Motor and nonmotor improvements are correlated with brain glucose metabolism changes.•Both increase and reduction of glucose uptake are observed after six months.
