Abstract:
Objective To explore the characteristics of intellectual impairment and event -related potential(ERP) in the elderly patients with asymptomatic cerebral infarction (ACI). Methods By using WAIS-RC and sensory event-related potential, VIQ, PIQ, FIQ, the latency of all the waves of ERP and the amplitude of P300 were measured in 53 elderly patients with ACI and 50 healthy controls. The 53 ACI patients were divided into a single-infarct cerebral lesion (30 cases) and multi-infarct cerebral lesion (23 cases). Results About 49.1%-58.5% of the patients with ACI showed some degrees of intelligence impairment, all score by WAIS-RC test was significantly lower in patients with ACI than that in healthy controls (P
