The role of the cerebellum in cognitive performance and attentional processes is a focus of research in recent years. We investigated the P300 component in a patient with a left posterior cerebellar ischemic stroke during both the acute phase and over 4 weeks of follow-up. After stroke, auditory event-related potentials showed a reduction in P3 amplitude, which appears to improve instead after 4 weeks of follow-up. These event-related potential findings could suggest a specific neural pattern of disruption in selective attention during the discrimination processes of the stimulus following a posterior cerebellar lesion. A recovery is observed in the long term.
