    Abstract:
    Somatosensory evoked potentials (SEPs) to median nerve stimulation have been performed before and after apomorphine-test in 10 parkinsonian patients. Latency and amplitude of the P14-N20 parietal complex and of the P20-N30 frontal complex were evaluated. The N30 amplitude was significantly reduced before apomorphine administration (p < 0.001) with a consequent increase of the N20/N30 amplitude ratio (p < 0.001). Eight patients clinically improved after Apomorphine. Following Apomorphine there was no change in the amplitude of the parietal complex P14-N20. On the other hand the frontal complex P20-N30 showed a significant amplitude potentiation (p < 0.005), with a reduction of the N20/ N30 amplitude ratio (ns). This finding was almost constant among the 8 responder patients. These results suggest the utility of combining clinical and neurophysiological data to assess the responsiveness to dopaminergic treatment.
