Background: The efficacy of continuous subcutaneous apomorphine infusion (APO) has been evaluated in advanced Parkinson's disease in several open-label studies but never in a population of patients for whom subthalamic nucleus deep brain stimulation (STN-DBS) was contraindicated. Methods: The aim of this study was to evaluate the efficacy and cognitive safety of APO at 12-month follow-up in 23 advanced parkinsonian patients (mean age: 62.3 years; mean disease duration: 13.9 years) whose dopa-resistant axial motor symptoms and/or cognitive decline constituted contraindications for STN-DBS. Their motor and cognitive status were evaluated before APO and 12 months afterwards. Results: After one year, patients expressed high levels of satisfaction, with a mean rating on the Visual Analog Scale of 52.8% under APO. Daily OFF time, recorded in a 24-h diary, was reduced by 36% and ON time improved by 48%. There was a significant reduction (-26%) in mean oral levodopa equivalent dose. Dopa-resistant axial symptoms and neuropsychological performance remained stable. No adverse event was noted and none of the patients needed to take clozapine at any time. Conclusions: APO is both safe and effective in advanced parkinsonian patients with untreatable motor fluctuations, for whom STN-DBS is contraindicated due to dopa-resistant axial motor symptoms and/or cognitive decline. As such, it should be regarded as a viable alternative for these patients. (C) 2011 Elsevier Ltd. All rights reserved.
