    Abstract:
    We studied the relationship between P300 latency and regional cerebral blood flow (rCBF) in nondemented patients with cerebral infarction. Subjects were 24 nondemented patients (mean age 64.1 years) who had a CT-proven infarct in the territory of the deep perforators of the internal carotid artery system and 53 controls (mean age 64.1 years). Prolongation of P300 latency with advancing age was observed in the both groups. There was no significant difference in P300 latency and rCBF between the two groups. There was a negative correlation between P300 latency and rCBF, especially in the bilateral fronto-parietal regions in the patient group. These results indicate that cognitive function assessed by P300 latency may be related to rCBF in the fronto-parietal region in the nondemented patients with lacunar infarctions.
