  • Title: Auditory event-related potentials in Parkinson's disease.
    Author: Raudino F, Garavaglia P, Beretta S, Pellegrini G.
    Journal: Electromyogr Clin Neurophysiol; 1997 Oct; 37(7):409-13. PubMed ID: 9402429.
    Abstract:
    We studied 49 patients with Parkinson's disease (PD) by a neuropsychological battery examining the temporo-spatial orientation, short-term memory, comprehension, non-verbal intelligence, long-term memory and anomia and the Auditory Event-Related Potentials. In the patients the latencies of the N100 and N200 waves were prolonged and the amplitude of the P300 wave was reduced compared with controls. No difference was found in the ERP of patients with and without cognitive deficits. Equally, no correlation was found between the ERP, the cognitive impairment, the length or the severity of the disease evaluated by Hoehn-Yahr's and Webster's scales.
