Daily fluctuations of motor performance and dyskinesias in patients with Parkinson's disease (PD) treated with levodopa represent a difficult challenge to our understanding. We report 10 patients diagnosed of severe PD (Hoehn and Yahr: III-IV/V) treated with levodopa (range of dose: 750-900 mg/day) in single drug therapy since their diagnosis (mean time of levodopatherapy: 4.8 2.4 months, range: 3-6 months). All patients developed motor complications within weeks to months after initiating L-dopatherapy. Two patients received an intravenous apomorphine infusion (mean dose: 8.5 mg/day) during a mean time of 7.5 hours, but motor complications persisted during the infusion in spite of continuous dopaminergic stimulus. The degree of nigrostriatal damage (disease severity) seems to be a very important risk factor for the development of treatment-related motor complications.
