In 32 patients (18 male) aged 45 to 83 years old (22 with idiopathic parkinsonism and 10 with parkinsonism of other causes), the dopaminergic response to apomorphine after domperidone administration was assessed using the digital skill test and(More)

Short latency somatosensory evoked potentials were measured in 10 patients with Parkinson's disease before and after the administration of Apomorphine 5 mg sc. Eight of these subjects were reassessed after one month of treatment with Levo-Dopa. These potentials were measured in other nine subjects before and after one month of treatment with Selegiline 10(More)
